runners M.- 'RANDELL, or GREENBUZRG'QNEW YORK.

Letters Patent No. 110,868, dated January it, 1871.

l'he Schedule referred to in these Lotta-[Fatwa and at the name.

To all whom it may concern Beit known that I, FRANCIS M..Rstmnnn, of the town of Greenburg Westchester county, State of New York, have invented a new and improved Apparatus for Supplying Na'phtha to Vapor-burning Street- Lamps; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being. had to the accompanying drawing forming part of this specification.

Figure 1 is a central vertical section of my invention.

The object of my invention is to place in every separatelamp-post, or adjoining thereto, a tank containing.

sufiicient naphtha or gasoline. to supply a burner for one or more weeks by placing the liquid in the base or lower part 'of the lamp-post, or in a separate tank buried in the ground adjoining the lamp-post and connected therewith by proper supply-pipes. The liquid,

I raise to the burner by compressed air contained in the naphtha-tank.

Hitherto the liquid has been supplied to vapma burning strectdamps by'elevating the naphtha-tank above the flame,and the required pressure has been obtained by the falling column of liquid. The small quantity'of naphthaoontaiued in a tank thus arranged requires the supply to be almost daily replenished. Thelabor and expense of the repeated refilling of the naphtha-tank is a great drawback to the use of this method of street-lighting. L

My improvements are intended to remedy these defects, and are carried out as is hereinafter more fully set forth.

In the drawing- 'A is the tank or reservoir formed in the base of the lamp-post. This tank is supplied with gasoline by forcing the liquid down through pipe 0. The airin the upper part of the tank becomes compressed in proportion to the pressure put upon the liquid forced into it. The accumulated air-pressure drives the naphtha up pipe' 0 to the burner; In thisway pipe 0 serves both as i'eetly air-tight joint.

To fill the tank, I conduct. naphtha under pressure, by means of a suitable pipe, from a reservoir to the inlet-cock Gr.-- When thisjcock is open theliquid will flow into tank A from the reservoir until the pressure in the tank and reservoir is equalized. The fillingcock is then closed and the lamp is ready for-lighting.

Tb prevent the naphtha being stolen or tampered with,1 make the cock G so that it can be turned only;

by a certain key kept in the possession of the lamplighter. v 4

Having now described my invention, and the manner of putting the same in operation, I woulll have .it

distinctly understood that I lay no claim to any of the parts separately except for the purposes of my invention.

'I claim- T The combination, with a street lamp-post, of the naphtha-reservoir, pipe, and cooks, for the purpose of filling the reservoir with naphtha and supplying the latteuto the burner -under pressure, as described.
