DAVID S. BEACH, OF BRIDGEPORT, CONNECTICUT.

RAILROAD-TIE.

Specification of Letters Patent.

Patented Apr. 2.3, 1912.

Application led August 15, 1910. Serial No. 577,357.

To all 'ir/01a it may concern Be it known that I, I).\vu) S. BEACH, a citizen of the lluited States, residing at Bridgeport, county of Fairfield, State of Connecticut. have invented an Improvement in Itailroadfllies, of which the following is a specification.

This invention has for its object to provide a concrete or artificial stone railroad tie having resilient means for supporting the rail so that full advantage may be taken of the strength and durability of concrete as a material for ties` while at the same time the noise and deadness of ordinary stone or concrete ties shall be avoided.

lith these and other objects in view I have devised the novel concrete railroad tie, of which the following description in connection with the accompanying drawings is a specification, reference characters being used to indicate the several parts.

Figure 1 is an elevation of one of my novel ties as in use` the rails, guard rails and clamping plates being in section and the ends of the tie being in section as on the line 1*-1 in Fig. Q; Fig. 2 an end elevation of a tie showing a rail and guard rail in elcvation; Fig. 3 a plan view of a guard rail plate detached; Fig. 4 a longitudinal section of one end of a tic illustrating a variant form of the invention; and Fig. 5 is a transverse section on the line 545 in Fig. 4A.

10 denotes the body of my novel tie Which is molded from concrete to any required forni.

l1 denotes reinforcing rods which are disposed longitudinally in the ties and molded therein in any number required, four being shown in the drawings and being considered quite sutlicient. In addition to these reinforcing rods I provide approximately centrally in the ties and longitudinallyy thereof a series of supporting rods 1Q, four being shown in the present instance. These rods 12 form the support, in addition to the concrete itself, of heavy springs 13 which are seated in recesses 14 in the upper side of the tie and extend above the body, the recesses extending down to the upper sides of the supporting rods so that the springs rest both on the concrete and on the rods.

15 denotes rails, and 16 guard rails nlhich may or may not be used but are provided for as part of the present invention. The rails rest upon carrying plates 17 which in turn rest upon the springs. The rails are locked to the carlying plates by means of clamping plates 1S which engage the bases of the rails. The rails, clamping plates and carrying plates are secured together and said parts are retained against difailacement by bolts 1U which pass through the clamping plates, the carrying plates and thc tie. The heads of the bolts are shown as lying on the underside of the ti i, and the threaded ends projecting above the clamping plate and engaged by nuts 2O and set nuts 21. In order to lessen the noise and avoid an absolutely rigid connection of these parts, I preferably place spring washers 22 under nuts Q0.

Guard rails, when used, are carried by guard rail plates 2?), shown as slotted, the ends of which rest upon the inner ends of plates 1T which are shown as extended for that purpose. The guard rail plates are secured to plates 1T by means of bolts il and the guard rails are secured to the guard rail plates by means of clamping platesl and bolts 2G which pass through the clamping plates, the outer bolts passing through the slot in plate Q3 and through plates- 1T and the inner bolts passing through the clamping plates and the slot in plate Q?) only and sliding freely in said slot when the nuts are loosened.

The form illustrated in Figs. l and 5 differs from the first form only in that the recesses 11 in the body of the tie are made longer so as to provide for a plurality of springs, four in the present instance, in each recess, and plates 17 are made longer so as to provide a bearing for the rail upon all of the springs. In this form I have shown the recess 14 which receives the springs as provided With a surrounding Wall or rib which is raised above the surface of the body of the tie, the purpose of which is to give addi tional protection for the upper ends of the springs Without increasing the thickness of the body of the tie, the Wall or rib serving as a guard in preventing the entrance of dust into the recess. The bolts 19 in this form pass through the tivo inner springs but Without contact therewith. In use` the springs are made strong enough to take up the entire weighty of passing locomotives and trains Without permitting plates 17 to come in contact with the bodies of the ties, so that there is a constantly yielding resistance to the Weight of trains, Which reduces y with.

I'laving thus described my invention I claim:

l. A railroad tie comprising a body molded from concrete and provided with longitudinal supporting rods. recesses extending down to the sul'i'porting rods, springs in said recesses which rest upon the concrete and the supporting rods and rail carrying plates which rest upon the springs.

railroad tie comprising a body molded from concrete and provided with recesses. springs in said recesses. carrying plates which rest upon the springs1 clamp-- ing plates for rails and bolts extending through the clamping plates, the carrying plates and the body by which rails are secured to the carrying plates and the carrying plates are retained againsty displacement.

A railroad tie comprisingr a body molded from concrete and provided vvith recesses, springs in said recesses, carrying plates which rest upon the springs, clamping plates for rails, bolts extending upward through the body. the arrying plates and the clamping plates. for the purpose set forthl` nuts on said bolts and spring washers between the nuts and the clamping plates.

Ll. A railroad tie comprising a body molded from concreto and provided with reeesses, springs iu said recesses. rail carrying` plates resting upon the springs and a guard rail plate secured to the carrying plates.

5. A railroad tie comprising a body molded from concrete and provided with recesses, springs in said recesses, rail carrying plates resting upon the springs, a guard rail plate secured to the carrying plates and clamping plates and bolts by which rails are secured to the carrying plates and guard rails are secured to the guard rail plate.

6. A railroad tie comprising a body molded from concrete and provided with recesses, springs in said recesses, carrying plates resting on the springs, a guard rail plate resting on the carrying plates, clamping plates for rails and guard rails and bolts by which said parts are secured together and are held against displacement.

7. A railroad tie comprising a body molded from concrete and provided With longitudinal supporting rods, recesses eX- tending down to the supporting rods, springs in said recesses which rest upon the concrete and the supporting rods, rail carrying plates which rest upon the springs, guard rail plates secured to the carrying plates, clamping plates for rails and guard rails and bolts for securing said parts against displacement.

8. A railroad tie comprising a body molded trom concrete and provided with recesses, ribs surrounding said recesses, springs in said recesses which extend above the body and rail carrying plates which rest` on the springs.

In testimony whereof l atlix my signature in presence of two witnesses.
