STREET-RAILWAY CONSTRUCTION.

SPECIFICATION forming part of Letters Patent No. 375,854, dated January 3, 1888.

Application filed OctoLer 24, 189. Serial No. 253,162.

To all whom it may concern.-

Be it known that I, RnYNoLDs T. Wanna cltizen of the United Statesresiding at Boston, in the county of Suffolk and State of Massachusetls, have invented a new and useful Improvementin Street-Railway Construction, of which the following is a specification.

The object of my invention ist-o construct a substantial street-railway road-bed at a very low cost.

My invention consists in the peculiar construction of the chairs and key-bolts, whereby I am able to'secure a rail having a web and a bulb or fillet on its lower end into the chairs.

My invention further consists in the construction of a chair to hold the ends of two adjacent rails, as hereinafterdescribed, and particularly pointed out in the claims.

Referring to the drawings, Figure 1 represents a side view of a sleeper and a vertical cross-section of a rail and chair with the two sides of the chair clamped over the Web of the rail by a key-bolt passing through the chair underneath the rail. Fig. 2 is a side elevation of the same. Fig. 3 is a side elevation of two adjacent rails secured into one chair to form a connecting-joint.

A represents a rail of any desired form of tread, having a web,B, at or near its center on its under side, and having a bulb or fillet, O, on lower end.

D is a chair made in two parts suitably ribbed and of the form shown, so that the up per ends fit under rail A and the sides fit close to web B and bulb or fillet O. The chairs D are spread at their bottom transversely from the rails of sufficient width to insure stifl'ness to the track and prevent the rails A from rolling or moving when heavy teams are passing in or out or over the track. The chairs D are secured to a wooden sleeper, E, by lag-screws e,- and to further insure the bottom of chairs D from spreading at their bottom I drive into the sleeper, close to the ends of the chair, spikes or stubs f. The sides of chairs D are secured together over web B and bulb or fillet O of rails A by key-bolt F, passing through under bulb or fillet O, and a key, G, driven in tight, as shown, thus making a very substan- (No model.)

tial fastening and without any holes in the rails.

In Fig. 3 I show two adjacent rails, A A, secured at their ends in one chair, the chair being made of suitable width and having two key-bolts, F F, passing through the chairs under the rails A A, and a similar key-bolt, H, passing through the chair at or about the center of the web of the rail and keyed, as shown.

The ends of the two adjacent rails where key H passes through are provided with slots or half-round recesses, sufiicient space being left between joints of rails for expansion and contraction.

The chairs D may be secured to an iron sleeper,and may be made to fit the web on un der side of any rail, and any required number of single chairs may be put between the joint chairs to insure a solid road-bed, and all secured to a sleeper. Having thus described my invention, what I claim is.

1. A metal chair made in two halves, each half being spread at its bottom, as shown, and having suitable vertical ribs, which form at their upper ends a broad bearing-surface for the rail to rest upon, in combination with a girder-rail having a web at or near its center on its under side and provided with a bulb or fillet on its lower edge, the two halves of said chair being secured together over web and bulb or fillet of the rail by a bolt passing through the chair under but close to said bulb or fillet of rail and secured to a sleeper, substantially as shown and described. I

2. The combination of a metallic chair and two adjacent rails, the rails being held at their ends in said chair by key-bolts passing under and between the ends of the rails, substantially as and for the purposes set forth.

3. In street-railway construction, a metal chair made in two halves, each half being formed at its upper end to fit the lower parts of a rail provided with a Web and bulb or fillet, each half of the chair being spread atits lower ends and secured to a sleeper, the two halves being also secured together over web of rail by a bolt under the bulb or fillet, thereby dispensing with holes in the rails, and having strengthening-ribs which form at their tops a broad bearing-surface for the under side of the head of the rail, substantially as shown and described.

4. In the within-described system of constructing street-railways, the combination of a girder-rail without bolt-holes, with a metal chair made in two halves, each half provided with strengthening-ribs, the upper ends of which form a broad bearing-surface for the under side of the head of the rail, and the lower ends being spread and secured to a tie or sleeper, and the two halves being secured together by a bolt passing close under the web of the rail, substantially as shown and dem scribed.

Intestimony whereof Ihave signed my name to this specification in the presence of two subscribing witnesses.
