This invention relates to a machine for making multiple copies as in printing, the object being to produce a machine, which may be exchangeably employed in the production of multiple copies as in printing by type-printing, stencil printing and lithographic printing. The invention is adapted to carry out any'of these processes by employment of an interchangeable form, mountedon a reciprocable bed-plate by which the several forms carrying the matter to be illustrated may be rapidly and effectively copied.
In carrying out the invention I employ a reciprocable bed operated by hand or power,
in which the forms are properly locked in place and passed to and fro under a stationary weighted roller for effecting an impression and means for translating a sheet of paper automatically fed up to the roller and carried in guides around its contour for delivery. The bed plate or platen is reciprocated by a sprocket gear and chain, the latter carrying a lateral pin engaging a slotted upright post on the platen, and the varied frame or chase carrying the matter to be printed is properly. secured on the platen or bed plate and passes under a plurality of inking rolls to inkithe flat relief surface of the exchangeable form carrying type or other printing surface to retain the ink. The pa per is fed over a thin slotted platform fixed above the plane of the inking rolls, and maintained in position by a pair of tiltable translating fingers to transfer it to the impression roll and the latter is mounted in a slotted frame automatically rocked to raise or lower by the" reciprocatory movement of the bed plate. The invention embodies means for effecting these results by the movement of the bed plate feeding the paper and making an inked impression for any kind of printing surface whether lithographic stone, a zinc plate, a type surface or a mimeographic surface. 7 1
The several features of novelty will be more fully hereinafter described and will be definitely indicated in the claims appended to the specification.
. In the accompanying drawings illustrating the invention Figure 1 is aside elevation of a press adapted to carry out the invention Figure 2 is a plan of the Same;
Figure 3 is an end elevation;
Figure 4 is a side elevation;
Figure 5 is an isometric view of the bed plate; I
Figure 6 is a sectional detail of paper feed device taken on line 66 of Figure 5. I Figure 7 is a form adapted for mimeograph work. V
V Figure 8 is a horizontal sectional view taken through the impression roller.
Figure 9 is a fragmentary detail perspective view of the paper guiding means.
Referring more particularly to the drawings:1 represents the base of the machine and is provided with a plurality of rubber supports 2. 3 represents a reciprocable bed plate movable to and fro on the supporting base and guided by pairs of transverse rollers 24, driven by a sprocket chain 4, engaging a pairvof sprocket gears5-5a, actuated by a hand wheel or pulley for power. One of the links ofthe sprocket chain is provided with a lateral pin 8 engaging the slot in a vertical post 9, Secured'to the platen or bed plate. Laterally projecting from the sides of the bed plate at each end is a pair of'pins 1010a; which on their translative movement engage the opposite side edges of a pair of pivoted slotted arms 11 housing a pair of journals 12, of a roller 22 to efiect an impression. The arms 11 and 11a are connected with links 13 and 13a and the latter in turn are likewise joined at their op osite ends with toggles 14. The toggles eing rockin ly mounted upon pivoted links 14: mounted or oscillating reciprocating movement through the instrumentality of a floating fulcrum in the nature of transverse pins, such as indi cated at 15, projecting within the vertical slots 16 disposed at appropriate points in the lengths of longitudinal bars 16 The extremities of the latter mentioned bars are connected with terminal vertical posts 7 and 7a. Fixed plates 16 carried by the base 1 carry trunnions 16 having eccentric pivotal connectionwith the links 14. On the rearward movement of the bed plate the post 7 is engaged and shifts to the left, the bars 16 carrying slot 16 thus collapsing the toggles and allowing the impression roller 22 to drop in the slotted arms 11-1la and the pins 10 striking the arms tilting them to the left and causing roller to rise on the inclined frame and to: the raised dotted position shown in F igure' l of the drawings to free the 'roller from the printing surface. As bestflillustrated in Figures 1 and 4 of the drawings, a sliding bearin support'42 is providedfor the journals 12 by means of which the-impression roller 22 supported thereby may be shifted toward and away-from the: inking rollers 23 and the paper respectively and locked inthedatter positiomas against vibratory motion 'created by the springs 20by the links le located in thepaths vofmovement thereof.
