This invention relates to that class of printing presses in which, given the frame, a platen and a type supporting structure therein, one of which is reciprocatory toward and from the other, the means to apply ink to the type passes between the type and platen and also around that part of said structure which immediately supports the type. aim to simplify the construction of a printing press of this type, reduce the power necessary to drive it, increase its eiiiciency and reduce the liklihood of its getting out of order and render it possible to malre readily any adjustments, repairs or the like which may be necessary,

f' and in particular to construct the'press so that it may be efficiently operated withone or more similar presses when the printing to be done requires several impressions vto beV effected at given intervals on a strip, as in twocolor or multi-color printing.

being asection through the lever andthe ful* crum support on line 8 8, Fig. 9, and Fig. 9 being a face view of said fulcrum-support,

Except as hereinafter Y indicated, both presses shown in Fig. 1 are alike, so the fol# lowing description of one will serve for both. I The main frame comprises a pair Vof up'-l rights 1 rigidly connected near their basesby the cross-frame 2 which has a vertical 'opening 3 forming a guideway for the vertically reciprocating plunger (to be described) and also has on opposite sides the projections 4 and 5, Vone to afford a bearing and the other a shelf. The said plunger, 6,. appears U- shaped as seenin Fig. 2, but each upstanding leg thereof has opposite arms 6a jand'b so arranged thatas'seen inFigs. 1', 3 and 4fthe plunger appears cross-shaped; the lower or web `portion 6c of the plunger (narrowerr4 than the upper portion) is movable vertically in the guideway 3 and in an openingforming a. horizontal guideway 7 therein slides a ,blockj 8 bored to receive an eccentric 9 liXed Von a horizontal shaft 10 which may be driven in any way and may be journaled in the crossframe 2 and in a standard 11 (Fig. 1). f When lthe shaft is rotated the plunger reciprocates vertically in the main frame.

Fixed in the legs of theplunger isa horiaontal shaft 12 on which 'is keyed a cylindrical drum 13 which is flattened asiat 13a-`13b at the top and bottom, except at the endsat the bottom which conformto the cylinder of the drum. Onrthe shaft 'revolve two gears 14, they Vbeing coupled to rotate in unison by a shaft 15 journaled in the mentioned arms 6a of the plunger and having pinions lin mesh with the gears. Shaft 15 is driven from shaft 10 through a telescopic shaft 17 (whose members are in effect splined t'o-v gether by one having a slot 17a receiving a pin 17 b in the other, Fig. and bevel geari ing 18 connecting shafts .15 and 1.7 and Vbevel gearing 19 connecting shafts 10 and 17; 'thel `l lower member of shaft 17 is journaled and supported inY the projection 4 oftlie cross-l frame 2 andthe upperV member in a`yole20 (shown only in'Fig.V 2) which is hung from V rolling Contact with its distributing and type surfaces, as followsz' Y i There are in the present case two setsof these inking rollers, `22,fdiametrically opposite each other. `Each inkingrollerineach set has its shaft 23 movable'inraydiall slotsl 24 in the two gears andurged toward the. axis of the gears springsf25attached to thev gears; on the shaft of each roller is a pair of hard (as steel) rolls 26 which run on the end or more completely cylindrical portions of the drum 13. As the inking rollers are moved around the drum by the gears they travel in a cylindrical path except at thel top, where they follow the planiform face of the type; the flat 13b at the bottom and between the ends of the drum affords desirable clearance for` cleaning each set ofV inking rollers (then held spaced from such flat because their rolls 26 are resting on the 'cylindrical ends to wit, flanges 13o of the drum) on bringing the gears to rest with suoli roller set opposite said flat. The slotsg24 are open at theiri'outer ends to permit each roller to be removed for repairs or` replacement, as uponshifting the same lengthwise until one end clears therim portion 14a (Fig. 5) of the gear 12.

