WHIFELETREE-HOOK.

SPECIFICATION forming part of Letters Patent No. 606,357, dated June 28, 1898. Application filed October 25, 1897. Serial No. 656 ,363. (No model.)

To all whom it may concern.:-

Be it known that I, HKAN OLSON, a citizen ofthe United States, and a resident of Seperville, in the county of Knox and State of Illinois, have invented certain new and useful Improvements in WhiiIletree-Hooks;and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled inthe art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification. i

My invention relates to whiflietree-hooks; and its object is to provide an improved construction of the same which may be slipped backward, so as to open the same for the insertion of the trace,and which is closed by the draft or tension of the trace.

The invention consists in the novel construction and combination of parts hereinafter fully described and claimed.

In the accompanying drawings, Figure 1 is a plan view showing a portion of awhifletree with my improved hook applied thereto. Fig. 2 is a horizontal section of the same. Fig. 3 is a similar view of a modification to be used with light vehicles. Fig. 4 is a similar View of another modification.

In the said drawings the reference-numeral 1 designates an ordinary whiflietree formed at the end with a rectangular slot 1a and with two holes 2, alined with each other and intersecting the openings ila at right angles Ithereto.

The numeral 4 designates the hook, comprising the curved portion or arm 5, having its end turned inwardly, forming a lug 5a, and the rectangular shank 6, provided with a slot 7. It will be seen that there is a space between said inwardly-turned end of the arm and the shank to allow a trace to be inserted. In the outer edge of the said shank, or that side farthest from the arm, is formed a recess 8 to receive a spring 9. The said shank is also extended backward toward the center of the whiiiletree, forming an arm 10, provided with an inwardly-extending lu g 1l, which engages with a hole l2 in the whiftletree.

The numeral 13 designates a pin passing through the holes 2 and the slot 7, and 14. a collar or ferrule on the endof the whiliietree.

In using the device the shank is inserted in the slot in the end of the whiftletree, with the lug 11 projecting into the hole 12. The

pin 13 is then passed through the holes 2 and wpulled out to close the hook.

the slot 7 inthe shank. To engage a trace with the hook, the latter is pushed backward, so as to uncover the space between the arm and shank. The end of the arm is then passed through the usual hole in the trace, and the draft upon the same by the horse will pull the hook forward, closing the space and preventing the trace from becoming disengaged. The slot in the shank permits of this sliding movement ofthe hook, while the spring 9 prevents rattling of the hook. By reason of the extension or arm of the shank and the lug the strain to a great extent is taken from the pin 13. In light vehicles,however, the said arm and lug may be dispensed with, as in Fig. 3.

In the modification shown in Fig. 4 the end of the shank is formed with a head 15, which abuts against the Whiflletree when the arm is In this case no strain comes upon the pin, which simply holds the hook in the opening or slot in the whiffletree, the entire strain being borne by the head.

It is obvious that my invention maybe used for other purposes besides Whifiletree-hooks.

Having `thus fully described my invention, what I claim is- 1. The combination with a whifiietree hav ing a slot in the end and two intersecting alined holes and the collar or ferrule, of the hook comprising the curved arm having an inwardly-extending lug at the end, the shank integral with said arm formed with a horizonn tal slot and with a recess in its rear side, the pin passing through said slot, and the spring seated in said recess, substantially as described.

2. The combination ,with the whilizletree having a slot in the end and two intersecting alined holes and the collar or ferrule, of the hook comprising the curved arm having an inwardly-extending lug at the end, the integral shank formed with a horizontal slot and with a recess in the rear side, the pin passing through said slot, the spring seated in said recess, and the head at the end of the shank,

`substantially as described.

In testimonythat I claim the foregoing as my own I have hereunto affixed my signature Witnesses:

S. A. TORNQUIsT, W. H. MATHUS.'