A pair of pivoted barsi 18 mountedat' the rear of the machine permits the frame 19 carrying the roller 22 to shift vertically and may beyieldingly-and accuratelyiadjusted by a set screw 19,? putting tension on the' spring 20"conne'c'ted to the: roller frame. =The=set screws 21, restrict downward movement'of the frame 19 and' perm'it accurateregistry of the roll to eiit'ect.a: proper[impression .On alternate movements the engraved Or'IilllUS- trative surface :is' carried winder: a train of inking rolls 28iin 'gear with thewoperating mechanism by 1 which: the rolls :aie supplied with'ink for surfacing the particular form locked in th e "bed plateland guided in' a 1 true rectilinear motion by means of the symmetrical rollers 24 mounted" and: supported 'on the baseofthepress. -At. one end of the machine is provided a thin: rigid platformr25 sloted vat26on'whioh the :paper on which the impression is-to be made is placedmnd'guided by a pairwof ifingers 29-:29a, 'carryingt'flat rectangular edges '27 "engaged by springs. 28 which. are automatically operatedhythemoringbed plate to? averticallposition as in dicated in full lines inFigure 6, or in positionindicated I-in dot therein. On shifting of thebed plate to the printing position 'thefingers eugagera fixed transverse bar 34 and are folded to a horizontal position and on return move- :ment of the bed plate aslopingface 85 of the fingers comes into engagement with: the posts 7a and are shifted to vertical positions, thereby raising sax d lingers 1 11. a plane to engage the' next succecding'sheet-of paper and carry itforward thru the s'lots"26-I26a er the paper support. As it is shifted; forward the edge of the paper traverses an. inclined guide 25 bywhich it is led beneath the roller "22-and'guided loya plurality of roller guides 29, engaging the face of the ro'ller22 1 and delivered t-o-a series of slats 3O 'moun'te'd on arms 31 carried by theroller frame-19,*at
the end'of the platen movement to 'theright it engages thegposts 7m and shiftsd'iiik 16 raising the toggle 'and'the pin 10a engages tbe.-1 oller 22 and the succession of roller guides 29 rotating against the face of the roller '22. The printed sheets upon being shifted upwardly and outwardly above the points of connection between the roller 22 and! theuuppemnostsof: the: roller, guides 29 has the unprinted side thereof momentarily reposing against the-slats 30. =The 'roller 22 during PTOQTESSiVG revolutions in l a counterclockwise direction causes the uppermost of the roller guides '29 to rotate inacountcrclockwise 'di1'eCl310n"-Wl1(3 18l)y tl1e *lOWeI 6dg6S of the sheets v i'll be elevated anditheunprinted habits or 'faces' of the sheets will then skid downwardly and outwardly upon the inclrined shelf 32 for subsequent disposition and stacking within a fixed paper support 33a. The fingers 29 a and 290; will anateri ally onset with the inclined. guides '25 and the guide rollers '29 operating against't-he face orsurface of the roller 22 in the discharge of the sheets and in viowof the fact that the roller 22 engages thesheet in advance of the inclined guides 25, it'isto be note'd'that theroller effccts an'imp-ression on the paper against the ink surface of the form. The reci-procable bed plateis provided with a pair of set screws 36-36a for'lock'ingany'formof the printing chase containing type matter --for which may be held by a pair of projecting" plates 37- 3i'ra-over-lapping the form. In place of the printing chase may be a frame38-supporting mimeo'gra-ph stencil or-a sheet of zinc 39 locked bya pair of bails 40, covered by a layer of permeable material M ant! thus varied 'type' matter may beapplied to the bed plate and dilferent forms of printing reproduction may be enchangeably carried. out'in a single printing press.
