RAIL-JOINT.

To all whom it may concern:

Be it known that'- l, EDGAR M. SMITH, a citizen of the United btates residing at New York city, county of New York, State of New York, have invented a certain new and useful Improvement in hail -'Joints, and declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and usethe same, refer ence being had to the accompanying drawings, which form a part of this specification.

My invention relates in general to rail joints, and more particularly to a joint for connecting rails of ditl'erent heights in laying tracks it sometimes occurs that the adjoining rails are of different cross section and consequently it is impossible to use the ordinary joint plates. In such event it is desirable that joint plates should be employed which will securely unite and at. the same time so support the adjoining ends of the rails that their tread surfaces will ac eurately aline.

The primary object of my invention is to provide a rail joint for connecting the ends of rails of different heights which will support the bases of the rails at different levels so that the tread surfaces will he in the same horizontal plane, and which will also resist the downward strain at the joint incident to the passage of trains.

A further ol'i ject oi my invention is to provide a rail joint plate for uniting the ends of adjoining rails of ditl'erent heights, which will be simple in construction, inexpensive in. imumtacture, and will possess great structural strength.

The embodiment of my invention herein disclosed maybe generally described as consisting of a pair of joint. plates each plate con'iprising an upper chord or lish plate oi two di'tl'erent heights so as to lit snugly between the heads and bases of the united rails and eoi'iforming to the shape of the base flanges of the rails, a lower chord depending from the upper chord and extending below the bases of the rails, a flange underlying and supporting the base of the smaller rail, and a shoulder tor supporting the base of the larger rail at a lower level than the base of the smaller rail.

My invention will be more fully described hereinafter with reference to the accompanying drawing in which'the same is illus-' Specification of Letters Patent.

trated as embodied in a convenient and practical form, and in which,--

Figure l is a perspective view; Fig. 2 an t-levational view of the opposite side of the joint plate from that shown in Fig. 1; Fig. 3. a sectional view on line 3-3 Fig. 2; and Fig. la sectional view on line l-4f Fig. 2.

The same reference characters are used to designate the same parts in the several figures of the drawing.

Reference characters A and B indicate the upper chord or fish plate which is of two diti'erent-heights to fit. snugly between the heads and base flanges of adjoining rails of dilferent heights. The portion A extends slightly higher than the portion B as it engages the smaller raih the under surface of the head of which must be supported at a slightly higher level than the under surface of the head oi? the larger rail in order that the tread surfaces of the rails may aline. The portion A of the joint plate is provided with a base flange i) adapted to extend bcneath the base of the smaller rail and support the same at a higher level than the base oi the larger rail. At the inner end of the flange l) is formed a shoulder (Z upon which is adapted to rest the base of the larger rail such shoulder being in a lower plane than the flange D so that. the base of the larger rail will be supported such a dislance below the base of the smaller rail that the treads of the two rails will aline horizontally. j

in order that the downward strain to which the joint. plates are subjected may be resisted, a lower chord C is provided which depends below the base flange ot'ihe rails. The lower chord is strengthened by means of webs e e which extend downwardly in inclined directions from the feet a Z) of the joint. plate. The lower chord (l is further strengthened by the base flange l) of the portion A of the plate and serves to support the shoulder 11. The joint plate is made integrally so that the lower chord, base flange 1), and shoulder (1 serve to mutually reinforce each other. The two plates employed to 'lorm a joint; are the reverse in constrluction of each other in order that the portions of the plates adapted to support the lower rail may be opposite each other and the portions of the plates for engaging the large rail may also lie on the opposite sides of the end of such rail.

-tween the correpsonding portions A A of the join plates and that its base rests upon the base flanges l) l)-- of the respective plates. in Fig. l, l indicates the larger rail engaged by the corresponding portions ll B o' the joint plates. The base of the larger rail rests upon the corresponding shoulders (5 d? and is thereby supported at a lower level than the base 1/ ol the smaller rail from the foregoing description it will be observed taat l have invented an improved rail joint. tor securely uniting the ends of rails of ditl'erent heights and which also adapted to withstand the downward strain to which a rail joint is subjected Having now fully described my invention, what 1 claim as new and desire to secure by Letters Patent is:
