. EXGLAND.

- HARNESS SHAFT TUG.

SPECIFICATION forming part of Letters Patent No. 309,529, dated December 23, 1884. Application filed February 9. 188 1. (No model.) Patented in England May 29, 1883, No. 2,659.

To aZZ whom it may concern.-

Be it known that I, STEPHEN llnwlinn DAYIES, a subject of the Queen of Great Brit. ain, residing at Liverpool, in the county of Lancaster, in the Kingdom of England, have invented certain new and useful Improvements in Shaft-Tugs, (for which I received Letters Patent in England, dated May 2), 1883, No. 2,659,) of which the following is a spccification.

My invention consists in a metallic shafttug formed of malleable cast-iron or other like tough metal, and constructed as hereinafter explained, whereby economy, strength, and neatness are secured, together with convenience in use and facility of repair,

In the accompanying drawings, Figure l. is a perspective view of my improved shaft-tug, and Fig. 2, a similar view or a slightly-modified form of the same, in which the shaft is entered. at the side, instead of passing the tug over the end of the shaft.

In the drawings A. is the metallic body of the tug; B, the strap; 0, thehuckle; l), thetong ue; E, pin for buckle, and F the inlaid lining, of leather or composition, upon which the shaft rests. An offset or guard, G, is formed on the interior of the tug, to hold the lining 1* in place.

II are the loops through which the lower end of the strap 13 is passed, and I is a leather lining secured to the metallic tug to prevent the latter from wearing the saddle, as clearly shown in. Figs. 1 and 2. The eye or hole for the shaft is preferably pear-shaped, as indicated in the drawings; but the lower portion upon which the shaft rests should be hen1ispherical, and is lined with leather or a replaceable lining, F, of metal or tough composition, riveted to the body of the tug, as shown.

The loops H may be cast in one piece with the" metallic tug, and one or more may be used, as is found necessary or desirable.

By the use of the double buckle herein described and shownthat is to say, a buckle having its tongue mounted upon a cross-bar intermediate between the ends of the buckleframe I am enabled to pass the strap 13 behind the tug and next to the saddle. Care must be taken, however, to see that the loops H are put so far forward as to avoid rubbing the saddle. The above arrangement enables me to have a part out out and a hinged coverpiece inserted, so that the shaft can be insert-ed from the side, instead of having to pass the loop or tug over the end of the shaft, as clearly shown in Fig. 2.

J is the hinged cover-piece, hinged to tag proper at K, while at the opposite end the piece J is provided with a recess, into which is fitted a sliding bolt, L, which is adapted to enter a hole or recess in the tug, and thus firmly keep the hinged portion J in place.

At the rear end of the bolt- L is a spiral spring, M, of sufficient strength to keep the bolt forward, and prevent its becoming undone by reason of any jar, while at the upper side of the bolt is a thumb-piece, N, bywhich the bolt may be retracted, and which projects through a slot, 1, in the upper face of the hinged or pivoted arm J, as shown in Fig. 2. By pushing the thumb-piece N back toward the pivot 01" the arm J, and thereby compressing spring M, the end of the bolt becomes clear of the hole or opening in the tug, and the hinged arm can be swung back on its pivot, and thus afford an opening through which the shaft can be inserted. The end of the bolt L can be beveled at the back, if desired, so as to close and fasten automatically when the hinged piece is brought back to normal position.

The tug as above constructed is simple, cheap, and durable, the lining F in the interior of the tug serving the purpose of a cushion to prevent any undue wear and disfigurement of the shafts, while the lining I on the outside of the tug prevents any similar trouble with the saddle or the strap.

Having thus described my invention,what I claim is.-

l. The combination,with a metal shaft-tug, of a buckle pivoted thereto, and having its tongue mounted upon a cross-bar intermediate the ends of the lmckle-frame, and aloop or bridge, H, placed at the bottom of the tug,

through which the back-band passes, substantially as described.

2. The combination, with a metal shaftfltug ice provided with a buckle pivoted thereto, and In testimony whereof I have signed my name having a middle crossbar to support and carry to this specification in the presence of two sub- 10 the buckle-tongue, of a hinged piece, J, openscribing witnesses.
