Application September 20, 1954, Serial No. 457,123

1 Claim. (Cl. 4-11) This invention relates to a mobile toilet and has par ticular reference wherein is disposed a plurality of toilet facilities and with the housing being supported by ground wheels that permit the device to be transported from place to place providing a temporary toilet facility for use in construction projects or the like.

It has been common practice heretofore on construction projects to build a temporary toilet that is usually placed over an opening formed in the ground, which use has resulted in frequently contaminating wells and generally creating an unsanitary condition, and it is the purpose of this device to avoid such unsanitary conditions, and to provide a construction that is readily connectible to a water supply line for providing conventional flush toilets and urinals, and with the flush toilets being connected to a flexible soil pipe that is detachably connected to the conventional sewer lines or to the Well known septic tanks.

A further and important object of this invention resides in a toilet assembly of the flush type that is connected with a soil line and with the soil line being connected with a water supply line whereby the soil line may be conveniently and easily flushed out when the device is to be transported to another site.

A further object of the invention resides in novel closure doors for a pair of toilet facilities that serve jointly as a closure door and as an adequate shield to afford privacy for an individual or individuals employing the toilets.

Novel features of construction and arrangement of parts will be more clearly apparent during the course of the following description, reference being had to the accompanying drawings wherein has been illustrated a preferred form of the device and wherein like characters of reference are employed to denote like parts throughout the several figures.

Referring to the drawings:

Figure 1 is a side elevation of a device constructed in accordance with the invention,

Figure 2 is a vertical transverse section taken substantially on line 2-2 of Figure 1,

Figure 3 is a fragmentary enlarged section illustrating the means for flushing the soil line,

Figure 4 is a horizontal section taken substantially on line 44 of Figure 1 and,

Figure 5 is a longitudinal vertical section taken substantially on line 5--5 of Figure 4.

Referring specifically to the drawings, the numeral 5 designates a preferably rectangular shape channel iron frame that constitutes the base member for the device. The frame 5 is supported by a pair of ground wheels 6 through the medium of the usual axle 7 and spring mountings 8. The draft device 9 having a hitch 10 is employed in a conventional manner for towing the device from place to place.

Rigidly fixed upon the upper side of the frame 5 is a floor panel 11, here shown as being substantially co-extensive with the frame 5. Fixed with respect to the floor 11 are end walls 12 and

side walls

13 and 14. A trans- 2,772,420 Patented Dec. 4, 1956 'ice verse partition 15 spans the device and is connected to the

walls

13 and 14 in any desirable manner and with the several walls and partition being of equal height adequate to permit an individual to stand erect therein. The wall 14 is formed shorter in length than the wall 13, providing a pair of door openings 16 that provide access to separate toilet areas A and B. A longitudinally extending partition 17 divides each toilet area A and B into

cubicles

18 and 19. A roof panel 20 overlies the upper end of the toilet areas and extends slightly beyond the

walls

12, 13 and 14. The roof 20 is bowed transversely, as clearly illustrated in Figure 2, and is slightly elevated to provide ventilating air openings 21 throughout the periphery of the device. The several wall panels, partitions and the roof panel are preferably formed of sheet metal. The floor panel 11 is likewise preferably formed of sheet metal and its surface may be roughened or corrugated to prevent slipping of an individual.

Closure doors 22 are hinged as at 23 to the corners of the device and serve to completely overlie and close the door openings 16. Each of the doors 22 are formed of sheet metal embodying a relatively wide panel 24 and an integral angularly disposed portion 25. The upper and lower ends of the doors are provided with a connecting web portion 26 serving to rigidly support the panel 24 and its adjacent angle portion 25, against flexing. As clearly shown in Figure 4, the doors 22 are of such width that when disposed in a predetermined open position will effectively block the view of anyone passing the device, thus the doors 22 serve the dual purpose as a closure device and as a shield for a person employing the toilet. Each of the doors are provided with a conventional hasp 27 through the medium of which the doors may be locked at such times as the device is not in use or when being transported. Adjustable ground props 28 are carried at each corner of the device and serve to rigidly brace the device, in use.

