M ETALLIC RAILWAY-TIE.

SPECIFICATION forming part of Letters Patent No. 723,965, dated March 31, 1903.

Application tiled July 26, 1902.

iro LZ whom it may concern:

Be it known that I, SAMUEL S. Woon, a citizen of the United States, residing at Elgin, inthe county of Kane and State of Illinois, have invented certain new and useful Improvements in Metallic Railway-Ties, of which the following is a specification.

My invention relates to improvements in metallic railway-ties.

The object of my invention is to provide a tie which will positively prevent the rails from spreading and one in which the rail is readily inserted therein and positiveiy locked and cannot be removed without the breaking of some part thereof.

In the accompanying drawings, Figure l is a perspective of one of my rail-ties. Fig. 2 is a transverse sectional view showing the rails locked therein. Fig. 3 is an enlarged side view of the rail-securing wedge. Fig. 4 is an enlarged view of the locking-key. Fig. 5 is an enlarged side view, partly broke away, showing the rail in position. Fig. Gis a transverse horizontal sectional View of the member D, with the rail in place.

Referring now to the drawings, A represents the main body of myimproved metallic tie, which, as clearly shown, is made of two Vmembers and secured together by the transverse bar B, which prevents them from being forced apart, and thus it is almost impossible for the rails to spread. The said main body is preferably formed with a iat base A', which is provided with a downwardly-extending lug a. The flat base A is firmly embedded in the ballast or road-bed, the dow-.- Wardly-extending lug a serving to prevent lateral movement. The said base is provided with the upwardly-rounded stud C, which is provided at its upper end with the enlarged member D, which is provided with the fiat rail-supporting surface D'. The member D is provided with an inwardly extending flange d, which is adapted to engage the outer liange of the base of the ordinary rail. The inner edge of said rail is provided with the transverse tapering rounded opening cl', the lower edge of which extends considerably below the flat rail-supporting surface D and is adapted to receive a corresponding-shaped Wedge E, which I will now proceed to describe. The said Wedge is round and slightly taper- Serial No. 117,181. (No modeL.

ing toward the end E' to prevent it from being driven too fai" in said opening, and thus preventingit from being removed only in one direction. One side of said wedge is provided with the longitudinal rib e, which is adapted to receive the ledge d, formed from the opening d', and thus forming a Hush joint. The opposite side of the wedge is also provided with a longitudinal rib c, which is adapted to engage the inner flange of the base of the rail, and thus when the wedge is driven home "the rail is firmly clamped in place.

To prevent the wedge from coming out from the opposite direction, Iprovide theinner side of the wedge adjacent the tapered e'nd with the L-shaped recess or groove F, and adapted to fit within said recess I provide an L-shaped locking-key G, which has its end g slightly longer than the groove. Thus said end g projects beyond the wedge.

The operation of my device is as follows: The rail is tirst placed upon the flat rail-supporting surface and the key is placed within the groove carried by the wedge. The wedges are then driven home, thus firmly clamping the rail in position and holding the same. The end of the locking-key after the wedge is driven home extends beyond the edge of the rail-supporting member and is then turned over thereagainst, and thus the wedge is prevented from having a backward movement and at the same time the taper of the wedge preventing it from having a forward movement.

To remove the Wedge, it is necessar f to cut the turned-over end of the locking-key oil with a cold-chisel or straighten it with a special tool, as may be desired.

Having thus described my invention, what I claim, and desire to secure by Letters Pat:- ent, is-

l. A railroad-tie, comprisinga rail-supporting member, a wedge adapted to hold the rail thereon and having an L-shaped recess and an L-shaped key carried by said recess, and adapted to lock the wedge against movement substantially as described.

2. A railroad-tie, comprising a rail-su p porting member, a transverse tapering opening therein, a wedge adapted to enter the opening and clamp the rail thereon and having an L-shaped recess adjacent the tapered end of said wedge, and an L-shaped locking-key adapted to enter the said recess and to be turned over against the tie after the wedge is driven home, substantially as described.

3. A railroad-tie comprising a rail-supporting member, a transverse rounded tanerirg opening therein, a wedge adapted to yenter ihe opening and clamp the rail thereon, and having an L-shaped recess extending to the taperedend, of said wedge, and an L-shaped lockingkey adapted to enter the said recess and extending beyond the wedge, the end of said key adapted to be turned over against the tie after the wedge is driven home, substantially as described.

4. A railroad-tie comprising a rai1support ing member having a transverse tapering
