IMPROVEMENT IN PRINTING-PRESSBS The Schedule referred to in these Letters Patenband making parl'. of' 'chev saine.

I, CHARLES D. WnrGnzrmGTo-N l of Fairhaven, in the county of Bristol and State ofZ Massachusetts, have invented certain new and useful Improvements in Printing-Machines or Presses, of which the following is a specication.

The first part of my invention relates to the combination of two rotating cylinders and two reciprocating type-beds, combined and embraced in the same machine in such a manner that a sheet of paper, or other material, maybe printed upon both sides at one passage through the machine. c

The type for printingon one 'side of the 'paper is placed upon one of the reciprocating beds, said bedi receiving an impression from one of the rotating cylinders; and the type for printing upon' the other side of the paper is placed on the second bed, the impression being given by the second cylinder; the object of this part of my invention being to construct a printing-machine in which either type or stereotype may be used, said machine not being'conned to the use of stereotype or cast-metal plates or forms, which must be constructed specially for the machine; the machine embodied in my invention being sc constructed as to allow the use ot' either type or stereotype, also any or all of the xturcs in general use, and not being conincd to specially constructed fixtures, thereby obtaining aprinting-machine plain and simple iu its con# struction and operation, 'so that any person skilled in the art will readily comprehend and operate the same.

The second part of my invention relates to thecom-v hination of an oscillating toothed wheel, and two reciprocating beds, by means of two racks, the teeth of said racks meshing into the teeth of the aforesaid oscillating wheel, one of said racks being attached to cach of aforesaid beds in such a manner that the oscillation ofthe said wheel shall canse thesaid beds to have a reciprocating motion. c w

In large machines it may be necessary to use a second oscillating wheel, and its two racks, upon the opposite side ofthe machine, for the purpose-of securing gneatersteadinss and ease of motion to the machine.

This part of my invention further relates to the couibination of said oscillating wheel, a revolving crank, and a pitman or connecting-rod, for the purpose of transmitting the motion from said crank to the aforesaid oscillat-ing wheel, thereby causing said wheel to oscillate or vibrate, said wheel, in turn, imparting its motion to the aforesaid beds, causing them to have a reciprocating movement.

The third part of my invention relates to the cornbination of two rotating cylinders and two reciprocating beds in such a manner that the weight of o ne of the said beds shall counterbalance the weight ot' the other said bed, the said beds being in an inclined or vert-ical position.

The fourth part of my invention relates to the combination ot' the rotating cylinder, (or corresponding part ,in any p'riming-machine` or,press,) which gives the second impression, or causes the second side ot the paper to be printed upon, and an endless revolvingor traveling apron or blanket, composed of any suitable material, the surface of which shall press or rub against. the surface of the aforesaid cylinder in such a manner that the said apron shall, by ,meansV of its contact with thepaforesaid cylinder, absorb or wipe oli" from the Asurface of saidcylinder (or corresponding part in any printing-machine or press) all ink'that may b'e offset upon said cylinder, from the Aside of the paper that was iii-st printed, while'the second side is being printed; I do not wish to confine -myselito the endless apron alone; rotating rollers may be used instead. The iifth part of my inventionA relates to the conibination ofthe nippers or fingers that grasp the paper and conline it ,to thev cylinders, and cushion or padholder ,'and the rod or shaft that operates the nippers,

in such a manner that, Vwhen the aforesaid nippers are moved along the rod orshaft, the cushion or pad-holder shall be moved atthe same time by one and the same operation, thereby rendering it very easy and convenient to adjust-the nippers and cushion-holders upon both of the aforesaid cylinders.

Having explained the nature and objects of my iuvention, I will now give a general description of the machine, and the operation of its several'parts, by referring to the accompanying drawing, the'same letters and figures referring to the same parts in each figure of the drawing.

Figure 1 is a perspective view of the machine embodying my invention, part of the feed-board repre-l sented as broken away to show parts beneath it.'

