Application filed September 13, 1910. Serial-No 581,868.

Patented Nov. 22, 191i To all whom it may concern.

Be it known that I, RICHARD J. D. (Iowan, a citizen of the United States, and a resident of Greenville, in the county of Wayne and State of Missouri, have invented certain new and useful lmyno'w-unents in Concrete Railway-Ties, of which the following is a specification.

This invention is an improvement in railway ties and particularly in such ties of concrete construction; and the invention consists' in certain novel constructions and combinations of parts as Will be hereinafter described and claimed. In the drawing Figure 1 is a perspective view of a tie embodying my invention. Fig. 2 is a horizontal sectional View of one of the end sections of the tie on about line 2 2 of l Fig, 3 is a cross section on about lin' -33 ofldig. 1. I

tie as shown, is composed of three ins, an intermediate section A and the ions a description cl one will answer for d the several sections A and B are rcinforiiced by longitudinal rods C as best shmvn in l. u. and 3 said. rods C extend ing in the direction of length of the sections Ti o horizon l lines and bein provided at n or eyes G through cross rods or bolts l) which :re the y lies The cross o the intermediate section A. v the tie rods F which resecured at one cut to the bolts A and at their other ends to the bolts D at the inner ends of the endgsections B. this consl: action t to tie sections of concrete are .reiniorced-longitudinally and the reinforcing means cooperate in providing strong connections between the central and end sections or the tie Will be understood from the ope-rate to rods or bolt clamps or yolres E have their arms secured by the bolts of the end sections and their on s bars extend over the rail. seats Gr and H as shown. These rail seats may each be formed of a single block as shown at G in 1 or they may formed a series of ".lhesc ends-actions B are layers as shown. at H in Fig. 1, and the block may beof Wood or other suitable material and the'layers H may be of Wood paper or other suitable material and this sectional construction as shown at H enables me to vary the sections employed in order to secure the desired height of rail as may be necessary in any particular case.

In supporting the rail seats G or H, I provide in theupper faces of the sections B recesses I from which subrecesscs J extend at a point directly below the rails K, thus increasing the resilience of therail seat. The recess I prevents any longitudinal displace ment of the rail seats and the yokcs or clamps E secure the rail seats firmly in their re- 7 cesses.

the rails, bolts L may be employed to secure rail clamps or blocks M which overlap the rail base as shown.

By constructing the tie in three sections and uniting the intermediate section with the end ones by the loose flexible joints secured through the aid of the coupling-rods F, I furnish a novel construction of tie and the clamps or yolrcs for securing the cushioning rail seats permit of the cushions be mg for brating tion of the rolling stock. It Will he noticed that the reinforcing rods or plates are embedded in the concrete with no parts exposed thereby prolonging materially the life of the tie.

I claim:

1. A tie substantially as described, composed of a central section and and sections consisting of concrete, reinforcing rods therein having eyes at their ends, cross bolts extending through the said eyes, rods-coi'inecting the cross bolts of the central section with the adjacent cross bolts of the opposite end sections, the end sections being provided in their upper faces with recesses and with sub-recesses intermediate the ends thereof to underlie a rail cushioning rail seats in the recesses of the said end sections and clamps securing said rail seats and haw ing their end arms secured by the cross bolts of their respective sections, substantially as and for the purposes set forth,

2. A tie composed of an intermediate section, end sections on opposite sides of the intermediate section, coupling rods connect- In securing coupling titted loosely therein thereby providing expansion rail. and allowing the v1 motion desirable tor the n'eselmiing the end and intermediate sections, cushioning railseats on the end sections, and

' provided'at their ends with eyesand cross bolts passing through the eyes of said reinforcing rods, of clamps having endarms secured by said cross rods and a cross bar extending from side to side above the tie and a cushioning rail seat secured by said clamps,

' 3 Vvltnesses:

substantially as set forth. I H

4, The combination of a concrete tie composed of an intermediate section and end i sections having longitudinal reinforcing rods provided with end eyes, bolts extending through said eyes and projecting beyond the tie sections, coupling rods connecting the adjacentbolts of the end and intermediate sections whereby to secure the intermediate and end sections in connection, rail seats on the end sections and yokes securing said rail seats and held by the cross bolts of their respective tie sections, substantially as set forth. v I
