TYPE-WRITING MACHINE.

SPECIFICATION forming part of Letters Patent No. 657,927, dated September 18, 1900.

7 Application filed June 5, 1899. ,fierial N0- 719,4l9. (No model.)

To all whom it may concern:

Be it known that I, JACOB FELBEL, a citizen of the UnitedStates, and a resident of the borough of Manhattan, in the city of New York, int-he county of New York and State of New York, have invented certain new and useful Improvements in Type-Writing Machines, of which the following is a specification.

The present invention relates to type mechanism for type-writing machines, and more particularly to type mechanism for visiblewriting machines, so-called.

One object of the invention is to provide a construct-ion of the type-action wherein each type-action may be made complete and assembled in the machine as a unit and may also be removed therefrom as a unit with ease and despatch in order to be repaired or to be replaced by another.

Another object is to provide a type-writing machine of relatively few parts compactly arranged and the whole of a minimuni size and one in which the writing is visible to the operator as it progresses, not requiring that the operator shall move any part of the body or the head beyond casting the eyes in the proper direction in order to see the line of writing being done.

Another object is, in a machine in which the printing-point is at the front side of the platen and in which a plurality of type upon the individual type-bars are employed,to shift the type-carriers in order to bring a different set or case of type into position for coaction with the platen upon the operation of the keys. By preference the shift of the typecarriers is in a verticaldirection.

Another object is, in a double-case machine, to provide key-operated means for the upper case shift which will maintain the machine in the upper-case printing position only so long as the keyis depressed, and also to provide mechanism which will automatically retain the type-bars in the upper-case printing position until properly released, thus providing for the automatic return of the type bars to lower-case position after the writing of a capital at the beginning of a word, and also providing for the writing of upper-case letters or characters in succession and freeing both hands for use in such writing.

Another object is to provide a novel construction and arrangement of the type-action. These and other objects and advantages of my improvements will hereinafter more fully appear. a

To these ends the invention includes features of construction and combinations of devices hereinafter described, and more par ticularly pointed out in the appended claims. The preferred form of the invention isillustrated in the accompanying drawings, forming part of this specification, in whieh Figure 1 is a plan view of the machine with portions of the platen and top plate broken away, also with the whole series of type-bars broken away from the type ring or segment to more clearly exhibit the latter. Fig. 2 is a bottom plan view of the under side of the machine looking upward. Fig. 3 is a central longitudinal vertical sectional view looking from the right-hand side of the machine and showing one of the type-bars and its actuating mechanism in the positions thereof at the moment of the printing of a letter by a type on the bar. Fig. 4 is a vertical crosssectional view,the plane of thesection thro ugh the frame being indicated by the line X X in Fig. '3 and the section through the key-levers being indicated by the line X X in Fig. 2. Fig. 5 is a detail vertical sectional view on the line Y Y of Fig. 4 and showing a ballseparator. Fig. 6 is an enlarged plan view of the detached type-segment, showing the two middle and the extreme type bars mounted thereon and the manner ofconnecting them with their actuating-levers to lever 7 being broken away or removed. Fig.

9 is a similar view illustrating the mannerof releasing the locking device to allow the return of the type-ring to position for printing lower-case characters. Fig. 10 isa modification in arrangement of the type-action. Fig. 11 is a further modification thereof, and Fig. 12 is a modification in the form of the abutment for the bent lever.

The same character of reference will be used to indicate the same part in the various figures of the drawings.

Referring to Figs. 1 to 9 inclusive, 1 indicates a base-frame of suitable construction; 2, uprights or standards formed or cast in one with the base; 3, a top plate or table secured to the standards 2 in any suitable manner, as by screws 4 5, rubber feet secured to the base, and 6 a platen which is suitably mounted in any suitable form of carriage. (Not shown.)

