Patented Mar. 16, 1937 UNITED STATES PATENT cries 12 Claims.

This invention relates to toilets, and particularly to toilets of the character used in summer cottages, farmsgcabins', camp trailers, boats, or in fact any place where the conventional type of plumbing has not been installed. Many types of so-called chemical toilets have been on the market'for a number of years using a container into which isplaced a quantity of water, and the water is intermixed with some chemical which is supposed to dissolve the refuse, or a deodorant is placed therein which is supposed to overcome the odors emanating from the refuse. Toilets of this type, in addition to being unsanitary, are not odorless, especially during the summer season when a cottage or camp trailer is subject to high temperatures. In addition to the above, some of the chemicals and deodorants sold are very nauseating to many people. It is the primary purpose of the invention herein described to provide a new and improved sanitary toilet which is selfcontained, and at the same time providing a toilet approaching the advantages of the modern toilet installed in a location providing running water and modern sewage disposal.

Another object of the present invention is to provide a new and improved toilet comprising a container into which is nested a new and. im-

proved bowl and valve assembly so constructed that odors cannot escape from the container below the bowl and valve assembly into the surrounding atmosphere.

More specifically the object is to provide a bowl assembly having a bowl of such shape that it converges toward an opening which has an edge at the lowermost point in said bowl, said opening being inclinedupwardly in a direction substantially parallel with one side of said bowl. Such a bowl enables the use of a valve closure which, while effective for emptying the bowl, is not subject to collection of sediment such as would be the case with a valve at the bottom of the bowl. It is also possible with such construction to cover the opening-and valve with water thereby effectively sealing the same against escape of odors.

A still further object of the present invention is to provide a new and improved valve and valve operating mechanism for discharging refuse from a bowl assembly into a refuse container below the same.

Another object of the invention is to provide a new and improved flushing means whereby a deposit of fresh water may be allowed to enter the bowl portion of the toilet when desired by the operator. g

A further object is to provide new and improved means for locking the bowl assembly to the container.

A. still further object is to provide a new and improved toilet that is at all times odorless. and which does not require the use of chemicals or deodorants at any time. i

The above and other objects of the invention will appear more fully from the following more detailed description; and from the drawing Where- Fig. l is a top plan view of my invention; Fig. 2 is a section taken substantially on the line 2-2 of Fig. 1; and

Fig. 3 is a portion of a section taken substantially on the line 3-3 of Fig. 1, and showing the top bowl portion clamped to the container portion in accordance with the principles of my invention.

Referring now to the drawing, the numeral l0 designates a container or other sewage receiver of any suitable size or shape, but as shown best in Fig. 2 of the drawing, is cylindrical in shape. The top of the container [0 is bent to form a circumferential flange or ledge ll,'the stock being rolled to formv a bead l2, for a purpose later to be described. The bowl I3 is formed in one piece, as shown best in Fig.2, to define a sump orcontainer, the upper portion thereof being bent to form a wide circumferential flange l4, thestock being bent'around .to form a narrow circumferentia1 flange l5 adapted to be aligned with and rest upon flange ll of container ISL. Interposed between flanges II and I5 is disposed a gasket 5 to form a seal between thetcontainer. Ill and bowl l3 so that neither liquids nor gases may escape from the container II].

There is provided an annular discharge orifice or opening ll in the bowl l3, and to open and close this opening when desired there is provided a valve comprising an arc-shaped rubber member l8 secured to a metal disc l9 by means of a bolt and nut 20. The metal disc it ishinged upon the pin 21 which passes through a pair of lugs 22 formed on the side of the bowl [3. A spring 23 to hold the valve [8 normally in a closed position, as shown best in Fig. 2, is bent around the pin 2| between the lugs 22, the'lower portion of the spring contacting the back of metal disc l9 upon which valve I8 is secured.

It is to be noted that the opening H has its lower edge at the lowermost point in the bowl and that the opening is inclined and extends upwardly in a direction substantially parallel with the side of the bowl.

