PRINTING-PRESS.

Specification forming part of Letters Patent No. 38,78 l dated June 2, 1863.

To all whom it may concern:

Be it known that we, GEORGE J. HILL and WILLIAM H. BAKER, of the city of Buffalo, county of Erie,and lState of New York, have invented certain new and useful Improvements in Printing-Presses; and we do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings and the letters of reference marked thereon, in Which- Figure lis a side elevation of our improved press. Fig. 1I is a vertical longitudinal section, Fig. Ill is a front end elevation, and Fig. IV is a plan, ot` same. Fig. V is a detail view of one of the cross-heads.

The nature ot' our invention relates, first, to the combination of two or more reciprocatingA cross-heads, each carrying a form 7 of type, with an inking apparatus capable ot inking each form of type with a diierent color, and an intermittent feed-motion, whereby cards or railroad-tickets or other similar varieties of printing may beprinted in two (or more) colors from a continuous sheet or roll of paper or card-board by one passage through the press, second, in. giving a vertical reciprocating motion to the cross-heads, which carry the forms of type, by means of cams of such form as will cause the cross-heads to remain stationary a certain length of time at each end of their movement, in combination with a cam for giving a reciprocating motion to the inking-rollers of such iigure as will cause the inkin g-rol1 ers to pass in under the cross-heads and return, evenly distributing the ink upon the face of type, while the cross-heads are stationary, and to then remain stationary while the crossheads complete their movement; third, in the construction of a variable intermittent feed-motion, by which the paper or card-board may be properly and accurately fed, to receive the impression from the type, from a continuous sheet or roll of paper or card-board; fourth, in the combination, with a printing-press, of circular revolving cutters, by which a sheet of card-board or paper may be out into any required number ot' narrow strips while passing through the machine.

Letters of like name and kind refer to like parts in each of the gures.

A A represent the side frames of the machine, which support the various operating parts.

B B represent two cross heads, which have a vertical up-and-dcwn movement, beingguided in said movement by the jaws c of the side frames. They lie parallel to each other,

and move at the same time. It is to the under side of these cross-heads that the form of type is secured, by being locked in a chase,

B', which is held in place on the cross-head by the slides b2, connected to each end of the cross-head, so that the chase may be readily removed or slid back into place, as required.

C C represent two bed-plates lying directly beneat-hthe cross-heads, and supported upon the adjusting-screws c', which work in lugs c2,

projecting inwardly from the side frames. lThe paper is fed over these bcd-plates, and lies upon them to receive the impression from the cross-heads, which is given by their downward movement.

D D represent two camshafts, placed one i' beneath each cross-head, having suitable bearings in the side frames. Upon each end of each shaft is placed a cam, by means of which the cross-heads are raised and lowered.

E represents the cam. Itsgure is composed OI" two concentric parts, d d2 and cl3 d4, the radius ot' the one being as much greater than the radius of the other as the required throw of the cam. The length of the segments d cl2 and d3 d4 are equal to one-thirdof the circumference, (more or less.) The ex` tremities of the segments are connected by the eccentric or cycloidal curves d d3 and d2 d4.

The property of this cam is that all lines drawn through the center upon which it revolves and terminating in its periphery are of equal length.

F F represent yokes within which the cams Y is guided in the movement which the revolution of the cam gives to it by the cam shaft, which passes through the sides of the yoke, they being slotted to allow it to do so, as shown at g2. From the peculiar figure of the cams their revolution causes the cross-heads to rise and remain stationary for a certain length of time-ym., while the concentric segments d d2 and d3 d* are passing the friction-rollers-then to fall again to give the impression upon the paper and to remain stationary upon the impression the same length oi time that it remained stationary ofi' from it.

H represents the main drivin g-shaft, having a fast and a loose pulley, li and h2, upon one end, and a large and heavy ily-wheel, H3,upon the other. Power is applied to the pulley It'. A pinion, H, placed in the center ot' the shaft, get-rs with a large spur-wheel, D, on each of the cam-shafts D, and gives an equal motion to each.

