Specification of Letters Patent.

' Patented Nov. 7, 1916.

Application fi led March 18, 1916. Serial No. 85,190.

To all whom it may concern Be it known that we, HARvnY E. Score: and ABNER L. Sco'rr, citizens of the United States, residing at Alleene, in the county of Little River and State of Arkansas, have invented new and useful Improvements in Railroad-Track Construction, of which the following is a specification.

This invention relates to improvements in railroad track construction.

The primary object of the invention is to provide means whereby the space between the opposed ends of the rails which is left to permit the expansion and contraction of the rails will be materially reduced or compensated for.

A further object of the invention is to provide blocks or short rail sections for disposition between the opposed ends of the rails and to connect the same with each other and with the rails, so that, when the rails contract the blocks or short rail sections will be caused to move a slight, but predetermined distance, away from. each other and away from the opposed ends of the rails, thereby decreasing the gap between the rails and preventing the rolling stock which passes over the rails being subjected to the shock and jars which now ocour in the track construction now in common use.

A still further object of the invention is to so arrange and connect the short rail sections which are disposed between the op posed ends of'the rails that rain or snow which may gain access between said sections upon freezing will-be enabled to expand without loosening the connections between the short rail sections and the opposed ends'of the rails.

A further object of the invention is to provide blocks or short rail sections for disposition between the opposed ends of the rails which may be supported by the angle.

plates connecting the rails in such a manner,

as to cause the tops of said blocks to lie flush with the-tops of the rails.

A still further object of the invention is to provide blocks or short rail sections for disposition between the opposed ends of the rails which are so constructed that members for connecting the blocks or short rail sections with each other and with the opposed ends of the rails will be covered by the angle plates connecting the rails.

With these and other objects in view the invention residesin the novel combination and arrangement of parts, which will be hereinafter described and particularly pointed out in the claims.

The preferred form of the invention has been illustrated in the accompanying drawing, although no restriction is necessarily made to the precise details of construction therein shown, as changes, alterations and modifications within the scope of the appended claims may be resorted to when so desired.

1 Like characters of reference denote corresponding parts throughout the several views in the drawing, in which:

.Figure 1 is a perspective view of the meeting ends of two railroad rails and showing the invention applied thereto. Fig. 2 is a side elevation of the meeting ends of two railroad rails with the angle plate removed therefrom and showing the blocks in spaced relation with, each other and with the ends of the rails. Fig. 3 is a horizontal longitudinal sectional view on the line 33 of Fig. 2. Fig. a is a vertical transverse sectional view on the line 4l of Fig. 1. Fig. 5 is a detail perspective view of one of the blocks or short rail sections.

Referring now to the drawing in detail. rail sections 1 and 2 are supported upon a base plate 3 with their opposed ends in spaced relation, said plate. being secured to ties 4 by means of spikes 5 received in notches 6 at the side edges of the base plate 3.

The rail sections 1 and 2 which are of the type now in common use have passing through the spaced openings 7 in the webs thereof bolts 8 which are also received in the elongated slots 10 in angle plates 11 associated with the rail sections.

Bracing plates 12 with the bolts 8 are arranged exteriorly of the angle plates 11 adjacent their ends, said bracing plates having formed therein openings 13 which receive the portions of the bolts 8 which project beyond the angle platesll. The plates 12 not only serve to brace the bolts 8 but are so arranged as to cover the elongated openings 10 in the angle plates and exclude foreign matter therefrom.

The usual nuts 14k are threadedly engaged with the threaded ends of the bolts 8 and coact with the heads 9 thereon in retaining the plates 12 in contact with the angle plates and'the angle plates in contact with the rail sections.

Through the above described arrangement of the angle plates, rail sections, and bolts, it will be seen with reference to the various figures in the drawing, that the rail sections may expand and contract within the angle plates which are held from movement by means of spikes 15 driven lnto the cross-tics 4: and received in the openings 16 in the lower edges of said plates which register with similar openings in the base plate 3.

Blocks 17, 18, and 19 which correspond with the shape of the rails and for this rea son have been termed short rail sections are disposed between the opposed ends of the rails and received between the angle plates 11 between which said blocks or short rail sections may be moved longitudinally within the space between the opposed ends of the rail sections.

