SPECIFICATION forming part of Letters Patent No. 478,760, dated July 12, 1892.

Application filed September 2, 1891. Serial No. 404.502. (No model.)

To all whom it may concern:

Be it known that I, ENOCH PROUTY, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Printing-Presses, of which the following is a specification.

My object in this invention has been to produce'a cylinder press which shall be better IO adapted to ordinary job work than the prevailing styles of such presses, and which shall alsobe simple and economical to manufacture and be capable at the same time of doing superior work.

The improvements relate in the main to the actuating mechanism for moving the typebed, to the means employed for regulating the impression, to the means for lifting and lowering the impression-cylinder, to the de- 20 vices for securing the tympan-sheet to the impression-cylinder, to the peculiarly-acting grippers and their actuating devices, and to the peculiar paper-gages and means for operating them.

The nature of all these improvements as well as other features of the invent-ion are fully illustrated in the accompanying drawings, and will now be described.

The drawings which form a part of this 30 specification, and in which similar letters and figures of reference indicate like parts, show at Figure 1 a plan, and at Fig. 2 a side elevation, of my improved press. Fig. 3 is a vertical section on the line 3 3 of Fig. 1. Fig. 4 isa sec- 5 tion similar to Fig. 3, showing the parts in a different position. Iig. 5 is a partial plan of the impression-cylinder and the gripper-op erating cams. Fig. 6 is a transverse vertical section of the impression-cylinder, and Fig. 7 40 is a view on the line 7 7 of Fig. 5, both views showing the grippers open and ready to receive the paper. Figs. 8 and 9 are companion views similar to Figs. 6 and 7, showing the grippers as about taking hold of the paper, 5 and the paper-gage being also shown at Fig. 8. Fig. 10 is a similar section of the cylinder, showing the grippers pressing upon the paper and carrying it with them. Fig. 11 is a similar section showing the paper in the act of 50 being discharged from the cylinder. Fig. 12 is an end view of the cylinder, taken at the time of the discharge of the sheet. Figs. 13 and 14 are details showing the operation of the devices for securing the tympan-sheet to the cylinder. Fig. 15 is a detail sectional view of the fly-operating pitman. Figs. 16 and 17 are details of the devices for oscillating the eccentrics which lift and lower the cylinder, showing the posit-ions of the same. Fig. 18 is an elevation partly in section,showing the manner of supporting and actuating the inking-rollers. Fig. 19 is a partial plan of the parts shown at Fig. 18. Fig. 20 is a detail section of one of the type-bed-supporting rollers and its adjustable bearing. Figs. 21 and 22 are respectively an end elevation and a vertical cross-section of the ink-fountain and its roller, showing the manner of actuating the latter and of bringing the intermediate-roller, whereby the ink is carried to the distributing-roller, into contact with the fountain-roller. Fig. 23 is a partial longitudinal section of one of the paper-gages. Figs. 24 and 25 are front and edge views of the fly, and Figs. 26 and 27 are top Views showing different positions. Fig. 28 is a transverse vertical section of the machine through the impression-cylinder. Figs. 29 and 30 are details showing the positions of the feed-table and gages when the sheet is first positioned and when it is delivered to the cylinder. Figs. 31, 32, and 33 are sections showing the relative positions of the cylinder, type-bed, and fly at the times when the sheet is first presentedto the cylinder, when the impression is being made, and when the sheet is received by the fly. Fig. 34 is a detail of the side guards for confining the tympan-sheet-holding frame upon its shaft.

In said drawings, A represents a suitable frame-work provided at eirher side with the series of rollers B, upon which the type-bed C is supported and reciprocates. The bed is confined at either side by the ways a, and is preferably actuated by a lever D, pivotally joined to the bed at one end, and also pivotally joined at the other end to a sliding block E, moving in vertical slideway F, rigidly secured to the frame. The lever receives motion from a pitnian G, joined to a crank g upon shaft H, carrying a gear h, meshing with a pinion I upon the drive-shaft J, carrying the fast-and-loose pulleyz' and fly-wheel j. It will be noted that by the construction shown I obtain a considerable movement of the bed by the use of a comparatively short crank at the shaft from which the power is taken, and also that the leverage exerted upon the bed is always the same, the pitman connection withthe lever and fulcrum at the slide being uniformly at the same distance from the point where the lever is attached to the bed, notwithstanding the changes in the position of the parts. By this feature I obtain a smooth, easy, and uniform movement by the bed, free from jumps and jerks.

