NUT-LOCK.

Specification of Letters Patent.

Patented Jan. 5, 1909.

Application filed January 28, 1908. Serial No. 413,052.

To all whom it may concern:

Be it known that 1, ROBERT L. a citizen of the United States, residing at Springfield, in the county of Greene and State of Missouri, have invented certain new and useful Improvements in Nut-Locks, of which the following is a specification, reference being had to the accompanying drawings.

My invention relates to improvements in nut-locks for the bolts of rail-joints and other structures.

The object of the invention is to provide a simple and practical nut-locking device which will be inexpensive in construction, easy to apply and remove and very effective for the purpose intended.

With the above and other objects in view, the invention consists of the novel features of construction and the combination and a1- rangement of parts hereinafter described and claimed, and illustrated in the accompanying drawings, in which F i ure l is a side elevation of a rail-joint showing the application of my invention thereto; Figs. 2 and 3 are respectively, horizontal and vertical sections taken on the planes indicated by the lines 22 and 33 MANGAN,

in Fig. 1; Fig. 4 is a perspective view of the washer or fish-plate; and Fig. 5 18 a similar view of the locking plate.

In the drawings I have illustrated my invention embodied in an improved rail-joint which consists of the meeting ends of two track rails 1, 2, two fish- plates 3, 4 and a plurality of transverse bolts 5. The rails l, 2 are of the usual form and have in their webs openings or slots to receive the bolts 5 and which aline with similar openings in the fish-plates or washer- plates 3, 4. The open ings in the fish-plate 3 have squared outer portions to receive squared portions formed upon the bolts adjacent to the heads of the latter. Each of the latter has a vertical portion 6 which is apertured and adapted to fit against the webs of the track rails, and a horizontal or angular lower portion 7 adapted to rest upon the base flanges of said rails. The outer edges of the lower or base portions 7 of the fish-plates project beyond the edges of the base flanges of the rails and are notched as at 8 to receive spikes which fasten the rails upon the cross ties.

The washer or fish-plate 4 which is preferably upon the outer side of the track rails is formed at one end of its vertical or upright which formed cent to the opposite end of the plate 4 is a horizontally disposed projection or lug 11 which projects outwardly from the vertical portion 6 of said plate at a point adjacent to its end and which is formed adjacent to its outer end with a vertical aperture 12. Said lug 11 is preferably made independent of the fish-plate 4 and is secured therein by reducing its inner end to provide a stop shoulder, passing the reduced end through an opening in the fish-plate so that the shoulder engages the outer face of the latter, and then upsetting the inner extremity of the lug in a flared or enlarged portion of the opening in the fish-plate, as clearly shown in Fig. 2.

The nuts 13 of the bolts 5 are screwed up against the outer face of the washer or fishplate 4 and are adapted to be locked against rotation by a locking member or plate 14 formed with a plurality of openings 15 adapted to receive said nuts. The locking plate 14 is removably secured upon the plate 4 by forming at one of its ends an outwardly curved or bent tongue 16 which is adapted to be inserted in the opening 10 in the extension or lug 9; and by forming adjacent to the other end of the locking plate 14 a slot or opening 17 which receives the horizontally or laterally projecting lug 11. The opening 17 is formed a short distance from the end of the locking plate 14 and the latter is made slightly longer than the washer or fish-plate 4 so that said end of the locking plate projects beyond the adjacent end of the plate 4 in order that the locking plate may be readily removedfrom the nuts by insorting an instrument under said projecting end of the locking plate. The locking plate is retained in position upon the nuts by the engagement of the tongue 16 with the extension or lug 9 and by inserting a split pin or key 18 in the vertical aperture 12 in the lug 11.

From the foregoing it will be seen that my improved nut-lock is especially well adapted for locking the nuts on a series of bolts as in a rail-joint but it will be understood that it may be adapted for other uses and for looking a single nut or a greater or less number than that illustrated.

It will be further noted that the device is exceedingly simple and inexpensive in con- Having thus described my invention what,

I claim is The combination with the meeting ends of two rails having transverse openings in their web portions, of angular fish-plates having base portions to restupon the base flanges of the railsand formed With notches in theirouter edges to receive fastening spikes, each of'said fish-plates also having a vertical portion to engage the webs of the railsand formed with openings to register with the openings in the webs of-the rails, the openings in the vertical portion of one fish-plate having squared outer portions, the vertical portion of the other fish-plate being formed atone end with an extension bent outwardly and provided with an opening, and at its other end with an opening inner portion, an apertured lug having-a reduced end secured in the last mentioned opening in said fish-plate, transverse bolts that it may bequickly and easily having a 1 flared I passed through thecalining openings in the fish-plates and rails and having squared portions adjacent their heads to engage the squared portions of the openings in one of the fish-plates, nuts upon the projecting threaded ends of said bolts and screwed against the outer face of the other fish-plate, a locking plate formed intermediate its ends with openings to receive said nuts, one end.

of said locking plate being formed with a reduced tongue bent outwardly and adapted to enter the opening in the extension on said fish-plate, the other end of said locking plate being formedwith an opening to receive the apertured lug upon said fish-plate, and a split pin arranged in the aperture in said lug to retain the locking plate in position, substantially as shown and described.

In testimony whereof I hereunto affix my signature in the presence of two witnesses.- ROBERTL. MANGAN. Witnesses:
