SPECIFCATION forming part of Letters Fatemi;l No. 337,653, dated March 9, 1886.

Application filed December 7, 1885. Seral No. 185,011. (No model.)

To all whom, it may concern.-

Beit known that I, FRANKLIN l?. BnIsEL, a citizen ofthe United States, a resident ofthe town of Pottstown, county of Montgomery, State of Pennsylvania, have invented a new and useful Improvement in Look-Nuts, of which the following is a specification.

rlhis improvement is more particularly re lated to the class of lock-nutsintended for use upon the fish or splicing plates of railroad rail-joints, although adapted for general use as a lock-nut.

The object of the invention is to secure a positivelock for the nut, with anydesred tenx5 sion upon the bolt, so that the fish-plates may be drawn together with sufficient force to sustain the rail, yet will provide for a certain amount of sliding play of the rail upon the same, thus permitting expansion and con` 2o traction to take place without disturbing the alignment ofthe rails. It is well knownthat a certain amount of sliding play is desirable at the joint; but in all the lock-nuts with which I am acquainted the nut cannot be adjusted with sut'licient positiveness to retain the rails in sliding contact, they invariably becoming loose ina short time after adjustment. This desired result I attain by my improved mode of locking the nut, as will be 3o more clearly explained vwhen referring to the drawings herewith, forming a part of this specitication, in which like letters of reference indicate like parts.

Figure l represents an ordinary fish joint or splice with my improved nut-locking device thereon; Fig. 2, a cross-sectional elevation on the line of one of the splice-bolts; Fig. 3, a detached elevation of the combined lock-shell and washer, the protector-case 4o shown in section; Fig. 4, a detached elevation of the washer, showing one of the recessed ways with its keeper-hook. Fig. 5 represents an exterior end view of the locking-shellwith aportion of the nut-locking end removed to show the lockinglugs at the inner end of the shell and upon the interior face thereof. Fig. 6 is a vertical section of the l0cking-shell,showing the locking-lug and nutlocking aperture. 5o In the drawings, A represents the railroadl rail; B, the tish or splice plates; C, the usual bolts, having an enlarged body at O', to prevent turning, a head, C2, and hexagon or square nut C3. The nut-locking device is composed ofa washer, D, formed with a collar, D', an offset, D2, and bolt-aperture D3. An annular shell, E, passes freely over the body D of the washer, and the outer end is partially closed by a ring, E', having an aperture, E, cut therein for either a square or 6o hexagon nut, adapted to the bolt, and said aperture is cut slightly larger than the plan of said nut, so as to move freely over the same. A spiral spring, F, of suitable strength, preferably of brass wire, is adapted to slip over the body D of the washer, and on screwing up the nut C"s the springF will be compressed between the end ot' the annular shell E and the collar D. Diametrically opposite, upon the body D, and reverse to each other, re- 7o cesses or passages D* are out down to the level of the offset D2, and of the form shown, or its equivalent, producing a keeper-hook, D5, upon the body oi' the same. Lugs E3 E3 are placed diametrically opposite each other upon the inner face of the shell E at its inner end. Said lugs E3 are designed to project within the shell far enough to just clear the offset D2 of the washer D, and are made of asuitable size to pass freely into and around the passages D4 8c and finally lock beneath the keeper-hook D5. A case, G, is stamped out of tin-or light sheetiron, open at the front, and with an aperture, G', in the rear to pass over the bolt C. The washer D drops freely within the case, which serves to protect the combined parts from injury, and prevents tampering therewith by unauthorized persons.