The impression-cylinder is shown at K. It revolves alternately in opposite directions, each movement thereof in the machines thus far made by me being between one and two revolutions in extent. These alternating movements are imparted to the cylinder by the rack-teeth 0 upon the type-bed carriage and the gear upon the cylinder-shaft. The cylinder is lifted after each impression to allow the bed to run back by means suitable for that purpose, and a desirable construction of which will now be described.

At L and M are dogs on the type-bed carriage, which as the carriage approaches the limits of its travel contact with and move an arm N, one stop acting at one limit of the carriages travel and the other acting at the other limit thereof. The arm N is secured to a shaft n, carrying the members 0 of the toggles O P and having bearings at m on standards q. When the arm is moved by the dog L, it is carried in such direction as to cause the shortening of the toggles, and when struck by dog M the toggles are lengthened, as will be understood from Figs. 2, 16, and 17. The members P of the toggles are joined to circular blocks or bearings Q, having freedom to turn in their supporting-standards q, and eccentrically located in these blocks are the journals of cylinder K. It results from the construction described that when the toggles are shortened the eccentrics are turned so as to raise the cylinder enough to prevent contact with the type-bed as the latter is run back, and when they are lengthened the eccentrics are turned so as to lower the cylinder into position for action on the type when the bed again moves forward. The eccentrics move without jarring or disturbance to the machine and are positive in their action, and this entire operation is caused almost entirely without noise.

As a means of regulating the impression, I make one of the toggle members, as 0, ad justable as to length, and thereby change the position of the eccentrics and depress the cylinder to a greater or less extent, as occasion requires. This adjustability of members 0 may be obtained in any suitable way; butI prefer to make those members in two parts 0 0, the part 0 being in the form of a boltand the part 0' being a box for such bolt, with adjustingnuts 0 upon the latter at either end of the box.

A stop 19 is provided upon the frame to prevent the throwing of arm N to too great an extent by the dog M. The arm comes in contact with the stop just as the bed comes to a rest.

The arm N is provided at its lower end with a friction creating device consisting of a spring R and follower '1, both inserted in a longitudinal recess in the arm, the follower projecting and bearing upon the ways a. This friction device prevents any sudden jumping by the arm when it is encountered by the dogs, and also holds it in the position in which it may be left by the dogs during the intervals between its actuations. A lever S is also mounted upon shaft n for use when the cylinder is to be thrown off. WVhen so located,the lever may be used to turn shaft n, thus giving instant motion to the eccentrics and causing the quick raising of the cylinder whenever necessary.

