This invention relates to track-fastenings for railroads; and it consists in the novel constructibn and combination of the parts hereinafter fully described and claimed.

In the drawings, Figure 1 is an end View of the track-fastening, partly in section. Fig. 2 is a plan view of the same." Fig. 3 is an end view showing a modification of the trackfastening.

A is a railroad-rail of any approved construction or cross-section.

B represents the joint-plates of the rail, which also may be of any approved construction, but which are preferably angle-shaped in cross-section.

C is a tie, which extends crosswise under the rails.

D represents chair-plates provided with longitudinal ribs ol on their upper sides and bosses d', having holes e.

E represents screws having projections f on one side of their upper end portions and square portions f at each end for engaging with a Wrench. The chair plates are arranged under the rail with the ribs d against the edges of the joint-plates, and the screws are screwed into the tie until the projections Serial No. 168.434. (No model.)

means for removing the lower part of the screw by means of a wrench should it become broken od below the projection.

In the,I modification shown in Fig. 3 the joint-plates are dispensed with and a single chair-plate is used. This chair-plate D' cxtends under the rail, so that two screws are passed through holes in it. In the form ot the device shown in Figs. l and 2 two chairplates are used, and each chair-plate projects part way under the rail.

l. In a track-fastening, the combination, with a chair-plate, and a tie; of a screw which engages with the said tie and which has a projecting lower end which engages with the ground below the tie, and a projection on the upper part of the said screw for holding the rail in position.

2. In a track-fastening, the combination, with a tie, and a chair-plate provided with a longitudinal rib, a boss and a hole through the boss; of a screw which engages with the said tie and which has a projecting lower end which-en gages with the ground below the tie, said screw being passed thro ugh the said hole in the chair-plate and providedwith a projection on its upper part for holding the rail in place. l

3. In a track-fastening, the combination, with a tie, a rail, and two angle-shaped jointplates; of two chair-plates each extending part way under the rail and provided with ribs which bear against the joint-plates, and screws which pass through holes in the said chair-plates and engage with the said tie, said vscrews being provided with projections which engage with the said joint-plates.
