FLORIAN J. MARTIN, OF MILWAUKEE, WISCONSIN.

SPECIFICATION forming part of Letters Patent No. 708,570, dated September 9, 1902.

,Application filed April 18, 1901. Serial No. 56,450. (No model.)

To all whom, it' may concern:

Be itknown that I, FLORIAN J. MARTIN, a citizen of the United States, residing at Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented a new and useful Printing-Machine, of which the following is a specification.

This invention relates to printing-machines, and more particularly to a machine to be used for numbering and price-marking and for protection in the issuing of checks, drafts, duc. i

The object of the invention is to present a simplyconstructed, thoroughlyreliable, cheap, and durable machine for the purpose named in which the parts shall be so combined and operated as to reduce to a minimum any danger of breakage or derangement in use and which may be quickly and readily employed either for printing lengthwise of a strip of paper, as with checks, drafts, tbc., or crosswise of such strip, as in price-marking, numbering, ttc;

With the above and other objects, herein- Vafter more fully explained, in view, the invention may be said to consist generallyin a casing in which are housed apluralityof typewheels, combined with type-wheel actuators and indicators, the latter being composed each of two oppositely-disposed sectors concentric with each other, one of which sectors is provided with teeth meshing with gearwheels carried by the printingwheels and the other with characters corresponding with those on the type-wheels. rIhe type-wheel actuators and indicators move through an arc concentric with that traversed by the type-wheels, so that when a character on the outer sector, which constitutes the indicator, is brought opposite a suitable pointer the operator will know that the corresponding character on the type-wheel is iu position to be broughtinto contact with the platen, thereby to effect printing.

The invention consists, furthermore, in

combining with the bed-block, the latter supporting an inking-pad, a combined platenshifting bed-block and inking-pad-actuating lever, the three functions performed by this lever being accomplished in regular successive order of operation-that is to say, movement of thc lever in a horizontal plane in one direction operating to remove the platen from over the inking-pad and downward movement of the lever while in this position operating to elevate the bed-block, thereby to bring the inking-pad into engagement with the types of the printing-wheel, and Inovement of the lever in an opposite direction in a horizontal plane serving to bring the platen over theinkiug-pad, and downward movement of the lever whilein this position operating to move the platen toward the typewheels, thereby effecting an impression on a strip of paper interposed between the typewheels and the platen.

Further and more specific details of construction will be hereinafter more fully described and claimed.

In the accompanying drawings, forming a part of this specification, and in which like numerals of reference indicate corresponding parts, I have illustrated a form of embodiment of my invention capable of carrying my procedure into eifect, it being understood that the invention may be constructed in other ways without departing from the spirit of the same, and in these drawings- Figure lis a view in perspective of a printing-machine embodying my invention. Fig. 2 is a view in vertical transverse section. Fig. 3 is a longitudinal sectional view taken on the line 3 3 of Fig. 2 looking in the direction of the arrow thereon. Fig. 4 is a view in sectional plan taken on the line 4 4E of Fig. 2 looking in the direction of the arrow thereon. Fig. 5 is a detached detail View in elevation of one of the printing-wheels, showing more particularly the mechanism by which the type is held over the platen against shifting movement when printing is being done. Fig. o' is a perspective detail view of a portion of the combined platen-shifting bedblock and inking-pad-actuating lever.

Referring to the drawings, l designates the casing of the machine, comprising two end plates 2 and a cover or shell 3, connecting the end plates and serving to house the internal mechanism of the machine. The end plates may be made of any suitable material, preferably of metal, and formed in .any desired shape in elevation, and are secured to a base et in this instance by screws .5, passing through flanges G on the end plates. Ex-

IOC

tending longitudinally of the casing and working in suitable journal-bearings in the end plates is a shaft 7, carrying the typewheels 8, of which there are shown in this instance seven, although it is to be understood that this number may be increased or diminished without departing from the spirit of the invention. As each of the type-wheels of the series is a counterpart of the other a description of one will serve for all. these wheels carries on one side a gear-Wheel 9, which may be integral with the wheel or be secured thereto, and on the opposite side a ratchet-wheel 10, which may be either integral with or secured to the wheel, the ratchetwheel being provided with depressions or V- shaped incuts 11, corresponding in number to the type carried by the face of the wheel, thesedepressions to be engaged by a tooth 12, carried by a spring-rod 13, mounted on a shaft 14, secured in the end plates.

