Application filed May 2, 1914. Serial No. 835,949.

To all whom it may concern:

Be it known that l, HARRY Y. SonnnonoUoi-r, citizen of the United States, resident of Minneapolis, county of Hennepin, State of Minnesota, have invented certain new and useful Improvementsin Sanitary Closets, of which the following is a specilication.

The object of my invention is to provide a closet of simple construction and composed of parts which are readily accessible for cleansing purposes or for repairs.

A further object is to provide improved means for concealing at all times the excrement in the closet.

A further object is to provide improved means for agitating the chemical solution in the closet, thereby insuring breaking up of the excrement and the thorough sterilization of the same.

A further object is to provide improved means for thoroughly spraying the closet.

Other objects of the invention will appear from the following detailed description.

The invention consists generally in various constructions and combinations, all as hereinafter described and particularly pointed out in the claims.

In the accompanying drawings forming part of this specification,

Figure l is a vertical sectional view through a sanitary closet embodying my invention, the parts being in their normal operating position,

Fig. 2 is a similar view, in which the platelike member normally supported above the chemical solution is shown tilted to a point within the solution by the closing of the cover,

Fig. 3 is a vertical sectional view, looking toward the front of the closet,

Fig. 4 is a plan view,

Fig. 5 is a vertical sectional view through the closet from the front to the rear thereof, showing a modified construction,

Fig. 6 is a vertical sectional view taken on a section line at right angles substantially to the section line of Fig. 5,

Figs. 7 and 8 are detailed sectional views, showing the lifting handles and the means for locking the discharge valve in its closed position.

In the drawings, 2 represents a suitable tank, made preferably of sheet metal and adapted to contain a sterilizing and deodorizing chemical solution. The tank is preferably provided with an extension 3 at the rear thereof, having in its upper walls a ventilating pipe l. A plate 5 is mounted on the top of the tank over the rear portion thereof and to this plate is hinged a seat portion 6 and a cover 7, the seat portion norn'ially resting upon the top of the tank. A shoulder 8 is formed on the walls of the tank near the top thereof and a plate 9 is fitted within the open top of said tank and has a downwardly turned flange 10 to rest upon the shoulder 8. The plate 9 is inwardly and downwardly turned, projecting from the "wall of the tank beneath the opening in the seat 6, and is provided at the front with a recess 11 formed by bending the forward portion of the plate upwardly, as indicated in Fig. 3. A guard wall 12 depends in front of this recess.

l/Vithin the tank I arrange a hopper-like receptacle 18 fitting snugly against the wall of the tank on the front and sides thereof and having an open top beneath the seat opening in which a tapered ring lt is fitted and secured, forming an inwardly inclined wall beneath the seat opening. The bottom of the receptacle 13 is hopper-shaped, converging toward the discharge opening 15 leading to a waste pipe 16. A valve 17 is seated in the discharge opening 15 having a yielding packing ring 18 to fit snugly upon the wall of the receptacle and form a close, liquidtight joint therewith, and lifting rods 19 are attached to said valve and extend upwardly therefrom, preferably through trans verse slots 20 in the ring 14. On the upper ends of the lifting rods 19 handles 21 are pivoted and provided with eccentricallv mounted pins 22 which are adapted to enter recesses 23 provided in studs 2 1 mounted on the side walls of the tank adjacent to the lifting rods. When the handles 21 are swung to the position indicated in Fig. 7, the pins 22 will be disengaged from the studs 2 and the rods and the valve may be lifted out of the closet. \Vhen, however, the handles are swung to the position indicated in Fig. 8, and the pivotal connections of the handles swung to a point beneath the bearing surfaces of the studs, the handles and lifting rods will serve as toggle connections to force the valve 15 downwardly upon its seat with sufficient pressure to close the discharge opening. A shaft 25 is mounted in bearings in the lifting rods and provided with arms 26 on which a plate-like member 27 is mounted, having, preferably ,an upper. surface that is slightly convex. This member 27 is adapted to swing up into the ring, 14,

and partially close the opening theretl rouglrand conceal the contents of the. receptacle beneath. A plate 28 is preferably mounted on the lifting arms and has an upper edgefitted to bear on the wall of the ring 14 and a slotted opening 29 to receive the arms 26 when the member 27 is swung to its raised, normalposition. This plate 28 cooperates with the member. 27 to completely concealfthe chemical solution receptacle and the contents thereof when the cover is raised, and breakup the swash of the contents of the receptacle whenused in a moving vehicle. Suitable counter-weights 30 normally hold, the member 28 in itsraised position. A shaft 31- is mounted" in suitable hearings in the wallsof the tank near the top thereof and isvprovidedwith a crank arm 32 pivotally connectedby suitable means, such as a rod 33, with an arm 34 onthe shaft 25. When, therefore, the shaft 31 is rocked, a corresponding movement will be imparted to the shaft 25 to swing the member 27 from the position shown in Fig. 1- to that shown in Fig. 2, or to lift the member to its normal position within the ring 14.