Each short rail section comprises a head 20, web 21, and a base 22, with the base 22' of each block: or short rail section resting uponthe base plate 53 and the underside oi thehea'd of said section contacting with the" upper edge of the angleplate 11, so that said blocks or short rail sections are efiectually supported by the angle plates 11 to prevent vertical movement ofthe same when in contact with the wheels of rolling stock.

The webs 21 of each block or short rail section are of the same thickness as the web plates upon opposite sides of the rail sections.

A pin 25 extends laterally from the web of each block or short rail section at a point equi-distant from the head and base thereof, said pins contacting with the inner face 01 the angle plates to prevent casual displacement from the pins of links which will now be described. a

Links 26 and '27 for connecting the blocks or short rail sections with each other and with the rail sections are arranged upon opposite sides ofthe railsections and blocks within the fishing spaces 24.

' The links 27 are arranged in pairs upon opposite sides ofthe blocks or short rail sections, with each link in each pair of links ing a pin 25 on the block or short rail section 18 and provided near itsother end with an elongated slot 28 receiving a pin 25 on an adjacent block or short rail section.

The links 26 are arranged in pairs at the ends of the rail sections 1 and 2, with each link in each pair of links having near one end an opening 29 receiving a bolt 8 passing through the rail section and'angle plates 11, the other end of the link having an elongated slot 29 receiving a pin 25 on an ad'- jacent block or short rail section.

Through the above described arrangement or" the links 26 and 27, it will be seen that the blocks or short rail sections, are connected with each other and with the rail seecontraction of the, rail sections 1 and 2 which are free to move longitudinally of the angle plates 11, the ends of the slots in the' links 27 will be brought into contact w'iththejpins 25 on the blocks or short rail sect-ions 17 and.

19, thereupon the movement of the rail sections 1 and 2 longitudinally of the angle plates will cause the short railsections 17 and 19 to be moved with relation to the'section 18, so that, a-slight space is formed be-; tween the short rail section and the opposing ends of the rails.

.l Vhen the rail sections-1 pand they first contact withthe sections 17 and 19, and upon further expansion of said rail sections the blocks or short rail sections 17 and 19 will be moved by therails into contact with the shortrail section 18 thereby eliminating the space between the blocks or short rail sections and the opposing ends of the rails 1 and 2.

Having thus described the invention what is claimed as newisza V 1. The combination with two connected rails, of members arranged between the rail ends, links connected with said members and rails and actuated by the contracting of the rails" to move said members an equal distance away from-each'other and from the ends or the rails. i

2. Thecombination'withtwo rails having opposing ends,- of members arranged be tween the rail ends and alining' with the] and 2 again exheads of the rails, and meansconnected i with the rails and the members and ac'tuated by the contracting of the was for moving;

said members an equal distance away from each other and fromthe-en'ds of the" rails,

and angle plates connected with the rails and contacting with said members to support the same.

3. The combination with two rails having opposing ends in spaced relation, of a plurality of members interposed between the ends of the rails and provided with heads alining with the heads of the rails, angle plates connected with the rails and contacting with the heads on the said members and providing a guideway in which said members may slide, and means connected with said members and the ends of the rails for imparting a sliding movement thereto when said rails contract or expand.

4-. The combination with two rails having opposing ends in spaced relation, of a plurality of members interposed between the opposing ends of the rails, pins carried by said members, angle bars connected with the rails and having their inner faces contacting with the pins to hold said members in alinement and slotted links connected with said members and rails whereby said rails upon expanding or contracting may move independently of said members.

5. The combination with two rails having opposing ends in spaced relation, of a plurality of members interposed between the opposing ends of the rails, and each comprising a head, a base and a web connecting said base, pins extending laterally from the web on each member, slotted links connected with the members and rails adapted to communicate sliding movement to the members when the rails expand or contract, and grooved angle plates connecting the rails and contacting with the pins on the members and coacting with the webs on the rails and members to provide a housing for said links.

6. The combination with two rails having opposing ends in spaced relation, of members disposed between said ends, pins extending laterally from said members, links connected with said pins and rails with some of said links provided with slots receiving said pins whereby said members may move independently of each other upon expansion or contraction of the rails.

7. The combination of two rails having opposing ends in spaced relation, a plurality of alined members interposed between the ends of said rails, pins on said members, slotted links connected with said members whereby upon expansion and contraction of the rails the members may be moved in spaced relation, and bolts passing through the ends of the rails and connected with the links on the end members to enable the rails to contract or expand without communicating movement to the alined members.

In testimony whereof we afiix our signatures in presence of two witnesses.