Mounted in parallelism with the shaft 7 is a shaft 15, this shaft, as shown in Figs. 1 and 2, being disposed toward the front of the machine and journaled in bearings 16, carried by the end plates 2. Upon this shaft is mounted aseries of type-wheel actuators and indicators 17, each being the counterpart of the other, so that a description of one will serve for all. Each type-wheel actuator and indicator is composed of two oppositely-disposed sectors 18 and 19, respectively, the sector 18 being provided on its periphery with teeth to engage the gear-wheel 9 of the type- Wheel and the other sector carrying on its periphery characters corresponding to those on the type-wheels. The sector 18 is here shown as a solid structure and the sector 19 as a hollow or open-work structure, this latter arrangement being adopted for purpose of lightness; but it is to be understood that, if desired, both of the sectors may be solid structures or both may be open-work. The periphery of the sector 19 is divided into twelve spaces, corresponding to the number of type carried by the type-wheel, the center space of the sector being occupied in this instance by 0 and the succeeding spaces but one toward the front of the machine by numerals, arranged in this instance in the following order: 5 1 2 3 4, the lowest space being occupied by a character, in this instance a cent-mark. This corresponding space in the next sector is provided with a per-cent. mark, the next three succeeding spaces by stars, and the next two succeeding spaces by dollar-marks. From the 0 toward the rear of the machine the spaces or the sector have figures arranged on them in the following order: 6 7 8 9, the last space being blank throughout the series, so that any number containing from one to six figures may be printed. The sector at the left hand of the machine is by preference devoted to characters-such as a dollarmark, the English pounds-mark, the abbreviation No., the conventional representation of a number, in-

Each of dicated by four crossed lines, the letter A, the letter 13, the letter C, the letter D, the letter 12, the letter F, and the letter G, or these letters may be dispensed with and other characters used in trade employed in lieu thereof. By having the O arranged in the center space of each sector it will be only necessary to rotate the sector through the arc of about one-eighth of a circle to bring one-half of the characters on the type-wheels in position to print and like movement of the sector in the reverse direction to bring the remaining characters of the type-wheels in position to print. To facilitate manipulating the sectors, each is provided at its opposite ends with a knob or projection 2O to be grasped by the fingers of the operator. In order that the toothed sector shall be kept in positive mesh with the driving-gear of the type-wheel, so that when the sector is moved through the limit of its arc in both directions there will be no danger of the toothed sector and driving-gear becoming unmeshed, two stop-rods 21 and 22 are employed, these eX- tending longitudinally of the length of the casing and are engaged by the ends 23 of the sector 19, which, as shown in this instance, are squared or flattened for the purpose.

To afford visual means of determining when the proper type on the type-wheel is over the platen or printing-point, two pointers 24 are employed, one at each end of the casing, these pointers being toindicate what character on the type-wheel is in striking position. Thus when the sectors are moved to bring any character or aggroupment of characters or any number or aggroupment of numbers on the type-wheels in position to impart an impression the characters or numbers must all aline with the two pointers, and when this is effected there will be no possibility of a mistake occuring in the printing. By reason of the coaction between the tooth 12 of the locking-spring and the ratchetwheel 10 any number of impressions may be taken from the characters or numbers that have been brought under the platen. This arrangement distinguishes this device somewhat from other machines of this character wherein upon the taking of each impression the type are shifted.

Arranged under the type-wheel is a bedblock 24a, the same being constructed of any suitable material, preferably of wood, and provided near each end with an orifice 25, in each of which works a headed pin 26, a coiled spring 27, interposed between the head of each pin and the bottom of the orifice, serving normally to hold the base-block depressed, and thus the platen away from the typewheels. Secured upon the bed-block 24 are two guides 28, each provided with two guideways 29 and 30, respectively, the guideways 29 being formed by inwardly projecting flanges either secured to orintegral with the guides and the guideways 30 by the under sides of the lower flanges and the upper sido IOO IIO

of the bed-block. The guideways 30 are engaged by an inking-pad carrier 31, the same comprising a sheet of metal provided with a rectangular opening in which sits the inkingpad 32, the object of this arrangement being to permit ready removal of the inking-pad when the same is to be reinked. The upper gnideways 29 are engaged by the platen 33, this platen when printing is to be effected being moved over the inking-pad to the position shown in full lines in Fig. 4 and when the inking of the type is to be effected to be moved to the position shown in dotted lines in Fig. 4.

