GAR LOCK FOR MINE CARS Filed July 22, 1935 INVENTOR ATTORNE Patented May 5, 1936 UNITED STATES PATENT OFFICE Application July 22,

2 Claims.

This invention relates to looks or fasteners for mine cars to prevent accidental running away of cars when left unattended, and has for the primary object the provision of a device of this character which may be readily applied to a rail of a track and a wheel of a car to prevent accidental travel of the car over the track and which may be easily and quickly actuated to free the Wheel of the car and should the device, through inadvertency be not entirely disengaged from the wheel it will be automatically disengaged therefrom by the turning of the wheel so as not to dam-.- age the device on the wheel.

With these and other objects in view, this invention consists in certain novel features of construction, combination and arrangement of parts to be hereinafter more fully described and claimed.

For a complete understanding of my invention, reference is to be had to the following description and accompanying drawing, in which Figure 1 is a fragmentary transverse sectional view showing a rail engaged by a car wheel with the latter secured in said rail against rotation by a fastener constructed in accordance with my invention.

Figure 2 is a fragmentary side elevation illustrating the same.

Figure 3 is a side elevation, partly in section, illustrating the fastener.

Figure 4 is a fragmentary edge view illustrating one of the arm portions of the fastener.

Referring in detail to the drawing, the numeral I indicates a substantially U-shaped clevis including a bight portion 2 and parallel arms 3 and 4. The arm 3 is of a greater length than the arm 4 and has formed at its free end an eye 5 provided with a circular-shaped opening 6. The free end of the arm 4 is enlarged and bifurcated to form apertured ears I forming a part of a hinge. A lug 8 has one end shaped to form an apertured ear 9 received between the ears 1 and pivoted thereto by a rivet ID. The lug 8 is free to hinge on the arm 4 and a portion thereof is offset, as shown at I I, and provided with an elongated slot [2. A pin l3 extends through the slot l2 and one end is enlarged to form a head l4 of a size which will not pass through the slot l2. The pin l3 has a limited pivotal movement 1935, Serial No. 32,637

to the lug 8 due to the slot I2. The other end of the pin is burred, as shown at l5, capable of passing through the opening 6 of the eye 5.

In use the clevis l is placed under a rail l6 of a track with the arm portions 3 and 4 arranged 5 vertically at opposite sides of the rail. The pin I3 is then passed through the wheel and through the opening 6 of the eye 5, as shown in Figure 1, so as to secure the wheel against movement over the rail. To release the wheel, the pin is with- 10 drawn from the opening 6 of the eye 5 and the lug 8 may swing downwardly totally disengaging the pin from the wheel. However, should the lug 8 fail to swing downwardly and the pin assume the position shown in dotted lines in Figure 1, it will become automatically disengaged from the wheel by the turning of the latter. The automatic disengagement of the pin from the wheel and from the dotted line position, as shown in Figure 1, is permitted by the slot l2 and the hinge between the lug and the clevis.

A device of the character described is easily applied to a rail and a wheel of a car and will effectively secure the wheel against movement over the rail and due to its automatic disengagement from the wheel or from the position shown in dotted lines in Figure 1, will permit the device to last indefinitely owing to the fact that it will not be injured or damaged.

Having described the invention, I claim:

1. A wheel fastener comprising a clevis arranged under and transversely of a rail of a track and having one end apertured, and a pin pivotally and slidably connected to the clevis and adapted to extend through a car wheel and through the aperture for securing the wheel against turning on the rail.

2. A wheel fastener comprising a clevis arranged under and transversely of a rail of a track and having one end apertured, a lug hinged to the other end of the clevis and having a slot, a pin extending through the slot to pivotally and slidably connect said pin to the clevis, said pin adapted to be extended through a car wheel and through the aperture and has one end burned and its opposite end enlarged to prevent the pin from moving out of the slot.