-Figure 2 is a side elevation, showing those parts that operate the rotating cylinders and reciprocating beds, also seen in iig. 1, and designated by the letters J K K', F Fl F2; also, the endless apron, for removing the offset ink from the aforesaid cylinder;ralso, the delivering-tapes and pulleys.

Figure 3 is an end elevationof that part of one of the cylinders which holds the nippers thatgrasp the paper and confine it to said cylinders, the cushion or pad-holders, and the rod or shaft that operates the nippers; said nippers are also seen at thetop of the cylinders in iig..1. l

Figure 4 is 'a plan of the same.

Figure 5- is a plan of the cushion or pad-holder, the nipper being taken away.

A A, ig.1, are two side frames, which should be substantially constructed to support and resist the strain and vibrations of the operating parts.

B Bl Bz B are the cross-ties or girts which connect the side frames A A together, yand also suppoxt the ways or tracks C O, in whichthe type-beds D D slide, also forming part of the frame of the machine.

M is the driving-shaft, which is rotated by any suitable device. 4 j L is a crank, whichreceives its motion from the shaft M.

teeth engaging with the teeth of theracks K K, said,

racks beingsecured to the type-beds D D',`the wheel J being caused to oscillate by the crank L, and pitman I imparts its motion, to the racks K K', and to the type-beds D D', causing them Vto have a reciprocating i movement in alternate directions, one of the beds going up and the other coming down, and 'vice fvcrsa, thereby causing the beds D D' to travel back and forth under the impression-cylinders E E'.

N N' are toothed racks, which are secured to the type-beds D D', and are caused to reciprocateby said beds. The racks N N are immediately behind and in fthe same plane of the racks K K', fig. 2.

The racks N N' engage with the teeth on the perimeters of the wheels F1 F, and impart an oscillating motion to the said wheels F1 F2, causing each to make one-half of a revolution. Said wheels Fl F2 rotate loosely o the shafts s s, iig. 2, of the impression-cylinders E E.

The wheel F2' on the shaft sof thecylinder .E also engages with the wheel l on the shaft s of the cylinder E', and imparts an oscillating movement t0 the said wheel E, which rotatesloosely on the shaft s.

D D' are two type-beds, upon 'which the type or forms to .be printed from are secured, and whichpass back and forth under the impression-cylinders E E'. Saidbeds D D' are connectedl with each other by the wheel J, fi'om which the said beds derive their motion; and byY which it will be'seen that the weight of one of the beds counterbalances the weight of the other hed,thereby causing the aforesaid 4beds to move up or down with the same ease and without jar. l

E E are two impression-cylinders, upon which the paper. to be printed is placed.

The cylinder'E gives the impression which prints v the irstside of the paper, and E' the cylinder which gives the impression for printing the second side of the paper.v

As the type-beds D D' move downward and under the cylinders E E', the said cylinders rotate in the same direction, and carry the paper between the surface of said cylinders and the face of thetype, and causes the paper to receive the ink from the type.

I will now describe the manner in which the impression-cylinders E E' are rotated by referring to fig. 2 ofthe drawing.

rPhe oscillating wheel J receives its motion from the crank L, fig. 1, and imparts a reciprocating movement to the racks K K and beds D D', they, in turn, imparting -the same movement to the racks N N', said rackscausing the wheels Il" Fz to oscillate one-half of a'revolution, and the wheel F2 causing the wheel F to perform one-half of a revolution at each movement of the wheel J'.

