VEHICLE-SHAFT.

SPECIFICATION forming part of Letters Patent No. 504,783, dated September 12, 1893.

Application filed April 21, 1892.

To aZZ whom it may concern.-

Be it known that I, ISRAEL HOGELAND, a citizen of the United States, residing at Ohicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Vehicle-Shafts, of which the following is a specification.

My invention relates to the construction of the coupling-means for the two shafts, my object, in this particular, being to provide for compactness, usefulness, novelty and economy, a combined shaft-coupling and tracehook device; and it also relates to the construction of a hold-back whereby simplicity and effectiveness are attained.

Referring to the accompanying drawings Figure 1 is a plan view of the shafts provided with my improvements. Fig. 2 is a view of the same in side elevation. Fig. 3 shows my improved coupling in longitudinal section, somewhat enlarged over the scale observed in the preceding figures, and applied to a shaft and one end of the cross-bar, both of which are shown broken. Fig. 4 is a view in side elevation of my improved hold-back applied to a broken section of a shaft. Fig. 5 is a view in end elevation of the hold-back. Fig. 6 is a front view of the coupling as illustrated in Fig. 3.

A,A denote apair of vehicle-shafts or thills, which may be, and preferably are, formed of tubular metal, though my improvements may be used with advantage on wooden shafts.

B is the crosspiece for connecting the two shafts near their rear ends. The connection is made through the medium of two like couplings 0, each formed of a single casting in the shape, or approximate shape, of an L, having a bore q, to slip it over a shaft A, on which it is secured, as by a pin a; a bore 19, extending at a right angle to the bore q to receive one end of the cross-piece B, fastened, as'by a pin b, and a trace-hook chamber i extending parallel with the bore q and formed preferably in three diameters, affording the shoulders 01' stops 0 and n.

E is the trace-hook, comprising the hookportion e on a rod f, which is retained in the chamber-2' by a spring m surrounding it and 5c confined at opposite ends between the shoul- Serial No. 430,153. (No model.)

der n and a head 9 affording a guide-bearing on the rear end of the rod, which is provided on the end-portion projecting beyond the forward end of the trace-hook chamber (wherein the most contracted portion of the chamber affords a forward bearing for the rod, as shown) with a stop or collar h. As will thus be seen, the couplings O are readily adjustable on the shafts and the cross-bar B as readily fastened in them for connecting the shafts together; and when the couplings are in place they present the trace-hooks in convenient position to have the traces attached to them. The particular construction of trace-hook shown and described is advantageous by reason of its simplicity and the protection afforded to the spring on by its inclosure.

D is a hold-back, comprising a sleeve-portion to fit around the shaft A toward its forward end, and a loop (1 extending backward from the rear end of the sleeve into proper position, with the hold-back adjusted in place,

to permit the particular strap to be passed through it. I fasten the hold-back in place by means of a set-screw d, having an inclined threaded bearing in the sleeve at such a point thereon that when the hold-back is in its properly adjusted position, wherein the loop will be under the shaft, the set-screw will extend at an angle outward from the base, to be out of the way of chafing the animal.

What I claim as new, and desire to secure by Letters Patent, is

l. A metal shaft-coupling having a bore for the shaft, a bore for the cross-piece extending at a right angle to the shaft-bore, and a trace-hook chamber between the two said bores, substantially as described.

2. A metal shaft-coupling 0 comprising an L-shaped casting having a shaft-bore q, a cross-bar bore 19 and an intermediate tracehook chamber, in combination with a tracehook E, having a spring-controlled rod-portion F con finedin said chamber, substantially as described.

3. A metal shaft-coupling 0, comprising an L-shaped casting having a shaft-bore q, a cross-bar bore 19 and an intermediate tracehook chamber "5 forming internal shoulders 0 and n, in combination with a trace-hook E having the projecting hook-portion eon a rod fin the chamber and carrying stops g and h, and a spring m confined in the chamber, sub- 5 stantially as described.

4. In combination with the coupled shafts A, hold-backs D, each comprising a sleeve having a set-screw d for fastening it to the shaft and normally extending at an angle ont- Ward therefrom, and aloop d extending backto ward from the rear end of the sleeve, substantially as and for the purpose set forth.
