IMPROVED APPARATUS FOR CARBURETING AIR..

Specilication forming part of Letters Patent No. 45,456. dated December 13, 1864.

Figure l is a transverse section of an apparatus embodying my invention, and Fig. 2 is a longitudinal section ofthe same in the line was.

Similar letters of refererce indicate corre-- sp )nding parts in the two iigures.

The object of this invention is to obtain a more effectual method of mixing together air and hydrocarbon liquid for the purpose of producing inilamm able gas to be used for illuminating or heating; and to this end theinvention consists in forcing air ard oil through a rotating wheel having winding passages, in which the oil and air are conducted to the center ofthe wheel from a surrounding oil-vessel and kept in a constant state of agitation and mutual compressure until discharged through central perforations in one end of the wheel into a receiver, from which the gas which has been compounded of the oil and air may be conducted oft' to be burned, while the oil which has not been mixed with the air is returned to the vessel or reservoir, all as will be hereinafter fully described.

Thel following description will enable others skilled in the art to which my invention appertains to fully understand and use the same.

In the accompanying drawings, A represents a cylindrical vessel or reservoir, in which is mounted a wheel, B, having a series of winding passages, B B B', each of which terminates at the center ofthe wheel and communicates with the interior of the vessel A, as clearly represented in Fig. l. A central hollow shalt, U, carrying a pulley, C', may be connected with any suitable mechanism, such as that of a clock, for producing the rotation ot' the wheel B. One of the journals upon which said wheel rotates is constituted by the shaft G, and its other journal consists of a hollow neck or tube, D, which has a sleeve-like bearing, D', the latter being somewhat larger than the tube D, in order that a space may exist between the journal and its bearing for the purpose to be explained. The tube or journal D communicates at the center ofthe wheel B with the spaces B through perforations d. The tube D and hollow shaft C lead into the gas receiver or chamber E, from which the gas is conducted olf for use through a pipe, E. F is a pipe communicating at its respective ends with the vessel A and chamber E, and employed in addition to other provisions to return the oil from the chamber to the vessel.

H is avalve adapted to open automatically, when the. apparatus is in operation, to admit air to the interior ofthe vessel A, and to be closed by a spring, h, when the operation ceases, for the purpose of excluding air, and thus preventing the evaporation of the oil or hydrocarbonaceous Huid.

G is a pipe, through which the vessel A may be supplied with the hydrocarbon liuid or oil. The hollow shaft C, near the end, at which it forms a journal-form for the wheel B, communicates with the interior ofthe vessel A through perforations c.

Operation The hydrocarbon fluid or oil, on being introduced into the vessel A, finds its level in the passages B of the wheel B, and when the oil has risen to about the horizontal center of the wheel B the supply should be shut off, so as to permit the upper part of said wheel to be occupied by air, which enters the vessel A through the valve H in the manner described. As the wheel rotates and the entrances of the air-containing passages ofthe wheel B are presented downward, the oil which is taken in holds the air within the passages B and forces it to the center ot' the wheel B, together with the oil which the wheel first contained. The continuous pressure toward the center of the wheel forces the oil and wa ter through the tube D and into the chamber E. In going through the passages B the air is held between and in contact with two'coluinns or bodies of oil, and the motion ofthe wheel B agitates the oil and airin such a way that they become intimately mixed and become a gas eous compound before passing into the chainber E. Any oil which may enter the'chainber E and the condensed vapor or gas therein ilows back into the vessel A through the space between the tube D and its bearing D', and should the oil become excessive in said chamber E, it tlows with increased rapidity into the vessel A through the pcrforations ein the hollow-shaft C and through the pipe E.

The partial vacuum formed-within the vessel A by the action of thc wheel B permits the pressure from the external atmosphere to open the valve H, and the air then passes in to be carbureted in the manner described.

As no water is used in this process of generatin g gas, the contents of the apparatus cannot freeze.

Having thus described my invention, the following is what I claim as new and desire to secure by Letters Patent:

l. Carbureting air by means of a revolving volute Wheel B B', operating Within a vessel or reservoir, A, substantially as described.

2. The use of the journal D, made smaller than its bearingD, to permit the oil to be returned from the gas-chamber E to the vessel A, as herein set forth.

3. The employment, in connection with the vessel A and wheel B, of a valve, H, adapted to automatically open when the apparatus is in operation for the pupose of supplying air to be carbureted and to close when the operation is suspended in order to prevent the oil from evaporating, as explained.

4. The hollow shaft C, having perfor-ations c, and communicating with the gas-chamber E and vessel A, so as to constitute a medi-um for returning the oil from the chamber E to the vessel A. g

5. As means for returning the oilA from the chamber E to vessel A, and to be especially available when such oil is in excess, the pipe F, arranged and. employed in the manner described.

'lhe above specification of my improved mode of carbureting air signed this 14th day of November, 1864.
