TRACK-TERMINAL.

Specificationof Letters Patent. Patented Mar. 23, 1920- Application filed October 27, 1919. Serial No. 333,591.

To all whom it may concern:

Be it known that I, SAMUEL ENGLISH, a citizen oi the United States, residing at Pittsburgh, in the county ofAllegheny and State of Pennsylvania, have invented new and useful Improvements in Track-Terminals, of which the following is a specification.

This invention relates to track terminals or abutments and has for its primary object the provision of means for stopping the travel of cars without injury to either the cars or the terminal.

Another object of the invention is the pro vision of a track terminal which is located in the path of a car and trictionally engageable with the track for the purpose of gradually stopping the progress of the car without the usual shock or jar.

Another object is the provision of a track terminal of the above character having a wear plate, which is removable, so that the said plate may be replaced, when desired.

A further object is the provision of a slidable track terminal having means for turning the same to normal position after being released by the car.

Other objects and advantages of the invention will appear as the following descrip tion is read in connection with the accompanying drawings.

In the drawings:

Figure l is a plan view of a fragmentary portion of a track, with the invention applied thereto.

Fig. 2 is a side elevation of the same.

Fig. 3 is an enlarged transverse sectional view on the line 3-3 of Fig. 1.

at is a longitudinal section on the line el-d of Fig. 1.

Fig. 5 is a transverse section through the track showing the opening in the road bed for housing the counter-balance weights.

Fig. 6 is a detail perspective view of the shoe.

Fig. 7 is a similar view of the wear plate.

Referring in detail to the drawings, like characters of reference denote corresponding parts throughout the several views.

in carrying out the invention, it is preferred to bend the ends of the rails slightly upward, so as to provide an inclined road bed, as shown at 10, although this in some cases may not be essential.

ltlounted upon each rail of the track, is a shoe 11; the latter comprising a top wall 12 and side walls 13 and it, the shoe being shaped substantially to conform to the shape of the rail head, as shown in Fig. 3. The receiving end of the top wall is slightly "tapered, as is also the extremity ol the wall 14, as indicated at 15. The wall 14L is disposed upon the inside of the rail, the taper 15 permitting the flange of the wheel to ride easily but will be held against unauthorized removal. The said shoe, however, may be re moved by sliding the same longitudinally over the end of the rail.

Located within the shoe, is a wear plate 17, the latter comprising a relatively thiclr metal bar, which is beveled at one end, as indicated at 18, so as to permit the car wheel to readily ride upon the top of the shoe. The opposite end of the bar 18 is provided with a curved extremity 19, which is located within a pocket 20, formed by the upwardly curved end 16 of the shoe. The wear plate is held in position within the shoe tl'irough the medium of a removable pin 21, which passes through registering elongated slots formed in both the shoe and wear plate, so that the plate may be easily replaced, the said pin serving to hold the plate against accidental removal, as will be hereinafter apparent. The pin 21 fits loosely within the slots, enabling the plate 17 to remain seated after wear. 7

In the use of the invention, a car riding upon the shoe will cause the latter to travel up the inclined portion 1O 01" the track distance governed by the speed and weight of the car, the rails being provided at their extremities with upturned portions 22 to limit the movement of the shoe.

After the shoes have reached their limit of movement, the car will then descend the incline, the wheels leaving the shoes, and. for the purpose of returning the shoes to their normal position, each shoe has connected thereto a chain or cable 23, which passes over a pulley 24:, located adjacent the inside of the rails. The opposite ends of the chains or cables 23 have secured thereto an opening 26 provided between the tracks.

This opening may be formed in any suitable manner, such as of concrete construct1on and may be provlded with a cover 27,

having openings 28 therein for the passage of the chains or cables.

For the purpose of conveniently connecting the chains or cables to the shoes, each shoeis provided along its lower edges with a tubular portion 29, formed by rolling the edge of theshoe, as indicated inFigs. 3 and 6, the rope or cable being passed through one of these tubular portions and provided upon its extremity with a suitable stop 30 which is of suflieient size to prevent its passage through the tubular portion 29.

The invention issusceptible of various changes in its form, proportions and minor details of construction and the right is 7 herein reserved to make such changes as properly fall within the scope of the apl pended claims.

Having described the invention, what is claimed is:

1. Theeombination with a car rail, of a friction shoe embodying a housing adapted toreceive the head of the rail, means whereby the shoe may be re1novably.and slidably secured to the rail, a wear plate carried by the casing for contact with the rail tread and means for returning the shoe to normal position.

2. The combination with a car rail, of a shoe comprising a casing reniovably secured to and slidable along the head of the rail, an upwardly extending extremity located at one end of the shoe to provide a pocket, a wear plate located within the shoe for contact with thehead of the rail and an offset extremity for said wear plate for insertion in said pocket.

3. The combination with a car raihoi a shoe comprising a casing removably secured to and slidable along the head of the rail, an upwardly extending extremity located at one end of the shoe to provide a pocket, a wear plate located within the shoe for contact with the head of the rail, an offset extremity for said wear plate for insertion in said pocket and a removable pin extending through openings in the wall of the pocket and the offset extremity of the wear plate.

In testimony whereof I afiix my signature.

SAMUEL ENGLISH.
