Specification of Letters Patent.

Application filed August 15, 1917. Serial No. 186,370. i

in a concrete cross tie and has for one of its objects the provisionof. a device of this character, which will have a great quantity ,of elasticity and still maintain its durability 4 Another object of this invention is to provide a resilient supporting and securing member'gfor therails upon the body of the tie,- whereby a give will be had to the rails when a train. or car is passing thereover.

A further object of this invention is the provision of means to prevent the spreading of the rails while under a load.

A still further object-of this invention is the provision of a railroad concrete cross tie of the above stated character, which shall ,.be simple, durable and eflicient, and which may be manufactured and sold at a comparatively low cost.

With these and other objects in view as will become more apparent as the description proceeds, the invention consists in certain novel features of construction, combination and arrangement of parts as will be hereinafter more fully described and claimed. 4 Y For acomplete understanding of my invention, reference is to'be had to the following description and accompanying drawing, in which: i

Figure 1 is a longitudinal sectional view of a railroad track illustrating concrete cross ties constructed in accordance with my invention,

v Fig. 2 is a vertical sectional view of the tie illustrating the means for supporting the rails, i

Fig. 3 is a transverse sectional view taken on the line 3-3 of Fig. 2, I

Fig. 4: is a similar View taken on the line 4+4 of Fig. 2,

' Fig. 5 is a fragmentary perspective view of the means for securing the rails to the Fig. 6 is a vertical sectional view of a modified form of tie.

Referring in detail to the drawing, the numeral 1 indicates the body of a tie, which is constructed from concrete and has molded therein, securing bolts 2. The securing bolts 2 are relatively spaced and positioned at a point intermediate the ends of the body of the tie. The upper face of the tie is provided with a recess 3, forming end shoulders 1 to the body of the tie. Recesses 5 are'located in the bottom wall of the recess 3 adjacent each end thereof and have positioned therein, coiled springs 6. Drain passages extend through the body from each end thereof in communication with the recesses 5 for the purpose of permitting water and other foreign matter to drain therefrom. v

A resilient supporting member 8 is secured to the body 1 by means of the bolts 2 and has its ends disposed over the coiled springs 6, which sup-port the ends of the supporting member in spaced relation to the bottom wall ofthe recess 8. The free ends of the supporting member 8 are bent to form retaining clamps 9 that engage the outer flanges of rails 10. Removable clamps 11 engage the inner fianges of the rails and moving upwardly and downwardly to add resiliency to the rails when a car or train is passing thereover. A guard 13 is secured to the body 1 of the tie by the bolts 2 as clearly shown in Fig. 2 and is provided with an ofiset portion 14 that overlies the supporting member 8, which protects said member and permits the same to move upwardly and downwardly freely with relation to the body 1 of the tie. Downwardly and outwardly extending flanges 15 are formed upon the guard 13 and normally rest upon the upper face of the body 1 of the tie.

From the foregoing description taken in connection with the'accompanying drawing, it will be noted that a novel form of concrete tie has been provided, which will have greater elasticitythan the ordinary wooden tie and of greater durability. It will also be noted that the rails 10 will be prevented from spreading while under strain or load.

to the body 1 of the tie and are capable of inner end of the other section is convex so that the sections fit one within the other which structure will permit one section to move upwardly and downwardly with relation to the other section, this form of tie being preferably employed where road beds are constructed upon soft or muddy ground so that one end of the tie is capable of adjusting itself without affecting the other end. I

While I have shown and described the preferred embodiment of my invention, it will be understood that minor changes in construction, combination and arrangement of parts maybe made without departing from the spirit and scope of the invention as claimed.

Having thus described my invention, what I claim is 1. A railroad tie comprising a concrete body having a longitudinal recess in the upper face thereof, a resilient supporting member. located within said recess and secured to the body,-and means securing rails {)0 each end of the resilient supporting mem- 2. -A railroad tie comprising a concrete body having a longitudinal recess in the upper face thereof, a resilient supporting member secured to the body within said recess, said body having recesses in communi cation with the longitudinal recess adjacent each end thereof, coiled springs located within the last named recesses and supportmg the free ends of the resillent supporting member, and means securmg ralls to the ends of the supporting member.

3. A railroad tie comprising a body, a resilient supporting member secured to said body, cushioning means supporting the free ends of the supporting member, said supporting member having its free ends bent to form clamps to engage rails, and removable clamps secured to the supporting member and engaging the rails. I

4. A railroad tie comprising a body, aresilient supporting member secured to said body, means securing rails to said supporting member, and a guard secured to said body intermediate its end'sand overlying the supporting member to prevent foreign mat: ter from becoming lodged between the body and the supporting member and which will permit free movement of said supporting member.

5. A railroad tie comprising a body, a resilient supporting member secured to said body, means securing rails to said supporting member, and a guard secured to said body intermediate its ends and overlying the supporting member, said body having the top wall of its upper free ends spaced from the body to permit free movement of the ends of the supporting member.

In testimony whereof I affix my signature in presence of two witnesses.
