l ATTACHEEEN'I FOR CABBURETOR-S.

Application filed April 9,

T 0 all whom it may concern.

Be it known that I, VVinLL-iir H. LENZ, a citizen of the United States, residing at Lansing, in the county of Allamakee and State of Iowa, have invented certain new and useful Improvements in Attachments for Garlniretors, of which the following is a specification.

This invention relates to an attachment for carburetors of the float type, and is designed primarily for use in connection with carburetors of Ford cars, but it is to be understood that a carburetor attachment, in accordance with this invention, can be employed for any purposes wherein it is found applicable, and the invention has for its object to provide, in a manner as hereinafter set forth, a carburetor attachment including means for overcoming the stalling of a car when traveling up grade on account of the gasoline supply being cut off due to the same being positioned at a lower level than the carburetor, and to this end the invention consists in combining with the float chamber of the carburetor an auxiliary reservoir rela tively to the float chamber that the reservoir will be supplied with gasoline to the same level as the level of the gasoline fed to the float chamber from the storage tank, and by this arrangement creating and holding what may be termed a reserve body of gasoline at the carburetor to be used at such time as, when the car is traveling up hill and the flow of gasoline from the storage tank to the carburetor is cut off by reason of the supply being at a lower level than the carburetor, this reserve or extra supply of gasoline at the carburetor will be sufiicient to enable the car to travel up grade and for adistance of one-half to a mile as by that time the gasoline within the storage tank will be at a proper level so that it can be fed to the carburetor.

Further objects of the invention are to provide a carburetor attachment for the purpose set forth, which is simple in its construction and arrangement, strong, durable, compact, thoroughly eflicient in its use; readily set up with respect to the carburetor, and comparatively inexpensive to install.

With the foregoing and other objects in View, the invention consists of the novel construction, combination and arrangement of parts, as hereinafter more specifically described and illustrated in the accompanying 1923. Serial No. 630,934.

drawings, wherein is shown an embodiment of the invention, but it is to be understood that changes, variations and modifications can be resorted to which come within the scope of the claims hereunto appended.

In the drawings wherein like reference characters denote corresponding parts throughout the several views Figure 1 is an elevation of a carburetor showing the adaptation therewith of an attachment in accordance with this invention, the attachment being shown in section.

Figure 2 is a sectional plan of the attachment. I

Referring to the drawings in detail, 1 denotes a carburetor of known construction and which is connected in a knownmanner with the gasoline tank, so that gasoline can be fed to the carburetor when occasion so requires. The carburetor 1 is of that type whereby the gasoline supplied therethrough to the intake manifold 2 'is controlled through the medium of a float 3 and which is of known construction. The type of float controlled carburetor, as indicated by the reference character 1, includes means depending therefrom to constitute a float chamber and which not only incloses the float 3 but also receives the gasoline supplied from the storage tank and as is well known, the said float type of carburetor, as indicated at 1, is formed with a i, from which depends or to which is secured the means which provides the float chamber.

In employing a carburetor attachment, in accordance with this invention, no change is made whatsoever in the construction of the carburetor, other than with respect to the means which provides the float chamber, and there is substituted for said means a chambered receptacle depending from the extension 4 and which provides the float chamber of the carburetor and an auxiliary gasoline reservoir communicating with such chamber. 1

The carburetor attachment, in accordance with this invention, comprises a receptacle consisting of an annular body portion 5 of substantial diameter, a concave bottom 6 formed integral with said body portion 5 and a downwardly inclined top 10 extending inwardly from and formed integral with the upper end of the body portion 5. Formed integral with the upper face of the bottom 6, is a vertically disposed annular partitlon depending extension till 7, of greater height than the height of the body portion 5. whereby the said partition 7 will project above said body portion. The partition 7, in connection with the bottom 6. provides a float chamber 8. The depending extension -1- extends into the partition '7 and provides the top for the float chamber 8. The partition 7 surrounds the extension 4, and is secured thereto in any suitable manner. The partition 7 is spaced a substantial distance from the body portion 5. and forms in connection with the latter and the bottom 6 an auxiliary gasoline reservoir 9. which is closed at its upper end by the top 10, and the latter is secured to the outer face of the partition 7 at a point below the top edge thereof.

