Specification of Letters Patent.

Patented June 9, 1908.

Application filed October 4, 1907. Serial No. 395,848.

To all 107mm. it may concern:

Be it known that I, (oRxELiL's P. KEN- Ton, of Anderson, county of Madison, and

State of Indiana, have invented a certainj new and useful Gas-' Regulator; and I do hereby declare that the following is a full, i clear, and exact description thereof, reference being had to the accompanying drawings, in which like letters refer to like parts.

The object of this invention is to improve the Construction and operation of gas regulators whether for high pressure service or low pressure service.

One feature of the invention consists in a peculiarly balanced valve mechanism, two valves being mounted on opposite sides of a diaphragin-controlled lever, so that the pressure of the gas on the high pressure side of said valves will counteract each other.

Another feature of the invention consists in the provision of a rocking valve or one thatis automatically adjustable to its seat.

Another feature of the invention consists in the means for mounting the valve-controlling lever.

Another feature of the invention consists in providing means for preventing any particles -of mercury from being deposited upon the diaphragm. Heretofore mercury particles have been deposited upon the diaphragm gradually so as to materially alter the action of the diaphragm and the operation of the device.

This invention prevents the mercury loadin the diaphragm.

he nature of the inve'ntion'will be understood from the accompanying drawings and the following description and claims.

In the drawings Figure 1 is a central vertical section through the device in line with the valve-actuating lever. Fig. 2 is a horizontal section on the line 22 of Fig. 1, parts.

being broken away.

In detail the cas ng of the device is formed of a bottom portion 10, top portion 11, a

'mercury seal portion 12, which when united,

! bined with the diaphragm plate 23 above and the plate 24 below secured by the screw 25. 5 The diaphragm is downwardly pressed by a spring 26, the tension of which is controlled 3 by a screw 27. From the plate 24 cars 29 extend downwardly that are pivoted to one end of a valve lever 30, which is fulcrumed on l a pin 31. The longer end of said lever lies in the diaphragm chamber 18 and the short 5 end extends into the low pressure chamber l 16. These two chambers 16 and 18 are in conummication with each other. One end of the pin 31 projects into a socket in the inner side of the casing 10 and the other end of the pin abuts against a screw 32, whereby said pin is held in place or removed.

Into the small end of the lever 30 a screw valve stem 33 extends that has a nut 34 on and fits in a correspondingly oval-sha ed recess in the upper part of the substantia ly flatfaced valve 36 so that the valve can'rock or have some movement independently of the valve stem. A screw 37 enters the bottom of the valve and screws up against the oval end 35 of the valve stem so that the relation between the valve and valve stem can be ad- 40 is in a position the reverse of the valve 36, but has a similar oval-shaped socket for the oval-shaped lower end 41 of a valve-stem 42 that is mounted in the lever 30 on the side of The valve 40 has a similar screw 37 for adjusting it on its valve seat. There is an openmg in the casing below the valve 40 that IS closed by a lug 44 to render said valve accessible. 'T e artition 45 in the mercury chamber is hel in-place by, a screw 46 that screws into a partition 47 which separates the chambers 18 and 20. A projecting shell 48 extends from said partition 47 so as to partially check any particles of mercury that might be blown out from the mercury chamber. Such particles as would pass this shell 48 would go up through the passageway 50 into the chamber 21 that communicates with the low pressure chamber above the diaphragm by a passageway 52. The upper end of the chamber 21 is closed by a plug 53. The lower end of the chamber 21 tapers downwardlyso that such mercury particles as would enter said chamber would gravits upper end, and the lower end 35 is oval justed and predetermined. The other valve.

the pivot 31 opposite the other valve stem 33.

ity return and drop down into the mercury chamber 19. 59 s an opening for the outside air.

What I claim as my invention and desire to secure by Letters Patent is:

I. A gas regulator provided with a diaphragm and a low pressure chamber below the diaphragm, an atmospheric chamber above the diaphragm, an outlet passageway leading from the low pressure chamber that is in communication with the chamber above the diaphragm, a mercury seal between the lowpressure chamber and the outlet and below the passageway to thechamber above. the diaphragm, and means for preventing the mercury from passing into' the chamber .above the diaphragm and depositing upon the diaphragm.

2. A gas regulator provided with a diaphragm, a low pressure chamber below the diaphragm, an atmospheric pressure chamber separated by a partition from the low pressure chamber, a mercury seal between said two chambers, an atmospheric pressure chamber above. the d iaphragm, and a mercury catching chan'iber above said first mentioned atmospheric pressure chamber and discharging downwardly therein and in communication with the chamber above the diaphragm, whereby said mercury catching chamber will catch all mercury particles that may be blown from the mercury seal and prevent the same from entering the chamber above the diaphragm and being deposited on the dia-' phragm substantially as set forth.

In witness whereof, 1 have hereunto affixed my signature in the presence of the witnesses herein named. V