The next improvement which I will describe relates to the gaging devices. At 10 is a rocking shaft extending across the press and mounted upon the standards g. This shaft carries an end gage 11 and one or more side Gages 12 are preferably pro- I gages 12 12. vided with rollers 14 at their free ends, and are also provided with collars or buttons 15, against which the side of the paper may be positioned. All the gages are movable along the shaft 10 and can be readily adjusted thereon to suit the work in hand. The gages 12 rest upon the table 13 at their free ends by gravity, and the table is made to raise and lower to give them the different positions necessary. Thus when the paper is being inserted the table and gages are lifted, as shown in Fig. 29, to bring the gaging-buttons into position to intercept the paper, and when the paper is seized by the cylinder and drawn off the gaging-buttons 15 should be lifted out of the way. The former ofthese positions is illustrated at Fig. 4 and the latter at Figs. 3 and 8. Both these changes are secured by simply raising and lowering the table at proper times, the gages being forced up by the table and falling by their gravity when the table is lowered. The means employed to give these movements to the table are the following: Upon the shaft H is a cam 16, which actuates a lever 17, rigidly secured to a shaft 18, having bearings 19 upon the standards q and carrying lifting-fingers 20. When the end of lever 17 is riding upon the circular portion of cam 16, the table is lifted by the fingers 2O sufficiently to raise the ends of the gages l2 and allow the paper to be inserted with its side against the buttons 15, and when the end of said lever is riding against the straight side of the cam the fingers 20 are depressed and the table occupies the lower position, so that the gage-buttons lie at a remove above its surface and allow the paper to be drawn off IIO by the grippers upon the cylinder K. During the lowering of the table and until after the sheets have been seized by the cylinder-grip.- pers the rollers 14 bear upon the sheets, preventing any movement by them after being positioned upon the table and securing accurate register with respect to the form. The rollers do not, of course, hinder the drawing off of the papers by the cylinder. The gage 11 may, if preferred, be otherwise supported and may be secured to the table instead of to'the shaft 10. I fashion it as shown at Fig. 2, as it is required to bear upon the table at the time the sheet is fed into position. The lever 17 is maintained in operative contact with its cam 16 by the gravity of the table 13 acting upon the fingers 20. The paper is drawn from the table by grippers 30, mounted upon a rocking shaft 31, supported in and carried by cylinder K, andat all times under the influence of spring 32, tending to close the grippers. The shaft 31 also carries alever 33, provided with a pin 34, and through such lever and pin is controlled at proper times, as will be seen later on. At 35 is an arm pivotally supported upon one of the standards g and depressed by a spring 36. This arm carries two cams 37 and 38, fashioned and relatively located as shown, and also located in the path of pin 34. With this construction of the parts the operation is as follows: WVhen the cylinder has completed its return movement, at which time the parts are in the position shown at Figs. Sand 9, the grippers are about ready to seize another sheet, but are held back by the pin 34, resting upon cam 38. As soon, however, as the cylinder starts forward the pin slips off the cam and the grippers seize the sheet in obedience to their spring 32 and continue to hold it until the prescribed forward rotation of the cylinder has about terminated, when lever 33 encounters a stop 39 upon the bed-carriage (Figs. 1 and 12) and is actuated thereby in a direction which opens the grippers and releases the sheet. (See, also, Fig. 11.) The backward rotation of the cyl inder now commences and during such movement the pin. rides over both cams 37 and 38, being lifted by cam 37, the edge whereof first encountered projecting inward toward the center of revolution, as shown. The backward movement ceases as soon as the pin has passed over cam 37 the second time and leaves the pin resting upon cam 38, as seen at Fig. 9. During the forward movement, which now commences, the pin travels under cam 37, and at the second encounter in the same movement it passes under both cams, being permitted to do so by reason of its being drawn inward by spring 32, and if there should be any contact with the cams during the forward movement the cams readily raise out of the way. The cam 38 is abrupt at the side from which the pin falls in closing the grippers, so that the latter are rendered very quick in their action. It will be noticed that the table is raised during the backward moveverse pivot,so it may be rocked into and out of the locking position. A stop-pin 43, s'ecured in the cylinder-head, acts with this arm in looking the shaft 41. is riveted at its ends to side guards 4545, and said guards are adapted to partially embrace the shaft 41, and thus to confine said frame thereon. Supposing now the tympan-sheet to be placed upon the cylinder with its edges turned inward at the opening 46, and the se- A U -shaped frame 44- curing devices to be in the position shown at Fig. 14, the edges are fastened by turning shaft 41 to bring the fingers 40 against one edge of the sheet and rocking the arm 42 until it engages with the side of stop 43, as seen at Figs. 5, 6, and 13, tl1ereby creating pressure by the fingers upon the sheet. The other edge of the sheet is held by the friction created by the frame 44, which is turned from .theopen position given at Fig. 14 to the holding position at Fig. 13. The frame 44 is recessed at 47, so that when opened said recess will be engaged by the gripper-shaft and prevent withdrawal of the frame. The grippershaft also serves to limit the movement of the frame in opening. The paper when discharged by the cylinder is received by a fly '50, mounted upon a shaft 51 and oscillated at proper times by crank 52 and pitman 53, receiving power from-shaft H. The pitman and the devices for actuating it are both novel in their construction. The stem or body of the pitman is hollow, and in it are placed a spring 54 and a follower 55, having a shoe 56, bearing at all times upon shaftH. The pitman is also provided with an enlargement 57 at its end, having an elongated slot 58, through which the shaft H passes. The part 57 carries at its extremity a roller 59, bearing upon the outer surface of a cam 60, mounted upon the shaft H, shaped to move the pitman in one direction. It will be seen from this construction that the pitman will be moved back and forth in one direction by the cam and roller and in the other direction by the spring. As the pile of printed sheets increases in height the range of movement of the fly in depositing the sheets is gradually lessened, and hence in such movement I employ the spring as the motor, as the spring allows the fly to accommodate itself automatically to the height of the pile. The return movement is prefer ably positive and caused by the cam and roller. The pitmans travel is essentially a reciprocating one, varying with the variations in the extent of the movement of the fiy.

