tion of the various parts separately.

Be it known that I, HENRY BAB'rn, of the city of Cincinnati, in the county of Hamilton and State of Ohio, have invented a certain new and useful Improvement in Stop-Cylinder Printing-Presses, of which the following is a specification My invention relates to mechanism for stopping and starting the cylinder of a stop-cylinder press, whose circumference is greater than the way described by the bed-plate; for conof the type; and 0, Fig. 4, theimpressioncylinder. The feed-board F is provided with purpose of receiving a motion on and 0d the discharging it therefrom; for distributing the ink; and for other purposes, as will more perfectly appear in the description hereto annexed.

In the drawing, Figure 1 represents a side elevation of the whole press. Fig. 2 is a longitudinal section, looking toward the side frame S. It is intended to show the stop and starting mechanism, the ink-fountain, the motion of the dip-roller, and the motion of the ink-fountain roller. For the purpose of being bed B. The type-bedB runs on rollers fitted der side of the bed B, and which is driven by rack D, Fig. 1,which 18 secured tothe groundtop view of one corner of the press. It shows the position of the different cams on the main shaft. Fig. 4 is a part of a longitudinal section through the center line of the press, on a larger scale. It represents the complete cylinder with all its details, he feed-board, ers, and the paper-discharge arrangement. Fig. 5 is a complete cross-section of the press,

I.--The Motion of the Type Bed and Cylinder. F, Fig. 1, is the feed-board B, the bed trunnions, which rest in bearings placed on F j l the vibrating arms A, A. A, and A, for the impression-cylinder, in a manner hereinafter described. The impression-cylinder is held in; i bearings which are fitted to the side frames f i 1 S and S, Figs. 1 and 5, and. is operated at Fig. 4, which driven by the rack B, fastened to the type-g to the ribs X X, Figf5,and is operated by the rack Z, Fig. 4, which is bolted to the unthe traveling wheelT. The traveling wheel T gears at the same time into the stationary frame F. By means of the rod Y, Fig. 1,.the axis of the wheel T is connected with'the .9

and is driven by the pinion The pinion P v is keyed to the shaft K, to which the motive 1 power is applied. u Thedriving-shaft K has. i to be turned in direction of the arrow,and the pinion P fixed to it will drive the. wheel I v of the crank, which is formed by inserting-the motion of wheel I will cause an alternative T.

As far as the description now reaches, the motion of the bed B and of the impressioncylinder 0 of the press does not differ from L, the one end of the connecting-rod N, Fig.2, is attached by means of the wrist-pin g. The other end of the connecting-rod N is held by the hanger 0 through the pin it. The hanger O oscillates upon the pin 2 attached to the frame.

part of my invention consi ts.

The drawing shows all the different parts of my press in the positions they have at that moment when the type-bed B commences to that the straight line, which bisects the sinus versus of the angle of vibration of the lower arm of the lever L, and which passes through the axis of the main shaft J, bisectsthesinns versus of the angle of vibration of the hanger 0 also. To the connecting rod N the two friction-rollers k and l are attached. The cam Q acts upon the roller k, and the cam U upon the roller 1, Fig. 2. The cams are firmly secured to the shaft J, so as to rotate with the same; they have such a shape and their position is so adjusted as, through the medium of the connecting rod N, the double lever L, and the teeth f e and e, to start and stop the cylinder 0,

0 cl have changed their positions, the cylinder is stopped bya mechanism hereafter described and is held at rest when the type-bed B is about to make its return movement. As soon as the bed B commences a new stroke in the direction of the arrow the cylinder 0 is started and turns with the bed again, but another part ofthe cylinder namely, the surface a b cylinder are in the position in which they are drawn, and the bed is going to move in the direction indicated by the arrow, the cylinder is started by the cams and caused to turn in .snaeiasthet ne-hedntatiT ot gear into so as to print, successively, three, four, or more sheets of the full capacity of the type-bed during one revolution of the cylinder, and while they are entirely in gear when the tooth 0 leaves the space f then the rackR continues to drive the cylinder, and the lever L, with the space f, is caused by the cams to move backward to the extreme position f 9, Fig. Fig. 2, on the ends of the connecting-rod N, At the same time the cylinder (J has arrest the shock caused by the tooth e in the cylinder striking against the tooth fin the lever L.

