VAPORIZER Filed Sept. 8, 1928 2 Sheets-Sheet 2 Qvweutoz' yilda 62015006 w h Bum m (a W Patented July 8, 1930 UNITED STATES PATENT OFFICE VAPORIZER Application filed September The present invention relates to devices for generating a combustible mixture for burning in stoves and the like. In localitles where a supply of gas is not available, oil

stoves are frequently used as a substitute for the well known gas stove. A certain amount of inconvenience is always involved in using oil stoves and this invention embodies a device which can be used with an ordinary gas stove, thus eliminating the objectionable odors, uncleanliness, and difficulty of operation of oil stoves. 7

It is proposed to provide a device which may be used with a large supply tank, thus avoidingthe necessity of refueling at frequent intervals. By constructing the parts as .a device independent of the stove, it may be placed at a remote point and the combustible vapor carried to the stove through a pipe line. 7

Accordingly, an object of the invention is to provide a generating device which may be placed at a remote point and used to supply a combustible mixture as needed. A further object is to provide a constructionwhich will not emit offensive odors nor accumulate dirt, but will operate efficiently and quietly.

A still further object is to provide a construction which is compact and easy to assemble as well as being simple in operation. Further advantages will appear as the invention is described more fully in connection with the accompanying drawings, wherein:

Figure 1 is a view in elevation, partly broken away and in section, showing a preferred form of the invention.

Figure 2 is a view in section, taken on line 22 of Figure 1, and looking in the direction of the arrows.

I Figure 3 is a view in section, taken on line 3-3 of Figure 1, and looking in the direction of the arrows. Figure 4 is a viewin section, taken on line H of Figure 1, and looking in the direction of the arrows. i

Referring to the above drawings, a designates a supply tank for a quantity of gasoline or other suitable fluid a which may be introduced through an inlet (1 The top of the container is provided with an aperture 8, 1928. Serial No. 304,801.

a and a flanged portion (1 upon which a threaded neck a is secured.

A fixture b is threaded at its lower extremity to engage the neck and is thus secured upon the tank. The fixture is formed as a block, or unitary casting, a bracket 7) being provided upon which an electric motor b is supported. The fixture is formed with a machined face 6 over which a cover plate 6 is secured. The cover plate is apertured to provide a port 7) through which air may be drawn for producing the mixture.

Within the fixture and cover plate, a chamber b is formed for receiving a fan 6 The motor drives a shaft 6 upon which the fan is secured, thus providing a means for rotating the fan. An exhaust port 72 communicates with a duct 6 which conducts the air from the fan to a chamber 6 formed in the fixture, as indicated by the arrows in Figures 1, 2 and 3.

The chamber 72 is provided with an extension comprising a cylindrical member 0 .and a head 0. The cylindrical member is confined between the fixture and head by means of bolts 0 An outlet 0 is formed in the head, through which the combustible mixture passes to the pipe line of a stove.

The fixture is provided with a tube d which extends into the tank and carries a housing elf near the bottom thereof. This housing contains a centrifugal pump d which takes the fuel through an aperture (i and forces it through a pipe d. A power shaft 03 is carriedin the tube d, the shaft being driven through a worm wheel 03 and a worm d mounted on the shaft b".

Pipe d extends through an over-sized duct 6 in the fixture and the fluid is discharged at the top of the chamber, as indicated at (i Within the chamber, a porous substance 6 is provided, the fluid which is discharged at the top of the chamber, percolating down through the substance. The percolating fluid is met by the upward fiow of air provided by the fan 6 and the resulting combustible mixture in gaseous form is carried off through the outlet 0. Y

Itwill be apparent that the fixture is of such nature that it can be easily manufactured at low cost. The number of moving parts and bearingsois reduced to a minimum and the device requires very little attention.