The mechanism for effecting raising and lowering of the bed-block, and with it the platen, and the shifting of the platen to and from the inking-pad comprises what l term a combined platen-shifting, bed-block, and inking-pad-actuating lever 34. The leveris fnlcrn med on a pin 35, extending upward from a rock-shaft 36, the rock-shaft having at one end an arm or projection 37, bearing against the under side of the bed-block, as clearly shown in Fig. 3, the opposite end of the bedblock being raised by an arm 3S, forming a coactive part of the lever above referred to. The arm 38 is secured to t-he shaft 36, as clearly shown in Fig. 2, and carries on its outer end or that disposed toward the front of the machine a attened or enlarged head 39, the under side of which carries a depending pin 40, working in an orifice 4l, formed in the base, a spring 42, coiled upon the pin 40 and bearing against the under side of the head and lthe upper side of the base, serving to keep the arm normally depressed. The arm 38 is provided on its upper surface with an overhanging lug 43, engaged by` an enlarged flattened head 44 of the lever 34, by which arrangement, as will hereinafter appear, the lever 44 may be swung through the arc of a prescribed circle and still be kept in engagement with the lug 43. The lever 34 carries an arm 45, extending approximately at right angles to the length of the lever and curved upward, as shown in Figs. l and 2, and carries at its free end a pin 46, working in a slot 47, formed in a tongue 48 of the platen 33, the shaft 36' being provided with two pins or projections 49, one on each side of the tongue, to guide the same in a right line.

Where nu mbers or characters are to be placed lengthwise of a strip of paper, as with checks or the like, it will be obvious that the strip will have to be fed in a direction parallel with the lines of type on the type-wheel, and where the characters are to be crosswise of the strip of paper, as in price-marking, numbering, and the like, it is obvious that the strip of paper will have fo be fed at right angles to the lines of type on the type-wheel. To permit the feeding of the strip of paper lengthwise of the lines of type, each end plate of the casing is provided with a slot or opening 50, arranged in line with the platen 34, so that the strip of paper may he readily positioned for receiving an imprint.

When, however, the impression is to be crosswise of the strip, the feeding takes place from the front of the machine, and in order to guide the strip of paper to position and also to keep it out of contact with the inked type guides 5l are employed, these being formed, preferably, as shown in Fig. 2, by bending in a portion of the lower end of the cover or shell to the position shown in Fig. 2, the portion bent in to form these guides being that which would ordinarily be cut off to permit operation of the lever 34 and the other parts of the device. It is to be understood, however, that I do not limit myself to the exact arrangement of paperguides shown, as others maybe employed, operating in substantially the same manner, without departing from the spirit of my invention. It will here be noted that the feedopenings 50 are alined transversely of the front and rear feed-openings formed by the space included between the base and the guide-plates 51, whereby the machine is provided with two work-guides, which are disposed at substantially right angles to each other in order that a check or the like may be fed to the printing means from the front, back, or either side of the machine, according to the required disposition of the characters upon the check.

When printing is to be eected, the following procedure is to be observed: Suppose it to be desired to print upon a strip of paper, say, for example, $450. The sector at the lefthand of the machine will first be rotated toward the rear of the machine to bring the dollar-mark opposite the pointer 24, then the next sector is moved to bring the 4l opposite the pointer, the next sector to bring the 5, and the next sector to bring the 0. The remaining sectors will be then moved either to bring the blank spaces thereon opposite the pointers or other characters after the 450, such as stars or the like. As each of the sectors is moved like movement is transmitted, through the sector 18 and the driving-gear 7, to the corresponding typewheel, and the type corresponding to that on the sector 19 is brought in position over the platen to print. The machine being thus set, the lever 31 is moved to the right to clear the inking-pad 32 of the platen 34, and the lever is then depressed to lift the bed-block and cause the inking-pad to contact with the type.

When the lever is released, it will automatany other material to suit the purpose, or, if

l preferred, they may be a part of the typewheel-in other words, cut thereon. of rubber or any material other than metal, they will be cemented to the faces of the typewheel in the usual manner, or they may be secured thereto by screws. Where on metal and when not an integral part of the wheels, they1 may be secured in position by being dovetailed to the faces of the wheel or be secured thereto by screws or other fastening means.

It will be seen from the foregoing description that while the device described provides for every contingency that will arise in the employment of a printing-machine used for the purposes designated that it is composed of a very few number of parts and that these are so assembled as to present the highest and most effective range of usefulness with the slightest possible danger of derangement or breakage in use. All of the parts may be made interchangeable, so that in event of the breakage of one or more parts these may be supplied from the factory and positioned in the machine by a person of ordinary ability.
