FUEL MIXER.

Application filed May 16,

This invention relates to automobile accessories and morG'particularly to afuel mixer adapted to be mounted adjacent the junction of a carburetor and intake manifold so that a charge passing from the carburetor through the manifold will be acted upon by the mixer and free gasoline in the charge broken up.

One object of the invention is to provide amixer including a wheel'adapted to be rotated by the charge passing through the manifold and having blades which will very effectively break up free gasoline in the charge and cause it to be thoroughly vaporized.

Another object of theinvention is to provide an improved type of mounting for the wheel and so form the mounting that air may pass inwardly between bearing arms between which the wheel rotates and thereby become thoroughly mixed with the charge of combustible fluid passing from the carbureter through the manifold.

Another object of the invention isto provide. a deviceof this character which may be easily installed and firmly held in proper position when in use.

The invention is illustrated in the accompanying drawing, wherein igure 1 is a view showing a carburetor and a portion of a manifold partially in sec tion with the improved mixer applied thereto;

Fig. 2 is a sectional view taken on. the line 22 of 1;

F is a perspective view of a gaket forming a carrier for a modified form of mixer;

F 4 is a transver e sectional view through the gasket with the modified form of mixer applied thereto;

Fig. 5 is a sectional view taken on the line 5-5 of Fig. 3, and V Fig. 6 is a perspective View of a mounting orming a portion of the mixer shown in ig. l. 7

The vaporizer shown in Figs. 1 and 2 is intended to be mounted in the manifold 1 V adjacent the end thereof which is connected with the carburetor 2 and in order to mount the vaporizer an opening 3 is drilled or otherwise formed in the manifold, as shown in Fig. 1. The mounting at which forms a portion of the vaporizer is provid d with bearing arms 5 which extend from a base 1927. Serial N0. 190,297.

6 and rotatably support a mixing wheel 7, the blades 8 of which'are formed with longitudinally extending slots 8'. This wheel is disposed transversely in the manifold and is rapidly rotated by the charge sucked from the carburetor through the manifold. A portion of the charge passes through the slots in the blades and, therefore, free gasoline contained in the charge will be acted upon and very thoroughly broken up. An opening is formed in the base 6 of the mounting and carries a threaded tubular stem 9 which projects into the opening 3 formed in the wall of the manifold and engages in the threaded end portion of the bore 10 formed axially through the fastener or carrier 11. By referring to Fig.1, it will be seen that the inner end portion of the carrier is re duced to form a neck 12 which fits snugly in the opening 3 and is of a depth corresponding to the thickness of the manifold wall. Therefore, the fastener 1 ay be tightened to firmly retain the mounting in place with the wheel extending transversely in the manifold. A hollow valve seat. 13 is screwed into a threaded outer end portion of the bore 10 and forms a seat for a valve ball lat which is yieldably held upon the seat by a spring 15 confined between the valve ball and end of the stem 9. By this arrangement the bore will be normally closed by the valve ball but when a suction takes place through the manifold from the carburetor to a cylinder of an engine the valve ball will be drawn away from the seat and air may be sucked into the manifold. This air passes inwardly between the arms 5 of the mounting and since the blades of the mixing wheel pass across the inner end of the tubular stem the charge of air will be acted upon by the blades of the rotating wheel and mixed with the charge passing from the carbureter. Therefore, a very explosive charge will be fed to the engine. By adjusting the valve seat the tension of the spring may be controlled and the quantity of air which passes inwardly with each suction regulated.

In Figs. 3, 4;, 5 and (3, there has been shown a modified form of vaporizer which includes a gasket 16 adapted to be secured between the carbureter and intake manifold and having a passage 17 which registers with the bore of the manifold and outlet of the carburetor. An opening 18 is formed through the gasket, as shown in Fig. 5, and the side faces of the gasket are formed'with grooves constituting seats-19 adapted toireceive the base portions 20 of'arms 21 corresponding to the arms 5. Screws 22 may be employed t retain the arms in place or a small bolt substituted therefor if so desired. The bearing arms 21 extend radially of the opening or passage 17 and rotatably mount a mixing wheel 23 which corresponds, to the' wheel 7 and is provided with slotted blades 24:- A hollow valve seat 25 is screwed into the outer end portion otthe opening 18 and within the opening 18' is placed a valve ball 26 engaged by a spring 2'? which yieldably retains the valve ball against the seat so that air maybe sucked inwardly but cannot pass outwardly through the opening. 7 The operation is the same as the form of mixer shown in Figs. 1' and 2, the only dilference being that the mounting arms for the wheel are engaged with a carrier secured between the'earbureter and manifold instead of being held in place byla carrier passed through an opening formed inthe wall of the manifold and the valve controlledair inlet is not disposed between the arms.

v tween thus described the invention, I

threaded stem adapted to fit into an opening formed inthe wall of a manifold, bearing arms extending from said base, said base being formed with an air passage between said arms extending axially through the stem a mixing wheel rotatably mounted besaid arms, fastener formed with a threaded bore and having a reduced end to be fitted int'o the opening in the manifold and screwed upon said stem to secure the mounting in the manifolchthe outer end portion'of the fastenerbeing adapted to bear against the outerface ol the manifold, a tubular valve seat screwed into the outer end portion of said bore, a valve ball in the bore to seat against the. inner en'd of said valve seat and a spring in said bore between said ball and stem ,yieldably holding the valve ball in engagement with itsseat.

In testimony whereof I aflix my signature.
