RAIL-JOINT.

SPECIFICATION forming part of Letters Patent No. 464,702, dated December 8, 1891. Application filed March 17, 1891. Serial No. 385,344. (No model.)

haveinvented certain new and useful Im-f= provements in Rail-Joints, of which the following is a specification.

This invention relates to improvements in rail-joints, but is more particularly designed as an improvement upon the invention set forth in Letters Patent of the United States, No. 407,302, granted me July 1G, 1889, being in the nature of a reversal of the parts therein set forth.

The prime object of this invention is to effect the tightening of the parts of the joint upon the rails by a combined lever and wedging action, which serves to not only bind the joint firmly to the rail,-but operates to brace the rail against the lateral pressure from the wheel-flanges and also to equalize the distribution of the weight in such manner that the binding force of the joint will be increased while the weight of the passing train is upon the joint.

Another object is to have the tightening devices of such character that while the power for tightening the joint upon the rails is applied from one side only it is distributed to both sides of the rails, so as to prevent any lateral movement or spreading of the saine.

These objects are attained by the devices illustrated in the accompanying drawings, in which i Figure 1 represents a top plan view of a railjoint embodying my invention, showing the same in position upon the rails Fig. 2, a sectional elevation thereof, taken upon the line 2 2 of Fig. l Fig. 3, a transverse vertical section of the same on the line 3 3 of Fig. lglooking in the direction indicated by the arrows; and Fig. 4, a similar Vview showing the relative positions of the parts before the joint is tightened. .y

Similar letters of reference indicate the same parts in the several figures of the drawings.

Iteferring by letter to the accompanying drawings, A indicates the top, B the web, and C the Iianges, of the rails, of usual construction, which rest upon and are supported by a base-plate D, of slightly greater width than the rail -'flanges, vwhich plate is upturned along its side edges, so as to permit at one side of the rail an overhanging shoulder or hook E and at the opposite side an inclined shoulder F, standingy at an outward angle from the rail-flange. At the side next the inclined shoulder is the wedging-lever plate G, which fulcru ms upon the rail, and between the inner end of which and the under side of the rail-top extends and is confined, a brace-plate H, the lower edge of which seats in a suitable socket provided in the end of the lever-plate; or, ifrdesired, a hinged connection of suitable form may be provided between these plates. The outer edge of the lever-plate is inclined, as shown at I, corresponding with the incline of the shoulder F, so that when the said plate is swung upon its fulcrum it will operate asa wedge against the inclined shoulder. The wedge-plate is perforated at suitable intervals so as to permit the free passage of screwbolts J, which extend up through the b-ase plate D and are provided with nuts K, bearing upon the broad face of theleverplate between the fulcrum thereof and the beveled out-edge thereof, so that `when the nuts are screwed down on the bolts the lever-plate will be caused to swing upon its pivot, forcing the brace-plate up against the under side of the top of the rail and the beveled outer edge of the lever-plate against the inclined shoulder F of the base-plate, thereby producing a wedging action upon the latter for the purpose now to be described. The base-'plate D at the opposite side of the rail may, if desired, be simply upturned to form the overhanging or hook-like shoulder, (illustrated by dotted lines in Fig. 3,) directly engaging the railange, which construction, so far as the tightening operation is concerned, would subserve the intended purpose; but it is preferably formed in the shape illustrated bythe full lines in the drawings, terminating ashort distance above the top of the rail-flange, so that one end of a lever-plate L may be inserted thereunder, which plate is fulcrumed on the i'ail-iiange and has confined between its op posite end and the under side of the rail-top a second brace-plate M, corresponding with the brace-plate H on the opposite side of the rail. It will thus bev seen that when the parts are first put together they will occupy some IOO what the relative positions shown in Fig. 4, and the result of screwing down the tightenin g-bolts will be to cause aslight lateral movement oi' the base-plate simultaneously with a vertical movement of the brace-plates under the influence of the two lever-plates, the lateral movelnentbeing due to theimpinging of the beveled edge oi the lever-plate G against the inclined shoulder F on the base-plate, which produces a wedging action of the lever-plate as the latter is tightened down in position. This lateral movement will continue until the lever-plate L has moved a sufcient distance to force the brace-plate M up against the rail-top, after which the further tightening of the bolts will cause a slight lateral movement of the wedging lever-plate G simultaneously with its movement upon its fulcruin until the brace-plate Il binds with sufficient tightness against the rail-top, the

tightening of the joint being then equally distributed between t-he two sides of the rail. Obviously tremendous force can be exerted by a joint operated in this manner, limited only by the strength of the parts to withstand the pressure which may be applied, as there is practically no limit to such pressure. Substantially the same results would be accomplished with the lever-plateL dispensed with, as well as the brace-plate M, and by employing the shoulder (shown by dotted lines in Fig. 3) directly engaging the rail-flangenthatis, so far as the tightening of the joint upon the rails is concerned; but the use of these plates is preferred because of the more equal distribution of the power and of the equalized bracing afforded the top of the rail by the opposing brace-plate.

For preventing the loosening of the nuts of the tightening-bolts by the jarring of the train any form of nutloek may be employed; but l have shown in the drawings a form of nut-lock especially adapted for use in connection with this joint, consisting of the alignlar bent plates il, the center portion O of which is arched upwardly so as to cover the nut of the middle tightening-bolt and is perforated to permit the passage therethrough of said bolt, on the end of which is secured a nut-lock P for holding the plate in position. The ends Q of the lock-plate are upturned and bear against the sides of the nuts upon the end tightening-bolts, thus serving to securely lock all of the nuts of the tighteningbolts against turning.

This device is both si1nple,durable, and effectual, and while any other form of lock devices inay be employed in connection with my invention l desire to claim this peculiar form of lock device in combination with my railjoint because ot its especial adaptability to this form of joint.

Creeping of the joint upon the rails is prevented by having the tightening-bolts work in suitable notches R, i'ormed in the edges of the iail-Iiange, which notches, while being of sufficient dimensions to permit the necessary contraction and expansion, will at the same time prevent the creeping or moving of the joint on the rails beyond a desirable limit.

Having described my invention, what l claim, and desire to secure by Letters Patent, 1s-
