UNITED STATES PATENT OFFICE.
GEORGE WILLIAM VANDEVENDER, OF MINGO, VVES'PVIRGINIA.
NUT-LCQK.
SPECIFICATION forming part of Letters Patent No. 705,797, dated July 29, 1902. Application filed May 10, 1902. Serial No. 106,813. (No model.)
To all? who/wit may concern:
Be it known that I, GEORGE WILLIAM VAN- DEVENDER, a citizen of the United States, residing at Mingo, in the county of Randolph and State of West Virginia, have invented a new and useful Nut-Lock, of which the following is a specification.
The invention relates to improvements in nut-locks.
Theobject of the present invention is to improve the'constrnction of nut-locks and to provide a simple and comparativelyinexpensive one designed for use on rail-joints, bridge constructiomand various parts of machinery subject to vibration and capable of eifectually preventing a nut from being jarred loose or accidentally unscrewed.
A further object of the invention is to pro vide a device of this character which will not become displaced from the fish-plate or other part on which it is mounted when it is temporarily disengaged from a nut to permit an adjustment of the latter.
The invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended.
In the drawings, Figure 1 is aside elevation of a rail-joint provided with a nu t-lock constructed in accordance with this invention. Fig. 2 is a vertical sectional view of the same. Fig. 3 is a horizontal sectional View. Fig. 4 is a detail view of the locking device. Fig. 5 is a detail view of the nut,illustrating the construction of the inner face thereof. i
Like numerals of reference designate corresponding parts in all the figures of the drawings. i
1 designates a fish-plate designed to be arranged at a rail-joint in the usual manner and provided with bolt-openings 2 and having longitudinal grooves 3 for the reception of locking devices 4 for engaging nuts 5 of bolts 6. The bolts pass through the webs of the rails and through the opposite fish-plate in the usual manner and the nuts are provided at their inner faces with a series of recesses 7, adapted to be engaged by the looking devices. The groove 3 is composed of an innernarrow portion 8 and a wide outer portion 9, which communicates with the boltopening 2, and these wide and narrow portions are provided with undercut edges f0rming dovetailed grooves. The wide portion 9 of the groove is located adjacentto the boltopening and forms a pair of shoulders 10, which are adapted to be engaged by corresponding shoulders 110E the sides 12 of the locking device, whereby the latter is firmly heldin engagement with the nut. The locking device, which isconstructed of steel or other resilient material, is composed of the said sides 12 and a connecting end portion 13, which engages the Hut. The sides are provided withtront and rear V-shaped side recesses 14 and 15 to provide dovetailed portions to interlock with the dovetailed grooves, and these recesses 14 and 15 form opposite inclined faces. The recesses 15 are deeper than the recesses 14 and the dovetailed portions are of difierent sizes to form the said shoulders 11 for engaging the shoulders of the fish-plate, whereby the locking device is held in engagement with the nut. The sides 12 are reduced adjacent to the end portion 13 to increase their resiliency and the end portion is centrally enlarged, as clearly shown in Figs. 1 and 4. The" resiliency of the sides holds the locking'device in engagement with the nut, as clearly shown in Fig. 1. When it is desired to unscrew the nut, the sides 12, which are enlarged at their rear ends to form grips 16, are compressed and are drawn inward into the reduced portion of the groove away from the nut, which is then free to be rotated, and there is no liability of the look ing device becoming accidentally detached and lost while the nut is being removed or adjusted.
Itwill be seen that the nut-lock is exceedingly simple and inexpensive in construction, that it is adapted to firmly hold a nut against accidental 1'ot-ation,and' that it is capable of enabling the same to be readily removed when desired. It will also be seen that the locking device cannot become accidentally detached from the plate onwhich it is mounted when it is moved backward awayfrom the nut, and that although shown applied to a rail-joint it is capable of being advantageously employed in various other places where the parts are subject to jar and vibration.
What I claim is 1. A device of the class described comprising a plate having a bolt-opening and provided with a dovetailed groove extending from the bolt-opening and having an inner narrow portion and an outer wide portion forming shoulders, and a nut-engaging looking device arranged in the groove and having dovetailed portions of different sizes forming shoulders for engaging the shoulders of the plate, whereby the locking device is held in engagement with a nut, substantially as described.
2. A device of the class described comprising a plate having a bolt-opening and provided with a dovetailed groove extending from the bolt-opening, and a resilient locking device composed of two sides provided with longitudinal dovetailed portions arranged in the said groove, the sides of the locking device being provided with means for engaging the plate, whereby the locking device is held in engagement with a nut, substantially as described.
3. A device of the class described comprising a plate having a bolt-opening and provided with a dovetailed groove extending from the bolt-opening, and a locking device having dovetailed side portions interlocked with the Walls of the groove and provided with projecting portions adapted to be compressed to permit the locking device to slide in the groove, said locking device being provided with a connecting end portion enlarged between the sides and the latter being reduced at the end portion to increase their resiliency, substantially as described.
4. A device of the class described comprising a nut having recesses and adapted to engage a bolt, a plate having a bolt-opening and provided with a dovetailedgroove extending from the bolt-opening and provided between its ends with shoulders, and a locking device having resilient sides provided with dovetailed portions interlocked with the walls of the groove, and provided with means for detachably engaging the said shoulders, whereby the locking device is held in engagement with the nut, substantially as described.
In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.
GEORGE WILLIAM VANDEVENDER.