7 7 indicate key-levers made of sheet metal and formed each at its rear end with an openended longitudinally-extending slot 8, which is formed intermediate its ends with curved or are-shaped indentations 9, thus forminga double keyhole-slot.

10 10 indicate suitable keys or finger-pieces at the forward ends of the key-levers.

11 is a fulcrum-rod secured in hangers 12 by set-screws 13, the hangers being formed in one with and projecting downwardly from the top plate of the baseframe 1. The rod 11 is flattened on two opposite sides, so that when the flattened sides thereof are horizontal the slotted ends of the key-levers 7 may be slipped thereover until the indentations 9 are in position over and under the rod 11, whereupon by giving the rod 11 a quarterturn (the screws 13 having been loosened) the rod engages with the said indentations 9 and locks the key-levers against end wise motion but permits a rocking motion thereof about the rod. The said screws 13 are tightened to hold the rod 11 in the position thereof shown in full lines in Fig. 3.

The rear parallel portions a of the levers 7 are placed closer together than the parallel forward or key-bearing portions 1) thereof, and said parallel portions a b are connected by oblique portions 0. The rear parallel portions at of the key-levers 7 are condensed or brought closer together, so as to enable the use of a series of substantially-vertical and substantially-parallel bent levers, as will appear hereinafter, while the front parallel portions 1) of the key-levers are arranged farther apart to provide the requisite space for the key heads or buttons. The machine is provided with two reed bars or combs 14 and 15 for guiding the key-levers in a vertical direction. Suitable springs 16, secured at one end bet-ween cross-bars 17, which also retain the lower ends of the reed 14, press upwardly against the key-levers 7 at a point forward of the fulcrum-rod 11 and between the members of the reed let.

The shifting segment shown for supporting the type-bars will be described next.

At a point about midway between the front and rear standards 2 and at each side of the machine is provided a vertical guide-plate 18,

which is formed in one with or is attached to the table 3,as by screws 19, which pass through lugs 20, formed integral with the plates 18, and engage with threaded holes in the under side of the table 3. The inner edges of the plate 18 are provided with vertically-extending V-shaped grooves 21 for a purpose presently to appear. Between the guide-plates 18 is placed a type-bar segment or part ring 22, which lies in a vertical plane and is formed or provided with vertical end plates 23, having V-shaped grooves 24 adjacent to and opposing the grooves 21 in the plates 18. In each of the raceways formed by the grooves 21 and 24 are placed two balls 25, which are held at fixed distances apart by a suitable separator,,as a plate 26, placed between the parts 18 and 23 and provided with perforations of larger diameter than said balls and embracing the same, as illustrated in Figs. 1, 4, and 5. The described construction permits of an up-and-down motion of the typesegment with a minimum of friction at its bearings, the plate 26 rising and falling with the balls. For the purpose of limiting the up-and-down motion of the ring or segment 22 each plate 18 has an arm 27 rigidly connected therewith, as by screws 28 passing through perforations in the arm and engaging threaded holes in the plate. Said arms project horizontally adjacent the plates 23, as shown in Fig. 4:, and each plate 23 is provided with two lugs 29 and 30, one above and the other below the corresponding arm 27, and each lug is provided with a screw-threaded perforation for the reception of an adjustable screw-stop 31 32. In the normal position of the parts the adjustable stops 31 rest or abut against the top sides of arms 27 and so limit the downward motion of the segment 22,while the stops 32 strike against the under sides of the arms 27 to limit the upward motion of the said segment. The separators 26 are each provided with horizontally and forwardly projecting arms 26, between which the arms 27 pass, as indicated in Fig. 5, the arms 26 being at a distance apart such that the separators and balls 25 may have ample motion in shifting the type-bars, as hereinafter described. The arms 26 and 27 prevent the separators and balls from being displaced or lost.

