Description
UNITED STATES PATENT OEEICE.
GEORGE C. TAE-T, OE WORCESTER, MASSACHUSETTS, ASSIGNOR TO THOMAS H. DODGE, OF SAME PLACE.
IMPROVEMENT IN COPYING-PRESSES.
Specification forming` part of Letters Patent No. 43,266, dated June 2l, 1864.
To all whom it may concern Be it known that I, GEORGE C. TAET, of
the city and county ot' Worcester, and State of Massachusetts, have invented certain new and useful Improvements in Letter-Copying Presses; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, which form a part of this specification, and in which- Figure 1 represents a perspective view of my improved press, and Fig. 2 represents a longitudinal section of the press.
In the drawings, A represents the `bedpiece; B,the platen, and() the arch-piece. The bed and arch-piece are fastened together and retained in their proper and relative positions by means of bolts D D and nuts D D. To the center of the platen B is fastened the screwspindle E, which works in a female screw cut in the thimble-piece F, which, in
. this instance, has three shoulders, a, b, and o.
The first two work up against corresponding parts in the archpiece C, while the latter re ceives and supports the handle-piece G, which is to be made fast to thimble-piece E in any wellknown manner. In the drawings it is represen ted as fastened by means of a screw, H, fastened to the cap or head I. The screw H Works into a thread cnt in the upper end of the tliirnble-piece F, and therebydraws the shoulder c of the latter up tight against the under side of the handle-piece G, while cap I bears equally firm against the top of the handle-piece G. The platen has projections d d, which work in proper grooves in 'the side supports, J J. It will be seen that when the handle is turned the thimble-piece will be revolved, thereby either raising or loweringr the platen, as may be desired. By the use of the thimble-piece F, when the thread becomes worn out or comes to repairs, a new thimble-piece can be very cheaply inserted. Again, the thimble can be made of malleable iron, and thereby be capable of resisting great strain without breaking its thread, even though quite tine. Still,again,tl1e thread'can be cut rather Inore conveniently than in a large piece, like the arch.
Having described my improved press, what I claim as my invention, and desire to secure by Letters Patent, is-
The combination of the handle piece G and and thiinble-piece F with the archfpiece C and screw-spindle E, substantially as set forth.
