H. LIVINGSTON.
NUT-LOOK.
No.175,12Z. Patented March 21,1876.
Q I w Z k-WWW UNITED- STATES PATENT OFFICE.
HERBERT LIVINGSTON, OF HANNIBAL, MISSOURI.
IMPROVEMENT IN NUT-LOCKS.
Specification forming part of Letters Patent No. 175,122, dated March 21, 1876; application filed August 24, 1875.
To all whom it may concern: I I Be it known that I, HERBERT LIVINGSTON,
of Hannibal, county of Marion, State of Misfollows, due reference must be. had to the ac-- (-ompanying drawing, forming a part of this specification, and in which .Figure 1 is a side view of a bolt, nut, and
' washer embodying my invention; Fig. 2, a
plan of the same, and Fig. 3 a perspective view of the key.
Similar letters of reference indicate similar. parts of the invention in all the figures.
A is the nut, and B the washer, secured from turning by means of a screw, a, which passes through it into the object clamped belween the head of the bolt and the nut and washer. G is the key, one end of which is furnished with an inclined projection, b, hav ing a sharpened or V -shaped loweredge. The inclined V-shaped edge rests within a notch, c, of corresponding shape and inclination in thewasher. The key 0 passes through a slot,
d, in the nut, and is split at the entering end and spread, in order to prevent its being withdrawn after the nut is screwed to its place, and the desired tension placed upon the bolt.
The object of the inclined edge is to give firmness of bearing of the key in the notch, to compensate for the lack of surface of the key in contact with the washer, which this construction necessarily involves, the bifurcated end of the-key having tobe entirely above the upper surface of the washer to admit of its being spread, as described. The notch is cut in the washer by'means of a chisel or file, after its position is ascertained; consequently no peculiar description of washer is necessary.
Having thus described my invention, what I claim as new, and desire to secure by Let ters Patent of the United States, is-- In combination with the slotted nut A and notched washer B, the key 0, having the entering end bifurcated, and the driving end provided with the inclined and sharpened pro- 1 jec'tion b, adapted to rest within the notch c HERBERT LrviNesToN.
