METALLIC TIE AND RAIL CLA MP THEREFOR.

Application filed April 3, 1928. Serial not 267,077.

The present invention relates to railroad ties, and has for its principal ob ect to pro-' vide an article of this character constructed of metal and to provide means arranged thereon. for fastening the rail in position upon the tie.

A further ob ect of the invention 18 to provide a hollow metallic railroad tie adapted to support a pair of rails upon its upper face,

and forming the portion of the tie immediately beneath the rail of a solid construction, whereby to. increase the strength of the tie at that portion subjected to the most strain.

A still further object is to provide an article of this character of a simple and practical construction, which is strong and durable, in which the weight of the tie is materially reduced, which is comparatively inexpensive to manufacture, permits of the ready placing and removalof the rail in position thereon,

and which is otherwise well adapted for the.

purposes for which the same is intended.

Other objects and advantages reside in the special construction and combinationof the various elements comprising thev invention, reference being had to the accompanying drawings, forming a part thereof, wherein:

Figure 1 is a top plan view of a tie,con-e strncted in accordance with my invention and showing a. pair'of rails secured in position tl'iereupon. I

Figure 2 is a side elevat-ionalviewthereof.

Figure 3 is a longitudinal sectional view,

taken substantially along the line -3--3 of Figure-1. Y 7

Figure 1 is. a vertical sectional View, taken. along the line 4-4 of Figure 2. r

Figure?) is a similar view, taken along the line 55 of Figure 3, and

Figure 6 is a perspective viewof one of the rail clamping plates.

Referring now to the drawing in detail, the invention comprises a railroad tie, constructed of metal and of a hollow formation. 'A pair of rails 5 are adapted to seat upon the top 6, of the tie, adjacent the ends thereof,

i the outer flange 7 of each of the rails'being engaged by upwardly and inwardly inclined lugs 8, cast integrally withthe tie and formed at the side edges of the'top portion 6-tl1ereof.

The center portion ofthe t-ie, between the! rails 5 has its top portion open, as shown at 9, andwith the sides 10 adjacent such opened portions,'reduced in height as is shown atll.

The inner flange 12 of each of the rails 5 is engaged by a fiangededge 13, formed on a retaining plate 14, adapted to seat upon the top portion Got the tie, along the edge of the opening 9., formed in the top and at each end thereof. The plates lat and the top portion 6 of the .tie are providedwith aligned openings 15, through which bolts 16, may be inserted for securing the plates in a fixed position upon the tie, so as to secure the rail against movement thereon. v

The portion of the tie immediately beneath the rails 5 is constructed in a solid formation as shown. at'l'i', whereby to provide a reinforced foundation for the rails. In this manner, suliicient strength is provided for bear ing the weight of the train as the same passes over the rails and at the same time permitof considerable economy in the'construction. of

' the tie, which otherwiseis of a hollow form-arails upon its upper surface and with thetupper portion of the tie between the rails open, said the being of a solidconstructlon at the portion thereof immediately, beneath the rails, a pair of rail flange engaging lugs formed integrally with the tie and adapted to engage the outer flange of each of said rails, a railattaching plate engaging the inner flange of each of said rails, and bolts upwardly through the portion of the upper surface of the tie, adj acent the solid construction thereof forvsecuring the plates in, position, said tie having .its side walls bet-ween the rails I reduced whereby to afford access to said bolts for Working the bolts of therail from a position between the rails.

In testimony whereof I aflix my signature.

JOHN L. CARTMELL,
