DRAFT Sl-IACKLE FOR VEHICLES.

@PECIPICATION forming part Of Letters Patent No. 378,539, dated February 28, 1888.

Application filed July 17, 1886. Serial No. 208,322. (No model.) i

To all whom, it may concern:

Be it known that we, J AMES E. Borsronn, a citizen of the United States of America, residing in the city of Auburn, Cayuga county, and State of New York, and, THoMils L. CHURCH, also a citizen of the United States, residing in the city of Syracuse, county of Onondaga, and State of New York, have i11- vented a new and useful Improvement in a Draft-Shackle, of which the following is a specification.

The object of the invention is to have a draftshackle for vehicles that will always be tight and close around the bolt connecting it with the clip on the axletree, preventing any noise or rattling, and also to have a shackle by which shafts or poles can be removed or attached quickly. \Vc attain these objects by the mechanism illustrated in the accompanying drawings, in which Figure 1 is a side elevation of the shackle closed, and Fig. 2 represents the same open.

In the drawings, the letters A A represent the eye of the shackle. Fig. 1 represents the shackle with the eye A A closed around the bolt E of clip attached to the axle-tree of 2 represents the shackle with the eye open and spring thrown up so as to remove the thills.

B B represent the two parts of the shackle, the one part hinged to the other at point H.

0 represents an adjustable yoke around the two parts of the shackle.

D-represents the spring which presses the yoke 0 onto the shackle B B and keeps it closed tightly around the bolt E.

E represents the bolt to which the clip is attached.

F represents a tight collar around the bolt and rests against the pin G. The collar F and the pin G prevent the spring D from sliding along the shackle-bar J.

H represents the hinge of the shackle, and by means of which the shackle may be opened and shut when the spring D is pushed down to the collar F.

The two parts B B are made on an incline, so that when the shackle is attached to the carriage the adjustable yoke O is pressed along the incline by spring D, closing the eye A A and holding it firmly around the bolt E, thus making any rattling of these parts an impossibility. The slight opening in eye A A, as shown in Fig. l, is to provide for any wear of bolt E, permitting the eye to close as the bolt may wear, the pressure from the adjustable yoke O and spring D keeping the eye A A firmly in place around bolt E.

To attach or detach thills or pole with this shackle only requires a slight pressure from the thumb and fingers, pressing back yoke O and spring D to the collar F, and thus permitting the eye A A of shackle to open, as in Fig. 2.

In the drawings the letters represent the various parts of a draftshaekle as follows: A A, the eye; E, the bolt of clip on axle-tree of carriage, said bolt resting in the eye of shackle when thills or pole are attached to carriage; B B, the two parts orjaws ofthe shackle, the one part hinged to the other; (i, the adjustable yoke; D, the spring; H, the hinge, hinged with or without a rivet; F, the collar; G, the pin; J, the bar of the shackle.

WVe claim as our new invention Adraft-shackle comprising two hinged jaws, B B, a divided eye, A A, a yoke, O, and spring D, all combined and operating as above described, together forming an improved selfadjusting draft-shackle for vehicles.
