CYLINDER PRINTING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 344,111, dated June 22,1886,

(No model.)

To all whom may concern:

Be it'known that 1, JOHN M. JONES, of Pal- 1nyra,-in the county of \Vayne and State of New York, have invented certain new and useful Improvements in Cylinder Printing- Machines, of which the following is a specification. I

This invention relates to that class of printing-presses in which a horizontal reciprocating type-bed travels beneath an impressioncylinder, said cylinder being geared to rotate first in one direction and then in the other, according to the direction in which the typebed moves, and furnished with mechanism for raising it clear of the type on the return movement of the bed.

The improvement consists in various fea tures and details of construction hereinafter fully set forth and claimed.

In the accompanying drawings, Figure 1 is a perspective view of the press; Fig.2, a side elevation of the driven side; Fig. 3, a detached view of the tape and finger mechanism for discharging and piling up the printed sheets; Figs. 4 and 5, detached views of the mechan: ism for elevating and lowering the impressioncylinder; Fig. 6, a perspective view illustrating the construction and arrangement of the distributing-rollers and ink table or plate to permit ready access to the type-bed and type; Fig. 7, a detail view of the clip or fastening for holding the rollers in their frames; Fig. 8, a detail view of the ink-roller supports and adjusting devices; Fig. 9, a detail view of the adj ustable crank-pin.

The purpose of this invention is to simplify and improve the construction of this class of presses, to facilitate the placing, removal, and correction of the form, and to avoid undue jar and concussion in the operation of the parts.

WVith these objects in view I construct the press in the following manner, reference being had to the annexed drawings, illustrating the various features described. A strong frame, A, of metal or other suitable material and of substantially common form, is constructed to receive and support the various parts, and

'are secured horizontally troughs or boxgirders O, in which are placed carriers D,each consistiug'of a series of rollers, a, connected by side bars or strips, b, and arranged to roll or travel back and forth in the longitudinal troughs or guides, as usual.

E indicates the type-bed, provided on its under side with runners c, which rest upon the rollers of the carriers D, and are thus enabled to move back and forth with very little friction. The type-bed E is furnished at one side (or at both, if preferred) with a toothed rack, 11, which meshes with and imparts rotary motion to a gear-wheel, c, on the end of an impression cylinder, F, beneath which the bed reciprocates, thus causing the cylinder to rotate first in one and then in the other direction as the type'bed reciprocates. The type bed is reciprocated through the medium of a vibrating or oscillating arm, G, with which it is connected by a link or pitman, II, said arm projecting radially from a rocleshaft, I, extending transversely across the lower part of the frame A, and rocked through the medium of a pitman, J, connected at one end to a crankarm, f, of the rock-shaft I, and at its opposite end to a crank-pin, g, of a driven gear-wheel, K, at theside of the main frame. Motion is imparted to wheel K through a pinion, 1 on the driving-shaft M, which receives motion through a band-wheel, N. The type-bed carries the form to be printed from, and the impression-cylinder is provided with clampingfiugcrs h, which open when close to the lower edge of the feed-table B, and receives between them and the cylinder the edge of the sheet to be printed, drawing said sheet from the pile and winding it upon the cylinder as the latter changes its direction, which change occurs simultaneously with a change in the direction of travel of the type-bed, the two being geared together, as mentioned.

Thus far the machine is quite similar to others already patented or in use; but new features and improvements will now be pointed out, which distinguish this press from others.

Referring now to Figs. 1 and 2, in which it will be seen that the type-bed E travels beneath a pair of inking-rollers, O, and that an ink bed or table, I, is attached to the other side of the type-bed and passes beneath the ink-rollers, and also beneath a pair of distribof the pressframe A, the ink-table being charged with a proper quantity of ink, which similar bracket at the other side of said frame,

is evenly distributed over its surfaces by the rollers Q, then transferred to the rollers O, and by them evenly applied to the type in the usual manner. Owing to the presence of the distributing-rollers Q and the ink-table P at the point mentioned, it is difficult to get at the type-bed to correct the form or to apply or remove the same to or from the bed, while the time and labor required to remove these parts if attached in the ordinary way would be so great as to seriously impair the value of the press. To avoid such difficulty, I form or attach to the type-bed E a strong arm or bracket, R, having a sleeve, t, to receive a pintle or journal, j, formed upon an arm, S, at one end of the ink-table P, the pintle being inserted into the sleeve to form a hinge joint or connection between the type-bed and ink-table, upon which the latter may be swung outward, as in Fig. 6, to give access to the former. The free or swinging end of table P is provided with a lip or catch, 1, which drops intoa keeper, m, on the type-bed when the ink-table is in its working position, and retains it in such position until the catch is lifted from the keeper preparatory to swinging the table outward. Before thus swinging the ink-table outward, however, it is necessary to remove the distributing-rollers Q from their normal position, and to permit such removal to be made quickly and easily I construct a frame, T, as shown in Figs. 1, 6, and 7. By examining said figures this frame will be seen to consist of two end blocks or heads, a 0, connected by a rod, 1) one of the blocks pivoted in an 7 arm or bracket, q, at one side of the pressframe A, and the other seated loosely in a sothat the frame and its rollers may be swung upward to and a little beyond a vertical position at one side of frame A, as shown in Fig. 6, giving free access to the type-bed after the inlrtable is-swung out, as explained, and as 1 Block n is provided with two sockets, q, to receive the jour- 1 nals of the rollers Q at one end, and block 0 shown in the same figures.

