WHIFFLETREE.

SPECIFICATION forming part of Letters Patent No. 306,988, dated October 21, 1884-.

Application filed May 15, 1884. (No model.)

reference marked thereon, which form a part ot' this specification.

lIhis invention relates to improvements in whiftletrees; and it consists in the construction hereinafter set forth, and pointed out in the claims.

In the accompanying drawings, Figure l is a plan view, and Fig. 2 is a detail sectional view.

A represents a rectangular bar ot' metal, which is provided at its end with a reduced screw-threaded portion, B, said bar forming a means for attachment of the connectinghooks C C, which represent cock eyes or hooks, which are provided with openings c of greater diameter than the serewthreaded portion of the bar A.

D represents angular metallic plates, which are `provided with openings d, through which pass the screwthreaded portions ofthe bar A. rlhese angular plates bear upon shoulders d, as shown in Fig. 2, and are held securely in place by a nut, E, against the outer face of which bears the perforated end of the cockeye C, which is in turn held in position by a nut, E.

Through the perforations e in the plates D pass the end links of a chain, F, the opposite ends of said chain passing through the eye G of the clevis-hook H.

By the construction herein set forth the flat portion of the rectangular bar A will be kept or held when in use, thus enabling me to elnploy a very light bar or spreader, and at the same time bracing the same by the chains. The hooks C C at the end of the bar are held rigidly to the same.

By means of the short chains F F, angleplates D, and elongated loop G on the clevishook H the bar is allowed a limited amount of play, but will be held in substantially a horizontal position and the ends of the bar prevented from being excessively depressed.

l. In combination with the rectangular bar A, having screw-threaded ends B, the anglepla-tes D, with connecting plates attached thereto, hooks C, and retaining-nuts, organized substantially as shown, for the purpose specitied.

2. In combination with the rectangular bar A, having screw-threaded ends B, bent plates D, chains F F, and hook H, with elongated loop G, the hooks attached to the end of the bar A, and nuts E E', for holding the plates D and hooks C rigidly upon the end of the bar, for the purpose speciied.

In testimony whereof I affix my signature in presence of two witnesses.
