RAIL-JOINT.

SPECIFICATION forming part of Iietters Patent No. 622,033, dated March 28, 1899.

Application Sled December 24, 1898. Serial No. 700,229. (No model.)

T0 (all 11171/0771/ t muy concern:

Be it known that I, JOI-IN BAKER, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Rail-Joints, of which the following is a specification.

My invention pertains to rail-joints; and its object is to provide a novel and efficient joint in order to overcome the objections to the ordinary joint, in which the car-wl1eels bear upon and are carried by the rails at the joint proper at the meeting ends of the rails, which joint receives the entire pressure or weight.

My object is to produce a joint device in which the car-wheels are designed to bear upon a block or connecting-piece at the ends of the rails, so that a smooth and continuous surface is always provided for the Wheels, as if the track were made of one continuous rail.

The novelty and advantage of my const-ruction of joint will be understood from the description hereinafter given. l

In the drawings, Figure l is a plan of my joint; Fig. 2, a side elevation of the inner face of the joint; Fig. 3, a side elevation of the outer face of the joint; and Figs. 4 and 5, sections taken on the lines 4 and 5, respectively, of Figs. 1 and 2, respectively.

Instead of the usual straight-ended rails I employ rails l and 2, which have been preliminarily curved outwardly Vor offset, as shown clearly in Fig. 1. Upon the outer face of the railsis arranged an angle-bar 3, corresponding in shape to the curvature of the rails at their meeting ends and having tapered ends to accommodate the wheels in case they are double-anged. This bar may be provided with a base portion orA plate 4 to rest upon the ties 5, as seen in Figs. 4 and 5, and to forni a seat or chair for the rails. It is obvious, however, that such base portion may be omitted and the rails allowed to rest directly upon the ties.

The outward curvature of the rails, as described, forms a spaceor concavity which is lled by an inner or second angle bar or block 6, which tapers in thickness from the center to the ends and whose edge '7 forms a continuation of the straight or main portion of the rails on the inner or wheel-nan ge side thereof.

As seen in Fig. 4, the bar or block G is provided with a lower angular portion S, which may rest'at its lower end upon the base-plate 4, if such a plate is used.- This block also rests along its entire length upon the base of the rails, so that the block will not only carry the Wheels, but will prevent the dropping of the joint, so that a wide-tread wheel will run smoothly over the block and also the joint. In order to secure the parts together, I employ any suitable number of bolts 9, passing transversely through the rails and the anglebars.

The ends of the rails lie inthe same plane or line and may therefore be considered as meeting or abutting each other, although, of course, the usual space may be left between such ends. The term meet is therefore used in the claims with such understanding.

As is shown in Figs. 2, 4, and 5, the bar G is inclined gently from its center toward the ends l0, which are slightly below the top plane or tread-face of the rail, the central portion being slightly thereabove, as seen in Fig. 5. The obj ect of this construction is to avoid any joint between the rail and inner bar andA allow the wheels to take the bar easily when they run from the rail proper upon the bar.

Immediately beyond thepoint ot' the first curvature of the rail the wheels will bear upon the block 6 and will be carried by such block to the next rail. My device thus forms practically a continuous rail, and there is not the usual joint on which the wheels bear, inasmuch as the wheels are carried by the block at the meeting ends of the rails. These rails may be curved or oifset to any extent and the block may be proportioned accordingly, so as to form a continuous lineal edge with the main parts of 'the rails. It is obvious that my joint may be used on a curve as well as upon a straight track, and in both instances the general construction and principle will be the same. In both instances the bar or block 6 will form a continuation of the main portions of the rails whether the same are curved or straight; but in the former instance it is obvious that it will be necessary to slightly curve the wheel-flange side 7 of the block 6, so as to complete the curvature of the track.

It will be understood that when the base- IOO plate 4 is used the entire joint may be spiked to the ties by means of the ordinary spikes 11, whose heads are driven against the bar 3, and that when such plate is not used the heads of the spikes will be driven against the base of the rails in the usual and well-known manner. My joint has a considerable extent of bearing upon the ties or support, which is a construction of advantage to prevent spreading or displacelnent, either on a straight or curved track, caused by the pressure of the wheel-flange on the rail.

Although I have described more or less precise forms and details of construction, I do not intend to be understood as limiting myself thereto, as I contemplate changes in form, the proportion of parts, and the substitution of equivalents as circumstances may suggest or render expedient and without depart-ing from the spirit of my invention.

I claiml. A rail-joint comprising two rails whose ends meet and are outwardly curved and a bar or block filling the recess or eoneavity formed by said curvature.

2. A rail-joint comprising two rails whose ends meet and are similarly outwardly curved and a bar or blocl; filling the recess or concavity formed by said curvature and having its face on the inner side of the track corresponding in direction with the portions of the rails beyond their outward curvature to form a continuous rail and having its other side corresponding to the curvature of the two rails and means for securing said block in place.

3. A rail-joint comprising two rails whose meeting ends are outwardly curved, a har or block filling the recess or concavity formed by said curvature, and a second bar arranged upon the outside of the meeting ends of said rails and curved t-o correspond with said eurvature of the rails and means f'or holdin g said parts together.

4. A rail-joint comprising two rails whose meeting ends are outwardly curved and a bar or block filling the recess or eoneavity formed by said curvature, said block being at its eenter slightly above the top plane of the rails and inclining gently toward each end which is slightly below said plane.

5. The combination of two rails having meeting or abutting ends similarly curved and a baror block arranged adjacent to said meeting ends and forming a continuation of the main part of the rails on the wheel-flange side thereof.

6. A rail-joint comprising two rails whose ends meet and are outwardly curved, a bar or block filling the coneavity formed by said eu rvature and forming a continuous rail in connection with the portions of said rails beyond their said ends, and a second bar or'bloek arranged on the outside of the said curved ends of the rails and having a hase-plate on which said rails rest.

7. Arail-joint comprising two rails l and 2 whose meeting ends are outwardly curved, a block G filling the concavity formed by said curvature and having its central portion slightly above the top plane of the rails and sloping gently to the ends 10 which are slightly below said plane and a bar 3 arranged outside said curved ends.
