THlLL-COUPLING.

SPECIFICATION forming part of Letters Patent No. 402,527, dated April 30, 1889.

l Application filed March 5, 1889. Serial No. 301,899. (No model.)

To aZZwr/om t may concern.-

Beit known that I, GEORGE H. BUTTON, a citizen of the United States, residing at Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Thill-Couplings, of which the following is a specification.

This invention relates to a coupling for uniting shafts or pole to the front axle of a vehicle.

The accompanying drawings illustrate the invention.

Figure 1 is a side view of the parts, the axle being in section. Fig. 2 is a top view of the same parts. Fig. 3 is a section view of the thill-coupling, taken on the line 3 3. Fig. 4 is a back View of the hook presser-plate. Fig. 5

shows a modification of the presser-plate.

Figs. 6 and 7 are side and section views showing a modification of the presser-plate. Fig. 8 is a front view of the modified form of presser-plate. Fig. 9 is a view of the modified form of yoke-plate for the clip.

The letter A designates the axle of a vehicle; B, the usual clip which surrounds the axle and to which part of the coupling is attached. This clip has .the two customary ears, c, and an ordinary bolt, d, across from one ear to the other serves for the attachment of the shaftiron E. l

The special construction which constitutes my invention will now be described.

The shaft E has the usual iron, E, provided at its end with a hook, f, whose point f projects downward. This hook couples with the bolt d. To couple or uncouple the shaft E does not require the removal of the bolt. The hook f is so shaped that when the forward end of the shaft E is raised, as in Fig. l, to the usual position it has when anI animal is hitchedl to it, the point f which projects downward, will also incline forward below the bolt d. In order to couple or uncouple the shaft-hook f from the bolt, the forward end of the shaft must be lowered and allowed to rest on the ground. Thereby the hook-point f will project straight downward. It will then simply be necessary, while the forward end of the shaft is on the ground, to lower or raise the hook end of the sh aft, first forcing the presser-- plate G back from the hook.

two ears c. In Figs. l to 5 this plate is shown as taking around the exterior of the ears. The presser-plate has at its front side and top a beak or boss, h, which bears against and over the hook f. A spring, I, presses forward the plate G and keeps it hard against the hook, and thereby preventsthe latter uncoupling from the bolt d. The back of the plate Ghas a socket, i, and the front of the axle-clip B also has a socket, j, and the spiral spring I has its ends resting in these two sockets. The yoke-plate k below the axle, which unites the two ends of vthe clip -B, has one end, k, projecting forward, and is provided-on top with a grip-notch, l, which receives the lower part of the presser-plate G and coacts with the spring I in keeping the beak or boss h hard against the hook.

In the modification shown in Fig. 5 the lower part of the plate G is not designed to be gripped by the grip-notch l.

In Figs. 6, 7, and S the presser-plate is shown as seated between the two ears c and loosely attached thereto by the lateral lugs m on', two

of which take below the .said ears and two.

above. It will be seen that this construction of presser-plate operates substantially like that shown in Figs. 4 and 5. i

The yoke-plate 7c, to co-operate with the form of presser-plate shown in Fig. S, is provided at its forward-projectin g end with a slot, l', which receives the lower end, n, of the presser-plate. The presser-plate may have at its top a hooklug, o, which will afford means for engaging a suitable lever when it is desired to force the said plate back from the hook.

This 'coupling may be used with shafts or poles of vehicles.

Having described my invention, I claiml. In a thill or pole coupling, the combination of the clip having two ears, c, a bolt, d,
