EDWIN E. PRATT, OF CHICAGO, ILLINOIS, ASSIGNOR TO A. N. KELLOGG NEWSPAPER COMPANY, OF SAME PLACE.
STEREOTYPE-PLATE HOLDER.
SPECIFICATION forming part of Letters Patent No. 311,524, dated February 3, 1885.
Application filed June 29, 1983. (No model.)
To all whom it may concern.-
Be it known that I, EDWIN E. PRATT, a citizen of the United States, residing in Chicago, in the county of Cook and State of 111inois, have invented a new and useful Improvement in Stereotype-Plate Holders, of which the following is a specification.
This invention relates to improved means whereby stereotype-plates not cast upon or made integral with or permanently attached to their supporting-blocks are secured to said blocks while in the form; and it consists in the novel features hereinafter set forth and claimed.
In the drawings which form a part of this specification, Figure 1 is an end View of a block and plate to which my invention has been applied, showing the springs ready to be forced into locking engagement; and Fig. 2 is a perspective view of the springs detached.
In said drawings, A represents the supporting-block, and B the stereotype-plate. C C
are flat metal springs, the upper ends of which, when unconfined, stand out from the block.
The points of the springs are bent at right angles toward the plate, so that when locked in the form the pressure of the colu1nn-rules will force said points'into the recesses bin the side edges of the plate. These springs should be let into the blocks both at the sides and bot tom, as indicated by dotted lines, but are otherwise unattached, so that they may be moved and removed at will. They are used in such number as the size of the plate requires, and automatically release the plate whenever the form is unlocked, thus permitting rapid changes of the matter being printed.
I claim- The combination, with the block and plate, of the unattached springs C C, passing under the block, and having the turned-over points adapted to be forced into the recesses in the plate, substantially as specified.
EDWIN E. PRATT.
