METALLIC SLEEPER OR TIE.

SPECIFIGATIdN forming part of Letters Patent No. 706,587, dated August 12, 1902. Application filed Decemher 16,1901. Serial No. 86.107. (No model.)

T0 at whom, it may concern/.-

Be it known that I, J OHN ISRAEL NEWBURG, a citizen of the United States, residing at Vicksburg, in the county of Warren and State of Mississippifhave invented new and useful Improvements in Metallic Sleepers or Ties, of which the following is a specification.

My invention relates to improvements in metallic sleepers orties and-means for fastening rails thereto; and it has for its objects, first, to provide a sleeper'or tie of such construction that it is stifl" and strong even when made of light sheetmetal second, to provide simple and inexpensive rail-fastenings for use in conjunction with straight and curved rails, respectively, said fastenings' being susceptible of quickand easy application and adapted to efiect strong and safe connections of the rails to the sleepers or ties, and, third, to provide a rail-fastening which, in addition to the advantages stated, is calculated to brace the head of a rail and reinforce the same against laterally-outward pressure.

The invention will be fully understood from the following description and claims when taken in conj unction with the annexed drawings, in which A Figure 1 is a perspective view illustrating a sleeper or tie constructed in accordance with my invention and portions of straight rails secured thereon by myimproved fastenings; Fig. 2, an enlarged detail section illustrative of the relative arrangement of the sleeper or tie, a rail, and the parts of one of the rail-fastenings; Fig. 3, a detail perspective View of the chair-bolt of the rail-fastening; Fig. 4, a perspective view of thesleeper or tie alone; Fig. 5, a view similar to Fig.3, illustrating a modified means for fastening rails to the sleeper or tie at curves, where the gage of the track is ordinarily increased; and Fig. 6 a detail perspective showing an anticreeping-plate.

Referring by letter to the said drawings, and more particularly to Figs. 1 to 4 thereof, A is my improved sleeper or tie, B B are rails of the usual construction, and C, D, and E are the chair-bolt, the rail holder and brace, and the nut, respectively, of the improved rail-fastening. The sleeper or tie is formed of a single piece of sheet metal of proper shape and size and is peculiar in that it comprises a longitudinal central portion a of in- "verted-U shape in cross-section, which exnels d and permit of the ready placing of bal last therein. The longitudinal central portion a lends rigidityand strength to the sleeper even when the same is formed of light .7

sheet, metal and also serves to support the meeting edgesof the top walls 6 e, which in turn are designed to support the rails, as shown in Fig. 1. Said portion a is provided in its top and at the inner ends of the walls 6 with an elongated aperture fiand itis also provided in its top portion, below-the walls e, with an elongated aperture. g, arranged coincident with a similar vapertureh, formed by notches in the meeting edgesofsaid walls.

The chairbolt 0 of the rail-fastening (shown in Fig. 2 and at the left of Fig. 1) is disposed longitudinally in the sleeper portion (1, immediately below the top thereof, and is provided at its inner end with a hook-shaped head 7;, which extends upwardly through and abuts against the'outer end wall of the 'aperturefand engages and holds one edge of the base of the rail B. At its outer end said chair-bolt is provided with an angular armj, which extends upwardly through the coincident apertures g h of the sleeper and has its upper edge beveled in conformity with the upper side of the base of the rail, as indicated by k, and also has a, reduced and threaded portion Z. The beveled upper edge of the arm j and the upper side of the base of-the rail-form a rest for the correspondingly-beveled basem of the rail-holder and brace D, which base has an aperture receiving the threaded r portion of the bolt and is secured thereon by a nut E. Said base is also provided with an aperture 71 to receive a pin F, the lower end ofwhich is beveled or wedge-shaped, as best shown in Fig. 2, so as to enable it to enter between and be securely held by the meeting edges of the sleeper-walls e. The pin F, secured in the manner described at the outer side of the nut E, obviously constitutes a nut-lock which is at once very simple and It will be appreciated from the foregoing that when the parts of my improvements are assembled in the positions shown in Fig. 2 a strong and durable connection of the rail to the sleeper is effected and one which will not interfere with free expansion and contraction of the rail; also that the combined railholder and brace D, the upper end of which is disposed below and in engagement with the outer side of the head of the rail, is calculated to reinforce the same and enable it to withstand the great lateral pressure imposed on it bythe flangesofcar-wheels. Itwillbefurther appreciated that when the head of the rail B is subjected tov laterally-outward pressure the head 'i of the chair-bolt, abutting against the outer end wall of the aperture f and also against the inner ends of the sleeper-walls (2, will strongly hold the rail against outward movement. Inward lateral movement of the rail will obviously be prevented by the armj of the chair-bolt abutting against the inner end'walls of the apertures g h of the sleeper.

The rail-fastening, arranged as described with reference to the sleeper or tie, is designed for use when a rail rests at an intermediate point of its length on the sleeper or 7 tie, as shown at the left of Fig. 1, and in order to adapt the sleeper or tie for connection through the medium of my improved fastenings with the meeting ends of two rails arranged thereon, as shown at the right of Fig. 1, I provide the sleeper-walls a with openings f, disposed at opposite sides of the longitudinal central portion a. ,Said aper tures-f are designedto receive the armsj of chair-bolt O, which have their heads 2' arranged in engagement with the inner ends of thewalls e and the inner edges of the railbases and are provided with the same appurtenances as the chair bolt 0. (Shown in Fig. 2.)

When desirable, the sleeper or tie in lieu of having the walls 6 at one end and walls 6' at' its other end may have either walls e or walls e at both of its ends, or if it is desired to adapt the sleeper or tie for use either beneath an intermediate point'of a rail or beneath the meeting ends of two rails it may be provided with walls e at its opposite ends, and said wallsin addition to apertures h, arranged coincident with apertures g in the portion a,

.may have apertures f without departing 'to 4 are designed more particularly for fastening'straight rails to the sleeper or tie, while the means shown in Fig. 5 is designed to fasten a rail to a similar sleeper or tie A at a narily slightly increased. The chair-bolt-G of the latter means is similar to that shown in Fig. 2, with the exceptions that its hookshaped head t" is stepped- 6. 6., provided with two abutments 2' i to engage the inner ends of the sleeper-walls e and outer end wall of the openingfand the inner edge of the railbase, respectively-and the inner side of its arm j is stepped or provided with two abutmentsj j to engage the outer ends of the sleeper portions 0. e and the outer edge of the rail-base, respectively. By virtue of the abutments' which engage the opposite edges of the rail-base being disposed in planes farther outward than the planes of the abutments which engage the sleeper or tie it will be readily observed that the curved rail B will be held nearer the end of the sleeper or tie than the rail B in Fig. 2, and the gage of the track at the curve will be increased, as is desirable, and this without entailing alteration of the sleeper or tie A. The rail-holder D (shown in Fig. '5) simply rests over the outer portion of the rail-base. It might, however, be extended up to the head of the rail in the same manner and for the same purpose as the com-. bined holder and brace D, if desired, without departing from the scope of my invent-ion.

With a view of holding the meeting ends of the rails on the sleeper or tie and prevent- IOO or tie and arranged to engage the same, and

hence it is enabled to securely hold the joint e., the meeting endsof the rails together and against movement off the sleeper or tie and the rails against creeping or casual endwise movement. v

I have entered into a detailed description of the construction and relative arrangement of parts embraced in the present and 'preferred embodiment of my invention in order to impart a full, clear, and exact understanding of the same. I do not desire, however, to be understood as confining myself to such specific construction and arrangement of parts, as such changes or modifications may be made in practice as fairly fall within the scope of my claims. f
