Application filed October 26, 5.968. serial No. -l=52,612.

B it known that I, BENJAMIN C. Stranrann, citizen of the United States, residing at Chicago, county of Cook, andState of lliinois, have invented certain new and useful Improvements in Sliaft-Tugs, of which the following is a specification.

My invention relatesto improvements in shaft-tugs or thin-holders, and has for its object to provide a new and improved article of this character which shall be simple and inexpensive. in manufacture, neat and attractive in appearance, and durable in use.

A-furth r object of the invention is to provide an elastic buffer to deaden the concussion between the shaft or thill and the upper portion of the shaft-tug or thilLholder.

il ith these, and other objects in view, the invention consists in certain novel features in construction and combination. of parts which will be hereinafter more fully described and finally pointed out in the claims hereto appended; it being understood that various slight changes, such as in the form,

' proportions, and nnnor details of construction may be resorted to without departing ,iirorn the spirit or scope of the invention.

Referring to the accompanying drawings forming a part of this specification wherein like characters of reference denote similar parts throughout the several views: Figure l is a perspective view of my improved shaf tng or thill-holdcr, Fig. 2 is a vertical cen-.

tral sectional view thereof, with portions thcreot broken away, F1 3 1s a cross sectional view taken on the ine m-,w of Fig. 1

with the lower portion thereof broken away, and is a vertical central section of the lower portion of the shaft-tug or thill'. holder.

carrying outthe aim of my invention, It employ a loop-shaped rubber body 1 having the lower end 2 extending beyond the general outer peripheral line to fol-men ear or projection. The uper end of the body 1 is formed with an integral. depending ortion 3 adapted to act as a buffer for the s iaft or thill in striking thereagainst.

The inner face of the loop body portion 1 is provided with the approximately U- shaped metallic bushing e which has its lower portion provided with a pair of op positcly disposed depending ears 5, each of ovided with an opening 6 adaptwith the opening '7 in the end L, clearly in Fig. l. The openings 6 are adapted to receive the ends 8 of the girth loop 9, which ends 8. are adapted to be sprung into position. The bar 10 of the girth loop 9 is adapted to carry the girth-strap 11 as shown in Fig. 1. The upper free ends ofthe bushing 4- are adapted to snugly engage the outer face of the butler 3, as clearly shown in Figs. 1 and 2. It- Will be observed that the bushing 4 has its outer face 13 fiat and its inner or wearing face 14: convex, as clearly shown in Fig. 3, so as to allow a rocking'inovement thereof upon the shaft or thill.

The upper portion of the body 1, it Will be seen, is provided with a recess 15 adapted to receive the cross-bar 16 of the buckle 17,

and that the recess 15 is enlarged as at 18 so as to allow for a rocking movement of the tongue 19, the lower end 20 of which encircles the crossbar 16, as clearly shown in Fig.4.

In order to hold the cross-bar 16 of the buckle 17 in the recess 15, I employ a strap 20 of any suitable material and of a sha e to correspond with the upper portion 0 the rubber body 1, which strap 20 is provided with a slotted opening 21 through-which the tongue 19 is adapted to pass. The strap 20 1S secured to the rubber body portion 1 which is recessed as at 22 to receive the strap,

and is held in place by means of any suitbushing l to which it adheres, and then after the same has been taken out of the mold, I apply the several parts consisting of the girthdoop 9, the buckle 17 and the strap 20.

Having described my invention what I claim as new, and desire to secure by Letters Patent, is:

l. A shaft tug c niprisinga rubber body portion substantial y annular in form, the upper end of said body portion being inwardly'curvcd forming a depending buffer and a recess in the upper edge, a substantially flat il-shapcd bushing arranged within said body and extending around thesanie fr one side of buller to the other and from face to thereof and a buckle havmold the rubber body 1 around the metallic ing its cross bar arranged in said recess, substantially as describe 2. A shaft tug comprising a rubber annular body portion, the upper end of said body portion being inwardly curved forming a depending buffer and a recess in them per edge to receive the cross bar of a buc e, a

. U-shaped reinforcing bushing arranged Within said body and extending around the same from one. side of said bufler to the other, a strap extending over the upper end of said body portion and having its ends' overlapping the adjacent ends of thebushsaid recess, substantia ing with the body ortion interposed between the same, an fastening means ex- 5 tending through the adjacent ends of said bushing and said strapysadd strap sganning 1y as desc'mbe In testimony whereof I have signed my name to this specification-in the presence of 20 two subscribing witnesses.
