Description
March 29, 1955 M. A. GEHNER CARBURETOR DE-ICER Filed Jan. 29, 1952 FIG.2.
INVENTOR. MAURICE AGEHNER BY V ATTORNEY.
United States Patent 2,705,135 CARBURETOR DE-ICER Maurice A. Gehner, St. Louis, Mo., assignor to Carter Carburetor Corporation, St. Louis, Mo., a corporation of Delaware Application January 29, 1952, Serial No. 268,795 6 Claims. (Cl. 261-41) This invention relates to carburetors for internal combustion engines, particularly of the automotive type and consists in novel means for dislodging ice formations in the vicinity of the idle port and throttle valve.
The fuel and air which emerge from the idle port in a carburetor, and which pass the partially closed throttle In the accompanying drawing which illustrates the invention:
Fig. l is a vertical transverse section of a carburetor embodying the invention.
Fig. 2 is a similar view showing the lower portion only of the carburetor, but with the throttle valve in slightly open position.
The carburetor conduit 5 with an air which is mounted a pivoted butterfly choke valve 7 controlled by any suitable manual or automatic mechanism. In the lower part of the mixture conduit there is a butterfly throttle valve 8, whcih is manually controlled by the usual lever and linkage parts (not shown), and the lower extremity of the carburetor barrel is provided with a flange 9 for attachment to the engine intake manifold.
Adjacent the mixture conduit there is a constant level chamber 10 enclosing the usual level controlling float 11. In the lower part of the constant level chamber is a main metering orifice element 12 through which fuel is supplied to upwardly inclined, main fuel passage 13 openough a nozzle 14 into primary venturi tube 15.
fuel is supplied through a metering tube 16 communicating with the main fuel passage, posterior to orifice element 12,, and idling passages 17 and 18 opening through ports 19 and 20 adjacent and posterior to the edge of throttle valve 8 when closed. An idling mixture adjusting screw 21 cooperates with lowermost port 20.
A cross passage 22 is provided in the wall of the mixillustrated has a downdraft mixture inlet horn 6 at the upper end in 2,705,135 Patented Mar. 29, 1955 is closed at its outer A small piece of resilient plug 23 through port 19 and into the hand wing of throttle valve 8 so as to be shifted thereby, as the throttle valve approaches its closed position, to dislodge any ice which may be formed in or about the port. Of course, port 19 will be constructed to supply the proper quantity of idling slight space occupied by wire 24.
As the throttle valve is opened, as in Fig. 2, wire 24 returns to its original configuration by its own resiliency and again sweeps port 19, an advantage, since ice may form or re-form about the port during idling operation, due to clearance provided between the edge of the throttle disk and the mixture conduit wall for the supply of air to the engine even at normal idle position of the throttle.
A spring strip or other shiftable element may be substituted for the wire 24 and the manner of mounting thereof may be varied, as well as the shape and extent of the element.
The invention may be modified in spects as will occur to those skilled in the art, and the exclusive use of all modifications as come within the scopel of the appended claims is contemplated.
