WILLIAM w. RILEY, or BROOKLYN, N. Y., ASSIGNOB or ONE-HALF OF HIS RIGHT TO FRANCIS A. BAR'IHOLOMEW, OF BLOOMFIELD, N. J.

SWITCH FOR ELEVATED RAILROADS.

SPECIFICATION forming part of Letters Patent No. 227,996, dated May 25, 1880.

Application filed April 20, 1880.

To all whom it may concern! Be it known that I, WM. WILLSHIRE RI- LEY, a citizen of the United States, residing in the city of Brooklyn, Kings county, and

State of New York, have invented certain new and useful Improvements in Switches for Elevated Railroads, of which the following is a specification.

The object of this invention is to provide a simple, safe, and convenient means for switching upon elevated railroads, and specially adapted to that class of elevated railroads where a central rail and two guard or guide rails are used, such as shown in patents granted to me in 1876, numbered 173,240 and Myinvention consists in having a section of the elevated railroad constructed and arranged so that it may be swung to and from the main to the side track by having one extremity thereof supported upon a substantial butt by a heavy pintle rigidly attached to its extremity, and in having the opposite or traveling end provided with friction-rollers which bear 2 5 upon the upper surface of a suitable bedplate supported on bracketsor braces from the posts or columns, and in having the guard or guide rails supported at their respective ends by fixed brackets or braces under the same, so as 0 to prevent all possibility of swaying or of the side rails deflecting at the joint with the weight of the passing train.

Figure 1 represents a side elevation of my improved switch. Fig. 2 is a plan of the same, 3 5 showing the switch set to the main track. Fig. '3 is an end view, showing the bed-plate for supporting the traveling end of the switchsection. Fig. 4 is an end view of the traveling end of the switch, showing position of 40 rollers.

Similar letters of reference indicate corresponding parts.

In the case here presented, A represents a girder, and B B two guards or safety guide- 5 rails, which are rigidly attached to and supported from the same by a series of A frames or braces, O C O, the whole forming a com- (N 0 model.)

%1ete section or span between the columns E is a heavy pintle, rigidly attached to the girder A. This pintle is made or provided with two collars, F F, and extends vertically through bearings G G on the butt or bracket H. This pintle is made of sufficientlength to insure perfect. steadiness to the switch structure; but in order to prevent the possibility of deflection of either of the extremities of the safety guide-rails I have provided a bearing,

I, for the support of the joints.

The opposite or traveling end of the switch isprovided with two or more friction-wheels,

J J, which are housed, and have their bearin gs in the A-frame at its extremity, and which bear upon the plane of the are or bedplate L, connecting the columns between the main and side track.

It will be observed that the extremity of the girder which abuts against the main central rail is made convex, so as to match the concavity at the extremity of the fixed girder, and in order that the extremities of the guard or safety guiderails of the switchsection shall always remain in close contact with those of the main line, they are cut and set radial to the pintle E, and provided with wings KK at their extremities, so as to make the safetyguide continuous whether set for the main or side track.

Having thus described my invention, what I claim as new, and desire to secure by Let- 8o ters Patent, is- I In an elevated railroad, the combination of the independent swinging section A B G, having pintle E and friction-wheels J J, with the fixed butt H, side wings or brackets, I I, and the supporting-arc L, rigidlyattached to the columns, the whole being constructed, arranged, and operating together in the manner and for the use and purpose specified.