As the bed D passes down in direction of the arrow, under the cylinder E, the rack N being secured to the bed D, causes the wheel FZ to rotate one-half of a revolution in the direction of the arrow, which carries the cylinder E in the same direction by means of the spring catch or latch X, in the wheel F2, engaging with and pushing against the projection X2, `which is secured to the cylinder E; also, the wheel F2 at the l same time causes the wheel F to make one-half' o f a` revolutiomsaid wheel F causing the second cylinder E to make one-halfof a revolution, by means 'of the spring latch X of the wheel F engaging with and vpushing against the projection Xl of the cylinder E',

the cylinder E then remaining stationary until the next downwardI movement of' the bed D, by which it Awill be seen that the'v cylinder E has anintermit-tent motion. y l

When the bed D commences its upward movement the motion of the rack N1, the wheel F, wheel F, is reversed. XVhen the wheel F? has performed one-half of a revolution yin this 'direction the latch X engages with the projection `X3 ofthe cylinder E, Aand is then ready to give the said cylinder another halt' of a rev lution, as the bed D moves dowuwardin the direction of the arrow again. Thebed D', being connected with the bed D by means of' the wheel J, performs a downward movement while the bed D is moving upward.

The rack N, being carried down by the bed D', imparts its motion to the wheel F1, causing said wheel to perform one-half of a revolution in direction` of the arrow. The wheel F1, by means of the latch X, engaging withand pushing againstthe projection lX4 of the arm G, which `is secured rigidly to thelshaft s of the cylinder E', causes the said cyelinder E to make onef of a revolution. i

It will bessen by the above that the first half revolution of` the cylinder E is derived'from the downward movement of the bed D by means of the rack N', the wheel F2, and the wheel F.

The cylinderl E', therefore, has a continuous rotation, .one-half of the rotation being derived from the bed D, and the second half rotation from the bed D'.`

It, fig. 1, is the fced-board, from which the paper is fed to the cylinder E of the machine.

O O' Of O are the nippers which grasp the sheet and confine it tothe cylinders while it is being printed upon.

O O O O are the cushion or pad-holders, an elevation of the 'same being shown at fig. 3, and a plan of the same at fig. 4, and detached plan of the cushionholder aty fig. 5;

The nipper O', in figs. 3 and 4, is constructed similar to those in general use.

Said nippers require to be mpved back and forth along the shaft P, for the purpose of accommodating various' sizes of' paper.

In all machines heretofore constructed, the nippers O O'Q' O' are secured to the shafts P P, and

vthe cushionor padholders O O 0 O secured toa second or supplementary shaft, thereby causing greater complexity, bo'th of construction and operation, said Ynippers and cushion-holders being entirely independent of each other.

In order to adjust any one of said nippers and its cushion-holder, two separate operations are required, thereby causing trouble and a loss `of time to set the nipper, so that itv shall strike the cushion in the propel' place.

In my invention it will be seen that, by loosening the set-screw vn, figs.v 3 and 4, both nippel' and cushion-holder are moved along the shaft P by one and the same movement, thereby allowing them to be adjusted with ease and facility.

O, figs. 3' and5, is the cushion-holder,- of which 1 is the cushion.

i is a' projection or tongue on the outer end of said Vcushion-holder, said tongue t fitting into and sliding in the groove fi ofthe cylinder E.

I do not confine myselfto the precise arrangement of the nipper and cushion-holder, as shown by the drawing. The object of my invention is the combination of the nipper and its cushion-holder in such a manner that the operation of either will control the operation of the other.

Fig.5 is a plan of the cushion-holder, showing the manner of its construction, 1 being the cushion, which` by the nipper, which is secured bytheset-screw a. A

By moving the nipper the holder is also moved.

As has been shown'in the foregoing description, the cylinder E has an intermittent rotation.` Said cylinder istherefore, provided with twosets of nippers, one` set, O' O', seen in iig. 1, 'lhe other set is directly opposite, upon the under side of said cylinder E, (not shown in the drawing,) each set of aforesaid nippers grasping a sheet of paper alternately.

As has also been shown in the foregoing description, the cylinder E has a continuous rotation, and is, therefore, provided with but one -set ofl nippers, seen at the top of cylinder E', iig. 1. Said nippers grasp the sheet of paper and take it from the cylinder E.

Fig. 1,'j` is a tumbler, which turns the nipper-shaft P. Each nipper-shaft is provided with a similar one.

