Application filed July 18, 1888. Serial No. 280.307. (No model.)

To all whom ib may concern:

Be it known that I, Arthur J. Moxham, of Johnstown, in the county of Cambria and State of Pennsylvania, have invented a new and use5 ful Method of Rolling Slot-Rails for Cable Railroads, which invention is fully set forth and illustrated in the following specification and accompanying drawings.

The object of this invention is to obtain io slot-rails which can be readily laid in the roadbed so that their opposite inner edges shall be absolutely parallel.

The invention will first be described in detail, and then particularly set forth in the 15 claim.

In the accompanying drawings, Figures 1, 3, and 5 illustrate in cross-section what may be termed the “ blanks” in each case of a pair of slob-rails, each pair having a different shape 20 of cross section; and Figs. 2, 4, and 6 illustrate each a pair of said rails after said blanks have been severed, as will be hereinafter particularly described.

In said figures the several parts are indi25 cated by descriptive letters as follows:

The letter A indicates the rolled blank in Fig. 1, consisting of the two side rails, B C, united by a web or junction-strip, a. In Fig. 2 said web a has been cut away, severing the 30 two sides B C, leaving them to present perfectly symmetrical inner sides to form the slot 0 between them.

In Figs. 3 and 4, D indicates the blank; d, the web uniting its sides; EandF, the severed 35 sides or rails; and 0, the slot between said rails.

In Figs. 5 and 6, G indicates the blanks; g, the web uniting its sides; Hand I, the severed sides or rails, and 0 the slot between said rails.

The method of forming these rails consists 40 in rolling two rails together as one piece, as indicated by Figs. 1, 3, and 5, and afterward severing them mechanically by any suitable means by cutting away the metal indicated in said figures by the letters a d g. Such metal forming a web or junction-strip is preferably 45 rolled thinner than the rest of the form, as indicated in said figures, slight variations in distribution and thickness of metal beingshown at a, d, and g, respectively. While such reduced thickness is preferable, manifestly it is not 50 essential or necessary to the invention.

The great need with all slot-rails—the important feature to be secured in laying them in the road-bed—is that their opposite inner edges shall be absolutely parallel. In this in- 55 vention this essential is readily secured, without which such necessary parallelism is very difficult to obtain, even with the utmost care in laying the rails in the road-bed. By this method not only are the two opposite rails 6c rolled together, but they are or can be straightened together before being severed, so that even any irregularity in the rolling cannot interfere with the necessary parallelism of the two rails when finished for the road bed, and 65 whatever such irregularity might be it could not exceed such as would or might also exist under the best conditions of rolling possible.

I do not confine my invention to the special forms of slot-rails shown, as it is evident that 70 slot-rails of many and varied forms of cross-sections may be rolled in integral pairs and then severed, as hereinbefore described for the forms shown in the drawings.
