IMPROVED APPARATUS FOR CARBURETING AIR.

Specification forming part of Letters Patent No'. 57,164, dated August 14, 1866.

drawings, which are made part of this specification, and in which- Figure 1 is a transverse vertical section through the center of the machine. Fig. 2 is a vertical transverse sect-ion of the regulator at its full height. Fig. 3 is a front elevation.

Fig. 4 is a perspective view of a portion of the air-forcing wheel, showing the open end. Fig. 5 is a longitudinal vertical section of the machine. Fig. 6 is a side elevation.

The invention consists of a machine through i which a body1 of air is forced by a motor,

(weight, for instance,) and is caused to circulate against surfaces charged with hydrocarbon liquid for the purpose of carbureting it.

`The peculiar features of the machine consist- First, of an air-forcin g cylinder or chamber revolving in a tank within a revolving carburetin g-cylinder which revolves Within the hydrocarbon reservoir and carries up a portion of hydrocarbon for exposure to the air which circulates through the machine.

Second, it also consists of a regulatingchamber so placed above the machine and op erated by the iniiux of gas thereinto as to close the passage of gas from the machine and stop its operation till the pressure is relieved by removal of gas from the regulatingchamber.

Third, it also consist-s of a central displac ing-chamber placed within the air forcing cham ber and provided with radial arms which connect it with the exterior case.

Fourth, the carbureting-cylinder provided with a reticulated or permeable surface, and with lifting cups or receptacles on its inside for dripping upon the air-forcing wheel.

Fifth, the semi-cylinder or chamber placed within the carbnretingcylinder occupied by the air-forcing wheel, separating the iluid in which the latter revolves from the lrydrocarbon iuid in which the carbureting-cylinder revolves.

Sixth, the provision of hanging lamp-wick or analogous material within the air-forcing vheel when the latter revolves in hydrocarbon uid.

In the drawings, A, Fig. 1, represents acyl inder or other shaped vessel of metal, closed at each end, and made perfectly air-tight by stuffing-boxes where the spindles pass through the ends, and supported upon aframe, a c a a. One of these spindles, b', is shown having a pinion and train, c c, of wheels working in connection therewith to revolve the air-forcing wheel C, which is affixed to the spindle and revolves with it.

The air-forcing wheel C is provided with Wings radiating from a central cylinder, c, which divide the space in the air-forcing wheel into sections of the required number.

Atthe upper edge, where joined to the periphery of the wheel, the radial arms are so arranged by bending as to make one side edge in advance of its opposite. To the outer edge of the radial arms there are soldered wings, extending from the center to periphery and equal in surface to the spaces between each pair of arms, one edge only being soldered to each arm, and its opposite being an inch or more at the periphery of the wheel from the arm to which it extends, as shown at Z, Fig. 5, and in the perspective view, Fig. 4. The end of the wheel nearest the gearing is closed by a metal disk or cover from center to periphery, soldered thereto and made-air-tight.

The air-pipe d, Fig. 5, is a metal tube bent in the form therein seen, one end being soldered to the cover of the cylinder, andthe other passing through the end of the cover of the wheel C up to neanthe periphery of the wheel. In the center of the air-pipe there is .a thimble soldered for the spindle to pass through, as shown, and the cover of the wheel has an opening in the center large enough to revolve.

with duid gasoline or a heavier hydrocarbon,

or with water.

The carbureting-drum D revolvesupolfa spindle, d', which enters at one end the spin' dle revolving the air-forcing wheel, andat other passing through a stuffing-box on the outside case. The two spindles, arranged as seen in Fig. 5, passing through the stuffingboxes, render them rigid and capable'of supporting the wheel and carbureter.

The carbureting-drum D is made of perforated metal or any frame-Work, and may be covered with felt or other porous substance, or may have a reticulated or perforated surface, for the purpose of exposing a larger surface to the action of the vapor. This drum is provided witli caps or receptacles on theinner surface to raise np and drip the hydrocarbon liquid upon the wheel G, and revolves in hydrocarbon fluid, While the air-forcin g wheel revolves in separate fluid, and the two are arranged to revolve in the same or in opposite directions, and the drum, by separate gearing K Z and link-band fm, in connection with the spool I and cord and Weight which give itl motion, may have a faster or slower motionv than the air-forcin g wheel, or may be attached to the spindle b.

The regulator F is a vessel of any shape, closed at each end, havinga slot or opening, as seen in Figs. 1, 2, and 5, sufficiently wide to admit of the pipes G and H and the requisite play of the regulator from side to side,

l l when supported upon a shaft connected with one edge of said slot, the shaft passing through a stuffing-box on one end of the close vessel E, Which contains the regulator, and at the other Vresting in a box or journal within said vessel E. y

The shaft, which supports the regulator F and is the fnlcrum upon which it turns, has a small pulley-wheel, 0, 0r lever on its outer end, which, by a band, operates upon a still smaller pulley, p, attached to a spindle, to which is connected the regulator-valve R within the pipe G.

, The regulator-chamber E is lled with tluid,` l

as shown, to any height which may be found most desirable, and has an outlet-opening on thetop for the admission or escape of air.

There are suitable openings in the machine for filling or emptying each of the several parts with the iiuid required, which will be easily understood.

The operation of the apparatus may be understood by supposing the air-forcing Wheelchamber B lled with fluid .to just cover the air-tight or solid vessel o, the outer chamber, A, with hydrocarbon iluid to any height above lor below the spindle which may be desired.

The regulating-chamber is also supplied with iinid, as before explained. Weight being applied to the cord, the spool I, revolving, gives motion to the train of Wheel-work connected with the air-forcing wheel (l, which, drawing air from the action of its radial Wings and propellers through the pipe d, forces it into the chamber A, when, by passing over and through the perforations in the drum I), it is thoroughly carbnreted before passing through the pipe G into the regula-tor F, from whence it passes through the pipe H, to be used for the purposes of illumination or otherwise. The action of the regulator may be understood by supposing it illed'. By pressure of the air-forcing wheel it would be raised by turning on the fulcrum described, operating at the sameAtime on the regulator-valve R to partially or wholly close the pipe G, through which the vapor passes into the chamber F. Upon the removal of the pressure within through escape of or consumption of the gas in the pipe H, the unequal balance of the regulator would cause it to fall to the position shown in Fig.1, and the valve R would be again open fully for the admission of a further supply of vapor.

It willY be also seen that when there is no escape going von through the pipe H there can be no motion of the air-forcing wheel, it being held stationary by the pressure within the chamber A and regulator F.

The spindles b and d', Fig. 5, may be connected or revolved independently. In the former case the three stufling-boxes described will be necessary, and the train of wheels c" and c from the spool I will be sufoient; but when disconnected the spindle d will be rotated by the band m on the drums 7a l, and the middle stufiing-box may be dispensed with.

rlhe drip from the cylinder keeps the chamber B sufficiently full to operate well when once started right. The chamberB may overiow into A Without injury.

This apparatus may be used by the pressure of gas from the gas-main, instead of being revolved by mechanical appliances attached to the air-forcing Wheel; or the two may work in unison.

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

1. The air-forcing chamber C, revolving in the tank B, which is surrounded by the reservoir A, in which the carbureting-cylinder or its equivalent revolves.

2. The inverted chamber F, vibrating upon the axis and actuated by the varying pressure of the gas contained therein, to operate as ,a regulator, substantially as described.

X 3. rllhe displacing-chamber c in the chamber G, operating as described.

4. The carbureting-cylinderD, provided with cups or receptacles on its inner side, and with HUGH L. MGAVOY.
