MACHINE FOR PBINTIG HOUSE-PAPER. i

Specifleation of Letters Patent IfIo. 8,372, dated September 16, 1851,

To all 'whom 'it may concem Be it known that I, MIL'roN D. WHiPPLE, of Lowell, in the county of Middlesex and State of Massachusetts, ha've invented certain new and useful Improvements 1n Machinery for Printing House-Paper, & c., and that the following description, taken 1n connection with the accompanying drawings, hereinafter referred to, forms 'a full and exact specification of the same, wherein I have set forth the nature and principles of my said improvements, by which my invention may be distinguished -from others of a similar class, together with such parts as I claim and desire to have secured to me by Letters Patent.

The figures of the accompanying plates of drawings represent my improved machine.

In Plate 1, Figure l is a side elevation of my printing machine, and Fig. 2 is a plan of the same. In Plate 2, Fig. 3 is a central longitudinal Vertical section, taken in the plane of the line A, B. Fig. 2 Pl. 1 and Fig. 4 is a detail sectional view taken in the same plane as Fig. 3, but looking in the opposite direction, and representing the spur clamps hereinafter described, and a part of the feeding motion for drawing the paper along to be printed. F ig. 5 is a detail plan, or top view, the wooden platform, over which the paper is passed, being removed.

The great object which is attained by my machinery, is preserving the register l (so to speak) in printing house paper, so that in printing several colors with different blocks, the patterns shall appositely fit each other, or be printed in accurate relative positions. This is done by an accurate feeding apparatus, in connection with two sets of jaws, with teeth or spurs, Which'alter` nately take hold of the paper and make circular holes in the margin thereof, on each side: one set of jaws being arranged so that its spurs shall make the holes as aforesaid, and convey the paper along, and. the other setalternately closing, (its spurs or teeth fitting into the holes already made, or others), so as to hold the paper while the impression is being pr duced, and while the first named pair travel ck to bring a fresh portion of paper along again, and then opening to permit the passage of the said fresh portion.

A A A A in the several drawings is the framework of the machine.

B is the driving shaft, having a fast pulley C and loose Apulley D, arranged in the usual way as shown in Fig. 2, Pl..1.

The paper to. be printed, or stainped, is wound uponv a roller,the journals of which rest in the bearings shown at E E, Fig. 1 Pl. 1, and F ig. 3, Pl. 2. From this roller, the paper passes up over a wooden platform F ,F, which is supported '(and moves with a horizontal sliding iron frame, G G G-.G). This frame has a reciprocating rectilinear motion imparted to it, by the following arrangement of machiner The cross shaft H, is connected, by means of the two connecting cranksv I-I, to the vertical standards K K, K K of the platen, to which a reciprocating'curvilinear motion is imparted, as hereinafter explained. The shaft H, by its connection with the platen standards K K &c., will have a reciprocating rotal'y motion, and it has a gear wheel L, on one end Fig. 3, Pl. 2, which, through the medium of the pinion (M)-and gear wheel N on the shaft- O O, imparts a reciprocating rotary motion to said shaft also. At the center of this shaft O is fixed the gear wheel P, the teeth of which'engage with those of the rack Q Q, which is connected to 'the sliding frame Gr G, by means of the screw R and slot S, in the center bai' of said frame, arranged as shown in Fig. 5 Pl. 2.

T T-T T in the several figures are the sliding clamps,which are connected to and move with the sliding frame G G &c'. The lower half of each of these clamps may bel fixe`d to the said sliding frame, but the upper half is arranged' so as to be moved verltically, by means of the guiding rods U V &'c attached to the under side of the upper half of the clamp, and moving up and down in suitable holes in the lower half of the said clamps. Attached also to the under side of the upper half of said clamps, are a series of' spurs or pins V V &c, set at proper intervals apart, over suitable holes in the lower half of said clamps. These clamps are closed when they are moving forward with the paper, and the spurs are passed through the paper' at roper points along the margin on each si e thereof, but they are 'opened when said clamps are moving backward, and the said spurs are also then disengaged from the paper. This opening and closing is efi'ected by means of the cams W W, on the upper ends Vof the arms Y Y, which arms are attached to opposite ends-of the rocking shaft, Z Z, and play through at the front of the machlne, which is .'op'er-'- proper slots'in the lower half 'o f the Isliding clamps, the cams bearing against the underside of the upper half of said clamps, as shown in Figs. 3 and 4131. 2. A metallio fork a, is secured firmly to the center of said shaft, Z, Z and embraces asmall pin b scui'd t'o "tl`-`I'e "side of the sliding rack 'Q Q. Tviis 1f`ck, as before suggested, is connected t vthe sliding frame G G G, by -the Pin R and slot S, in the center bar of said rame, but the rack always moves the length of said slot before said frame begins to move, and, by this means, and the operation of the pin b on the v fork a, attached to the shaft Z Z and cams lV W, it will readily be seen the desired opening and closing of said clamps at the proper times to effect the results above specified are secured. The set of' short statlonary clamps, (rc-cc, in' the several figures, are arranged so as to open when'the sliding clamps are closed, and are` feeding 'the paper along, and close when `the sliding clamps are moving backward.