Flat type-bars 33 (which may be ribbed, however, for strength) are pivotally connected with the segment 22 in any suitable manner; but in the preferred form of the invention these type-bars are connected with the segment in the following manner: The segment is provided or formed with a series of wedge-shaped lugs 34:, separated from each other by uniform intervals or spaces and having their adjacent sides parallel, said lugs being at the upper side of the segment 22 and the segment 22 being formed in the arc of a circle whose center is at the printing-point on the platen 6. The lugs 34 are slotted transversely to about half their depth for the reception of a curved bar, rod, or wire 35,which is flattened at its front and rear sides, as indicated in Figs. 1,3, and 6. Each type-bar 33 is provided with an open-ended keyhole-slot 36, having parallel sides connecting the circular part thereof with the outer edge of the typebar, as indicated in Fig, 8. The parallel sides of the slot 36 are at a distance apart suflicient barely to permit the insertion of thetype-bar over the fulcrum-rod 35 when the type-baris in the position shown in Fig. 8'that is, in its normal position in the machineand the circular part of the slot 36 is of a size adapting it to fit closely upon the circular edges of the rod 35 and to lock the type-bar against play upon the pivot-rod 35 whenever the type-bar is given a pivotal or swinging motion. The arc-shaped wire or rod 35 is held in position by set-screws 37, engaging threaded holes in the plates 23 and bearing against the rod. Each type-bar 33 when in normal position may be separately removed from the type-ring by lifting it out of the slot formed by the lugs 34 on each side thereof, and each type-bar is of course of a thickness to fit nicely in the slot in which it is placed, but to have sufficient freedom of motion during the operation of the machine.

In one form of the invention each type-bar is provided with an upwardly and forwardly extending arm or toe 38, to which one end of a link 39 is pivotally connected, as by a rivet at 40. The rear end of said link 39 is pivotally connected to the upper end of a corresponding lever 41, as by a rivet at 42, and each lever 41 is pivotally attached to a corresponding key-lever 7 in rear of the vertical plane through the pivot-rod 35 of the typebars, as by a rivet'at 43, and each lever 41 is extended downwardly and forwardly beyond its corresponding lever 7 and is provided with an open-ended substantially horizontally extending slot 44, by means of which the lever 41 engages both sides of a horizontal rod 45,

which is supported or secured in frame 1 and v which forms an abutment for operating the levers 41. positively in each direction, thus avoiding the use of separate returningsprings. The shaft 45 may be provided with a series of sleeves 45 loose thereon, one for each lever 41 and engaging the slot thereof for the purpose of reducing the friction. The slots 44 open forwardly of the machine, and the slots 8, 36, and 44, together with the rods 35 and 9,'provide means whereby each individual type-barand its link and actuatinglevers may be removed from the machine and may be replaced without disturbing any other type-bar or type-action, as by turning the bar 9 to bring its flattened sides horizontal, then lifting the desired or selected type-bar 33 vertically from its normal position to disengage it from its fulcrum-rod 35, then pushing the key-lever rearwardly of the machine to dis engage the lever 41 from the rod 45, and then pulling the key-lever forward again until it is disengaged from the rod 9.

The bent or bell-crank levers 41 are of varying lengths, increasing in length from the central line of the machine in each direction toward the sides in order to keep the pivotal points 42 in the same relation to the horizontal planes through the corresponding pivotal points 40, as indicated in Fig. 3; but equal depressions of the keys 10 may be secured byvarying the points of attachment 43 of the levers 41 to the levers 7, thus also producing equal rearward motion of the points 42 as the associated type-bars are thrown to the printing-point, the pivots 43 being moved rearwardly proportionately as the levers 41 increase in length between the points 42 and 43. The pivots 42 are all horizontal, while the pivots 4O become more and more angular to the horizontal as their distance from the central part of the segment 22 increases, but

be reversed by arranging the toe or crank- 4 arm of the type-bar below the pivot and connecting the bentlever to the key-lever and abutment, as shown at Fig. 10. The link and bent lever may also be connected to the type-bar and key-lever, as shown at Fig. 11,

if desiredthat is, with the bent lever connected to the key-lever in front of the plane of the type-bar segment.

