NUT-LOCK.
Specification of Letters Patent.
Patented March 2, 1909.
Application filed February 28, 1908. Serial No. 418,186.
T 0 all whom it may concern:
Be it known that l, DANIEL M. KENYON, a citizen of the United States, residing at Bradford, in the county of McKcan and State of Pennsylvania, have invented new and useful Improvements in Nut-Locks, of which the following is a specification.
My invention relates to improvements in nut-locks for bolts, wherein the nuts are used in pairs located side by side upon a single bolt, each of said. nuts abutting against the other; and its" object is to prevent the nuts from being jarred or shaken loose.
It consists in so shaping the opposing surfaces of said nuts that the same may be wedged together without compressing or clamping the thread of the screw-bolt upon, which the nuts are situated.
It further consists in the several features and modifications hereinafter more specifically described and claimed.
I am aware that it is old to form a bolt having the threaded portions thereof in two parts, which are threaded in opposite direc.
the nuts have been secured together in various manners to prevent the same from turning upon the bolt. In all cases, however, where the conical follower has been used the same has been so constructed as to be compressed upon the thread of the bolt, and be thereby secured from turning upon the same. In no instance, so far as I am aware, have two nuts been wedged together and secured without compressing the threads of the bolt. I have found in actual practice that the compression or clam ing of the thread is a serious objection; for while the lock may be secured, it is impossible to remove the two nuts with out destroying the thread'of the bolt and the nuts,the said device being thereby rendered inoperative for further use.
The purpose of my invention is to provide a nut-lock wherein the nuts composing the same may be removed without injury to. the thread of the bolt, and may be used again and again if desired. It frequently occurs that when bolts of this character are used for securin fish plates of the rails of a common railroa or on parts of the rolling stock there of that it becomes necessary from time to time to break up the union of the nutlock in order that repairs may be made. In such instances the nut-locks having to be replaced gives rise to a large item of expense, and
there has existed for a great many years a demand for a lock which cannot be shaken loose and can be removed without injury to the threads.
Referring to the drawing in which similar numerals of designation refer to similar parts throughout the several views :Figure 1 is a longitudinal section of my improved nutlock, showing the two nuts wedged together upon the bolt. Figs. 2 and 3 are longitudinal sections of modifications of the nuts forming the nut-lock and their position on the bolt. Figs. 4, 5 and 6 are plan. views of the outer 4 nuts shown in Figs. 1, 2 andS respectively.
In the drawing, ,the bolt 7 is shown constructed in a well known manner for the class of nut-lock to which my invention belongs,- the threaded portions 8 and 9 of said bolt be ing of different diameter and threaded in op posite directions. Each of said parts bears thereon nuts 1 land 12 which are threaded to engage the same, and can beturned so as to come in contact one with the other, and by being wedgedtogether in the manner hereinafter described maintain themselves from movement, by reason of the friction or pressure between their opposing surfaces. In Figs. 1 and 2, the outer nut 12 preferably contains the conical or wedge shaped depression 13, which is formed to engage with the conical or wedge shaped follower 14 on the inner nut 11. In all cases the follower 14 is made of suchthickness that it cannot be compressed to any substantial extent upon the threads of the. bolt by reason of being wedged into theopening 13, the edges of which are preferably of such thickness that they may be forced outwardly, but at the same time strongly gri the follower 14. Preferably the said to lower 14 is made slightly greater than the depression 13,in order to insure the same bcingwedged together in an effective manner.
In Fig. 3, the follower and depression are shown somewhat modified, but obviously embody the principle of my invention. In this View, however, the incompressible follower is shown on the outer nut 12 and enroe gages the conical depression in the inner nut 11 formed within the walls of the ring shaped ridge 15. The recess 16, formed between the follower and an extension of the nut 12, en-
es with the ridge 15 and serves to hold the gs wall of said depression from undue expansion and strain.
In practice I first place the inner nut in. position, and then securing the same against tu I gradually turn the outer jam-nut upon 1; e-portion 9 until the nuts are tightly wecllvged together. I
hat I claim and desire to secure by Letters Patent is 1. A nut-lock, consisting of a threaded bolt, two nuts threaded to engage the same, one of said nuts having a continuous tapering projection extending around its threaded opening, and the other having a recess the wall of which is continuous and adapted to vengage said projection and shaped to be cess in one end of thesame, and the other nut having around its threaded opening a continuous annular conical projection adapted to engage said recess and shaped to be wedged therein when said nuts are turned to approach each other, the interior wall of said projection being threaded to be continuous one direction and partly in the opposite direca tion, two nuts respectively engaging with said threaded parts, one of said nuts having a tapering conical depression in one end of the same, and the other nut having a tapering conical follower of slightly greater diameter than said depression and adapted to engage the same when the nuts are turned to approach each other, the interior of saidiollower being threaded to be continuous with the interior threaded opening of the nut upon which it is carried, and both said follower and depression being so situated as not to compress the threaded portion or said bolt when the nuts are turned together.
In testimony whereof l have hereunto set my hand in presence of two subscribing witnesses, this eighth day of February 1908.