To manually .actuate'valve l8 there is provided said projection into the container I9.

a lever 24 secured to the handle 25 by means of the pin 26. The lever 24 is journaled in sleeve 26, said sleeve being secured to the outside of the bowl of the toilet in any conventional manner, such as by soldering or riveting, and passes from the exterior to the interior of the toilet, as shown in Figs. 1 and 2. Lever 24 is bowed, within the container, to conform to the shape of bowl l3, and terminates in a cam portion 28. This cam 24 is adapted to engage pulley 29 which is secured to pin 30, the pin passing through lug 3| formed on metal disc I9. When lever 25 is moved to the left, as shown in Fig. 2, lever 24, together with cam 28, is moved to the dotted line position of Fig. 2, cam 28 rolling through pulley 29 and, as pulley 29 is secured to the back of metaldisc l9, valve I8 is raised from its seat allowing the contents of bowl l3 to be deposited into container I].

So that the user will know definitely the height of the liquid in container I0, there is provided a projection 32 having an opening 35 from A float 33 is disposed within this tube-like projection and there is secured to the float 33 a measuring rod 34 which passes through an opening in the projection cap so that it may move vertically up or down according to the depth of the liquid in the projection 32. This measuring rod is properly marked to show quarter full, half-full and full so that the user will know exactly when the container I0 should be emptied.

A conventional toilet seat 31 having a cover 38 hinged thereto by means of hinge 39, is secured and rests upon flange I4 by means of bolt and nut 40. The seat 31 protrudes slightly inward, as shown in Fig. 2, to form an overhang beyond the flange l4, so that all refuse will fall directly into the water in bowl I3 and not strike the sides of bowl l3.

To refill the bowl l3 with water after valve l8 has been actuated, there is provided a supply tank 4|, the same to be secured to the wall above the toilet at any convenient height to provide a gravity feed therefor. This tank is supplied with a tight fitting top to prevent loss of water when the toilet is installed in a camp trailer, or other moving vehicle. A conventional release valve 42 is installed directly below the tank, the same being actuated by means of the lever 43 which has chain 44 secured thereto, said chain being of suflicient length to facilitate the user grasping handle 45 when it is desired to operate valve 42. A flushing pipe 46, having a plurality of staggered apertures 41 therein, is disposed within the upper portion of bowl I3 and is held in place by means of coupling nut 52. Pipe 46 lies directly below and under the overhang of seat 31, the same passing entirely around the inner circumference of bowl I3 and passes out through the side wall of the bowl assembly where it is held in place by means of coupling nut 48. The end of pipe 46 is open, a cork 49 being inserted therein as a plug which may be removed when it is desired to clean the pipe of foreign matter which has collected therein during use. Flexible tubing 59 is used to connect tank 4| with pipe 46, said tubing being secured to the outlet pipe of valve 42 and inlet end of pipe 46 by means of strap 5|. Strap 5| enables the user to disconnect flexible tubing 50 from pipe 48 when it is necessary to free the container ID from the water supply tank 4|.

Clamping means 53 are provided to secure the bowl |3 to the container l0, said means comprising, as shown best in Fig. 3, a clip 54 secured to the bowl by means of a rivet 55. The clip 54 is hinged on pin 56 and hooked member 51 is hinged within the member 54. As shown best in Fig. 3, the hooked member 51 is shown engaged upon the bead 2 to secure the bowl and container sections of the device in locked engagement. To release securing means 53 the clip 54 is moved to the right to the dotted line position of Fig. 3, this allowing the hooked member 51, which is pivoted on pin 58, to free itself from bead H.

A bail 59 is secured to the container H] by any suitable means such as the ears 6!] which are aligned on opposite sides of the container, as shown best in Fig. 1. The bail 59 enables the user to conveniently carry the device when it is necessary to empty the container.

There is provided an opening in the lower portion of the container ID to which is secured a threaded projection 6|. A threaded cap 62 is adapted to engage the threaded projection 6| and close the opening into the container.