; Theoperation of the type action shown in the main views is as follows: Upon the depression of a key 10 and its lever 7 the corresponding lever 41 is pressed against the abutment rod or shaft 45 and begins to slide or move transversely of the same forwardly of the machine, thus causing the lever 41 to turn upon its pivot 43 and draw the upper end 42 rearwardly of the machine. The corresponding. link 39 is drawn rearwardly of the machine, thus pulling upon its associated type-bar at a point above its pivot and rotating the type-bar about the fulcrum-rod 35 and bringing a type upon the bar into con: tact with the paper on the platen 6 at the front side thereof. Upon the release of the depressed key its spring 16 restores the keylever to its normal position and the force of said spring, combined with the weight of the type-bar, causes the barand lever 41 to return to normal position, the rod 45 assisting in the operation and the sleeve on the rod reducing the friction as the lever 41 moves transversely of the rod or shaft 45.

While the type-bars are shown as lying normallyin horizontal positions and as swinging upwardly and rearwardly and striking the platen in substantially a horizontal plane through the axis thereof, it is to be understood that in so far as visible writing is concerned the type may strike the platen at any point of the platen in view of the operator, and that in case the type-bars strike the platen above the horizontal plane through the axis thereof and it is desired to have the type-bars move through not more than an angle of ninety degrees, which is the angle through which the type-bars shown in the drawings move, the plane of the pivots of the type-bars may be inclined to the vertical to the proper degree and may also be moved forwardly, and that in such case the typebars would no longer lie horizontally but would form an angle with the horizontal.

An examination of Fig. 8 will show that the tendency of the pull of the link 39 upon the arm 38 of the type-bar is to prevent disengagement of the type-bar from its fulcrumrod 35, although in the normal position of the type-bar the open-ended slot 36 is in position for disengagement from the fulcrum-rod 35.

The particular construction of the typebars illustrated in the drawings will next be described, with the premise that a fixed guide 46, adjacent the printing-point, is employed in the preferred form of the invention. The guide 46 is in the shape of a V-notch in a metal plate or arm 47, secured to the table 3, as by screws 48, the bottom of the V being extended with parallel sides, as illustrated in Fig. 1, to receive the flat type-bars. Each type-bar in the machine shown inthe drawings is provided with two types 49 and 50, the type 49 representing the lower-case and other characters and the type 50 representing the upper-case or capital letters and other characters. Inasmuch as the type-ring 22 is liftable or shifted upwardly for upper-case work and as the guide 416 is shown as stationary, it results that different portions of each typebar coact with the guide according as uppercase or lower-case work is being done. For the foregoing reason the type-bars 33 are most of them bent at 52 in order to bring a sufficient length of the type-carrying end into the vertical plane when each bar is at the printing-point, (see Fig. 4,) said bends 52 bein g at such a distance from the type-bearing end of the bars as will provide for the shifting action aforesaid without bringing the bends themselves into the guide 46. The bends on one side of the central vertical longitudinal plane through the printing-point are in one direction, as illustrated at Fig. 6, and those at the other side of said plane are in the opposite direction. If the type-guide be mounted to shift with the segment, the bent type-carrying end of the bar may be shorter than shown. As will be understood from an examination of the type-bar shown in printing position at Fig. 4, the type-bar hubs, as well as the slots in which they are placed, radiate to a point above the bend 52, (preferably the printing-point,) and the bars are bent inwardly at points 51 near the hubs,

so that when a bar is in printing position the body thereof extends in a radial direction from the bend 52 to the bend 51, and at an angle to the hub portion thereof, in order to enable a short length of the free end of the type-bar to stand vertically. It is understood, of course, that. if no central guide 46 be employed the bends 51 52 may be omitted that is, the type-bar may be straight and the type-block be set at the proper angle thereto in order to secure the correct impressions from its type.

