ran/[En FOR mrnnnanooivrnusrron ENGINES.
Application filed ma 25,
T0 (LZZ whom it may concern:
Be it known that I, Seamus Vnmvn r, a citizen of the United States, residing at Syracuse, in the county of Onondaga and State of New York, have invented a certain new and useful Primer for Internal-Combustion Engines ot which the following is a specification. I
This invention relates to primers for lIl-, ternal combustion engines and has for its object a particularly simple and efficient controlling means for such primer.
The invention consists in the novel features and in the combinations and constructions hereinafter set forth and claimed.
In describing this invention, reference is had to the accompanying drawings in which like characters designate corresponding. parts in all the views.
The figure is a fragmentary view of a V carburetor embodying my invention, the primer being shown, partly in section, and partly broken away, and the electric circuits being also shown diagrammatically. g
This primer comprises generally, a chamber having an inlet communicating with a fuel supply reservoir as the fuel or, float chamber oi the carburetor, also 0116101 more air inlets, a gas outlet, an electrical heating unit in the chamb r, electromagnetic means for opening the valve, an electric circuit having branches connected to the heating unit and to the electromagnetic means, and a switch for opening and closing the circuit. 7 The gas outlet communicates with the outlet of the carburetor above the throttle valve. I have here illustrated the primer as fornr ing part of the carburetor."
1 designates the chamber of the primer which is hereshown as mounted or cast on the side of the carburetor 2. The chamber is formed with a fuel inlet 3 near one end which communicates with a suitable passage leading to the interior of the carburetor or the float chamber thereof and with a gas 2 outlet 4 communicating with a passage 5 leading into the outlet 6.01? the carburetor above the throttle valve 7.
' The chamber 1 isalso provided with one or more air inlets, it being here shown as provided with an inlet 8, 9 near its opposite ends. The chamber 1 is here shown as extending in'a general horizontal direction but inclined slightly toward its receiving end downwardly out of the horizontal; The gas and seating at 1-1 in the outlet.
pro ects upwardly out of the passage and is I Iii-rolled by a switch 1921. Serial no. 472,468;
outlet 4 leads from the upper end portion the chamber and opens throughthe upper tace of a block 1 mounted on or cast on the carburetor in" which block the passage is formed. I
10 is a reciprocally movable valve controlling the fiow through the gas outlet r- This' valve provided with an iron extension 12 which constitutes the? armature ofthe electromagnetic means for lifting the valve 10 from its seat A spring as 13 is provided for normally holding the valve against its seatand from opening by suction,
14 is a heating unit or coil suitably mounted in the chamber 1 and having terminals 15, 16 at the opposite ends of the chamber.
17 are the COllS of an clectromagnet here shown as mounted in'alinement with the valve 10 so that the armature" 12 constitutes the core of'the magnetfcoils. 1 v The spring lgencirclesa rod 18 extending from thejcore 12 coaxially of the coils 1'? at the upper end of the coils, the spring '80 and projecting through the head or disklf) thrusting against the inner sideoi the head I 19 and against-theupper end of the, core 12.
lhecoi'ls 17 are connected in series or in shunt in an electric circuit which is 'con-' When the switch is closed, the current passes through-the heating coil and through the'magnet coils.
, \Vhen starting, the throttle valve is preterably first closed, then the switch 20 is closed to energize the heating unit, and the electro-magnet.
Also, the starting motor of the engine is started. When the star-ting motor turns over the engine, the fuel is drawn into the chamber 1" and heated, vaporized and mixed with air to form a com- 'bustible gas and the gas torn ed passes through the outlet of the carburetor above the throttle and'into the manifold.
.Upon opening of the switch 20, the valve 12 is closed by the spring 13 and the heating unit cut out. As here illustrated, the electromagnet coils are connected in shunt with the heating unit, the terminals 15, 16 of the heating unit being connected to the switch to 'minals by the wires 22, 23 and the magnet coilsibei'ng connected in shunt. with the terminals 15 and 16 of the heating coil by Wires 24, one of which is grounded at 25.
What I claim is:
A primer for internal combustion engines comprising a heating chamber extending in a general horizontal direction ancla heating element extending lengthwise of the horizontal chamber, saitl cliaiiib'er havinga ful inlet and an air inlet at one end of the chamber near one end of the "heating 'ele 10 ment and an air inlet and a gas outlet at the other end of'the chamberand near the other end of the 'lieating element and means for controlling the flow of the mixture out of the chamber. In testimony signed my name at Syracuse, in the county of ()iti'o'n'claga an'd State of New York, this 24th day of May, 1921.
