Specification 'ef Letters Patent.

Patented July 10, 1906.

Application filed September 11, 1905. Seri'aL No. 278,053.

To all whom,v it mar concern:

Be it known that I, THOMAS MoOoaMIoK, a citizen of the United States, residing at Mount Pleasant, in'the county of VlZestmorecapable of holding a comparatively great quantity of fuel and maintaining it in harmless condition, vaporizing meohanism'being also provided, which automatically returns all surplus or unvaporized fuel takenfrom the reservoir back to the same.

The referred embodiment of the invention is illustrated in the accompanying draw inns, wherein- V igure 1 is a vertical longitudinal sectional view through the carburetor. Fig. 2- is a horizontal sectional viewtherethrough, and Fig. 3 is a vertical cross-sectional view.

Similar reference-numerals designate corresponding parts in all the figures of the drawmgs. a In the embodiment illustrated an oblong casing 4 is employed, preferably, though not necessarily, constructed of sheet metal and forms a mixing-chamber 15, the bottom ofsaid chamber being perforated, as shown at i 16, and bein spaced from the partition 5 ,:the portion of the partition beneath the perfo rated bottom 16 also being perforated, as

shown at 17 A plurality of air conduits or pipes are provided with upright inlet termi-r.

nals 18, that 1pass through the partition 5 and telescope Wit nipples 19, carried by the bot- A fillingw tom ofth'e boxing The pipes are thus in communication with-the lair-compartment 9; Themain portions 20 of the pipes or conduits extend in a substantia-lly horizontal directionwithin thereservoir and areperforated, as shown at 21:.- The said reservoir is com pletely-filled with suitable absorbent packing ;material, such as waste or asbestos, (shown at 22,). the material completely surrounding theperforated-portions of the pipes. S'aid pipes also terminate in upstanding discharge ends 23', that project above the partition 5, and include discharge-nozzle elbows 24:, that project into the mixing-chamber 15, being thus located above the perforated partition .5; I A suotion-pipe25 is connected to the casingland has its Inlet end in communication with the separating ohamber 6'. This suc tion-pipe is adapted to be connected to an explosive-engineor other device for creating a current of air through the pipes. To=supply the carburetor-with fuel, it is only necessary to remove-the plug 13 and pour fuel into the air-compartment 9, whereupon said fuel will flow into the air conduits or pipes and, escaping through the erforations thereof, will be I thoroughly absor ed by the packing.

In oeration a current of air is created throu the mechanism by the means attache to the suction-pipe 25. This will cause a partial vacuum within the casing, which will be relieved by'the opening of the check-valve 1 1. The air thus passing through the compartment 9 will enter and traverse the air conduits or pipes, taking up and vaporizing the fluid therein and finally escaping into t e mixing-chamber 15. From thence it'will pass through the perforated bottom into the separating-chamber 6 and to the suc- .tion-pipe 25. If an abnormal amount of fuel is collected in the pipes, 'the surplus or unvaporized portion will be drawn therefrom and delivered into the mixing-chamber, from rated bottom onto the perforated partition 5, constituting a top fo'rthe reservoir. Through this top or partition it will find its way back into the reservoir, where. it will be absorbed by the packing.

It: will be apparent that this structure is an exceedingly-simple one, and experience has demonstrated that it will properly and thorv whence -.,it will gravitate through the perfo- ,oughly vaporizefuel in the reservoir. While 1 a said reservoir will contain a considerable quantity of fuel, it will be evident that the same will be maintained in a comparatively harmless condition, as it is absorbed by the packing. Furthermore, any portion of the fuel that collects in the pipes will be immediately withdrawn therefrom when the engine is operated and returned to the packing, so that no body of fluid of any great amount will collect in the apparatus.

From the foregoing it is thought that the construction, operation, and many advantages of the herein-described invention will be apparent to those skilled in the art without further description, and it will be understood that various changes in the size, shape, proportion, and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

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

1. In a carbureter, the combination with a casing, of a perforated partition located there- 1n, said partition subdividing the interior of the casing into a lower reservoir and an upper separating-chamber, an air-pipe having a perforated portion extending through the reservoir, said pipe extending into the separating-chamber and terminating therein above the partition, and a delivery-pipe communicating with the separating-chamber.

2. In a carbureter, the combination witha casing, of a (perforated partition located therein and sub ividin'g the casing into a lower reservoir, and an upper separating-chamber, an air-pipe having a substantially horizontal perforated portion extending through the reservoir above the bottom thereof, said pipe having an upturned end portion that extends through the partition and terminates over the same in the sep arating-chamber, and a delivery-pipe communicating with the separating-chamber.

3. In a carbureter, the combination with a casing, of aperforated partition located therein and subdividing the same into a lower reservoir, and an upper separating chamber, an air-pipe having a downwardlyextending inlet from the top of the casing, asubstantially horizontal perforated portion extending through the reservoir, and an upturned end portion that extends through the partition and terminates over the same in the separating chamber, said upturned end portion above the partition being imperforate, and a delivery-pipe communicating with the separating-chamber.

4. In a carbureter, the combination with a casing, of a partition located therein and subdividing the same into a lower reservoir and an upper separating-chamber, an air-pipe having a perforate portion extending through the reservoir, said pipe extending into the separating-chamber, a mixing-chamber located in the separating-chamber and having 5. In a carbureter, a reservoir for fuel having a perforated top, an absorbent packing in the reservoir below the top, an air-conduit extending through the reservoir, through the top and terminating over said top, said conduit having a portion located in the reservoir, surrounded by the packing and perforated, and means communicating with the space between the top and terminal of the conduit to cause a downward draft from the latter and to effect a downward discharge of unvaporized fuel onto the top. 6. In a carbureter, the combination with a reservoir having an open top, of a mixingchamber located above the reservoirand having an open bottom, a perforated air-conduit extending through the reservoir and discharging into the mixing-chamber, and a suction-pipe having communication with the space between the open top and bottom of the reservoir and chamber to cause a downdraft through the open bottom of the mixingchamber.

7. In a carbureter, the combination with a reservoir having a perforated top, of a mixing-chamber located above the same and having a perforated bottom disposed over and in spaced relation to the top of the reser voir, and an air-conduit having a perforated portionextending through the reservoir, said conduit extending across the mixing-chamber and having an outlet communicating with said mixing-chamber.

8. In a carbureter, the combination with a casing, of a substantially horizontal perforated partition located therein and dividing the interior of said partition into a lower reservoir and an upper separating-chamber, an air-conduit having a downwardly-extending inlet portion passing through the partition, an offset perforate portion located in the reservoir, and an outstanding discharge that extends through the partition and terminates above the same, and a suction-pipe connected to the separating-chamber.
