To allwhom it may concern: A.

ZAN0, a. citizen of the United States, and a resident ofGoshen, Rockbridl e county, Virginia, have -invented certain mprovements in CompositesRailroad Gross-Ties, of which the followingis a specification. v

The object of my invention is to provide a railroad cross-tie of composite character designed to take advantage ofthe strength and other valuableproperties of metal, andthe iibrous material,

novel manner and producing amost satisthe purpose i described. My invention is fully shown in the accomdrawings, in which: FigureA 1, is a view in elevation oi a commade in .accordance with mly in- Fig. 3, is4 a sectional view, taken onthe line en -a, Fig. v1; Fig. 4, ,is a sectional view,

a further detail of my invention.

In my patent, No. 844,774, dated February 19, 1907, I have described and claimed a metallic cross-tie comprising a channel vas centrally disposed slit, v nel beam or trough section forming the tie, 41s

beam or trough section, the web of which is 4'laid lhorizontally and centrallyT cut, and the metal on opposite sides of said cut. displ aced toward .the side walls of such channel beam. The ends of th'echannel beam are crimped or otherwise closed so that between said ends andthe centrally displaced upper web, ballast holding pockets areV provided.

In the tie forming the subject of my present invention, I propose to use channel beams or trough sections of substantially the saine type Ishown and described in my patent above referred to, having the central portion of the upper web placed towards the side vi/'alla In the present instance, in addition to the the web 1 of the chan.-

cut out at the points 2, adjacent the ends of the same, to receive blocks of wood or other fibrous material 3 upon which the rails rest, and to which the 'rails mdp' be fastened in an approved manner. o blocks, the under spxace inthe channel beam tie at 'the ends of t slit and all or part of l the metal on opposite sides ofthe same dis-- support these e same and directly bel low these blocks 3 contains filling means,

such means in one instance comprising a palr of blocks 4,' and a wedging block 5, as shown in Fig. 3; and in the other instance, a single block 6, as shown in Fig; 5. The blocks 4 lieagainst and approximately parallel with the walls of the channell beam o r trough section, while the block 5 iits lthe space formed between the blocks 4 and keys the latter in place. The blocks by the rail astenings, and' if a series of blocks are used, they will be wedged into the cavity oi the cross-tie by the vertical pres.- sure and reaction 'of the ballast or road-bed, for example. As the blocks within the chanare further held in place4 nel beam tie rest upon the road-bed or baldo not depend at all for their vertical sup-A port upon the'metallic ortion of the tie.

The side walls .of t trou h section forming the. tie are flanged at 8 an are confined against spreading by one or more clamps 9, as clearly shown in Figs. 1,

2 and 3, and the block or blocks mounted 1n.

the ends of such channel beam. or trough section and Vconfined against sidewise displacement by these clam s, which also aid in preserving the shape of tile trough section or shell, may be driven in and out when necessary. The blocks are so made as to rest upon these clamps as far as necessary to hold them in place, and may have undercut portions 1j() between the portions en aging lthe clam s into which the ballast of t e road-bed will e tamped or ind its way and serve as additional means-for retaining the tie in place.

To prevent endwise displacement o the blocks4 and 5 .with respect to `the channel beam or trough section, I provide bolts 11,' passing through the tie. and through the block or blocks, the manner shown in the drawing.- vby a p ate 12, suitably shown in Fig. 6,' as may be most. convenient or desirable, and allow the blocks 4 and 5, or 6, to abut against said closure.

The rails are preferablyjfastened to the blocks 3 and the blocks supporting the same by means of headed lag screws or bolts 13 passing through such rail suptporting blocks and into or through the bloc the same. In some instances, I-may secure Or I may close the end of thetie secured in place, as

e vchannel beam, or

; on opposite sides of said slit l fastening 'between the bed and the displaced the rail supporting blocks 3 to the block or blocks below the same by means of spikes 14, as indicated in the drawing. Other lforms of fastenings may be employed, however, without departing from my invention.

In Fig. 5, I have shown a structure in which a single block 6, confined bythe channel beam or trough section, is ein l'oyed.beneath the iail supporting blocks 3 instead of the series shown in Fig'. carries the fastenings for securing the rails to the blocks 3, such fasteningsbeingin the forni of bolts '15, with or without iail engaging or heads, whichv pass through the rail sup orting block and block 6; and being con ined thereto by nuts 16 which are coun tersunk in such block. The blocks 6 .will also be retained 'against endwise displacement in the tie by the bolts 11 `at the ends oi" the same, or by the closure 12 shown in Fig. 6. If desired, the blocks 6 may be made in two horizontal layers, and the nuts 16 countersunk into either oneV of the contacting faces. These nuts may be tapped to receive one of the bolts, or an elongated nut may be employed tapped to receive two bolts 13 mounted adjacent each other on one side of the rail.

The blocks 3, of wood or other fibrous material, are preferably provided with metallic wear lates 17 for contact with the rail bases.

I c aim: 1. In a composite tie, thecombination of a metal channel beam or trough section, resilient rail-supporting blocks disposed in apertures in the top web of s aid beam and projecting above the same, and blocks confined by .said beam and in contact with the road-bed upon which said rail-supporting blocks are mounted.

2. In a composite tie, the combination' with a metal channel beam or trough section having its top web partly slit and the metal displaced towards the side walls of the saine, said web being apertured adjacent its ends, of' railsupporting blocks disposed in said apertures, and blocks in. contact with the road-bed and confined by said beam upon which said railsupporting blocks ,are mounted, such construction providing ballast holding pockets blocks in contact with the roadportion of' the tcp web.

3. In a vcomposite tie, the conibinatioii with a metal channel beam or trough section having the central portion of its top web slit and the metal on opposite sides of said slit said apertures, and

displaced towards the side walls of' the saine, said web being` apertured adjacent its ends, of resilient rail-supporting blocks disposed in resilient blocks in con tact with the road-bed and confined by said beam upon which said rail-suppdrting blocks are lmounted, such construction providing ballast holding pockets between the blocks in In this instance, the block 6,

4. In a composite tie, the combination with a metal channel beam or trough section 6. In a composite tie, the combination vwith a metal. channel beam apertured adjaf cent yits enr' s, of resilient blocks disposed inf said a ertures and projecting above "the'tie, supp eniental blocks contacting with the road-bed upon which the rail-supporting blocks are mounted, said sup-V plemental blocks being disposed between the walls of the tie, and means for securing the rail-supporting blocks to said supplemental blocks.
