THlLL-COUPLING.

' the bail when thelatter is held in place by the To all whom it may concern.-

Be it known that 1, WILLIAM P. TRACY, of Grand Rapids, in the county of Kent and State of Michigan, have invented a new and useful Improvement in Shaft Couplings and Supporters; and I do hereby declare that the following is a full, clear, and exact description of the same.

My invention is an improved carriageshackle, having for its object security against rattling, and to hold the shaft automatically in a vertical position when the carriage is not in use.

In the accompanying drawings, Figure 1 is a perspective view of my improved shackle. Fig. 2 is a vertical section through the same. Fig. 3 is a perspective view of one of the parts detached.

In these drawings, the bail 0, formed with an eye for the pintle d, connects the shaft to the shackle. The shackle is attached to the axle in the usual manner, and is provided with ears 0 c of ordinary construction. The body of the shackle, however, is of special construction, as shown in the figures. It is formed with a plate, f, with a plane surface adapted to lie against the under side of the axle, and has preferably a small vertical flange, 9, which bears against the front edge of the axle. Underneath the plate the enlarged part h of the shackleis chambered to receive acoiled spring, It. The rear end of the shackle is plugged with an adj listing-screw, Z, by means of which the tension of the spring may be regulated. Ablock, m, provided with a stud, 1, is adapted to fit between the ears, the stud projecting into the interior of the spring. The block has also upper and lower flanges, 9 9 so that it is securely held in place between the ears, and may slide freely backward and forward. It bears upon the spring, which has play enough to keep the block pressed forward against the eye of (No model.)

pintle. When the spring loses-its elasticity, it may be set up by simply turning the nut in the rear without the trouble of taking out and replacing the worn spring, as is the casein the spring-shackles in ordinary use. The front part of the block is formed to fit the rear end of the bail, and has also a transverse groove, 4, adapted to receive a transverse rib on the bail. This rib is so arranged that when the shaft is raised the rib presses back the block until it reaches the groove 4, in which it lodges and holds the shaft in a vertical position. The construction is the same for both shafts, and these ribs serve to retain the shafts in an upright position when the carriage is not in use.

I do not limit myself to the particular construction or form of the shackle or block.

I claim as my invention- 1. A shackle adapted to fit the axle and chambered to receive a spring, a spring inserted therein, and a block fitted between the ears of the shackle and interposed between the spring and the bail, all substantially as described.

2. A shaft-coupling and supporter consist- W. H. SHELLER, WILLIAM OswALD.
