UNITED STATES PATENT OFFICE.
NORRIS M. COMPTON AND VILLIAM II. LONGCOY, 'OF SULLIVANVILLE, NEW YORK.
THlLL-COUPLING.
SPECIFICATION forming part of Letters Patent No. 444,333, dated January 6, 1891.
Application led June 2l, 1890. Serial No. 356,261. (No model.)
To all whom it may concern:
Be it known that we, NORRIS M. COMPTON and WILLIAM H. LoNGcoY, citizens of the United States of America, residing at Sullivanville, in the county of Chemung and State of New York, have invented certain new and usefulImprovements in rPhill-Couplings; and We do hereby declare the following to be a full, clear, and exact description of the invention, such as Will enable. others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.
This invention relates to improvements in thill-couplings, the object thereof being to provide means for preventing the rotation of a bolt used in connection with a spring see tion or member of the thill.
Our invention consists in the combination of a spring member of a chill-coupling, having a perforation through which the bolt passes, of a rigid portion adjacent thereto, one of the parts being provided with depressions or projections, While the head of the bolt has corresponding projections or depressions, the parts being adapted to be held together by said bolt, as will be hereinafter fully set forth.
In the accompanying` drawings, forming part of this specification, Figure l is a sectional view showing the improved bolt-fastener applied to our thill-coupling. Fig. 2 is a plan view showing the bolt removed, and Fig. 3 is a perspective view of the bolt.
A refers to the rigid member, and B to the spring member, of 'the Jthillcoupling In the present instance I have shown the spring member provided adjacent 'to the bolt-opening b with depressions c c, which are located at right angles with each other, so as to provide at angles of forty-five degrees therewith raised portions between the depressions. The head of the bolt, on its under side, is provided with four corresponding projections, Which are adapted to lie within said recesses, While the depressed portions at the corner of the head of the bolt lie immediately over the raised portions of the spring member. By this construction it will be seen that the bolt maybe turned and the resiliency of the spring member will hold the parts in connection to prevent rotation of the bolt and provide a secure lock. The head of the bolt Inay be of ordinary construction-that is, rectangular or square-and may have a transverse slot, so that it can be turned by an ordinary screwdriver. It Will be obvious that the depressions Inay be changed from the spring member to the bolt and vice versa, or that the spring member may be threaded and the head of the bolt lie in recesses in the rigid bar A, such change or modification being within the scope of our invention.
By the use of such adevice auxiliary locking means for tlIill-couplings made up of dierent pieces are entirely avoided, and a simple and effective lock for the bolt provided.
We claim- In a thill-conpling comprising the rigid and spring members movably engaged at their inner ends, recessed, as described, to conjointly form the bolt-bearing, said members extending parallel, the rigid member having a threaded perforation and the spring member having on its under side adjacent to the front end an opening registering Wit-h said threaded opening, said spring member having on its outer face adjacent toits opening recesses or depressions, in combination with a headed bolt provided with projecting portions adapted to lie within said recesses to hold the bolt against rotation and lock the free forward end of the spring member, substantially as set forth.
In testimony whereof we affix our signatures in presence of two Witnesses.
