UNITED STATES PATENT O F C ALBERT MARION GRUBBS, OF CEDAR RAPIDS, IOW'A RAI LWAY-FROG.

SPECIFICATION forming part of Letters Patent No. 436,906, dated September 23, 1890.

Application fil d December 13, 1889. Serial No. 333,580. (No model.)

To all whom it may concern.-

Be it known that I, ALBERTMARION (humans, a citizen of the United States, residing at Cedar Rapids, in the county of Linn and State of Iowa, have invented a new and useful Rail- Crossing, of which the following is a specification.

This invention relates to railroad-frogs; and it consists in the improved construction and arrangement of parts, which will be hereinafter more fully described, and particularly pointed out in the claims.

In the drawings, Figure 1 is a plan view of the frog, diagrammatically showing the position of a car-wheel in passing over the continuous rail of the main track at the frog. Fig. 2 is a transverse sectional view taken on Fig. 3 is a perspective detail View showing a portion of the mainline rail and the elevated rail located adjacent thereto. Fig. 4 is a perspective view of the railroad-chair used in connection with my invention.

Like numerals of reference indicate like parts in all the figures.

l and 2 designate, respectively, the outer and inner continuous rails of the main track.

3 is the inner and 4 the outer siding-rail, the former of which joins the inner main-line rail at 5.

At the point 5, Where the inner switch-rail 3 joins the inner main-line rail 3, is located a raised or elevated rail 6, which has an outwardly-turned terminal end 7, and Which for a portion of its length is parallel to the said main-line rail 2 and only at a sufflcient distance from the latter to admit of the passage relation to each other. A portion of the head of the outer side of the main-line rail 2 is removed, as will be seen at 15, so as to enable the Wheels traveling to or from the switchtrack to get a full tread upon the elevated rail 6 when about to cross the main-line rail 2, as will be seen most clearlyin Fig. 2 of the drawings.

The operation and advantages of my invention will be readily understood from the foregoing description, taken in connection with the drawings hereto annexed. When a train approaches the frog, the treads of the wheels will ride upon the elevated rail, which is sufficiently raised to prevent the flanges of the Wheels from coming in contact with the mainline rail, the head of which is, moreover, cut away, as shown, to avoid contact With the wheel-flanges. The transfer of the wheels across the mainline rail is thus easily and safely accomplished.

It will be seen that by my invention a frog is provided, by means of which all necessity is avoided for cutting or severing the mainline rails, thereby reducing or avoiding the danger of cars leaving the track. All jolting is also prevented, thereby preserving the roll-' ing-stock from injury, and inasmuch as the car-wheels or the flanges of the same do not come in contact with the main-line rails at the points of crossing the said main-line rails are preserved from excessive wear.

I claim- 1. The elevated rail forming a portion of the inner siding-rail terminating adjacent to the inner side of the inner main-line rail and having its ends inclined downwardly to a level with the main-track rails, in combination with the inner main-line rail having a portion of its head removed on its outer side, substantially as set forth.

2. The elevated rail forming a portion of the inner siding-rail and terminating adjacent to the inner side of the inner main-line rail, in =1 combination with the inner main-line rail having a portion of its head removed on its outer side, substantially as set forth.

3. The combination of the main-line rails 1 2, the latter having a portion of its head removed on its outer side, the siding-rails 3 4, my own I have hereto affixed my signature in the elevated rail 6, having the outwardlypresence of two Witnesses.

turned end 7, said elevated rail being placed 1 parallel to the inner maimtrack rail, and the ALBERT MARION (IRUBBS' 5 guard-rail 10, substantially as and for the pur lVitnesses:

pose set forth. WM. BAGGER, In testimony that I claim the foregoing as J. H. SIGGERs.
