GEORGE nuts, or MILWAUKEE, VIISCGNSI'N GAS REGULATOR Application filed August 15, 1929. Serial No. 386,177.
This invention relates toimprovements in gas regulators. One of he objects of my invention is the provision. of a gas regulator adapted to be lncorporatedin gas lines for regulating the pressure through the line whereby when'tlie pressure accumulates beyond a predetermined degree, the supply will be cut off until the pressure is relieved. Another object of the invention is the provision of a regulatorfor controlling the pressure in a gas line so thata uniform pres ure is provided for use wherever required, and the operation is such that should the use of the gas be cut off, the pressure will automatically. cut off thesupply of gas to the line from which the gas is used. s
A furtherobject of the invention is the provision of a regulator of the above type which is comparatively simple in construction, efficient in its operation and so arranged that it can be readily incorporated in the gas'line through .a gas regulator constructed in ac- I cordance'with my invention;
Figure 2 is a detail section on the line 22 of Figure 1; l r
Figure 3 is a horizontal section on the'line 33 of Figure 1'; Y v g Figure 4 is a detail section on the line4-4 of Figure 7 In carrying out my invention, I provide a cylindrical body member 1, having 21.11111- wardly inclined bottom 2 which terminates in a neck 0 internally threaded for engagement with an inlet pipe 4. The body Which' is provided at diametric points with internally threaded necks 5' are adapted to receive therein outlet pipes 6 which may lead to the source of gas supply.
Within the body 1, I provide an inclined wall 7 the upper edge of which is formed integral with inwardly projecting cylindrical parts 8, thus forming divergent passages 9 leading from the neck 3'upwardly to the cylindrical housings or parts 8. These housings 8 open outwardly through the outer wall 5-;
of the body 1,and this opening for each housing is normally closed by means of a plate 10 retained in place by meansof screw bolts The inner ends of the housings 8 open into thebody l and are internally threaded for re ceiving the guide rings 12. These guide rings 12 are threaded intothe inner ends of the housings 8 and are formed with annular flanges 13. The inner ends of the rings which face the interior of the housings'are provided with raised annular ribs 14 against which the gaskets 15' carried by the closure plates 16 I are adapted to rest for closing the inner ends of the housings v I At the junction of the inclined wall-7, I provide an enlarged part 17 the upper face of which is somewhat flattened to receive thereon the intermediate part 18 of a bearing member. This bearing member is retained in position on the enlarged part 17 by means of screw bolts 19, and extending outwardly from the members 18 are the singularly dis-. posed arms QOWlliCll arefpreferably parallel with the inclined walls 7 and are provided at 1:
their outer ends with perforated ears21.
-'Pivota-lly mounted at one end between the ears 21 are the movable arms 22 having slots 23 intermediate their ones, and the heads 21% a. bore for receiving); the inner ends of'the ad usting' members 25. The ad] ustlng members 25 each comprise a central nut-like body having axially disposed externally threadedL portions, one of which'fits within each of the bores in the heads while the other threaded end of the nut-like members extend within suitable oores formed n the locks 26 carried by the inner faces of the closure plates 16.
Uponeach extension for each nut is adjustably mounted a co1lar'27 which canbe 'ad usted toward'and away from the central 7 body forregulatinglhe movement of the arms 22 sothat closure plates 1.6 will be actuate by various amounts of pressure.
attheir upper ends in each of whichis formed Slidably mounted in the slots 23 are the bolts 28 at the ends of the cross bars 29. The cross bars 29 are arranged upon opposite sides of a head 30 on the lower end of the rod 31. Rod 31 extends upwardly through a flexible diaphragm 32 and has its upper end threaded for receiving the nuts 33 arranged on the rod upon opposite sides of the diaphragm.
In view of the fact that Lhe diaphragm is flexible, it will be necessary to brace the central portion thereof and to this end I provide a plate 3 1 upon the upper face of the diaphragm, and a plate 35 on the lower face of the diaphragimthe nuts 33 being threaded against the outer face of plates 34 and 3a.
The annular outer portion of the diaohragm is positioned between opposed fianges 36 and or, the former extending inwardly from the upper portion of the body 1, while the latter flange is formed at tile lower end of the top 38 of the body. The top portion 38 is also provided at its upper end with an inwardly extending annular flange 39, upon which rests the annular portion of the cover 40. The cover carries a hook-like portion 41 adapted to be engaged beneath the flange 39 to assist in retaining the cover in position.
Furthermore, screw bolts 4-2 are passed through the annular outer edge of the cover and flange 39 at one side of the cover, while at the opposite side of the cover, I provide spaced perforated ears 4-3 adapted to he positioned upon opposite sides of an eye let on a screw bolt 45. This screw bolt 45 passes downwardly through the cover and through flange 39 for retaining the cover in position.
It will. be apparent from the foregoing that the gas from the main supply passes into the housing through the pipe 4, through the passages 9 and through the inner ends of the housings 8 into the interior of the body 1, and as there is no pressure as yet within the body 1, the pressure coming in through pipe 4. will be exerted against the closure valves 16, forcing them open and exerting a downward pull on the diaphragm 32, through the operative connection between the plates 16 and the diaphragm. However, as soon as the pipes 6 have become filled and the gas is not being used as fast as it passes into the body 1, a pressure will be built up in the body, therefore, when this pressure in the body 1 overcomes the pressure from the pipe 4, it will have a tendency toforce the diaphragm 32 upwardly, closing the valve plate 16 and cuttingoff the supply from the inner ends of the housings 8. i
In order to properly seat the closure plates 16, a plurality of feet 4:6 are formed integral with the outer faces of these closure plates. and have intimate contact with the interior of the sleeves 12 for properly seating the do sure plates.
It will be noted that the build-up of the pressure in the housing will force the diaphragm 32 upwardly and through the movement of arms 22, relative to the bars 29, the bolts 28 will operate in the slots 23 for actuating the arms 22.
In order to compensate for the different pressures required within the housing for closingcl'osure plates 16, it will be apparent that the diaphragm 32 can be weighted down in addition to the plate 34 when greater pressure is required for closing the plates 16, thus if a light weight is applied to the upper side of the diaphragm, the closure plate 16 will be operated under comparatively low pressure, but if comparatively heavy weights applied to the upper side diaphragm, it will require considerable pressure for movingthe diaphragm upwardly to close plate 16. From this, it will be apparent that weights are applied to the diaphragm in accordance with the pressure required.
It will be apparent from the foregoing, that I have provided a simple and inexpensive regulator, whereby a uniformpressure ma be maintained in the gas supply line and the device is of such construction that it can be manufactured and placed on the market at a very low cost.
1. A gas regulator including a housing, chambers within the housing communicating with the interior thereof, movable closure plates for closing the inner ends of the chambers, pivotally mounted arms having one of their ends connected to the closure plates, a movable diaphragm,'a rod attached thereto, cross bars carried by the rod and having operative connection with the movable arms for opening and closing said closure plates relative to the movement of the diaphragm.
2. A gas regulator including a housing, opposed chambers in said housing with their inner ends opening into the housing, pi" )tfitl arms arranged within the housing adjacent the bottom thereof having longitudin a] slots,
a movable diaphragm carried by the housing, a rod attached to the diaphragm, cross bars carried by the rod and having pins movable in said slots, closure plates at the inner ends of the chambers and means adjustably connecting the movable arms with the closure plates whereby to open and close said chambers upon movement of the diaphragm.
In testimony that I claim the foregoing l have hereunto set my hand at Milwaukee, in the county of Milwaukee and State of Nisconsin.
