S FOB SUPPLYING AIRTO GAS-ENGINES.
To all whom it may concern:
Be it known that I, CHARLES L. KURTZ,
and useful Improvement in Means for Supplying Air to Gas-Engines, of which the herein shown and described, the features of .closed position when the completely retarded. 110
lowing is a specification.
In starting an ordinary automobile gas engine or in climbing steep grades with the automobile the supply of gas should be richcr than for ordinary operation. When im engine has become warmed after starting it is important, in the interest of economy and smooth operation, that the gas be aerated by an auxiliary supply of air according to variations in the amount of fuel admitted, that is if the fuel be increased the air should be approximately proportionally increased and conversely.
The object of the present invention therefore is to. provide improved means whereby an auxiliary air supply for the gas intake or manifold of an explosive engine can be automaticallv increased to conform to an increase in t is volume of the gas supply up to "apredetermined point which is about the limit used in ordinary work and beyond that automatically diminished or practically excluded with an increase inthe gas supply.
The invention is embodied in the example novelty being finally claimed.
.In the accompanying drawings Figure 1 is a. detail chiefly in section showing the mechanism for regulating the air intake, the controlled valve being in its gas throttle is Fig. 2 is a side elevation of the air intake devices showing the position of the controlled valve operating levers in their. positions when the valve is closed or when the gas throttle is advanced to beyond the limit of the ordinary running position.
Fig. 3 is a similar view showing the controlled valve operating levers in their positions when the valve is fully opened.
Fig. 4 is a plan view showing how the air valve operating levers are connected for operation with the gas throttle or control shaft. y
In the views 5 designates a fraction of the manifold ofthe gas engine of the Ford car. Tapping into the manifold 5 is the auxiliary air supply pipe 6. This Patented June 4t, 1918.
Application filed December 20, 1917. Serial No. 208,041.
From the foregoing it will be observed that the regulation and control of the auxiliary air supply to suit the described varying cpnditions is rendered automatic and by narygas control lever.
To heat the auxiliary air the intake pipe 11 can be formed as a coil 11 to encircle the engine exhaust 32 as illustrated in Fig. 1.
The forms and arrangement of the parts can be varied without departing from the gist of the invention as claimed.
What I claim is 1. The combination with a gas engine and a gas supply control therefor, of an auxiliary air supply means including a valve, and means actuated concomitantly with the actuation of the gas supply control for increasing the supply of auxiliary air within a predetermined limit; and beyond said limit reducing the said air supply.
2. The col'nbination with a gas engine and a gas supply control therefor, of an auxiliary air supply means including a valve, and means actuated by the gas supply control for increasing the supply of auxiliary air within a predetern'iined limit and beyond said limit reducing the said air supply.
3. The combination with a gas engine and a gas supply control therefor, of an auxiliary air supply means including a valve, and means actuated concomitantly with the actuation of the gas supply control for 'increasing the supply of auxiliary air within a predetermined limit and beyond said limit excluding the said air supply.
4. The combination with a gas engine and a gas supply control therefor, of an auxiliary air supply means including a valve, and means actuated in one direction by the gas'supply control for increasing the supply of auxiliary air within a predetermined limit and beyond said limit reducing the said air supply.
5. The combination with a gas engine and gas supply control therefor, of an air supply for the gas, means including a valve, means for reciprocating said valve including a spring and a cam, said cam movable in one direction for causing the movement of the valve in opposite directions and means connecting the cam with the gas supply control for actuating the cam, substantially as described.
6. The combination with a gas engine and gas suppl Y control therefor, of an air supply for tie gas, means including a valve,
means for reciprocating said valve including CHARLES L. RU RT Z.
