JOHN ELLMORE, OF ALTOONA, PENNSYLVANIA.

RAIL-JOINT.

SPECIFICATION forming part of Letters Patent No. 772,650, dated October 18, 1904.

Application fi led June 18, 1904,

T at whom it may concern:

Be it known that I, J OHN ELLMORE, a citizen of the United States, residing at Altoona, in the county of Blair and State of Pennsylvania, have invented a new and useful Improvement in Rail-Joints, of which the following is a specification.

This invention relates generally to railjoints, although the principle of the invention is applicable to joints for all kinds of channel beams or girders.

The object of the invention is to provide an exceedingly simple and durable joint by means of which the meeting ends of railroadrails or channel-beams can be securely interlocked and all bolting or riveting entirely avoided.

Another object of the invention is to provide a joint which shall be of such construction that it will be able to withstand vertical strain as well as lateral or horizontal strain, and a still further object is to provide a joint which will completely avoid the use of splicebars or fish-plates, a single binding-plate being employed to prevent longitudinal movements of the rails or beams.

With these various .objects in view the invention consists in the novel features of construction and arrangement hereinafter fully described, and pointed out in the claims.

In the drawings forming a part of this specification, Figure 1 is a perspective view showing the practical application of my invention to the meeting ends of two railroad-rails. Fig. 2 is a detail perspective view showing the end of one rail. Fig. 3 is a similar view showing the opposing end of the other rail. Fig. 4 is a detail perspective View of the same end taken from the opposite side, a portion of the head of the railbeing broken away to disclose the recess in said head. Fig. 5 is a detail perspective view of the angled tie-plate. Fig. 6 is a sectional elevation taken on the line 6 6 of Fig. 7. Fig. 7 is a horizontal sectional View taken on the line 7 7 of Fig. 6. Fig. 8 is a top plan view of the ends of the rail disconnected, and Fig. 9 is a transverse section on the line 9 9 of Fig. 7.

Referring to the drawings, A indicates the end of one rail, and B the opposing end of offset or shoulder A.

the railare substantially the same as heads and bases now'in common use. The web A however, is formed with an oblique offset portion A" at a point where the head of the rail terminates, as most clearly shown in Figs.

2 and 8, the remaining portion A of the rail being parallel to the main body of the web,

but to one side thereof, owing to the oblique The portion A of the web also extends beyond the end of the base, as most clearly shown at A", and at its lower end is cutaway, as shown at A The base is recessed, as'shown at A, between the 0&- set 'A- and the end of the base, and the head of the rail is provided with a recess A in the lower face of the same adjacent the offset.

A bolt-opening A is produced in the base adjacent the end of the same. The-rail B has the tread B, base B and web B said web having an oblique offset or shoulder B, and projecting beyond the end of the head is the portion B which is parallel with the main portion of the web, but is arranged at one side on account of the oblique offset or shoulder. The base B of the rail B stops short of the end of the rail a distance which the base A of the rail A extends beyond the end of the tread A, and the extended portion B of the web B is out out, as at B, at its lower corner. The base 13 is also slotted at the end adjacent the web, as shown at B and in the lower face of the head of the rail is a recess B, said recess being upon the same side of the web as the slot B and directly over the same.

Rails or channel-beams having their ends constructed as herein shown and described can bequickly and easily interlocked, and when so locked they will be held firmly against vertical and lateral movement. In connecting the ends the portion A will fit into the recess B, and the cut-away end A will enter the slot B and the lower edge of the portion B will engage the recess or opening A, and the projection B will enter the recess A The oblique ofiset portions A and B contact with each. other, as most clearly shown in Fig. 7, and the ends of the treads and the ends of the bases are brought IOO firmly into contact with each other, and in order to hold said parts against longitudinal movement I employ an angled tie-plate C, having elongated openings 0 in the base thereof, through which the fastening-bolts are adapted to pass, said bolts passing, respectively, through the openings A and B, produced in the bases A and B respectively.

'Having thus fully described my invention, What 1 claim as new, and desire tosecure by Letters Patent, is-

1. The combination with the rails or beams having offset Web portions, said offset portions extending beyond both tread and base of the rails, the base of one rail extending beyond the tread of said rail, the tread of the other rail extending beyond its base, the tread of each rail having a recess in its lower side, the end of each projecting web portion being adapted to enter the recess of the opposing rail.

2. The combination with the rails or beams each having an oifset web portion projecting beyond the tread of the rail, the base of one rail projecting beyond the tread of said rail and the base of the other rail stopping short of the end of the tread, each projecting web portion being cut away at its lower end, each rail-tread having a recess in its lower side and the projecting portion of the base having a recess adapted to receive the projection carried by the opposing. Web portion.

3. The combination with the meeting ends of the rails or beams, one of said rails having its base projecting beyond the tread and the other rail having its tread portion projecting beyond the base, the tread portion of each rail having arecess in the under side thereof, the web of each rail projecting beyond the tread and base and having its outer end oilset, the extreme end of each projecting web portion being cut away at the end adjacent its lower edge, and the projecting base having a recess adjacent its end adapted to receive the projecting web portion.

4. The combination with the rails each having an ofl set web portion projecting beyond both tread and base of the rails, of the angular binder-plate adapted to be secured to the ends of the opposing bases, the base of one rail projecting beyond the tread of said rail and the tread of the opposing rail projecting beyond its base, each projecting web portion being adapted to engage the recessed portion produced in the lower sides of the heads of the rails.

5. A rail having its base projectingbeyond the tread and the web projectingbeyond both the tread and base, that portion of the web projecting beyond the tread being oflset and cut away at its lower end, the base having a recess produced therein adjacent its ends, and the tread of the rail having a recess in the under side thereof.