The type-blocks L9 may be secured to the bar in any known or suitable way. The typebars in their normal positions rest against a padded segment 53, which is rigidly connected with the segment 22 by arms 54 and shifts therewith.

Mechanism for shifting the segments 22 and 53 and the typebars vertically will next be described. A transverse shaft 55 is pivotally connected with the base-frame l, as by adjustable pivot-screws 56, at a distance below the key-levers 7 such that it will not interfere with the operation thereof, said shaft 55 being placed forwardly of the vertical plane of the ring or segment 22. The shaft 55 is provided with rearwardly -extending arms 57, which terminate in or substantially in the vertical plane of the segment 22 and substantially underneath the lines of guidance of the type-carrying segment by the plates 18. Each arm 57 is pivotally connected with a link 58, and the upper ends of the links 53 are pivotally connected with downward extensions of the plates 23, as by pivot-screws 59. The rock-shaft 55 is also provided at near one end, as the left-hand end, with a forwardlyextending arm 60, and said arm is provided with a transverse pin 61, projecting laterally on each side thereof. An upper-case shiftlever 62 is connected with the shaft 11 in the same manner as are the key-levers 7 and is held up by a spring 63, connected with the cross-bar 17 of the base-frame. The lever 62 extends over the pin 61 at one side of the lever 60 and is provided with a finger-piece 64 in the keyboard of the machine. The depression of the key-lever 62 depresses the free end of the lever 6O through the medium of the pin 61 and so rocks the shaft 55 and causes the arms 57 to raise the links 58, and the links push up the segment 22 until the stops 32 strike against the under side of the arms 27 and arrest the upward motion of the segment and the downward motion of key 62. The arms 57 are of equal lengths, thus moving the ends of the segment 22 equally, and the stops 31 and 32 are so adjusted relatively to the arms 27 as that the vertical motion of the type-segment is exactly equal to the distance between the bottom lines of the faces of the type 49 and 50, thus securing the printing of upper and lower case letters in exact alinement with each other. Upon the release of the key-lever 62 the parts are returned to IIO normal position through the action of gravity, the friction being reduced by the ballbearings above described.

The weight of the type-segment and of the parts carried thereby may be counterbalanced nearly, as by the force of springs 65, loosely coiled about the ends of the shaft 55 and each having one end hooking under the levers 57, as indicated in Fig. 2, and the other end engaging under a pin 66, projecting inwardly from the base-plate 1.

In order to start the segment 22 downwardly quickly upon the release of the shift-key, the following devices are provided: Each plate 18 is provided with a screw-stud 67 on the forward side thereof, and about each stud is loosely coiled a spring 68, whose free ends hear one against the under side of the adjacent arm 27 and the other against a stop 69 on the adjacent plate 18 and extends partly across the adjacent plate 23, as indicated in Fig. 4. I Each plate 23 is provided with a pin 70, projecting forwardly therefrom and at a distance below the free end of the adjacent spring 68. Upon the depression of a shiftkey the segment 22 is carried 'upward until arrested by thestops 32 and the arms 27, as aforesaid; but before the stops 32 strike the arms the pins 70 strike the springs 68 and carry them on or upward until the segment is arrested, as aforesaid, thus carrying the springs away from their stop-pins 69 and putting them under greater tension. Upon the release of the depressed shift-key the springs 68 simultaneously act to start the segment 22 downwardly and continue to act until they are arrested by their pins 69. Thus it will be seen that by the use of the counterbalancing-spring 65 the weight to be lifted upon the depression of a shift-key is reduced to a minimum, and that by the use of the springs 68, arranged as described, the segment is instantly started downward upon the release of the depressed shift-key, and that the resistance of the springs 68 to the upward movement of the segment. does not begin until after the segment is Well started upward by v the force exerted in depressing the shift-key lever. The springs 68 may, however, be used without the counterbalancing-springs.