II. 'Thc rllechanr'srn for Stopping and Starting the Cylinder.

v For the purpose ofstopping and starting the impression-cylinder twice, or oftener, during one revolution, the cylinder is provided out of gear. When the double-armed lever-L arrives at its mean position, eg, the cams will cause the same to. stop there and to hold the cylinder stationary. A little time after the cylinder is stopped, the type-bed B has finished its forward stroke, and while it'is running back, the cylinder 0 is caused, bythe cams, to remain stationary, and as the teeth are-cut ing-surfaces and two stops, the impressioniylinder O is provlded with the two stoppingmd-starting teeth 6 and c, Fig. 4. They are lot attacheddirectly to the cylinder, but they re firmly secured to the spur-wheel W, Fig. which is fastened to the cylinder 0. One fter the other the teeth 6 and e gear into the as follows: At the moment when the'bed and I cylinder will be analogous to aw y at the part of the wheel \Vwhich faces the rack B, while the cylinder is held stationary the bed B can freely pass under the cylinder. When the bed B has arrived at its extreme backward position, from where I started to follow its motion, and in which position it is drawn, the double armed lever L is in its startingrposition also, but the cylinder 0 I find one-half turned around, and the teeth 0 e and the printing-surfaces a b and 0 d in changed places. But as the two halves of the cylinder are symmetrical, the position of the the position in which it is drawn. While the bed is running forward and backward the next time, the cams and U will start and operate upon the second half of the cylinder 0 in the same manner as during the first forward and backward strokes of the bed. My stop-and-start mechanism has the advantage over many others designed before, of having less joints, and the relative positions of the double lever L and the hanger O, as described above, cause it to operate with perfect accuracy. For the purpose of observing conveniently the action of the stop-and-start teeth f e and e, I have provided the side frame S with an opening or window, V, Figs. 1 and 4, which assists me in adjusting these important parts very finely and perfectly.

III.-T he Paper Feeding and Delivery Arrangemeat.

The arms A A A and A, Figs. 1 and 2, upon which the feed-board F rests, vibrate on pins inserted in the side frames S and S. The arm A is made with the arms at and n, Fig. 1, in one piece. Over the end of the arm at a projection of the side frame S is provided, with an adjusting screw, as, Fig.1, by which the end position of the feed-board F, in regard to the impression-cylinder U, can be regulated. A double armed or elbow lever, s, Fig. 1, is fastened inside of the side frame S to the. shaft or axle t; A hole bored through the side frame S serves as bearin g for the shaft t. The shorter arm 1" of the elbow-lever s and the arm n of the threearmed lever A m n are connected by the rod upon which a spring is wound. One end of this spring presses against the guide q through which the rod p goes, and which is fastened to the side frame S '5 the other end of the spring acts upon the head 0 of the rod 1),- consequently the spring will push the feed boardF so far toward the impression-cylinder U as the setscrew as over the arm will allow. To the longer arm 98 of the lever-elbow s the cam-rod c islattached. At its lower end the cam-rod v is provided with a long. hole, in which it is guided by shaft 2 in one way, while between the collar-y and the cam w,it is guided the other way. The cam w is fastened to thecam-shaft z, and acts upon the roller 2). It has such a shape, and. such a position, that itqcauses,

through the roller 1:, the cam-rode, the elbow-;

levers s, the rod 1), and A, the feedboardF to move, at correct times, off of the impression-cylinder 0, holds it in the position furthest from the cylinder, while the paper is put onto it, and moves it upto the cylinder again, bynieans of spring 12, a little before the cylinder is started. I The cam-shaft z receives a rotary motion from the continuation z of the main shaft, J, through the miter wheels 16 and 17, Fig. 1. The continuation e, which lies in line with the main shaft J, is provided with the crank 18, I by 3 Y which it is coupled by means of the connecting;

piece 100 to H of on the main shaft wrist pin the wheel I,

and its continuation z.

inder, and gears into secured to the pulley-shaft 3. The shaft 3 is held in bearings in the side frames Sand S,

and carries two or more pulleys 4 4, which slide on the shaft 3, and may be tightened at any place required, Figs. 1, 4, and 5. The arms 5 5, which form at each end a fork, are slipped on to the shaft 3 the same time with the pulleys 4 4, so that each of the pulleys 4 4 is situated between the two blades of the fork at one end of one of the arms 5 5, and so that when a pulley 4 is moved on the shaft 3, the arm moves with it, and that when the pulleys 4 4 are tightened to the shaft 3, the shaft can revolve freely in the holes of the arms. In the forks at the other endsof the arms 5 5, the pulleys 6 Gare placed revolvingthe pulleys 4 4 on pins. Over every pair of and 6 6, one of the endless India-rubber belts 7 7 is stretched. The diameters of the wheels 1, the pinion 2,

touch the surface of the impression-cylinder G, and that the speed of the belts 7 7 is just equal to the speed of the circumferenceof the cylinder 0. Figs. 1 and 4, extending from side to side, and fastened to the frames S and S. Upon this bar 8 the polished metal guides 9 9 9 9, Fig. 4, are slipped, andmay be screws at places required.