is provided with loose sleeves 1', to receive the journals at theopposite ends of said roller, the sleeves r being arranged to slide through openings in block 0, and held in position by j spring arms or catches, which enter the notches By liftit in the sleeves, as shown in Fig. 7.

- ing the spring arms or catches s the sleeves r are released and made free to be drawn outward off the journals of the distributing-rollers, which may then be removed from plate T. The inking-rollers are similarly held in vertic allyadjustable carriers or supports U, which are more fully illustrated in Fig, 8. Each support or carrier U consists of a vertical slide, a, having a slot, 1;, through which passes a guide screw or pin, 10, which enters frame A, and serves to retain the slide in proper relation to frame A, while permitting it to rise into engagement.

and fall or to tip or to be tipped, to bring one or the other roll eloserdown to the type-bed. The upper end of each slide a is formed with a horizontal offset,-w, through which passes a vertical screw, V, encircled by a pressurespring, Y, and beneath which bear two vertical elevating or adjusting screws, W, by which both the elevation and the inclination of the slide may be regulated and adjusted. As the impression-cylinder rotates both on the inward and on the outward movement of the type-bed E, itis necessary to raise it clear of the type on the return movement of the bed, as otherwise it would receive ink from the type and impart the same to the surface of the next sheet printed. For the purpose of thus elevating the impression cylinder and again lowering it when an impression is required, I provide the mechanism shown more plainly. in Figs. 1, 4, and 5. As shown in Fig. 1, the journals at each end of thecylinder F are carried in long bearing sleeves or boxes or, pivotally supported in vertical slides b, which are raised and held up by springs c, encircling draw-rods d, which pass from the slides b downward through fixed blocks or ledges e, on which the springs 0 rest, to a crossbar, f, extending from one side of the frame A to the other. Pressure applied-in a downward direction to cross-bar f causes it to descend, overcoming the upward action of springs c', and drawing down the slides b with the cylinder-bearings and cylinder; but upon the removal of such pressure the springs again raise 'the slides and the cylinder, which latter in its elevated position is high enough to clear the type. Upon the upper side of crossbarf' are anti-friction rollers upon which bear depressing cams or eccentrics h, carried by a rock-shaft, X, journaled in the main a frame A. The rock-shaft X carries a yoke or lever, Y, having two arms, a" and j. To the upper arm, i, is attached a rod or bar, Z, having a shoulder, 70, as shown in Figs. 1 and 4, which rod takes the position shown in said figures immediately after the impression is completed.

A'indicates an upright arm rigidly secured to rock-shaft I, and provided with a shoulder, 2, to engage with shoulder 7; of rod or bar Z, and also furnished with a spring end piece or leaf, m, which on the forward movement of the arm strikes a lateral stud or roller, n, of the lower arm, j, of lever Y and rocks the shaft X forward, so as to permit the rise of thecylinder F. As the bed moves outward, the arm A swings backward and its shoulders is, riding beneath the gravitating bar or rod Z, lifts said bar until the shoulder 70 passes beyond shoulder Z and the two enter Themotion of rock-shaft I is then reversed and the arm A swings forward, carrying before it the rod or bar Z and the yoke or lever Y, to whichit is attached, causing shaft X to rock in its bearings, and to swing the eccentrics or cams h. downward upon the anti friction rollers 9', thereby depressing IIO cross-bar f, and, through the intermediate connections already'eXplained, drawing down the impression-cylinder to the required position to act upon or in connection with the type.-

The eccentrics or cams reach their lowest point or have their points of greatest eccentricity carried slightly beyond a line passing through the axis of rock-shaft X and rollers g shortly before the inner side of the typebed reaches the impressioncylinder, and they remain in such position during the impression. Just as the impression is completed, however, the spring leaf or arm at comes into contact with arm 3" or with its stud or rollerand moves said arm far enough to carry the point of greatest eccentricity of cams or eccentrics h back of a line passing through their axes and that of the rock-shaft, whereupon the upward pressure of springs c and the weight of bar Z carry the rock-shaft X and said bar Z back to the position shown in Figs. 1 and 4. By providing the spring leaf or extension m to start the rock-shaft back I effectually prevent any jar or concussion which might otherwise occur.

