To all h it y ri 1 tion is applied. Neither do I wish to be lim Be it knownthat I, EDWIN-O. BRUEN, a ited to any particular means of fastening the] citizen of the United States, and a resident of rails to the ties Cir-sleepers. I have found, Brookl'yn,in the county of Kings and State however, that the'form ofrails and method of 6c of New York, have invented certain new and fastening them shown the drawings is useful Improvements in Inclined Railways, cheap and efficient. of which the following is a specification. In order to lower the temperature of the My invention relates to improvements in rails to a freezing-point, I circulate through inclined railways, and particularly to an inthem a supply of cold air .or freezing gas or 6; cline railway upon the rails of which a coatfiuid by means of a suitable pump, and in or-' ing or layer of 106' of any desired thickness der to do this effectively and economically I may be formed at any time by artificial arrange suitable return-pipes (not shown') means. connecting with the rails at theend of the The main object of my invention is'to prochute or slide.

In Fig. 4 o the drawings I have shown a group or series of pipes K, arranged side by side and preferably united by T connections and provided with a branch ipe K, from Whic the ipes constituting tl fe rails B may extend. hese pi es K are to be provided with the non-conductor F and waterproof material G, which may be arranged and a lied as described with reference tothe rails or the pipes K may be embedded in the The object of non-conducting material.

this construction is to have a starting-plat- I form for the tobog ans which may at any time be rovided wit a layer or coating of ice of any esired thickness by the same means and in the manner described for the rails. It is obvious that any desired'number of these pi es K may be employed.

llVhat I claim as new, and desire to secure by Letters Patent, is-

1. An inclined ice-railway consisting of two or more exposed hollow rails having their u per surfaces coated with ice to form a c ute,. substantially as and for the purposes set forth.

2. An inclined ice-railway, consisting of two or more hollow rails, and means for forming a layer or coating of ice directly upon the upper surfaces thereof.

3. A toboggan chute or slide consisting of two or more hollow rails, said rails having a layer or'coating of ice formed directly upon their up er surfaces by the action of a'freezing me ium circulating through said rails upon liquid or moisture de osited thereon, substantially as described. or the purposes set forth.

4. An inclined. ice-railway consisting of two or more hollow rails, said rails having a ing me ium circulating through said rails I upon liquid or moisture deposited thereon,

and means for de ositing a sup ly of liquid upon the rails, su stantially as escribed.

5. An inclined ice-railway consisting of two or more hollow rails, and means for forming a layer or coating of ice upon the upper surfaces thereof, said rails being provided on the lower surfaces with a covering of nonconducting material to prevent the formation of ice upon such portions, substantially as described.

6. An inclined ice-railway consisting of two or more hollow rails having a convex icesurface formed upon the upper surfaces of said rails, substantially as described.

7. A platform for an inclined railway consisting of a group of pipes, and means for forming a layer or coating of ice upon the upper surfaces thereof, said pipes being provi ed on the lower surfaces with a covering of non-conducting material to prevent the formation of ice upon such portions, substantially as described.

8. An ice-platform consisting of a series of pipes, and means for forming a layer or coating of ice upon the upper surfaces thereof, said pipes being provided on the lower surfaces with a bed or covering of non-conducting material to prevent the formation of ice upon such portions, substantially as described.

Signed at New York city, in the county of New York and State of New York, this 8th day of March, A. D. 1906.
