THlLL-COUPLING.

SPECIFICATION forming part of Letters Patent No. 439,979, dated November 4, 1890.

Application filed August 20, 1890. Serial No. 362,560. (No model.)

To all whom it may concern:

Be it known that I, JULIUS H. SENDEN, of Lexington, in the county of Lafayette and State of Missouri, have invented a new and useful Improvement in Thill-Oouplings, of which the following is a specification.

The object of the invention is to provide a safe, simple, durable, and cheap thill-couplin g provided with an efiective anti-rattler. The invention consists in the construction and arrangement of parts hereinafter described and claimed.

Figure l is a longitudinal section of my improved thill-coupling, showing the thill in its operative position. Fig. 2 is a similar view showing the thill in its downward position, and Figs. 3 and 4 are detail views of the thillcoupling and rubber washer.

A represents the clip of the usual construction, except that in its front wall between the two forward-projecting lugs or ears A is formed a rectangular or other shaped opening A countersunk or beveled from the inside outward, and in each of said lugs or ears is formed a longitudinally-extending slot A rounded at the ends.

B is the coupling-pin flattened on its upper and lower sides, rounded on its front and rear edges, and secured firmly in any suitable manner at its ends in said slots A.

O is the anti-rattler block, of rubber or other suitable material, projecting at its front face through the opening A into the space between the lugs A, and having a marginal flange C beveled to correspond with the countersink or bevel of the opening A D is the thill-iron having an elongated head D or a head the thickness of which between its axis and rear end is greater than that between its lower face and axis, so that when in the position shown in Fig. 1 the said rear end will bear against the block 0 to prevent rattling, and when the thills are swung down the said lower face of the head will be swung clear of the inner face of the block 0 and allow the block to expand. Ordinarily this block is held at all times compressed by the head of the thill-iron, so that it soon loses its elasticity and becomes useless as an anti-rattler;

but not so with my construction, which will permit the block to retain its elasticity for quite a long time.

The head D has a transverse eye D receiving the flattened pin B, and a slot D leads downward from the upper side of the head into said eye, the slot being of less width than the pin, so that when the thill-iron is in the position shown in full lines, Figs. 1 and 2, it cannot become uncoupled; but when the thill iron is swung upward and rearward to the po sition shown in dotted lines, Fig. 1, the slot D will be in horizontal alignment with the pin B, and then by moving the thill-iron forward it may be disconnected. By a reverse movement the parts may be connected.

Having thus described my invention, what I claim as new is- 1. In a thill-coupling, an axle and thill-connecting clip having the forward-projecting lugs, and an anti-rattler-receiving opening through its front wall between said lugs and countersunk or beveled from the inner face of said wall, substantially as set forth.

2. In a thill-coupling, an axle and thill-connecting clip having the forward-projecting lugs connected by a flattened pin, and an anti-rattler-receiving opening through the front wall of the clip between the lugs and countersunk or beveled from the inner face of the said wall, substantially as set forth.

3. A thill-coupling and anti-rattler consisting in the clip having an opening through its front wall, beveled or countersunk from the inner face of said wall, parallel lugs projecting from the clip at opposite sides of said opening and provided with a flattened connecting-pin and the elastic block projecting through said opening and having a flanged base engaging the said countersink or bevel, and the thill-iron having an oval or elongated head turning on said pin engaging the said block when the shafts are horizontal and disengaged therefrom when the shafts are swung up or down, substantially as set forth.

4. The herein-described thill-coupler, consisting in the clip A, having forward-projecting lugs A, a countersunk opening A between'said lugs, and the longitudinal slots A in said lugs, the flanged block 0, projecting the width of the pin, substantially as set through the opening A the pin B, secured forth.

at its ends in said slots and flattened on its upper and lower faces, and the thill-iron D, having an elongated or eccentrically-formed head D provided with eye D and slot D communicatingtherewith, of less width than I JULIUS H. SENDEN.
