Application led May 17, 1920. Serial No. 381,855.

To all whom t may concern: Y

Be it known that I, IVILLIAM F. MORRISON, a citizen of the United States, residing at Vallejo, in the county of Solano and State of California, have invented new and useful Improvements in Concrete rIies, of which the following is a specification.

This invention relates to improvements in concrete railroad ties and has for its primary object the provision of a concrete tie which will be durable, strong, and reliable in holding the rails against spreading,`which will provide the desired amount of resiliency and which will'provide for an easy and expeditious mounting and removing of the rails.

Another object of the invention is to provide a tie of the character described, which is comparatively simple as to construction, relatively inexpensive, and of compact form.

rIhe invention possesses other advantages and features, some of which with the foregoing, will be set forth at length in the following description wherein I shall outline in full that form of the invention which I have selected for illustration in the drawings accompanying and forming a part of the present specification. In said drawings, I have shown one form of the construction of my invention, but it is to bev understood that I do not limit myself to such form, since the invention as expressed in the claims may be embodied in a plurality of forms.

Figure 1 is a top plan view of the tie of my invention;

Fig. 2 is a side elevation of the tie;

Fig. 3 is a sectional view taken On the line 3-3 of Fig. l;

Fig. 4L is a sectional view taken on the line t-lf of Fig. 1;

Fig. 5 is a sectional View taken on the line 5 5 of Fig. 2;

Fig. 6 is a sectional view taken line 6 6 of Fig. 3.

The present embodiment of the invention as illustrated in the drawings, comprises a rectangular concrete tie 7 of the usual outline,having cushion plate receiving recesses S near each end, in which recesses are mounted wooden cushion plates 9.

Mounted on the plates 9 are metal rail supporting plates 10 having depending side flanges 11 which engage the sides of the plates 9 and sides of the tie 7. Bolts on the 12 are embedded in the concrete tie and eX- tend upwardly through the plates 9 and 10 near the ends of the plates and have nuts 13 turned on their upper ends. These nuts and bolts hold the plates firmly and securely in place.

Angular rail clamps 111- are secured by bolts l5 to the plate 10 and are held in place by nuts 1G turned on the bolts. These clamps hold the rails upon the tie and are easily operable to remove to secure rails in place.

To strengthen the tie and hold the rail supporting elements thereof, against spread-- ing, there are embedded longitudinally in the tie, metal rods 17 whose intermediate portions 18 are upwardly off-set providing spaced shoulders 19 at points under opposed ends of the plates 9 and 10. Downwardly bowed metal rods 2O are embedded in the tie beneath the portions 18 of the rods 17 and their ends engage the shoulders 19. This arrangement of reinforcing rods provides maximum resiliency and takes up all stresses evenly as well as to strengthen the tie generally.

Ilrom the shoulders 19 the rods 17 extend downwardly and forwardly at an angle and are then arched as at 20 the uppermost portion of the arch engaging the rail supporting means as shown in Fig. e whereby the strain as transmitted from trains passing over the rails is taken up by said arch and breaking off of the outer ends of the tie prevented. From the outer ends of the arches the ends of the rods '17 are bent upwardly and inwardly and engage the plates 22. The plates 22 are provided with headed members 23 which are embedded in the concrete body and these plates engage the edges of the rail supporting members. By this' arrangement of reinforcing rods relative to the railsupporting members the entire structure is made more durable, stronger, more resilient and spreading of the rails is positively prevented.

It will therefore be seen, that I have provided a simple, inexpensive railroad tie which can be easily and quickly manufactured, and which will combine the desirable characteristics of a wooden tie with the advantages in strength, and durability offered by concrete and metal.

I claim 1. A railway tic comprising a concrete body, rail supporting members on the body,

metal-reinforcing rods embedded longitudinally in the body and having mediate portions offset and forming spaced shoulders, and bowed rods embeddedin the tievv with their ,.ends abutting the shoulders on the first-named rods.

2. A railway tie comprising a concreteAV body, rail supporting members on the body,

metal reinforcing rods embedded longitudinallyV in the body and having mediate portions offset and forming spaced shoulders, and bowed rodsv embedded in the tie with their ends` abutting the shoulders on the lirst-named rods, the ends of said first-named lrods being directed upwardly and operatively engaged with 'the rail supporting y members. Y

.. 3*. A railwayy tie comprising a concrete body, rail supporting members on the body,

metalrreinforcing rods embedded longitudinallyy inthe body andhaving mediate portions offsetv and forming spaced shoulders, and bowed rodseinbedded inthe tie with their ends abutting the shoulders on the first-named rods, plates anchored' in said body and labutting said ra-il supporting members, .said lfirst-named rods having their ends bent upwardly and inwardly andy abutting said plates.

4l Af railway tie comprising a concrete body,-rail'supporting'plates mounted on the body, and plates anchored to the body and abutting the outer ends o'f said plates and longitudinal reinforcing rods embedded in the body and having upwardly andk inwardly turned ends abutting said plates.

5. A railway tie comprising a concrete body, rail supporting members mounted upon theb body longitudinally and reinforcing rods embedded in the body and having upwardly arched portions adjacent therein and engaging under said rail supportingV plates. Y