The member 27' may. also be utilized in case an examination of the excrement is desired before discharging it into the chemical solution. To insure the positive movement of-the, member 27 I prefer to connect it with somepart of'th'e closet, such as the cover 7, which must be raised to expose the seat opening or closed to cover this opening. The connection consists preferably of an arm on the shaft 31-, connected by a link 36 to a curved bar 37 that is mounted at one endon the cover 7' near the, hinge thereof, andis slidable through an opening 38 in the plate 5, Through this connection/the, member 27-ispositively raised to its normal position beneath the seat opening when the cover is raised, and positively swung down to its submergedposition in the chemical solution when the cover is closed. A stop 39 is preferably provided-to engage theplate 5 and arrest downward movement of; the curved bar 37 and the opening movement of the cover 7 thereby preventing damageto any of the connections.

For the purpose of spraying the exposed portions of'thecloset I prefer to mount a sprayer 40 having a nozzle to overhang the ring 14 and con'iniunicating with a pump barrel4l which depends withinthe tank2 and the solution therein and is provided with intake openings 42. A pump plunger 43 is mounted to slide in the barrel. 41, and has astem ,44 projecting through the top of thebarrel and-provided with a toothedupper portion 45 adapted to mesh with teeth 46 on. the curved bar 37, whereby when the cover. 7is opened or closed the pump plunger will be reciprocated, and the parts are soadjnsted that when the cover is raised the plunger will be depressed, allowing the solution in,the barrel to flow upwardly through the usual check valve in the plunger, not shown, to the space above the plunger, and when the cover is closed, the plunger will be moved upwardly and the accumulation of chemical solution between the plunger and the top of the barrel will be forced out through the spraying, device, upon the exposed surface of the closet, thereby thoroughly cleansing and deodorizing the same.

The upper portion of the plungerrod is arranged to slide preferably in a tube 47 on which a guard 48 may be formedto project between the cover 7 and the tube 47. During the sprayingoperation, the member 27 will be swungto its inverted position and gradually submergedin the solution in the receptacle, being thereby cleansed of any excrement which may be adheringthereto and also serving toagitate the contents of the receptacle andseparate the excrement therein and cause a thorough disintegration andsterilization of the same.

In Figs. 5 and 6, I have shown a modified construction, which consists in substituting a member 49 substantially oval in form having a shaft 50 -111Qll11i'6tl in the lifting rods, one ofsaidshafts having a pinion 51 thereon to engage a tooth'edrod 52 that is pivotallyconnectedwith the arm 32. This member 49projects upwardlyinto the opening inthe bottom of the ring 14- and depends also within the chemical; solution in the receptacle 13, and'having the functions ofthe member 27 to conceal-the contents of the receptacle. Beneath this member 4-!) ll preferably provide a curved plate 53 sup ported by the lifting rods and;adapted-to contain a quantity of chemical solution throughwhich the member 49-passes as it is revolved on its bearings, and said plate 53-has preferablyan edge 54 which normally contacts with the member 49 to thoroughly clean the surface of the same. The i V movement of-' this member 49 is preferably effected through connections with. thecover of 'the closet corresponding substantially to that already described in detail.

lVhenever desired, the cover 7 may be raised 'and the plate 9 removed, exposing the lifting handles and upon disengaging the pins 22 from the studs 24 andthe rod 33 from the arm 32, the rods maybe raised, carrying with them the-plate 28, the member 27and the valve 17, exposing thereby the discharge opening and allowing the contents of the receptacle to pass out through; the waste pipe 16; Further upward movement will lift the parts connected-to the lifting rods entirely out of the closet, when access may be had to the different parts and to the interior of the closet.

In practice, the various metallic parts of the closet, such as the plates, the ring 14, the solution receptacle and the tilting members, are surfaced with enamel, thereby permitting the convenient cleansing of the same and preventing injurious chemical action.

The closet may be made in various sizes and in various ways and the details of construction herein shown and described may be modified and still be within the scope of my invention.
