WHIFFLETREE-HOOK.

SPECIFICATION forming part of Letters Patent No. 472,491, dated April 5, 1892.

Application filed May '7, 1891. Serial No. 391,857. (No model.)

To all whom it may concern:

Be it known that I, THOMAS ANDREss, a citizen of the United States, residing at Pittsville, in the county of Wood and State of Wisconsin, have invented certain new and useful Improvements in Tug-Locks for WVhiffletree- Hooks; and I do declare the following to bea full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

My invention has relation to improvements in tug-locks for whiffletree-hooks.

The object had in view is to provide a simple and inexpensive device for preventing the disengagement of the cockeye or tug from the whiffletree-hook; and the invention consists in the improved construction and combi- V nation of parts, as hereinafter more fully set forth and described.

In the accompanying drawings, Figure l is a perspective view showing the device attached to a whiftletree. Fig. 2 is a perspective view showing the whiffletree-hook with my improved lug ready for insertion thereon, and Fig. 3 is a transverse section through the hook and lug when the latter is applied to the hook.

Like letters of reference refer to like parts throughout the several views.

Referring to the drawings, the letter A indicates one end of a whiffletree, B the tracehook applied thereto and preferably provided with a groove 1) in the end thereof, and C indicates the cockeye.

The improved lug for insertion upon the end of the whiffletree-hook I have indicated by the letter D. This lug has its upper surface'rounded, as indicated at d, and its inner edge straight to form a shoulder d. The inner lower portion is formed with an integral collar d said collar provided upon its inner surface with a dovetail tenon d and upon its outer lower surface with a shoulder 61 in line with the dovetail te non.

Fig. 3 illustrates the mode of attaching the lug to the ordinary form of hook, which consists in filing the slight groove bin the end of the hook and then passing the collar over said end until thedovetail tenon fully registers with the groove. The lug may be madeof malleable iron, so that it can be forced securely into the groove by hammering the parts together. This arrangement presents the advantage of enabling me to place the lug upon the market as an improved article of manufacture to be applied to any hook. It is obvious, also, that the necessity of filing a groove in the hook may be dispensed with, inasmuch as the lug being of malleable iron the collar 61 may be hammered so as to embrace the hook closely and retain its position thereon.

By my improvement it will be seen that I present a device for the ready attachment or detachment of the cockeye and one in which the danger of said cockeye becoming unhooked when in use is effectually guarded against.

When a chain is employed on the end of the tug, the lug is to be made of sufficient size to nearly fill a link of the chain.

In coupling the trace all that is necessary to be done is simply to turn the cockeye to a transverse position and then pass it over the lug D upon the rearwardly-bent end of the hook, the shoulders of said lug beingjust sufficient to fill the space of the cockeye and admit of the insertion thereof. The cockeye will now assume the position illustrated in Fig. 1, and when the draft upon the trace is relieved and said trace becomes slack the weight of hook B naturally throws the same downward, and with this downward movement the cockeye is carried therewith, so that the upper part of said cockeye will rest upon hook B. If now the cockeye should Work around to a position transverse to that shown in Fig. l, the shoulder d of the lug will of course prevent the working off of the cockeye, inasmuch as said shoulder will contact with the upper portion thereof and act as a stop..

It is obvious that in order to remove the cockeye the same is required to be turned accurately and evenly. In any accidental movement, therefore, of the cockeye when the trace is slack, as just described, it would hardly be possible for the eye to be removed on account of the impediment offered by the shoulder d, assisted by the lower shoulder (1 Having thus described my invention, what I tion provided with a rounded edge terminating in a square shoulder, substantially as set forth.

In testimony whereof I affix my signaturein presence of two Witnesses.