I I represent the hiking-rollers, (one to each cross-hcad,) to which a reciprocating motion is given, which causes them to pass beneath the cross-heads and roll upon the type in a manner to evenly distribute the ink over their surface and return while the cross heads are raised and stationary. These rollers are supported in a frame composed of side pieces, Ai', and cross tie-rods i2 and i3. The side pieces move in grooved guides l, bolted to the side frames, as shown at i5, parallel to the face oi' the type. The reciprocating motion is given to the inking-rollers by means of a grooved c im, J, keyed upon one of the cam-shafts D, which operates through the arms J' and J2 J2 upon the rock-shaft J3, the arm J' having a friction-roller on its end which runs in the groove ofthe cam, and the arms J2 being connected by the short connecting-rodsj* to the cross tie-rod 'i3 of the roller-frame. The figure ot' this cam is composed of a circular groove, K, concentric with the shaft D, and two opposite cycloidal curves, k' k2 and k' k3, commencing in the groove K and meeting at lr'. As the cam revolves, the end of the arm J, carrying the friction-roller which runs in the groove, will be moved out by the cycloidal curve k' k2, and drawn in again by the rever-sed cycloidal curve k' k3, the distance which the cam revolves to do this being, by construction, just one-third of a revolution, or the time the cams E are holding the cross heads up and stationary. During the other two thirds of its revolution, or while the cams E are drawing down the cross-heads giving the impression, and rising again, the circular part K of the cam holds the hiking-rollers stationary and back out of the way ofthe cross-heads.

L L represent two distributing-rollers supported by arms L', bolted to the jaws a' ofthe side frames, one behind each cross-head. These distributing-rollers are driven by the belts Z3 and Z4, connecting them with pulleys on the driving-shaft H. While the inkingrollers are held back behind the cross-heads they are in contact with these distributingrollers, from which they receive a supply of ink to ink the type for the next impression. These distributing-rollers are made to supply each inking-roller with a different color ot' ink, so that each cross-head may print a different color.

M represents a conn terbalance-weight, and m the rock-shaft, and m', m2, and m3 the counterbalance-arms and connections, by which the weight of the larger' cross-head is balanced so that itis easily moved. Both cross-heads may be counterbalanccd, it' necessary,either singly or by coupling them together.

0 represents a table over which the paper is fed, and which supports it against the pressure ofthe feeding-arms P. These arms P are supported upon a rock-shaft, 1?', which is given a motion coincident with the cross-heads by being connected to one of them by the arm P2 and connecting-rod P3. Each arm P is provided with a spring-foot, Q, having a long shank, Q', which extends up into the arm with a coiled spring, Q2, above it to force it down upon the paper. The arms P are loose upon the shaft P', but are formed with a fork, between the prongs of which is keyed or fastened to the shaft a short, curved arm, P4, which holds in place, bears against, and carries forward the arm P when the cross-head rises. The elliptic springs P5 keep the feedarms P against the curved arms when they are moving back or when the cross-heads are falling. The table O is provided with a set of riction-rollers, It, for each feed-arm. The spring-feet bear upon the paper above these rollers, so that as the feet move forward the paper moves easily with them. After the feedarms have reached the extent of their forward movement they are raised slightly up oft' from the paper, preparatory to their moving back. This is done by the movement of a rock-shaft, R', which has lifting-toes r2 projecting from it which catch in under the pins r3, projecting from the sides of the spring-feet, and raise the spring-feet from oli' the paper. The movenient of the rock-shaft is given by the bent lever R4, connecting-rod R5, and arm R6 on the end of the rock-shaft, a pin, W, on one of the cams E striking against one end of the bent lever and operating it. The spring-foo, is held up, when raised, by a springcatch, S, the hooked end of which catches in a notch made in the spring-foot. The pin r" is so placed in the cam E that the spring-feet will be lifted from off the paper while the (mssheads are remaining stationary at the upper end of their movement, so that as they begin to descend and the spring-feet to move back the spring-feet will be clear from the paper and leave it stationary until they take a new hold upon it. As the spring-feet are brought back by the downward movement of the crosshead, the spring-catches S are tripped andthe feet allowed to spring down and take a new holdupon the paper by s trikin g against the setscrews S' in the cross-bar S, which release the hook from the notch in the spring-foot.

in; 1th. d. L* d .A

es. '181 l 3 The striking of the catches S against the set-screws prevents the arms P from moving frlher, they being loose, as before stated, upon the rock-shaft P', the springs P5 yielding and allowing them to remain stationary. By simply turning the screws one way or the other, so as to lengthen or shorten the distance the spring-feet are allowed to travel before being tripped, the stift' arms P4 always carrying the feed-arms forward to the same spot, the length of feed is easily varied and adjusted according to the length of ticket or card to be printed.

