STRUT-TI'E l-'OR PREVENTING CREEPING OF RAILS.

SPECIFICATION forming part of Letters Patent No. 611,101, dated September 20, 189.8.

Application iiled May l0, 1898. Serial No. 680,309. (No model.)

To all whom, t may concern,.-

Be it known that I, ADoLPHUs BoNzANo, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented a certain Improved Strut-Tie for Preventing the Creeping of Rails, of which the following is a speciiication.

The object of my invention is to prevent the longitudinal creeping of railway -rails upon the ties caused by the passage of trains thereover. This object I attain by providing a device which is secured to the rails and to the ties in a manner fully described hereinafter, reference being had to the accompanying drawings, in Which- Figure 1 is a perspective view of my improved device for preventing Ithe creeping of 2 is a side view showing the device in position. Fig. 3 is a plan view with the rail in section. Fig. 4 is a View of a modification, and Fig. 5 is a view of a modified form of strut-tie.

Rails of railway-tracks are solaid that they are free to expand and contract, and consequently are also free to creep, which is a longitudinal movement caused by the rollingstock passing over them. While the rail must be free' to expand and contract, the creeping must b e checked. I accomplish this in the following manner:

A is the rail of a railway-track.

B are the ties, to which the rail A is secured by spikes b. I perforate the web o, of the rail at or about the center of its length and secure` thereto a strut-tie D, which is also secured to the ties.

The strut-tie is made, preferably, in the` form shown in Fig. 1, having a flat central section d, adapted to rest against the web of the rail, and flat end sections d d at right angles thereto and adapted to rest on the ties and connected to the central section d by members d2. The strut-tie is of such alength that the end sections will rest on two ties, as Shown, with an intervening tie under the center where the strut-tie is secured to the rail.

The strut-tie D is secured to the rail by a bolt or rivet c and to the ties by spikes or screws ff.

I prefer to turn a lip d4 on each end of the strut-tie D,Which enter the tie and thus take the strain off of the spikes f and give a wide resisting-surface against longitudinal pressures.

I prefer to make the strut-tie by cutting a metal bar to the proper length and then bending it to shape, as shown in Fig. 1; but other methods of making the device may be employed without departing from my invention.

It will be noticed that when the strut-tie is in position if the rail has a tendency to move longitudinally in one direction one of the members cl2 will hold .it under tension, while the other will hold it under compression. Thus the entire strut-tie is brought into action and there is no tendency to impart lateral motion to the rail, as one member d2 counteracts the other member.

The strut-ties maybe placed one on each side of the rail and bolted together and to the rail, or the strut-tie may be made in two parts, as shown in Fig. 4, one part D on one side of the rail and the other part D2 on the other side of the rail.

fasteningof the strut-tie to the cross-tie B at the points shown does not interfere with the rail-spikes, and the ties will not tip under either torsional or compression strains.

In some instances the strut-tie may be made as shown in Fig. 5, having extended members d3, being of such a length as to rest each upon two ties, and I have shown in this iigure the central portion having two holes for two securing-bolts. It will be understood that the strut-tie may have one or more boltholes and one or more holes for the spikes to secure it to Athe ties and that while I have shown the strut-tie made of a plain bar a flanged or other-shaped bar may be used withi IOO member secured to-a cross-tie, so that each end of thenail is .f1-ee to expandoi" contract, substantially as described.

The combination of a rail, cross-ties on which the rail is mounted, a strut-tie having a central section secured to the web of the rail, end sections-secured to cross-ties and twisted members connecting the end sections to the central section, said strut-tie being of 1o such t length as to extend from one tie to anothei` with a itie intervening, substantially as :described ADOLPHUS BONZANO.
