3 Claims.

This invention relates to portable toilet rooms and more particularly to an auxiliary cess. tank adapted to collect and temporarily retain the more solid parts of the refuse commonly deposited within the toilet hopper. Ay generalobject of this invention is to provide improved means in the form of an'auxilia'ry `cess tank secured below but inclosing the drain spout of 'a portable'toilet in a manner'that' adapts saidl cess tank to collect and temporarily retain' the more solid parts of the refuse commonly deposited v within thehopper of said portable toilet.

A rspecific object of this'invention is toprovide improved means for conveniently controlling the removable bottom of an auxiliary cess tank whereby said tank may be used to collect and retainthe more so-lid parts of refuse commonly deposited within the hopper of a portable toilet with which said tank 'is associated, and, vice versa, said controlling means providing for conveniently opening said bottom of said cess tank whereby said cess tank offers no obstruction to the flow of refuse commonly flushed through said portable toilet.

Another specic` object of this invention is to provide 'improved means for controlling an auxiliary cess tank, designed tobe associated with a portable toilet, of such form that the operating handle of said controlling means may be located l convenient to the hand of the care-taker and out-of-the-way of the user of said portable toilet, whereby said handle may notbe disturbed by said user but may be quickly and conveniently operated by said care-taker to close or open said cess tank.

' Anotherspecic object of this invention is to provide improved means in an auxiliary cesstank and controls of forms suitable to' be associated with standard forms of portable toilets, such as used in Pullman cars, other standard passenger cars, and house trailers, whereby the porter in charge of the particular vehicle may conveniently and quickly close said auxiliary cess tank when said car stops at a station and/or open said auxiliary cess tank when said car has moved away from said station.

Another object of this invention is to provide improved means in an auxiliary cess tank and controls in forms adapted to be installed on standard vehicles Without interference with structural parts of said vehicle.

Various other objects and advantages will be apparent as the nature of the invention is more fully disclosed.

In the accompanying drawings are shown the 2 novel features and construction of. one` embodiment ,of the device'according to the present invention:`

In the following description certain speciiic terms vare used for convenience in referring to various details of the'invention. These terms, however, are to be given as broad an interpretation as the state of the art will permit.

Referring now more particularly to: the accompanying drawings, the following is a description Vthereof wherein like and corresponding parts` are designated by similar reference characters.

In `the' embodiment of the invention disclosed numeral I represents the walls of a tubular auxiliary cess tank which incloses the drain spout 2 of a portable toilet.v Said cess tank is secured tothe floor 3 of a portable toilet room, ona standard vehicle, by means of projections 4 and bolts 5, and said cess tank is spaced below said iioor 3 by means of spacers I5. Nearr the top of said cess tank I screen openings I permit excess water to drain out, the more solid parts of the refuse commonly deposited within the hopper 8 of a conventional toilet for vehicles being retained within said tank I when the bottom 9 is closed. Said bottom 9 is secured to a shaft I B by an arm 9a which pivots in a tube II that is se* cured to projections I2 and I3 of said tank I. Said tube II and shaft Ill extent approximately vertically but may be inclined away from said hopper 8 when necessary to avoid interference with existing structures.

Shaft I0 and bottom 9 are operated by means of a lever I4 which is adapted to be operated by the foot of the porter in charge of said portable toilet room. Said lever I4 is connected to the upper end of shaft I0 in a common manner; the

produced by twisting a solid square bar, and when made slidable through a square hole as shown in the nut I1, Fig. 6, this provides a rotating action of said shaft I that closes and opens said bottom Q'Withthe upward and downward movement, respectively, of said shaft I0. A roller rests Within the saddle of a rubber cushion 2l in a manner adapted to support the weight of said bottom 9 and conjunctive parts, and hold, by its resiliency, said bottom 9 against the lower end of said tank l. Said rubber cushion 2i is ysupported by the base plate 22, and retained between extensions 23, 24 of said base plate 22. Near the central part of said lever I4, downward extensions 34 retain a pin 35'. and said roller 20 concentric with said pin 35 between said extensions 34. Said extensions 2.3, 2.4 also retain the ends of said pin 35 which slide freely .within vertical slots .cut within said extensions 23, 24. Said lever IA is held in closed position, as shown in Fig. 5, by means-of atoothed pawl .33. Said pawl 33 is held in active position, asshown in 5, by means of .a -compression spring .25, )which rests upon said base plate22. To opensaid bottom 9, said DaWlBSis releasedby the foot of said porter inchargaupon the vextension 2-1 of said pawl 3.3 as .the .Weight of said bottom 9 depresses itheend of said lever I4 that retains, the upper vend of said shaft ylll. The weightof said porters foot may be added when necessary. Said shaft l and thereby said bottom 9.a.re positioned exactlyfbythe adjustment plate Il in the following manner: The screws or bolts 3B. 3| are loosened and said plate l1 turned until said bottom 9 is in thecorrect closed position and then said fastenings 30, 3| are secured.V lSaid base plate 22 ,is securedto the floor 3..of said portable toilet room in a common manner by .bolts .and

screws.
