UNITED STATES PATENT OFFICE.
, MERRITT GALLY, on NEW YORK, n. Y.
PRINTING-PRESS.
SPECIFICATION forming part of Letters Patent N 0. 352,237, dated November 9, 1886.
Application filed June 5, 1886.
To all whom it may concern:
Be it knownthat I, MERRITT GALLY, residing at New York city, in the county of New York and State of New York, have invented certain new and useful Improvements in Printing-Presses, of which the following is a specification, reference being bad therein to the accompanying drawings.
In the accompanying drawings, Figure 1 is a side view of the bed and platen of a printing-press with a part of the supporting-frame, and showing also the parts which give motion latch for holding the chase in position against the bed of the press.- Fig. 2 is a side view of theplaten in position for receiving the sheet.
The platen B- is supported by rockers O, which rest on rocker-seats K, and thus far is similar to the construction shown in my patent of November 9, 1869. I For controlling the movement of this rocking plat-en, I have usually employed a yielding spring-connecting device pivoted at the extremity of the rocker nearest the bed and to the frame of the press at the rear end of the rocker-seat, as shown in subsequent specifications, and in addition to such construction it has been my custom to use rigid arms projecting from the rockers, and provided with lugs, which, together with the rear ends of the rocker-seats, formed a position exactly parallel to the face of the bed during the time of producing the impression.
In the present case I do away with the complicated devices above mentioned, and use in connection with the rocker a simple rigid connecting-link, L, as shown in the drawings, Fig. 1, and which is at right angles to the face of the rockerseat when the platen is 011 or very near the impression. The toe of the rocker is flattened so as to slide on the rockerseat K as the impression is taken. The movement for the actual impression being slight, the change in position of the link L doesnot practically change the relative parallel positions of platen and bed. As the platen recedes from the face of the bed to receive the sheet to be printed or the article to beimpressed, themovement is at first practically a In Figs. 1 and 2 an ordinary crank and draw-bar construction is shown as the parts for directly giving motion to the platen, and
Serial No. 204,203. (No model.)
these are duplicated, one for each side of the press. The link L may be single, placed between the sides of the press; or two may be employed, one for each side.
It will be seen that during the impression three points-pin I, the pivot of link Lto the rocker, and the flattened toe of the rocker 1 govern the position of the platen, and that an accurate working of the press is secured. As the link L is at right angles to the plane of the rocker seat at the time of the impression, or
nearly so, and the pivot of link L, forming the attachment of the link to the rocker, forms the fulcrum between pin 1 and the flattened toe of the rocker at e, neither extreme of the rocker can be depressed or lifted, and theimpression must therefore be direct and accurate.
The devices applied to the rocker motion of the press may be used for either the bed or the platen, or for both, as eitherbed or platen may be made movable, or both may have motion, as the case may require.
All of the devices of the foregoing specification are applicable not only to presses for printing, but also to presses for embossing, stamping, cutting, and creasing, and other pressure machinery.
What I claim as my invention is 1. In a press having a bed or platen to which a rocking motion is given, the combination, with the rocker and its rocker-seat, of the connectinglink for controlling the movement of the rocker, the link being at right angles to the face of the rocker-seat, or nearly so, when in position for the impression.
2. The combination, with the rocking bed or platen, of the rocker and'its rocker-sea't, the controlling-link, and the impression drawbar, the link being pivoted to the parthaving the rocking motion at a point intermediate between the toe of the rocker and the connecting-pivot of the draw-bar.
3. The combination, with the impressioncrank F and the draw-bar, of the rocking bed or platen provided with the rocker and its rocker-seat, and the pivoted controllinglink, the link so connected to the rocker as to be deflected backward from a vertical position during the backward rolling movement of the rocker.-
In testimony whereof I affix my signature in presence of two witnesses.
Witnesses: MERRITT GALLY.