It often happens that for one reason or another it becomes desirable to stop the press so far as the printing operation is concerned wi thout shifting its driving-belt or stopping the prime motor, and for this purpose .I provide a swinging upright, B, which has a limited movement between fixed stops N, and through which the free end of bar Z plays as the bar is raised, lowered, and moved back and forth longitudinally. When the upright B israised to a vertical position, it lifts the bar Z above its normal position and to such height that shoulder Z of arm A will pass beneath and clear of shoulder 7a of bar Z, and as a conse quence the bar and the eccentrics remain in such position as will permit the springs c to elevate the impression-cylinder. When it is desired to again bring the cylinder into action, the upright B is thown forward into an inclined position by means of a hand'lever, 0, connected with the upright by a link or rod, 0, the shoulders k i being thus caused to engage again as explained. It will be observed that as the arm Aswings inward the shoulder l is caused to rock, so that its rear edge lifts the bar Z up and disengages the shoulders k Z as soon as the bar moves the required distance.

G indicates a rock-shaft, carrying fingers p, which receive the printed sheets from tapes and lay them upon a table, as usual; The tapes pass about pulleys r, fixed rigidly upon a shaft, 8, journaled in the press-frame, and also about a shaft or roller, t, the ends of which are faced with leather, rubber, or other flexible or elastic material, and bear against and receive motion by frictional contact from the ends of the pressurecylinder as the typebed returns after an impression is given and preparatory to another. The tapes serve to receive the printed shect'from the impression-cylinder, and to convey it to the fingers p, as is customary in this class of presses.

The roll or shaft t is carried by arms or hangers to, projecting from a rock-shaft, D, which arms are normally drawn upward to hold the friction-faces of the roll or shaft 25 against the ends of impression-cylinder F. As there is no occasion for the tapes to move while the impression is being given, and as it is undesirable that they should travel backward, as they would do at such time, a rearwardly-projectingtailoi'extension,o,isformed upon one of the arms a, and is furnished at its end with an anti-friction roller, 10', which rests upon shaft E, which carries the wheel s K. This shaft E is cut away to an eccentric form, or may be furnished with an eccentric hub or boss at 00 directly beneath the roller w, so that at the properinstant and for a suitable length of time the roller may fall and permit the spring y to raise the arm a, and to hold the ends of roll tin contact with the impression-cylinder F.

In most presses of this character it is found that the movement of the tapes received from the cylinder is insufficicnt to properly deliver the sheet to the fingers or fliers, and as a con sequence the papers are liable to be delivered unevenly or to fall in behind the fliers, and to remedy this difiiculty I provide shaft 8 with a friction wheel or pulley,z, and provide wheel K with an elastic frictional-111,2 of any desired length,whieh just as the roll it is moved from contact with cylinderF comes into contact with and rotates wheel 2, and gives the tapes the desired additional movement. Rock-shaft C, which carries the fingers p, is furnished at one end with a pinion, I which is rotated first in one direction and then in the reverse direction by a curved rack, G, carried by a rocking arm, H, pivoted to the side of frame A, thrown upward by a cam, I, on the shaft E, and is thrown downward when the action of the cam ceases by a rod, J, actuated by a spring, K, encircling said 'rod and bearing at its ends against a collar, L, 011 the rod and the end of a guidingsleeve, M, through which the rod moves, said sleeve being formed upon an arm, N, pivoted to the side of frame A.

In order to prevent the fingersfrom being thrown down with toogreat force, a second and shorter spring, 0, isinterposed between sleeve M and a head or collar, P, upon the end of rod J.

In order to adjust the pressure of the cylinder F upon the type, it is only necessary to turn the nuts Q upon the ends of the draw-- rods (1. Provision is likewise made for adjusting and regulating the movement of the bed and taking up wear of the parts, first by slotting armf and securing the crank pin or stud 1t therein by a clamping-nut, and by passing crank-pin g of wheel K through asliding block, S, mounted in the slotted end of pitman J, and movingsaid block longitudinally by setscrews T, as shown in Fig. 9.

I am aware that ink-rolls have before been arranged to swing horizontally away from the bed; but the vertical arrangement is better,

for the reason that it requires less room, and it is important in this structure because it does not in any way interfere with the inktable, which swings horizontally.

Having thus described my invention, what I I claim is- 1. In combination with the reciprocating type-bed of a printing-press, a rock-shaft connected with the bed by an arm and a pitman, and provided with an arm having aslotted end, a stud or pin adjustably secured in said slot, a driving-wheel, and a pitman connected with a crank-pin of the driving-wheel, and with the adjustable stud or pin, substantially as and for the purpose set forth.
