ALBA F. DIMOND, OF ORESSON, PENNSYLVANIA, ASSIGNOR OF ONE-HALF' His RIGHT 'ro ALBERT FORD, or SAME PLAoE.
IMPROVEMENT IN NUT-LCKS.
Speeification forming part of Letters Patent No. 158,256, dated December 29, 1874; application filed November 13, 1874.
To all whom 'it may Gomera:
Be it known that I, ALBAN F. DIMOND, of Oresson, in the county of (Jambria and State of Pennsylvania, have invented certain new and useful Improvements in Nut and Bolt Locks;-and I 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 pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification, in which- Figure l is a front view of my invention. Fig. 2 is a central section of nut. Fig. 3 is a side view of bolt. Fig. 4 is a side view of key. Fig. 5 is a sectional view of bolt and nut, with key applied. Figs. 6 and 7 are views of modifications.
This invention relates to that class of nutlocks wherein the bolt, as well as the nut, is rigidly seeured by the same means, and both efi'ectually prevented from turniu g or workin g loose. For this purpose I take any kind of bolt and nut, groove both longitudinally, cutting across the threads. The groove in the nut is made deeper at one end, into which fits a shoulder on the looking-key loosely, in order that it may slide in it a distance of half a thread, so that when adjusted the raised points on the serrated' edge of the groove in i the bolt will meet that on the key, and thus present an mpassible barrier to the revolution of the nut, reference being had to the accompanying drawings, where like letters refer to like parts. i
A is a bolt, and B a nut, both of any description. D designates the lockingkey, which may be round, square, dovetailed, or any other form iu transverse section, and the grooves a in the bolt, and Z) in the nut, made to correspond. The groove a is of the same depth throughout, while that in the nut is deepened at one end to a lengthl sufficient to' permit the sliding of the looking-key a distance of half a thread. The looking-key is threaded on one side to the same gage as the nut, and is formed with two Shoulders, one to keep it from coming out, which is designated c in the drawings, and the other, d, serves as a catch for the malleable wire e. Thls Wire is designed to enter under the shoulder (Z when the key is thrown out of gear with the thread on the bolt. lt is preferably of malleable metal, so that the annoyance incident upon holding back a spring while adj usting may not arise, but a spring or equivalent may b'e used. Made thus', all that is necessary to change the position of the nut is, to push the end of the Wire from under the shoulder d, while :adjust ing the key, and replace it when done. The advantage of this is, that having no normal position, it will not have a continual tendency to return to it.
The bolt may have one, two, three, or more grooves ready cut in it, or where absolute rigidity is required at the tightest point, the nut may be turned down on the bolt till this point is reached; then the bolt marked, and
after the nut is removed the groove is cut by.
As a modification of my invention, the locking-key may be formed with a stud between the 'ends, fitting into a slot in the nut-groove, or the devices may be reversed, the shoulder or stud on the nut, and the slot on the key.
The method of Operating is as follows: The groove being ready in the bolt, (which may be done in the manufacture,) place the key in the groove of the nut with the threaded side corresponding and coincidin g with the threads in the nut; now, screw down the nut, and, when looking is desirable, simply lift the key a half thread by means of the shoulder d, push the malleable wire under the same, and the l'ocking is complete. To unloek, withdraw the end of Wire from under the shoulder (Z of the key, restore the latter to coincidence with the nut-threads, and the nut may be at once unscrewed.
The bolts and nuts may be ready grooved I in the manufacture, or, in especial cases, this may be done by a tool for that purpose.