India-rubber bands 7 j 7, is to be set, so that the rubber=bands, when in motion, slide on the guides. In front of the cylinder 0, and above the same, a basket 10, composed of small metal strips, is placed to serve as an outlay table. Itis soconstructed, as to be lengthened and shortened, and it can be easily taken away and replaced. Inside the cylinder 0 are arranged for eachprinting Under each of the ing the paper. To the shafts13'and 14 the levers 15 15 15 15 are fastened,.one.at each end of each shaft. Two pairsofthe levers 15 15, situated at the same end of .thecylinder,

one of which belongs to shaft:,13',- and*roneiito and through the arms a J, so that the cam-shaft z will make the same turns as the main shaft J, j y 1 At the end of they cylinder 0, opposite thewheel WV, the spur H U wheel 1, Figs. 1 and 5, is fastened to the: cylthe pinion2, which is 1 andturn with it,

and the pulleys 4 4 4 are so calculated, that the India-rubber belts 7 7 Above the cylinder G is bar 8,

tightened by setone of the guides 9 9 shaft 14, are connected by the rods 19 19. To those ends of the connecting-rods 19 19 which The gripershafts 11, and the discharge finger-shafts 13 13 and 14 14, are held-in bearings in the webs of the wheels at either end of cylinder 0. The griper-shafts 11 11 project over their bearings in wheel 1, Figl 1, and are provided outside of Wheel 1 with double-armed levers 22 22, made in one piece with the shafts. To these levers are attached at one arm the friction-roller other arm the spring-rod 24. A spiral spring, wound over each of the rods 24, presses with one end against the guide 25, through which the spring-rod 24 goes, and with. the other end upon the head of the rod 24, and so acts For the purpose of opening the gripers to receive the paper to be printed, and to deliver plane upon which the friction-roller 23 runs, and so the gripers open. The cam 26 is drop by the revolving cam 31, whichis fastened to and revolves with the cam-shaft z, and which acts upon the roller 30 attached to the cam-rod 29 the latter is jointed to the cam 26. The cam 27 is fastened stationary to the side frame S in such a position and with such a shape that the roller 23 will run on to it, and cause the gripers 12 12 12 to open when the end of the paper arrives under the rubber belts 7 7 7, and that the roller 23 will run off and close the gripers again after the paper is'delivered.

The discharge fingershafts 13 13, Fig. 4, project over their bearings in wheel W, and carry outside of this wheel the levers 32 32, fastened to the shafts at one end and provided with a friction-roller, 33 33, at the other As long as. the roller 33 is in contact with the the ends of the fingers 21 21, to the endless India-rubber bands 7 7, and to follow the mo;

tion of the paper, moving with the rubber bands 7 7 until the paper reaches the polished metal guides or ways 9 9 9 9; then the roller 33 will leave the cut-out and the fingers 21 21 will be drawn back to the cylinder. The combination of the shaft 14 with shaft 13 causes the tips of the fingers 2121 to describe such a way that they follow the motion of the India-rubber bands 7 7, or of the edge of the paper which is moving with them. A little irregularity is corrected by the elasticity of the fingers 21 21. Under the cylinder, and attached to the rods 103 and 109, are tapes, or elastic bands 108 108, Fig. 4, to hold the paper to the cylinder smooth and free from Wrinkles.

IV.The Inking Apparatus. The inking consists in the ink-fountain 37,

Fig. 1, with the iron roller 38, the composi-- tion dip-roller 39, the composition table-distributers 40 41 42, the ink-table 43, Fig. 4

the four composition form-rollers 44 44 44 44,

the two ink-cylinders 45 45, made of iron or hard wood, the two composition distributingrollers 46 46, and the small iron rollers 47 47.

In the drawing the dip-roller 39 is shown While the dip-roller 39 is in contact with the roller 38, this is turned so as to receive a thin coat of ink from the reservoir of the ink-fountain, which is 48, Fig. 2, and to which the ink is supplied, and so as to apply a narrow stripe of ink to the dip-roller 39. The thickness of the coat of ink, which the roller 38 takes out of the reser: voir, can be regulated by the set-screws 49 49 49, Fig. 2. Each of these set-screws acts upon one levers 50 50 50 press the knife 48 more or less against the roller 38. The amount of turn of the roller 38, and consequently the width of the stripe of ink put onto the dip roller 39, can be regulated from the feeders stand. When, as the bed B with the ink-table 43 is running forward and backward, the ink-table 43 passes under the dip-roller 39, the latter will drop and roll upon the ink-table 43 and give The distributingrollers and they divide it over the inkunder them.