The number of feed-arms upon the shaft P' and of the sets of rollers R in the feed-table O is regulated by the number of distinct strips of paper or card-board it is desirable the machine should be capable of feeding at the same time. Each feed-arm may be made to feed different lengths of cards or tickets without in the least interfering with each others action.

S3 represents guide-strips,screwed upon the table O, to guide the strips of paper or cardboard as they are fed through the machine. They are adjustable for different widths by the slots and screws S4.

T and T' represent shear-cutters. connected to the front end of the machine for cutting oft' to the proper length the printed cards or tickets as they come through the machine. The lower shear, T, is connected to the main frame by the slotted arms T2 and bolts t3, so that it is capable of being adjusted for different lengths of feed. The upper shear, T', is hinged to the lower one, as shown at t4, its moving end being guided and held against the lower shear by the spring t5. Motion is given to the upper shear by a grooved cain,U, on one of the cam-sh afts D,operatin g through a lever, U', which carries a roller in one end, which runs in the gioove of the cam, and a connecting-rod, U2, which connects the opposite end of the lever to the movable end of the upper shear.

V V represent two circular cutter-shafts, placed just behind the shear-cutter, they being supported in a frame, V', bolted to the side,

frames. They are geared together by small equal gear-wheels o2, keyed upon one end thereof, and are driven by a belt, c3, from a pulley on the main shaft ll,actiug on a pulley t n the lower cutter shaft.

W W represent the circular cutters for cutting a wide sheet into narrow strips while passing through the machine. Those upon the lower shaft are held in place by set-screws, so that they may be moved and xed on any part of the shaft, according to the widths into which it is desired to cut the sheet of paper. The upper cutters are free to move longitudinally upon their shaft, but are caused to revolve with it by the set-screws zo', which enter a longitudinal groove in the shaft. The diameter of the cutters is such that their edges lap past each other, and the upper is held against the lower by a spiral spring, w3, compressed between it and a collar, 104, which is also movable and held by a setscrew at any desired placed upon the shaft.

This printing-press is specially adapted and designed for printing railroad local and cou` pon tickets, and also railroad show or advertising cards. Y,

The machine may be adapted to print any required number of different colors by the addition of a cross-head B for each color.

In making up the forms for any card or ticket, such part as is to be printed in one color-say black-is made up and secured to the first cross-head, and such part as isto be printed in another color-say red-is made up and secured to the other cross-head, and so on, for such additional colors as the machine is constructed to print. The first ticket or card printed will first receive the black impression, and then be fed along until it comes beneath the second cross-head,when it will receive the red impression, after which each downward movement of the cross-heads will print the black part of a new ticket and the red part of the iirst, second, or third ticket in advance, according to the number of tickets necessary to lill the distance between the forms on the two cross-heads.

What we claim as our invention, and desire to secure by Letters Patent, is-

1. The combination of two or more reciprocating cross-heads, B, each carrying a form of type, with an inking apparatus capable of inking each form of type with a different color, and an intermittent feedmotion, whereby cards or railroad-tickets may be printed in two or more did'erent colors by one passage through the press, substantially as herein described.

2. The giving of a vertical reciprocating motion to the cross-heads B by means of cams E of such form as will cause them to remain stationary a certain length of time at each end of their movement, in combination with a cam, J, for giving a reciprocating motion to the inking-rollers I I, of such iigure as will cause the inking-rollers to pass in under the crossheads while they are up and stationary, and return, evenly distributing the ink upon the face of the type, and to then remain stationary during the down-and-up movement of the cross-heads, substantially as described.

3. The feeding-arm P, spring-foot Q, curved arm P4, elliptic spring P5, and spring-catch S, the lifting-toes r2, and adjustable trippingscrews S', with a feed-table, having rollers It, the whole combined and operating to form a variable intermittent feedmotion, substantially as described.

4. Thearrangement of a number of the feediug-arms,P, or their equivalents, upon a rockshaft, P', and their combination with a printing-press, so that they may be made to feed simultaneously a number of distinct strips of paper or card-board, and to give any length of feed desired to each strip, so that anumber through the machine,l substantially as deot' different tickets of different lengths may be scribed.

printed at each impression substantiall as herein set forth. 7 y i 5. The combination, with a printing press, Q

of circular revolving cutters, by which a sheet Witnesses:

or roll of paper or card-board may be cut into J. W. MCKEE,

any required number of strips while passing W. H. FORBUSH. f'
