CLOSURE F013 SEWAGE-DISPOSAL SYSTEMS.

Specification of Letters Patent.

Patented Jan.28,19i3.

Application filed. March 25, 1912. Serial N 0. 686,097.

To all whom it may concern.-

Be it known thatv I, CoRNEALiUs W. RUS- SELL, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new. and useful Closure for Sewage-Disposal Systems, of which the following is a specification.

The present invention relates to improvements in closures for sewage disposal systems, the primary object'of the invention being the provision of a novel form of cabinet or closet used in connection with an air tight sewage disposal cell, whereby the weight of the occupant automatically opens a pair ofgates or doors for the reception of the excrement within the cell, the same automatically closing when the seat is released.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

In the drawings-Figure 1 is a perspective view of one of the cabinets. Fig. 2 is a vertical transverse sectional view through the cabinet,-the gates being in normal position closed, dotted lines illustrating the position of the location of the cabinet and seat when the seat is occupied. Fig. 3 is a. longitudinal section through the cabinet, the same being toreshortened. Figs.- 4 and 5 are detail views of the hinge connection between the gate and the base of the cabinet.

Referring to the drawings, the numeral 9 designates the open base or frame of the cabinet 7 and is mounted above a sewage re-, ceptacle. Surrounding the opening 8 are the lower upstanding walls 11 and the two end walls 11, the upper ends of which are inclined to co-act with the respective doors or gates 15 to permit the gates to assume the position as shown in Fig. 2 to seal the open-. ing 8 and thereby prevent the odors from the excrement escaping and at the same time retaining the temperature at the proper degree in the receptacles for the more rapid liquefaction of the sewage.

Mounted upon the base 9 at each side of the rims 11 are the two pivots 12 having the two disk ends 12 for the reception of the truncated portion 13 of the gate actuating lever 14, which as shown are connected to the respective gates 15 and have their free ends 16 projecting outwardly and below the lower edges of the metal casing 10 of the cabinet. The casing 10 is provided with the inturned flanges 17 for the reception of the seat 18, provided with the usual opening 19. When the seat and casinglOis in the normal position, that is the gates being normally closed by the weights 15, the casing and seat will be elevated. If the seat is occupied the same will be moved downwardly to assume the position as shown in Fig. 2 and consequently elevate the doors or gates folrl the introduction of the excrement to the ce s.

By mounting the covers of the gates 15 as sh wn the levers 13 are readily movable into thri proper position as there 1s no necessity of an extra means for holding the levers downwardly upon the respective pivots 12.

The casing 10 may be readily lifted from the base 9 and thus permit the ready access to the opening in the air tight covers of the respective casings 2 when necessary. The casing 10 may also be removed and the gates 15 remain in closed position to prevent the escape of odors therefrom, and as the said gates 15 are air and light tight, as before stated, the process of liquefaction is more readily carried on.

What is claimed is:

l. A commode cabinet for a sewage disposal apparatus, a base provided with a rectangular excrement receiving opening, an upstanding open frame upon the base and surrounding the opening, said frame having two opposed walls having inclined edges diverging downwardly from the center, two gates disposed to engage the upper edges of the frame and seal the opening of the base, co-acting means carried by the base and gates for forming a hinge therebetween, and a vertically movable seat carrying casing resting upon and disposed to actuate the members of said means carried by the gates to open the gates when depressed, and counter balancing weights carried by the gates to normally hold the casing elevated when the :gates are closed, the depression of the casing due to the occupancy thereof actuating to open the'gates.

2. A closure for a sewage disposal apparatus, having a flat base provided with a rectangular opening, a rectangular frame mounted upon the base and forming upwardly projecting walls for the opening,

' two of the opposed walls thereof being of greater height than the other two walls and.

having their upper edges-inclined and diverging from a longitudinally central point of the frame downwardly to the junctions with the remaining two walls, the upper edges of all walls being recessed near the inner faces thereof, two stationary pivots carried by the base exterior of each lower wall of the frame, two gates for resting by ravity upon the upper edges of the open rame to seal the opening of the base, two gate actuating and fulcruming levers connected to each gate near one edge, said levers having portions to rest removably from above and upon the stationary pivots, the

outer ends of the levers projecting outwardly beyond the pivots, and a vertically movable seat'carrylng open ended casing havin slots in its edges upon two sides, said s ots registering with the outer ends of the levers, said gates normally over-balancing the seat carrying casing to hold the cas'-' ing elevated, the occupancy of the seat lowering ,the casing and opening upwardly the gates.

In testimony that I claim the foregoing as my own, I have hereto aflixed my s1gna-' 30 ture in the presence of two witnesses.
