Auron/Atrio PRESSURE-GOVERNOR.
T o all whom 'it may concern Be it known that I, RANsAnmER J. JENKs,
a citizen of the United States, and a resident of Lewiston, in the county of Nez Perce and State of daho, have invented a new and useful Automatic Pressure-Governor, of which the following is a specification.
My invention is an automatic governor for use on gas generators wherein a vacuum supply is employed for drawing the gas fromthe retorts to the hydraulic or service main. The principal obj ect of the invention is to provide an automatic governor which will prevent excessive vacuum draw on the retorts and at the same time control the gas pressure from the retorts to the hydraulic main.
The invention further provides an automatic pressuegovernor for gas generators including an automatic governor to be associated with a stand-pipe of a gas retortfor controlling the flow of gas from the retort to the service or hydraulic main, and to prevent vacuum draw on the retorts after the fuel charges therein have been spent or partially spent. Thus the retorts of the gas generator may be individually controlled and thereby obviate the necessity of shutting downthe entire plant while any one or more of the retorts are being recharged. f
Further, the invention provides an automatic governor that will be operated to allow ygas to liow into the service main after sulficient gas pressure has been generated and reversely, shall be operated to cut off communication Vbetween the service pipe and the re- Y tort when the-gas pressure has fallen, rlhus,
gas below a relatively low volatile quality cannot flow into the service main and thereby lower the quality of gas in the service main. y
It is also an object ofthe invention to pro- -vide a gas pressure governor that may be readily installed on the usual dip pipe Of the gas generating retort. l
The invention further contemplates a gas pressure governor, which is of simple construction and positive 'in operation.` y
With the preceding objects and others that may be hereinafter pointed out, the invention consists in the novel combination of elements,construction, operations and specific details to be fully `setLforth and claimed, the
invention being illustrated Figure l is a fragmentary end elevationof a gas generator having a plurality of lre- Speccaton of Letters-Patent. f Patgntd Maly 3, 1921 Y Application mea Jum-T a V1920. seriai No. 387,399. Y l

Fig. 2 is a vertical sectional view taken' on line 2 2 ofrFig. 1, the dotted line illustration showing weight .Fig 3 is a fragmentary vertical sectional i view of one of the dip pipes and the vpressure control valve associated therewith; Y
Fig. 4 is a detailed view of the valve;
Fig. 5 is an elevation of a pipe tting emp bodied in the invention Fig. 6 is an elevation taken at right angles to F ig. 5;

Fig. 8 is a similar view of another modifi-- cation.
Referring in detail to the drawings whereim like characters ofreference designate' corresponding parts :throughout the several views, the numeral 5 designates a conventional gas generator and includes a plurality .of retorts 6, each of which has a vertical stand-pipe 7 leading from one end thereof. The usual hydraulic or service main'is designated at 8 and extending into this main`8 is a plurality of dip pipes 9, each of which has communication with one of the stand-pipes a modiied type ofvcounteris a view partly in vertical'cross4v 7 by a connection 10. Also communCltlg 'i with the service main Vis the usual vacuum Vconduit which is in communication with any source of vacuum supply (not shown). This f structure is one type of gas generator and the parts thereof are referred .to andl illustrated to illustrate my gas pressure governor, one. of which is associated `with the Vdip tube of Although' several retorts and Y each retort.
their dip tubes are shown, each is equipped with a'governor ofidentical construction.
The invention, as reduced to practice, `consists of a T-tting 11, the shorter legvl of which is of the saine diameterY as the dip tube and kis disposed between-the pipe'sec- Y tions formingthe dipptube, this leg l being longitudinally bulged at one side as designated at 12.
Secured to the flange 13 of aI laterally or y v is provided with a removable cover 18 while the outer end of the horizontal leg of the fitting 11 receives a threaded plug 19.
Receiving the vertical pipe 16 and vertij cally movable in the liquid tank 17 is a pressure actuated bell 2O through which a rod 21 passes and is secured thereto by jam nuts 22 threaded upon this rod at opposite sides of,Y
theupper wall of the bell. This rod 21 is vertically movable through the pipe 16 and projects a substantial distance above the cover of the tank 17. A bracket or standard 23 is fixed to the tank 17 to the upper end ofrwhich aflever 2a is pivoted at its center, the latter having one end pivotally connected with the upper end of the rod 21 while a rod 24 carrying counterweights 25, is suspended from it opposite end, the counterweights being such as to normally balance thebell 20 as illustrated in Fig. 2.
The lower end of the dip tube is reduced in thickness Vand affords an annular shoulder 26 which extends at a slight obliqueangle with respectto the horizontal, adapted to close this end of the dip tube a valve designated inits entirety at 27. This valve includes a dished or concave bottom 28 merging into aninwardly disposed'frusto-'conical member 29 at its center. Formed with the Abottom, 28r at its outerk edge is an upstanding annular rim or wall 30 adapted to receive the reduced endrof the dip tube whenv theV valve is in closed position. The rim or wall 30 gradually increases in height from one point to a point diametrically opposite and v in the same plane as the obliquely disposed annular shoulder; thus a gradual seal or closing of the valve will be effected.
. l A relatively long stem 31 is rigid with the frusto-conical member 29 and has'its upper end pivote-cl to a horizontally disposed lever 32 adjacent its inner end which is pivoted adjacent its'opposite end bearings 83 efrtending laterallyV within the horizontal of the fitting 11, this end of the lever being pivoted to the lower end of the rod 21. The inner end of this lever is movable in the depression afforded by the bulged side 12 of the fitting 11.
In operation, the gas generated in the retorts, passes up the stand-pipes and into the dip tubes from where it passes into the horizontal leg of the'iittings and rises in the bell 20. When sufficient pressure has entered between the water-head and bell to overcome the weighted end of the lever11 to lower the free end thereof which causes the valve 27 to move away from the end of the dip tube to permit the vacuum in the hydraulic main to draw on theretorts.
yconnected with a link 35 having its opposite end pivoted to a leverY 36 pivotedv at its center and to the ends` of which operating cables 37 passing around pulleys 38 are connected.
Another modified embodiment of the in- I vention is illustrated in Fig. 8. In this construction, a diaphragm 39 is arranged adjacent one end of the horizontal leg. of the fitting 11 and extending through this diaphragmV andrconnected thereto is an operating rod 10, from the outer end of which weights 41 are suspended. The opposite end of the rod 40 is connected. to a bell crank lever ll2 having operative connection with the valve stem `31. It will be obviousthat vacuum from the hydraulic main will move the diaphragm inwardly to rock the bellV crank lever, thereby lowering the valve. Upon pressure from the retortsfovercoming the vacuum, the diaphragm will be returned to normal position, thereby rocking the bell crank lever to raise the valve. y
It is to be understood that the formsof my invention herein shown and described are to be taken as preferred examples of the same, and that various changes inthe shape,
size'and arrangement of parts may be re-V g sorted to withoutl departing from the spirit of the invention or the scope of the subjoined claims.
