NATHANIEL M. CORNELL, OF ROYALTON, MINNESOTA.

RAILROAD-RAIL JOINT.

SPECIFICATION forming part of Letters Fatent No. 635,918, dated October 31, 1899.

Application filed July 22,1899- Seria1N0.'724,804. (No model.)

To all whom it may concern.-

Be it known that LNATHANI L M. CORNELL, a citizen of the United States, residing at Royalton, in the county of Morrison and State of Minnesota, have invented certain new and useful Improvements in Railroad-Rail Joints; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. The invention relates to railroad-rail joints and the object of the invention is to provide a simple, durable, and inexpensive joint which will reduce to a minimum all liability of the rails becoming separated and which will form practically a continuous track, thereby permitting of faster running of the trains without increasedfianger of accident.

To this end the invention consists in certain features of construction and combination of parts, which will be hereinafter fully described, and particularly pointed out in the appended claim.

In the accompanying drawings, Figure 1 is a side elevation of my improved rail-joint. Fig. 2 is a top plan view. Fig. 3 is a crosssectional view on the line X X of Fig. 2. Fig.

' 4 is a similar view on the line Y Y of Fig. 2.

Fig. 5 is a top plan view of one of the splicebars removed.

In the accompanying drawings the same reference characters indicate the same parts of the invention.

1 denotes the adjacent ends of two railroad-rails.

2 denotes the splice-bars, the upper surfaces 3 of which form a continuation of the tread of the track and have their inner faces cut away, so as to form a lap-joint and stopshoulders 5. The outer ends of these bars are formed with longitudinally projecting arms 6, the sides of which are shaped to conform to the web of the rail and the edges of which fit snugly against the base and the under side of the tread of the rail. At the rear of the arms are stop-shoulders 7 and 8, against which the end of the rail abuts. The arms and the end of the rail are formed with through-apertures 9, through which pass bolts 10, provided with the usual nuts 11.

12 denotes the fish-plates, which are provided with a base 13. Bolts 14 pass through apertures 15in the fish-plates and elongated apertures 16 in the meeting ends of the splicebars and are provided with nuts 17.

By referring to Figs. 1 and 2 it will be noted that the adjacent ends of the bases of the rails abut against the shoulders 7- and 8 of the splice-bars, so as to take all unnecessarystrain ofi the bolts 10, and it will further be noticed by referring to Figs. 1 and 2 that there are slight spaces between the ends of the base of the rail and the ends of the fishplates to permit of the movement of the rail when affected by expansion or contraction or when the joint is subjected to undue jar, thus relieving the bolts 14 of unnecessary strain.

Having thus described the invention, what is claimed, and desired to be secured by Letters Patent, is

The combination with the adjacent'ends of two railroad-rails, of splice-bars lapped together and located between said rails and forminga continuation of the same, said bars being provided with longitudinally-extending arms to engage the webs of said rails, and with shoulders 7 and 8 against which the ends of said rails abut, fish-plates embracing the lapped portions of said splice-bars and provided with a base upon which the splice-bars and ends of the rails seat, the length of the fish-plates being less than the distance between the ends of the rails, bolts extending through apertures in the fish-plates and elongated apertures in the lapped portions of the splice-bars, and bolts extending through the ends of the rails and the longitudinal arms of the splice-bars, substantially as and for the purpose set forth.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

NATHANIEL M. CORNELL.
