PATENT ALONZO GILMAN, on 'ruoiznnw YORK.
sMPROVvEME-NT IN PRINTING-PRESSE'.
Specification forming part of Letters Patent No.- 3,716, dated August 23, lE4-L T0 all whom it may concern:
Be it known that I, ALONZO GILMAN, of the city of Troy, in the county of Renssalaer and State of New York, have invented newaud useful Improvements in Printing-Presses;- and I do hereby declare that the following is a full and exact description, reference being had Ito the annexed drawings, making part ot' this specification, in which drawings- Figure l is a .perspective side view of a u printing-press.
At c a is a pair of togglesor bracing-levers i employed to produce the impression required in printing. Y
b is thebed-plate to the chase c and the type when set and attached for printing.
At (Z the levers are united' by a socket-joint.
c .is a friction-roller for the bearing .of the levers upon the cam f, by which they are operated.
y is a vertical plate, serving as lthe platen for giving the impression, and its inner surface is adjusted -to face of the type by means of the screws shown in connection as passing th rough the fixed plate h. v
At I, Fig. 1, is acylinder for receiving, and at z a roller for equalizing upon its surface, the ink to be communicated to the inkingrollers. So far these are in common use; but the manner in which the hiking-rollers j j are suspended in the frame to which theyibelong and are operated and applied to the purposes intended being considered as new, I will here add more specifically that'k Figs. 1 and 2, are lever-arms extending from the shaft L to short sweeps connected with the lower crossvbar B of the woi'ki11g-i'ran1e M of these ink- Eng-rollers.
N is, in effect, the opposite arm of t-he same levers of which the shaft L serves. as the fulcrum. This .inner arm, X, as shown in the drawings, is so formed and supplied with appendages as to beconie connected with the cam f by means of` a flange overlapping the inner surface of its rim from each side in such manner as to slide easily upon it as the cani revolves,
and, by means of the pin-joint at p, conform to the various inclinations of surface thereby bearing of the cam upon this end of the lever. By these provisions it will be seen that the working-frame M, with the inking-rollers, receives its up-and-down motion at every revolution of the cam, causing the rollers' to pass over the face of the type as they, by the-ac` tion of the same cam in operating thc-levers a a, are withdrawn from, the platen.
In order to conform the surface of the inking-rollers to thatV of the cylinder I in receiving from it their required supply of ink, and also to the face of the type in imparting the same to them, I provide two half-circular appendages to the working-frame, one of which is shown at 1', Fig. 2, into which the respective journals of the rollers are placed. They are attached to the sidesof the frame on the inside by a central pi nj oint, so as to adapt the line of surface of each to the curve of the cylinder and to the face of the type as they pass in contact with them; and, asa further provision for adjusting their respective surfaces to each other, a transverse tongue and groove is made between each appendage or block and the side ofthe working-frame, the same, where it is attached, being extended in width for that purpose, with an adjusting-screw, by means of which the rollers are moved out or in` at discretion, and ixed in their position when adjusted, excepting the lateral circular inotion, as above provided for, upon the pinjoint, which adapts the line of surface of each to the curve of the cylinder and face ot' the type as they are respectively brought .incontact therewith.
S S are the ways vbetween which the working-frame passes in its 11p-a-nd-do\vn motion.
For the purpose of applying the machine to theprinting` ot'paper in sheets as distinguished from cards, I provide a frisket, as represented at a, Fig. 2, attached by hinge-joints to the top of theworking-trame provided for that purpose, and there shown in con nection. This frame passes up and down between the ways b b, and receives its motion tlm-)ugh the instrumentality of the cam c and the lever (l, connected with each other in thesaine manner as that above described for ol'icrating' the inkin rollers. This lever is 4made looseupon the Shaft L, so as not to turn with it, and the forni of the cam with which it is Connected, as show n in the drawings, is such that in its revolution the frisket is kept elm-'ated loir;r enough to allow a sheet to be taken ont and another put closing the friske'tv in this operation.
2 v :wie
' in before it is again drawn 'down between the type and the platen for impressment.
Friction-rollers are provided at each side rizn to vgive ease to its motion, as Well asfor Springs also are provided on the outside of one of its Wings, as shown at e e, to keep them suf-4 eiently dosed in passing, and a spring on' the inside, at, f, to separate them when brought again to the top of the machine.
1Whitt I claim, and desire te secure by Letters Patent, is'
l. The hanging of the inleing-rollers, 'in the nin-nner above deseribed, in the working-frame provided for them, by means of which they `are made conformable, in passing, to the curve y ALONZO GILMAN. Witnesses:
