To @ZZ whore@ t may concern:

Be it known that I, I-IosEA ALLEN, a citi- Zen of the United States, residing at OilCity, county oi' Venango, and State of Pennsylvania, have invented certain new and useful Improvements in Rail-Joints and I do hereby declare that the following is a full, clear,

and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form part of this specification.

This invention relates to rail-joints.

My rail-joint, as is the case with those of 4 the ordinary character, involves one or more fish-platesy and bolts carrying nuts, the bolts, as usual, passing through registering perforations in the rails and fish-plates.

It is one of the primary objects of my present invention to hold these bolts against vibration` andA to secure a like function with respect to the nuts.

As is well known, bolts and nuts of the ordinary kind are subjected to material vibration owing to the jar incident to the travel of trains over the same. I provide a bolt of a novel construction wherein the head cannot be burst off. The bolts I prefer to make of iron to fit into fish-plates `of like material, so as to add to the effectiveness of the oint.4 The latter is simplein construction and can be inexpensively made. As a matter of fact, the expense attending its manufacture is practically the same as that accompanying the production of a rail-joint of the common form.

In the drawings accompanying and forming a part yof this specification I illustrate a certain arrangement of parts embracing my invention which I will set forth in detail in the followin description g but Ido not restrict myselfig to the precise disclosure thus made, for material and divers variations may be adopted within the scope-of my invention l tion being taken throu h the perforations in the fish-plates and we of a rail, through Which perforations a bolt extends, the latter being in elevation. Fig. 4. is an inside face shown two abutting or substantially' abutting rails, each being designated by 2 and ble'- ing` of the ordinary construction. Extending across the joint between the rails and iitting against the opposite faces of the webs of said rails I represent two fish-plates, each designated by 3. The fish-plates and webs of the rails have registering perforations to receive bolts, as 4, the nuts of the bolts being designated by 5. The nuts may either bear against the inner or outer fish-plates, as individual preference may dictate. They are represented as abutting against the outerfish-plate. 1 The iish-plates `and *nutsv have their opposing or enga ing surfaces roughened to prevent vertica motion of the nuts when they are'set up. This roughening may be secured in any desirable way-for example, by corrugatin the said opposing surfaces. The outerv sh-plate 3 is represented as having on its outer surface longitudinal corrugations which produce, as will be evident, alternate beads and channels, while the nuts have on their inner surfaces similar corrugations. When the nuts are set up solidly in place, the `beaded or salient portions thereof will fit solidl and iirlmly i-nto the channels or grooves in t e iish-plate, so as to prevent =motion of the nuts, and this relation is asof each bolt 4 opposite that havin the externally-threaded surface is provi ed with a head, as 6, serving as' an operating-head and `which is of such a shape as to receive an imi glement for driving the bolt home.v

The eads are'shown as polygonal, a s uare shape being a satisfactory one, so that t ey can be set by an ordinary Wrench used by trackmen.

It will be seen that the heads 6` areA of less diameter than the greatest diameterof the respective tapered portions 7, whereby the ad Tvantages herein set forth for said vbolts are' assured. From this it will be evident that IDO IIO

said heads can, should' occasion require, en-

tapered portions 7 iit. It may be necessary for the heads to enter, these openings or holes when the latter are worn away, as would be the'case with old fish-plates, to 'which I 'can successively adapt my joint. Even with new plates it might be necessary for the heads 6 to enter said openings, so that in any case I can set'the nuts 5 up and do this simply by turning the bolts through the agency of their heads without touching the nuts. By virtue of the construction of the heads theydo not engage the fish-platel so that there is no possibility of the heads being stripped off, as is a' common occurrence in those bolts the heads of which abut against fish-plates. Between the head 6 and externally-'threaded portion of each bolt Vthere is a tapered surface 7, such surface, as will be evident, tapering inward from the head toward the threaded end of -lwill be drawn inwardly solidly against the i fish-plate and to such an extent that the nut andv bolt will be prevented fronrvibration, even though the engaging surfaces of the nut and fish-plate be plain.

" the outer fish-plate.

A i 6 of the bolts wil inward until they are in the iirrnest possible In operation the rails 2 will be laid in the customary manner, and the fishplates 3 will be placed against the opposite faces of the webs of the two abutting rails to bring the perforations of the fish-plates. in register with those in the webs, followingwhich the threaded ends of the bolts will be passed through the registering perforations from the inner side of the joint` The bolts, as will be understood, will extend entirely through said perforations, so as to cause their threaded ends to project beyond the outer face of the outer fish-plate 3. When this is done, the nuts 5 will be applied to the projecting ends of the bolts and turned thereu on until they strike n Fo lowing this the bolts will be drawn back slightly until the projecting portions of the corrugated surfaces of the nuts enter the channels of the corrugated surface of the iishlate. After this the head lgbe engaged by wrenches and turned, and as they are turned they are advanced, while the nuts 5 are drawn further solid relation with the outer fish-plateQ As the bolts are set, the tapered surfaces 7 therey of will solidly engage the walls of the perforations in the inner fishplate, so that when the-bolts are finally set they, as well as the nuts, are immovably held in osition.

j I have described in detai the manner of. making a joint and have set forth that the bolts are assed through the perforations in the fish-p ates and rails from the inner side of the latter. The operation can as well be reversed, as willbe gathered from what I have hereinbefore stated. While the nuts and bolts are held immovably, the outer iishplate by virtue of its engagement with the nut and the inner iish-plate by reason of its engagement with the tapered surfaces of the bolts will be equally Jfirmly held in operative position. In prac-tice the perforations through the webs of the rail will be made of slightly-greater diameter than those in the fish-plates, so as to permit of jthe contraction and expansion of the rails without affecting the relation of the bolts, nuts, and fish-plates. 'The corrugations upon the outer lish-plate, or they may be uponthe inner one, as will be understood from what I have hereinbefore stated, are directly formed therein, and they can be rolled in the fish-plate while the latter is being made. The same applies to the corrugations upon the nuts. As the corrugati ons are directly upon the fish-plates and nuts, I provide a structure that is simple.

When a bolt 5 is set, the tapered surface 7 thereof will be wedged against the wall of a perforation in the cooperating fish-plate, so asv to precludepossibility of movement of the bolt.

Not only do I hold each bolt firmly in place with a wedge-like action, but I secure the same result by the form of the joint illustrated with respect to the nuts and the cooperating fishplate. ent instance by the corrugations upon the nuts and cooperative fish-plate. The corrugations may be of any suitable character but they are represented as angular in cross-section. The outer extremities of the proj ecting portions are shown as blunt or truncated, so that when the projecting portions of a nut are fitted in the channels of the fish-plate they cannot strike the bottoms of said channels, by virtue of which when the nuts are 'Ihis result lI accomplish in the pres- IOO scribed wedging action at the several places indicated.

Having thus described my invention, what I claim is l.
