RAILWAY-RAIL JOINT AND CHAIR.

SPECIFICATION forming part of Letters Patent No. 792,633, dated June 20, 1905.

Application filed January 23,1905- Serial No. 242,390.

Railway-Rail Joint and Chair, of Which the following is a specification.

This invention relates to combined railway joints and chairs, and has for its object to improve the construction and increase the strength and efficiency of devices of this character.

\Vith these and other objects in view, which will appear as the nature of the invention is better understood, the same consists in certain novel features of construction, as hereinafter fully described and claimed.

In the accompanying drawings, forming a part of this specification, and in which corresponding parts are denoted by like designating characters, is illustrated the preferred form of embodiment of the invention capable of carrying the same into practical operation, it being understood that the invention is not necessarily limited thereto, as various changes in the shape, proportions, and general assemblage of the parts may be resorted to without departing from the principle of the invention or sacrificing any of its advantages.

In the drawings thus employed, Figure 1 is a side elevation of one of the improved joints and chairs viewed from between the rails, and Fig. 2 is a similar view from the outside. Fig. 3 is a transverse section, enlarged, on the line 3 3 of Fig. 1. i is a transverse section, enlarged, on the line t 4 of Fig. 1.

The improved device comprises a base-plate 10, extending beneath the abutting ends of the rails 11 12 and preferably extending over three of the transverse ties 13, with the adjacent ends of the rails above the central tie. The plates 10 are each formed at one side with a clamp portion 14:, conforming to the upper surface of one side of the tie-flange and one face of the web and forming a clamp- A clamp-bar 16 embraces the vertical webs of the rails at the side opposite from the plate portion 14, and the'plate and bar are secured in position by transverse clamp bolts 17, spaced apart at suitable intervals, the bolts having heads 18 and nuts 19 in square or any other than circular form. TWO locking-plates 21 22 are disposed upon the plate portion 1a and bar 16 and provided with apertures 23 24 to receive the heads 18 on one side and nuts 19 on the other side, all the apertures except one in each plate being elongated. longitudinall y to provide means for expansion and contraction under changes of temperature, the excepted apertures being circular to receive a longer clamp-bolt 25, with its head 26 and nut 27 hearing, respectively, against the plate portion 22 and the clamp-plate 21. A springkey 29 is preferably inserted through a suitable aperture in the threaded end of the bolt 25 outside the nut 27 to form alock to the nut and effectually prevents any danger of the accidental displacement of the binding nut. By this simple means the bolt-heads and nuts will be locked from backward rotation, and there will therefore be no danger of the loosen ing of the nuts under the severe jars and concussions to which they will be subjected by the passing trains, while at the same time the expansion and contraction incident to devices of this character is provided for by the elongated form of the bolt-apertures.

The plate 10 is provided at suitable intervals with spike-receiving apertures, and these apertures are located through the bearing-rib 15, with the inner Wall of the apertures in vertical alinement with the inner face of the rib, so that when the spikes (indicated at 20) are driven into the tie 13 through the aperture the stocks of the spikes will bear against the adjacent edges of the tie-flanges of the rails and their lateral heads will bear over the tie-flanges. The heads of the spikes will thus bear downwardly upon the tie-flanges, While at the same time the bearing-ribs 15 will effectually prevent anylateral movement of the rail. The necks of the spikes are thus protected from shearing action by the relatively sharp edges of the tie-flanges, and the