A pair of transverse shaft-like eccentrics 27 have bearings in the uprights 1 above the drum and cranks 28 thereon are connected by a link 29 so that they rock together; either crankv may have a handle'30. 0n one of these shafts is fulcrumed the carrier 31 for therplaten 32 having a fork 32a and on the other is a sleeve 33 having a radial headed screw Y330i adapted to be received by the fork, which may then be clamped to the sleeve by the screw. The carrier and sleeve forni the platen frame which may be raised from the type by turning the two yeccentrics 27; such frame is further capable ofrdisruption upon -loosening screw 330J and turning the sleeve on'its eccentric 27 sufficiently to permit the vcarrier part of the frame to beVV swung up on the? other eccentric as an axis, as when it is necessary to remove the Vplaten facing and substitute another. Y f v On a plater34 securedron projection 5 of the cross-head 2 is an upstanding transverse wall 35 having Van inclinedY top to which is secured an elastic blade 36fwhoseY lower edge is bent off andbears longitudinally of Vand against a roller 37, the bla-de and roller together forming with endwalls 35a an inkfont; the pressure'of the blade-edge against the roller may be varied by an adjusting screw 38 tapped into wall 35, such adjust-` ment vdeterminingthe amount of ink which will pass the blade and remain adhering to the rollers surface. roller37 is effected by providing its shaft 37 a which is journaled in the end walls 35a, with a ratchet 39 with which is engagedA a pawl 40 pivoted to a lever 41 fulcrumed on said shaft and'connected with one of a-pair of brackets 42 on the arm 6b of theplunger 6 by a link 43. Due to theV motion of said f plunger the ink is constantly fed from the font, being distributed over the periphery of the roller v37 In the arms 6b is ournaled the shaftof'anV ink-feed roller 44 which has a pinion 4,5 in mesh with one of the gears 12` Rotation of the fonty and to the periphery of which the ink is .delivered from font roller 37 Yas will appear. When the inking rollers 22 pass this roller their rolls 26 ride over cams 46 on the drum 13, causing rolls 22 to be revolved by and thus take the ink from the ink-feed roller. The ink is transferred from the font roller to the ink-feed roller by a transfer roller 47 which vis j ournaled in a pair of levers 48 fulcumed in theY brackets 42 and normally urged by springs 49 connecting them with some part of the press, as the projection 5, to hold the transfer roller against the ink-feed roller, but adapted to be shifted,to move the transfer rolleragainst the font roller 37 each time the plunger descends, thus to ink the trans-` fer roller, by thereupon engaging stops on the plate 34.

The supply of paper A to be printed is herev vshown as a roll 51 mounted on a shaft 52 j ournaled in brackets 53 on the frame of the righthand press in Fig. 1. By means now to be described it is withdrawn from the roll.' step by step, being kept in a horizontaly plane under the platens of the two presses by suitable guide-rollers at 54. On brackets 55 on the frame of the left-hand press are mounted stands 56 in which and in blocks 57 slidable vertically therein are respectively journaled the feed-, rolls 58 and 59, the blocksy being subject to the downward pressure Vofl springs 60 interposedbetween them and adjusting screws 61 in the stands. A. passes between these feed rolls. Roll 59 hasy fixed on its shaft a ratchet 62 and journaled on its shaft aV member comprising a disk 63, carrying a pawl 64`spring-pressed against the toothed surfaces ofthe ratchet,"

and a pinion 65. Thismember is oscillated, so that the pawl will impart rotary advances to the roll in the direcl'pion to feed the paper' A, by arack 66 engagedvwith pinion 65, said.

Ad-

The papery 'ustnient is effected b releasing nut 74 turny i: a

ing screw 70 to adjust the block 71 one way or the other and hencethe stud or fulcrum in` thecslot ofthe lever, and then re-tightening` the nut yto clamp the lever to the stud.'Y

There maybe means to sever kthe paper vstrip on each printing impression. Thus 75 joined together by a bar 79' which rides on a cam 8O on the shaft l0.

' The frames of the presses are mounted to slide toward and from each other on a bed`8l, they having underneath racks 82 engaged by pinions S23-either of which by a crank applied.V

to' its stud V`84 maybe turned to adjust each press toward and from the other' `(Fig. I). To permit this adjustment shaft l0' is formed in two sections connectedV to rotate together by a coupling sleeve 85' on. one in" telescoped arrangement with the other, the latter being in effect splined tothe sleeve, say by having a slot 86 receiving a pin 87 in the sleeve.

Operation: lV'ith shaft l0 in rotation the plunger reciprocates to cause the type to coact with the' platen to print and the inking rollers are caused by the gea`rs'l4 to travel aroundv the druln'l to distribute the ink which they receive Vfrom the ink-feed roller 44 over the cylindrical portions of the surface of the drum and to ink the type. The flats 13a and 182) and the cylindrical or inkdistribution portions of the'drums surface occupy approximately equal or quarter sectors of the drum, wherefore the gearing is suchthat during-that half of each cycle in which the plunger is retracted from the platen one or the other set of said rollers runs over thev type and in the remaining half of the cycle said rollers run over said ink-distributing portions of the drums surface.

As each set of rollers reaches the ink-feed roller 44 it receives ink therefrom as explained, and each time the plunger rises v roller 44 in turn receives ink from the transfer roller 47 which on the previous descent of the plunger received ink, as explained, from the font roller 37. Of course these operations apply to both presses. vMeanwhile the feeding of the paper step by step and the severing thereof proceed as already fully explained, the paper being of course at standstill each time a printing impression occurs.

So far as I am aware I am .the first not only to reciprocate the plungers of two presses of the class to which my invention appertains from a common shaft, as l0, but to provide for the adjustment of the presses toward and from each other. This latter is a valuable feature of my invention in that, in the case where the material being printed is in strip form, as A, and its increments of advance are equal to the end that the centers of the printed impressions will be equally spaced, and the press which effects the second impression (here the left-hand one) should do'so in a definite relation to the impressions effected by the first (or right-hand) press, as in twocolor printing, it makes it possible to obtain registry ofthe impressions of the two presses although the spacing oftheimpressions for one stripy to be printed may'require to be'different from that of another such strip. l
