4 Claims, 6 Drawing Figures 1 ELECTRO-MAGNETIC RAILWAY TRACK BRIEF SUMMARY OF THE INVENTION In the present practice of railroading in a switch yard, a locomotive pushes a column of freight cars over an elevated track over a mound or hump and they are permitted to coast unattached down an incline to be allocated into trains. A brakeman rides on each car with a lever or similar device held in the brake hand wheel on the roof of the car to slow the progress of the car down the incline and as it approaches the previously allocated cars in the train for attachment or coupling thereto.

The present invention will enable a tower man to operate switch levers to energize electro-magnetic means in portions of the track rails to slow or stop the cars.

DETAILED DESCRIPTION and 16 which may lead to switches (not shown) in a The need for a brakeman to ride on each individual car is thus eliminated. In the big railroad yards the tower men operate retarders to control the cars. Workers who are designated as skate men place the skates to stop the first car dispatched in an allocatedgroup. The present invention would obviate the need for skate men.

BRIEF DESCRIPTION OF THE DRAWING FIG. 1 is a view in elevation of a rail provided with subjoined electro-magnetic means in one form of the invention.

FIG. 2 is a cross-sectional view taken on line 2,2 of F IG. 1.

FIG. 3 is a view in elevation showing magnetic means secured to the web of a rail.

FIG. 4 is a cross-sectional view partly in elevation.

FIG. 5 is a view in elevation of a rail provided with non-conductive insulating means and an elongated subjoined magnetic plate provided with individual or multiple electromagneticinstallations.

FIG. 6 is a cross-sectional view of the rail and the subjoined plate coextensive with the transverse dimension of the rail base.

switch tower (not shown). FIG. 4 illustrates the lateral placement of the electro-magnetic means.

In FIG. 5, a rail 17, which may be adapted to be magnetized is spaced from the rest of the track by means of non-conductive or insulating elements 18 and 19 and has an elongated electro-magnetic bar 20 underlying the base'21 of rail 17 and transversely coextensive with said base 21.

In use, in the hump operation before referred to, a string of cars can be pushed over the elevation to coast downwardly without brakemen riding on each car.

The tower man can manipulate track switches to allocate each car to its proper train. He can also use switches to energize electro-magnets to slow and also stop and hold the cars.

Having thus described the invention, what is claimed and desired to be secured by Letters Patentof the United States, is:

l. A length of conventional track rail isolated from rails on either end by non-conductive spacers and adapted to be electro-magnetized by any appropriate means. A

2. A device as in claim 1, including electromagnet means subjoined to the base of the rail.

3. A device as in claim 1, including multiple electromagnetic installations subjoined to the base of the rail I and wired in parallel.

4. A device as in claim 1, and electro-magneticmeans attached laterally of the rail web.

Claims (4)

1. A length of conventional track rail isolated from rails on either end by non-conductive spacers and adapted to be electromagnetized by any appropriate means.

2. A device as in claim 1, including electromagnet means subjoined to the base of the rail.

3. A device as in claim 1, including multiple electro-magnetic installations subjoined to the base of the rail and wired in parallel.

4. A device as in claim 1, and electro-magnetic means attached laterally of the rail web.
