RAIL-JOINT SUPPORT.

Specification of Letters Patent.

Patented se eso, 1913.

Application filecl August 31, 1912. Serial No. 218,141.

'wan and Dominion of Cztnadzuhave invented new' and useful Improvements in Rail- Joint Supports, of which the following is a specification. I The invention relates to a support for railway rails and more'particularly to the class of rail joint supports.

The primary object of the invention is the provision of a support in which the meeting ends of rails may be prevented from sagging one with respect to the other and which will materially reinforce said joint so as to strengthen the rails.

Another object of the invention is the provision of a rail joint support or bottom splice bar which is simple in construction, strong, durable, thoroughly reliable and efficient in its purpose and inexpensive in manufacture. r

\Vith these and other objects in view the invention'consists in the construction, combination and arrangement of parts as will be hereinafter more fully described, illustrated in the accompanying drawing, and

-. pointed out in the claim hereunto appended.

In the drawing: Figure 1 is' a side elevation of a railjoint showing thedevice constructed in accordance with the invention applied. Fig. 2 is a perspective View of the support removed. Fig. 3 is a vertical transverse sectional view on the line 33 of Fig. 1. Fig. 4 is a fragmentary perspective view of one ra'l end. Fig. 5 is a fragmentary side elem ion of a slight modification of the angle bars or plates used with the sup port. F in. 6 is a sectional view on the line 6-6 of Fig. 5.

Similar reference characters indicate corresponding parts throughout the several views in the drawing.

Referring to the. drawings by numerals, 5 and 6 designate complementary meeting ends respectively of railway rails which are of the ordinary well-known construction,

and. are connected together by means of angle bars 7 disposed at opposite sides there of against the webs of the same, so that said bars will rest upon the base flanges of the rails in the ordinary well-known manner, Each rail end is provided with

elongated slots

8 and 9 in the web and base flanges respectively thereof to receive independent series of bolt members 10 and 11 which pass flanges of the rail .endsfor connecting the same. The

elongated slots

8 and 9 will permit the usual expansion and contraction of the. rails at the joint.

The rail joint support comprises a plate 12 formed with reversely beveled upper surfaces 13 provided with bolt receiving openings or holes 14 for receiving the series of bolt members 11 which carry the usual nuts 15 for the tightening of the bolt members, the plate 12 being disposed at the bottom or base flanges of the rails so as to bridge the joint and thereby prevent the possibility of the sagging of one rail end with respect to the other. The flat portion 16 between the rcversely beveled surfaces 13 of the plate 12 will sustain the tread portions of the rails flush so as to permit the rail ends to evenly wear at the'joint and to avoid pounding of the car wheels when passing thereoven' In Figs. 5 and 6 there is shown a slight modification of the invent on wherein the fish plates 17 have formed on their angular portions 18 laterally extending flanges at right angles to the webs of the rails and projected beyond the base flanges thereof, the said flanges 19 being provided with suitable bolt receiving openings 20 for receiving bolt members 21 which do not pass through the base flanges but are engaged with the supporting plate 22 on which are "through the angle bars 7, the webs and base superimposed the rail ends. Thus, in this manner the latter are possessed of maximum strength by reason of the fact that the base flanges are devoid of perforations or holes therein.

From the foregoing description, taken in connection with the accompanying drawing, it is thought that the construction and operation of the invention will be clearly understood, and therefore a more extended explanation has been omitted.

What is claimed is:

The combination with the meeting ends of railway rails and angle plates connecting the same, the said rail ends bemg formed with longitudinally directed elongated openings in their webs and bases, of a rail joint support comprising a plate underlyin the joint between the rail ends and having a thickened medial portion, and a,- plurality of bolt members passed through the slots in the rail ends and engaged in the angle and joint supporting plates, the said bolt members being located at opposite sides of the abutting ends of the rails.
