MOISTURE-SUPPLYING ATTACHMENT FOR CARJBURET(JRS.`

Application led February 23, 1924.

This invention relates to moisture supplying attachments yfor carburetors of internal combustion engines.

An object of the invention is to provide an attachment for carburetors of internal combustion engines, which is adapted to supply moisture to the air in the intake manifold which is broken up into finely divided form or vapor and interinixed with the vaporizcd fuel in the carburetor or supplied to the internal combustion engine.

Another object of the invention resides in providing a fitting adapted for removable attachment in the air intake of a carburetor having a water container connected therewith, and provided with air intake openings sothat the suction of the engine will draw air through the water container and the fitting into the carburetor and in drawing this air therethrough will operate to take up moisture from the tank which is evaporated and broken up into finely divided form and intermingled with the vaporized fuel as it passes through the carburetor.

The invention includes other objects and improvements in the details of construction and arrangement of the parts for attachment to a carburetor which is more particu larly pointed out in the following description and claim directed to a preferred form of the invention, it being understood however, that variations in this construction may be made without departing from the spirit and scope of the appended claim.

Tn the drawing, forming a part of this application rllhe figure illustrates a vertical sectional view through the water container and a por-- tion of the fitting for the carburetor.

1 indicates a tubular fitting of angular form, provided with a flanged portion 2 adjacent one end thereof, which end is adapted to be inserted in the air intake of the carburetor of the internal combustion engine.

The other end of the fitting is extended upwardly as shown in the drawing and receives the lower end portion of a tank or casing 3 of cylindrical form, and which is mounted concentrically on the upwardly eX- tending end of the fitting 1, the tank being provided with an opening t in the lower end thereof to receive the fitting, and a horizontal perforated partition wall 5 having a Serial No. 694,794.

central opening into which the upper end of the fitting is secured, the perforated partition wall and the bottom wall of the casing` or tank securing said tank on the litting.

An overflow pipe is indicated at 6, and has its lower end formed with a return bend T, which extends through the bottom wall of the tank 3. the upper end of the overflow pipe terminating below the horizontal plane of the perforated partition wall 5 and 65 being designed for determining the water level within the tank, which must be maintained below the partition wall 5, so that in filling the tank, it can be readily ascertained when the proper level of water is reached in the tank by examining the overflow pipe. The upper end of the tank is closed by the top wall 8, which is provided with a hanger extension 9 adapted toibe attached to a suitable portion of the engine to properly support the tank in au upright position as shown in the drawing, the top wall 8 also forming a support for the filler tube 10, which extends downwardly through the tank and the partition wall 5, and is provided with a funnel like mouth 11 at the upper end, in order that the water may be poured into the filler tube for 'Killing the tank. A valve 12 is provided at t-he upper end of the filler tube for closing the passage therethrough.

The upper end portion of the tank 3 .is provided with a plurality of air inlet openings 13 arranged in spaced relation around the entire upper end of the tank, and a water conducting` tube 111 is mounted in the partition walls 5 and has one end extended downwardly in the casing to a point adjacent the bottom thereof, while the other end is formed with a return bend 15, the end portion of which extends downwardly in the upper end of the tubular fitting 1.

lhen the fitting lis properly attached to the air intake of a carburetor, and the engine thereof is operating, the suction in the intake manifold serves to draw air through the openings 13 and downwardly into the tubular fitting 1, which suction will act through the water conveying pipe 14 for sucking water therethrough to be 105 dropped into the tubular fitting 1, the water being broken up into finely divided form and vaporized by the air as it leaves the end of the water supply pipe 14, so that it will ntermingle with the vaporized gas when it reaches the eznflnu'etor 'for :L Subsequent conveyance through the intake manifold into the engine.

It, will be clear from the above description, therefore, that a convenient and novel attachment hns been provided for carburetors, adapted to cont-tin moisture for supply to the engine, which may be manufactured :it n relatively small cost by reason ot its simplicity of structure.

lli/That claimed is:

il, moisture Supplying nttnehnlent for enrburetors ot internal Combustion engines including nn elbow fitting haring one end normally positioned in :in upright position :1nd the other enfl :nlnptetl 'for uttzielnnent to the intuke oi :i Carburetor` n cylindrical tank mounted on the upwardly projecting),v enfl of seid litting' and having the end terminating in the central portion of the tank,

u partition well provided with n, plurality of perforetions mounted in the tank and on the fitting below the upper end thereof, the upper end of said tzrnk being formed with :i plurality of air inlet openings, an overflow for the tank tor maintaining the Wnter level below the perforated partition, filler ineens for the tank, and a Water Clelivery pipe mounted in the partition Wall :and extending' in close proximity With the bottom of the tank having the other end `lorn'ietl with n. returned end extending into .esiiil lifting', whereby air being sucked tlirougzh the trink intl the fitting will drew :i i'n'etletermined :miount of' Water through Suirl water delivery pipe into the fitting.

ln testimony whereof I nl'ix my signuture.
