WHIFFLETREE-HOOK.

srncrrrcnrron forming part ofLetters Patent No. 565,688, dated August 11, 1896. v

Application filed May 9,1896. Serial No. 590,903. (No model.)

invented certain new and useful Improvements in Whiffletree-Hooks and I do hereby declare that the following is a full, clear, and

exact description of the invention, which will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings and the letters of reference marked thereon, which form part of this specification.

The object of this invention is to provide a whiflletree-iron which may be readily attached to the whiffletree, said iron being formed in two parts, one of which is rigidly attached to the whiffletree, the other of which is movably attached to the end of the first part, being so arranged that when the two parts are brought together they form a closed loop or hook for the trace or tug, the movable piece being so constructed that it may be readily detached from the fixedportion, so that should the movable part be broken it may be thrown away and replaced by a new one, while the fixed part, not being liable to breakage, will not require to be removed or replaced, thus securing an economy to the user.

My improved whiffletree-iron is simple in construction, easy to operate, and economical in use.

Referring now to the drawings, Figures 1 and 2 are side elevations of my improved whiffletree-iron, Fig. 1 showing the iron closed,

and Fig. 2 showing the iron open. Fig. 3 is a front view of the iron in a vertical position, showing it open. Fig. 4; is a similar view of the iron, showing the same closed. Fig. 5 is an end view of the iron in an open position. Fig. 6 is a perspective view of the two parts detached and slightly removed from each other.

The letter A indicates the fixed part of my whiftletree-iron, hereinafter called the ferrule. This ferrule A is provided with a semihook A.

The letter B indicates the movable part, hereinafter called the hook.

The hook B is removably attached to the ferrule A bymeans of the pin a, having the cross-head a, and the corresponding opening 5, formed in the hook B, these parts being so arranged that the hook B may be removed from the pin a and the cross-head a when the hook portion A of the ferrule A and the hook portion B of the hook B are at approximately right angles to each other, while, when the whiffietree-hook is closed, the crosshead a will be at right angles to the opening I), and the hook B will be retained upon the pin a of the ferrule A by said cross-head a.

The hook B is provided with a hook portion B, which, as shown in Fig. 1, is of such dimensions that it will fit snugly inside of the hook portion A of the ferrule A when my whiflietree-iron is closed, and as the tug or trace is attached to this hook portion B the latter takes nearly all the strain and consequently is the only part liable to breakage when the whiffletree-hook is in use.

The hook portion A of the ferrule A, as the two parts fit snugly together, takes a portion of the strain and serves as a strengthening piece or brace to the hook portion B when in use, but is not so liable to breakage. The hook B is provided with two arms I), one upon each side of said hook-piece. These arms embrace the end of the ferrule A when the hook B is in position upon said ferrule A, as is shownin the drawings, and in connection with the stop a upon the ferrule A serve to arrest the motion of the hook B as it is turned upon the pin a and prevent the hook from swinging or turning too far upon said pin, thus limiting the extent of the rotation of the hook B upon thesaid pin a.

It will be obvious that the hook B, should it become broken, may be removed from the pin a of the ferrule A and thrown away and a new piece or hook B put on said ferrule instead thereof, for as but little strain comes upon the hook portion A it is not liable to be easily broken, and the ferrule part A of my improved hook thus becomes a permanent fixture upon the whiffletree.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A whifiletree-hook consisting of a ferrule A, having a hook portion A, a pin a, with a cross-head a, in combination with the hook 4. In combination the ferrule having the rigid hook A, the hook B swiveled t0 the ferrule and being of smaller size to fit inside the hook A, the detachable connection between the swiveled hook and the ferrule and the stop for limiting the movement of the swiveled hook, substantially as described.

In witness whereof I have hereunto set my hand in presence of two Witnesses.

JONAS OLSEN.
