REINFORCED-CONCRETE CROSS-TIE.

Specification of Letters Patent. Patented May 28,1912.

Application filed January 16, 1911. Serial No. 602,962.

To all whom it may concern:

Be it known that I, ALBERT F. WILSON, a citizen of the United States, and a resident of the city and county of Montgomery, State of Alabama, have invented certain new and useful Improvements in Reinforced-Concrete CrossTies, of which this is a specification, reference being had to the accompanying drawing, forming part hereof.

The invention relates to reinforced crossties of concrete and the like intended for railways and the object of the invention is to providea simple, durable and economical article of this class which will possess sufiicient elasticity to avoidthe cracking or disintegrating heretofore found to accompany the use of reinforcedconcrete and the like in this connection.

A further obj ectis to provide in combination with a tie of the character to be set forth means of attachment of the rails whereby the advantages sought will be more certainly secured.

In the drawing Figure 1 shows a perspective view of a cross-tie employing a general feature of the invention-the resilient connection; Fig. 2 shows two half ties, and illustrates the position of the reinforcing members; Fig. 3 shows a modification of the rail-holding means and its attachment to the reinforcement; Fig. 4 shows a perspective view of the reinforcement and a the rail-holding means of Fig. 2; and Fig. 5 shows a modified reinforcement. in plan.

Fig. 1 illustrates an important feature of the invention-the resilient connection between the two mated concrete sections, the sections,'1, 1, being joined by a resilient member 2 which may also serve as reinforcement. This member is sufiiciently rigid to preserve the blocks 1, 1, at a fixed distance but allows considerable vertical displacement. Member 2 is ordinarily made of flat spring steel and may be extended at its ends to form reinforcements but I prefer to join its ends (see Figs. '2, 3, 4, 5), by rivets or otherwise, to less expensive-reinforcements.

See particularly Figs. 2 and 4. I may employ one or more reinforcing members in each section.

Fig. 2, to the left shows the reinforcing member as a flat plate 3, fastened to the member 2. This structure is suitable for right Fig. 2 shows the preferred constructhe rail-holding means of Fig. 3. To the tion-a combination of reinforcement and rail holding means. v Here, as shown indotted lines, the reinforcing member 3 is extended upwardly to form at 3 a rail engaging lug, between which and a plate 4 on the other side of the rail 5 the rail may besecured as by a bolt or bolts as shown in the figure. I preferably place the rail on a block of wood or other suitable material set into the concrete section, see 7 ,7 Fig. 2. Through this block 7 extend bolts 6, 6, binding it to the tie.

The construction shown in Fig. 3 is somewhat different but it will be seen that the essential features are present. Here there are two plates or rail engaging members,"4, 4,

between which the rail 5 is held. These plates or members are held against the cushioning block 7 and the tie section by bolts, .6, 6, as in Fig. 2. The reinforcement is connected by these bolts passing through it as will be seen.

Fig. 4 shows the arrangement of the reinforcing member to function also as a rail securing device. Here the member 3 1s bent upwardly over the cushioning block 7, the portion 3 being suitably shaped to fit't-he rail 5 (here shown partly in perspective.)

I-providein all cases a fastening for the rail which will permit of longitudinal movement of the rail with reference to the tie, to permit of the movements due to expansion and contraction of the rails.

While I have shown an approved formof rail securing means yet it is obvious that my invention is not llmlted 1H practice to any particular devices of this class, as an elastically coupled concrete tie may be employed with substantially all known means of rail attachment capable of use in the structure employed.

In Fig. 5 I have given a general illustration of what I conceive to be an important feature of the invention. Here the view is a plan of the elastic connecting member (only a portion being shown) and one of the reinforcing members. The reinforcing member is shown attached, as in the preferred practice, to the reinforcement by rivets as at 9, 9. To secure efficient anchorage of the reinforcing member in the con- 1 crete of the block I provide extensions 3", r

8", 3", 3 (as many as may be desired) or otherwise provide means whereby the reinforcement will be securely held by the concrete. The drawing sufficiently shows the idea; to allow the reinforcing element to ramify through the block. Toward the right hand end of the reinforcement are holes 20, 20, referred to above, and which may serve to receive bolts or equivalents such as used in the apparatus of Fig. 3.

Having described my invention, what I claim is:

1. A concrete cross-tie including mating sections, and reinforcing members embedded in said sections and having their inner ends resiliently united and their outer ends ex tended beyond the top of the tie in position to engage the web of a rail.

2. A concrete cr0ss-tie including mating sections, reinforcing means terminating above said sections and partly embedded in said sections and resiliently joined bet-ween said sections.

3. A concrete cross-tie embracing two mating sections, a reinforcing member embedded in each section and extended upward beyond the top of said section, and a resilient member connected to each of said reinforcing members between the ends of the tie, substantially as shown.

4. A concrete cross-tie embracing two like end sections, reinforcements embedded in each section and provided with ends adapted to engage a rail, and a resilient member connected to the reinforcement of each of said two sect-ions, substantially as shown.

5. A reinforced concrete cross-tie, comprising two mated concrete sections, a reinforcement terminating in a rail engaging lug embedded in each of said sections, and a resilient member connected at each end to said reinforcements.

6. A reinforced concrete cross-tie, comprising two mated sections of concrete, rail engaging means on each of said sections, a resilient member between said concrete sections, and a reinforcement embedded in each of said sections and connected at one end to said resilient member and'at the other to said rail engaging means.
