ASSIGN OR TO MASSACHUSETTS CORPORATION OF MAINE.

INTERCHANGEABLE TURNOUT FOR RAILWAYS.

SPECIFICATION forming part of Letters Patent No. 723,300, dated March 24, 1903.

Application filed April 5, 1902 I To all whom it may concern.-

Be it known that I, DAVID E. PEPIN, a citizen of the United Statesganda resident of Ware, in the county of Hampshire and State 5 of Massachusetts, have invented certain new and useful Improvements in Interchangeable Turnouts for Railways, of which the following is a specification.

In the usual method of constructing turn- [0 outs the casting which is included in the mate has formed integral therewith a railsection which forms a part of the main track, and the main rail has thereforetlo have a section cut out in order to allow its insertion.

portion cut out, and if for any reason the location of the turnout is changed it necessitates insertion of another short section of railto complete again the main line. Another and very serious diszoadvantage of this is that it makes short joints, it beingan advantage to have the fewest possible number of joints in the track.

The object of this invention is to provide such a form of mate that it can be connected I at any part of the main line where desired and to utilize as a part of the combination those portions of the main rails which would ordinarily be cut off.

The invention will now be fully described by reference tothe accompanying drawings, and the novel features thereof will be particularly pointed out in the claims at the close of the specification.

In the drawings, Figure 1 is a diagrammatic view of a section of railroad and turnout, illustrating the invention. Fig. 2 is a plan, partly in section, showing the mate and its connection with the rails.

Referring now tothe drawings, 1 and 2-represent the two lines of rails forming the main track, and 3 at represent the two lines of rails of the turnout.

The mate consists in part of a long casting 5 the whole length of one side of which lies up againstwthe web of the main rail 1 and the other side of which tapers for a part of its length, forming a somewhat wedge-shaped portion 5, which lies between the web of the main rail 1 and of the turnout-rail 3. The casting is formed with a shoulder 6 at the end the turnout-rail.

of the wedge portion 5 in front of the end of On the inner side of the turnout-rail 3 is a fillet 7, which fits up against the web of the rail 3 and the end of which makes a joint with the shoulder 6. 9 extends alongside of the fillet 7 and the for- .ward portion 8 of the casting. The guard 9 is a piece of fiatsteel. Bolts 10 pass through the guard 9 and the main rail 1 and all intermediate membersthat is, at the wider portion they pass through the guard 9, fillet 7, turnout-rail 3, casting 5, and main rail 1. At the narrower portion they pass through the guard, casting, and main rail.

Turnouts constructed according to the invention can be built much more cheaply and with less labor than when the main rail has to be cutout to admit the ordinary special work, as heretofore done, and relocation of the turnout can also be much more economically made. Moreover, it obviates the necessity of short joints in the main track,which are very objectionable.

What I claim is- 1. In a turnout for railways, in combination with a main rail and a turnout-rail, a casting having a wedge-shaped portion between the main rail and the turnout-rail, a shoulder at the tapered end of the wedge-shaped portion which projects in front of the turnout-rail, an extension of the casting which lies against the web of the main rail, a casting which lies against the turnout-rail on the opposite side from the wedge-shaped portion, and which extends to said shoulder, and bolts which secure the castings and the rails together, substantially as described.

2. In a turnout for railways, in combination a main rail, a turnout-rail, a fillet, a casting between the main rail and turnout-railand extending beyond the end of'the turnout-rail alongside of the fillet and the extension of the casting, all of said parts being secured together by bolts, substantially as described.

In testimony whereof I have affixed my signature in presence of two witnesses.