The manner in which the device operates is as follows:

The water supply tank 4| is first filled to capacity and the cover placed thereupon. To transfer a quantity of water from the supply tank 4| to the bowl I 3, the user acuates valve 42 by pulling upon handle 45 which in turn operates lever 43. The water flows by gravity down conduit 50 into flushing pipe 46 where it is released through the plurality of staggered apertures 41 into bowl I3. When the desired quantity of water has been released, the handle 45 is released and valve 42 then closes automatically. As valve I8 is in a closed position, as shown in Fig. 2, the water remains in the bowl I 3 and the toilet is ready for use. When it is desired to dump the contents of bowl l3, the user operates lever 24, by means of handle 25, moving the same from right to left as illustrated in Fig. 2. Lever 24 being journaled in sleeve 21 and terminating in a cam 28, which in turn passes through pulley 29 which is secured to the back of valve l8, valve I8 is swung to an open position against spring 23 to the dotted line position shown in Fig. 2. The water in bowl l3 then passes out through opening H and dumps into container I0. When handle 25 is released by the user, valve I8 is returned to its normal position, as shown in Fig. 2, by means of spring 23. Inasmuch as valve I8 is of rubber and the circumference of opening I! is rounded, the arc-shaped rubber face of the valve forms a liquid tight seal. When valve l8 has again been closed, the operator then releases valve 42 by means of chain pull 45 and another quantity of water is deposited in bowl l3. It will be noted from Fig. 2 that bowl |3 is so shaped that all refuse will drop directly into the water in the bowl and will not strike the unprotected sides of the bowl. Inasmuch as the water enters the bowl I 3 through apertured pipe 46, and as the holes in pipe 46 are staggered the water is directed toward the interior of the bowl in a plurality of directions thus effectively clearing the bowl with a minimum amount of water, a result of utmost importance in a unit to be used where only a limited quantity of water is available. When it is desired to clean flushing pipe 45 of any sediment that might lodge therein, and therefore plug apertures 41, the user simply removes the cork plug 49, Fig. 1, which closes the open end of flushing pipe 46, and any foreign matter lodged in the pipe will be carried away through this opening.

garners E T When the gauge: sticknfl. discloses that. the container-l0 shouldv be emptiedpthe userxiisengagesiconduit 50 from. flushing-pipe- 46, by loosening strap .5 l Bail 59 .may then be swung to ;a position above the device so that the con.- tainer may betransported. If two people wish to carry the container, the: same could be pro!- vided with a'handlepn .each side thereof similar to thehandlesjcommonly seenonla'rge ash containers. During the period whenth'e device is being transportedatoithe locality where the refuse is to be buried, the valve 18 remains closed and no odors may escape from the container Ill. To empty the container, the clamping means 53 are opened by moving the clip 54 to the right, as shown in Fig. 3, so that the hooked member 51 is freed from the bead I2 of the container Ill. The entire bowl assembly is then removed from the lower container I0 and the contents dumped. If the user does not wish to carry the entire device to the dumping locality, the bowl assembly may be removed and a top cover which fits neatly over the bead l2 of container l0, may be installed to prevent spilling and splashing of the contents of the container during the carrying period. Container l0 may also be emptied by removing cap 62 from projection 6] and tilting the container sufiiciently to allow the contents to flow out the opening in the container.

Should it be desired to install my device in a location where there is already in use a toilet using a tank or other means of sewage disposal, the container l0 may be constructed as an openended cylinder which may be fastened to the floor directly over the opening leading to the tank below. This would do away with the necessity of dumping the container and also do away with the disagreeable odors so prevalent with toilets of the tank type, the valve l8 being a complete seal against any escape of gases from below ground.

I have described a new and. improved toilet that will be cheap to manufacture and assemble, and yet it will provide the user with the same high efficiency of operation that one expects from the new and improved toilets installed in the newer buildings throughout the country. It pro-- vides an ideal odorless toilet for camp trailers where the problem of refuse disposal has been one of real concern, inasmuch as a trailer is on the road during the heat of summer and if a chemical is used, there is always some odor, even if it is that of the so-called deodorant itself. The water supply tank is fully enclosed so that there is no chance of spilling the contents while enroute.

While I have shown and described a satisfactory constructional example embodying the principles of the present invention, it will be understood that many changes, variations and modifications may be resorted to without departing from such principles.
