Be it known that I, JOHN G. SNYDER, a citizen of the United States, residing at Altoona, in the county of Blair and State of Pennsylvania, have invented new and useful Improvements in Metallic Railway-Ties, of

WhlCh the followin' is a specification.

My invention re ates to improvements in railway ties made of a metal casingformed downwardly and inwardly toward the stem of the T, thereby forming a oasin and having a central support. brought toward the stem above the foot of the T or below. The material used for constructing this railway tiemay be rigid or resilient, but preferably the latter.

The object of my invention is to make a tie which will have the advantages of a wooden tie, but none of the disadvantages. The resiliency, if desired, can be obtained by using a s ring material for making the easing whic by reason of its shape, will-necessaril afford a resilient support.

With this and other objects in view, reference is made to the accompanying drawing, in which Fi re 1 is a plan of'a nailwaytie showing t e openings for retaining the fastening clips in adjusted position. Fi s. 2, 3 and 4 are different modlficationsof t e casing, all of which embody the essential features of my invention. Fig. 5 is a detailed view in section, showin means of securingthe rail 3 to the casing. ig. 6 is an enlarged view of one .of the clips which holds the rail in place. Fig. 7 is a section ofthe tie showing the filling.

Similar letters of reference are used on similar parts throughout the sever'alviews.

The tie is made preferably from a T beam having elongated arms which are turned downwardly and inwardly as shown at D.

Fig. 2 and D Fig. 3 and D Fig. 4. The stem ofthe T B is preferably located in the center, but may be on either side of the same or at an an 1e to the generalextent of the casing. The foot of the T C may 1 be above or below the ends D, and the bend in the sides D may beof any shape desired. The ends of the sides D may abut against the stem of the T T or they may be free. The base of the "u G may be smooth or it may have a ortion turned down to get a firmer grip 1n the ballast.

i Specification of Letters Patent, Application filed July- 6, 1,909. Serial No. 506,210.

by turning the longer ends of a T beam The en s may be slot g and slide lnto the sides beyond Patented Nov. 9, 1909.

Such projections are shown at a w 3. ,The he has slots g g commun1cati n w1th the slot l2. formed on o p'osite si es of the rail seat so that a clip F can be fastened in place by means of the bolt e? passing throughthe oasing'and a slot 12 in theclip. The downward turned flange a of the clip E is adapted to engage the shoulders of the slots g g By placin the clip in different slots g g the gage o the track can be changed as may be needed by reason of wear on the inner portion of the rail. The bolt is preferably formed with the flattened shank or some other means for preventin rotation, and the head of the boltis aapted to pass through the large small slot k After the clip is put in position and a washer placed over the bolt, the nut is screwed own securely thereby holding the clip and rail absolutely in place.

In Fig. 3 the arms of the T are curved more sharply than in Fig. 2, and are brought directly down to the base of the T. This forms inclined sides which run directly to the base of the T, thereby facilitating the tamping of theballast around the tieand giving it a good bed for sup ort.

Fig. 4 shows a form of he in which the central support is entirely inclosed within the casing formed by the downward turned arms of the T. This is intended to give -the necessary elasticity to the tie and the central support will limit the movement allowed, thereby giving it the necessary elasticity and at the same time the strength to resist heavy loads, and also to avoidany springing of the the 'co-eflicient of elasticity. This form also has the additional advantage of not having an obstruction at the bottom which might interfere with the tamping of the ballast around the tie. The lower edges of the casing may be roughened in any manner to avoid slipping through the ballast. While the casing is, preferably open when ever it is of advantage, I provide a resilient filling for the same.

With this and other objects in view, I claim as follows z 1. A metallic railway tie consisting of a casing having downwardly and inwardly turned sides and a tral thereof, extending downward from the top in a'longitudinal direction, and means to secure a rail to the casin support substantially cenbeam downwardly and inwar 2. A metallic railway tie formed by turning the longer ends of a T beam downwardly and inwa-r 1y toward the web of the beam, and means to secure a rail to said tie;

' 3. A metallic railway tie formed by turning the lon er ends of a T beam downwardly and inwar ly toward the web, means to secure a rail to said-tie, and a filling for said tie. I

4. The combination of a metallic railway tie formed by turning the long'fir ends of a T y toward the for olding the rail in place', e tie for holding the clip 1n adweb, 'a eli means m t justed position, and mean s for securing the clip to the casing.

5. A metallic railway tie formed by turning the longer ends of a T beam downwardly and inwardly toward the web of the beam, slots with rojections therein cut in said tie, a clip for 'oldin the rail in place having a downward-turne flange adapted to engage the projections in said slots, and means for securing the clip to the tie.
