METAL RAILWAY 'TIE.

Application filed June 19, 1924. Serial No. 721,048.

=- skilled in he art to which it appertainsto make and use the same.

My invention relates to improvements in metal railway ties and has for its object to provide a greatly improved tie construction in which the rails will be yieldably supported and secured in place in an exceptionally simple, yet efficient manner.

lVith the foregoing in view, the invention resides in the novel subject matter hereinafter described and claimed, the description being supplemented by the accompanying drawing.

Figure 1 is a top plan view partly in horizontal section.

Figure 2 is a partial side elevation.

Figure 3 is a detail longitudinal sectional view as indicated by line 3-8 of Fig. 1.

Figure 4 is a detail transverse sectional view as indicated by line 44 of Fig. 1.

Figure 5 is a fragmentary perspective view.

In the drawing above briefly described, the numeral 1. designates an elongated metal. base which is preferably formed of a horizontal plate having downturned edges 2 which may be notched at intervals as indicated at 3. The lower side of the plate is preferably formed with a longitudinal rib 4 and transverse ribs 5 which reinforce said plate and co-act with its downturned edges indholding it against slippage on the road be Extending across each end of the base 1, is a metal open-topped casing 6 whose end walls 7 preferably project downwardly below the upper side of the base 1 and are secured against opposite edges of said base, as indicated at 8. The lower edges 9 of the casing sides 10 are preferably directed outwardly in the form of flanges which are secured upon the top of the base 1. While these details are preferable for securing the casings 6 to the base of the tie, they are not absolutely essential, as the casings and base may be secured together in any adequate manner.

The side walls 10 are of greater height than the end walls 7 and they preferably have their projecting upper edge portions thicke'nedas indicated at 11, and provided with outwardly extending longitudinal flanges 19-, said flanges and the adjacent portions of said side walls, being provided at suitable intervals with transverse notches 13. A rail-supporting block 14, preferably formed of wood, is received'in each of the. casings 6 and has its top surface below the bottoms of the notches 13, 'but above the. upper edges of the-end walls 7, the latter relation permitting the blocks to yieldably support the rails, without permitting the latter to come into contact with said end walls 7.

Contacting with the outer sides of the walls 10, and extending under the outwardly pro ecting flanges 12 are clamping bars 15, apair of these bars being provided for each casing 6. The upper edges of these bars are provided with rail-holding tongues 16 which extend inwardly through the notches 13, and the ends of said bars extend beyond the easings 6 and are formed with boltholes 17, as well as with additional rail-holding tongues 18. Transverse bolts 19 are passed through the openings 17 and are located at the ends of the casings 6, and when said bolts are tightened, the bars 15 are effectively held in place and their projecting ends, which ends are preferably thickened on their inner sides, are frictionally bound against the edges of the rail bases, so as to hold the rails against creeping.

If desired, the blocks 14 and the end walls 7, may have alined openings 20 formed therethrough, to receive signal wires or the like.

By providing the construction shown and described, or a substantial equivalent thereof, a simple, yet efficient tie is provided which will effectively clamp the rails in place, yet will yieldably support them in a manner greatly advantageous over the common all metal tie. As excellent results may be obtained from the details disclosed, they may be followed. but within the scope of the invention as claimed, minor changes may be made. For instance, in some forms of the invention, the base 1 and the two casings 6, may be integrally connected.

I claim:

1. A railway tie comprising a base, an open-topped casing on said base having parallel side walls provided with outwardly direeted longitudinal flanges at their upper edges, said flanges having transverse notches, a railsupporting block in said casing, a pair of horizontal clamping bars contacting with the outer sides of said side Walls under said flanges and having rail-holding tongues eX- tending inwardly through the notches of said flanges, and means for holding said bars in operative position. n I

2. A railway tie comprising a base, an open-topped casing on said base having parallel side walls provided with outwardly directed longitudinal flanges at their upper edges, said flanges having transverse notches, a rail-supporting block in said casing. a pair of horizontal clamping bars contacting with the outer sides of said side walls under said flanges and having rail-holding tongues extending inwardly through the notches of said flanges, said bars projecting beyond the ends of said casing, and transverse bolts at the ends of said casing passing through the ends of said bars for clamping them in operative position and binding their ends against the edgesof the rail base.

A structure as specified in claim 2; the projecting ends of said bars having additional rail-holding tongues.

4. A railway tie comprising a base, an elongated open-topped casing extending across said base and having end walls which extend downwardly beyond the top of the base and are secured to opposite edges of said base, said casing having parallel. side Walls whose lower edges are formed with horizontal flanges secured to the upper side of the base. a rail-supporting block in said casing, and means for securing a rail in place upon said block.

In testimony whereof I have hereunto atfixed my signature.