In order to lock the type-segment in its shifted or upper-case position, a second shiftkey lever 71 is fulcrumed on the rod 11 and extends forwardly of the machine at the side of the lever opposite that on which the lever 62 passes and overlies the other end of the pin 61 and is provided with a finger-piece 72. A spring 73, connected with the bar 17 aforesaid, normally holds the lever 71 in its elevated position. The shaft 55 is provided with a vertical arm 74, which is rabbeted or notched at its upper rear corner 75. A latch 76 is pivotally connected to the base-frame 1, as by screw 77, and is provided with a laterally-extending pin 78, which overlies the lever 71, and the parts are so arranged that the free end of the latch 76 is held above and clear of the arm 74 by the key-lever 71, as illustrated in Fig. 9, and as long as the keylever 71 is in its normal or elevated position; but a downward movement of the lever releases the latch, so that it may engage the arm 74. Upon the depression of the keylever 71 the arm 60, shaft,55, arms 57, links 58, and segment 22 are operated to move the segment upwardly until the stops 82 comein con tact with the arms 27, and simultaneously the latch 76 drops down into the position illustrated in Fig. 8, in which the end of the latch 76 abuts against one side of the rabbet and prevents the springs 65 and 68 (or the weight of the parts in case the springs be not used) from returning the segment 22 to a normal or lower-case position, the tension of the spring 73, acting through the lever 71 and pin 78, not being sufficient to overcome the friction or pressure between the end of the lat-ch 76 and the notched end of the arm 74. Upon depressing the shift-key 62 sufficiently, however, the arm 60 and shaft 55 and arm 74 are rocked forwardly slightly, relieving the pressure between arm 74 and latch 76, whereupon the spring 73 restores the lever 71 and latch 76 to their normal po sitions, since the slight forward motion of the arm 74 releases the latch 76, and on releasing key-lever 62 the parts are returned to normal positions by springs 65 and 68. In this way by depressing the key-lever 71 the shifting mechanism may be locked in its upper-case position and the type mechanism be manipulated to print u pper-case letters and other characters continuously by the use of both hands and the type mechanism be released and be returned toits normal position by a stroke upon the key-lever 62.

79 indicates a spacing key or bar lying in front of the key-levers-7, the spacing-bar 79 being carried by levers 80, one at each side of the key-levers 7, and fulcrumed upon the same rod 11 and upheld by springs 16.

81 indicates a vertical projecting plate just forwardof the type-blocks upon the levers 33, said plate being attached to the front standards 2, as by screws 82.

As illustrated in Fig. 7, the pivot 40, between the link 39 and the arm 38 of the typebar 33, is'in the normal position of the parts below the horizontal line or plane through the pivot 42 of pivotal connection between the link 39 and the lever 41. The dotted positions of the parts in said figureindicate the upper-case position thereof, and it will be observed that the new position of the pivot 40 is substantially as much above the horizontal planezthrough the pivot 42 as the normal position of the pivot 40 is below such plane. Since the pivot 40 must move substantially in a right line with the segment 22 and since the link 39 must pivot or swing about the point 42, it results that in shifting the type mechanism up and down the levers 41 may have a slight rearward motion; but owing to the necessary looseness ot' the pivots 42 43 IIO and the looseness at the rod 45 this very slight motion will not offer material resistance to the up-and-down motion of thetype-segment, and the finger-pieces of the key-levers 7 will not be moved from normal position while the type-segment is in its upper-case position. Thus owing to the link and bent-lever connections between the type-bars and the keylevers the vertical shifting, of the type-bar carrier and type-bars is permitted without disturbance of the positions of the key-levers, which is a great desideratum. In other words, the key-levers remain in the same positions whether the type-bars be in their shifted positions or in their normal or lowercase positions. Hence the stroke of a key or depth of depression is uniform in both cases, something not easily obtainable in this type of machine and which is secured in consequence of the link-and-lever connections and their peculiararrangement. When the typebar is in its normal or lower-case position, the links incline slightly upwardly toward the rear of the machine, and when the typebars are in their abnormal or upper-case position the links incline slightly upwardly toward the front of the machine.

