PATENT OFFICE.
NUT-LOCK- SPECIFICATION forming part of Letters Patent No. 788,981, dated. May 2, 1905.
Application filed September 27, 1904. Serial No. 226,200.
To all whom, It may concern.-
Be it known that we, WILLIAM WESLEY WISE,IRA IVAN COOPER, and WILLIAM L. MIL- LER, citizens of the United States, residing at Evans City, in the county of Butler, State of Pennsylvania, have invented certain new and useful Improvementsin Nut-Locks; 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.
This invention relates to nut-locks, one object being to provide an exceedingly simple, inexpensive, durable, and efficient means to prevent loosening of the lock occasioned by jar or otherwise.
Another object of the invention resides in locking the bolt and nut against accidental loosening or separation through the instrumeutality of a peculiarly-shaped key formed of a single piece of material.
With these and other objects in view the present invention consists in the combination and arrangement of parts, as will be hereinafter more fully described, shown in the accom panying drawings, and particulary pointed out in the appended claim, it being understood that changes in the form, proportion, size, and minor details may be made within the scope of the claims without departing from the spirit or sacrificing any of the advantages of the present invention.
In the drawings forming a portion of this specification,and in which like numerals of reference indicate similar parts in the several views, Figure 1 is a perspective view of the invention. Fig. 2 is a longitudinal sectional view of the same, and Fig. 3 is a detail perspective View of the locking-key.
Referring now more particularly to the accompanying drawings, the reference character 1 designates a-bolt of ordinary form, having' its screw-threaded end 2 slotted or bifurcated longitudinally, as indicated by the character 3. The nut I has its outer face serrated at intervals, as at 5, for a purpose presently explained, and this nut is provided with the usual screw-threaded bore, whereby it may have a working fit upon the bolt, as well understood. By reason of the slotted or bifurcated end of the bolt the screw-threaded end has a tendency to spread outwardly, causing the screw-threads thereof to bite into and bind against the screw-threaded bore of the nut. This binding action in itself acts in a measure to prevent loosening of the nut; but in order to secureapositive locking engagement of the two elementsthe bolt and nuta Wedgeshaped key, having one of its sides serrated or otherwise roughened, as at 6, is driven into the slot or bifurcation 3, spreading the free end of the bolt into tight engagement with the threads of the bore of the nut, the serrations on the side of the key serving to bite into one wall of the slot or bifurcation 3 and prevent accidental displacement of the former. As clearly shown in the drawings, the key is not only of a wedge, but is also of a T, outline, the head 7 thereof being integral with its shank portion 8. In other words, it will be seen that the T-shaped key is formed of a single piece of material.
In the use of railroad-rails much inconvenience and annoyance beside the wrecking of the rolling-stock has been occasioned by the weight and jarringcaused by the latter in its movements over the rails to loosen the nuts and bolts, and therefore the present invention is particularly adapted for this specific purpose. For instance, when the bolt 1 is passed through the rail in the usual manner and the nut 2 is screwed upon the bolt until it has reached the side of the rail or the usual fish-plate, the rail and fish-plate being not shown, it is only necessary to drive the present peculiarly-formed wedge into the bifurcated end of the bolt until the integral head portion 7 of the wedge fits in corresponding serrations or the like, upon the opposite sides of the bore of the nut, the serrations or teeth 6 of the key engaging one of the walls of the bifurcation and preventing accidental displacement of the key. It is obvious, therefore, that when the key is positioned as explained the nut cannot turn upon the bolt or the bolt with respect to the nut.
What is claimed is A nut-lock, comprising a bolt having one of its ends screw-threaded and bifurcated, a screw-threaded nut having a Working fit upon the screw-threaded end of the bolt, said nut having one of its faces roughened, and a T- shaped wedge fitting in said bifurcation with the head portion thereof registering with the roughened surface of the nut, the Wedge hav' ing one sideof its shank portion provided With teeth for engagement With one Wall of the said bifurcation to prevent accidental Withdrawal of the key therefrom, the head and shank portion of the key being formed of a single piece of material. 7
In testimony whereof We affix our signatures in presence of two Witnesses.
