RAIL-JOINT.

Application fil e cl Februar 10, 1919. Serial as. 276,220.

T 0 old whom it may concern Be it known that I, HUGH H. Soinmlit u, a citizen of the United States, and a resident of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new andImproved litailJoint, of which thefollowing is a full, clear, and exact description.

The invention relates to an improved rail joint with aself, or automatic, tightening and locking device and the object of this invention is to provide a simple and efficient device of this kind, comprising simple and practical features of construction.

Another object of the invention is to provide a device that is so constructed that it is easily applied and very diflicult to remove or tamper with, and further it requires very little more attention after it is applied.

With these and other objects in view, the invention consists of certain novel fea tures of construction as hereinafter shown out in the claim.

A practical embodiment of the invention is represented in the accompanying drawing forming part of this specification, in which similar characters of reference indi cate corresponding parts in all the views.

Figure l is a perspective view showing a portion of the ends of the rails meeting and the outside fishplate of the rail joint attaohed and also the end of the inside fishplate of the rail joint.

Fig. 2 is a view of the ends of the two rails meeting with the holes for the studs, (or rivets). I

. In Fig. 3 are views showing the outside fish plate with A an end view, and B an edge view.

In Fig. 4 are detailed views of the inside of the fishplate with the tightening and locking device.

Fig. 5 shows, side, end and edge views of the inside plate.

The rail joint illustrated in Fig. 1 is provided with two fishplates, which are connected to each other by studs A passing through the holes 11 of the rails and the apertures in the fishplates and are tightened. and locked by the wedge or key 9 shown in Fig. 4, which gradually slides in between stud A and the back wall of the recess 10. by its own weight and the spring 6, assisted by the little movement and trembling Specification of Letters Patent.

of the rails when the cars pass over them.

As shown in Fig. 5 the inner fishplate is of the common form of constructionwith a series of studs A, either fastened solid in tures in the pla-te-which are sufficiently large to permit the stud heads to pass and from these apertures extend longitudinal slots to fit the shanks of the studs 5 and by moving the studs into these slots the heads form shoulders abutting the side of the plate, thus preventing them from being withdrawn without a backward movement. This fishplate 3 has a series of wedge or inclined surfaces extending from the large openings of the apertures to the ends ofthe longitudinal slots. This fishplate 3 is also formed with an opening or recess 10 on the inner side of the plate facing the rail, this opening extending from the top of the plate downward to the bottom and from the rear or back wall of the aperture to the end of the longitudinal slots minus the diameter of 'is the spring 6.

When the plates are in position and plate 3 is moved forward and the studs enter the longitudinal slots, the key 9 passes between the stud 5 and the back wall of the opening 10 and acts as a wedge, and by the action of the spring, and its weight downward the key drives the stud 5 and the This action with the stud heads moving forward on the inclined surfaces of the plate elfect the tightening and the downward movement of the key at the same time constitutes the looking device of the invention. It will be noticed that when the key is in place and be- 1- the rails and the fishpllates, one of the fish-1 plates having "a series 'oflongitudinal'. slots. to v i receiye shanks oi the studs and to en- H Q"1,321,55s
