Application filed January 31, 1927, Serial No. 164,941, and' in Canada December 16,1926.A

'lhis invention relates to valves and particularly to a construction for use as a pumpy provide an elevated! valve seat having a sediment chamber voutward-ly of the regular travel of the water through the valve, so that any sediment will not be permitted to lodge' on the yval-ve seat and thus prevent a proper fitting vof the valve against the same.

A further' object is to provide an elevated valve seat having af sediment chambersurrounding the same', the bottom of the sediment chamber being considerably lower than the valve seat. v

A further object is to provide an elevated valve seatadapted to' be used as a pump va-live when used in pump construction, as a footvalve on the-end of al suction pipe or as a verticalcheck valve where a pipe is cont'inued below the usual valve.

@ther objects and' advantages of my invention will become apparent. ensuing a perusal ofv the'follow-ingspecification read in conjunction with the annexed drawings', in which: 4 y

Fig. is-asectional viewl showing the preferred embodiment of my invention, when usedas a foot valve on the' end of a suction pipe.

Fig. 2 is a sectional view of the preferred embodiment when used as a vertical check valve between two lengths of pipe.

Fig. 3 is a modified form of a base meinber embodying the ring member integral therewith.

Like numerals of reference ydesignate corresponding parts throughout the different views.

Referring more particularly to Fig.k 1, the numeral 3 indicates a head preferably having a body portion of cylindrical formation. Its upper end is formed inwardly and prolvided with an open end portion 4 threaded on its inner circumference. The lower end of the head 3 is provided with the outwardly directed flange 5. 6 indicates an `upper end annular ring, preferably having an outercircumference of the same size as the outer circumference of the flange 5. Upwardly from the inner edge of the ringf6, l provide a. cylindricaly member 7. The height of this cylindrical member 7 may be varied considerably-accordingto the use to which the valve is to be subjected. 8 indicates a base member-preferably having an outer circumference of the same size as thev annular ring 6 and flange 5. Centrally of this base member 8, I provide an upwardly extended boss 9, around which are located spaced openings 10. If desired, this boss 9 may extend both upwardly and downwardly from the base member, as shown in Fig. 3. Between the flange 5 and the annular ring 6, I' provide a gasket or washer 14, which may be made of any desired material commonly used for this purpose.

. The boss 9 is provided with a central vertical openiiig yas at 15, in which a stem4 16 is adapted to .be reciprocally mounted. This stem 16 will act as a support and guide for properly seating a valve disc, hereinafter mentioned. The upper end of the stem 16 is provided with an enlarged head 17, which 'preferably has an annular `outer circumference and its upper surface convex. Positioned under the yhead 17 and tted on the stem 16 is a valve disc 18, preferably having an outer annular circumference parallel with the outer annular circumference of the cylindrical member 7 .v 19 is a jam nut threadedly Aengaged on the stem 16 and adapted to tighten thevalvedisc 18 against the'under face of the head 17. The lower end of the stein 16. isr threaded tol receive the nut 23 near its lower extremity. A cotter pin 24 is fitted through the stem 16 under the nut 23, so as to prevent the nut 23 from coming disengaged from the stem 16. By lhaving this nut 23 positioned on the stem 16, the stem will be retained in the boss 9 against disengagement therefrom.

It will be noted from the drawing, Fig. l, that the under face of the valve disc 18 will normally rest on the upper flat face of the cylindrical member 7 which will act as a valve seat. If desired the upper end of the cylindrical member 7 may be iianged inwardly to provide a greater seat capacity when found necessary. It may be found to be of advantage to have the seating face, at the of the cylindrical member 7, tapered with the outer or inner edge slightly 'base 8 and the annular flange21',-I provide registering openings through which the bolts 11 are fitted, which bolts 11 when tightened into position by the nuts 12, will retain these parts in fixed position as'shown in Fig. 1. Vhen the-valve is to be used as a foot valve, this receiving chamber 1s preferably of a bowl yshape formation and provided with a number of spaced yopenings 22, through which' the wateror other fluid may enter. In having these openings 22 of a pre-deter mined size, this receiving chamber will act 'as a strainer' and will not permit any undesirable foreign matter to be sucked into the valve. y

Referring more particularly to Fig. 2 of the drawings, it will be noted that the same construction shown in all the various element-s, with the exception that the receiving chamber 20 is of a different formation. This receivingchamber 20, in Fig. 2 of the drawings, is preferably formed of a similar size and style'as thehead 3.

y Its lower end is adapted to have threadedly engaged therein a pipe as shown. When this type of receiving vchamber is used, a second gasket or washer 14 is used between the flange 21 and `thering 6 so as to make a water tight fit therebetween. K p

Fig. 3 shows a modified form of base member '8 which embodies the annular `ring 6. The cylindrical member 7- being integral Awith'thebase 8, which will eliminate the necessity of two fittings for certain requireA ments where this form may be found desirable.

`Throughout the specification'fand in the drawings, it will be noted that I refer to the body portion of the headB and the member 7 as being cylindrical in formation. I do not wish to limit myself to having these parts cylindrical, as .it mightbefound advantageous tovhave them square, oval or kof any desired formation, in which case, the cor-operative parts would be shaped to work in connection thereto. l

The foregoing specification and annexed drawings discloses thepreferred embodiment of my invention,.but it is to be ,understood that minor changes may be resorted to in the commercial adaptation of myinvention without departing from the scope ofthe invention as hereinafter claimed.

l/Vhat'I claim as new is v 1. In a valve comprising a kcylindrical member having an annular flange protrud-` ing outwardly from its inner-.,end; `a valve adapted to be normally seated/on theouter end of said cylindrical member; a boss, supported.` internally of said cylindrical .mem-

ber, through which the stem of said valve reciprocates and the flange of said cylindrical member being fixedly secured between the receiving chamber andthe head portion of apump construction.

2*. In a valve comprising a cylindrical :1-

member having an annular flange protruding outwardly from its inner end; arvalve adapted to be normally seated on the outer end of said cylindrical member; a boss, supported internally of said cylindrical mem-v` ber but independent thereof, throughl which the stem of said valvereciprocates and the flange of said cylindrical member being fixedlysecured between the receivingv chamber and the head portion of a pump construction.
