WILLIAM M. PERKINS, OF NORTH lMANCI-IESILER, INDIANA.

`SAFETY CEMENT RAILROAD-TIE.

Specification of Letters Patent.

Patented oct. 12, 1915.

Application led February 8, 1915. VSerial No. 6,869.

T 0 all whom it may concern Be it known that I, WILLIAM M. PERKINS, a citizen of the United States, residing ,at North Manchester, in thecounty of Wabash and State of Indiana, have invented certain new and useful Improvements in Safety Cement Railroad-Ties; and I do hereby declare the following to be a full, clear, andy load has been lifted.

Another object of this invention is to provide an arrangement which is flexible in its transverse direction but rigidly keyed against longitudinal strain.

Another object of this invention is to provide an arrangement which is firmly keyed to its bed.

Another object of this invention is to provide a composite tie provided with longitudinal reinforcing elements, said elements adapted to lock the rail to the tie.`

Other objects and advantages of this invention will be hereinafter more clearly set forth in the specification and pointed out in the claims.

Similar characters of reference refer to similar parts throughout the specifications and claims, in which,

Figure 1 isa top plan view of this device in assembled formation. Fig. 2, is a sectional elevation of the same, and, Fig. 3 is a sectional elevation of a portion of the tie Ishowing a modified form of means for clamping the rail to the tie.

In the drawings, the tie is composed of like members 1 and 2 preferably formed of concrete, each fof said members having a longitudinal recess 3 in the top portion thereof and a longitudinal recess in the lower portion thereof in which are mounted metallic bands or plates f1 and 5, said plates being integral their full length of the upper portion of the tie members and being seated in the groove 3 and extending beyond the inner ends 6 and 7 of the tie members and loopedback and seated in the longitudinal recesses in the under portion of the tie members. A plurality of vertically'positioned apertures 8 are .formed in each of the tie members through each of which is mounted a sultable sleeve 9, the metallic bands 4 and 5 having apertures adapted to register with -the apertures through the tie members.

Locking means l0 are mounted through these apertures, a portion of which are adapted to clamp a rail 11 of ordinary construction and the resilient bed pla-te 12 thereof to thetie to prevent lateral movement of said rails, said fastening means 10 having threaded ends 13 seating the locking nuts 14: for this purpose. Between the looped ends of each of the bands 4 and 5 andthe ends 6 and 7 of eachl of the tie members are mounted metallic structures 15 and `16 as shown in Fig. 2, Said structures and bands LLand 5 being preferably curved on their lower faces so that the major portion of the tie will be directed on the centers of 'each section. A vertically disposed aperture 17 is formed in each of these metallic members through which is mounted a locking bolt 10 held in position by the nut 14. A pair of oppositely disposed link members 18 and 19 are placed upon the sides ofv these metallic members and locked into posiing said link members in true parallel alinement with one of said tie members, the other member being allowed to play. It is to be further noted that the heads 22 of the bolts Y Asame tie constructions are used as illustrated above, the members 1 and 2 having the bands 4: and 5 therearound, the raily 11 and the bed plate .12, but in this instance the resilient ,base plate 12 is wider than the base flanges .of the rail 11, said base ianges and said base plate having registering apertures there.

through. Anchoring plates 23 and 24 are' oppos1tely disposed above the base flanges of the rail, the ends of which abut against the web of said rail, said plates extending to a neighboring locking bolt 10, said anchoring plates 23 and 24 having suitable apertures therethrough to engage the locking bolts 10 which are mounted through the said registering apertures, so that when the nuts 14 are threaded home, said anchoring plates 23 and 24 will securely bind the rai-l in position and prevent lateral displacement of the rail, the strain of said displacement being taken up by the neighboring locking bolts 10. Suitable angular washers 25 are 4placed between the flanged ends of the anchoring plates 23 and 24 and the nut 14 to prevent distortion of the locking bolts 10. By this arrangement when the load of passing cars is delivered to the ties, each portion thereof will properly givefthereby allowing of a r,e silient action of the rail l1, yet preventing lateral displacement of said rails,\said ties returning to their normal position after the load is released from off said ties, and likewise by means of the bands 4 and 5 and the locking bolts 10, the strain of this displacement is distributed to all points of said tie thereby insuring a strong and durable arrangement.

Having now described my invention what I claim as new and desire to secure by Letters Patent, is:

1. A composite railroad tie, comprising oppositely disposed members, metallic loop members reinforcing said oppositely disposed members, a metallic structure mounted in the looped portion of each of said metallic means, and pivoted connecting means, connecting said oppositely disposed members, and pivoted through said metallic structures to allow of resilient play of said members.

2. A composite railroad tie composed ofQ oppositely disposed concrete members having transverse vertically disposed apertures therein, sleeves mounted in said apertures, a looped metallic band above and below each of said concrete members, said bands having apertures registering with the apertures in said concrete members, reinforcing fastening meansv passed through said sleeves and locking. said metallic bands and linking means pivoted in the loop portion of said bands to allow of resilient play of each of said concrete members.

3. A composite tie comprising oppositely disposed concrete members having longitudinal recesses in the top and bottom portions, a metallic looped band, seated in' said recesses the loop portions thereof extending beyond the inner ends of said concrete members, metallic structures mounted in said looped portions, pivoted connecting means mounted throughr said metallic structures and connecting said concrete members, transverse locking 'reinforcing elements mounted through said concrete members and said metallic bands to reinforce and lock the same in position, a rail plate, a rail mounted upon said rail plate, and means locking said rail to a portion of said transverse locking means. 4. A composite tie comprising oppositely disposed members, loop reinforcing members, metallic members in said loop members, pivoted linking means mounted on said metallic members and abutting said loop portions, a rail plate mounted upon each of said oppositely disposed members, a rail mounted upon saidrail plates, and bolt means passing through said loop members and said oppositely disposed members, a portion of which operate to fasten said rails, the lower ends of said reinforcing means operating to anchor said tie to its bed to prevent displace ment therefrom.

ln testimony whereof l have signed my name to this specification in the presence of two subscribing witnesses.
