COMPANY, OF TOLEDO, OHIO, A. GORYORATION OF OHIO GAS GENERATOR INSTALLATION Application 1ed December 13, 1926. Serial No. 154,438.

This invention relates to gas generators or carburetor installations.

This invention has utility when .incorpo rated in entraining or atomizing means for 51 liquid fuel especially as adapted for domestic lighting, cooking and heating purposes.

Fig. 2 is a vertical section through the humidifier and fluid piston device of Fig. l;

Fig. 3 is a section on the line4 IIT- 111, Fig. 2, looking in the direction of the arrow;

Fig. 4 is a vertical section through the gas generator or vaporizer of Fig. 1;

Fig. 5 is a section on the line V-V, Fig. 4, looking in the direction of the arrow;

Fig. 6 is a vertical section through the receiver of Fig. 1;

Fig. 7 is a section on the line VII-VIL Fig. 6, looking in the direction of the arrow; and

Fig. 8 is a fragmentary view in plan of the fan or air pump.

Electric motor 1 is shown as having shaft 2 effective through belt 3 for driving pulley 4 on shaft 5 fixed with bladed drum 6 as an air delivery device or fan designed to have a wide range of capacity for delivering against a constant back pressure to bev developed and maintained by said fan.V From this fan 6 extends pipe 7 upward and then down into vessel 8.

This pipe 7 has upturned multiple `iet termini 9 disposed below and Vithin'chamber 10 fixedly mounted in this vessel 8 by brackets 11, 12, 13. Clamps 14 position the pipe 7 with this chamber 10. Liquid. as water 15, may be in the vessel 8 with free communication through open end 16 as well as port 17 to the interior of the chamber 10. The region of this water 15 within the chamber 10 provides a wat-or piston 18 which, in the normal pump operation, is effective to be depressed to bring the level of the water 15 about the chamber 10 to a desired head for maintained pressure above the port V17. When excessive air pressure is developed within chamber 10 the liquid piston within` said chamber is depressed to uncover port 17 and when this happens the excess air passes through said port and upwardly through the liquid confined between the chambers S and 10. As the port 17 is positioned above the jet termini 9 it will be evident that the relief or escape of excess air pressure is edected without depressing the liquid piston sutliciently to uncover the jet termini 9 and hence humidification of the air delivered by the latter at all times is assured. In practice, the

Vmot-or 6 is so designed that this point of maximum pressure for the water head approximates the bac-k pressure for which the fan 6 is designed. There is ready adjustment below this pressureby the reduction of the head of the water 15 by reducing its quantity. There is accordingly herein an automatic relief valve as asafety device Working effectively as a humidifier.

This device is a simple relief, insuring safety against excess pressure, while automatically maintaining a reserve as a balance for taking care of widely diiferent rates of fuel consumption without fluctuation of pressure as additional apparatus may be used. From this chamber 10 extends `pipe 2O past check valves 21, 22, in duplicate, as one to supplement the other against pressure iiow back` into the chamber 10 from gas generator container 23. This pipe 2O enters this closed container 23 and extends to the lower portion to have jet termini 2e of discharge capacity area approximating that. of the pipe 2O for avoidance of back pressure. The jet termini 9 int-o the chamber 10 are likewise of an' area to take care of the capacity of the pipe 7 at the pressure to be developed normally by the fan (i. These jet termini 2li for y the supply of -air to the gas generator container 23 are submerged below liquid fuel 25, as gasoline, or other volatile liquid of a. suitable character. This container 23 may be charged by the removal of air tight closure cap 26. Cleaning out of this container 23 may occur by the removal of the plug 27 adjacent the bottom. Plug 28 may be rew moved for washing out the humidifier 8, 10.

From the upper portion of this container 23 of the generator extends pipe 29 past check 1 y this pipe 29 to reservoir 32. As there may be condensation in this reservoir 32 such may be drawn off by the removal of plug 33 near the bottom. thereof. In practice, even for plants involving a quite wide range of gas consumption, it may not be necessary or even desirable to include the receiver or reservoiry 32, for the humidifier chamber 10 is a pres-- sure equalizing reserve even as against intermittent operation of the fan 6. However, for a supplement-al reserve, this reservoir 32 is effective and has therefrom gas line to gas consuming equipment as may be desired, as to a hot plate burner 35 having gas flow thereto determined by valve 36. Shutting off this valve 36 checks flew back into the reservoir 32. rEhis does not bring about back iiow from this reservoir 32 into the container 23 iecause the check valves 30, 31, preclude back `flow. However, there is built up, in air chamber 3'? over fuel 25 in the gas generator container 23, such a degree of back pressure that further flow or supply air thereto by the line 2O is checked. This does not mean a back flow into the humidifier, for the check valves 21, 22, in the line 20, prevent such reverse flow.

lf the fan 6 be operating, the delivered air depresses the liquid piston 13 to expose the port 17 and as the fan 6 may continue to operate, such excess of pressure air merely bnbbles off out of the vessel 3 and has entrained therewith no combustible mixture or other conditions which tend to develop any lire hazard. At once the valve 36 is opened, pressure flow from the reservoir 32 may be replenished by the generator 23 andrhumidilier chamber 10 automatically and instantaneously to cut off pressure fluctuation.

TWith the installation of the reservoir 32 and a capacity for the humidilier chamber 10, the motor l may be automatically controlled by intermittent operation instead of being run continuously or selectively as the gas equipment is used. To this end the gas delivery line 34 has branch 33 te pressure responsive bellows 39 elfective as to upper diaphragm Ll0 for rocking lever 4:1 on its pivot bearing 4:2 in tilting vessel Li3 having terminals 44, 45, therein to be submerged by mercury 46 as the pressure in the line 33 falls. This means that electric current supply line el?, as extending to terminal 44, isV thus connected to electric line 4-8 extending to the motor 1 in parallel with electric current supply line 49. There is thus automatically a starting of the motor 1 for operation of the fan 6. As the pressure in the branch line 38 is built up, the bellows 39 operate the lever l1 to again tilt the vessel i3 so that the mercury i6 therein is clear of the terminals 4.4, 45, and this automatic switch is thus opened.

What is claimed and it is desired to secure by Letters Patent is:

1. Apparatus of the character described comprising a humidifier, a gas generator and a gas storage tank connected together in series, with the humidifier delivering to the gas generator and the latterdelivering to the storage tank, a blower functioning to force air through Vthe humidifier to the gas generating tank and to provide the pres sure necessaryfor forcing the generated gas from the generating tank to the storage tank and from the latter to the point of consumption, a motor functioning to drive the blower, a pressure responsive device connected to the gas storage tank and a switch operable by the pressure responsive device to open the motor circuit when the pressure in the storage tank exceeds a predetermined value and to close the motor circuit when the pressure .in the storage tank falls below said predetermined value.
