.MODE 0F PERATING THE FEED TABLES OE PRINTING PRESSES.
UNITED sTATEs PATENT oE'EIoE `GEORGEILITTLE, or UTIoA, NEW YORK.
MODE 0F OPERATING THE FEED-TABLES OF PRINTING-PRESSES.
Specification of Letters Patent No. 10,827, dated April 25, 1854.
To all whom z't may concern Be it known that I, GEORGE LiTTLE, of Utica, Oneida county, in the State of New York, have invented a new and Improved Mode of Feeding Paper to Printing- Presses; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings and to the letters of reference marked thereon.
The nature of 1ny invention consists in applying to one or both sides of the feed table a ratchet wheel working on a screw attached to one end of a connecting rod, the other end of said connecting rod being attached to an arm or crank having a series of holes in the saine so as to allow a ready means for adjusting the table upon which the paper to be printed is placed, the ratchet wheel being kept in mo-tion by means of a pin inserted and projecting from one end of the hollow cylinder or roller, thereby causing said table to rise as the sheets of paper are being removed to be printed. I also attach two guides faced with india rubber to the table in such a way that the same presses the mass of paper by its edges in order to prevent by its resistance more than one sheet of paper from being carried to the press during the operation of printing.
To enable others skilled in the art to inake and use my invention I will proceed to describe its construction and operation.
Figure l, shows a side View of the feed cylinder or roller R, and the table with its guides I-I, the ratchet wheel, screw, and arm or crank. Attached toA the same. Figs. 2, and 3 are sections of the same, A, Fig. 1, a pin projecting from the end of the feed cylinder, which said pin works into the ratchet wheel C, and carries the same around one tooth orrnore `during each revolution of the cylinder in the direction of the arrow shown above the pin. The ratchet during its rotation works the screw so as to force out the rod B, in the direction of the arrow and with it the arm or crank E, at tached to the center of the table, thereby causing said table to raise its end L, the
thickness of a sheet of paper at each operation of the press. If the paper be of a thick nature the pin G, attached to the chain is to be withdrawn from the hole at E and the rod secured a lio-le or two lower, so as to shorten the action of the arm or crank, which will cause the table to raise faster. On the contrary, the thinner the paper is, the longer must be the arm or crank. Said rod has a portion of its screw turned off at F, so that when the table is raised to its full extent and all the paper printed the ratchet will work on said smooth part at F only, thereby preventing the frame D, or the arm or crank from being broken or injured; the frame D, to be jointed at L, L, to allow for the rise and fall of t-he rod B. When it is desired to reset the table for operating, the rod B, with the ratchet, is to be lifted out of the frame D, and said ratchet to be screwed on to the rod again a. sufficient distance. This will depend entirely as to the quantity of paper that may be placed upon the table. I prefer the top sheet of paper to be on all occasions about one half an inch from the surface of the roller or cylinder.
Fig. 2, shows the end of the cylinder or roller A, A, with the pin projecting and in the act of passing' the ratchet C C, around D D, shows the ratchet frame with the upper part of the bearing left open for the more ready means of lifting out the ratchet and screw for adjusting the same. A spring or catch may be used if necessary in order to prevent the ratchet from having a tendency to move around more teeth than may be desired, as shown at E E.
Fig. 3, shows the mode I prefer of fixing theindia rubber to the guides H, H, and H Fig. l. The short black lines with the arrows between represent grooves with the rubber inserted therein and projecting about one quarter of an inch more or less, so that the edges of the paper may slightly curve between the same and thereby ofler a better resistance to the taking of more than one sheet' at a time inthe direction of -the arrows than would be oiiered'by Valjplain surface only. The said guides may if dei sired be made to adjust for different size sheets of paper by the aid of pins or screws shown at K, K, said pins or screws to fit in grooves in the sides of the table and be 5 secured with screw nuts.
What I Claim as my invention and desire to secure by Letters Patent is- The mode substantially as herein described for operating the feed tables of printing presses together With the guides 10 composed of india rubber or other suitable resisting material.
