TO ALL WHOM IT MAY CONCERN:

Be it known that we, ELIAS S. H-UTCHINSON, 'and HUGH L. Mc-AVOY, of the cit'y 'and county of Baltimore, and State of Maryland, have invented and made new and useful Improvementslin Apparatus for Carburetting Air to be used for illuminating and heating purposes; and we` do hereby declare the following to be a full, clear, and exact description of the. nature, construction, and operation of the same, suilcient to enable one skilled in the art to which it is allied lto construct and use the same, reference being had to the accompanying drawings, in which our improvements are shown as applied to the apparatus for carburetting air, patented by HUGH- L. McAVOY, and assigned to himself and ELIAS S. HUTCIIINSON, and dated on the 19th day of Septem ber, 1865. 4The drawings represent the following:

Figure 1 is a longitudinal section of a hood, C; also showing, by the broken line y z, un external view of the air-forcing wheel A, tig. 2. f

Figure 2 is a longitudinal section of the air-forcing wheel A, outer drum B, and hood C, air pipes d and e, and connection fto air pipe g.

Figure 3, top view ofhood C. A

Figure 4 is a transverse section of air-forcing wheel A, outer drum B, and head C, on the line p g, g. 3, sh owing receptacles on the internal and external peripheries of A and B.

The invention consists in surrounding any air-forcing wheel of apparatus for carburetting air (by the use of any hydrocarbonaceous fluid suitable for the purpose) with drums or hoods, the external and internal periphd cries-of which being either corrugated, roughened, or supplied with receptacles whereby a minute portion of the fluid is taken up hy the revolution of the air-forcing wheel' and drum or drums within the reservoir or receptacle containing it and them, and their surfaces, external and internal, are continually kept wet or moistto facilitate .the carburetting process on the air forced through theapertures formed lbythe disposition of the drum or drums and hood to be described.

In the drawings letters refer to similar parts in all the figures- A, representing in iig. 1 part of the external periphery of an air-,forcing vheel, and 4part of a drum, B, bothrrevolving on the same spindle and in the same direction. The method of connecting' the airforcing wheel and drum is by studs placed at intervals, fixing the outer drum at such a distance from the air-forcing wheel as to just clear strips of metal soldered on one edge nearly the whole length, and on to the external periphery of the former and internal periphery of the latter, which strips are set or turned outwards on the other edge so as to form small receptacles, for the purpose before explained. Only one extremity vof the drum B (which is-supplied with strips on its external periphery, as before described 'for the interioxg) has a side with an opening a little larger than vthe diameter of the spindle, to permit the hydrocarbonaceous Huid to come to a' level in its reservoir, the other end being left open, as shown in g. 2, thus forming a vent above the fluid level for the air in its passage through the pipes d, Snc., the interior of air-forcing wheel, andthence by the passage between the inner and outer surface of drum and'hood to a reservoir or holder,` for service for Vthe purposes explained. The interior of the air-forcing wheel A has strips also, :is described b'efore, soldered on its interior periphery betweep the radial arms, as shown more clearly in g. 4, which also shows bysection the position of external drum and hood; the latter being bent in the form of a semicirole in the centre, covering half the circumference of the outer drum horizontally, and half the diameter of the end nearest the train of wbeclhwork, which gives by weights, 32e., motion to the air-forcing wheel and drum. The remaining parts of the hood are turned upwards to permit of being fastened between' the joints of the upper and lower sect-ion of the patented machine or apparatus alluded to. A train of wheel-work and dials may be suitably attached Vto the machine, so as to` indicate, in connection with the knowrr'eapacity of the openings through which the air passes, a measure of the quantity of air passing through the carburetter.,

,.The operation of the-air-forcing wheel and drum and hood may be now explained. By their revolution in Vthe hydroearbona-ceous fluid in the vessel which contains it and them, small portions of th'e fluid are taken up by the receptacles formed'by the strips, as before described, carburetting the air forced between the interior and exterior of the air-foreing wheel and drum and hood on its Apassage to the pipes where it is to be employed for the purpose of illumination or heating, the operation fitting it for either of these purposes.

o cinzia 2 Having described our invention, what we claim therein as new, and desire to secure by Letters Patent, is- 1. A revolving drum partially submerged in hydrocarbon fluid, and provided on its interior or exterior periphery, or both, with buckets, receptacles,reticulations, or depressions, which raise portions of the Huid for the purpose of moisteningthe surface which is exposed to the air in the earburetter.

2. We claim the combination of the inner and outer drums, revolving together, and between whose moistened surfaces the air is conducted, substantially as described. A

3. In combination with a revolving drum provided with devices for raising the uid, we claim the hood C, which compelsthe air to traverse the outer periphery of the drum, as described and represented.

4r. In combination with the air-forcingA maehinenve olaimthe two concentric series of fluid-raising devices and the hood, arranged substantially as described and represented.

HUGH L. McAVOY.
