ratesi aisasjaia;
Application filed September 14,1912. Serial No. 720,408.
To all whom it may concern Be it known that I, Hunnn'r C. HART, a citizen of the United States, residing at Unionville, in the county of Hartford and State of Connecticut, 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, reference being had to the accompanyin drawings, and to letters or figures of re erence marked thereon, which form a part of this specification.
This Invention relates to improvements in.
nut locks.
The object of the invention Is to provlde a simple and economical device for securely fastening a nut to a bolt.
The invention therefore comprehends improvements in the details of construction and arrangement of parts which will be hereinafter described and particularly pointed out in the claims.
In the drawings: Figure 1 is a perspective view of my im roved nut lock. Fig. 2 is a horizontal section of the same. Fig. 3 is a detail perspective view of the locking device and .a portion of the bolt. Fig. 4 is a detail of the blank. Fig. 5 is a perspective view of a slightly different form of the invention.
1 indicates a threaded bolt formed with an annular oove 2, adjacent the threads. The ends 0 the bolt beyond the annular groove is reduced in diameter so as to permit of the ready application of a nut 3.
The locking device comprises a base p01,- tion 4, formed with a slot 5 and a front portion 6, having its free end bent at right angle to provide an abutment 7. The locking device 1s stamped in blank form from sheet metal, a detail of the blank being shown in Fi 4.
In Fig. 5 I have shown a slightly diflt'erent form of the invention, the fastenlng device being the same as that previously described, except that the front end portion is disposed adjacent the center of the bolt rather than above the level of the top of the bolt. The bolt in this form of the invention is formed with a slot 10, to receive the abutment 7, but in other respects, the details are the same.
When applying the form of the invention shown in Figs. 1 to 5, the base portion of the locking device is fitted in the annular groove 2 of the bolt, and then the front portion 6, is bent inwardly toward the nut until the abutment 7, overlies the bolt and bears against the base portion. When so ositioned the abutment 7, prevents the loc ing device becoming disengaged from the bolt, hence the nut is effectively locked in position. If in screwing the nut on the bolt, the face of the nut should be back of the rear face of the base portion 4, the prongs of the latter can be stuck with a tool to cause them to enga e with the nut, hence insuring of the nut being tight. This may be accomplished by forcing the abutment against the base portion.
By the construction described, the locking device can be turned on the bolt to any convenient position and so permit of its ready and quick application. Furthermore, by reducing the end of the bolt, the nut can be more readily applied to the threaded portion.
In the second form of the invention, after the nut has been applied 'to the bolt, the abutment 7, is driven or forced into engagement with the slot 10, consequently the locking device is securely held in position, and the nut is prevented from turning.
What I claim is 1. In combination, a bolt formed at its free end with a reduced portion and a groove adjacent thereto, and a nut locking device having a base portion and a front portion, the free end of the latter being bent to form an abutment to engage the bolt to hold said locking device in position, the base portion having a slot which, engages with the neck of the bolt formed by the groove.
2. In combination, a bolt formed at its free end with a reduced ortion and an annular groove adjacent t ereto, and a nut locking device formed from a single piece of metal bent to provide a base, a front portion and an abutment, the base portion having a slot in which fits the neck of the bolt formed by-the groove, the front portion extending over the front end of the bolt and the abutment engaging with said bolt to lock the locking device in position and hold a nut on said bolt.
3. In combination, a bolt formed at its free end with a reduced portion and a groove adjacent thereto, a nut on the bolt, and a nut locking device formed from a single In testimony whereof I have signed my piece of sheet metal and having a slot WhlOh name to this specification in the presence of engages with the neck of the bolt formed by two subscribing witnesses.