These short clamps are provided with guiding rlods, and holes and spurs precisely similar. to those before described in the longer set. The upper halves of said clamps, rest upon the cams f-, similarly arran ed to those before described at W W, an connectedl to the ends of the rocking shaft gg, shown in Figs. 8 and 4 Pl. 2', and by dotted lines in Fig. 5 Pl. 2. This shaft i's turned by means of the depending bar h, Figs. 3 and 4 Pl. 2, firmly connected to said clasp which is'connected at one end to the right angular 'lever 'i z' The other end of said lever, playsin, and is operated by the diagonal groove. formed in the end of the arm Za, which arm is secured to the front of the vibrating frame Z Z Z, as shown by dotted lines in F ig. 5 Pl. 2.

This vibratingframe turns on the longitudinal shaft m m and is depressed by means of the cam n onl the rocking shaft Z'kZ, which shaft opens and closes the sliding clamps, and said cam is so. arranged on said shaft, as to open the short clamps when the sliding ones are closed.4 The raising of said vibrating frame and closing of the short clamps, is eflected by the bent spring o, on which said frame rests as shown in Fig. 5 P1. 2. After the paper is stamped, it. is guided' and drawn away, by the 'roller-q),

ated by the band or cord q g g Fig. 4.131. 2, one end of which cord is attached to the front of the sliding frame, G G, and passes around the groove in said roller, and around the several guiding pulleys r, 1', r &c, to the rear of said sliding frame to which it is attached, so that by thisl connection, the' feeding 'of the paper forward and the turning of said roller ;0, will correspond precisely, but when the sliding frame moves backward for a fresh portion of paper, the pawl and ratchet at 8, on one end of the roller p holds the roller statlonary, and the cord' slipspn said roller without turningit;

qhe various patterns are confined in the platen t, t, in any desired way, said platen being, as before suggested, securedt to the Vertical arms K K-K K' which arms are connected to the cranks u, u on the opposite ends of the lower transverse shaft o v. On one end of this shaft is the double grooved wheel y y, in the grooves of which, two chains are fitted, Vonel end of each chain being fastened to the lperiphery of the wheel, and the other ends being secured to the points a'-l' of the long connectin arms c' c'. This connecting arm is attac led at its rear end, to the crank d' of the shaft e' e', which shaft is revolved by means of the gear wheel on its end engaging with the gear Wheel g' on `the driving'shaft.

From the above described arrangement of parts, it will readily be seen, that the shaft 'v v will have a rcciprocat-ing rotary motion imparted to it, and that by so moving, itl gives a reciprocating curvilinear motion to the platen and its patterns, said platen alternately moving backward to get fresh color, and then forward to imprint the same upon the paper on the (sliding) platform F F; The changing or reversing of the motion of the shaft w o, is assisted by the heavy weight 'h' h' fastened to said shaft, as shown in Fig. 3 Pl. 2, and the motion of the feeding apparatus is connected to that of the imprinting machinery,iby

s means of the chain or series of gear. Wheels 71', z, between said shaft o 'vand the'shaft H which actuates said feeding apparatus.

