RAILROAD CROSS-TIE.

Patented July 2, 1912. Serial No. 690,342.

To all whom it may concern.-

Be it known that I, GEORGE G. MCMURTRY, a resident of the borough of Manhattan, city, county, and State of New York, have invented certain new and useful Improvements in Railroad Cross-Ties, of which the following is a specification.

, This invention aims to provide a cross tie of steel or other suitable metal which can be made economically and which has certain advantages in connection with the holding of the rail.

The accompanying drawings illustrate an embodiment of the invention.

Figure 1 is a side elevation of a tie with a pair of rails thereon; Fig. 2 is an end elevation of a pair of ties embedded in the ballast and carrying a rail; Fig. 3 is a cross section of the tie at a point between the rails, on the line 3 3 Fig. 1.

Referring now to the embodiments of the invention illustrated, the cross tie is approximately I-shaped in cross section having a broad flat head A, a vertical web B and a base C which is similar to the head but broader. At each end a suitable length of the head A is bent back to form a shouldered portion D which, either by direct engagement or through the intermediation of a block (Fig. 3), provides a lateral support for the outer flange of the base of the rail F. Preferably the portion D is extended beyond the shoulder G so as to provide an overlapping portion H for holdin down the flange of the rail or the filling block as the case may be. Preferably also a portion of the web 13 is bent over to form a rib J on the portion D so as to stiffen the latter, and the portion D is fastened to the head A of the tie by means of rivets K or by welding 01' other suitable method. The portion D being bent over for a length determined in accordance with the gage of the track and the size of the rail to be used, it is only necessary to force the rail outward against the shoulder and then to bolt in place a clip L holdin the opposite flange of the rail and fastene by bolts M passing through the head of the tie; or where the filling blocks are to be used they may be set in place before the application ofthe rail and the clips L or they may be driven in like wedges after the clip L and the rail are set in lace.

A most economical distribution of metal may be secured by beveling the ends of the tie as at N so as to make the bottom longer than the top. It is desirable to have the tie extend for a considerable distance beyond the rail as shown in Fig. 1.

The ends of the base C are bent down to form a transversedouble flan e P which enters the ballast or the earth be ow the ballast R and forms a wide anchor tending to prevent the shifting of the ties in the direction of their length. This flange is also provided with a stiffening rib Q formed b bending back a portion of the web B with the base.

The shape of the tie is one which can be conveniently and chea ly rolled. The cutting and bending of t e ends can be done cold, using steel of a composition which is entirely suitable for cross ties, and the riveting may also be done cold. The improved tie, therefore, not only provides a construction which is safe and simple in use, the outward movement of the rail on the tie being absolutely prevented, and the lateral shift of the tie being also prevented; but also can be made very inex ensively both as to cost of manufacture an materials.

\Vhat I claim is:

1. A metal cross-tie with beveled ends making it longer at the bottom than at the top and having an integral shouldered portion adapted to hold the rail against outward movement and formed by bending back the end of the tie and having a transverse flange extending below the bottom of the tie and formed by bending down the end of the tie.

2. A metal cross tie approximately I- shaped in cross-section with beveled ends making its base longer than its head, having an integral shouldered portion adapted to hold the rail against outward movement and formed by bending back the end of said head, and having a transverse flange extending below the bottom of the tie and formed by bending down the end of said base.

3. A metal cross tie approximately I- shaped in cross-section With beveled ends making its base 1011 er than its head, having an integral shou dered portion adapted to hold the rail against outward movement and formed by bending back the end of said head, together with a portion of said Web, and having a transverse flange extending below the bottom of the tie and formed by bending down the end of said base together with a portion of said Web.

In witness WhereoLIhav'e hereunto signed my name in the presence of two subscribing Witnesses.
