UNITED STATES PATENT QFFTQE.
E. A. PALMER AND A. I. SIMMONS, OF OLAYVILLE, NEW YORK.
Specification of Letters Patent No. 9,252, dated September '7, 1852.
To all whom it may concern:
Be it known that we, EDWIN A. PALMER and ADOLPHUS I. SIMMONS, of Clayville, in the county of Oneida and State of New York, have invented a new and Improved Hook for Whiffletrees; and we do hereby declare that the following is a full and exact description of the construction and operation of the same, reference being had to the accompanying drawings, making a part of this specification, in which Figure 1 is a perspective view, Fig. 2 a longitudinal elevation, and Fig. 3 a transverse section.
A, Fig. 1 is the body of the hook; B, the cylinder or head; C, the hook; D, the slide catch, and E, the cap.
At A, Fig. 2, (like letters refer to like parts,) the front part, including the hook, being removed, is seen the hollow body, which is cast in the form of a ferrule, to be driven onto the end of the whifiletree.
B, is the head which is also hollow, and turns on the stem or shaft F, which is a continuation of the main body A.
D, is the slide, which moves in the slot seen at a, and slips by a projection at e (not seen) when the hook is closed, as in Fig. 1, and prevents its opening.
G, is a spiral spring which operates in such a manner as to turn the head back to its place when opened to receive the trace, and also to keep the slide D, in its place, as shown in Fig. 2.
E, is a cap which is riveted upon the end of shaft F, to hold the whole together.
Fig. 3 is a transverse section of the head, B being the head; F, the shaft upon which it turns; G, the spring, and D the slide, showing the Wings (23, d, which prevent the slide being cramped in its operation by the action of the spring, one end of which enters the shaft at e, and the other end the slide.
To hook the trace, the slide D, is pushed toward the outer end of the whitfietree, as shown by the arrow No. 1, which passes it beyond the projection at 0. The head is turned in the direction indicated by arrow No. 2, which opens the hook at the joint, f, Fig. 1. The trace being hooked the hand is removed and the spring G, closes the book by turning the head back, and also throws the slide D, to its place, when no action of the trace can open the hook.
WVhat we claim as our invention, and desire to secure by Letters Patent, is
The head turning upon the shaft to close the hook, the sliding catch to prevent its opening, and the spring within the head, acting upon them, the whole combined and operating substantially in the manner speci- EDWIN A. PALMER. ADOLPHUS I. SIMMONS.
