ARCHIBALD S. B. LITTLE, OF ST. LOUIS, MISSOURI.
[ all whom it may concern:
Be it known that I, ARGI-IIBALD S. B. LITTLE, a subject of the King of Great Britain, residing at St. Louis, State of Missouri, have invented certain new and useful Improvements in Bench- Governors, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.
My invention has relation to improvements in bench-governors for maintaining equilibrium between the retortmain of a gas producer or retort and the main leading from the governor to the pump by which the gas is pumped from such producer or retort.
It consists in the novel details of construction more fully set forth in the specification and pointed out in the claims.
In the drawings, the figure represents a combined vertical section and elevation of my invention.
The object of the present invention is to 1)1'O"1Cl6 a sensitive governor which shall maintain a constant equilibrium between the gas-main and the main leading from the governor to the pump, the governor being eminently adapted for use in connection with producer gas, coal gas and the like, although not necessarily restricted thereto.
Its advantages will be clearly apparent from a detailed description of the invention which is as follows:
Referring to the drawing C, represents an annular sealing tank closed at the bottom between its inner and outer concentric walls a a respectively, for holding a quantity of water (the water level being indicated by dotted line w). Over the inner wall a is passed a bell or gas holder 1, the said bell being suspended from chains or cables 2 passing over sheaves 3, 3 at the tops of the standards or posts a, 4L bolted to the upper flange 5 of the wall a, the outer ends of the cables having secured thereto balance weights WV, V. The bell is guided in its movements and the friction considerably reduced by the rollers 6, 6 bearing against the inner surface of the wall a, and by rollers 7, 7 mounted on brackets 8, 8 carried by the bell, and bearing against the ribs or tracks 9, 9 formed with the standards 4-. Bolted to the upper flange 10 of the wall a is a spider 11 through the center of which loosely passes a stem or rod 12 the upper end of which is coupled to the roof of the bell by a ball and socket joint 13 which allows the Specification of Letters Patent.

rod a free movement in any direction, permitting the same to always hang truly ver- .tically under all conditions. The lower end of the stem 12 is connected to a cross rib r of a cylindrical valve 14 which passes through the chamber 15 of a hollow base or casting 16 coupled to the main 17 leading from the retort (not shown), the valve being guided in its movements by the upper and lower walls of the chamber 15 through which it passes. bottom wall of the chamber 15 into the chamber 0r compartment 18 of the casting referred to, into which compartment 18 the is first discharged. The mouth 19 of the chamber 15 is substantially opposite the compartment 18, and communicates directly with the main 20 leading to the pump, (not shown). The valve 14 is provided with a series of peripheral passages or ports 21 of substantially uniform area terminating in upwardly tapering extensions 21, the extensions being in the main above the partition wall between the compartments 15 and 18, and the ports 21 being in the main within the compartment 18, which first receives the gas coming from the retort. The tank 0 is provided with a drain cock cZ as is well understood in the art.
The operation of the governor may be clescribed as follows: As the gas passes from the retort into the compartment 18 of the base or casting 16 it passes through the tapering extensions 21 of the ports 21 into the chamber 15 thence out through the mouth 19 into the pump main 20, the gas likewise accumulating under the bell or float 1. Should the evolution of gas from the gas main 17 become excessive the increased pressure resulting therefrom will raise the float or bell 1 and the valve 14 suspended from it, bringing the ports 21 opposite the chamber or compartment 15 when the inrush of the gas through these ports of camparatively greater area and capacity will afford instant relief by entering the compartment 15 whence the gas is pumped through the mouth 19 into the pump main 20. On the other hand should the evolution of the gas from the retort become reduced, the bell will fall and bring the tapering extensions 21 into play which as the bell continues to fall will gradually reduce the flow to the compartment 15 and hence to the pump main, and again equilibrium is established, that is to say, the flow of gas into the pump main will always be The valve projects through the' draft on the fuel charge shall be practically constant.
Having described my invention what 11 claim is 1. A as overnor com )risin a sealin b c t: m
tank, a bell or float mounted therein, a base forthe support'of the tank provided with superposed chambers or compartments separated by a partition wall, the bottom chamber leading to a source of gas-supply and the upper chamber to a point of consumption, and a hollow valve having peripheral ports composed of substantially constant and reducing areas operating through the partition between the chambers, the top Wall of the upper chamber serving as an additional guide for the valve.
2. A gas governor comprising an annular sealing tank, a bell or float mounted between the concentric walls thereof, a base beneath the tank provided with intercomiminicating' superposed chambers separated by a partition wall, the bottom chamber leading to a source of gas supply and the upper chamber to a point of consumption, and a hollow posed intercommunicating chambers leading respectively to a gas retort main, and to-a pump main, a hollow valve playing across the partition between the chambers aforesaid and provided with peripheral longitudinally disposed ports of substantially constant area terminating in tapering extensions for establishing communication between the chambers aforesaid, and a stem having a ball and socket joint connection with the bell for connecting the latter to the valve, the top wall of the upper chamber serving as an additional guide for the valve.
In testimony whereof I afiix my signature,
in presence of two witnesses. V
