RAIL-JOINT.

SPECIFICATION forming part of LettersPatentYNo. 602,102, datedv A .pril 142, 1898.

Application filed August 16 1 8 7.

To all whom t may concern.-

Be it known that I, THEODORE F. PHILIPPI, a citizen of the United States, residing at St. Louis, State of Missouri, have invented certain new and useful Improvements in Rail- Joints, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

My invention has relation to improvements in rail-joints; and it consists in the novel construction of joint to be more fully set forth in the specific-ation and pointed out in the claims.

In the drawings, Figure 1 is a side elevation of my joint as applied to two adjacent rails. Fig. 2 is a section on line .n of Fig. l. Fig. 3 is a section on line y'y of Fig. 2, with the rails, however, in elevation. Fig. 4 is a transverse section on line z z of Fig. l. Fig. 5 is a detached view of the locking-key.

. Fig. 6 is adetached view of the split pin carried by the key, andFig. 7 is a detailrend view of the key with the pin inserted.

The object of my invention is to construct a rail-joint which While it subserves the purpose of a fish-plate at the same time serves as a bond which willdraw the adjacent ends of the rails into close proximity to one an-V other and to the bottom of the casing, which form the present construction of joint assumes.

A further object is to provide a joint which will be simple, inexpensive, and durable.

In detail the invention may be described as follows:

Referring to the drawings, l 1 represent two contiguous rails, the lower flanges and webs of which are embraced by the walls of the casing 3, constituting the rail-joint, the rails being inserted into the open ends of the casing from opposite sides. The cross-section of the casing conforms substantially to .that of the web and lower iange of the rail, as best seen in Fig. 4, the vertical walls of the casing snugly embracing the adjacent surfaces of the web. The adjacentends of the webs of the rails are provided with suitable circular openings 4, with which are adapted to normally and eccentrically aline the elongated openings 5 of the vertical members or walls of the casing, the points of intersection serial No. 648,437. u0 model.)

of the peripheries of said openings on opposite sides ofthe center'of the casing being along lines or chords 6, inclined upward tof Ward the meeting ends of the railsand converging toward one another, whereby a section of metal of the web is exposed through by not only drawing the contiguous ends of the rails into close proximity, but at the samev time forcing each rail firmly against the bottom of the casing-that is to say, the rail will be drawn both horizontally and. vertically. To insure a positive bearing for the rail, I provide the inner surface of the bottom of the casing with raised ledges or .platforms 8.

After the key is driven home a split pin 9 is driven through the opening 10 at the tapering end of the key, the said pin serving to draw the vertical members of the casing close against the webof the rail. The present'casing or joint may, if made of material such as copper, serve as an electric bond for rails over which run electric or trolley cars.

Having described my invention, What I claim is l. A rail-joint comprising a casing adapted to embrace the flanges and webs of two contiguous rails, and conforming in cross-section to that of the parts embraced, and means for simultaneously drawing thecontiguous ends of the rails toward one another and also forcing said rails iirmly against the bottom of the casing, substantially as set forth.

2. A rail-joint comprising a casing adapted to embrace the Iianges and webs ,of two contiguous rails, and conforming in cross-section to that of the partsembraced, means for securing the vertical walls of the casing to the Webs of the rails, and meansv for simultaneously drawing the contiguous ends of the rails toward one another and also forcing said rails firmly against the bottom of the casing, substantially as set forth.

3. A rail-joint comprising a casing adapted to embrace the lower flanges and Webs of the adjacent ends of tWo rails, the Web of each rail'having suitable openings formed therein,

and the vertical Walls of the casing also hav-- ing suitable openings adapted to normally but eccentrically aline With the openings of the Webs, the said openings intersectingralong the ends of a chord inclined toward the free end of the rail thus leaving sections of the metal of the web exposed along a diagonal line tending toward the center of the length of the casing, a key adapted to be forced through each of the alinin g openings whereby in the driving of the key the rails are forced toward each other and at the Same time firmly against the bottom of the casing,
