To all whom itmay concern."

Be it known that we, AULsoN S. BoUoH ARD, a citizen of the United States, residing at St. Louis,.in the State of Missouri, and JOHN ALLAN WILKINSON, a subject of the King of Great Britain, residing at NewYorlk, in'the' county and State of New York, have invented certain new and useful Improvementsin Metallic Railway-Ties; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same The ob ect of our invention is to produce a metallic railway tie of satisfactory construction which may be cheaply made and easily placed and which furthermore provides ad'-' justing means for taking up the wear between the railroad rail and the arts of the tie which engage the rail to hofd it in place.

The nature of'our im rovements will be understood from the f0 lowing description and the accompanying drawings, in which the samereference characters indicate like parts throughout.

In the accompanying drawings, Figures 1 and 2 represent, in side elevation and plan one form or modification of our invention; Figs. 3, 4 and 5 represent sectional views thereof on the lines 33, -i4 and 5-5 of Fig. 1; Figs. 6 and 7 represent, in side elevation and plan, another form orlmodification of the invention; Fig. 8 represents a perspective view of a detail thereof; Figs. 9 and 10 represent, in side elevation and lan, another modification, and Figs. 11 an 12 rep-- resent a side elevation and .a sectional view of a still further modification.

The body of the tie is composed of a rolled T-bearn a and it is intended that the flat surface of the beam shall be placed on the road bed. For the purpose of increasing the grip of the tie on'the road bed, we prefer to rivet or weld, or otherwise secure to the under surface thereof, the transverse strips 1). To the upstanding flange of the T-beam we secure the saddle blocks 0 adapted to engage the foot of the road rail and preferably engaging also the web and acting as a support for the head. These saddle blocks are preferably formed of rolled, forged or malleable metal bent to the inverted U-shape shown in Fig. 3 and adapted to slide along the upstanding flange of theT-beam.

The upper edge of the upstanding flange will not ordinarily aflord a sufliciently extended bearing surface for the rail. To provide such a bearing surface we adopt the construction shown, in which We attach to each side of the upstanding flange a metallic, box-like construction (1 formed in the desired shape. Into the chamber formed by this box-like construction on each side of the flange we insert a wooden-block e which rises to a level with or slightly above the edge of the box (1. The bolts which secure the saddl e blocks to the flange also secure these boxes at thereto.

For the urpose of taking up the wear of the faces 0 the saddle blocks which engage the road rail, we provide means for adjusting j the saddle blocks toward the rail. It is or-g dinarily suflicient to a ly such adjustingj means to the outside saddle blocks alone, butl where it is advisable to do so, it may be a lied both to the inside and outside sad e locks. One form of this adjusting mech anism is shown in Figs. 1 to 5 in which the bolts m secure the saddle blocks to the upstanding flan'ge of the tie through elongated slots. Above these securing bolts is a wedge bolt f which asses through elongated slots in the saddle fllock and in the ortions of the boxes d which extend along t e flange. In the body of the flange there is an elongated slot g which is staggered with relation to the slots in the saddle block, as shown most clearly in Fig. 5, whereby a tightening up of the wedge bolt f forces the saddle blocks toward the rail, thereby taking u the wear.

In Figs. 6, 7 and 8 we have s own a modilied construction of the boxes (1 by which the inner saddle block may be dispensed with.

To this end these modified boxes (1 (see Fig.

8) are provided with turn over flanges (Z engaging the foot of the rail and, if desired, extending up the web to engage the under surface of the head.

In Figs. 9 and 10, we have shown a modified means for adjusting the saddle blocks toward the road rail, in which the saddle blocks a have flanges n extending along the sides of the boxes d and. bolts 0 extend through the lateral flanges n on onesaddleblock, the box (1, the block 6 and the lateral flanges n on the other saddle block. By tightening these bolts 0 the saddle blocks are drawn toward the rail.

In Figs. 11 and 12 we have shown a modi- T-beam so that the .fied construction of bearing block Which comprises a member having a flat surface 1' and inwardly bent depending flanges r which engage the u standing flange of the at surface 1" overlies the upper edge of the flange. This surface r is preferably providedwith ridges 1 along its edges and in the space between these ridges is placed a wooden cushioning block W on which the road rail rests. These bearing blocks are secured to the flange of the T- beam by the bolts 8.

What We claim is v 1'. In a metallic railway tie, a body portion formed of a T-beain extending across the road bed, saddle blocks straddling the upstanding flange of the T-beam in position to engage the road rail, and means for adjusting the saddle blocks toward the road rail comprising a wedge bolt which engages staggered slots in the upstanding flange and in as described.

tion formed of a T-beam extending across the road bed, an elongated bearing surface for the road rail formed by a box-like structure secured at each side of the upstanding flange of the T-beam, a holding member secured to the said. flange to engage the outside of the road rail and a second holding member engaging the inside of the road rail and proj ecting from and formed integral with the inner side of the box structure; substantially as described.