The form-rollers 44 44 44 44, Fig. 4, take ink from the ink-table 43 while rolling on the same; then give the ink to the ink-cylinders 45 45 and take it back from them in a more equallydivided state; and then apply the evenly-die I reservoir.

pieces of paper, and other strange bodies,

vided ink to the type or form while it'is passin g under them. Upon the ink-cylinders 45 roll and vibrate the distributin g-rollers 46 46, connected with which are the iron-rollers Altogether the system of rollers compiled over the form-rollers distributes and grinds the ink very finely, and serves as a By this arrangement all dust,

mixed accidentally with the ink, will accumulate on the small iron rollers at the top, and

the composition-rollers 46 46 on top of theinkcylinders 45 45 vibrate. By this arrangement all composition-rollers in the system are more durable.

The ink-cylinders 45 45 are held in stationary hearings in the roller-frames 51 52, which are firmly secured to the side-frames S and S; but; the bearin gs are so arranged that the cylinders 45 45 can be easily taken out, when required. Upon the shaft of each ink-cylinder a toothed wheel, 53 53, Fig. 1, is fastened, by which the cylinder is operated. These wheels gear into the intermediate wheels 54 54 which are driven by the rack 55 fastened to the bed B.

Iheiformrollers 44 44 44 44 are held in adjustable bearings 56 56 56 56, so that they can be lowered and moved onto the ink-cylinders 45 45 when they become smaller in size by shrinking or wear and that they can be quickly and correctly adjusted in regard to their position to the ink-table and form and to the ink-cylinders. The form-rollers 44 44 44 44 are turned by friction by the ink-cylinders 45 45. The bearings 56 56 56 are made with round stems, which fit in holes in the bearing-holders 57 57 57 57. ()n the stems of the. bearings 56 are screw-threads cut and the 7 nuts 58 58 screwed, by which either end of the form-rollers-may be raised or lowered. The bearing-holders 57 57 57 57 slide with grooves planed in them on projections 59 59 of the roller-frames 51 52; and they can be tightened by the set-screws 60 60. The nuts of the setscrews 60 60 are tapped into the bars 61 61, which are slipped with their open holes between collars on studs 62 62. The studs 62 62 are riveted into the roller-frames 51 52. Between the bearing-holders 57 57 and the set-screws 60 60 the plates 63 63 63, which slide on the studs 62 62 62, are placed to prevent the points of the set-screws 60 60 60 from being pressed into the roller-holders 57 57 When one end of one roller is to be moved on or off the corresponding set-screw only is to be loosened. When all the form-rollers are to be taken out the set-screws 60 60 of one side have to be loosened and the bar- 61 lifted 06'; then the plates 63 63 and the bearingholders 57 57 with the bearin gs can be slipped off endwise, and the rollers 44 44 may be easily and quickly taken out.

The distributing-rollers 46 46 receive their.

vibrating motions from the eccentrics 64 64 fastened to the cam-shaft z, and through the eccentric yokes and rods 65 65, the double-armed levers 66 66, the connecting-rods 67 67, and single arms 68 68. The eccentric yokes and rods 65 65 are made in one piece, andthey are jointed to the lower arms of the double-armed levers 66 66, which vibrate on the pin 69 of the bracket 7 0. frame S. Each of the connecting-rods 67 67 joints the upper endof the upper arm of one.

of the double levers 66 66 with the upper end of the opposite single arm 68, and causes the same to vibrate on the pin 71 of bracket 72, which is bolted to the side frame S. Between the levers 66 66 and 68 68, and in the slots of.

the roller-frames 5152, the vibrating rollers 46 46 are held. This arrangement isimplifies 1 the laying in of the rollers very much, because no cross-heads or collars have to be attached to them, as in presses which have levers only on one side to vibrate the rollers. uting-rollers 40 and 42 are vibrated from the eccentrics 73 73, which are fastened to the camshaft 2 also, by the double-armed levers 74" y 74 and the single levers 75 75, through similar means and in the same manner as the rollers 46 46. The bearings in whichthe rollers 40 41 i 42 are held are like thebearings of the formrollers, but open on top and only adjust-ablein height. The dip-roller 39 is held in bearings in the vibrating arms 7 6and 77, Fig. 2, which are fastened to the shaft 78. The shaft 7 Sis held in hearings in the side framesS and S. The rod 79 is connected "at one end with the arm 76, and is providedwith the roller .80 at y the other end. Near the end with the roller 80, the rod has a long hole, in which it is guided on the pin 81 which is fixed to the side frame S. The cam 82, which is firmly secured I to the main shaft J, acts upon the roller 80,

