T. WIVTMER. Sister Hunks.

ToBrAs WITMEE, oF BUFFALO, NEW YORK, AssIGNoE oF ONE-HALF Hrs EIGHT To DAVID EANsoM, oF sAME PLAGE.
IMPRVEMENT lN SISTER-HOOKS.
Specification forming part of Letters Patent No. 154,360, dated August 25, 1874; application filed Ju y e, 1874.
To all whom it may concern Be it known that I, IOBIAs WITMER, of
Bualo, in the county of Erie and State of N ew York, have invented an Improvement in Sister-Hooks, of which the following is a specilication:
My invention consists in constructing and providing sister-hooks, used on my tire-escapes and trucks and ladders, and in the rigging of vessels, and for other purposes, with elastic bands, or rings, or ties, passing around the shanks-of the hooks, so as to keep the two parts of the hooks together, to prevent them from unclasping when the rope orA chain is slacked up, but, by the elasticity of the band or ring, allow it to he unhooked without removing the tie or band.
A is the thimble, to which the rope is attached, and protects the rope from chafing in. the ordinary Way, and is not claimed as new. B B are the two parts of the hook, clasping inversely together, forming a strong and substantial hook, comm only called a sister-hook,7 the form of which is not claimed as new. C is an elastic band, which, by its elasticity, will yadmit the hooks to beiseparated in hooking on the object to be fastened to, but which will keep them pressed together, and prevent unhooking when the rope or chain gets slack.
It will readily be seen thatby my improved elastic tie or band G, as described, the value of the apparatus vis very much enhanced, rendering its use much more convenient and safe than in the ordinary way.
When the ordinary tie or mousing is used much inconvenience is experienced in tying and untying, and without a tie or band the hooks are unsafe, being liable to be unhooked.
I do not claim the hooks formed thus, nor the tie or mousing, when made of inelastic substance, nor the elastic band or tie when used without the hooks, theseV being old; and do not confine myself to the particular materialv Vto secure ny Letters Patent, is
The elastic band C, in combination with the i hooks B B', for the purposes set forth.
TOBIAS WITMER.
