"UNITED STATES PATENT oFFi c-s.

, ROBERT E. BALLOW, or ESTANCIA, NEW MEXICO.

1 '0 all whom it may concern Be it know-11 that I, Ronnnr E. BALLQW, a :itizen of the United States, residing at Estancia, in the county of Terrence and State of New Mexico, have invented certain new and useful Improvements in Carburetors, of whichthe following is a specification- This invention relates generally to the art of fuel atomizers for internal combustion engines, and "has more particular reference to what is known in the art as a carburetor,

the primary object of the invention residing in the provision of. such a device wherein the gasoline or other fuel is completely atomized before the same passes to the intake manifold of the engine, thereby resulting in the economical and efficient operation of the engine. 7

An additional object of my invention is to provide a' carburetor, wherein the fuel is subjected to a whirling action under the influence ofthe engine suction for producing said complete atomization ofthe fuel.

A still further and important object of the invention is to provide a carburetor wherein a relatively great amount of air is taken into the manifold together with a relatively small amount of fuel, but due to the fact that complete mixture of these elements is accomplished, a satisfactory combustible mixture is produced.

Another object is to provide means for absolutely drawing the fuel from the float chamber of the carburetor and subjecting the same to a whirling action. before the fuel passes to the engine cylinders.

Another object resides in the provision of means for automatically subjecting the fuel to a whirling action, and this due to the suction' created in the engine cylinders.

A final and salient object is to provide a carburetor that is relatively simple of construct-ionand efficientin operation and one that may be entirely disassembled by unskilled persons for repair or renewal purposes.

With the foregoing and other objects in view as the nature of the invention will be better understood, the same comprises the novel form, combination and arrangement parts hereinafter-more fully described s chimera h tViljli the accompanying drawings oamaunn'ron, I "1 Application filed May 10, 1924. Serial No. 712,305.

' ln the drawings wherein like reference characters ind cate corresponding parts throughout the different views:

Figure 1 is a detailed vertical sectional view of a carburetor constructed in accord ance with the present invention. Figures 2 and 3 are detailed transverse sectional views takensubstantially upon the lines 22 and 33 of Figure 1 and looking in a downward direction. it

Figure 4: is aside 'elevat-ional view of the 1 fuel whirling or operating device per so, that constitutes a mayor element of the present carburetor construction, and

Figure 5 is an enlarged perspective view of a member that is associated with the lower end of said fuel whirling or operating device, the use of which results in the effective feeding of the fuel into said whirling or opcrating device.

Now, having particular reference to the drawings, my novel carburetor among other elements constitutes the provision of a fuel bowl 5, that is open at its upper end, and formed at itsbottom wall with a collared opening 6. This bowl 5 is further formed at one side of said collared opening with a threaded opening 7, within which is thread ed a' nipple S, the inner end of which is formed with an extension 9, to the upper end of which is suitably pivoteda ring shaped float lOfT'his member 8 is maintained within said threaded openings through the medium of a jam nutll and setscrew 12, the lower end of said nipple being formed with an internally screw threaded socket for the threaded reception of one arm of an elbow fitting '13, the other end of which is adapted tobe attached to the gasoline feed line. i

Extending throughsaid nipple 8 is a relatively restricted fuel, passage-way lt, the, upper end of which is bevelled to provide a valve seat, with which cooperates a needle valve 15, that is actuated to opened and closed. positions through the falling and rising of saidringfloat 10. c

Disposed within the central collared opening 6 of the fuel bowl 5 is ae pendent hollow nipple 16, that is formed upon the lower end of a circular shaped cylinder 17. The nipple 16 of this cylinder 17 is exteriorly screw threa'l'ed whereby the same may be inanieithin the bottom wall ipening; of the fuel bowl 5, through the medium of a jam nut 18. The fuel within the bowl enters said cylinder 17 through the medium of a series of passage-ways 19 formed in the lower end thereof, and for the purpose of allowing said cylinder to be drained whenever necessary, there is threaded within said nipple a plug 20, the inner end of which is pointed for positioning upon a valve seat 21 at the inner end of said nipple, said nipple communicating with the cylinder through the medium of a passage-way 22. This plug is formed with a bore 23 that extends inwardly to a point adjacent the pointed end of the plug, theinner end of said bore having communication with the interior of the nipple through the medium of a right-angularly extending passage-way 2 1, it being obvious that a slight unscrewing of this plug will allow the fuel within the cylinder to pass into the nipple through the passage 22, and thence inwardly through the passage 24, and then through the bore 23 of said nipple 20.

