Application filed October 10, 1919. Serial No. 329,724.

To all whom 'it may concern.' Y,

Be it known that I, JAMES U. DUFFY, a citizenV of the United States, and a resident of Cleveland, county of Cuyahoga, and State of Ghio, have invented a new and useful Improvement in Car-Stops, of which the following is a specification, the principle of the invention being herein explained and the best` mode `in which I have contemplated applying that principle, so as to distinguish it from other inventions. f

The present invention relates to a stop for cars which may be secured along a section oftraclr to act as a stop or bumper of the type shown in U. S. Letters Patent No. 1,276,023, dated August 20, 1918, granted to Edward l/V. Breyley and myself. A shoe or skid is provided for receiving the car wheel which is then adapted to slide along with the shoe until it reaches a permanent stop fastened to the rail, the sliding action of the shoe being adapted to retard the movement of the car, so that it will be nearly stopped when the permanent stop block is reached. The device is so arranged that the Shoewill be returned to itsforward position as the carV is moved out of the device, and thereV are also means employed for releasing the car wheel from the shoe when the shoe reaches its forward position. To the accomplishment of the foregoing and related ends, said invention, then, consists of the means hereinafter fully described and particularly pointed out in the claims.

The annexed drawing and the following description set forth in detail certain meehanism embodying the invention, such disclosed means constituting, however, but one of various mechanical forms in which the principleof the invention may be used.

In said annexed drawing Figure 1 is a side elevation of my stop showing shoe in its forward position adapted to receive the car wheel; Fig. 2 is aside elevation showing the stop with a car wheel in place in an intermediate position along the rail; Fig. 3 is a side elevation showing the shoe in its nal position against the permanent stop; Fig. 4 is a section through the rail and channel iron on the line 4-4, Fig. 1; Fig. 5 is a section on the line 5 5, Fig. 2; Fig. 6 is a section on the line 6-6, Fig. 3; and Fig. 7 is a view similar to Fig. 2 showing a modied form of stop.

The present device is adapted, to be mounted upon a rail 1, it being understood that the devices are generally used in pairs, although only one device and rail are illustrated in the drawings. The mechanism consists of a permanent stop block 2 composed of two sections 3 having enlarged lower portions 4 adapted to t below the ball of the rail, and secured thereto by means of'bolts 5 which pass throughthe sections and the rail. 14s shown these sections extend up* wardly beyond the ball of the rail and have their forward faces 6 inclined at an angle to the vertical.

Upon the rail in front of the permanent stop is mounted a channel iron 7 having an upturnedlug 8 at its rear end and a raised portion 9 'at its forward end which inclines toward the rail surface.

Upon the channel iron is mounted a slidable skid or shoe 10 which has inclined forward portion 11 4up which the car wheel is adapted to run, and is then provided with a curved portion 15 adapted to receive the car wheel therein. This shoe or skid has a number of depending legs which fit over the channel iron and under the ball of the rail to hold the skid in place thereon. The rear leg l2 has its rear face inclined at the same angle as the forward face of the permanent stop with which it is adapted to engage. The forward leg 18 on the skid is inclined in the opposite direction and is adapted to engage with a small permanent stop 14 mounted on the rail'at the point ahead of the rail stop at which the device is to be nominally set. The intermediate forward stop consists of two sections having heavy base portions 16 adapted to tit under the ball of the rail and provided with inclined side portions 17 which reach upwardly along the sides of the rail to approximately `the top of the same, these sections being spaced from the rail suiiiciently to allow the flange of the wheel to pass be tween the sections lof the stop.

ln Fig. 7 a modified form of shoe is shown, in which the shoe 2O has an inclined forward portion 21 having a curved rear side 23 and a curved rear portion 24, the shoe being large enough to receive Y both wheels 25 and 26 of a car truck and hold them between the portions 23 and 24. In this form the channel 27 is of sufficient length to receive the forward truck and wheels 28 of the 'car so that the entire car is removed from the rail itself and rides on the shoe and channel.` The operation of this ward leg of the shoe in contact with the forward rail stop. W hen a car wheel or truck is run into the shoe the momentum ofthe car is first adapted to slide the shoe backward along the channel section until the rear end of the shoe engages the upturned v lug 8 upon the channel. iron, at which time the device will be in the position .shown in Fig. 2. The shoe and channel iron then slide together rearwardly until the shoe is in the position shown in Fig. 3, at which time the rear legs l2 on the shoe contact withk the permanent stop block on the rail to stop the car. It will be seen that the forward wheel of the truck or the forward truck rides upon the channel iron and, adds its weight upon the same to increase the friction between, the channel iron and the rail,

thus aiding in slowing down the speed of the car.

When the car :is moved away from the permanent stop the shoe is pulled alongv upon the channel sectionuntil the forwardfwheel of the truck or the forward truck rides o on the section and the point of the shoe engages the vraised forward end of the channel iron. The Vshoe and channel iron will then be moved forwardly together'until the shoe contacts with the forward stop block which preventsV the shoe from further forward movement and allows the car wheel or truck to be withdrawn from the shoe. y

lt is understood that the channel iron, as shown in Figs. l to 3 will be long enough to receive `at least the full truck of a car whether the truck has the yusual two wheels to the side or three wheels as in the usual Pullman cars, while inthe form shown in Fig. 7 the channel will be long .enough to receive the entire car.` The distance between the forward and rear stop blocks will be Vsuch as to normally bring the car to a full stop before the rear block is reached, the block being adapted to stop the car in case it is moving faster than normally or in case the friction is not sufiicient to stop it prior to this point. Y

The present device is comparatively light in weight and yet is strong enough to with. standthehard usage which it necessarily receives. rlhe blocks are fastened under the ball of the rail 'and have inclined faces which taire up the shock from the shoe. The tendency is to wedge the blocks against the lThe stop` is automatically returne ball of the rail, thus relieving the bolts from the shearing action of a straight blow. The parts of course may be made relatively light as the car is not to be stopped at once, but is gradually slowed down by the friction between the shoe, the channel iron and the rail, before the shoe contacts the sto block. to its normal receiving position and needs no attention while in use, as it isonly necessary to install it by slipping it upon the rail where it is to be used. The stop blocks may be readily attached by merely drilling holes in the rail. Thus a very compact inexpensive bumper or stop is obtained.

Other modes of applying the principle of my inventionmay be employed instead of. the one explained, change being made as regards the mechanism herein disclosed, providedv the means stated by any of the following claims or the equivalent of such stated means be employed.

l therefore particularly point out and distinctly claim as my invention l. In a car stop, the combination .of two' stop blocks attachedl to the rail, a channel iron slidably mounted on ysaid rail between said blocks, a shoe slidably, mounted on said channel iron and adapted to receive a car wheel, said shoe being adapted to slide in either direction with the carV wheel and engaging with said stop blocks to limit its movement.
