PATENT FREDERICK VILLMONT DUNNELL, OF SPRINGFIELD, MASSACHUSETTS.

SPEGEFICATION forming' part of Letters Patent No. 683,7 34, dated October l, 1901.

Application filed January 25, 1901. Serial No. 44,689. (No model.\

T0 tu whom, it may concern:

Be it known that I, FREDERICK WILLMoNr DUNNELL, a citizen of the United States, and a resident of Springfield, in the county of Hampden and State of Massachusetts, have invented a new and klin proved Railroad Cross- Tie, of which the following is a full, clear, and exact description.

One object of this invention is to utilize a waste material, such as leather scraps and worn-out foot-gear, in the manufacture of railroad cross-ties, a further object being to provide a cross-tie of leather and metal plates suit-ably constructed which is simple, practical, and efficient in service.

The invention consists in the novel coustruction and combination of parts, as is hereinafter described, and defined in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure l is a plan view ot' the improved cross tie and portions of two track rails mounted thereon. Fig. 2 is a side view of the same. Fig. 3 is an enlarged longitudinal sectional view-substantially on the line 3 3 in Fig. 1, and Fig. 4 is a transverse sectional view substantially on the line 4 4 in Fig. 1.

In carrying into effect the features of invention a suitable number of similar blocks 5 are provided, these consisting of pulped and subsequently consolidated leather. As shown, said blocks each consist of a rectangular slab of proper thickness and area.

In order to utilize waste leather and wornout boots and shoes in the manufacture of the blocks 5, such material is ground into pulp with a suitable liquid to form a plastic mass. This material is then formed into sheets that represent the thickness of the blocks, which are subsequently cut from the sheets into rectangular form, and then they are assembled to form a cross-tie, as follows:

The series of blocks 5 have each a central perforation formed therein, and a bolt 6 is passed therethrough, said bolt having a head o. on one end and a nut b on the threaded opL posite end of the same. The bolt 6 is of a length which conforms with the length of the cross-tie to be formed, and exterior of the blocks 5 at each end of the tie a washer-plate 7 is located on the bolt.

The assembled blocks 5 are arranged so that their edges will be disposed in four planes, that represent respective sides of the cross-tie when it is completed, and the series of tie-blocks are now compressed against each other in sequence by a proper adjustment of the nut b, thereby producing a leather tiebody.

Upon opposite faces of the tie-body, which respectively represent upper and lower sides thereof, two similar metallic plates S 9 are secured by bolts c, 8 being the cap-plate of the cross-tie, and 9 the base-plate thereof. The cap-plate 8 and base-plate 9 have each a plurality of flanges 8 and 9, respectively, formed thereon along their side edges at spaced intervals, and it is to be understood that any preferred number of said iianges may be employed. The width between opposite flanges on the cap-plate 8 and likewise paired flanges to closely bear upon the side walls of the cross-tie body, and thus prevent the material of the body from yieldinglaterally.

Upon the cap-plate S, at a proper' distance from each end thereof, provision is made to retain track-rails A A in place on a plurality of the cross-ties of a railroad. To this end proparly-positioned orifices d are formed in the cap-plate 8 for reception of the ordinary railroad-spikes e, which may be driven into the body of the tie at each side of each trackrail and bear with their hooked heads upon the base-flange of each track-rail in the usual manner.

To reinforce the binding action of the spikes e, two clam ping-plates 10 are provided for each end portion of the cross-tie, said plates having one end portion of each one bent to adapt it to bear upon the head of an adjacent spike c, the remaining part of each clamping-plate, which is seated upon the capplate S, being bolted thereon by screw-bolts, that pass through registering pert'orations in the clamps and cap-plate, as indicated in Figs. 2 and 3.

It is claimed for the improved cross-tie that it is of moderate cost, is very durable, is

`on the base-plate 9 is such as will adapt these IOS su'i'iciently elastic to afford elieient service, and is mainly formed of a Waste product.

Having thus described my invention, I claim as new and desire to secure byLetters Patent- 1. A cross-tie, comprising a leather body, and plates of metal adapted to hold the body consolidated.

2. A crosstie, comprisingaseries of leather blocks held together by a bolt to form a tiebody, and reinforced laterally by plates of metal secured on said body.

3. A cross-tie, comprisinga series of leather blocks held together in sequence by a bolt and Washer-plates thereon.

4. A cross-tie, comprising a series of rectangular leather blocks flat on the sides, said blocks each having a central orifice, a bolt and screw-nut, and Washer-plates placed on the bolt near its ends after the leather blocks are located in sequence on the bolt-bod y, the

leather tie-body being consolidated by an ad` justment of the screw-nut.

5. In a crosstie, the combination with a series of rectangular centrally-perforated tieblocks, Washer-plates at the ends of the cross- FREDERICK WILLMONT DUNNELL.