The upper end of the cylinder 17 is internally screw threaded for receiving the lower externally screw threaded end of a pipe 25, that is formed centrally of and depends from the fuel bowl lid 26. Formed upon the external surface of said lid 26 and at its marginal edge is an upstanding circular collar 27 that is externally screw threaded at its upper end, whereby a similar shaped collar 28 may be .secured thereto, through the medium of a cushioning sleeve or collar 29. This collar 28 is an integral part of a T- iitting 80, that includes a rectangular pipe 31 that has communication with said collar 28 through the medium of a circular restricted passageway 32.

Previous to the threading of the lid carrying pipe into the cylinder 17 there is threaded within the lower end of said pipe a sleeve 32, the lower end of which is formed internally with a bearing raise-way The upper end of the lid carrying pipe 25 communicates with the interior of the lid. carrying collar 27 through an opening in the lid, and inwardly of the upper end of this pipe, the same is internally threaded for the reception of a threaded sleeve 34, that is also formed at its upper end with an internal ball bearing raise-way 35.

Fxtending downwardly through said pipe 25 and disposed centrally therein is a hollow relatively elongated stem 36 of a hollow fuel whirling member 87 with the interior of which said hollow stem 36 con'nnunicates. At the upper end of this stem 36, the sameis threaded for the threaded. reception of a bearing collar 38 between which and the last mentioned raise-way are suitable bearings 39. The lower end of the stem 36 is threaded for the reception of a sheet metal sleeve 40, spaced from the inner end of which is formed a raise-way, between which and the raise-way 33 are ball bearings ll, that cooperate with the'other bearings 39 for allowing a free rotation of the stem within the cylinder 17 and pipe 25.

The lower end of the sheet metal sleeve 10 is formed upon diametrically opposite points with inwardly extending dished blades 42, the angle of which is such as to scoop up the fuel within the cylinders 17 during the rotation of the stem 36 for thereby insuring the positive entrance of the fuel into said stem.

The hollow fuel whirling member 87 is formed with radial dished blades or fins 3, as well as radially extending diametrically disposed hollow chambers a l that communicate with the interior of said hollow member 37. These chambers 1 1 are formed upon their top sides with threaded openings, within which are threaded relatively small fuel outlets 1-5.

The lid carrying collar 27 is formed at a point beneath the whirling member 37 with air inlet openings 46, and it will be obvious that when the carburetor is installed, the suction of the engine cylinders will result in the intake of air through the openings -16, which air impinging upon the blades 43 will cause the ratchet rotation of the whirling device for drawing the fuel upwardly through the stenr36, and the same will discharge from the outlets 1 5 in an operating or whirling action, which will permit of a thorough mixture of the air and fuel in the collar 28 of the T-shaped fitting.

One end of the horizontal pipe portion 31 of the fitting 30 is formed with the usual manifold attachment flange 47, and within this end of said horizontal pipe 31 is the usual throttle valve 18 operable through the medium of an actuating arm 49 by the usual accelerator mechanism employed. The opposite end of said horizontal pipe 31 is equipped with an air control valve 50 operable in any manner desirable.

lVithin the restricted passageway 32 between the collar 28 and horizontal pipe 31 is a valve 51, operable through the medium of a stem 52 whereby the amount of mixture passing from the carburetor may he manually controlled independently of the throttle valve -18.

The hollow member 37 of the fuel whirling device may be and preferably is formed with a threaded opening for the reception of a plug 53 whereby the same may be cleaned whenever necessary.

It will thus be seen that I have provided a highly novel, el'licient and durable form of carburetor, and one the use of which will result in economical and efficient use of fuels, and wherein the cheaper grades of gasoline or even kerosene may be employed due to the fact that the fuel is entirely atom ized before passing to the engine cylinders.

Minor changes may be made in the invention without departing from the spirit and scope of the appended claim.

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

In a carburetor, a fuel bowl, a pipe depending from the top of the fuel bowl and terminating a distance from the bottom thereof, a cylinder risingfrom the bottom of the bowl and communicating with the pipe, said cylinder merging at its bottom end into a nipple which extends through an opening provided in the bottom of the bowl, drain means at the bottom end of the nipple, said cylinder provided with openings adjacent the bottom of the fuel bowl for re ceiving fuel therefrom, a hollow stem rotat ably mounted within the pipe and the cylinde'r and having one end terminating within said cylinder and the other end terminating above the fuel bowl, bearings for the stem in both the pipe and cylinder, means on the end of the stem within the cylinder for forcing gasoline from the cylinder upwardly through thehollow stem, a mixing chamber above the fuel bowl and provided with air inlet openings, the upper end of said hollow stem terminating within the mixing chamber above the openings thereof, a head on the upper end of the hollow stem,

1 fuel out-lets projecting upwardly from the head, and fins radiating from the head so that air being thrust through the openings of the mixing chamber will impinge against said line for causing the rotation of the stem.

In testimony whereof I aliix my signature ROBERT E. BALLOW.
