Patented June'l, 1909.

Application filed March 20, 1909. ,Zserial No. 484,821.

To all whom it may concern:

Be it known that I, MILO L. DECKER, a citizen of the United States, residing at Maxwell, in the county of Lincoln and State of Nebraska, have invented certain new and useful Improvements in Hut-Locks; and I do hereby declare the following to be a full, clear, and exact descri tion 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 I of this specification. 15

This invention relates to new and useful improvements in nut locks and com rises various details of construction, com inations and arrangements of parts which will be hereinafter fully described and then specifically defined in the appended claim.

My invention is illustrated in the accom panying drawings, in which Figure ,1 is a perspective view of the in- 7 vention showing a lock applied to a nut upon showing the lock applied a series of grooves grooves in the bolt.

a bolt. Fig. 2 is a detail of one end of the bolt. Fig. 3 is an'enlarged perspective view to the nut, and Fig. 4 is a sectional view. Fig. 5 is an end view of the nut and pawl mounted thereon.

Reference now being had to the details of the drawings by letter, A designates a headed bolt having a threaded portion with B formed longitudinally. therein, and D designates a nut mounted upon the threaded portion of nut having a threaded bore as usual and a F designates a pawl having a laterally rojecting lug E which is adapted to swing into said recess and a portion of said lug pro jects within the bore of the nut and is adapted to engage one or another of: the Said pawl is pivotally connected to one end. of the spring G which in turn is fastened to one end of the nut and the bolt, said said spring is adapted to hold the pawl frictionally and serves to retain locked relation after the latter is swung into a groove.

In applying the nut, it is fitted upon the threaded portion of tire bolt in the usual manner and, when it is desired to lock the nut, the pawl is swung upon its pivot so that the laterally projecting portion of the lug thereon will engage a groove in the bolt. The spring beers with sufficient frictional force against the pawl to hold the same in its locked relation. A knob or headed in K projects from the free end of the paw and aii'ords means for throwing the same in one direction or the other as ma be desired;

From the foregoing, it wil be noted that by the provision of a nut look as shown and.

described a simple and efficient means is aiiorded 'whereby'a nut may be securely held from loosening when adjusted upon a bolt and so arranged that the nut maybe easily and uickly removed when desired.

What 1c aim to be new is 1- A nut lock comprising a bolt having a threaded portion with grooves formed longitudinally therein and transversely across said threaded portion, a threaded nut fitted to said belt, a spring fastened at one end to the end of said nut, a curved pawl pivotally the pawl in a connected to said spring and adapted to be held by the latter Emotionally against the end of the nut, a lug projecting from the inner concaved edge of said pawl and extending laterally and adapted to engage one or another of the grooves in the bolt, and a knob upon the free swinging end of said pawl, as shown and described.

In testunony whereof, I hereunto aflix my signature 1n the presence of two witnesses.

MILO L. DECKER.
