ARTHUR J. MOXHAM, OF JOHNSTOYVN, PENNSYLVANIA.
SPECIPICATTON forming part of Letters Patent No. 388,995, dated September 4:, 1888.
(No model.)
To aZZ whom it may concern:
Be it known that l, ARTHUR J. hIOXl-IAM, of .l'ohnstown, in the county of Cambria and State of Pennsylvania, have invented a new and useful Method of Rollin g 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 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 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 slot-rails, each pair having a ditferent shape 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 parlicularl y described.
In said figures the several parts are indicated by descriptive letters as follows:
The letter A indicates the rolled blank in Fig. 1, consisting of the two side rails, B G, united by a web orjunction-strip, a. In Fig. 2 said web (L has been cut away, severing the two sides B O, 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; E and F, the severed sides or rails; and 0, the slot between said rails.
In Figs. .3 and 6, G indicates the blanks; g, the web uniting its sides; H and I the severed sides or rails, and 0 the slot between said rails.
The method of forming these rails consists 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 11 9. Such metal forming a web orjunction-strip is preferably rolled thinner than the rest of the form, as in dicated in said figures, slight variations in distribution and thickness of metal being shown at a, d, and g, respectively. \Vhile such reduced thickness is preferable, manifestly it is not essential or necessary to the invention.
The great need with all slot-railsthe important feature to be secured in laying them in the road-bedis that their opposite inner edges shall be absolutely parallel. In this invention this essential is rcadilysecurcd, 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 rolled togeth or, but they are or can be straightened together before being severed, so that even any irregularity in the rolling cannotinterfere with the necessary parallelism of the two rails when finished for the roadbed, and 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 slot-rails of many and varied forms of cross-sec tions may be rolled in integral pairs and then severed, as hereinbefore described for the forms shown in the drawings.
Having thus fully described the nature and advantages of my said method of rolling slotrails, as of my invention I claim- The method of rolling slot-rails for cable railroads, consisting in rolling a pair of such rails integral as one form and then severing such form into two rails, substantially as and for the purposes set forth.
