IMPROVEMENT IN THlLL-COUPLINGS.

Specification forming part of Letters Patent No. 154,648 dated September 1, 1874; application filed July 11, 1874.

To all whom it may concern:

Be it known that I, OLIVER C. CORNELL, of Sing- Sing, in the county of Westchester and State of New York, have invented a new and valuable Improvement in Anti-Rattler for Shaft-Couplings and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being bad to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.

Figure 1 of the drawing is a representation of a plan view of my anti-rattler for shaftcouplings. Fig. 2 is a sectional view of the same. Fig. 3 is a detail view of the same.

This invention has relation to means for preventing thill-couplin gs from working loose and rattling; and it consists in the employment of an india-rubber block, partly inclosed by a metal spring, which spring is so shaped that it will hug the eye of the thill-iron and I hold the rubber block in its place, at the same time preventing the rubber from undue wear, as will be'more fully explained hereinafter.

In the annexed drawings, A designates an axle B, the embracing portion of a clip, and B the clip-bar or yoke. G is the thill-iron; g,

its eye, and c the bolt which connects the thill to the ears a a of the clip. These parts are all constructed in the usual we1l-known manner. S designates an india-rubber block, presenting a front concave surface and a back flat surface. This block S is inclosed by a metal spring-shield, D, which is shaped somewhat like the capital letter A. One limb, d, of the spring is flat, and rests upon the front end of the yoke B, and bears against the front side of the clip. The other limb, d, is curved, and of such length as to extend well beneath the eye 9 of the thill-iron (J, as shown in Fig. 2.

The spring D serves two purposes: it affords a durable and smoothmetallic surface, against which the eye of the thill-iron plays freely, and it also securely holds the rubber block S in place by reason of the front limb, d, hooking under the eye 9. The two springs combined, when compressed between the eye 9 and the clip, prevent rattling, and also prevent the casual detachment of thebolt c.

I am aware that a rubber block partly inclosed by a guard and secured by means of a bolt to a detached clip-bar, as .shown in Letters Patent No. 64,219, dated April 30, 1867, is not new. t

What I claim as new, and desire to secure by Letters Patent, isn The combination of the'eye g, the thill-iron G, the yoke B, the clip B, the metallic springshield D, inclosing the india-rubber cushion S, having one end, d, resting upon the front end of the yoke B, and bearing against the front side of the clip B, and the other end, d, curved and extending beneath the eye 9 of the .thill-iron G, as shown and described.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.

OLIVER o. CORNELL.
