To aZZ whom, it may concern.-

Be it known that I, JOHN B. CROSBY, of Bonshaw, Queens county, Prince Edward Island, Dominion of Canada, have invented a certain new and useful Improvement in Shaft-Tugs for Harnesses, of which the following is a description sufficiently full, clear, and exact to enable any person skilled in the art or science to which said invention appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which Figure 1 is an elevation showing my improved tug in use; Fig. 2, a transverse sec tion on line or m in Fig. 1, and Fig. 3 perspective views illustrating details of construction.

Like letters of reference indicate corresponding parts in the different figures of the drawings.

My invention relates to a metallic shaft-tug for harness-saddles; and it consists in certain novel features, as hereinafter fully set forth and claimed, the object being to produce a simpler, cheaper, and more effective device of the character than is now in ordinary use.

The nature and operation of the improvement will be readily understood by all conversant with such matters from the following explanation.

In the drawings, A represents the shaft, B the girth-strap, O the breeching or holdback strap, and D the trace. -A bar I) is provided with a longitudinal slot cl. A movable link E is composed of a metallic barb, provided with a longitudinal slot d and a bent wire rod f, having its ends secured in said bar. This link has end loops g and a central side loop h. A strap j is secured in the loop 71 of the rod f, and is provided in its outer end with a buckle It for attaching it to the saddle-strap. The girth-strap B is secured to the inner side of the strap j and projects downward therefrom.

The breeching-strap O is secured in one end of the rod-loop f and the tug-strap or trace D T-shaped hook 13 projects vertically from the plate on, the head of said hook being arranged transversely on said plate.

My invention as thus described is espe-.

buckle. The horse being in position between the shafts, the bar I) is turned outward until its slot cl registers with the head of the hook p, which is passed therethrough and said bar turned back parallel with the shaft. The shafts are thus supported directly from the saddle in the same manner as when the ordinary circular tugs which inclose the shaft are used. The length of the slot cl permits sufficient longitudinal play to the shafts. The strain from the tug and holdback or breeching is borne directly by the tug and hook, thus enabling the animal to much more readily handle the load than when the ordinary trace and whiffletree are employed.

It will be seen that in light vehicles my improvement can readily be used to replace the common tug, as it does not interfere with the action of the ordinary breeching, trace, and breast-strap.

Havingthus explained my invention, what I claim is- 1. In a shaft-tug, the combination of an attaching-plate provided with a T-shaped stud, the top of which extends transversely of the shaft, a bar provided with a longitudinal slot adapted to receive said stud, and a loop secured to said bar to which the harness-straps are attached, substantially as described.

2. In a shaft-tug, the combination of a rectangular link having a longitudinal slotted bar on one side and a central loop at-its opposite side, and an attaching-plate provided with a headed stud engaging the slot of said bar.