and has such ashape and such a position that it causes the dip-roller 39, at right times, to come in contact with the fountain-roller 38, and to leave this to roll on the ink-table43. The ink-fountain roller 38 is caused to turn, when in contact with the dip-roller, by the cam 83, which is firmly secured to the main shaft J, at the end, projecting over the bearing in y The cam 83acts upon the roller i 84, which is attached to the lever 85. The lever 85 is fastened to the shaft 86, outside of i I the side frame S. The rod 87 connects the lever 85 with the inside ratchet-wheel 88, which] is put on the ink-fountain roller 38, and open:

side frame S.

ates the same. The shaft or axle86 is held in a long bearing in the side frame S, and the lever 89 is fastened toit "inside of the side 1 frame S. Through the rod 90, the lever 89 is 1 connected with the lever 91, which is keyed to. the shaft 92 inside of the sideframe S. The shaft 92 is held in a long bearing in the side The bracketTO is bolted to the side V The distribi frame S. Outside of the side frame S the handle-lever 93 is fastened to the shaft 92. From the lever 93 the ink-fountain roller 38 may be turned by hand.

V.--Arrangementfor Double Rolling and Single Printing.

For fine work it is sometimes required to let the bed with the form run twice forward and backward under the ink-roller. For this purpose I have arranged my press with a mechanism which, when in operation, causes the feedboard F, with the paper, to remain in the position off of the cylinder 0, while one set of gripers is about to close, so that these gripers cannot catch'the paper. The second set of gripers will find the feed-board and the paper in the right position to take hold of the paper when they are going to close. In case double rolling is wanted, I provide only one (either one) of the two printing-surfaces of the cylinder G with a blanket, and make only this surface ready for printing; so that the surface not used is about the blanket thickness lower than'the other, and the form can pass freely under it. To prevent the feed-board F from moving toward the cylinder when that set of gripers is going to close which is not to be used, the lever 21, Fig. 1, is fastened to the shaft it outside of the frame S. To the lever u the rod 94 is attached at one end, and the other end is provided with the roller 95, and guided by means of the pin 96, and the cam 97 attached to the projection of the shaft of the cylinder outside the side frame S. When the feed-board moves (311' of the cylinder, the lever u and the rod 94, with the roller 95, move downward; when the feed-board moves to the cylinder, these parts move upward; but that part of the cam 97 which is larger in diameter touches the roller 95 when in its lowest position, and prevents it from moving upward, and consequently the feed board from moving to the cylinder. The cam 97 can be fastened by the screw 99 in such positions that the larger part of the same will be in contact with the roller 95, when those gripers are going to close, which are not wanted to catch the paper.

The smaller part of the cam 97 never touches the roller 95, and is so situated that the roller 95 can freely rise; hence the feed-board with the paper can move toward the cylinder when that set of gripers is going to close which belongs tothe printing-surface in use.

What I claim as my invention, and desire to secure by Letters Patent, -is-' c 1. The hangers O, in combination with the connecting rod N, having on its end the spring 107, and the double-armed lever L ending in the female stop-and-start tooth f, substantially as and for the purpose set forth.

2. The cam u on the'cam-shaft z, in combination with the cam-rod v, the elbow-lever s, the rod 10, arms a and A, and feed-board F, for the purpose set fort 3. The shaft 14, in combination with the shaft 13, operating substantially as described, to cause the tips of the fingers 21 21 to follow the motion of the India-rubber band, in their descent.

4. The mode of vibrating rollers longitudinally, by laying them between two vibrating arms, the one at one side and the other at the other side of the press.

5. The adjustable bearings 56, in combination with the bearingholders 57, the bars 61, and the set-screws 60, substantially as and for the purpose set forth.

6. The elastic-bands or tapes 108 108, Fig. 4, under the cylinder, attached to the rods 103 and 109 for the purpose of holding the paper to the cylinder smooth and free from wrinkles.

7. The arrangement by which the blankets and the tympan-sheets are fastened to the cylinder, consisting in the clamping-bars 114 114, Fig. 4, and 115 115, and the blanket-winders 110 110, with the hooks 112 112, or similar devices, for holding reglets around which the blankets or tympans are laid.

8. The mechanism bywhich the ink-fountain roller 38 can be turned byhand, and by which the amount of turn of this roller may be regulated from the fecders stand-.-
