FASTENING AND SEATING 0F GUARD-RAILS, 810., FOR STREET-RAILWAYS.

SPECIFICATION forming part of Letters Patent No. 472,165, dated April 5, 1892.

Application filed July 15, 1891.

To all whom it may concern.-

Be it known that I, JOHNA.DUGGAN,a citizen of the United States, residing at Quincy, in the county of Norfolk and State of Massachusetts, have invented certain new and useful Improvements in Fastenings and Seatings of Guard-Rails and other Rails for Street-Railways; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in fastenings and seatings of guard-rails and other rails for street-railways; and the object of my improvement is a chair adapted to receive both the main and guard rail, with means for firmly securing .the rails thereto,- thus avoiding the necessity of using special rolled guard-rails and enabling builders of streetrailways to construct guard-rails by the use of the ordinary T or girder rails by bending said rails to the curves required and securing them in proper position by the said chair and fastenings.

In the accompanying drawingslhave shown in Figure 1 arailroad-track on acurve; in Fig. 2, a section through main and guard rail, showing the chair on which both are seated; in Fig. 3, a side View of the rails and chair; in Fig. 4, a plan view of the chair, the rails being removed; in Figs. 5 and 6, a detail of the clamp, and in Fig. 7 a section showing substantially the same chair and fastenings applied to a different shape of guard-rail.

A A A are the railroad-ties; B B, themain or running rails, and O the guard-rail placed as usual, being always higher than the running-rail, in order better to guide the flange of the wheel WV, as shown in Fig. 2.

D is the chair, made of cast-iron or other suitable material, spiked to ties in the customary manner. The top or seating surface of this chair is adapted to the different heights of the guard and running rail, as shown in Figs. 2 and 7.

The chair D is provided with ear-shaped clamps E E, fitting over the side pieces h h of the chair. Clamp E is an improvement on that described in the application for Letters Patent filed by me October 3,1890, Serial No.

Serial No. 399,620. (No model.)

367,124. This improvement consists in providing the clamp with a rib g, placed at the narrow end of the clamp. This rib serves the threefold purpose of making the clamp stronger, of covering a larger space on the lower flange of the rail, so that the same chair and clamps will work for rails of different Widths of flange, and of offering a larger projection beyond the side pieces 71 h to strike and hit with the hammer in driving the clamp to its proper position.

In thus constructing my clamps it becomes necessary to make a right-hand and a lefthand clamp for each chair, the flange being always at the narrow end of the clamp-that is, at that end to which the hammer is applied in driving the clamp onto the chair. The end opposite to the rib g is chamfered slightly on the inside, so that it may be placed readily in position without liability to catch or bind.

This construction is shown in Fig. 5. The inside lower line (shown as 1 2 in Figs. 5 and 6) is made tapering, so as to conform to the tapering line of the corresponding part of the side pieces h h on the chair D, as shown in Fig. 3. The filling-blocks b and bolts asecure the running-rail B and guard-rail C in their proper distance from each other and prevent spreading apart. As the tendency of the wheels of a moving car is to push the guard rail 0 toward the center of the track, I provide on my chair a brace f, which fits against the center web and up under the head of the rail. This brace'carries any lateral strain on the head of the rail directly to the base of the chair and relieves the clamp opposite to the brace from any undue strain, which in the event of a very high (or deep) rail and a very low chair would be severe.

What I claim, and desire to secure by Lettel-s Patent, is-

1. The combination of the main rail 13, the guard-rail 0, both seated on the chair D, and the clamps E, bearing upon the upper and outer surface of the rail-flange, substantially as and for the purpose above described.

2. The combination of the main rail 13, guardrail 0, filling-block b, rails 13 and 0 being seated on the chair D, and clamps E, bearing upon the upper surface of the rail-flanges, substantially as and for the purpose above described.
