CHARLES J. ADDY, OF MALDEN, MASSACHUSETTS.
PLATE-PRINTING MACHINE.
SPECIFICATION forming part of Letters Patent No. 341,305. dated May 4, 1886.
Application filed September 1 1884. Serial No. 141,904. (No model.)
mit the bed to readily pass in one direction.
under the roller without the latter coming in contact with the paper on the bed.
Figure 1, in side elevation, represents a sufficient portion of a press to illustrate a practical embodiment of my invention; and Fig. 2 a left hand side elevation of Fig. 1, it showing the rear end of the press.
The frame-work A, cylinder B, bed-supporting plank E, and its attached bed F, are all substantially as represented in the said patent, and in practice the plank will be operated as in the said patent, and the said parts need not be herein further specifically described. The plank has attached to it at each side two adjustable lugs, 2 3, which,- at opposite strokes of the plank, strike against first one and then the other side of the lower ends of the levers b, one at each side of the press, and pivoted at their upper ends to one of the crossrods a, common to the said patent. The impressionroller d has its journals mounted in bearing-boxes r1, placed in slots in the framework A, the said boxes resting upon spiral springs d, substantially as in the said patent. The bearing-boxes d and the blocks 6, acted upon by the screws 6, are connected by means of the togglejointed levers, each composed of two links, 4 5, jointed together at 6, the said links at their pivotal points 6 being connected by links 8 with the levers b, before described. When the plank E is fully forward, or at the front of the machine, the roller (1 will be in its lowest position, and will act upon the sheet per on the plate or bed from being borne' against the roll (I as the bed and the plate and paper thereon are again moved to the front of the press or toward the operator. As the plank reaches its position at the front of the press, the bed having been passed under and without thepaper or sheet just printed touching the roller (1, the lugs 3 strike the levers 1), moving the said levers so as to cause them to straighten the toggles and force the bearingboXes of the impression-roller and the impression-roller itself down into operative posion.
I claim- In a plate'printing press, the plank provided with adjustable lugs 2 3, at or near opposite ends on each side, combined with the impression roller, spring bearings therefor connected with toggle-levers, the levers 1), cooperating with the said lugs, and the links 8, connecting the levers I) and toggle-levers, and means to reciprocate the plank, substantially as described.
In testimony whereof I havesigned my name to this specification in the presence of two subscribing witnesses. CHARLES J. ADDY.
