1`Claim. This invention appertains lto new and useful improvements in valve mechanisms for overhead' tanks.
, v The principal object of the present invention 15 a tank equipped with the valve mechanism. v
Figure 2 is a section on the line 2-2 of liigure 1.
Figure Skis av longitudinal sectional view through the valve and stem.
'20 Figure 4 is a section on-the line 4-4 of Fgure 3.
Referring to the drawings wherein like numerals designate like parts it can be seen that the numeral 5 represents the overhead tank from which depends the down pipe 46, which asis common,vhas theshelter pipe or case 1.
The down pipe 6 extends upwardly through an opening in the bottom of the tank 5 and is threaded to accommodate the nuts 8 and pack-v ing washers 9. The upper end ofthe pipe 5 has a seat for the cone I0. .The cone I0 acts as a guide to bringy the resilient washer II against the upper end of ther pipe 6. This cone guide Ill has the head portion I2, between this head portion I2 andthe cone proper I0 there being formed a circumferentially extending groove I3 for receiving the inner edge of the said washer I I.
The head I2 and'cone I0 has a threadedbore I extending therethrough for receiving the lower l end of the tubular stem I5 and the upper end of the tubular guide I6.
' The top of the tank 5 has a bridge member I'I upon which is mounted the bonnet I8. A barrel I9 extends fromv the bridge II 'downwardly to terminate in close spaced relation above the upper end of the pipe 6. The upper end of this A barrel I9 is disposed through an opening in the bridge I'I and'threadedly engaged into the lower portion of the bonnet- I8. A tube 2B extends longitudinally in the barrel I9 and in spaced relation thereto and terminates at itslower end in a bonnet Zea internally spaced from the external bonnet ISa at the lower end of the tube I9, this bonnet 20a having its lower edge 'scalloped to rest on the floor of the tank. The upper 'end of the tube 20 extends upwardly beyond the upper end of the barrel I9 and threads into the socket 2| at the midportion of the bonnet I8. The passageway through the tube 20 registers with the vertical bore 22 extending vertically in the upper portion of the bonnet I8, and through this bore 22 and through the tube 20 operates the afore- 5 mentioned valve stem I5 which has the ring I6 at its upper end. Numeral 24 represents an overiiow spout extending laterally from the bonnet I8 and the stem I5 has a vent therein denoted by numeral 24a which will always be located in 10 close proximity tothe overflow spout 24.
A post 25 rises from the top of the tank 5 and has the rocking beam 26 mounted thereon with one kend connected to the ring I6 at the upper end of the valve stem I5 while its other end has 15 the depending cable 21 vwhich can be reached from the ground and pulled to elevate the valve unitsy I5, Il and I2.
Obviously, the purpose of the barrel I9 is to prevent ice 28 from interfering with the proper 20 operation of the valve stem I5. 4
Obviously, the o'verow pipe 24 has its discharge end overlying the contents of the tank 5 so that when the pump starts up and the tank is frozen over, water will overow and strike the 25 ice 28 and work an opening 29 therein to break any vacuum condition existing.
Obviously, the purpose of the `tubular valve stem I5 is to vent the tank so that there will be novacuum existing to prevent proper dis- 3 charge of the water down the down pipe 6.
While the foregoing specification sets forth the invention in specific terms,it is to be understood that numerous changes in the shape, size and materials may be resorted to without departing 35 from the spirit and scope of the invention as claimed hereinafter. l
Having vdescribed the invention, what vis claimed as new is: 40
In combination with a tank, an outlet, a. Valve seat at the outlet, a valve operative against the valve seat, said Valve being provided with a tubular stem open at its valve attaching endand atl its opposite end and means for operating the 45 valve stem and valve from the last mentioned end thereof and a tube through'which the said stem is operative, said tube extending vertically in the tank and terminating at its lower end above'the seat and a bonnet mounted at the top of the tank 50 and to which the said tube is attached and an `overow pipe extending from the bonnet at a point above the said tube and a protective barrel depending into the tank around the tube and forming a dead air space between itself and the 55 tube.