While in the preferred form of the invention the levers 41 are straight and occupy a width of the machine at their points of attachment to the key-levers equal or substantially equal to the chord of the arc in which the type-bars are pivoted, it is understood, of course, that the invention is not wholly limited to such arrangement and to such straight bent levers 41, and consequently is not wholly limited to key-levers 7, bent as described or even having any lateral bends at all.

In the preferred form of the invention, or that illustrated in the drawings,the key-levers 7 at the general location where the levers 41 are fulcrumed thereon haveacollective width transversely of the machine slightly less than the chord of the arc in which the type-bars are pivoted, and the chord of the arc in which the upper ends of the levers 41 are arranged is substantially the same as the said collective width. This slight inequality between the collective width of the key-levers and the chord of the type-bar-pivot are or curve is due to the fact that the levers 41 are connected with the type-bars at points above the pivots of the latter, and it is obvious that in case the said connection between the levers 41 and the type-bars were below the pivots of the latter and it were still desired to have the type-bars by pivots which are parallel to the pivot of the type-bar in each individual case.

In the modification shown in Fig. 11 the form of the bent lever is different from that in the preceding views, and itis pivotallyattached to the key-lever at a lower point, the key-lever being provided with a downwardlyextending ear for this purpose.

In the modification shown in Fig. 12 the lower end of the bent lever is not provided with a slot, as in the previous views, but is pivotally connected to an abutment in the form of a link 45, that is pi totally supported at its lower end at 45. This link will effect a vibration of the bent lever upon a depression of the key-lever in substantially the same manner as the pin-and-slot connections in the other views.

While I prefer to make the type-action or type-movement complete as a whole before assemblage in the machine, this feature of course is not essential to the proper operation of the mechanism. and if the same be not desired the joints may be detachable instead of riveted, as shown.

It will be observed that the bell-levers 41, each of which extends to a point above the pivot of its type-bar, are pivoted at their lower rear portions upon a series of converging key-levers which extend rearwardly beneath the type-bar system and that a tulcrum is provided for the lower front portions of said bell-levers, each of the latter being pivoted at a point between its ends to the key-lever, and one end of the bell-lever extending downwardly and the other upwardly from said pivot, and the key-lever being disposed or lying between the abutment 45 and the link 39. At the shifting operation all of the links 39 vibrate simultaneouslyin substan tially-vertical planes about the pivots 42, the movements of the forward ends of the links and of the sliding type-bar segment being first away from and then toward the key-levers. The pivots 42 are arranged substantially at right angles to the direction of the shifting movement of the type-bars, each of said pivots being arranged transversely of the machine and the shifting movement being in an up-and-down direction. Each lever 41 moves in a direction at an angle to the direction of movement of its key-lever, the movement of said lever 41 being fore and aft and that of the key-l ver being up and down. The link 39 extends substantially in the direction of movement of the bell-lever 41. Preferably the typebars the links 39, and the levers 41 are of thin construction to economize room and reduce inertia.

The type-action may be used in a machine wherein the chord of the type-bar segment or support is equal or substantially equal to the width of the key-board, and the type action may also be used in a machine wherein the platen is shifted instead of the segment and type-bars. Moreover, the type-action may be'used in a machine in which neither the platen nor the segment shifts and in which each type-bar is provided with only one type. Again, the type-bar proper may be of different form or constructionthat is, it may be a jointed or compound; type-bar adapted to an inking-pad. The type-bars herein shown are adapted for use inconnection with inkingribbons in the usual way.

Various other changes in detail construction and arrangement may be made without departing from the gist of my several improvements as set forth in the following claims.