Disposed within each cubicle 18 is a flush toilet 29 of conventional construction. Disposed within the cubicles 19 are urinal troughs 30. Each of the toilets 29 have communication with a common soil pipe 31 rigidly supported upon the lower side of the frame, and with the soil pipe 31 extending longitudinally of the frame to extend slightly beyond one end of the device as clearly illustrated in Figure 5. The soil pipe 31 is provided with upwardly directed laterals 32 that have connection with the commode s 3 3 embodied in the toilets 29. It is desiralble in a device of this type that the soil pipe 31 be formed of steel as a means of reducing the overall weight of the unit. The extended end of the soil pipe 31, as in Figure 5, is preferably threaded at 34 for detachable threaded connection with a threaded ring 35 carried at one end of a flexible soil pipe 36. The soil pipe 36 at its opposite end has detachable connection with a sewer or septic tank connection 37 in any desirable manner. The soil pipe 36 during the transportation of the device is preferably stored beneath the frame 5 in any suitable manner. The opposite end of the soil pipe 31 is provided with a reducing coupling 33 that has threaded connection with a water supply line 39 that terminates in a conventional cut-off hose bib 40, through the medium of which a hose or other water supply line may be readily connected to the line 39 to serve as a means for quiclcly and conveniently cleansing the

soil pipes

31 and 36 when the device is to be transported to a new location. The urinals 30 are each connected with the soil pipe 31 by drain pipe 41 in a convenient manner. A water supply pipe 42, disposed at one side of the device is provided with a hose bib 43 for connection with a hose or other water supply connection. The pipe 42 serves as a water supply means to the flush toilets 29 and the urinals 30.

In the use of the device, when it has been transported to a predetermined location, it is positioned adjacent either a septic tank or a sewer line. The several props 23 are then lowered and anchored in supper-ting position to prevent shifting of the unit. The flexible soil pipe 36 is then connected with the soil pipe 31 and with the sewer or septic tank connection 37. A hose leading from any convenient water supply is connected with the hose bib 43. The doors 22 are then shifted to the open angular position as illustrated in Figure 4 providing an adequate clearance to permit the entry to the toilet areas A and B. Any desiralble means may be employed to fixedly position .the doors in the desired angularity Where the panel portion 25 serves to eflectively block the view to the interior of the device. Toilets 29 and the urinals 3t) serve in their customary manner for workmen or other employees upon a construction project. Now, when the device is to be transported to a new location, the hose leading to the hose bib 43 is disconnected and each of the toilets 29 are flushed to relieve them of any water standing within the flush tanks. The operator then connects a water supply hose to the hose bib 40, and upon opening the valve of the hose bib, water is continuously flushed through the

soil pipes

31 and 36, efiectively cleansing them of any accumulated sediment that would ordinarily create an unsanitary and undesirable condition. This flushing is continued over a predetermined period of time calculated to thoroughly remove any deposits within the soil pipes. The soil pipe 36 is then removed and stored beneath the frame 5 in any suitable brackets provided therefor. The props 28 are then elevated and the hitch coupled with any convenient draft device for conveying the unit to a new location. The doors 22 are preferably closed in latch position before the device is transported.

it will be apparent from the foregoing that a very novel and desirable toilet facility has been provided to effectively serve in that capacity for construction projects or as a convenient temporary toilet facility. The device provides a sanitary arrangement required under the codes of certain municipalities and effectively avoids the common unsanitary conditions now prevailing in temporary toilets disposed over an opening in the ground. The device is strong, durable, cheap to manufacture, is easily transported from place to place and is most effective for the purposes hereinbefore described.

it is to be understood that the invention is not limited to the precise details of construction but that changes are contemplated as readily fall Within the spirit of the invent-ion as determined by the scope of the subjoined claim.
