Specification of Letters Patent.

Patented Aug. 2a, 1915.

Application filed. December 18, 1914. Serial No. 877,939.

To aZZ whom it may concern:

Be it known that I, LEWIS A. C RTIS, a citizen of the United States, residing at Hartford, in the county of Hartford and State of Connecticut, have invented new and useful Improvements in Railway-Ties, of which the following is a specification.

The present invention relates to improve ments in ties for railway rails.

In carrying out my invention it is my purpose to construct a tie having a frame of iron, and if desired, and in some instances found necessary, a plastic body within which the frame is embedded, the same embodying suflicient resiliency to compensate for the shock and jar incident to the weight of the rolling stock passing thereover, the same being yieldable under the strain or weight of the said rolling stock, so that injury to the rails or to the tie will be effectively overcome.

It is also my purpose to Construct a tie including a suitable body to arrange upon the same a rail support constructed from a single piece of suitable resilient material and comprising parallel upper and lower members and rounded connecting ends, and to also provide novel and effective means for securing the rail upon the rail support.

With the above and other objects in view, the improvement resides in the construction, combination and arrangement of parts set forth in the following specification and falling. within the scope of the appended claims.

In the drawings: Figure 1 is a transverse section through the tie showing a rail secured upon the supporting member thereof, Fig. 2 is a side elevation of the same, Fig. 3 is a perspective view of one of the rail seat supporting members, Fig. 41 is a similar view of one of the rail clamps, Fig. 5 is an end view of a tie constructed wholly of metal, and Fig. dis a longitudinal sectional view through the same approximately on the line 66 of Fig. 5.

Upon street railways or the like where only a single car passes over a tie at spaced intervals or wherein the weight of the car can be readily withstood by a plastic tie I have found it desirable to employ such class of ties, the same being illustrated in Figs. 1 and 2 of the drawings. In the said figures the numeral 1 designates a plastic body which is formed in a suitable mold, being sufliciently tamped to render the same, when dried, a substantially solid member. The body 1 is provided with angular sides 2 and if desired angular ends. The top 3 inclines downwardlyfrom its center in opposite directions toward the inclined sides 2, while the bottom of the tie is preferably straight. With this arrangement the inclined top and inclined sides will shed the moisture from the tie, and also the peculiar arrangement or shape of the tie permits of the same being firmly embedded to prevent either lateral or longitudinal movement when tamped within the road bed. Embedded within the body 1 and extending longitudinally thereof are spaced combined reinforcing and rail seat supporting members 4.-. These members have their opposite edges flanged, as indicated by the numerals 6 and 7 respectively, the web or connecting member for the flanges 6 and 7 being preferably fluted as indicated by the numerals 8. If desired, a connecting member may be arranged be tween the fluted webs 8 as indicated by the numeral 9, and likewise a connecting member 10 may be secured to the lower flanges 7 of the said members. It is to be understood that the employment of the members 9 and 10 is optional when the said members 4 are employed with a concrete body. Besting upon the upper flanges 6 of the members 5 and extending transversely through the body 2 is the lower straight member 11 of the rail support 12. The upper member 13 of the said support and upon which the rail 14. rests is parallel with the lower member 11 of said support or rest, while the opposite ends of the member 12 are curved to provide connecting sides 15 for the members 11 and 12. The portion 12, upon which the rail rests, is preferably of a less length than that of the member 11, and the said member 11 is secured to the flanges 6 by suitable bolts 16 which are embedded within the body 1 and which project through openings in the member 11 of the rail rest 12, while nuts 17 are arranged upon the projecting shanks of said bolts 16 to secure the member 12 to the body. The bolts may be arranged within suitable openings in the upper inclined top of the body 2, as illustrated in Figs. 1 and 2 of the drawings. The lower member 11 may be slotted or divided, one of the ends overlapping the tact with the opposite longitudinal edges of the base flanges of the rails to prevent a lateral movement of the said rails upon the second end and being secured together through the medium of a suitable rivet or the like, as shown in Fig. 1 of the drawings.

For securing the rail 1 1 upon the flat upper member 13 of the rail rest 12, I provide the said portion 12 with openings through which pass the shanks of bolts 19, the said shanks contacting with the opposite longitudinal edges of the rail 14. I also employ clamps 20', each of which being substantially U-shaped in side elevation, the lower flange 21 of each of said clamps being bifurcated to engage with the heads of the bolts 19. The upper flanges 22 of the clamps are provided with openings 23 through which extend the shanks of the bolts 19, while nuts 24 are arranged upon the projecting threaded shanks of the bolts and are forced into contact with the upper flange 22 of each of the members 20. By such an arrangement it will be noted that the bolts normally conrest or seat but also the bifurcated ends 21 of the said clamps eflectively hold the bolts against turning so that danger of the accidental removal of the bolts will thus be prevented.

In Figs. 5 and 6 of the drawings the device illustrated is substantially similar to that previously described, except that the plastic body 1 is dispensed with. The rail seat 25 is substantially similar to the rail seat 12, except that the same is preferably formed from a single casting or from a single strip of suitable resilient material, the

rest supports 26 each including angular flanges 27 and 28 which are formed upon the opposite edges of the web 29. The upper flanges 27 are secured to the lower member 30 of the rail seat 25 through the medium of removable elements, preferably in the nature of bolts 31' andnuts 32 therefor. The webs are provided with a plurality of connecting members preferably in the nature of rivets 33, the shanks of saidrivets between the said members 26 being surrounded by suitable sleeves 3 1, while the lower flanges 28 of the members 26 are connected by a plate 35, the said plate being secured to the flanges by rivets or other suitable securing members 86. This last described construction of ties is primarily adapted to be used upon railroads wherein the traflic is heavy and the weight of the rolling stock subjects the tie and rail seats to severe strain, and the railsare secured upon the seats preferably through the medium of clamps similar to those previously described, but, of course, other securing means may be employed without departing from the spirit or sacrificing any of the advantages of the invention.

per member for securing a rail thereto, and

supports for the seat secured to the lower member thereof.

3. In a tie for railway rails, a seat comprising a continuous member having round ends, means for securing a rail upon the seat, said means contacting with the opposite longitudinal edges of the rails, and sup.- ports for the seat.

1. In a tie for railway rails, a seat constructed of resilient metal and comprising upper and lower parallel members and rounded connecting ends for the said mem-, bers, means for securing'a rail uponthe upper member of. the seat, a support for the seat, said support including spaced longitudinally extending members having upper and lower flanges said upper flanges underlying and being connected to the lower member of the seat.

5. In a tie for railway fails, a metal seat comprising upper and lower spaced members, means for securing a railto .the upper member, supports for the seat, said supports including spaced longitudinal members having upper and lower flanges, means for securing the upper flanges to the lower member of the seat, spacing means for the members and bolts securing said means to the lower flanges of said members.

In testimony whereof I afiix my in presence of two witnesses.