To use the device, the fish-plates B and bolts C are placed upon lthe rail A. The washer D 9o has the spring F slipped upon the same, and resting upon the collar D. The shell E is then placed with its lugs E3 over the offset D-l and within the passages D4. The spring F is then compressed until the lugs E are brought in line with the horizontal passage, when the shell is partially turned toward the right, so as to throw the lugs within the same. This done, the spring is retained in a conlpressed condition, and washer and shell, virroo tually forming one integral piece, are placed within the case G and slipped upon the bolt C. The nut (Yi is now run down upon the bolt until it contacts with the end of the washer and drawn up tightly. A smart rap ofthe hammer is given to the head C of the bolt to insure snug work, andthe shell Eis again turned forward until the aperture El coincides with the nut 011 plan, and the lugs E* will have arrived in line with the inner vertical passage, when the resilience ofthe spring F will drive the shell E outward and the aperture El, sur rounding the sides of the nut c3, will lock the same therein. Aslight relaxation ofthe bolt tension is now given by a reverse turn to the uut, which at the same time lodges the lugs E" under the keeper-hooks D5, and there can be no further loosening` ot' the nut without the shell-lugs were shcared ott', which is not at all likely to occur,nnless intentionally done f'or a malicious purpose. To release the nut it is again turned to tighten up the same, which brings the lugs out from under the keeperhooks and in line with the inner vertical passage. The shell is then shoved inward, again compressing the spring F,and being turned to the left the lugs are caught as beiore in the horizontal passage, and the shell is held out of the way of the nut until the same is removed, or until it is desired to replace the same.

It will be apparent that the locking device may be used without the spring, as it' the shell is placed upon the \wasl1er,as descrihed,and at the proper time, j ust before relaxing` the ten sion ot' the nut upon the bolt, it is pulled toward the operator and made to coincide with the nut,as before. Then ou relieving thestrain upon the bolt the lugs will be thrown under the keeper-hooks,and nofurther release ot' the nut can take place. I prefer, however,to make use of the spring,as the outward movement of the shell toward the nut is at the proper ti me automatic, and the parts being held in close Contact thereby there is no noise created by loose parts as there would he without the use of the spring.

The washer D and shell E and the case G, if so desired,may all be constructed of castiron, being adapted to be easily molded and east of thesame,and little subsequent work upon them will be requisite, after the pieces leave the tumblingehurn, to lit them forimmediate applcation.

I am aware of much that has been done in the line of lock-nuts for railway splices, and believe that Ihave developed a new and novel lock, simple in its construction, positive in its action, and which may be repeatedly placed and removed without injury to the same.

As shown upon the splice, a portion of the 6 washer-collar is flattened to lie upon the foot of the fish-plate or on the foot ofthe railwhen the usual plain Hat splice-plate is used. 'This prevents the turning of the locking device while the nutisbeing tightened up or released; 6

but the nut-locking device is applicable to many other purposes, aud various modes may be adopted to prevent turning-such as pins cast upon the outer face of the washer and countersunk recesses punched or formed in the 7o rails Yet will not be sufiicient to iroduc-e in- 8O jurions looseness of' the several parts.

Having shown the eonstructiomuse, and advantages o1" my improved nut-locking device,

I desire to secure by Letters .Patent the following claims upon the same: 8 l. As an improved nut-locking device, an

annular shell, E,havinglugs E at its inner interiorsnri'ace and in its outer end an aperture, E, conforming with and adapted to receivethe nut C* ol" the bolt C, in combination 9 with a body-washer, D, with collar D', recesses D, and keeper-hooks D5` adapted by perforation D:i to slip over said holt, and a spring, F, all arranged and adapted to be operated together substantially as shown, de- 9 scribed, and for the purpose specified.

2. In combination with a nut-locking dcvice consisting ot a perforated body-\\'aslier, D, with passages D" and keeper-hooks D5, formed upon or within the same, and an an nular shell, E, having a nut-aperture, E2, and lugs E, adapted to move within the passages D" and lock beneath the keepers D, as described, an outer open case, its inner end perforated for the bolt G, said case adapted to reeeivethe collar D' of the washer D, and to conceal and protect the spring F and contacting parts of washer and shell in the manner as shown,and for the purpose set forth.
