SPECIFICATION forming part of Letters Patent No. 455,259, dated June 30, 1891.

Application tiled February 24, 1891. Serial No. 382,665. (No model.)

To @ZZ whom it 711.51.11 concern.-

Beitknown that I, PATRICK HENRY THoMP- SON, a citizen of the United States, anda resident of Bluffton, in the county of Clay and State of Georgia, have invented certain new and useful Improvements in Vhffletree- Hooks; and I do hereby declare the following to be a 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 letters and iigures of reference marked thereon, which form a part of this specification.

This invention relates to whiftletree-hooks, having for its object the construction of an inexpensive device which is capable of easy and convenient operation to attach and release the traces or tugs to and from a vehicle, the details of all which will be hereinafter fully dedescribed.

In the accompanying drawings, Figure l is a plan of the device attached to one end of a whiflietree, showing the parts in the positions they would assume when the trace. was attached, said trace, however, not being shown. Fig. 2 is a back view of the parts shown in Fig. l. Fig. 3 is a perspective view of the key and handle thereof. Figa is a plan view of the notched bars, showing the construction thereof in which it is provided with a hook for attachment to the trace. Fig. 5 is a plan of the thimble with the key and bar removed, showing the form of the key-seat therein. Fig. 6 is a sectional view withv the bar and key in place, said key being turned to allow the removal of said bar.

Like reference-marks are employed in the designation of corresponding elementsin all the views.

The whiiiictree A may be of any form, as may also the socket B, provided they are capable of containing` the several elements. The construction of socket shown is a tapering piece with a recess to slip over the reduced end of the whiffiet-ree, the end of said socket carrying the usual elliptical button for use in case of accident, said button also forming a strengthening element in the endof the socket. Through the extension of the socket beyond the end of the reduced portion mentioned is a transverse slot b, preferably rectangular in form. Into this said slot or recess Vb the bar b will enter, said bar being` providedwith a hook b2 or other means for attachment thereof to the trace, such as a snaphook, loop, or rivets. Notches b3 are cut into the edges of said bar, and maybe of any number desired, as the bar b will be of sufficient length to slide in the recess b to adjust the length of traces from whiflietree to hames. At right angles to and cutting partially into the said slot b is aholeb4, which is of such shape as will allow the half-round pin c to revolve therein, which motion should be limited by suitable construction, for which purpose, as shown, the hole b4 is made to comprise only about three-fourths of a circle, which, leaving a projection b5, has the advantage of simplicity, as the hole maybe cast in the socket, and also provides a bearing-pointfor the pin c at a right angle to the line of strain when the vehicle is being drawn, which will prevent the bending of the pin c, and said pin may be made much smaller. The pin cturns into one of the notches b3, as best shown in Fig. (i. In order that the pin c may not be by any jar turned around or moved from its place,l a lip c is formed onfone end, operating to prevent its withdrawal from the hole when turned in the position shown in Fig. l, and the handle c2 is secured to the upper end and contacts, when in the position shown in Fig. l, forcibly with the metal of the socket, and by said contact causing sufficient friction to prevent the turning of said pin c within the hole b4, the lip c preventing'v the pin from rising in the hole and relieving said frictional contact. The lever c2 may be provided with a hole or other means for the attachment of a cord or chain and the device so be used as a horse-detacher.

Having thus described my invention, what l claim as new, and desire to secure by Letters Patent of the United States, is-

l. In a device of the class specified, the combination of a whifetree slotted near its end with horizontal and vertical slots,the vertical slot extending half its diameter into the horizontal slot and having a shape of approximately three-quarters of a circle, the notched hook carried in the horizontal slot, and the se1nicircular-shaped key seated in the vertical slot, substantially as described.

2. In a device of the class specified, the whiletree having a slot transversely cut in its end, the bar having means for the attachment of the trace, and a notched edge, and a round pin seated in said Whifetree and having the portion near the bar halved, forming corners, substantially as shown, and adapted to he partially revolved in its seat to such a position as will turn one of its corners into one of the notches in said bar, all combined, arranged, and operating substantially as shown and described, and for the purpose specified.

In a device of the class specified, a mefallic head having a socket to fit on the end of a whiiletree and a slot to' receive the end of a trace, and a hole, of a form coinprlsing three-fourths of a circle, in said head transversely to said slot, and a half-round pin pro-
