OTTO J. BOSTROM, EDWARD E. WALTMAN, AND RUDOLPH F. ZINGSI-IEIM, OF RAWLINS, WYOMING.

METALLIC RAILWAY CBOSSTIE AND RAIL-FASTENING.

Original application filed December 1, 1916, Serial No. 134,322.

1917, Serial No. 159,203. Renewed T 0 all whom it may concern:

Be it known that we, OTTO J. BosrnoM, EDWARD E. WVALTMAN, and RUDOLPH F. ZINGsI-IEIM, citizens of the United States, re siding at Rawlins, in the county of Carbon and State of lVyoming, have invented certain new and useful Improvements in Metallic Railway Crossties and Rail-Fastenings, of which the following is a specification.

This invention relates to new and useful improvements in metallic railway cross ties and is a division of our application for metallic railway cross ties and rail fastenings, tiled December 1, 1916, Ser. No. 134,322. r

The object of our invention is to provide an improved form of cross tie having a free movement or cushioning effect under each rail.

lVith the foregoing and other objects in view that will appear as the nature of the invention is better understood, the same consists in the novel features of construction, combination and arrangement of parts illustrated in the drawings and more particularly pointed out in the appended claims.

In the accompanying drawings Figure 1 is a side elevation of a metallic railway cross tie embodying our improvements, the rail fastening means and the' rails being also shown.

Fig. 2 is a plan view of Fig. 1.

Fig. 3 is a detail fragmentary sectional view of a portion of one end of the tie and the adjacent rail fastening means with the parts shown on an enlarged scale.

Fig. 4 is a detail sectional view taken through one of the keepers, its adjusting screw and associated parts. Fig. 5 is a bottom plan view of one of the rail fastening plates.

Fig. 6 is a plan view of one end of the cross tie.

Fig. 7 is a transverse section taken on line 77 of Fig. 6, looking in the direction indicated by the arrows.

Fig. 8 is a similar view, looking in the opposite direction as indicated by the arrows.

Fig. 9 is a detail fragmentary view of the central portion of the tie and the connecting rod used in connection therewith and Fig.

Specification of Letters Patent.

Divided and this application filed April 2, July 26, 1920. Serial No. 399,177.

10 is a detail perspective view of the connecting rod.

Referring to the drawings for a more particular description of the invention, 1 indicates the metallic cross tie, 2 the rails, 3 the rail fastening plates and A a connecting rod employed at the center of the tie, the purpose of which will be presently disclosed. The metallic cross tie comprises the flat approximately rectangular oblong base portions t which are formed at opposite ends thereof and are connected by the relatively narrow web or strip 5 at the center of the tie. The tie is also provided at each end with a flat top portion 6 which portions are supported upon and above said base portions 4 by the vertical legs 7 and the central longitudinal webs or ribs 8 which are cut away for the greater part of their width at the center of the tie, as at 9, and connected together by the movable connecting rod A above mentioned, the outer bifurcated ends 12 of the two sections a and Z) of which are loosely connected with the inner end portions 10 of said web or ribs by the cross pins 11. The fiat top portion 6 at each end of the cross tie which forms a support for the rail is provided at opposite ends and at diagonally opposite points with the longitudinal slots 13 and the vertical apertures 14; which are spaced inwardly of said slots and are arranged in longitudinal alinement therewith.

The rail fastening plates 3 which are of substantially triangular form, are recessed or cut away at their inner ends, as at 15, to receive the base of the rails and are provided at their outer ends with the depending portions or extensions 16 which project through and below and work in the longitudinal slots 13 in the top portions 6 of the rail and hold them against any rotary or turning movement when in normal position or when moved in either direction, to engage or disengage the rails. The rail fastening plates, as shown, are provided with the central longitudinal slots 17 through which pass the bolts 18, which are inserted through the vertical apertures 14 in the top portions of the cross tie with their heads fitting against the bottom faces of said top portions and their upper threaded ends projecting above the tops of the fastening plates to receive the nuts 19 which are screwed against the 22 in the upper ends of the keepers 23, theinner ends of said adjusting screws bearing against the outer ends or heels of the fastenlng plates. As shown, the keepers 23 are provided with reduced central portions 24 which pass through the slots 13 and fit against the outer end walls thereof and are also orovided at their lower ends with heads 25 w ich extend across the slotted portions 13 of the top members 6 of the cross tie and fit against the bottom faces thereof whereby the keepers are held in position.

The cross tie may be increased or decreased proportionately in length and other dimensions, making it suitable to wide or narrow gage track in order that it may support either heavy or light equipment according to trafiic conditions as used in modern railways. It is also pointed out that the form of rod A and the tie shown permits the latter to have a free movement or cushioning and resilient effect on each rail. WVith this end in view, one section, as a of said rod is provided at its inner end with a fork 0 which receives the inner end of the other section b of the rod. A coil or helical spring (Z is disposed around the forked end of section a and bearing against the outer end of said spring is an oblong washer or plate 6 which is formed with a central transverse aperture c to receive the inner end of rod section b and works between the two tines or members of the fork 0 of rod section a. A nut is screwed on the inner end of rod section 6 to secure the latter in place while the inner ends of the tines 0 of rod section a are formed with outwardly bent lugs or hooks g to hold the coil spring in place.

From the foregoing, it will be seen that in view of the yielding connection between the inner ends ofthe rod sections a and b, the rod 'A does not'interfere with the resilient or cushioning action of the cross tie under the rails while the coil spring facili tates the return of the tie to normal position after the train has passed, under which con- -ditions the rod A provides a reinforcement for the central cut-away portion of the tie. Having described our invention, what we claim as new and desire to secure by Letters Patent, is

In combination, a metallic cross tie having a flat base and flat top portions at opposite ends thereof, supported upon and above the base by vertical legs and a central upright longitudinally disposed web, said web being cut away for the greater part of its width between the top portions of the tie and a connecting rod loosely connected at opposite ends with the inner ends of said top portions, said rod comprising two sections slidably connected together at their inner ends.

In testimony whereof we aflix oursignatures in the presence of two witnesses.
