serial No. 352,978.

citizen of the United States, and a resident of' the city of Reading, in the county of Berks and State of Pennsylvania, have invented certain new and useful Improvements in Carbureters for Explosive-Engines, of which the following is a specification. ,k l

My invention relates particularly to carbureters adapted for motor cycle use, and it consists in certain improvements in construction hereinafter fully described in connection with the accompanying drawings and the novel features of which are specifically pointed out in the claim. V

The drawing is a artly sectional elevation of a carbureter emfiodylng my invention in preferred form.

An ordinary spraying device for gasolene or other hydrocarbon liquid, is indicated at 5, located in a central tube 6 of the carbureter and communicating through suitable conduits 7, 8, with a gasolene chamber 9. As shown this central tube 6 rises from a perforated or spoked plate 10 which screws into the lower end of the mixing chamber cylinder hereafter described, and it is loosely surrounded by a partition ring 11 carried by said late 10. This partition rin forms an annu ar outer air-chamber 12 an an annular inner air-chamber 13 both communicating with a lower air-inlet lchamber 14 which is carried by a depending extension 15 ofthe central tube 6.

The mixing chamber cylinder as shown is formed by a lower main ortion 20 and an e former of which is rovided witll a vertically movable cylindrlcal cut-ofi valve 22 in addition to the sprayer 5 and artition ring 11 already mentloned, while t e latter is provided with a rotary cylindrical throttle valve 23 arranged to regulate the volume of fuel gas discharged side outlet 24 therefrom, the particular construction` and coperative arrangement of these parts-as shown, beine' fully described and claimed in my original application, Serial No. 334,368, filed September 13, 1906, of which the present application is a division.

The gasolene chamber 9, as shown, is an annular chamber surrounding the mixing cylinder 20 and formedintegral therewith, the separately formed upper cylindrical uportion 21 being fastened to the lower cylindrical portion 20 bymeans of a suitably secured ange 45 arranged to cover said gasolene chamber.

The su ply of gasolene to the chamber 9 is controlla as usual by a needle valve 50. This valve as shown is mounted in a vertical conduit 51, connected to a sup ly tube 52 and communicating at 53 with t e chamber 9. To pro-vide for nicely adjusting this valve its point is seated ina ring 54 which is adjustable vertically 'n a screw-threaded portion of the conduit 51, while the upper portion of its stem is guided in a screw-cap 55 and its vertical lift is regulated by an adjusting screw 56 as indicated. To provide for the automatic o l eninfr and closing of the valve as required empnloiy7 a lever 60 pivoted intermediately at 61 and aving its short end 62 engaging the collared stem of the valve While lts semi-circular inner portion is carried half way around the mixing cylinder 2O and has its ends 63 arranged to contact with an annular float 64 in the gasolene chamber 9 so vas to be lifted bv the latter when said chamber is pro erly filled, and thereby closing the needle va ve which is normally held open by said lever.

What I claim is y In a carbureter a hydrocarbon chamber with a float therein, an interiorly screwthreaded supply conduit having a lateral outlet to said hydrocarbon chamber and a supply tube connecting end, an exterior y screw-threaded valve-seat ring adjustably located within said conduit below said outlet, a valve seating on said adjustable ring and having a collared stem extending above said outlet, any adjustable stop to limit the opening movement of said valve, and a pivoted lever extending through said outlet, to the valve stem, and operated by said float to automatically close said valve, substantially as set forth.

In testimony whereof, I aiiix my signature, in the presence of two witnesses.

LOUIS P. FOSNOT.
