NUT-LOCK.

SPECIFICATION forming part of Letters Patent No. 350,827, dated October 12, 1886.

Application filed November l2, 1865. Serial No. 1923577.

To ali whom, t may concern.-

Beit known that I, W TLLIAM SHE l xroN lili-in- Ris, a citizen of the United States, residing at Arlington, in the count)Y of Ballard and State of Kentucky, have invented a new and useful Improvement in Nut-Locks, of which the following is a specification, reference being had to the accompanying drawings.

My invention has relation to improvements in nut-locks; and it eonsists in the peculiar' construction and combination of parts, snbstantially as hereinafter fully set forth, and specifically pointed ont in the claims.

The primary object of my invention is t0 provide a nntloek which shall he easily and readily applied to and removed from the se curing-bolts, and to provide means whereby a longitudinal strain or pressure is exerted on the bolts to keep them l'rom rattling in their sockets.

A further object of my invention is t0 provide means whereby each nut can be locked in position independentlyof the other, thus permitting ofthe removal of one nut without disturbing the other nut; and it has further for its object to combine simplicity with strength and durability of construction and thorough effectiveness of operation.

In the annexed drawings, Figure l is a side elevation ot' a nntlock embodying my invention. Fig. 2 is a transverse vertical sectional View on the line :c ,r of Fig. l. Fig. 3 is a detail perspective view of the supporting-plate, together with the pivoted locking-arms. Fie'. i is a view of one of the bolts with its attached spring and protectingsleeve.

Referring to the drawings, in which like letters of reference indicate corresponding parts in all the figures, A designates the rail, 2B, the sh-plates, C, the bolts passing through t-he'sh-plates and rail, and D the securingnuts fitted on the outer ends of the bolts.

E designates a washer fitted over each of the bolts and bearing against the outer vertical face of one of t-he fish-plates, and F a coiled or helical spring fitted over each of the bolts, and bearing at one end against the washer E and at its opposite end againsta supporting plate, G, extending from and fitted over the 'bolts C. The securing-nuts D bear against the arms from movement in a vertical plane.

outer' face of the supportingplate G, and are each engaged by a looking-arm, H, two of which are provided and pivoted on a common center or pin, lr, arranged between the two nuts. The outer end of each locking-arnrH is provided with a slotted head, r, which fits over the side faces of the nut, and thus se` curely locks the same in position from turning. The inner ends of each locking-arm are bent, as shown, t-o adapt them to move past 6o each other at their inner ends, and said arms move in a plane above the nuts and supporting plate or bar (l.

l designates a sleeve or thimble fitted over the bolt and the coiled spring, to protect them from rust and the action ofthe weather.

To apply my improved nut-lock the boltsK are first inserted through the fish-plates and rail, the washers E then fitted over the bolts and against one of the fish-plates, the coiled 7o springs and sleeves are now placed thereon, the securing-bar fitted over the bolts and pressed or forced inwardly against the tension or force of the springs by means of the nuts D bearing against'the same, and, finally, when sut'ii- 75 cient force is exerted on the bar, the lockingarms H are engaged with the nuts.

By means of the coiled springs bearing against the bar or plate and the securingnuts, a longitudinal strain is exerted on the bolts, So which serves to keep them from movement and rattling in their sockets, and when the arms H engage the nuts the latter are effectually prevented from turning and becoming detached from the bolts. 8 5

Each nut-locking arm can be disengaged from its nut independently of or without its fellow arm, and the nuts can thus be secured in place independently of each other and removed from the bolts.

In order to detine the nature, scope, and advantages of my invention I would state that heretofore it has been proposed to provide a nut-lock with looking-arms pivotcd tothe fishplate and having a notch and plate adapted to engage a nut, a locking-plate arranged to bear on the contiguous pivoted ends of the' locking-arms, and a screw to secure the plate in place and prevent the pivoted nut-locking I Too am also aware that a nut-lock has been provided which comprises two arms or plates, the outer ends of which are enlarged and provided with flanges to engage the upper and lower faces ot" two adjacent nuts, while the inner ends of the arms are pivoted together so as to move in a horizontal plane, and have openings therein that arein alignment with each other when the device is adjusted in place, so that 1o apin can be passed vertically through the same to hold the arms rigidly together and against movement. In the device first above referred to the locking-arms are pivoted directly to the -ish-plates, and they cannot be i 5 adj usted laterally to engage th'e nuts very squarely and firmly when the nuts lie at a distance from the tish-plate; and in the latter device above.referred to the arms are wholly supported on the nuts, and are thus supported 2o entirely independent of the fish-plate and have no connection therewith. My invention differs from these devices in the fact that I employ a plate that is 'loosely mounted on the bolts, and which is passed normally away from the fish-plates by springs coiled around the bolts and interposed between the movable plate and the sh-plate. On this movable I springpressed plate my nut-locking arms are pivoted by aI single bolt, and `these arms are 3o adjustable independently of each other over the nuts that are screwed on the free ends of the bolts, and serve to retain the movable plate in place and to prevent the bolts from rattling in their sockets.

The advantage gained by my device 'over the constructions hereinbefore mentioned lies in the fact that when the nuts are turned on the bolt the movable spring-pressed plate is also adj usted so that the nut-locking arms al- 40 ways occupy the same relative position to the nuts, and are thus maintained in a position so that they can squarely and firmly engage the nuts to lock them in place.

I am also aware that it is not new to provide a bolt of a nut-lock with a springv that lies between the fish-plates and the nut to prevent the bolt from rattling, nor to provide a cliambered washer having a coiled spring to ally-movable plate, whereby when the nutsr are adj usted the spring-pressed plate and the nut-locking arms will also be adjusted to adapt the arms to firmly engage the nuts, substantially as described.

2. In a nut-lock, the combination of the rails, the fish-plates, the through-bolts, a plate, G, supported on two adjacent bolts and movable thereon laterally of the rails, the coiled springs F, encircling the bolts and bearing against the lish-plates and the laterally-movable plate, thc sleeves I,inclosing the springs and bolts, the nuts D, bearing against the plateG to retain the same on the bolts, and the locking-arms H, carried by the laterallymovable plate and pvoted on a pin, h, common to both arms, and further provided with the enlarged notched ends h', substantially as described. p

In testimony that I claim the foregoingas my ownI have hereto affixed my signature in presence of two witnesses.
