SANITARY CHEMICAL-v-CLOSET.

Application led April 5, 1915.

To all lwhom t may concern:

Be it known that I, HARRY Y. SoARBoR- oUGH, citizen of the United States, resident of Minneapolis, county of Hennepin, State of Minnesotay have invented certain new and useful Improvements in Sanitary Chemical-Closets, of which the following is a specification.

The object of my invention is to provide a self-flushing closet or one having a waste outlet through which the contents of the closet will be discharged by siphonic action when a quantity of the refuse in solution has accumulated in the bowl.

A further object is to provide means for controlling ythe siphonic action of the closet and supplying a suitable sterilizing agent thereto, following the automatic discharge of the closet contents.

A further object is to provide a closet that will be absolutely sanitary and adapted particularly for rural districts and other places where there are no sewer connections.

A further object is to provide a closet of simple construction and one in which all the parts are readily accessible for examination or repairs.

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 specication,

Figure 1 is a vertical sectional view through a closet embodying my invention,

showing the parts in their normal position,l

Fig. 2 is a similar view, looking from the opposite side of the closet, showing the cover raised,

Serial No. 19,179.

the closet, made of suitable material, such as porcelain, and provided with a'v top plate 3 whereon the seat 4 and cover 5 are hinged. A flanged ring 6 is preferably placed on the top of the bowl under the seat. Within the bowl a wall 7 is provided, downwardly and inwardly inclined and havin an opening 8 therein. A late 9 is mounte on ay shaft 10 having bearings in the'wall of the bowl and operatively connected through a rod 11 with a crank12 on a shaft 13. This shaft has a connection 14 with the cover 5, the parts being. so arranged that when the cover is closed the plate 9 will be tilted down toward the bottom of the bowl and submerged in the solution therein, as shown in Fig. 1. When the cover is raised, the plate will be lifted through the opening to the position shown in Fig. 2. This construction is substantially the same as shown in my application Serial No.y 835,949, filed May 2, 1914, and detailed description and illustration of the same herein is not necessary.

Adjacent the bowl is a' chamber 14 having a pump device 15 connected by a rod 16 with the shaft 13, so that when the cover is raised the plunger of the pump will be lifted also and a quantity of the deodorizing fluid in the tank 14 will enter the pump and be forced up through the discharge pipe 17, which has an open end beneath and near the cover to spray the deodorizing fluid across the top of the bowl and over the wall 7 and the surface of the plate 9. This feature of the closet shown herein is also substantially illustrated in my application above referredto.

The upper portion of the bowl has a passage 18 communicating therewith and leading to a vent pipe 19. The lower portion of the bowl has an opening 20 communicating at one end with a siphonic duct or passage 21l that is formed in the rear wall of the bowl and within the chamber 14 and has a discharge opening 22that is normally sealed by a: valve 23, said discharge opening communicating with a waste pipe 24. The valve 23 has an operating rod 25 which extends up through vthe top ofthe. bowl and the upper wall of the chamber 14C into the passage 18 and has its upper end loosely mounted in the lower portion of a handle 26 which serves as a continuation of said rod and extends vertically across the passage 18 through a. hole in the top plate 3, where it can be conveniently reached. When the top of the closet is removed, this handle is detached from the valve rod. Secured to the upper end of the rod 25 by suitable means, such as a set screw 27, is a collar 27.

A compression spring 2S is preferably interposed between the collar 27 and a packing 29, which encircles the rod 25 and forms an air-tight joint at the point Where said rod passes through the wall of the siphon.

i The spring 28 is put under tension when the handle 26 is depressed to open the valve, and when the handle isreleased the spring will raise the valve automatically and seat it to close the discharge opening of the siphonic duct.

At the rear of the closet I prefer to provide a receptacle 30 adapted to contain a chemical sterilizing agent in liquid form. A tube 31 is mounted in the bottom of this receptacle and projects upwardly therein and is closed at its upper end and provided with a port 32 near the bottom of the receptacle. The lower end of the tube is open and provided with a by-pass 33 having a port 311 through the wall of the tube. Below the discharge end of the by-pass a depression 35 is formed in the wall of the bowl, leading to the wall 7 and adapted to conduct the sterilizing and germicidal fluid to the contents of the bowl.

Within the tube 31 is a plunger 36 having a pin 37 passing through a slot 38 in the wall of the tube and mounted in the handle 26 so that when the handle is moved vertically, a corresponding movement will be imparted to the plunger. The plunger is hollow and provided with a port 39 at its upper end and a port 40 at its lower end. Normally, when the handle and plunger are raised, the port 39 will be out of register with the port 32 and the port 4:0 will be in register with the port 34C, but when the handle is depressed to open the waste pipe valve, the plunger will be moved downward also until its port 39 registers withl the port 32, whereupon a supply of chemical solution will flow from the receptacle 30 and when the handle 26 is released, and the spring 28 returns it to its normal position to close the vwaste valve, the plunger will be raised, cutting off the entrance of the solution to the plunger and causing the ports 311 and 40 to register, whereupon the liquid in the plunger will flow out into the depression or valley and be delivered to the contents of the bowl. The formation of 'a vacuum in the top of the tube 31 is prevented by a suitable vent 41. The chemical sterilizing agent delivered to the bowl each time the waste valve is operated will be sufficient to render the accumulation in the bowl absolutely sterile and each time the cover is operated this accumulation will be agi-` tated and the solids broken up by the action of the swinging plate or member 9.

The closet is designed for use without dumping` until such time as the contents accumulate or rise above the entrance to the y siphon, as illustrated in Fig. 1, and at such released and discharged into the bowl, thev volume being suliicient to completely sterilize the accumulation therein and maintain this sterile condition until the bowl is again filled to a suitable discharging point. The closing of the cover will tilt the agitating member-9 down into the solution and thoroughly agitate and break up the contents of the bowl and at the same time the pump device will be operated to thoroughly spray and deodorize the upper yportion of the bowl and the surface of the wall 7 and the tilting member.

In various ways the details of construction hereinshown and described may be modified and still be within the scope of my invention.

I claim as my invention:

1. A closet comprising a bowl having a discharge opening, a receptacle adapted to contain a chemical solution, a tube having a port below the level of said solution, the lower end of said tube having a discharge port and a passage communicating therewith, a plunger provided within said tube and slidable therein and having a port-to register with said inlet port when said plunger is in a predetermined position and also having a port to register with said outlet port at a predetermined point, whereby with each movement of said plunger a supply of the chemical solution will be received and discharged, and means arranged to receive the chemical solution and deliver it to said bowl.

2. A closet comprising a bowl having a discharge opening, a receptacle adapted to contain a chemical solution, a tube depending therefrom and having a port below the level of `the SOlutiOn, the vlower .end of said tube having a discharge port and a passage communicating therewith, a hollow plunger provided within said tube and vertically slidable therein and having a port to register with said inlet port when said plunger is depressed, and also having a port to register with said outlet port when said plunger is raised to a predetermined point, whereby, with each movement of said plunger a sup- 10 ply of the chemical solution will be received and discharged thereby, and a wall arranged to 'receive said chemical solution and deliver it to said bowl.

In witness whereof, I have hereunto set my hand this 25th day of March, 1915.
