REENFORCED CONCRETE RAILRGAD TEE AND RAIL FASTENER.

Application filed September 20, 1927.

This invention relates to reenforced concrete railway ties and has for one of its objects to provide reenforceznent means which will protect the tie from any breakage which might result from the weight and vibration of trains passing over the same and having associated therewith a simple and efficient means for securing a rail in position on the tie.

A further object, is to provide an article of this character of simple and practical construction, efficient and reliable in performance relatively inexpensive to manufacture, enabling the rail to be easily and quickly secured in position thereon, and otherwise well adapted for the purposes for which the same is intended.

Other objects and advantages reside in the special construction and combination of the various elements forming the invention, reference being had to the accompanying draw: ings. wherein Figure 1 is a side elevational view of a tie constructed in accordance with my in vention with parts shown in vertical section to illustrate the rail fastening means.

Figure 2 is a vertical sectional view through the tie and fastener taken along a line 22 of Figure 1.

Figure 3 is a bottom plan view of the tie illustrating one of the rail fastening recesses formed in the base thereof.

Figure 4 is a top plan view illustrating the supporting plate for the rail, and adjacent slotted openings for receiving the rail fastening means.

Figure 5 is a similar view showing the rail in secured position thereon, and,

Figure 6 is an elevational view of one of thefastening lugs abutting plates provided along the upper edge of the slotted opening to prevent the chipping of the concrete.

Referring now to the drawing in detail, my invention comprises a railway tie indicated generally at 5, preferably constructed of concrete or other suitable hardened composition and provided with angular reenforcing rods 6 imbedded in the tie and eX- tending substantially throughout the length thereof.

At a proper position adjacent the ends of the tie for arranging the rails 7 of a predetermined gage, the tie is provided with a pair of vertically extending slotted openings 8, with the slotted portions thereof extending longitudinally with respect to the Serial No. 220,703.

tie and separated by a bridge portion 9 coinmunicating with the opposite sides of the tie and co-acting with such side portions to form a seat for the rail 7.

The lower portions of the slots 8 are connected by a longitudinally extending recess 10 which underlies the bridge portion 9 so that the face of the bridge portion is arranged inwardly of the bottom edge of the tie. A metallic plate ll is interposed be tween the rail 7 and the upper face of the bridge portion 9 and is fixedly secured in position with respect thereto by means of dowel pins '12 or the like. In the upper face of the tie adjacent each side of the bridge portion are recesses whereby to receive the plate 11 so that the upper face of said plate will occupy a horizontal plane with the upper edge of the tie.

The ends of the slotted openings 8 remote from the bridge portion are enlarged as indicated at 13 enabling the head 1- of a bolt 15 to be inserted therein, after which the shank of the bolt 1:) is moved inwardly toward the rail.

A pair 'of longitudinally extending plates 17 are recessed in the inner walls of the recesses 8, arranged under the lower portion of the bridge 9 and disposed in spaced parallel relation with respect to each other whereby to permit the bolt 15 to extend therebetween with the head lat retained against the underside of said plates. The upper ends of the bolts 15 extend through clamps 18 disposed at opposite sides of the rail 7. with one edge of said clamps adapted to engage the flange of the rail with the opposite cnd thereof extending over the slotted opening 8 so as to substantially cover the same and seated upon the upper face of the tie about the edges of said slot. The under side of the clamp 18 provided with a boss 19 adapted to be inserted in the upper end of the slotted opening by means of which the lug may be securely retained in position i transverse slipping movement with The outer end of the slotted opening 8 along the upper edge there of is fitted with a dove-tailed plate 20 disposed so as to permit the boss 19 on the clamp to abut thercagainst whereby to prevent chipping of the upper corner of the recess.

It. will be apparent from an inspection of Figures 1 and 2 of the drawing that upon arranging the bolts 15 in the recesses as indicated and placing the clamps 18 at the upper ends thereof, that the parts may be securely retained in position by means of the nuts 21 arranged on the upper end of the bolt. Such construction not only provides a positive and secure means for attaching the rails to the tie but furthermore enables the parts to be easily and quickly replaced should the same become worn, corroded or otherwise damaged.

It will also be apparent that in the construction of the tie the recess provided tor receiving the plate 11 may be properly positioned for securing the rails at a predetermined. gage "'thout necessitating the use ot a gage i1 talent in order to insure the spacing oil? the rails in properly spaced relalion.

It is obvious that the invention susceptible of various changes and nioditications Without departing from the spirit or scope oi the invention as hereinafter claimed. or sacrificing any ot its :nlvantages, and l. arcordingly claim all suchytorms o l' the device to which 1 am entitled.

liiaving thus described my invention, what I claim as new is 1. A railway tie having recesses arranged adjacent each end thereof, said recesses being arranged in pairs and extending vertically entirely througl'i the tie, a bridge separating the recesses of each pair, a recess formed beneath each bridge providing connnunication rail retaining bolts arranged within each of 7 said vertical recesses, with their lower ends engaging the adjacent edges of said plate.

2. A railway tie having a pair of vertically disposed recesses tor-med 'abljacent each end thereof and extending entirely therethrough, a bridge extending transversely of the tie dctining the limitation of said recesses ot each pair, with the ends Oil said sees remote "trom the bridge of an enlarged area, a recess arranged beneath the bridge having horizontally disposed grooves termed in the walls thereof, a pair of spaced apart plates extending longitudinally of the tie beneath the bridges, with the ends there of disposed within said recesses, and their side edges seated in said grooves whereby to support the plates in horizontal position, and a rail attaching bolt arranged within each e't raid recesses having a head at the lower end thereot insertable through the enlarged portion ot the recess and adapted to engage Lhe adjacent edges ot. each of said plates, the upper end of said bolt being arranged for attachment with the rail supported on said bridge.

In testimony whereot I afiix my signature.