The partition 7 is formed with an opening 12 for establishing communication between the float chamber 8 and the reservoir 9. The partition 7, top 10 and extension 4 are bored to provide an air vent 13, for the escape of air from the reservoir 9 when the gasoline is supplied to the latter, and the said air vent further provides for the entrance of air to the reservoir 9 when the. gasoline is being discharged therefrom.

The bottom 6 is provided with a central opening 11 for a purpose to be presently referred to. i

As is well known, a carburetor of the float type. as indicated at 1. has a depending hollow casing 17, formed with a reduced peripherally thr aded extension 18 which projects through the opening 11 and is provided with a securing nut 19. whereby the bottom 6 is coupled with the carburetor 1. The bottom 6 of the body portion has a drain valve 16 connected therewith.

The float 3 surrounds the upper portion of the extension and actuatcs an operating element 20 for the gasoline inlet needle. not shown. when the gasoline, which is indicated at 20. is supplied to the float chamber 8. it will also be fed to the auxiliary reservoir 9 through the opening, port or passage 12. and the gasoline in the reservoir 9 will be at the same level as the gasoline in the chan'iber 19. The accnn'uilation' of the gasoline in the reservoir 9 will provide for a reserve or an extra supply of gasoline which will be held at the carburetor, and such reserve or extra supply is to be used when the flow of gasoline from the storage tank to the carburetor is cutoff by reason of the supply in the tanlt being at a lower level than the carburetor. and such reserve or extra supply of gasoline held at the carburetor will be sutticient to enable the car to travel up grade from one-half to one mile asby that time the gasoline in the storage tank will be arranged at the proper level so it will feed to the carl'mretor.

Making the bottom concave in cross section facilitates a discharge of the reserve bodyof gasoline from the reservoir 9 into the float chamber 8 to enable the gasoline to be supplied to the engine The reservoir 9 may be of a capacity for the purpose desired, or in other words. so

that it will hold or store preferably about a quart of gasoline which is suflicient to drive a Ford car up grade for a distance of from one-half to one mile.

Although the preferred embodiment of a carburetor attachment in accordance with this invention. is as described and illustrated. yet it is to be understood that changes in the details of construction can be made which will tall within the light of the. invention as claimed.

hat I claim is '1. An attachment for carburetors of the float type, comprising a receptacle adapted to be connected with the carburetor body and consisting of an annular body portion, a concave bottom integral therewith and a top integral with the upper part of the body portion and extendinginwardly therefrom. a vertically disposed annular partition formed integral with said bottom and spaced from and extending above said body portion and adapted to be connected at its upper end to and closed by the carburetor body, said partition in connection with said bottom :t'orming the float chamber of the carburetor and further forming in connection with said bottom and body portion an auxiliary reservoir surrounding said chai'nber. and said partition having its lower portion provided with means for establishing comn'iunication between the reservoir and the float chamber and further integral with said top.

2. An attachment for carburetors of the float type, comprising a receptacle adapted to be connected with the carburetor body and consisting of an annular body portion, a con ave bottom integral therewith and a top integral with the upper part of the body portion and extending inwardly therefrom. a vertically disposed annular partition formed integral with said bottom and spaced from and extending above said body portion and adapted to be connected at its upper end to and closed by the carburetor body. said partition in connection with said bot tom forming the float chamber of the carburetor and further forming in connection with said bottom and body portion an auxiliary reservoir surrounding said chamber. said partition having its lower portion provided with means for establishing communication between the reservoir and the float chamber. and said partition and top having registering means to constitute a vent opening for said reservoir. and said partition integral with said top.

In testimony whereof. T attix my signature hereto. I