The color for thepatterns is contained in Vthe semi cylindrical Vat (78' z'f') and it is served out for the patterns by means of the cloth band Z' Z', which is attached to and wound partially around the roller m', passing under the roller 'n' at the bottom of the vat and also under the adjustable roller 0' at the front ofvthe same, for expressing the redundant color, and connected to the cross bar p' p' of the vibrating frame p' p' g' &c. The upright arms q' g of the frame, are secured to the opposite ends of the shaft r'. Depending from the center of this shaft, is an arm s', connected by the connectinP rod t' to the arm u', which is fitted loosey on the shaft v '0. This arm u' is moved for- Ward and back by the adjustable studs o' 11', fitted in the slots w' w', cut at proper intervals apart in the circular plate fastened to and turning with said shaft -v '0. The shaft 'u o, as before specified, has a reciprocating rotary motion, and by means of the arms 8' and 'u/ and rodt' and studs 'v' v' in the plate w', connecting vthe operation of the said shaft with that of the shaft 'r", the latter shaft also has a reciprocating rot-ary motion, and, by this means, the frame p' p' g' is made to draw the band Z'l', after each impression, over the horizontal bed or frame y' 3/. While the platen is moving over to give the impression, the cloth band Z' Z' is drawn back by means of the band z' e', attaehed at one end to and wound around the pulley ai', on one journal of the roller m', and connected, through the medium of the spiral spring ,b2, to the lower end of the arm C2, which depends from the shaft 11' in a' direction parallel to the arln 8', so that, asthe frame p' p' q' vibrates to- Ward the rear'of the machine, the movement of the yarm 02 forward, will wind and draw the band Z'IZ' back through the color in the vat. In some cases it may be advisable to have the cloth band stationary, and supply it with color by a brush, which has a reciprocating motion to and from the vat. The bed y' y' is elastic, and is formed of oil cloth, secured to the edges of a square frame and resting on the horizontal supports d2 dz dz (Z2 attached to the sliding side frames 62 62 e2 82 82 82 which move up and down in proper guides, formed in the frame work of the machine, as shown in the drawings. The bed y' 3/' is made suscept-ible of a Vertical adjustment by means of the screws and nuts, shown at f2 2 Figs. 1 and 2 Pl. 1, and Fig. 3 P1. 2.

The cross bar 92 which connects the two side sliding frames 62 62 e? 82 62 62, rests oni one end of a lever hz Fig. 1 Pl. 1 and F ig. 3, Pl. 2, said lever having a fulcrum at '02, and bearing, at its rear end, against a Vertical pin cz, which moves up and down in a proper guiding hole in the framework. This pln 1s formed of a wedge shape, at its upper end, and bears against the periphery of the wheel 22, fixed' on the center of the shaft e' e'. The wheel 12 has a notch n2 into which, at every revolution of the shaft e' e',

I the end of the pin 11:2 sli/ps, and, by so doing,

allows the color bed y y' and cloth band Z' Z' .to drop, but as the pin immediately -falls or is pressed out of said notch the said bed rises again. This operationtakes place while the patterns are taking the color from the cloth band and the falling and rising of the bed and band, immediately after the first touch of the patterns upon the latter, gives the second or double application of color to the patterns, which is so univer-v sally practised in the hand printing of housel paper.

A small cam o2 on the shaft e"e' lifts the rod 722 292 so as to turn the shaft 7'2 7'2 and press the fingers Q2 Q2 down upon the upper half of the sliding clamps, and push the spurs through the paper. When, for any reason, these spurs fail to pass through the margin of the paper, the upper half of said sliding clamps will press against the stud T2 of `the right angular lever 82 82 82, and throw the catch, at the lower end of said lever, out of the notch in the lateral sliding shaft t2 t2 (to which the belt holder 16"* is attached), and allow the spring 'v2 'to move it laterally, and slide the belt on' to the loose pulley of the machine and throw it out of gear.

After the first pattern has been printedy 1. The use of two sets of spur clamps, one

set being sliding and feeding clamps, and the other set being stationary and holding clamps, and the two sets having a connected operation, so that one set shall be open when the other set is closed, all as herein above set forth.

2. .I also claim the mode herein above described for supplying the coloring fluid to the patterns, that is, by means of a cloth band, alternately drawn forward from the vat over an elastic bed, on which the platen descends, and then back again, through the color in the said vat, all as herein above set forth.

3. I also claim giving the second' or double application of the color to the patterns for each impression, by suddenly lowerin the elastic bed after the first touch of t e patterns on the cloth band, and then raising it again, for the second touch, substantially in the manner herein above set forth.

In testimony that the foregoing is a true description of my said invention and improvements I have hereunto s'et my signature this twenty sixth day of August in the year 1850. p
