' SAFETY APPLIANCE.

Application filed May 7,

This invention aims to provide a simple means whereby the nuts on the bolts which hold the ends of a pair of railroad rails together, may be held against rotation. The invention aims to provide novel means where- .by the locking device for the nuts may be assembled with and held upon the angle bar. through which the bolts which carry the nuts pass. 1

It is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the invention appertains.

With the above and other objects in view, which will appear as the description proceeds, the invention resides in the combina-' tion and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.

In the accompanying drawing 1- Figure 1 shows in side elevation, the meeting ends of a pair of rails wherewith the device forming thesubject matter of this application has been assembled;

Figure 2 is a transverse section; and

Figure 3 is a perspective view of the lock- 111g device, parts being broken away.

In the drawings, there is shown a pair of rails 1, each including a ball 2, a web 3, and a flange 4. The angle barsare marked generally by the numeral 5, each angle bar including a first flange 6, and a. second flange 7 The flanges 6 and 7 are disposed on opposite sides of .t is web 3 and are engaged at their upper. edges beneath. the ball 2 of the rail. The second flanges 7 rest upon. the flange 4 of the rail as shown in Figure 2 of the drawings. The bolts 8 pass through the web 3 and through the flanges 6 oil the angle bars 5 in a way well understood by anyone. The construction of the device is such that, in the absence of the structure forming the subject matter of this application, a track wrench can be put on the nuts 9 of the bolts 8, thereby to rotateand detach the nuts.

In carrying out the invention, there is .provided a locking device which is shown in Figure 3, the same being made out of a rod or wire having some resiliency.- The locking da 1928. Serial No. 275,881.

yond the arms 11 The flanges 6 are provided on their inner surfaces with longitudinal grooves orseats' l4.

In practical operation, the body 10 of the locking device is placed in the angle between V the flanges 6 and 7 of one of the splice bars, and when the body of the locking device is so located, the nuts 9 cannot be rotated. The arms 11 have resiliency enough so that the inner ends of the heads may be engaged in the isjeats or grooves 14 at the ends of the angle ars.

In this way, the locking device is held in place with the body 10 thereof underneath the nuts and holding the nuts securely against rotation. The arms 11" extend inwardly across the ends of the angle bars as shown in Figure 2, and because the inner ends of the heads 12 project toward each other, beyond the arms 11 as clearly shown in Figure 1, the inner ends of the heads 12 may be engaged in the seats 14, as has been explained hereinbefore. When it isdesired to detach the locking device, this may 'bedone by placing a tool in'either of the heads 12 and springing the arms 11 lengthwise of the rails until the inner end of the head 12' which is being opera-ted upon, is disengaged from the corresponding seat 14.

Having thus described the invention, what is claimed is I In a device of the class described, a splice' bar including flanges, a bolt extended through one of the flanges, a nut on the bolt, a locking member extended longitudinally of'the angle defined by the flanges of the splice bar, and k located between the other of said flanges and the nut to hold the nut against rotation, the

locking member being provided-at its ends with heads engaged yield ably behind the first specified flange of the splice bar, the heads having openings extended beyond the ends of the splice bar and adapted for the reception of a prize tool.

In testimony that I claim the foregoing as my own, I have hereto afiixed my signature.
