METALLlC TIE.

SPECIFICATION forming part of Letters Patent No. 746,742, dated December 15, 1903. Application filed May 28, 1903. Serial No. 159.209. (No model.)

ful Improvement in Metallic Ties, of which the following is a specification.

My invention relates to an improvement in metallic ties for street, interurban, and steam proper gage,

railways, the object being to provide means for rigidly securing the rails in position at the whereby spreading is absolutely prevented; and it consists in a tie composed of metal and adapted to be anchored in the road-bed, its construction being such as to insure its retention in place against movement, displacement, or objectionable vibration, in combination with chairs or frogs fitted to the base of the rails and cast in asingle piece, so as to require placing them thereon endwise of the rail, said chairs or frogsfitted to and adapted to be secured in dovetailed recesses provided for them in the upper edges of the ties.

It further consists in certain novel features of construction and combinations of parts, which willbe hereinafter described,and pointed out in the claims.

In the accompanying drawings, Figure 1 is a plan view of section of track in position on my improved metallic tie. Fig. 2 is a transverse section through the same on line 2 2 of Fig. 1, and Fig. 3 is a cross-section through one of the ties and chairs.

A A represent the metallic ties. These are preferably rolled from suitable metal and sub stantially iu the form indicated in the drawingsthat is to say, with concaved sides and wide bases, whereby to afiord adequate hearing in the road-bed and at the same time facilitate their being tamped in place in the road-bed against movement or vibration or accidental displacement. On their upper edges dovetailed recesses l 1 are formed, and in these the chairs or frogs 2 2 are adapted to be seated. These undercut or dovetailed recesses may taper or not crosswise of the tie, accordinglyas preferred, and the chairs or frogs are adapted to fit and be driven snugly into them crosswise of the ties.

The chairs or frogs 2 2 are preferably cast of malleable iron and are provided with dovetailed recesses 3 3, adapted to receive the bases 4 i of the rails 5 5, these chairs being made in a single casting and adapted to be placed on the rails by sliding them on at the end of rail before placing the rails in such numbers as there are ties spanned by the rail, save at. the ends of the rails, when they happen to be upon a tie, when one chair does fortheabuttingendsof tworails. Thechairs may be held in place, should this be deemed necessary, .by set screws 6 6, turned or punched into place. Likewise should there be any space caused between achair and the edge of its recess, due to expansion and contraction of metal, wedges 7 7 are adapted to be driven into the space, so that perfect lightness is always secured.

. From the foregoing it will be seen that the main parts to wit,the tie and the two chairseach of which is made in a singlepiece, the set-screws and wedges being supplemental and probably not always necessary, although provided in case they should be required. My peculiar method of stringing the chairs, as it were, upon the rails and then forcing them into their provided recesses insures perfect rigidity, for the reason that these chairs are cast in a single piece and fitted securely to their recesses or, if not so fitted, made to lit by the aid of the wedges, which latter are calculated to fill any spaces intervening between the recesses and chairs. The road-bed thus equipped is solid and substantial, and any danger of spreading or creeping of rails is absolutely precluded. It is also worthy of note that the construction of such a road is comparatively inexpensive.

It is evident that slight changes might be resorted to in the form and arrangement of the several parts described without departing from the spirit and scope of my invention, and hence I do not wish to limit myself to the exact construction herein set forth; but,

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination with a tie made of metal and provided with dovetailed recesses in its upper edge, of chairs cast in a single piece to fit these recesses, and provided with dovetailed recesses whereby they are slid entire construction really consists of three Ice upon the rail to be held endwise, and thence forced into the recesses in the tie, from one end thereof.

2. The combination with metallic ties hav- 5 ing dovetailed recesses in their upper edges,

of chairs cast in a single piece adapted to fit these recesses, and provided with a recess to receive a rail, and means for holding the chairs in place in the recesses in the ties.

3. The combination with a tie having dovetailed recesses in the upper edge, of chairs adapted to be seated in said recesses, and wedges for filling any space between the chairs and ends of the recesses.

4. The combination with rails and metallic ties having dovetailed recesses formed transversely therein, of chairs adapted to fit the bases of the rails, and the recesses in the ties,
