England l Application January 10, 1938, Serial No. 184,286 r v i, In Great Britain January 9, 1937 n X r 7 Claims. (Cl. 4-115) This invention relates to sanitary closets using chemical liquid as a solvent and deodorizer and of" the kind. in which a tank houses areceiving tray adapted to be raised from the liquid for use and generally provided with a hinged seat cover, in which casethe seat coveris coupled with the mechanism for raising and lowering the tray 6 receiving tray carried by a plurality of axially movable bars extending up through the top of the tank; a cross member interconnecting said 20* bars externally of the tank and movable as one with the bars and tray; a lever'coupled to the cross member having a member cooperating with a track or guide; means being provided for retaining said member in engagement with the 25* track or guide and friction means which may be either'the same as the retaining means or separate therefrom for restraining its, movement therealong; f

In order that itImay' be clearlyunderstood 30 and more readily carried into efiect, the inven' tion is hereinafter described with reference to the accompanying diagrammatic drawings, in which: Figure 1 is a side-elevationnof a sanitary closet 315* according to the invention with the lid closed and the tank broken away to reveal the interior;

Figure-2 is a plan View corresponding to Figure 1; a

Figure 3 is a side elevation similar to Figurel '0 but showing the lid open; while t Figure 4 is a detail View of a drain plug with a shut-off device for use where the closet is used inside without an outlet to an earth pit.

Referring now to Figures 1 to 3 of the accom- 4'5 panying drawings, the tank 5 is intended to be filled with liquid approximately to the level indicated by the reference 6. The forwardpart ofthe top of the tank is openand is provided with a sanitaryseat cover I, over which there is 56 hinged a lid 8 adapted to be opened and closed over the aperture in the seat I, as required. Belowthe seat 1 and within the tank 5 is a receiving tray 9 of trough-like form, generally being of greater depth at the rear than at the front.

5;"I'he bottom of the tray is preferably of semicirreturned thereinto after use. Such a closet is (Granted under the provisions of sec. 14, act 01' i March 2, 1927; 357 O. G. 5)

cular section and is open at theback. The tray is carried on arms N which extend up'rearwardly asfa pair of bars passing out throughholes' in the top of the'tank through the guides I2 forcooperation with thef'cross member 13; The 5" bars ill can slide vertically in the guides l2; and consequently the cross member I3,'the verticalbars i I and the arms Ill provide a framework carrying the trough 9 which can move vertically so that the tray may be caused either to be lifted out of the liquid, or at least the base thereof immersed. Pivotally connected to the cross member I3 bymeans of a sliding collar M rotatable on the cross member is a lever 15, which is coupled to the lid e by the eye-bracket It, 15 whereby the lid may be raised or lowered by the lever [5; The eye-bracket 86 has the transverse rollers Hand l8 engagingrespectively, above and below the lever 55 to provide for free movement of the lever in the eye-bracket. The lever i extends rearwardly from the sliding collar l4,

as indicated at l9, the downwardly-directed end of the extension being forked to receive a roller 20. The roller is adapted to move along a guide track whenthe lever 15 is operated to raise or lower the lid. The track is comprised by the upper part 2| and a lower spring member 22. The upper part 2| is of course spaced above the lower spring part 22, and the efiect of the spring '22 is to grip the roller in order to preventit running back too freely when the lever is moved downwards to lower the lid and cause the receiving tray 9 to re-enter the liquid. The upper part of thetrack conveniently will extend down as the vertical arm 23 adapted to be at-: 5" tached to the back of the tank, while theother end thereof can be turned'down, as indicated at 24; te meet the front end of the spring member 22 sothat the two parts of the track c'anbe bolted together on the topof the tank. l 1 I "In Figure 3 the spring member 22 of the track is'shown in the position which it assumes when the rjoller is at the front" end of the track, as it isfwith the seat inthe raised condition. A closet as hereinbefore described may be madefup a simple and light formso that it can be, carried away for emptying, or maybe for transportation,;, and to facilitate lifting it the s handles 25 may be provided. i 5 c; Preferably, such a closet as above described 0 will be installed over an earth pit, and will have a drain plug includinganoverflow device associated with it. The drain plug will preferablyen gage in a boss of rubber, specially treated to ref 5 sist the action of the caustic materials of the liquid usually employed in chemical closets.

Where the closet is intended to be used without an earth pit, for example in a caravan or perhaps in aboat, the drain plug will preferably include means for shutting off the overflow, and a plug with such shut-01f means is illustrated in Figure 4. The plug itself, indicated by the reference numeral 26,, has a central aperture through it and has upstanding from it the outer tube 2'! with an aperture 28., .Within the tube 21' is an inner tube 29 having an aperture 30,.

which when ordinarily operating to provide an overflow will be in register with the aperture 28. flow, as it may be when the device is used without an earth pit, the inner tube 29 may be turnedby means of the knob 3i until the aperture 3% no longer registers with the aperture 28. The plug 26 will when properly engaged in the outlet be held sufliciently tightly to enable the inner tube 29 to be turned without turning the'plu'g. In order to define the limits of angular movement, and to position the aperture 3i] properly with respect to the aperture 28, a grub screw 32 will be engaged in the inner tube 29, the outer tube 21 being slotted, as indicated at 33, to permit movement of the grub screw. The guard-tube 34 with its apertures, such as 35, is provided to prevent undissolved paper or solid matter from fouling the overflow. In order to provide access to the handle SI for shutting off the overflow, and

also for removing the drain plug as a whole, there I will be an aperture in the top of the tank, for which the cover SB'will be provided.

The lid 8, although not absolutely necessary, is

obviously desirable, but where it is dispensed with the tray may be caused to rise and fall by means of a lever corresponding to the lever lfi, which maybe considerably shorter than where it has to engage the lid, the rest of the structure rewithout an earthpit, as it would be in a caravan maining substantially the same with the excep-g tion of the means for coupling the handle l to the lid.

Again, in cases where the closet is. to be used or in a boat, the tank 5 may be lined with a separate container intended to belifted out for emptying, but in such a case it would not be'desirable ,to include an overflow and the inner container will need to be emptied out from time to time before it gets too full.

It will be apparent that numerous arrangements may be provided for introducing the necessary friction between the roller and its guides; for

" example, the roller may be connected to the seat or a convenient fixed anchorage on the tank by means of a spring, so placed as to tend to draw the lever inner end into engagement with the guide during downward swinging movement of said lever. Similarly, a friction member may be included in the hub of the roller, which then need not be gripped by spaced guide members but merely located by them.

forwardly over that member but'spaced therefrom so that the'roller is pressed into-frictional contact with the track to be gripped between the projection and the track at least towards the rear end or the track. w
