SANITARY FLSI-IING- DEVICE.
Application filed January T0 all iii/0m t may eminem.'
lic it known that lilanconwr TenL'roN Pirintrrrm a subject et His Majesty the King ot Great Britain, andcitizen of the Coinn'ionwealth ot Australia, residing` at lWatson Avenue7 Tooxal;7 in the State oit South Australia, Commonwealth ot Australia7 has invented certain new and useful Improvements in Sanitary Flushing De" vices7 of which the following is a specification.
llfly invention relates to an improved sani tary flushing device, the object ot the saine being to provide a device -lor the purpose indicated which shall be comparatively simple and inexpensive in construction and is controlled by an air valve7 the associated parts ot the ;onstruction being somewhat similar 'to those which are at present in use, except that Vthe lushing cover device does not rise and tall iisually the case, thus enabling` the cistern to be protected or screened by wire netting or other means.
In carryingl niy invention into effect I use a suitable cistern wherein the usual water supply is iitted and controlled by a floating ball valve. The cistern is turnished with a tubular shaped outlet which is surrounded by a concentric walh and above this part ot the construction I provide a cylindrical shaped cover having a concentric inner wall, the arrangement being such that when the parts are in 'working position the concentric inner wall ot the cover is external to the tubular oiitlet and the outer wall ot' the cover is external to the inner cylindrical wall. as an air loch and is connected by means oi a pipe or tube with air release apparatus, and a snitter pipe is tilted in the cover and connected with the upper portion or air space ot the appliance. The intlowing water which conti-oiled by the action ot the tlfmtiugiA ball valve enables the water to rise in the cistern and to charge the space enclosed by the cover up to a predetermined level where it is retained until released by the release ot air and thus discharged through the outlet pipe.
But in order that my invention may be more clearly understood I will now proceed to describe the same by aid et the accompanyiing` illustrative drawings wherein Fig. l is an isometrical view of the cistern and its associated parts in part section.
Fig. 2 is a sectional elevation ot a cylinn n um The cover which is stationary servesy Serial No. 527,210.
drioal cover as manufactured from cast metal.
Fig. 3 a sectional elevation of portion ot' the cistern as made from cast metal showing the outlet and its concentric wall.
Fig. lis a plan oi a portion of the cylindrical cover showing modified arrangement :for fittingthe snii'ter pipe.
Fig. 5 is an outline diagram illustrating` the approximate water levels when an air lock has been formed.
In each ot the illustrations similar letters ot reference are used to denote similar or corresponding parts wherever they occur.
In the drawings a is the cistern which may be inainitactured from sheet metal, earthenware, or cast metal and is titted with a tubular shaped outlet pipe b, the extension of which is continued above the iloor ot the cistern as indicated at o, and is surrounded by a concentric inner wall of similar height as shown at (Z. These portions may be constructed trom cast metal substantially as illustrated in Fig. 3 of the drawings, the outlet pipe l) of Fig. l being screwed or otherwise attached to the underside of the cistern as will be readily understood upon reference to Fig. 3 of the drawings. Y
rfhis portion of the structure is enclosed by a flushing cover preferably of cylindrical shape the top portion ot which is shown at e, and the outer wall j" of the cover is ot suitcient diameter to enclose the correspomling internal wall in the cistern, the inner wall g of the cover being,` interposed between the previously -inentioned walls ot the cistern.
The cover does not actually rest on the tloor ont the cistern but is supported by legs 7i which may be attached in any convenient manner as indicated in Fig. l or may form a portion ot the casting` as shown in Fig. 2.
In like manner the internal portions o and (l do not extend to or come into contact with the portion e but leave a small clearance space corresponding` approximately with the space toi-med by the legs between the bottom ot the cover and the tloor of the cistern.
In any convenient position on the cover I mount a snitter pipe or valve y' which extends through the outer wall near to the top and communicate with the air space which is formed immediately below the cover plate e, its lower end protruding downwards to a position near to the bottoni ot the wall f.
In Figs. 2 and l I have shown a recess formed in the periphery of the outer wall for the accommodation of the snifter pipe indicated at j. This arrangement enables the pipe to be litted into a screw-threaded hole yat j? t-hus enabling it to easily be elevated or depressed for adjustment purposes.
From the top of the roof or cover I eX- tend an air pipe having an outlet Z at its lower end which may with advantage be titted with an india-rubber seating. This constitutes an outlet valve for the air which may be closed by any convenient means as for instance by the plate in which is supported on a hinge pin a and is pressed against the outlet of the air pipe by the spring o, the operation being efected by the press button p thus enabling the air to be discharged through the pipe from the underside of the cover thus causing syphonic action so that the water is easily discharged through the portions o `and c.
rlhe method of fitting this apparatus can be varied according to requirements7 and the water supply is of an ordinary nature consisting preferably of the inlet pipe q which is litted with an ordinary valve r against which the lever s of the floating ball presses as the water rises or releases when the water falls, but I provide an extension pipe t below the valve the bottom portion of which extends towards the floor of the cistern' thus reducing or eliminating the noise which would otherwise be caused by the inliowing water.
It will be understood that the cover does not rise and fall as is at present the custom with the majority of flushing cisterne now in use but may be regarded as a iixture but it is easily accessible for inspection or repair b v nisconnecting it from the air pipe c which leaves it freeto be lifted. This arrangement enables the whole of the water tanl. to easily be covered with a wire ganze covering a or other cover.
The situation of the 'water inlet is such that the water can rise above the topr plate of the cover, and consequentlyv presses upon the air which is imprisoned therein thus preventing the outflow by syphonic action, until the pressure is released by the outlet of air through the valve and pipe as previously described.
From the foregoing description it will readily be seen that the cistern is put into action by opening the air pipe f. lVlien the cistern is in action and the water is being discharged the snifter pipe allows the air to enter and thus stops the syphonic action before the outgoing water falls to the level of the bottom of the cover thereby minimizing the noise which would otherwise be caused by the complete emptying of the cistern. The general principle described in the foregoing paragraph is already wellknown.
Having now fully described and ascertained my said invention, and t-he mannerv in which it is to be performed, I declare that what I claim is l. In a sanitary flushing device of the character described, a cistern, a discharge pipe extending into said cistern, arconcentric upright wall surrounding said discharge pipe, a cover comprising a flat top piece and concentric depending walls adapted to nest about said pipe and upright wall, the outer of said depending walls having an axial depression extending almost to the tl'at top piece, and a snifter pipe in said depression, the outer end of which extends through the closed end of the depression to establish communication between the outside of the depending wall and the inside space directly beneath the cover piece.
2. In a sanitary flushing device of the character described, the combination of 'elements as set forth in claim I, the opening in the closed end of the depression being threaded, and the upper end of the snifter pipe being threaded to engage said open` ing to allow vertical adjustment of thesnifter pipe by rotation thereof.
In testimony whereof he hath atlixed his signature.
