JAMES A. THOMASON, OF ATLANTA, GEORGIA.

RAILROAD BUMPING-POST.

To all whom it may concern:

Be it known that I, JAMEs A. THoMAsoN, a citizen of the United States, residing at Atlanta, in the county of Fulton and State of Georgia, have invented new and useful Improvements in Railroad Bumping-Posts, of which the following is a specification.

This invention relates to bumping posts, and the object of the invention is to provide a simple, inexpensive, strong and endurable device of this character which is so constructed and arranged as to provide an-eifective stop for cars without danger of injury to the draw heads or coupling devices thereof.

Another object of the invention is to provide a bumping post, having rail tracks adjacent the posts upturned to form a semielliptical continuation of the track, suitably braced and adapted to serve as an additional retarding means for the wheels of the car.

A still further object of the invention is to supply an additional means to provide a preventive from and without injury to, the attachments connecting the boxes or bodies of cars with the trucks or running gear by means of the springs at the bumping posts catching the rebound so as to prevent injury in operating cars and engines and especially in preventing the box or body of the cars from being detached from the trucks or run ning gear.

With these and other objects in view the invention resides in the novel construction and arrangement of parts, hereinafter fully described and claimed.

In the drawings, Figure 1 is a side eleva tion of a bumping postconstructed in accordance with my invention. Fig. 2 is a top plan view of the same. Fig. 3 is a trans verse sectional view upon the line 33 of Fig. 2. Fig. 4 is a longitudinal sectional view .upon the line 44 of Fig. 2. Fig. 5 is a similar view upon the line 55 of Fig. 1.

In the drawings the numerals 1 and 2 designate a pair of railway rails secured upon the ties 2 by the usual spikes. The rails 1 and 2 are provided with semi-elliptical bands 3, extending upwardly in parallel relation with each other and thence continued downward and rearward as at 4, terminating in the rail extensions 5. The under faces of the base flanges of the rails 1 and 2 are provided with a suitable metallic plate 6, adapted to be positioned upon the ties 2, and to extend a suitable distance upon the rails so as to provide a brace for the rails, at the space Specification of Letters Patent.

provided by the semi-elliptical up turned portion 3 and the continuation 4 of the rails. In order to more securely steady the rails and plate 6, sills 7 are positioned beneath the ties 2 for a suitable distance beyond the space caused by the up turned portions of the rails.

The upper portion of the extension 3 is provided with a suitable bracing bar 8, having its opposite extremity secured to the extension 5 of the rails directly above the plate 6 and sill 7. The bar 8 is also providedv with a bracing strip 9, secured to the bar and the continuation 4 of the rails. The extremities of the up turned portions 3 of the rails are provided with a transverse connecting element 10, by which the rail members have their up turned portions 3 secured in suitable spaced relation with each other. The brace bars 8 are also provided with a transverse connecting element 11, which serves as an additional means of retaining the tracks in proper relation with each other as well as forming a substantial structure.

Positioned intermediate of the rails 1 and 2, and at a suitable distance from theup turned portions 3 thereof is a buffer post 12. The post 12 is disposed between two of the ties and has its lower ortion embedded in concrete 13, as clearly i lustrated in Fig. 4 of the drawings. The post 12 is provided with a suitable buffer plate 13, having a squared extension 14, extending through a suitable opening provided within the post 12. plates 15and 16 are provided upon the post adjacent the inner face of the buffer plate and the free end of the extension 14. Interposed between plate 16 and an annular flange 17, provided upon the inner face of the buffer plate 13, is a series of compression springs 18, normally adapted to force the plate 13 away from the post 12. These springs 18 may be of any desired formation, but as illustrated. in Fig. 5 of the drawings, I have preferably employed a series of springs, each. of which being smaller in circumference than the other and having the larger springs adapted to overlie the smaller springs. The extension 14 of the plate 13 is provided with a suitable cotter pin 19, and between a washer 20 and a suitable plate 21, is interposed a helical spring 22, adapted to serve as a retarding element when the plate 13 is forced outwardly under the expansion of the springs 18.

The rear face of the post 12 is provided with a plurality of inclined braces 23 having their free ends provided with offset or feet 24,

Wear

tie 26, while the lower portion of the bolt is.

provided with a nut 27, adapted to serve as an anchor for the bolt within the concrete 28.

The plate 21 1s provided'with angular extensions 29, adapted to engage the sides of the post 12 opposite the bulfer 13, and to be provided with extensions alining with the plane of the rails 1 and 2, and to be secured to the rails forward of the semi-elliptical portions 3. The post 12, is also provided with a bracing strap 30, extending around the faces of the post opposite the buffer 13, and secured to the post by suitable bolts 31. The ends of the strap are continued away from the post at a suitable angle and are provided with offsets adapted to aline with the rails 1 and 2 and with the extension provided uponthe brace arms 29, and to be secured to the extensions and the rails 1 and 2.

From the above description it will be noted that I have provided a simple and effective buffer for cars, one in which the rails are provided with a semi-elliptical upwardly extending portion, suitably braced, and provided with plates engaging the ties and being supported by a sill at the point of opening caused by the elliptical extension, the buffer post of which being suitably embedded in concrete and having rearwardly extending angular braces secured to a tie like wise embedded in concrete and provided with suitable anchors whereby the tie is securely locked, the post being provided with a suit able buffer having a brace connected directly with the rails, at a point where the concussion from the contact of the buffer of the car occurs, and that the post is also braced at its point of insertion within the concrete by suitable braceslike wise secured to the rails.

While I have described the preferred em bodiment of my invention, as it now appears to me, it is to be understood that minor de tails may be resorted to without departing from the spirit or sacrificing any of the advantages of the device.

Having thus fully described the invention what is claimed as new is:

1. In a bumper for cars the'combination with the track rails having semi-elliptical up turned portions and a rearwardly extending portion, of a post provided with a spring pressed buffer and having braces extending rearwardly'and braces connected with the rails.

2. In a bumper for cars the combination with track rails having semi-elliptical up turned portions and rearwardly extending portions, braces between the up turned portion and the extended portion, and a post provided with a spring pressed buffer and having rearwardly extending braces and braces connected with the rails.

3. In a bumper for cars the combination with track rails having semi-elliptical up turned portions and rearwardly extending portions, braces between the up turned portions and the extending portions and tie bars between the up turned portions'of the rails and the braces for the rails, and a post having a spring pressed buffer.

4. In a bumper for cars the combination with track rails having semi-elliptical up turned portions and rearwardly extending portions, braces between the up turned portions and the extended portions of the rails,

a'bracing strip between the braces and the A buffer.

5. In a bumper for cars the combination with track rails having semi-elliptical up turned portions and rearwardly extending portions, braces between the up turned portions and the extended portions, ties between the up turned portions of the rails, ties between the braces of the rails, plates between the rails and the ties beneath the openings formed by the up turned portions and the continuations of the rails, sills below the ties and the plates, and a post having a spring buffer.

6. In a bumper for cars the combination with track rails having semi-elliptical up turned portions and rearwardly extending portions, of a post embedded in a solid foundation and being provided with a spring pressed buffer, angular braces extending rearwardly from said post, said braces being provided with feet having suitable openings adapted for the'reception of retaining elements, anchors upon the retaining elements adapted to be embedded in a solid foundation, a brace engaging the post at the rear of the buffer and being connected with the rails beyond the elliptical portions of the rails, and a brace engaging the lower portion of the post and connected with the rails beyond the elliptical portion of the rails.

In testimony whereof I affix my signature in presence of two witnesses.