The inking-rollers which apply the ink to the form are two in number, as shown at 70.

IIO

'riage and with said gear 74. The curve of the ways 72 is upon a circle struck from the axis of distributing-roller 73, so that any adjustment given roller relative to the typebed will not affect their contact with the dis tributing-roller.

The ink-fountain inclosure is indicated at 76, and in it is placed a feeding-roller 77, carrying at one end a ratchet-Wheel 78, receiving a step-by-step rotation from a pawl 79 upon a swinging lever 80, actuated from the type-bed at the end of each movement in one direction by the contact of the lever with the dog 81 upon the bed-carriage. A spring 82 returns the lever after each actuation thus received.

Between the fountain-roller and the distributing-roller and moved back and forth between them, so as to carry charges of ink from the former to the latter, is a carryingroller 83, mounted in arms 84, pivoted stationarily at and carrying lifting-rollers 86.

Attached to one end of the type-bed carriage are inclined cam-surfaces 87, which pass under rollers 86 and lift them, so as to bring about contact between rollers 83 and 77. When they pass out from under rollers 86, the arms 84 fall by gravity and bring about contact by roller 83 with the distributing-roller 73.

The pivots b, which carry the rollers B, upon which the type-bed moves and is supported, are each adjustable vertically, so as to raise or lower the bed when necessary. This ad justability is obtained by forming the pivots on the ends of the bolts 1), which are tightly held in the frame, and by making them eccentric to the axis of such bolts, as will be understood from Fig. 20. With this construction the vertical position of the rollers is changed, as required, by simply turning bolts 1) in their sockets in the frame.

The gages 12 are preferably made adj ustable, so that the buttons 15 may be moved toward or from the shaft as required to bring the paper into position. This adjustability is obtained by securing the gages in hollow holders 21 and moving them in one direction by springs 22, confined in the holders by pins 23, and in the other direction by thumb-nuts 24 upon the threaded ends of the gages and bearing against the holders.

The fly is constructed to grip the sheet in order to insure drawing it from the cylinder and to overcome its tendency to cling to the cylinder. For this purpose I give one of the bars 61, forming the fly, a slight flexibility, so that it and the bars 62 at either side of it may be forcedinto different planes, as seen at Figs. 25 and 26, by the spring 63, secured to bar 61 and bearing upon bars 62.

At 64 is a guard, also secured to bar 61 and carrying lateral projections 65, standing out in front of the plane of bar 61, and also extending upwardly above the plane of guard 64.

The operation of this part of my invention is as follows: When the fly rests against the support 66 in position to receive the sheet from the cylinder, the devices actuating the fly will overcome spring 63 and bring all the bars to the same surface plane, as seen in Fig. 27. This allows the paper to slide down on the fly until it encounters the top side of guard 64. At this time the lower edge of the sheet will have entered between the upwardly and outwardly standing projections 65 and bars 62. As soon as the fly moves away from support 66 the bars spring back under the power of the spring to the relative position given in Fig. 26, and thereby -force projections 65 against bars 62, thus gripping the sheet and drawing it from the cylinder. When the fly strikes the discharge-table or the pile of sheets thereon, all the bars again come into line, thus carrying the projections 65 away from bars 62 and releasing the paper, which falls out onto the table.
