To all whom it-may concern Be it known that I, STEPHEN, D. MYERS,

a citizen of the United States,-residing atj Carrollton, in the county of Dallas and State of Texas, have invented certain new and useful Improvementsin Rail-Joint Shock-Absorbers, of 'wliich the following is a specification.

invention'relates to a-new'and useful rail joint shock absorber. a

When a train is passing over a track, the rails of which are connected by the ordinary form of joint, each wheel of the train will slightly depress one of the abutting rail ends of the joint before passing to the other rail end, thus communicating a frequently recurring shock or vibration to the crossties adjacent to the joint which will tend to eventually loosen the roadbed at this point.

It is the object of my invention to provide a means for resiliently supporting two abutting rail ends so as to eliminate what is commonlf called a low joint and the vibratory effect above described.

Finally the object of my invention is to provide a device of the character described that will be strong, durable, simple and efficient and comparatively easy to construct and also one that will not be likely to get out of order.

With these and various other objects in view, my invention has relation to certain novel features of the construction and use, an example of which is described in the following specification, and illustrated in the accompanying drawing, wherein:

Figure 1 is a view in side elevation showing my novel shock absorber correlated with a rail joint. Fig. 2 is a view of the same upon a smaller scale. Fig. 3 is a transverse sectional view of the same taken upon the line XX of Fig. 1.

Referring now more particularly to the drawing, wherein like reference characters designate similar parts in all the figures, the numerals 1 and 2 respectively denote two abutting rail extremities which are supported by cross-ties 3. A pair of ordinary fish-plates 4 are bolted against the two sides of the rail webs at the joint. Beneath the joint, a metal plate comprising parts 5, 6 and 7 is bridged between two ties 3f respectively extending beneath the abutt ng ra l ends. The portions 5 of said plate 11erespectively upon the ties 3 and are spaced slightly beneath the rail ends. The spikes I Specification of Letters l atent.

Application filed November 14, 1913. Ser-ialNo. 800,996.

7? which engage'the rails hand 2 with the ties '3 pass'through the end portions of the members 5, and are not driven sufiiciently deep. in the tiesfto' draw said rail ends down upon said members'5. The members 6 are vertically' disposed and respectively contiguous to the opposite lateral faces of the ties 3 The member 7 is a horlzontal connection between the lower ends of the members 6 flush with the under faces of the ties and contiguous to the roadbed. In the rectangular aperture formed between the parts 6 and 7 and the rail ends, there is vertically mounted a coiled spring 8 abutting at its lower end upon the member 7 and at its upper end against a plate 9 contiguous to the bases of the abutting rail ends. In the top face of the plate 9 there is counter-sunk the head of a bolt 10 cen trally disposed within the spring 8 and passing through the member 7. Upon the lower end of said bolt is screw-threaded a nut 11 which may be tightenedagainst the member 7 to produce a compression in the spring 8. It is thus seen that the abutting rail ends rest at their juncture upon the plate 9 which is in turn supported by the coiled spring 8.

The strength of the spring 8 and the amount of compression to which it is sub jected will be such that the weight coming upon the joint during the passage of a train over the same will be largely sustained by said spring 8. In case however the joint is obliged, during the passage of a train, to sustain an extraordinary weight, the spring 8 will yield downwardly sufficient to permit the abutting rail ends to be supported by the ties 3*. By thus resiliently supporting the abutting rails of a joint, the spring 8 constituting the resilient support is made to absorb the greater part of the vibration which is communicated to the joint during the passage of the train. The deleterious effect of such vibration upon the roadbed at the rail joint is thus eliminated.

The invention is presented as including all such modifications and changes as properly come within the scope of the following claims:

What I claim is:

1. In a device of the character described; the combination of two abutting rail ex ttemities, of a plate disposed beneath said rail extremities bridging the two ties nearest adjacent to the joint, the central portion of said plate 'being depressed betvreen said ties, a coiled spring abutting at its lower end against the depressed ponti(m'o"li'- said" plate and supporting the abuttingrail ends at its upper extremity, and means for ad just-ing the compression of said spring.

'2. In a device ofthe character described; the combination With two abutting rail ex. treniities of a plate disposed beneath said abutting upon the depressed central portion of said plate and supporting the tWo rail ends at its top, a plate interposed between the rail ends and the top of said spring, a *boltpa'ssing cen tralIy through the spring having its head counter-sunk in the top of said plate and having its loWer end projecting through the central portion of said plate and a nut screw-threaded upon said bolt adapted to be tightened against the central portion of said plate.

In testimony-whereof I. have signed my name to this specification in the presence of two subscribing witnesses.
