UNITED STATES PATENT OrFre-E.
MARSHALL FINLEY, OF OANANDAIGUA, NET YORK.
IMPROVED DAGUERREOTYP-E-PLATE HOLDER.
Specification forming part of Letters Patent N o. 10,093, dated October 4, 1853.
To @ZZ zuwnz t may concern.-
Be it known that I, MARSHALL F1NLEv,ot Canandaigua, in the county of Ontario and State of New York, have invented certain new and useful Improvements in Apparatus called the Daguerreotype-Plate I'Iolderfand I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, which form part of this specification, in which- Figure l represents a perspective view showing Jdie block or holder A, its beveled corners b, the pressing-screws c, the heads of which are made dishing or concave, and the plate in position with its four several corners clasping their corresponding screwheads. Fig. 2 represents a vertical longitudinal section of the same with the plate removed for the purpose of showing more clearly its construction and operation.
To enable others skilled in the artA to make and use myimproved plateholder, Iwill proceed to describe in detail the construction and operation of the same, which consists of a base or platform A, of suitable size and thickness, and usually in the form of a parallelogram. The four corners of this platform are beveled off, forming an oblong` Octagon, as represented in Fig. l. Into two of these corners I insert in mortises of the required depth spiral springs e e, which constantl7 tend to force the pressers outward, as shown in Fig. 2. On the shank of each of these pressers is formed a wrist r, having on its end a head or cap i, the face of which is of the same size and is immediately in contact with the spring e. To prevent the spring from forcingl the presser entirely out of its proper position, I insert through the platform A a key or pin in such manner as to permit the presser to move back and forth the required distance, but to prevent, by coming in contact with the shoulder formed by the cap i, all possibility of its becoming deranged. The head CZ of the presser may be more or less dishing or concave to suit dilferent constructors, as represented in dotted lines, the object of which is to receive the corners ot' the plate B, which are necessarily bent or formed into the shape of hooks, grasping rmly the heads of the pressers or sliding screws, as shown in Fig. l. Into the ltwo opposite corners of the block or holder I insert adjustable screws a, with concave heads corresponding with their opposites, which admit of being set out or in to accommodate any variety in the size of the plate. In the center and on the under side of the platform is Iit ted a square stock or handle e, which is inserted into a socket prepared to receive it, for the purpose of holding the platform firmly while the plate is being bul'fed, or grasped by the hand in bufngthe plate upon a wheel.
I do not claim holding daguerreotype-plates to be buffed by the outward pressure of spiy ral springs against the turned edges of the plate; but
That I do claim as new, and desire to cure by Letters Patent, is-
Constructing a'sold daguerreotype plate holder or block having fastenings at each corner made by spiral springs, in combination with tightening-bolts having concave heads, into which the bent or turned corners of the plate to be buffed are hooked so as to admit of a uniform bufiiig, as herein set forth.
MARSHALL FINLEY. fitnessesz JAMES G. MITCHELL, SIMEON K.. OUTLEE.
