3 Claims.

This invention relates to car stops, and its general object is to provide a device of that character which is primarily designed for use in mines to arrest the motion of cars, the device being attachable and removable with respect to a track in an easy and expeditious manner, but casual removal or displacement is practically impossible, and it includes a scotch or chock block which can be moved into and out of the path of a car wheel, with minimum eifort on the part of the operator, and without any possibility of injury to the operator, as the device can be either hand or foot operated at a point remote from the scotch block.

Another object is to provide a car stop that is simple in construction, inexpensive to manufacture, and extremely efiicient in operation, use and service.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawing and specifically pointed out in the appended claims.

In describing the invention in detail, reference will be had to the accompanying drawing wherein like characters denote like or corresponding parts throughout the several views, and in which:

Figure 1 is a top plan view of my device attached to a rail, with the scotch block in use.

Figure 2 is a side elevation thereof.

Figure 3 is a similar view with the scotch block out of use.

Figure 4 is an end view looking toward the right of Figure 1.

Figure 5 is a detail perspective view of the lever for applying the scotch block to the rail.

Figure 6 is a similar view of the lever for removing the scotch block from the rail.

Referring to the drawing in detail, it will be noted that the base I is of relatively narrow fiat elongated configuration and formed on and rising from adjacent one end 2 of the base is a rail engaging block 3 that is inclined toward said end at an acute angle relative to the base, to overhang the same, to provide a seat between the under face of the block 3 and the base for fittingly receiving one side portion of the flange of the rail, as clearly shown in Figures 2 and 3, which also illustrates that the vertical side face of the block is of a height to' fit and bear againt the rail web throughout the height of the latter. Cooperating with the rail engaging block 3 for detachably securing the device to the rail is a locking tongue 4 that is pivotally secured to a lug 5 formed on the end 2 of the base, and providing an abutment shoulder for the edge of the opposite side portion of the rail flange, the tongue bearing against the upper face of the flange when in use, and when moved on its pivot out of use, the device can be removed from the rail, as will be apparent.

Straddling the rail engaging block is a bifurcated lower end of an arm 6 that has its bifurcae tions mounted on a pivot pin 1 which extends through the block 3 adjacent .to its juncture with the base. The upper end of the arm is beveled, and welded or otherwise fixed thereto is a scotch block 8 that projects beyond the beveled end to provide an outwardly extending portion, as shown in Figure 3, and the block 8 is formed with curved wheel engaging faces 9. By that construction, it will be seen that the arm 6 is mounted for swinging movement for applying and removing the scotch block with respect to the head of the rail, and when applied thereto, the block is mounted on the head for disposing the faces in the path of car wheels for chocking the same.

Formed on the end H] of the base is, a pair of spaced parallel uprights H, and a bar like lever I2 is pivotally mounted intermediate its ends between the uprights by a pivot pin I 3 arranged adjacent the upper ends of the uprights for normally disposing the lever at an upward inclination from the base, with its handle or foot engaging portion l4 extending outwardly a considerable distance beyond the uprights, while the inner portion of the lever is flattened and bent upwardly adjacent its inner end to provide a foot [5 that is engageable with the arm and the outwardly extending portion lb of the scotch block to swing the arm on its pivot 1 for applying the block on the head of the rail, as best shown in Figure 2. The inner portion of the lever I2 is normally seated in a slot l1 extending along the longitudinal center of the base, from the rail engaging block 3 to and through the end I0, and when the scotch block is not in use, it rests upon the lever l2, as shown in Figure 3.

A lever is is provided for moving the scotch block, from the head of the rail, and the lever I8 is formed with a head I9 mounted for pivotal movement on the pin 1 for disposal laterally of the arm 6, and the lever I8 like the lever l2 extends longitudinally of the base I and beyond the end H] thereof to provide a handle or foot engaging portion 29. Secured to and extending laterally from the inner face of the head I9 is an abutment pin 2| that is disposed in the path of r the arm 6, for the latter to engage the same and lift the lever l8 from its normal lower position, parallel with the base, as shown in Figure 3, to its elevated position of Figure 2, when the arm is moved for disposing the scotch block on the rail, with the result it will be seen that upon depressing the lever l8 when the scotch block is on the rail, the abutment pin 2| will swing the arm 6 on its pivot and remove the block from the rail.

From the above description and disclosure in the drawing, it will be obvious that either lever can be actuated by the foot of the operator, and upon depressing the lever I2 the scotch block is applied to the rail while the lever l8 acts to remove the block from the rail.

It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construdtio'n and in the combination and arrangement of the several parts, provided that such changes fall within the 'scope or the appended claims.

What I claim is:

1. A car stop comprising an elongated base to underlie a rail, a rail engaging block fixed to and overhanging the base adjacent one end thereof to cooperate with the base to provide a seat for the flange of the rail, pivoted means engageable with said flange for cooperation with said block for locking the base to the rail, an arm pivotally secured to said block, a scotch block fixed to the arm to be carried. thereby for swinging movement to be disposed'on and off the rail, a pair of spaced uprights formed on the base at the opposite end thereof, a lever pivoted between the uprights and engageable with the arm and scotch block for applying the latter to the rail, a second lever having one end pivoted to the pivot of the arm and being normally disposed in a lowered position paralleling the base, a pin at the pivoted end of the second lever and arranged in the path of the arm for the latter to elevate the second lever when the scotch block is applied to the rail, and said pin being engaged with the arm when the scotch block is in applied position, whereby upon moving the second lever to its lowered position, the scotch block will be removed from the rail.

2. A car stop comprising a base, means for detachably securing the base to a rail, an arm pivotally connected to the base, a scotch block carried by the upper end of the arm, a pivoted lever carried by the base for engaging the inner face of the arm for throwing the same outwardly away from the rail, and a. pivoted lever carried by the base and engaging the scotch block for throwing the same upwardly on the rail.

3. A car stop comprising a base, means for detachably "securing the base to the rail, an arm pivotally mounted on the base, a scotch block carried by the outer end of the arm, a lever pivotally mounted on the pivot of the arm, a pin carried by the lever and engaging the inner face of the arm for throwing the same outwardly to move the scotch block from the rail, and a pivoted lever carried by the base and adapted to support the scotch block and to swing the same upwardly over the rail by a downward movement of the outer end thereof.
