To all whom it may concern:

Be it known that I, CHARLES D. SMITH, citizen of the United States, residing at Birmingham, Alabama, have invented certain new and useful Improvements in Railway of which the following is a specification.

My invention relates to new and useful improvements in railway cross ties or sleepers, and especially to those made of'reinforced concrete. I "1 The advantages of the reinforced concrete tie over wood, especially in'the matter of durability, is well known, but heretofore such concrete ties have not gone into extensive use due to certain inherent defects in their construction.

\I have aimed, in the present invention, to provide a concrete cross tie in which provision will be made for slight motion in-the ties'while the train is passing over them,

tacha'bly connected together .-by the rein forcing rods 2-- and' 2, which are embedded in the sections in the process of molding, and are provided at their extremities with, hooks and eyes .3 and 4, respectively, by whlch the sections are detachably connected together. They-are further connected by a. p n 2" 'molded in and projecting from one of thesections and engaging a corresponding recess in the other section. The hooks and eyes ofthe two sets of rods are prefer,- ably reversely arranged, that is, on one side of. thetie one rod 2 carries the hook, and theother 2 the eye, while'on the opposite side of the tie the first named rod carries the eye and the second the hook. The hinged joint formed bythe hook and eye connection comesdirectly beneath the line of contact between the abutting portions (2 and a, and this, together with the cut away portions-below the joint, enables the ends of thus securing the equivalent of the slight elacticity-of the wood tie.

A further object is to provide a tie made of two parts which are exact duplicates of each other, and which Ina-v be shipped detached and readily assembled, vthereby greatly facilitating the handling in shipment, the great we ght of the ordinary full length concrete tie being a'serious drawback. A further object is to provide a novel 5 form I of reinforcing means which also plays a part in securing the two sections of the tie together, and still another object is to provide, in connection with a tie of this character, simple and eflicient means for secur- 'ing the rails thereto.

With these andother objects in View, the invention consists in the novelfeatures of construction and combination and arrangement of parts hereinafter described and particularly defined in the appended claims A cross tie constructed in accordance with my invention isillustrated in the acc0mpanying drawings, in which-- Figure 1 is a plan view; Fig. 2 is a side .elevation-'; ,-and' Figs. 3 and 4 are detail views. Fig. 5. is a: View of a modified form. [Referring by reference characters to this. drawing, thenumerals 1 and 1* designate the two sections of the improved cross tie, which are molded to be substantial dup1icates of" each other, and having abutting portions a and a", and lower cutaway porthe joint chairs, or rail joints, or plate.

BIRMINGHAM,

vided in this widened out portion, as indicatedbythe numeral 7, these cross rods being arranged in pairs with the ends turned toward each other to secure the anchoring efi'ect, asindicated'at 7?. When desired, cermm of the sections may be molded short on one. side, as indicated in Fig. 5, whereby two ties may be placed close together at the, rail joint, the short wings serving to engage In order to secure the; rails to the ties, I provideeach section of the tie in molding with a recess 8 which'has parallel side walls and endwalls which flare outwardly-and downwardly, as indicated at 8. -Within this recess I place a.wooden block 9 which has parallel side walls corresponding to the side walls of the recess, and downwardly flaring end walls. The length ofblock at tlons Band 6. Ihe se two sections are dethe bottom is equalto the length of the re I provi adapted for detachable connection and when cess at the top, so that the block may be easily inserted in the recess, and when lodged therein, leaves an inclined space at each end. Into this I pour a compound composed of hot coal tar and sand which will harden when cooling, and which, filling in around the wood block, serves to hold the same in position. Over this wood block I place a' rail supporting plate 10 provided with holes for the reception of spikes, and secure the rail in place by'driving the spikes 11 through the plate into the wood block.

Instea of using spikes I may use a steel clamp fastening'as shown on the left hand side of Figs. 1 and 2, in which plates or bars 12 are provided having upper ends 12 designed to be bolted to opposite sides of the web of the rail, and inclined portions 12 resting upon the base of the rail. Below the said ase the bars are provided with downwardly extending endshaving out-- wardly turned hooked ends 12 designed to hook under the cross reinforcing rods 7.

Having .thus described my invention what I claim is:

1. A railroad tie comprising a pair of du licat'e concrete sections, longitudinal ro s anchored in each section, said rods projectin from the ends of said sections and ed respectively with hooks and eyes holding said sections abutting against each other, said sections having undercut, poi;

tions adjacentthe projecting ends of' the rods permitting a downward flexing motion of the outer ends of the sections, substantially as described. .2. A railroad tie comprising a pair of duplicate "concrete sections, longitudinal rods anchored in each section. said rods projecting from the ends of said sections and provided respectively with hooks and eyes adapted for detachable connection, said sections hm'ingalmtting portions and undercut portions adjacent the projecting ends of the rods, and a pin pro ect ing from the abutting portion of the end of one sect-ion and engaging a hole in the abutting portion of the other section, substantially as described.

3. A railroad tie comprising a pair of concrete sections detachably connected together, said sections having cross reinforcd an tie bars adapted to' be bolted to .opposite sides of the rail, and having hooked ends depending in said recesses and engaging said cross rods.

- Intestimony whereof I aflix my signature in presence of two witnesses.
