T0 025 20 7mm it may concern Be it known that I, JAMEs Been, a citizen of the Dominion of Canada, of the city of Peterborough, in the county of Peterborough, in the Province of Ontario, Canada, have invented certain new and useful Improvements in Railway-Chairs, of which the following is the specification.

My invention relates to improvements in railway chairs and the object of the inven-- tion is to provide means for holding the rail ends together so as to retain them in absolute alinement one with the other allow of a free limited longitudinal movement and in which there will be no danger of the rail becoming loose by vibration due to passing trains and it consists essentially of a chair body provided with a central longitudinal groove into which the base flanges of the rail ends fit and inwardly presented side grooves located at each side of the central groove of the chair body, the base of such grooves being parallel with the rail ends and the side wall edge of such grooves converging inwardly from each end of the chair body toward the center of the body opposite the rail joint and wedge pieces fitting between the web of the rail andthe inwardly converging edge portion of the side groove wall of the chair body, and a flange like extension extending laterally outwardly from each wedge piece into the inwardly presented side grooves of the chair body, notches formed in the outer edge of each flange like extension, orifices formed in the chair body above and below such notches through which notches suitable spikes are designed to extend and projections extending upwardly from the base of the central groove of the chair body into slotted recesses formed in the bottom face of the base flange of the rail as hereinafter more particularly explained by the following specification.

Figure 1, represents a perspective view of my rail chair supported upon a suitable sleeper and in which the rail ends are shown secured in position. Fig. 2, is a sectional plan taken through the rail immediately above the chair. Fig. 3, is a similar view to Fig. 2 showing the upper wall of the inwardly presented side grooves of the chair body removed, the portion forming the base of the groove being in section. Fig. 41, is a longitudinal sectional view. taken through the center of the rail ends. Fig. 5, is a cross and yet section on line 00-y Fig. 4:- Fig. 6, is a cross section online w Fig. 2.

. In the drawings like letters of reference indicate corresponding parts in each figure.

1 and 2 indicate the rail ends.

3 indicates in Fig. 1 a portion of a sleeper.

4- indicates the chair body resting upon the sleeper.

5 indicates a longitudinal groove formed in the upper face of the chair body and into which the base flanges P of the rail fit.

6 and 7 indicate side ribs formed on each side of the upper face of the chair body. 6 and 7 indicate inwardly presented grooves formed in the side ribs 6 and 7 The bases of the grooves'6 and 7 extend parallel with the side of the chair body and the side faces of the rail ends 1 and 2. The inwardly presented edges formed by the portion 8 forming the upper side walls of the grooves 6* and 7 incline inward toward the rail from both ends of the chair body to the center of the chair body opposite the joint between the rail ends 1 and 2.

9, 9 indicate wedge pieces having comparatively broad outer ends and narrow inner ends. The wedge pieces are driven into place between the vertical web of the rail ends 1 and 2 and the inwardly converging edges of the wall portion 8. Each of the wedge pieces 9 is provided with a lateral outwardly extending flange portion 9 which fits into the grooves 6 10, 10 indicate notches formed in the edges of the flange like extensions 9*. The notche 10, when the wedge pieces are driven into position, are in vertical alinement with orifices 11 and 12 formed in the upper and lower walls of the groove 6 (see Fig. 6).

13, 13 indicate projections extending upwardly from the chair body into recesses 13 formed in the bottom face of each of the rail ends. The recesses 155* permit of a limited longitudinal movement of the rail when the rail expands or contracts due to a climatic change.

From this description it will be seen that all that it is necessary to do when securing a rail is to place the chair upon the sleeper, place the rail ends in the longitudinal groove 5 and then drive the wedge pieces 9 between the vertical webs of the rail and the inwardly extending edges of the grooves 6*. When the wedge pieces 9 are driven home the chair may be spiked down by driving the spikes through the orifices 11 and 12 and longitudinal movement of the rail when sub-v notches 10 into the sleeper. By such con struction the rail ends are absolutely held in a rigid position and cannot work loose, as is often the case when connected together by fish plates now commonly in use, and in which there is no danger ofi the rail ends becoming loose due to the gradual loosening of the spikes holding the rail by the continual vibration of passing trains and at the same timeI have provided such a means, which although holding the rail securely in absolutealinement, will allow of the free ject to climatic changes.

What I claim as my invention is. V 1. A rail chair comprising a chair body provided with a longitudinal groove into which the base, flanges of the rail ends are designed to fit, upward extensions extending along each edge of the chair body and provided with inwardly presented grooves, the upper Wall of which is inclined from I 7 each end ofthe chair body toward the center'of the chair body, wedge pieces provided with lateral flanges designed to fit into the aforesaid grooves and notches through which designed to extend.

' 2. A rail chair comprising provided with a central longitudinal groove into which the base fianges'of the rail ends are designed to fit, upward extensions eX- tending along each side of the chair body,

the upper portions of the inwardly present- 35 the chair to the center and ed faces of which are inclined; inwardly from each end of the lower portions of to the rail, and wedge chair body from each end and having portions bearing'against the inwardly'inclined portions and portions bearing against the parallel portions of the chair body.
