CHARLES @LEVEL ND. OHIO- BUFFER FOR CARS.

Application filed December 22, 1921. Serial No. 524,269.

.Cars, of which the following is a specifica- This invention relates to buffers for cars, and has for its main object to provide a buffer which is adapted to slide upon the rails of a track 1 01 reducing the jar in bringing .a car to a standstill.

Another object of the invention is :to proride a buflier .of simple and practical .construction, which will support the rear wheels of a car for utilizing the weight to increase the braking power .of .;the buifer.

A furtherobject .of the invention is to provide a buffer of said character, which will be drawn back to its original position by the car when the car is moved away .after being brought to a standstill.

With the above .and other objects in view, as will be readily understood, the invention will be hereinafter fully described as illustrated in the accompanying drawings, and the novel features {thereof will .be distinctly pointed out in the appended claims.

Similar characters of reference are used in the Several drawings to designate corresponding parts.

Figure *1 is a side elevation of a track ,with a .car thereon, and a buffer constructed in accordance with any invention in position .upon said track for bringing the car to a standstill,

Fig. 2 is a .plan view .of the buffer upon the track as illustrated in Fig. 1,

Fig. 3 is an end view of Fig. 2,

Fig. 1 is a side elevation of the buffer,

Fig. 5 is a similar view to Fig. 4, one side of the buffer being eliminated, and the pull-bar engaging the axle of a car for drawing the buffer back to its original position after the car has been brought to a standstill, and

Fig. 6 is a front view of Fig. 5.

Referring to the drawings, 1 represents rails fixed to cross ties 2, and 3 a car carried by axles 1, which are supported by wheels 5 for travelling upon said rails, all of ordinary construction. The buifer consists of a pair of

shoes

6 and 7, which are adapted to slide longitudinally upon the rails of the track and support longitudinally extending sidesS and9 connected by a transverse block 10. The

shoes

6 and 7 extend forwardly of the

sides

8 and 9 for accomn'iodating the wheels 5 of the car 3, and said sides extend beyond face 11 of the block 10 and their edges are curved inwardly at 12 to correspond with the peripheriesof said wheels. Depending

flanges

13 and 14 at the outer sides of the

shoes

6 and 7 are adapted to engage the outer sides of the rails of the track .to retain the buffer thereon. hen a car is :backed so that a pair of its wheels rest upon the forwardly extending portions of the

shoes

6 and 7 and said wheels engage the curved edges 12 of the

sides

8 and 9, the buffer is forced or pushed along the rails .of the track and the weight of the car also tends to increase .the friction between the shoes and the rails. thus bringing the ,car to a standstill and avoiding any sudden jarringof the car as is the case when striking a fixed or stationary buffer.

In order to return the buffer to its original position when {the car is drawn away after being brought to a standstill, a pull-bar 15 is pivoted at 16 between a pair of lugs 17 and 18 projecting from the face 11 of the transverse block 10, and its free end is provided with a suitable hook 19, which is adapted to engage the axle 4 of the car as the car is drawn away. For disengaging the hook 19 of the pull-bar 15 from the axle l of the year when the buifer is again at its original position, a guide member 20 is fixed to one of the cross ties -2 at such position asto be engaged by said pull-bar, and this muses the hook of the pull-bar to be lifted clear .of the car axle, thus releasing the car and leaving the buffer in its original position for the bringing of the next car to a standstill. The under edge of the pull-bar 15 is preferably swelled out at 21 to provide a cam for engaging the guide member 20. The buffer may be set with the pull-bar 15 resting upon the guide member 20, or it may be left at some other place along the track, in which case it is necessary that the free or hook end of the pull bar should not be below the car axle. For holding the pull-bar so that its hook end will be above the car axle, the pivoted end of the pull-bar is provided with a depending lip 22 for engaging the face 11 of the transversal block 10, and in order that the hook end of the pull-bar will slide over the car axle, its lower edge is beveled at 23.

. position upon a track or used on different tracks for bringing a car to a standstill. It will be understood that slight changes in the details of construction maybe made within the scope of the claims.

Having fully described my invention, what I claim is: b

1. In a buffer, the combination of means adapted to slide upon a track for bringing a moving bodyto a standstill, a pull-bar, the pull-bar having one end pivoted to said .means, and the other end of the pull-bar being adapted to be engaged by the body when the body is moving in'one direction to actuate said end of the pull-bar upwardly and to effect connection with the body when the body moves in the other direction, substantially as described.

2. In a buffer, the combination with a car having an axle, of means adapted to slide upon a track for bringing the car to a stand still, a pull-bar, the pull-bar having its rear end pivoted to said means, a hook at the forward end of the pull-bar adapted to engage the car axle, the hook having a bevelled edge adapted to be-engaged by the car axle when the car moves rearwardly to cause the hook to pass over the car axle,

' and the hook being adapted to be connected with the car axle when the car moves for wardly, substantially as described.

3. In a buffer, the combination of a block adapted to slide upon a track for bringing a car to a standstill, a pull-bar pivoted to the block, and the pull-bar being provided with means for effecting a connection with a car when the car is withdrawn from the block, substantially as described.

4. In a buffer, the combination of a block adapted to slide upon a track for bringing a car to a standstill, a pull-bar pivoted to the the car is movedoff said shoes,

-means for effecting a connection with a car when the car is withdrawn from the block, and a guide member for causing the d1scon- ,necting of the pull-bar from the car as it moves, substantially as described.

. 6. In a buffer, the combination of a block adapted to slide upon a track for bringing a car to a standstill, a pull-bar pivoted to the block, the pull-bar having a hook at its free end for effecting a connection with a car when the car is withdrawn from the block, and the pull-bar having means at its pivoted end for engaging said block to hold its free or hook end at a certain height, substantially as described.

7. In a buffer, the combination of shoes adapted to slide upon rails, sides supported by the shoes, a block connecting the sides, the shoes extending forwardly of said sides for accommodating the wheels of a car, the sides having curved edges forreceiving the Wheels of the car, and means for effecting the connection of the block to the car when substantially as described.

8. Ina bufi'er, the combination of shoes adapted to slide upon rails, sides supported by the shoes, a block connecting the sides, the shoes extending forwardly of said sides for accommodating the wheels of a car, the sides having curved edges for receiving the wheels of the car, a pull-bar pivoted to said block, and the pull-bar having a hook at its free end for effecting a connection with the CHARLES HIERL.
