No. 905,234. Specification of Application filed August 16, 1907. Serial No. 388,884.

To all whom it may concern:

Be it known that I, OscAR ROWLE'IT, a citizen of the United States, residing at Maysville, in the county of. Dekalb and State of Missouri, have invented a new and useful Railroad-Tie, of which the following is a specification. I a

This invention relates to metal ties for rails, more particularly on bridges, although they can as readily be employed on the ground as are wooden ties.

The object of the invention is to cast, roll or otherwise. construct metal railroad ties,

each having a central vertical web and a top and bottom horizontal flange, said ties having about the same dimensions as ordinary Wooden ties. f

To the ties are secured the railroad rails by novel connections, and the ties are in turn connected together by long bolts or rodspassing through spacing pieces which regulate the distance between ties.-

A further object of the invention is directed to the manner of fastening the ties to the bridge beams so that, while holding tightly thereto, they may be quickly released therefrom and from the rails. and a new tie as easily substituted.

In the accompanying drawing :-Figure l is a horizontal cross section ofa railroad track between two ties, showing the means used for fastening a tiete thebridge beams. Fig. 2 is a plan view of 'a portion of a track I including three ties. 3 is a crosssection on line 3-3 of Fig. 2. i

Smnla i; reference numerals are used f e the same parts in all the figures.

The drawing llll istrates the invention in use on a bridge wherein a small portion, is shown such as two. longitudinal I beams 1 and a tie beam 2 connecting them. The railroad ties 3 are placed across the bridge beams'l and project beyond them equally at each end. .Each tie 3 is forged, rolled or'" cast in the shape of an I.bea-m, the upper and lower flanges lying in horizontal planes connected by a central vertical web 4 shorter at each end than the fianges'and smnewhat" thicker than is found in commercial beams of like shape. Each tie 3 is fastened to the bridge beams 1 by means of L shaped lock bolts 5 which pass at each end :yertically through the upper and lower fianges' on one or both sides of thelweb 4 close'to,,the top Letters Patent.

flanges of the bridge. beams l on their outer sides. The extended portions 6 ofi'theJock place by nuts 7 on the upper end of tlfe lock bolts, screwed hard against the ties In the longitudinal center of each tie is formed a series of spaced vertical apertures "8 in which are placed hook-shaped pins- 9 wherever needed to hold railroad rails 10 in place. The hook-shaped pins 9' are held firmly in position by means of bolts or rivets 11 extending through holes 12 in the webs 4 and registering holes 13 in the pins 9. The sides of the pins 9 which enter the apertures 8, are preferably rectangular, the head of each having a projecting finger 14 which enfish plate and by means of the connection, heretofore described, the rails are held .securelyfastened to the ties. Where an addition of straight rail forming a part of a turnout, for instance, lies close to the main rail, a pin 15 is used having a projecting finger 14 on each side of its head to engage both rails, see Fig. 1.

The ties are prevented from slipping or creeping on the beams by means of longbolts or rods 16 of varying lengths, some of which may extend from tie to tie only, while others theirflength. The bolts or rods 16" pass through the webs of the ties near their ends and throughspacing block or tubes 17 against the ends of which the ties abut.

equaldistances apart, but on a curved track, the outer blocks ,would be longer as understood, Below the rail seats of the main tracli/ mfon the ties 3 are cross webs or :flan'ge' .18, each web extending vertically frdi'h flange toflange and horizontally from the 'web 4120 the outer limit of theflanges. These cross webs 18 are wider at the top than the bottom,- and are intended to give a firmer support to-.-t-he=-rails., .As heretofore stated the webs are shorter at each end than the upper and-lower flan es thus. leaving a space within each end of the tie. space may be occupied by electric wires, cables, switch rods, pipes and other artiti-lessuitable td'be placediherein. 'lhrongh' the upper bolts are placed under the upper flange the, bridge beams and fastened rigidly in may include an indefinite number of ties in These spacing blocks are of equal length on a straight. track thus keeping-the ties at gages over the bottom flange of the rail or g tional rail, as a switch rail, or a short secand lower flanges are holes 30 for use when the read using these ties is equipped with the block system of signaling.
