REINFORCED-CONCRETE RAILWAY CROSS-TIE.

Specification of Letters Patent. Patented June 14, 1910.

Application filed March 11, 1910. Serial No. 548,689.

To all whom it may concern:

Be it known that I, LAFAYETTE J. JACK- soN, a citizen of the United States, residing at East St. Louis, in the State of Illinois, have invented certain new and useful Improvements in Reinforced-Concrete Railway Cross-Ties, of which the following is a specification.

This invention comprehends certain new and useful improvements in reinforced concrete railroad ties and the invention has for its primary object a simple, durable and efficient construction of tie which embodies a novel and useful construction and arrangement of rail supports that are formed by wooden blocks embedded in the concrete tie and preferably resting with their lowermost faces on the reinforcing bar which forms a component part of the body portion of the tie whereby the rails will rest practically on cushions and the liability of the tie being broken by the wearing of the rails will be precluded.

With these and other objects in vie vii as will more fully appear as the dcscription proceeds, the invention consists in certain constructions, arran ements andcombinaifzicins ofthe parts that I shall hereinafter ly describe and claim. 1

For a full understandin ofthe invention T reference is to be had to the following description and accompanying drawings in which: v 3

Figure 1 is a perspective view of a cross tie embodying the improvements of my invention. Fig. 2 is a longitudinal sectional View thereof; Fig. 3 is a top plan View of one of the wooden blocks employed 5 Fig. 4 is a diagonal sectional view of said block; and, Fig. 5 is a perspective view of a portion of the reinforcing bar.

, Corresponding and like parts are referred to in the following description and indicated in all the views of the accompanying drawings by the same reference characters.

My improved cross tie embodies a concrete body portion 1 in which is embedded a reinforcing bar 2 preferably composed of soft steel and preferably located nearer the bottom of the tie than the top, said bar 2 extending substantially throughout the length of the tie but stopping short of the ends thereof, and the ends of the bar being split, the split ends being turned upwardly and downwardly as indicated at 3 to assist in the reinforcing action. Preferably the bar "above the upper ed e of the b as clearly illustrate in Fi 2. 4 i In the preferred metho of manufacture,

2 is located at some distance from the side one-half the width of the body portion, as

' clearly indicated in Fig. 1.

The body portion l.of the tie has embedded therein near the ends, wooden blocks 4 that arepreferably the same width as the reinforcing bar 2, the said. blocks 4 preferably rest-ing directly upon the reinforcing bar, and being secured thereto, each by a countersunk bolt 5, the threaded end of which is located in an opening 6 formed in the body portion 1 below the bar 2 whereby the nut 7 v may be easily screwed on the bolt and readily removed, whenever desired, whereby the blocks may be removed when worn and replaced. Preferably the upper edges of the blocks 4 are sli htly raised y portion 1 the wooden blocks. 4 are first drilled to provide the hole for the bolt 5, said hole being so located that it will lie directly along the rail after =-the latter has been secured in place, and the blocks are initially formed with preferably round spike ho es 8 arranged in ofiset relation to each other as 4 shown, and 'desi spikes which are 0 somewhat larger diameter so as to produce a rigid fastening. After the blocks have thus been formed, they are soaked in creosote to preserve them.

From the foregoing description in connection'with the accompanying drawings, the operation of my im roved reinforcing concreth railway ti'e'wi be a parent,

In forming the ties, tieblocks 4 are drilled to produce the bplt and spike holes and are then soaked in creosote. They are then placed on the reinforcing bar and the concrete body portion 1 is then molded, the

ed to receive square bar being embodied therein. The blocks are secured firmly in place the bolts 5 which extend through the apertures formed in the reinforcing bar, nuts 7 being secured on the bolts in the openings 6, whereby to tightly bind the blocks to the bar. The rails then set in place and spikes are driven into the holes 8 whereby to securely fasten the rails to the cushioning blocks 5. No espe cially designed fastenmgdevices are necessary with my construction and arrangement of parts; as the wooden blocks rest directly upon the bar 2 but do not overlie the side e ges thereof, it is obvious that the wear of therails on the blocks will not injuriously afi'ect the concrete body portion. 1, as it would were the blocks to rest on the concrete, or were the rails to rest directly upon the concrete. Obviously the ties can be cheapl manufactured, and the blocks may be easi y secured in place and removed when worn or when for any other reason, it is necessary to replace them.

Having thus described the invention, what is claimed as new is: v

1. The herein described tie comprisin a concrete body portion, a reinforcing ar mo nted therein, rail supporting blocks e111- bedded in said body portion and resting directly u on the reinforcing bar, the reinforcin ar being of a width equal to the Width 0 the blocks, the body portion being formed below the blocks and underneath the reinforcing bar with bottom openings leading to the lower face of the bar, bolts extending through the respective blocks and through the bar into said bottom openings,

and nuts located in said bottom openings and screwing on the, bolts whereby to bind the blocks to the bags/#1 2. Alrailroad tie, comprising a concrete body portion, a reinforcing bar embedded therein, and extending throughout the length thereof'but stopping short of the ends of the concrete body portion, the ends of the bar being split'and turned in opposite directions, for the purpose specified, wooden blocks embedded inthe concrete body portion, bolts extending throu h said blocks, and reinforcing bar, the body portion being formed withbottom openings in which the lower ends of the bolts are countersunk, and nuts working on the lower ends of the bolts substantially as described. In testimony whereof I atfix my signatnre'in presence of two witnesses.
