SPECIFICATION forming part of Letters Patent N o. 683,531, dated October 1, 1901.

Application filed .Inly 25, 1901.

To all whom, it may concern.'

Beit known that I, WILLIAM VADE, a citizen of the United States of America, residing at Trenton, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Railway Ties, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to a composite railway-tie in which the advantage of an elastic wood seat is combined with that of a metallic tie of maximum strength and minimum amount of metal and of such simple construction that it may be easily rolled and serve as a retainer for the wood cushion, in connection with a simple and strong track-fastening which connects the rails directly With the tie and permits the changing or renewal of the wood cushion independently of the tie or track-fastening, all as more fully hereinafter described, and shown in the accompanying drawings, in which- Figure lis a perspective view of my improved tie with one of the track-rails secured in place upon the tie. Fig. 2 is an end elevation of the tie. Fig. 3 is a cross-section of the metal portion of the tie on line 3 3 in Fig. l. Fig. 4 is a vertical longitudinal section through the outer end of the tie substantially on line 4C 4, Fig. l.v Fig. 5 is a detached perspective view of a portion of metal tie and of the two rail-hooks cooperating therewith, the tie being of slightly-modified construction.

A designates a metal tie, formed with a bottom a and two sides b, making it U-shaped throughout its entire length, which is that of the common Wooden tie and adapted to be formed by rolling, like other structural iron.

B designates the rails of the track.

C designates clam ping-dogs for securing the rail to the tie,and D designates wooden blocks secured in the end of the tie and forming the support and cushion for the rails. The clamping-dogs are iiat metal strips or bars, each formed integrally 0n edge with an upwardlyprojecting hookf, adapted to embrace the foot Serial No. 69,609. (No model.)

the sides of the tie for the purpose of anchoring the dogs to the tie. The Wooden blocks are of a width to hold the dogs in position against the sides of the tie when driven into the end of the tie and of a height to hold the rail out of contact with the metallic portions of the tie, thereby forming a cushion for the rail and at the same time a locking key or wedge which secures the clamping-dogs in pairs in the ends of the ties. To facilitate the driving in of these blocks, they may be made slightly Wedge-shaped or merely beveled oif at the inner ends, either on top alone or on the sides as Well. To prevent the dogs from becoming loose in case of shrinkage of the wooden blocks, the dogs are curved, as shown, so that they form a strong spring, which will be flattened out against the sides of the tie when the blocksD are driven in. I also preferably make the anchoring-hooks esufticiently long to project well through the openings g, so that they could not possibly draw out of engagement therewitli,and might even permit of their being bent over to clench on the outside. To provide for contingencies which might make it desirable, I also provide one or more holes h in each end of the tie for driving a nail through into the wooden block to hold it in place. Another provision of ,which I might desire to avail myself in case the wooden blocks are of reasonably soft wood is .to make the bottom of the tie corrugated, as

shown in Fig. 5, so that the wood will press vinto the corrugations, and thereby become able amount of elasticity and thorough cush- IOC detachably secured against vertical and longitudinal displacement on the inner faces of the sides of the tie, two on each end upon the opposite sides of the tie, and wooden blocks in the ends of the tie operating as a key or wedge to lock said bars in position in the tie against lateral displacement, said bars formed with a hook to engage the foot of the rails.

2. In a rail-fastening, the combination with a metallic U-shaped tie, of flat metal bars detachably secured against vertical and 1ongitudinal displacement upon the inner faces of the sides of the tie, two in each end upon opposite sides of the tie, and wooden blocks driven into the ends of the tie operating as a combined wedge or key to lock said bars in position in the tie against lateral displacement and as a bearing to support and cushion the rails, said bars having hooks projecting above the wooden blocks and adapted to engage the foot of the rails andclamp it to the tie.

3. In a rail-fastening, the combination with a metallic U-shaped tie, of flat metal bars curved in their horizontal planes to form springs and detachably secured against vertical and longitudinal displacement on the inner faces of the sides of the tie, two in each end upon the opposite sides of the tie, and wooden blocks in the ends of the ties between each pair of bars operating as a key or wedge to hold said bars in position in the tie against lateral displacement, said bars formed with hooks to engage the foot of the rails.

4.- In a rail-fastening, the combination with a metallic U-shaped tie, of flat metal bars supported in the ends of the tie in contact with the sides thereof and of corresponding height therewith, anchoring hooks or projections formed at the ends of said bars, holes in the sides of the tie into which said anchoringhooks engage, a hook integrally formed on the upper edge of each bar and adapted to engage the foot of the rail, the hook of one bar on the outside and the hook of the other in the corresponding end of the tie on the outside, and Wooden blocks driven into the ends of the tie and operating as a key or wedge between the under sides of the rail and the bottom of the tie and between the metal bars in the ends of the tie.

5. In a rail-fastening, the combination with a metallic U-snaped tie, -of dat metal bars supported in the ends of the tie against the inner faces of the sides of the tie, two ineach end, each bar provided with a hook for clamping the foot of the rail, one upon the outside and one upon the inside, interlocking means onsaid bars and the sides of the tie to prevent longitudinal and vertical displacement of said bars, wooden blocks driven into the ends of the ties and operating as a key or wedge between the under side of the rail and the bottom of the tie and between the metal bars in the ends of the tie, and means on the ends of the tie to prevent accidental displacement of the wooden blocks in said ties.

In4 testimony whereof I aiiix my signature in presence of two witnesses.

VILLIAM WADE.
