RAILROAD-BUFFER CONSTRUCTION.

Application filed June 1, l1926, Serial No. 113,915, and in Germany November 13, 1925.

rlhis invention relates to a railroad-buimodied construction of Figure 3 it is not ter oi the thrust triangle type which is simple in construction and efficient in operation and comprises the use oi' wooden brake members in connection ber of a thrust triangle.

The invention is illustrated on the accompanying drawing.

Figure l is a side elevation of one embodiment ot the improved butler construction, some parts being broken away, and Figure 2 is a partial sectional View ot one of the buffer thrust triangles. Figure 3 is a partial sectional view similar to Figure 2 of a modiiied construction.'

In Figures 1 and 2 a buffer carrying rail is designated by a. is a farther rail7 forming an element of the triangle base. The side elements ot the thrust triangles are indicated by c. cl designates a wooden brake beam or brake block connected to rail o by bolts e having coiled springs f put thereon which tend to yieldingly press the brake beam Z against the track rails head a. The illustrated arrangement of the one thrust triangle is also provided for the thrust triangle of the other rail, both triangles as usually being connected together by a buffer beam g.

The application of the buffer base as an clement of a slide construction results in a particularly simple construction whereas he connection of this metal piece with a wooden brake block ensures proper braking etiect by irictional engagement ot sliding parts and certain elastic qualities favorable 'for the transmission of thrust.

.lt is not essential for the invention that the rails a on which the buiier is mounted, are the rails on which the vehicle or train to be stopped by the buiier is running; the butter may be mounted on sepa-rate flanged beams in parallel relation to the track rails. it will be understood that these beams need not to be raiis and likewise it is not indispensable that the base element of the buffer consists ot a normal rail; any other suitably flanged beam may be used which by its flange is in engagement with the tia-nge ot a carrying beam.

in the butter construction of kFigures 1 and 2 it is particularly the strong frictional engagement between the wooden beam d and the butter carrying rail a whereon the etliciency ot the construction on sliding displacement o the buer depends. In the with the base mem! so much this function but a certain resiliency of the wood'whereon the eiiiciency of the construction depends, may it be in connection with a sliding arrangement of the buffer, may it be in connection with'a buffer ot' the stationary type. In' Figure 3 the ret erence letter L designates the side elements ot a. thrust triangle7 z' are claw members rigidly secured thereto and iirmly gripping the rail or metallic beam 7c on which the buiier is mounted. Z is a wooden beam firmly connected with the buffer and in tight contact with the upper surface of the beam 7c. Gn impact ot' a car or train on the buiter the exerted shock tends to tilt the butter so as to press down the buiier end remote from the impacting car. Under the eiiect of this tilting tendency the wooden beam Z at the said end of the buffer remote from the car is somewhat compressed and it has been found that such compression ot' an intermediate member ot a somewhat elastic and not absolutely rigid nature such as wood materially aids in the taking up of stress, so that with the insertion of such a wooden or the like beam the buer is adapted to take up much more violent shocks than without same.

What I claim is v 1. In a railroad butter Vconstruction a thrust triangle mount/ed on a flanged beam, said thrustA triangle having a base element comprising a flanged metallic beam engaging with its iiange the flange of the supporting beam, said metallic base element ot the thrust triangle connected with a non-metallic friction member contacting with the supporting beam, the triangle adapted to slide along the supporting beam under rictional engagement of said non-metallic member and the supporting beam..

2. In a railroad buffer construction a thrust triangle mounted on a rail, said thrust triangle having a base element comprising a i'langed beam engaging with its flange the head of the supporting rail, said flanged beam connected with a non-metallic member contacting with the head of the supporting rail, the triangle adapted to slide along the supporting rail under frictional engagement of said non-metallic member and the head of said supporting rail.

3. In a railroad buiier construction a thrust triangle mounted on a rail, said thrust triangle having a base element comprising a rail section engaging with its head portion the headvl of the supporting rail, said rail section of the triangle base being connected with a Wooden member rietionally engaging the lateral Surface' of the supporting rail' head opposite that side of the rail head which is in engagement with the triangle base rail, the triangle adapted to slide along the supporting rail.

4.111 a railroad buffer Construction a thrust triangle mounted on a rail, said thrust triangle having a base element comprising a rail section engaging with its head portion the' head on the supporting rail, said rail section of the triangle base being yieldingly connected with a Wooden member frictionally engaging the lateral surface of the supporting rail head opposite that side' of the rail head Which is in engagement With the triangle base rail, the triangle adapted to slide alongv the supporting' rail.

5. In a Irailroad buffer construction a thrust triangle mounted on a rail, Said thrust triangle having a base member comprising a Wooden beam positioned along the upper surface of the head of the supporting rail and metallic connectors maintaining the triangle in lifting preventing engagement With the supporting rail,

In testimony whereof, I aiiix my sig-na ture.
