I RAIL JOINT.

RAIL-JOINT.

To all whom it may concern:

Be it known that I, IVIARTIN BOYER, a citizen of the United States, residing at Lowry, in the county of Pope and State of Minnesota, have invented a new and useful Rail- Joint, of which the following is a specification.

This invention relates to rail joints and one of its objects is to provide means whereby rails may be securely fastened together without the use of bolts such as ordinarily employed, the members of the joint having interlocking portions which cooperate to prevent displacement of the parts while the rail is in position and certain of the parts of the oint being designed to grip the rails in proportion to the weight applied thereto.

lVith the foregoing and other objects in view which will appear as the description proceeds the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

In the accompanying drawings the pre ferred form of the invention has been shown.

In said drawings :Figure 1 is a plan view of a joint embodying the present improvements, the same being applied to rails. Fig. 2 is a section on line AB Fig. 1. Fig. 3 is a perspective view of one of the members of the joint. Fig. 4 is a detail view of the base plate. Fig. 5 is a bottom plan view of the two rail gripping members of the joint. Referring to the figures by characters of reference 1 designates a base plate having upstanding enlargements of irregular contour such as indicated at 2, these enlargements extending across the longitudinal center of the plate and having their end portions preferably of greater width than the middle portions thereof. In the drawings the enlargements have been shown substantially of the shape of a figure 8, but it is to be understood that other shapes may be employed if so desired.

The enlarged ends of the projecting por tions 2 are adapted to fit within recesses or openings 3 formed withinthe plates 4 of the rail engaging members of the coupling, each of these bases merging into an over- Specification of Letters Patent.

hanging portion 5 from which extends afish plate 6. Braces 7 are preferably arranged upon the outer face of each fish plate and the portion 6 adjacent thereto and spike receiving notches or recesses 8 may be formed within the rail engaging portions along the sides thereof. Two of these rail engaging portions are provided, each being a duplicate of the other and the base flanges of the rails to be fastened are adapted to fit upon the bases 4 and under the overhanging portions 5, the inner or free longi tudinal edges of the base portions being normally supported out of contact with the base plate 1 but being capable of swinging downwardly when the rail is subjected to weight so as to cause the fish plates 6 to press more firmly upon the webs of the rails v interposed between them. The inner .portion of each recess or slot 3 is larger than the open end thereof and it will be apparent that, as long as the bases 4 are in engagement with the enlargements 2, they will be prevented from spreading apart. The only way in whlch these bases can be disengaged from the base plate 1 is by lifting them off of the enlargements.

In fastening rails together by means of the joint herein described, the rail ends are brought together and the bases 4 are inserted thereunder from opposite sides so as to bring the fish plates 6 against the webs of the rails. The base plate 1 is then placed under the bases 4 after which said bases are lowered into engagement with the enlargements 2 which thus constitute ties for holding the bases 4 against movement away from each other. Spikes such as ordinarily employed can then be placed in the notches or recesses 8 and driven through openings 9 formed in the base plate 1, and into the tie or ties under the plate thus securely holding the parts of the joint together. It will be apparent that whenever the rails are subjected to increased weight, they will press downwardly on the free longitudinal edges of the bases 4, thus causing the fish plates to more firmly grip upon the webs of the rails.

As heretofore stated it becomes unnecessary to employ bolts for fastening the parts of the oint to the rails, but it is to be understood that, if preferred, such bolts may be employed and for this purpose openings 9 have been formed in the fish plates 6 and are adapted to register with corresponding openings formed Within the Webs of the rails.

\Vhat is claimed is 1. A rail joint including a base plate, a tie projection thereon and extending transversely thereof, and rail engaging members detachably mounted on the base plate and having bases formed with openings for the reception of the tie projection, and rail gripping devices connected to said bases.

A rail joint including a base having an upstanding transverse projecting portion thereon and rail engaging members mounted on the base plate, each of said members including a base having an opening for the reception of a portion of the projection, and an upstanding ail gripping portion, the said bases being mounted to tilt relative to the base plate when subjected to a Weight.

3. A rail joint including a base plate, a tie projection upstanding therefrom and extending transversely thereof, said projection having enlarged end portions, and rail engaging members mounted on the base plate and oppositely disposed, each of said mem 5 bers including a base having an opening for the reception of the tie projection, and a fish plate portion for engaging the Webs of the rails mounted upon the base, said rails constituting means for forcing the bases down- 30 Wardly to bind the fish plate portions upon the rails.

4. A rail joint including a base plate, transversely extending projecting portions thereon constituting tie devices, each of said 35 projecting portions having enlarged end portions, and oppositely disposed rail engaging members detachably engaging said enlarged portions and held thereby agamst spreading apart.

In testimony that I claim the foregoing as my own, I have hereto aflixed my signa ture in the presence of two Witnesses.
