' vanvn Specification of Letters Patent.

Application filed April 30, 1913. Serial No. 764,661. a

To ollwhom it may concern."

Be itknownthat I, Pnrnn J. Doom, a citizen of, the United States, residing at New. York. city, in the county of New York and State of New York, have invented newthe valve body to turn vertically rather than oscillate under the actiomof the float, and constructing the valve body so that the surrounding fluid pressure will have little or no efiect'unon the movement of the body.

Other objects will appear and bebetter' understood from that embodiment of myinvention of which the following is a specification, reference being had to the accompanyingdrawings forming part hereof, in Which:-

Figure 1 is a contracted plan of my invention showing the valve casing in section.

Fig. 2 is a detail plan looking at right angles to Fig. 1 with the float mechanism removed. Fig. 3 is a detail perspective of the parts of the valve body. Fig. 4 is a vertical cross section on the line 4--l of Fig. 1.

The valve herein shown and indicated generally by ads intended for use with such tanks as are arranged at an elevation, whereby to have the'water which they hold,

supplied by gravity to a point situated be low the tank. In this connection the valve 0 serves as governor or controller in that it gradually opens as the water in the tank recedes below acertain predetermined level and closes upon the water column in the tank attaining such predetermined level. In this construction the valve (1 includes a casing which is tapped at its central portion to receive one end of a supply pipe 6, which end portion of the said supply pipe 6 may be disposed either horizontally or vertically in the tank, whereby to support the valve 11 horizontally. as shown.

The casing is designed for receiving the valve body which includes a valve proper 6 and stem sections 7 and 8, a" centering device 9 and a bonnet 10. The valve proper 6 is circular in contour conforming to the cross sectional contour of the interior of the casing 5, and bears on a seat or part1- PatentedOct. e, 1914. I

tionll, as shown. The valve proper 6 and the seat or partition 11 are provided with ports or passages indicated by 12-12 and 13-43. When the parts are positioned as shown in Fig. 1, the ports 12-42 and 13.'-13 register but when the parts are these ports are out of registration. The ad ]acent ends of the sections 7 and 8 of the stem lnterfit and are det achably tied together bysuitable fastening means, such as a cotter pm 14. The centering; head't) operates to prevent wabbling of the valve body and is disposed to one side of the opening for the inlet pipe 4 and in spaced relation to the valve properfi so that the intervening space between the parts 6- and 9 constitutes an'inlet chamber 15 between which andthe tank (not shownl communication is controlled by the valve body 6. The valve proper 6 is yieldinqly held to its seat by the pressure of a spring 16 which surrounds the section 8 of the stem and which also functions as a tig htener for the packing 17 interposed between the centering head 9 and a disk 18. The bonnet 10- surrounds the sec-- turned to the position shown in Fig. 4,- I

tron 8 of the valve stemand operates to vary .the tension on the spring 16, the said bonnet being; arranged in one end of the-valve casing 5 and adjustably connected by screws 19-19 to the said valve casing. The bonnet also functions as a centering device for the section 8 of the stem, one end of which section projects beyond the bonnet and passes through the arm 20 of the float 21, a suitable fastening device such as a setscrew 22, being employed for detachably connecting the arm 20 to the stem. The outlet end of the casing may open directly into the tank or as shown in Fig. 1 and indicated by 23, may be adapted for connection to an outlet pipe indicated by 24 -in Fi,2". 2.

From the foregoing the operation of the device will be largely understood, it being obvious that when in use the parts will be adjusted so as to have the ports 1212 and lit-13 register when the water level descends to a predetermined point and to be out of this turning of the valve body it'will be ob- E Y aliases served that the parts thereof do not operate against the direction in which the fluid pressure in the chamber 15 acts, in fact there is no bodily movement whatever had on wthe Eart of the valve proper 6, hence there will e reqnired but a small amount of pressure on the part of the float 21 to turn the valve body.

It will, of course, be understood'that the valve herein shown may be used in connec tion with any apparatus desired to be controlled by a governor. For instance, a steam pamper-ranged for liftingliquid to an elevated tank. When used in this connection it will be observed that the supply of motive fluid to the pump when the valve is connected in the steam line, maybe controlled by the rise and fall of the water level in the tank in which the valve is arranged. Where it is desired to have the valve operated other than by the rise and fall of a water column and such as by fluid pressure, the float 21 may be dispensed with and a diaphragm substituted in lieu thereof, in which connection the diaphragm will be arranged in the fluid pressure line and operate under the rise and fall of thefluid'pressure.

i What is claimed as new is:

A; valve comprising a casing having an inlet and an outlet, an apertured partition located in the casing between the inlet, and outlet, an apertured valve rotatably and slidably mounted in the casin and having a stem section, a stem attache .to said stem section and carrying a head which fits snugly and slidably in the casing at the opposite side of the inlet from" that at which the outletis located, a bonnet attached to the casing and through which said stem passes, a packing located in the casing against the head, a disk located against the packing and a spring interposed between. the disk and bonnet.

In testimony whereof I aflix my signature in presence of two witnesses. p o PETER J. DUGAN. Witnesses:

JOHN A. DoNEo'AN, GEO. A. Emma.
