NUT LOCK;
Application filed March 9, 1923. Serial No. 624,040.
To all coho m. it may concern:
Be it known that 1, CHARLES R. COCHRAN,
a citizen of the United States, residing at Jerome, in the county of Yavapai and State of Arizona, have invented certain new and useful Improvements in a Nrut Look, of which the following is a specification.
The present invention relates to nut locks and has for its principal object to improve upon the structure disclosed in Letters Patent No. 1,373,489 issued to me on April 5, 1921. Y
Another object of the invention is to generally improve upon nut locks of this nature by providing a simple and efficient structure which is reliable in operation, durable, inexpensive to manufacture, and well adapted to the purpose for which it is designed.
With the above and numeroustother ob jects in view as will appear as the description progresses, the invention resides in certain novel features of construction, and in the combination and arrangement ofparts as will be hereinafter more fully described and claimed.
In the drawing: Figure 1 is an elevation of the threaded portion of a bolt showing a nut and my lock thereon in section,
Figure 2 is a front elevation of the lock showing the bolt in section taken substantially on the line 2-2 of Figure 1 looking in the direction of the arrow,
Figure 3 is a rear elevation of the lock, Figure 4 is a plan view of the blank from which the lock is formed,
Figure 5 is a section therethrough on line 55 of Figure 4,
Figure 6 is a front elevation of a modified form of the lock,
Figure 7 is a section taken on the line 77 of Figure 6.
Generally speaking the invention consists of a lock having oppositely arranged segments to thread on and engage a bolt. When the lock is screwed on to the bolt it first comes into oblique contact with the nut, and then tightens to a locked position by forceful turning with a wrench to a closer Contact with the nut, so as to be positioned substantially parallel with the face of the nut; and forces the segments to a smaller diameter or distance in relation to each other and cons uently cause the segments to bite into the olt at the base of the thread groove.- The lock is adapted to be withdrawn from its locked position by turning in an opposite direction with the same power applied in the locking of the same.
Referring to the drawing in detail it will be seen that 1 designates the body of a bolt having the usual threaded portion 2. The usual formof nut -3 is adapted to be applied to this threaded portion 2. My lock consists of a ring or washer 4 having an opening 5 therein. The circumf erence of this opening 5 which would be described by the line 6 is larger than the circumference of the apex of the threaded portion 2.
segment 8 is out of alignment with the body of the lock washer 4 being pitched to accommodate the pitch of the thread 2 of the bolt 1 and is therefore a thread segment. I A second segment 9 projects from the body of the lock washer 4 into the opening 5 and is preferably diametrically opposed to the segment 8. The length of this segment 9 is greater than that of the segment 8 the incisions 10 being made into the lock washer for this purpose. This segment 9 extends well within the circumference 7 when coplanar with the body of the lock washer but when bent outwardly toward the forward" side of the lock washer as shown in Figure l the diameter between the segment 9, and the segment 8 would be 7 equal to the diameter of the circumference 7 or equal to the diameter of the thread groove of the bolt. It will thus be seen that the lock washer may be threaded upon the bolt in an oblique position in relation thereto. An engaging lip 11' is formed on the lock washer on the outer edge thereof adjathread segments 8 and 9 to ,bite into the threaded portion 2 of the bolt.
The modification disclosed in Figures 6 and 7" includes the lock washer 4, the segment 8 projecting into the opening 5. The segment 9 is functionally equivalent tothe segment 9 described with the previous,
vention which will give in practice satisfactory and reliable results, and it is to be understood that the same are susceptible of modification in various particulars without departing from the spirit orscope of the invention or sacrificing any of its advantages.
Having thus described my invention what A I claim as new is 1. A nut lock comprising a ring or washer having an opening, a thr ad seg ment projecting in the opening coplanar with the ring or washer, a second'thread segment projecting in the opening out of alinement with the ring or washer, and a nut engagingvlip formed on the perimeter of the ring or washer and bent over a space of the ring or washer opposite to that from which the second segment extends.
2. A nut lock comprising a ring or washer having an opening, a thread segmentprojecting from the edge of the opening toward the center thereof and coplanar with the ring or washer, a second thread segment projecting from the edge of the opening toward the center thereof and disalined from the ring or washer so that its end is disposedon one side thereof, and a nut engaging lip formed on the perimeter of the ring and bent so as to extend over the other side of the ring or washer.
In testimony whereof I affix my signature in presence of two witnesses.
CHARLES R. COCHRAN.
