nuisances referred to in these 1mm- Patent a d making part of the am.

To all whom it may concern:

Be it known that I, James J. Jonns'ron, of the city and county of Allegheny, in the State of Pennsylvania, have invented a new and useful Improvement in Apparatus for Distilling Hydrocarbon-Oils; and I do hereby declare that. the follow-ing is a full, clear, and exact description thereof, reference being hadto the accompanying drawings, and to the letters of reference marked thereon,

The nature of my invention consists in distilling hydrocarbon-oils by distributing them, through the medium of a pipe, in small streams, or jets against the inner surface of a revolving still, in which is placed a shaft, armed with' a spiral flange, so arranged and operated that it will force the vapor evolved from the hydrocarbon-oil from the still into the condenser.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

In the accompanying drawings, which form part of my specification- Figure 1 is a side view of my improvement in apparatus for distilling hydrocarbon.

Figure 2 is a longitudinal section of ,the same.

In the drawings- A represents a furnace, which may be constructed of sheet-metal or other suitable material.

B represents the stack of the furnace.

0 represents the fire-door.

9 represents a cylindrical still, one end of which is made coniformed, as shown at a.

The still 9 is provided with two hollow trunnions,

D and D, which have suitable bearings'in the eud-- walls of the furnace.

It represents a hollow drum, or shaft, provided with a spiral flange, i, which flange should be made snfliciently wide, that by the revolving of the shaft h, the wings, or flange i will force out, through-the hollow trunnion D, into the condensing-device, the vapor evolved in the still g.

' The end, 0, of the hollow shaft h is supported, and revolves within the trunnions D, and is provided with a pulley, f, for revolving it.

The end, e, is supported, and revolves in the crossbar J, the ends of which are secured to the sides of the still g.

The hollow trunnion D of the still g is fitted into the end of a pipe, as indicated by the dotted lines I, which pipe is to be connected with the condensingdevice, which may be constructed in any of the known forms.

Through the pipe I, and through the hollow trim-- vided with a series of small holes, for the purpose of distributing the hydrocarbon-oil evenly, and in small streams on the sides of the still g.

The pipe k is to be attached to a reservoir for holding the hydrocarbon-oil, and, at some suitable point between saidreservoir and the pipe I, should be provided with a suitable valve for regulating the flow of oil through the pipe it, into the still g.

From the foregoing description, and by reference to i the accompanying drawings, the skilful mechanic will readily understand the construction of my improvement inapparatus for distilling hydrocarbon-oils, and

-the relation that the several parts of said apparatus 1:, into the still, in small jets or streams, which must be in proportion to the capacity of the still to evolve the oil into vapor. The small jets or streams, falling on the side of the still, will be, by the revolving of the still, spread in a thin sheet over the inside surface of the shell,.or sides of the still, thereby exposing, to the action of the heat, a very thin, and continuous sheet of the hydrocarbon-oil, which will readily be evolved into a vapor, which, by revolving the shaft it, will, through the mediumof the spiral wings, or flange i, be forced from the still g, through the hollow trunnion D andpipe 1, into the condenser.

The o'il, after being distilled, maybe separated from its benzole, and treated and manipulated in any of the known methods.

Having thus described my improvement,

What I claim as of my invention, is-

1. Distilling hydrocarbon-oil by distributing it, through the medium of a pipe, in small jets or streams, against the inner surface of a revolving still, in which is placed a revolving shaft, armed with a spiral flange, so arranged that it will force the vapor evolved from the hydrocarbon from the still, into the condenser, as hereinbefore described.

2. The combination and arrangements of the still g, provided with the hollow trunnions D and D, the shaft It, provided with flange, or Wings 1', and the pipe k, constructed, arranged, and operating substantially as herein described, and for the purpose set forth.

JAMES'J. JOHNSTON.
