JOHN FLOYD GRAVES, OF ELLSWORTH, MINNESOTA.

wHaFFLETREE-HOOK.

SPECIFICATION forming part of Letters Patent No. 488,391, dated December 20, 1892.

Application led April 13, 1892. Serial No. 42 9.024. (No model.)

To a/ZZ whom t may concern:

Be it known that I, JOHN FLOYD GRAVES, a citizen of the United States, residing at Ellsworth, in the county of Nobles and State of Minnesota, have invented certain new and useful Improvements in Whiffletree-Clips; 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.

This invention relates to Whiflietree clips.

The object of the invention is to provide a fastening or clip that will admit of the trace being readily secured to and removed from the whiffletree, and which will be efcient and convenient of manipulation.

The improvement consists of the novel features and the peculiar construction and combination of the parts which will be hereinafter more fully described and claimed, and which are shown in the annexed drawings, in which;

Figure l is a perspective view of the end of a whiftletree having my improved clip applied thereto. Fig. 2 is a longitudinal section of the outer end of the clip. Fig. 3 is an inner View of the hollow plug which is inserted in the thirnble, the cap plate being removed, and showing the operation of the headed pin and the retaining spring by dotted lines. Fig. l is a detail view of a modiiication, parts being broken away to the-bet ter show the details of construction. Fig. 5 is a section on the line 5 5 of Fig. 4 looking in the direction of the arrow.

The clip comprises' essentially a hollow plug A having an oval shaped projection d eccentrically disposed on its outer end, and having a bore through said projection and the closed end of the plug to receive the pin B which is adapted to turn therein. This pin is provided at its inner end with a flat side head b which is adapted to be engaged by one or more iiat springs O which are extended across the space between and secured at their ends to the sides of the plug. The spring or springs C serve to hold the pin B at the required adjustment by engaging with the flat sides of the head ZJ, and have their ends slipped in grooves or slots e in the side of the said plug. The cap plate E secured to the inner end of the pin B, preferably by being riveted to or screwed upon a short pro j ection integral therewith, protects the spring or springs from injury and retains them in position. The turn button F securedA to the outer end of the pin B is adapted to be turn ed parallel With the major axis of the proj ection o. or set crosswise thereof, being held in either position by the spring or springs engaging with the iiat sided head b.

The plug constructed as shown in Fig. 4 is designed to be slipped on the end of awhiletree, and when made as shown in the remaining figures is designed to be fitted in a thimble D which is preferably tapering and adapted to be slipped on the end of a whiffietree.

When applying or removing the trace from the clips, the turn-button is set parallel with the projection a, and when the trace is in position on the said projection d the turn loutton is set crosswise to prevent the trace slipping off.

Having thus described my invention, what l claim, and desire to secure by Letters Patent is;

l. A whiffletree clip consisting of a plug having a projection at one end to receive the trace, a pin journaled in the said plug and formed with a fiat sided head at its inner end, and provided with a turn button at its outer end, and a ilat spring adapted to press laterally on the fiat side of said head to retain the said pin and turn button in proper position, substantially as and for the purpose set forth.

2. A whiftletree clip comprising a hollow plug having a projection at the closed end to receive a trace, a pin journaled in the said closed end of the plug and having a fiat sided head at its inner end, and having a turn button at its outer end, a fiat spring having its ends let into the sides of the plug, and a cap plate secured to the said pin and adapted to protect and retain the said, spring in place, substantially as described.

3. The herein described whiftletree clip conrprising a hollow plug having a projection at the closed end to receive a trace, a pin jour- IOO naled in the said closed end of the plug and the latter from longitudinal displacement having a Hat sided head at its inner endend substantially as speeied. 1o having a turn button at its outer end, asprng In testimony whereof Iafx my signature in having its ends let into the sides of the plug presence of two Witnesses.

and adapt-ed to act on the flat sides of the JOHN FLOYD GRAVES. said head, a cap plate secured t0 the inner /Vitnesses:

end of Jche pin, and a thimble embracing the CHARLES M. CRANDALL,

plug and the ends of the Hat spring to hold J. H. MCROBERT.
