ROY 1. ETCHISON, OF SWISSVALE, PENNSYLVANIA RAIL-JOINT.

To all whom it may concern:

Be it known that I, ROY P. ETOHISON, of Swissvale, Allegheny county, Pennsylvania, have invented a new and useful Improvement in Rail-Joints, of which the following is a full, clear, and exact description,'reference being had to the accompanying drawings, formingpart of this specification, in which-- Figure 1 is a transverse vertical section taken through a rail joint embodying my invention; Fig. 2 is a side elevation of the same; and Fig. 3 is a sectional perspective view.

My invention has relation to rail joints, and is designed to provide a secure and efficient joint which can be readily manufactured and assembled, and in which the use of the usual joint boltsis obviated.

In the accompanying drawings, in which I have shown the preferred embodiment of my invention, and which will now be described, the numeral 2 designates the end portions of two track rails which are united by my improved joint.' In accordancewith my invention I securely rivet to each side of the joint-forming end of .each of the rails 2 a bar 3 having the inwardly beveled edges 4.

5 designate the splice bars, which may in general be of any suitable form, but each of tion.

which is provided on its inner face with a dovetailed groove 6 adapted to make a close driving fit with the inwardly beveled edges of the bars 3. The bars 3 are preferably secured to the rail ends by means of; the rivets 7 before the latter. areplaced in posi- The rails are then properly placed, and the splice bars are applied and driven endwise over the bars 3, thus making a secure and efficient joint. In order to prevent any creeping movement of the rails relatively to the splice bars, the latter, together with the base flanges of the rails, are preferably provided with registering openings or slots 8 through which spikes may be driven into the ties. In the drawings, 1 have shown the holes in the rail webs somewhat larger than the rivets, but this clear- Specification of Letters Patent.

from the provision of a simple and eificient joint, without the use of bolts and nuts, and free from parts which can work loose in service. I 7

It will beobvious that my invention is susceptible of various modifications in detail without departing from the spirit and scope thereof as defined in the appended claims. Thus, it is obvious that the form of the retaining bars may be changed, and that said bars instead of being riveted to the rail ends may be secured thereto in any other suitable manner as by welding.

What I claim is 1. In a boltless rail joint, a T-rail having an ordinary plain-faced Web, separately formed retaining bars secured to opposite sides of the web, and splice bars having grooved inner faces arranged to be driven over the retaining bars, substantially as de- Patented Apr. 9, 1912.

an ordinary plain-faced web, and separately formed retaining bars secured to opposite sides thereof by connections extending through the rail web, said bars being arranged to be engaged by internally grooved splice bars, substantially as described.

3. In a boltless rail joint, a rail having separately formed retaining barssecured to opposite sides of its web by rivets extending through holes in the web, the heads of said rivets being substantially flush with the retaining bars and the bars being arranged to be engaged by internally grooved splice bars, substantially as described.

4:. In a boltless rail joint, a T-head rail having separately formed bars secured to opposite sides of its web by through connections, and splice bars with inner grooves engaging the retaining bars, the splice bars and rail having open-ended slots to receive means for preventing relative creeping, substantially as described.

In testimony whereof, I have hereunto set my hand.
