MOVABLE-POINT RAILWAY-CROSSING.

Specification of Letters Patent.

Application filed November 10, 1905. Serial No. 286.710-

Patented Feb. 13, 1906.

To all whom it may concern:

Be it known that I, FRANK L. KEIM, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Movable-Point Railway- Crossings, of which the following is a specification.

The object of my invention is to prevent the rapid wearing away or grooving of the stock-rails on this type of crossing, and this object I attain by making a substantial section of hard material, such as manganese steel, which will not only increase the life of the crossing parts, but will also strengthen the structure. This I accomplish in the following manner, reference being had to the accompanying drawings, in which- Figure 1 is a plan view of my improved movable point crossing. Fig. 2 is a detached perspective view of one of the stockrails. Fig. 3 is a sectional view on the line 3 3, Fig. 1; and Fig. 4 is a sectional view on the line 4 4, Fig. 1.

A A are the rails of the main track.

B B are the rails of the crossover-track.

a a and b b are the movable points. The points a and b are connected by tie-rods c, and the points a and b are connected by tierods 0, and these point-rails are moved by the lever E, having arms 6 6, connected by rods 6 e to the tie-rods c and 0, respectively, and the lever is actuated by any means desired.

D D are the hard-metal stock-rails having wide heads to receive the full tread of the car-wheel and made of metal hard enough to prevent the falseflanges of the hollowedout worn wheels under heavy trafiic cutting into the surface. These stock-rails are preferably made of manganese steel.

The stock-rails are shaped to the desired angle and recessed at each end at d for the reception of the ends of the adjoining rails of the tracks. The ends of the stock-rails are inclined at d d, so as to lift the overhanging tread of the car-wheels up onto the head of the stock-rails, and these ends also serve to rigidly connect the adjoining track-rails to the stock-rails, bolts or other fastenings being used with or without the usual fish-plate.

The base of the stock-rails D D may be flanged, as shown in the drawings, and be fastened to the ties in the same manner as heavier than the ordinary rails they make a very strong and substantial crossing structure. 1

In some instances the movable-point sections (1 a and b b may also be made of hard metal, such as manganese steel, and be secured to the track-rails in any suitable man ner.

I claim as my invention 1. A movable-point railway-crossing having a stock-rail with an extension at each end forming a recess at each end for the reception of the respective adjoining track-rails, substantially as described.

2. A movable-point railway-crossing having a stock-rail with a wide head and with an extension at each end forming a recess at each end for the reception of the respective adjoining track rails, substantially as described.

3. A movable-point railway-crossing having a stock-rail made of hard metal with an extension at each end forming a recess at each end for the reception of the respective adjoining track-rails, substantially as described.

4. The combination in a movable-point railway-crossing, of hard-metal stock-rails shaped to the angle desired and recessed at the ends so as to be coupled in line with the adjoining rails of the track, with movablepoint rails, and means for shifting said pointrails to and from the stock-rails, substantially as described.

5. The combination in a movable-point railway-crossing, of the track-rails, stockrails one at each side of the track arranged to aline with the track-rails and shaped to the angle desired, movable point rails, and means for shifting the said point-rails to and from the stock-rails, the said stock-rails having an extension at each end forming a recess at each end for the reception of the respective adjoining track-rails, the ends of said extensions being beveled, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

FRANK L. KEIM.