S is a pin which the tumbler f strikes against, said tumbler turning over, and thereby closing the nippers. There is a similar pin at the point where the nippers 'are opened, to release the paper, (and not ,shown in the dra-wing.) .The cylinder E is also similar pins S.' v

' The above manner ofoperatingthe nippers is adevice commonly used, and which .I vdo not claim as part of my invention.

V V1 V2, fig. 2, are the livering-tapes run.

a' al a? are the delivering-tapes, which may be -extended any desired distance by means of pulleys,

W W are cylinders or rollersV upon which the endless apron or belt Y revolves.

Said vapron is pressed against the cylinder' E by the roller W.

The roller W may be also 'used without and independent of the aforesaid .apron vY.'

Having described each part of my invention, and its operation separately, I will now describe the 'operation of the machine complete, and as a whole.

The paper to be printed is placed at the forward provided with pulleys upon which the deend of the feed-board R. It also projects over-the*- cylinder E. y

The machine is then putin motion byrotating the shaft' M, by which the crank L is `also caused to rctate, and, through the lpitman or connecting-rod I, causesA the wheel J to oscillate. The said wheelJ imparts' a reciprocating movement to the type-beds- Asthe bed D begins to descend, the wlieelF2 begins to rotate. The spring-latch X of said wheel engages with the projection X2 of the cylinder E,and causes said cylinder torotate. The tumbler f comes in contact with the pin S, and closes the nippersO' 0 upon the paper on the feed-board It. The cylinder E makes one-half of a revolution, and

carries the forward edge of the paper nearly to the type on the bed D, (at the same time the cylinder E makes one-half of a revolution, by means of the wheel F2 engagingwith the wheel F, the latch X of thev cylinder E,) and carries the paper between the vsur-V face of said cylinder and the face of the type on the bed D, and causes one side of the paper to be printed upon, (at the same timethc second set of nippers of the cylinder' E grasps another sheet of paper from the feed-board B.) The cylinder E then remains stationary, whilethe bed D again makes an upward movement, the nippers O 0', which holdthe-forwardedge of the paper, then being at' the positionag.' 2, at which position said nippers release the paper, which is selijzed by the nippers of and takenonto the cylinder P'.

While the bed Dis making aforesaid upward movement, the bed 'D' at the same time makcsa downward movement, and causes the cylinder E' to make one-halt` of a revolution, (by means 'of the wheel Fl,

is secured to the shaft s of the'cylinder E',) carrying the nippers 0' O' to the position t opposite the position t'of the 'cylinder E. The bed D' then makes an upward movement, the

nippersof the cylinder E take the paper fromthe nippers of the cylinder E, causing the side of the paper already printed to be inside and against the surface of the cylinder E', the side of the paper not yet printed being on the outside, ready to take an impression from the type onthe bed D'.'A The cylinder E' then makes one-half of a revolution, (by means of the downward movement of the bed D, which causes. the wheels'l!12 and F to rotate, andv the latch X of the wheel F pushing against the projection X1 of the cylinder .EQ ng. 2,) and carries the forward edge of the paper nearly to the type on bed D'. l

The bed D' thenmakes a downward movement, and causes the cylinder E to make another one-halt" of a revolution, (by means heretofore described,) and carries the paper between the lsurface of said cylinderand the face ofthe type on the bed D', thereby causing the second side of thc paper to be printed. When the cylinder E carries the forward edge ofr the paper opposite the roller V, fig. 2, the nippers'are caused to open, (by means already described,) and the paper is conveyed over said roller V, (by means ot' the tape al, whichpasses around the cylinder E and over the rollers V V1 V2, and under the roller W, andl agvain onto the cylinder E,)A and along the ltape a2, between the rollers Vl and V2, in the direction ofthe line l).

machine.

The manner of conveying the paper through the -`machine and the arrangement of the delivering-tapes are comm'on devices, therefore I do not claim them as 'part of my invention.
