Application le. August 11, 1913.

To all whom t may concern:

Be it known that we, HARRY Y. SoAnouonen and JAMES G. KING, citizens of the United States, residents, respectively, of Minneapolis, county of Hennepin, State of Minnesota, and Superior, county of Douglas, State of llisconsin, have invented certain new and useful lmprovenients in Sanitary Closets, of which the following is a specification.

The object of our invention is to provide a closet adapted for use in residences, schools, hospitals, railway stations and other places having no sewer connections, and particularly applicable for railway coaches and other vehicles.

A further object is to provide a closet of sanitary construction and one which willbe odorless under all conditions, and in which all germ life found in human eXcreta and urine will be destroyed and all danger of infection therefrom eliminated.

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

ln the accompanying drawings forming part of this specification, Figure 1 is a vertical sectional view of a closet embodying our invention, Fig. 2 is a horizontal sectional view on the line of Fig. 1, Fig. 3 is a detail sectional view, showing the device for forcing the sterilizing and deodorizing chemical into the closet, Fig. l is a detail sectional view, illustrating a modified construction, Fig. 5 is a detail sectional view, illustrating a modied means for delivering the chemical to the closet receptacle.

ln the drawing, 2 represents an outer casing of suitable material, preferably wood, provided with an extension 3 at the rear having a top 4c whereon the seat cover 5 lis hinged. A discharge pipe 6 isprovided in the bottoni of the casing 2, having a flanged upper end and a seat 7 for a valve, preferably in the form of a convex disk 8, which is adapted to drop down upon the seat and the pipe G within the flange thereon and forni a tight joint with the pipe, preventing the discharge of the contents of the closet until the disk 8 is aised. liadiating upwardly and outwardly from the pipe 6 is a wall 9, substantially funnel-shaped and operating to direct the contents of the closet Specification of Letters Patent.

lower portions having threaded ends which are mounted in the disk 8 and pass through a similar convex 'disk 13 arranged above the disk 8 and spaced therefrom and concentric therewith. An upright rod 14 is mounted on the disk 8 and projects upwardly through the disk 13 and is provided with a preferably convex disk or cap 15. These disks are made of any suitable shape and are preferably made of porcelain, or of metal coated with porcelain, and are located directly beneath the seat opening, and when the desired quantity of chemical solution is discharged into the receptacle or the space inclosed by the tank 10, the lower disk may be partially or wholly submerged. At the top of the tank 10 is an inwardly inclined wall or flange 1G, also beneath the seat opening and provided with transverse slots 17 in which the rods 11 are vertically slidable, the central opening in the wall 17 being of suflicient diameter to allow the disks to be raised entirely out of the closet, the offset portions of the rods 11 sliding through the slots 17 during the vertical movement of the rods in the Voperation of removing the disks. The upper ends of the rods 11 are preferably threaded and provided with thumb nuts 18 having grooves 19 therein to receive clips 20 which are secured to the top of the tank 10. When these thumb nuts are screwed upwardly on the rods the lower disk 8 will be forced down iiri'nly upon its seat and the discharge opening herinetically sealed.

rfhe disk 15 and the flange 1G cooperate to conceal the contents of the receptacle and prevent it from swashing about and over the side walls of the tank when the closet is used in a railway coach or other vehicle, and the disk has the further function of breakthe closet.

In the upper portion of the tank 10 we provide a Ventilating pipe 2l communicating with a chimney or other ventilating stack, not shown. For delivering a suitable quantity of the chemical solution into the receptacle of the closet, we provide a pump 22 extending down through the Ventilating pipe 21to a point preferably near the bottom of the tank and having a plunger 23 and an operating rod 24. A hub 25 is provided at the upper end of the pump cylinder on which is mounted a hand wheel 26 by means ,of which a limited rotary movement may be imparted to the pump cylinder. The rod 24 extends up through this hub and a suitable packing 27 is provided with a hand grip 28 by means of which the pump rod and plunger may be operated. A pipe 29 has one end mounted in the cylinder of the pump and extends horizontally therefrom, inwardly under the cover 5 and has a downwardly turned inner portion 30 which projects through a slot 3l in the wall 16 and is provided at its lower end with a sprayer 32. This sprayer normally stands in the position indicated by full lines in Fig. l, at one side of the center of the convex disk 15, and whenever it is desired to spray this disk the pump cylinder is rotated, swinging the depending end portion 30 of the pipe 29 inwardly to a point where the sprayer is concentric substantially with the disks beneath. The pump plunger is then operated and a suitable quantity of chemical solution is pumped into the receptacle and the contents thereof are instantly sterilized and deodorized. The chemical solution falling upon the upper disk will wash away any excreta that may have adhered thereto, and will thoroughly ldisinfect the surface of the disk and destroy all germ life in the closet receptacle. 4The solution will also throw olf a gas from the disk surface which will neutralize any gas which may arise from the contents of the closet and prevent corrosion of the vent pipes and other metallic parts of the closet. l/Ve prefer also to provide air intake openings 33 in thc lower walls of the casing leading to the air chamber 34 between the casing and the solution tank, the 'connection with the stack establishing a circulation of air through the openings 33 around the receptacle of the closet and under the seat porhand wheel 40 for rotating it from an open f to a closed position or vice versa, and connected with a pipe 29 to move it and the sprayer back and forth in the slot 3l toward and from a position above the axis of the convex disks. to an" open position, the chemical solution will flow down by gravity to the sprayer and be discharged thereby upon the disks beneath, cleansing and thoroughly deodorizing and sterilizing them and the contents of the receptacle. As soon as the desired quantity of solution has been delivered, the valve will be returned to its closed position by the spring 41, shutting olf the flow of the solution from the tank.

lV e prefer to provide a guard or shield 42 beneath the forward portion of the cover 5, supported by suitable means, such as clips 43, and arranged to cover the air space 3l and the reservoir, and inclined inwardly and downwardly to direct material falling` thereon toward the receptacle of the closet. This guard is readily removable whenever it is desired to have access to the means for raising and lowering the valve disk.
