THlLL-COUPLING.
SPECIFICATION forming part of Letters Patent N o. 758,193, dated April 26, 1904.
Application filed April '7, 1902. Renewed March 8, 1904. Serial No. 197,177. (No model.)
monte., in the county of Los Angeles and State of California, have invented new and useful Improvements in Thill-Couplings, of which My invention has for its objects the ready coupling and uncoupling of the shafts or tongue from the axle and the prevention of noise of the thill in the coupling when in use.
My invention is described herein and is illustrated in the accompanying drawings, form? ing a part thereof, in which- Figure 1 is a perspective view of the fragment of a thill and an axle with my coupling applied to couple them together. Figs. 2 and 3 are side views of the same with the axle removedfcut on the vertical plane on lines 2 and 3, respectively, of Fig. 1 looking in the direction indicated by the arrow.
In the drawings, A is the axle, to which the thill-coupling is mounted in the usual manner. The thill-coupling is composed of the clipB, which surrounds the axle, which clip hasthe forwardly and downwardly projecting arms B', having an upwardly-opening notch B", the lower portion of which projects toward ,the
front of the arm for the reception therein ofv the ends of the bolt, which passes through the thill-iron D and remains therein when the thill is removed from the coupling-iron. This bolt is a smooth piece of iron without a head, so that it may be easily removed from the thilliron in case it is desired to use the thill in a buggy not provided with my improved thillcoupling. In the lower part of the arm B' is rotatively mounted a rod E, the ends of which project beyond the arms, on which ends are rigidly mounted stop-plates F to prevent the longitudinal movement of bolt C when the thill is coupled to the axle` which arefattached to catches H, also rigidly affixed to rod E, which catches prevent bolt O from becoming accidentally displaced from the notches. The stop-plate and catch may be cast integral, if desired. The backward movement of these stop-plates is prevented by lugs B", which keep the catches from contacting with bolt C.
On rod E between the arms B is rigidly attached a spring Gr, the free end of which bears firmly against the ends of the thill-iron and keeps it and bolt C from having any vibratory movement, thereby avoiding the rattling noise incident to the use of the thill when coupled in an ordinary coupling without any antirattling device. In removing the thill from the coupling it is unnecessary to use a wrench to remove the thill, as by pressing the spring toward the clip and the catch away therefrom the thill may be raised to carry the bolt C out of the notch. If the bolt C is firmly xed in the thill-iron, the stop-plates may be omitted.
Having described my invention, what I claim as new, and desirel to secure by Letters Patent, is-
l. A thill-coupling composed of aclip havin g forwardly and downwardly projecting arms, said arms having in the upper portion thereof an upwardly-opening recess therein adapted for the entry and retention of a bolt; a rod extending through the lower portion of the said arms; a spring rigidly aflixed to said rod and extending upwardly and adapted to bear against the end of the thill-iron when in said coupling; catches on the ends of said rod exterior the said arms extending upwardly and adapted to prevent any longitudinal movement of a bolt in the recesses in said arms.
2. A. thill-coupling composed of a clip having forwardly and downwardly projecting arms, said arms having a notch in the top thereof; a rod mounted in the downwardly-projecting portion of said arms; a stop-plate and catch aflixed to said rod exterior the said arms; a spring affixed to lsaid rod between said arms and adapted to bear against the thill iron when in place in the couplingin combination with a thill having a bolt in the iron thereof adapted to slip into the notches of the arms of the clip.
In witness that I claim the foregoing I have hereunto subscribed my name this 1st day of April, 1902.
