Sept- 21, 95 J. L. PEGLER DISCHARGE VALVE FOR CISTERNS Filed Aug. 8, 1952 Patented Sept. 21,- 1954 DISCHARGE VALVE FOR CISTERNS Joseph Leslie PeglerfBeecroft, near Sydney, New South Wales, Australia, assignor to Lockair Pty. Limited, Sydney, New South Wales, Australia, a corporation of New South Wales Application August 8, 1952, Serial No. 303,306
Claims priority, application Australia July 28, 1952 Claims.
This invention relates to discharge valves for cisterns and more especially has reference to devices of that description known as Sucker valves.
Valves of that description at present in use embody a flexible suction cup which is arranged on operation of a hand lever, to be forced down onto the valve proper and to lift the latter for a suiiicient length of time to allow water contained in the cistern to flow freely down the discharge pipe thereof underthe influence of gravity.
The known arrangements call for a system of links and/or levers, and as some of those components are relatively long the mechanism as a Whole does not always operate satisfactorily. Moreover in many of the known arrangements the suction cup cannot easily be flattened suihciently to create that degree of vacuum necessary to lift effectively the valve proper, with the consequence that repeated attempts must be made to discharge the cistern, or such attempts are not persevered with. In the case of flushing cisterns that neglect is, of course, objectionable.
The present invention seeks to overcome the recognized defects of existing Sucker valves, and at the same time aims at providing arrangements for their operation which will render such valves more efficient and less costly than those now in use. p
The invention is characterized chiefly in that the beforementionedsuction cup is arranged to be pushed into direct contact with the upper surface of the reduced and pliant marginal portion of a flexible disc designed to bearagainst the seat of a discharge fitting which isintended to be affixed in the floor of a cistern.
In order however that the invention may be clearly understood and readily carried into practical eflect reference is now made to the accompanying drawings wherein:
Figure 1 shows a transverse vertical section of portion of an ordinary flushing cistern with a dis charge valve embodying the present improvements in their preferred form; and
Figure 2 is an enlarged view at right angles to Figure 1, and taken on the vertical plane 22 indicated in that figure.
Figure 3 is a sectional plan taken on the horizontal plane 3-3 of Figure 2.
According to the invention as illustrated the improved discharge valve as a whole is installed in the floor 5 of an ordinary flushing cistern 6. The head I of the valve proper is of a relatively heavy hard-setting composition of known type such as plaster, cement or the like, and said head I has applied or aflixed to its underiace a disc 8 of rubber or other appropriate flexible material. This disc 8 has a reduced pliant marginal portion 9 which extends beyond the perimeter of the head I. I
A valve stem [0 with its head ll embedded in the head I is slidable vertically in a spider l2 which is moulded integrally in a discharge fitting i3. This discharge fitting I3 is preferably of one of the well known hard setting plastic materials and is secured in the floor 5 with the aid of a back nut l4 and gasket [5. The upper edge of the discharge fitting 13 constitutes a seat It for the disc 8.
Above the head I of the valve proper there is an inflexible cup I! also preferably of one of the well known hard setting plastic materials. In fact this cup I! can conveniently be employed in the first instance as amould for the head I so that the one will be the complement of the other.
The cup has one or more bleed-holes H3 in its skirt and is aflixed to the lower end of a vertical stem IS. The upper end portion of this stem I9 is connected to the outer end of a lever 20 which is pivoted to a bracket 2!. This bracket 2| lies against the inner face of wall 22 of the cistern 6 and is held in position by a push-button fitting 23 led into said wall 22.
A push-button 24 loaded by a spring 25 is slidable in the mouth of fitting 23, and a stem 26 at-' tached to or integral withthe button. 24 has one end of a link 21 attached to its projecting end 28. The other end 29 of link 21 is connected to the lever 20. V i
Any suitable form of inlet fitting may be mounted in the cistern 6 to supply water automatically after each flushing. The fitting 39 shown in Figure l is of a known pedestal type having a valve encased in its head 3! and arranged to be opened when the ball float 32 falls with a receding water level.
Assuming that the cistern 6 has been filled automatically to the level indicated by the broken line 33 in Figure 1, flushing isinitiated by pressing in the push-button 24.
Movement of the push-button 24 is transmitted to the lever 20 through link 2'! and, being multiplied by the leverage, is used to force the cup I! downwards until its rim presses intimately all around, onto the flexible marginal portion 9 of the disc 8.
The push-button 24 can then be released and it will be returned to its normal position by spring 25. At the same time the spring 25 will raise the lever 20 through the medium of link 2i and consequently the cup I! will suck up with it the valve proper.
Poised above the seat 16 the valve proper will be suspended for an interval until sufiicient water has seeped through the bleed-hole or holes l8 to break the suction exerted on the valve proper by the cup [1. The interval is long enough to allow sufficient water torush down through the discharge fitting I3 and effect flushing below.
It will be appreciated that while the construction illustrated incorporates a spring in immediate association with the push-button 24 a compression spring could be arranged say below the lever 26 to elevatethe cup I! after it has been forced down by pressure on the push-button 24, or some other obvious alternative could be adapted.
I claim:
1. A discharge valve for cisterns comprising in combination a discharge fitting provided with means whereby it can be secured in the floor of a cistern, a valve proper having a head with a flexible disc below said head, said disc having a reduced and pliant marginal portion extending beyond the perimeter of said head, an inflexible cup suspended above said head, and a push-button located in a wall of said cistern, said pushbutton being connected to means whereby 'the rim of said cup can be forced against the reduced and pliant marginal portion of said disc to lift by suction the aforesaid valve proper.
