LEWVIS BARNES, OF BELVIDERE, NElV JERSEY, ASSIGN OR OF THREE-FOURTI-IS TO WILLIAM C. ALBERTSON, GEORGE M. SHIPMAN, AND KERR F. ALBERT- SON, ALL OF SAME PLACE.-

RAI LROAD -TI E.

SPECIFICATION forming part of Letters Patent No. 423,852, dated March 18, 1890.

Application filed April 22, 1889. Serial No. 308,177. (No model.)

To all whom it may concern: Be it known that I, LEWIS BARNES, a citizen of the United States, residing at Belvidere, WVarren county,'New Jersey, have invented certain new and useful Improvements in Railroad-Ties, of which the following is a specification.

This invention relates to that class of railroad-ties known as l116ttlllC'lJl6S; and it IO consists in a tie adapted to sustain and firmly hold in place a longitudinal or longitudinallyarranged sill-plate preferably of wood, and to which the rail is spiked, as distinguished from a metallic cross-tie directly sustaining the rail.

In the accompanying drawings, Figure 1 is a perspective view of the improved tie, illustrating by dotted lines a longitudinal sillplate supposed to extend from tie to tie, and also a longitudinally-arranged sill-plate of a length approximating the width of the tie. Fig. 2 is an elevation of the same, the sillplates being in position and the rails secured thereto. Fig. 3 is a modification of the inner flanges, showing them formed of one piece of metal. Fig.4 illustrates different shapes of the tie in cross-section.

The improved tie A consists, essentially, of a main plate 10, exterior flanges 12, and inner 3o flanges 13. Between each pair of flanges is supported a longitudinal or longitudinallyarranged stringer or sill-plate B, secured and firmly held in place on the tie by bolts or spikes passing through the flanges. Each end of the main plate 10 is bent or doubled upon itself for a short distance, as at 14, and the end of this doubled-over portion is bent at right angles to itself to form the flange 12. This mode of providing the exterior flanges 12 integral with the main plate is to be preferred, as it imparts a certain elasticity. to the stringer or sill-plate and. lessens the shock to the passing train. The inner flanges 13, as shown in Figs. 1 and 2, are each a right-angular bent plate bolted or otherwise secured to the main plate a proper distance from the exterior flan ge to permit the stringer or sill plate to rest upon the main plate between said flanges. Instead, however, of forming the interior flanges 13 of separate pieces, they may be formed of a single plate 0, as in Fig. 3, the flanges 13 being formed by bending its ends up at right angles, which plate 0 will be bolted or otherwise secured upon the main plate 10 of the tie in position to leave a space between each pair of flanges for the stringer or sill-plate. The tie may be of any desirable form in cross-section. Thus it may be of flat metal, as in Figs. 1 and 2; or it may be flanged or curved, as in Fig. 4. It might also be corru- 6o gated or oval or other shapes, as may be thought desirable.

The preferred form of longitudinal stringer or sill-plate B is a continuous one, extending from tie to tie the length of the railroad; but where timber is scarce and expensive short sill-plates, as illustrated at the right hand of Fig. 1, will be employed.

In practice the metallic tieA will be embedded in the road-bed with the ballasting 7o material properly packed around .it, thus forming substantially a permanent cross-tie, which need not be removed or disturbed in fixing the road-bed.

The stringers or sill-plates being of wood 7; may, when occasion requires,be removed and changed for others without disturbing the cross-ties or the road-bed.

That I claim is- The combination, with a metallic tie hav- 8o ing its exterior flanges formed by the doubledover ends of the tie, and inner flanges secured thereto, of a longitudinal stringer or a sill-plate for the rail, supported upon the tie between each pair of flanges and bolted thereto, substantially as described.

In testimony whereof I have signed my name to thisspecification in the presence of two subscribing witnesses.

LEWVIS BARNES.
