l NiTnD STATES PATENT STEPHEN BURDSALL, OF FREMONT, OHIO, ASSIGNOB TO THE HERBRAND COMPANY AND THE FBEMONT DROP FORGE COMPANY, BOTH OF SAME PLAGE.

THILL=CUPLING.

SPECIFICATION forming part of Letters Patent No. 369,689, dated September 13, 1887.

Application filed December 27, 1886. Serial No. 222,729. (No model.)

To all whom it 71mg/ concern:

Be it known that I, STEPHEN BURDsALL, of Fremont, in the county of Sandusky and State of Ohio, have invented certain new and useful Improvements in Thill-Oouplings, of which the following is a specification.

This invention relates to thill-couplers, and has for its object to provide against the rattling of loose parts; and it consists in the peculiar construction and combination of the several parts comprising my device, as hereinafter fully described, and pointed out in the claim.

I-n the accompanying drawings, Figure 1 is a perspective view of my new thillcoupler. Fig. 2 is a detached view of the clip baseplate having the eye-arms forming a part thereof. Fig. 3 is a detached view of the coupling-bolt, showing a slot by which it is secured in place in the said eye-arms. Fig. 4 is a detached view of a metal spring-plate. Fig. 5 is a detached view of a hooked latching device located inrear of the couplingbolt and designed to lock the coupling-bolt and bearing against the spring. Fig. 6 shows a clip with arms attached forming part thereof.

A is a base-plate secured to the axle by a clip, B, and has two arms, O O, formed with it, having eyes o c. The rear ends of said arms form shoulders which bear against the side of the axle, and the rear end of the plate also has a shoulder bearing against the rear side ofthe axle, and tlie plate has two holes for securing it to the axle by means of a clip, B.

D is a thilliron of the common construction, and E is a coupling-bolt having a crosscut slot or groove near its point, instead of being screw-threaded, for a purpose hereinafter shown.

G is a pin or bolt having leaf H on its middle part, and also having on one end a latchhook, K, which engages with the slot or groove in the coupling-bolt E. In the rear part of the arms O O are made holes I I, for the reception of the pin G, one of said holes having a slot, t', in connection with it to let the leaf H pass through in inserting the said pin.

L is a metal leafspring, foldednto be placed between thethilliron and the pin or bolt G, as seen in Fig. 1. The forward end is bent into half-circle to lit around the end of the thill-iron. A block of india-rubber may be substituted for the metal spring with the same effect.

In Fig. 6 the arms O O are formed on the clip. The'effect is with .regard to firmness.

From the foregoing it will be seen that the spring, bearing against both the thill-iron and leaf on the pin, will effectually prevent any rattling of the parts, and also that the position of the leaf on the pin is such that it, by the tension of the spring, holds the latch down firmly upon the coupling-pin, thereby locking the parts together. By this construction, also, it will be seen that the coupling or the uncoupling of the thills is very quickly and readily done.

Having described my invention, what I claim, and desire to secure by Letters Patent,

The combination, with a clip-iron having the eye-arms and a thill-iron, of a couplingbolt having a cross slot or groove near its point, a pin or bolt in rear ot' the coupling bolt and having a leaf, and a hook-arm on outside of eye-arm' and engaging with said coupling-bolt, and a spring-bearing between the thill-iron and the said leaf on rear bolt, all constructed to operate substantiallyinthe manner and for the purpose specied.

STEPHEN BURDSALL.
