NUT Loox.
No. 340,764. Patented Apr. 27, 1886.
UNITED STATES FRED CLARK, OF LULING, TEXAS.
NUT-LOCK.
SPECIFICATION forming part of Letters Application tiled February 27, 1886. Serial No. 193,469.
To a/ZZ whom, it may concern:
Be it known that I, FRED CLARK, of Luling, in the county of Caldwell and State of Texas, have invented certain new and useful Improvements in Nut-Locks; and I 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.
My invention relates to an improvement in nut-locks, the object thereof being to provide a device of this character which shall be effective in preventing nuts from becoming loose and unfastened when they are subjected to severe vibrations and jarring, such as are constantly met with on machinery of various kinds, as well as on railroad-tracks. A further object is to provide means of the above character which shall be simple and economical in construction and durable and efficient in use; and with these ends in view my invention consists in the certain features of construction and combinations of parts, as will be hereinafter fully described, and pointed out in the claims.
In the accompanying drawings, Figure l is a side View of my improvement; and Fig; 2is a section thereof', showing the clamp secured to the bolt.
A represents the fish-plates, located on each side of the rails B, in the usual manner.
C represents the ordinary screw-threaded bolt, on which is located the nut D, impinging against the fish-plate, and thereby securely holding the same in position. A
E and F represent the upper and lower arms of the clamping device, the arm E being provided with the downwardly-curved end G and with the radial groove H, formed in the bottom thereof. The said groove is provided with suitable screw-threads, whereby it is adapted to registcrwith the threads on the bolt, and thus effectually prevent the arm from slipping. The arm F is provided with a similar groove, I, formed in the upper edge thereof.
Patent No. 340,764, dated April 27,1886.
(No model.)
The arms are pivoted or hinged together, as shown at J, in such manner as to cause the grooves H and I to register with each other. The arm E is provided on its free end with the groove K, and the lower arm, F, is provided horizontallywith the hole L, through which is adapted to pass the wire M, the same continuing over the groove K, whereby it is prevented from slipping. y y,
To secure the nut against motion, the arms of the clamp are placed close against the nut and brought together, whereby the grooves H and I are caused to register with the threads on the bolt. The free ends of the arms are then secured together by means of the wire M, as shown.
I would have it understood that I do not limit myself to the exact construction shown and described, but consider myself at liberty to make such changes and alterations as properly fall within the spirit and scope of my invention. p
Having fully described my invention, whatI claim as new, and desire to secure by Letters Patent, is-
l. In a nut-lock, the combination, with a bolt and nut, of apair of pivoted arms adapted to bear against the nut, and means for securing the arms against lateral movement, substantially as set forth.
2. In a nut-lock, the combination, with a scrcwthreaded bolt and nut, of a pair of arms pivoted or hinged together, said arms having annular screw-threaded grooves formed therein adapted to register with the threads on the bolt, and means for locking the arms together, substantially as described.
In testimony whereof I have signed this specification in the presence of two subscribingwitnesses.
FRED CLARK.
