NU T LOCK. APPLICATION FILED AUG. l5| I919.

WIZWESSES GEORGE L. MOORE, OF DEXTER, IOWA.
NUT-LOCK.
Specification of Letters Patent. Patented Sept, 21, 1920.
Application filed. August 15, 1919. Serial No. 317,800.
To all whom it may concern:
Be it known that I, GEORGE L. MOORE, a citizen of the United States, residing at Dexter, in the county of Dallas and State of Iowa, have invented certain new and useful Improvements in Nut-Locks, of which the following is a specification.
My invention relates to new and useful improvements in a nut lock.
The principal object of the invention is the provision of a device of this character which is simple and inexpensive in construction but which will securely hold the nut upon, the bolt.
A further object resides in the provision of a key adapted to be connected to the nut and means for securing the key in position.
With these and other objects in view my invention consists in the novel details of construction and arrangement of parts which will be more clearly understood from the following specification and drawings in which:
Figure 1 is a side elevation, partly in section, showing the nut in position upon the bolts.
Fi 2 isa face view of the nut with the key 1n position.
Fig. 31s a detailed perspective of the key. F Fig. 4 is a section on the line 4-4 of Fig. 5 is a face view of a slightly modified form of the invention, and
Fig. 6 is a side elevation of the key used in the modifiedform shown in Fig. 5.
In the drawings the numeral 1 indicates the object through which the threaded bolt 2 is adapted to pass. The nut is indicated at 3 and as shown in Fig. 2 of the drawing the nut is preferably square although it will be understood that other shapes may be used as will be later described. An elongated groove 4 is formed in one face of the nut 3, adjacent-oneedge, and a key is adapted to be received in the groove. The key is indicated at 5 and is formed with a straight portion 6 adapted to engage the bottom of the groove 4. This straight end 6 of the key is adapted to be welded to the nut whereby the key will be secured permanently to the nut. The key is curved to form the inclined portion 7 which terminates in a straight end 8 and is provided with a projection 9 transversely thereof. This rejection 9 is brought to an edge where y when the nut is screwed upon. the
bolt this sharpened edge of the projection w1ll engage the object 1 through whichthe bolt passes. The key 5 has a thickness equal to the depth of the groove 4 so that the projection 9 will project from the face of the nut when the key is wholly seated in the groove.
When in use the parts will be assembled as indicated more particularly in Fig. 1 of the drawing. The threaded bolt 2 is passed thereon. The key 5 will be in the position illustrated and as the nut is screwed upon the bolt the sharpened edge of the projection 9 will engage the object 1 and if said object is of relatively soft material will be embedded therein. Of course if the object is of hard metal the point would not embed itself but would frictionally engage the obj ect to such an extent that the nut could not unscrew. As the nut is screwed upon the bolt the inclined portion 7 of the key 5 willbe forced back into the groove 4.
As stated above Figs. 5 and '6 show a slightly modified form of the invention wherein an eight sided nut is used and the key is of curved formation. The eight sided nut is indicated at 10 and is provided with an arcuate shaped groove to receive the key through the object 1 and a nut 3 is screwed 11. The key is provided with the straight invention. The key is provided with the inclined portion 13 and a sharpened projection 14 is formed at the end of the inclined portion. The operationof this modified form of the invention ,is the same as that in the preferred form. When the nut is screwed upon the boltthe pointed or sharpened projection 14 will engage the object through which the bolt passes so that'the nut will be held against reverse movement to unscrew.
In carrying out my invention a nut may be used of different thicknesses and of course the key will be of such a size as to be of greatest advantage on the work used. The groove in the nut will be of sufliclent depth to receive the size of key used.
The foregoing description and the drawings have reference to 'whatmay be considered the preferred, or approved form of my invention. It is to be understood that I may make such changes in construction and arrangement, and combination of parts, materials, dimensions, etc., as may prove expedient and fall Within the scope of the appended claim.
Having fully described my invention What I claim as new and desire to secure by Letters Patent is A nut having a groove formed in one face thereof, and a flexible key having a thickness equal to the depth of said groove and having one end resting solidly upon the bottom of said groove and the opposite end extending normally beyond the face of the nut and provided With a projection at its end Which Would project beyond the face 15 of the nut when the key is Wholly Within the groove.
In testimony whereof I afiix my signature in presence of two Witnesses.
