Specification of Letters Patent.

Application filed August 15, 1907. Serial No. 888,680.

To all whom it may concern:

Be it known that I, ANNA C. CLARKE, a' citizen of the United States, residing at Scranton, county of Lackawanna, State of Pennsylvania, have invented certain new and useful Improvements in Sewage Systerms for Railway-Cars; and I do hereby declare'the followin to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention relates to apparatus for the disposal of sewage and the like from railway cars, and is intendedto be ap lied in connection with water closets, sinks, avatories and the like, for the purpose of catching and retaining the discharge therefrom to prevent such discharge being deposited on the right of way, as is thepresent practice on most railroads.

The deposition of refuse from railway cars onthe right of way and more especially where the matter consists of human excreta, is undoubtedly the source of contamination of many water sup lies and is also a positive menace to the heath of passengers on the cars, as well as that of persons working upon or living adjacent to the right of way.

The present invention has for its object to provide means for catching, and retaining such refuse matter in a propriate ree ceptacles or reservoirs carrie by the cars, from which said matter may be discharged at appropriate places, the reservoirs being either stationary or removable, and having appropriate connections with the waterclosets, lavatories or sinks on the cars and, when the reservoirs are removable, suitable flexible connections between the same and the bowl of the closet, lavatory or sink, as the case may be, are provided. The reservoir is also preferably provided with a vent pipe or stack which, when the reservoir is removable, is also provided with a flexible and removable coupling or connection with the reservoir.

In the accompanying drawings, Figure 1 shows the end of a car in side elevation, partlybroken away to illustrate the invention as applied to a water closet; Fig. 2 is a side elevation of a convenient form of reservoir. Fig. 3 is a longitudinal section through the same. Fig. 4 1s a transverse section of the reservoir showing also a convenient means for removably securing the same in place on the car.

The invention has been shown in connection with a water closet merely b way of illustration or example, and it is to e understood that it is likewise applicable to lavator1es, sinks, urinals and the like, and that the, claims are intended to be interpreted accordingly.

In the drawings, a indicates the hop er or bowl of a water closet, which may e of any preferred form provided with the usual trap to prevent the escape of ases or efliuvia into the apartment. Suspen ed from the body of the car and preferably in the most convenient and accessible location is a tank or reservoir 6, adapted to be connected with the outlet of the closet bowl. In its preferred form, thelreservoir is a cylinder of metal closed at each end by re movable heads 71, held in waterand gas tight contact with the cylinder ends by means of yokes j and set screws 70. If desired, one end of the cylinder may be perma'nently closed and the other provided with a removable head.

Near one end, the tank 6 is provided with a nipple 0 adapted to, receive a tubular connection d attached at its other end to the outlet of the bowl a. If tank 6 is removably secured to the car, connection d may conveniently be made of a section of rubber hose or piping, one end of which is passed into niple 0 and through a rubber packing e to ef-. ect a gas tight fit. If the tank is permanently attached to the car, it may be connected with the bowl by any suitable permanent coupling or piping.

In order to properly vent tank I), it is connected with a stack or pipe Z, which is preferably carried up above the car roof so that air and noxious gases may escape from the tank, without annoying or endangering the passengers. With a permanently attached tank, said stack may be rigidly attached thereto, but when the tank is intended to be removed, the stack is connected therewith by a short section of rubber piping or hose g threaded through a nipple h and packed by a rubber gasket 7.

In order to removably attach the tank I) to the car, any appropriate supports or suspending means may be provided, a simple and efficient apparatus for the purpose consisting of pendent brackets n, secured to the under side of the car body, each having a horizontal bottom member 10 and a hinged Patented May 17,1910.

outer side member 0, adapted to be swung down to permit the insertion or removal of the tank, and when turned up to be locked osition by a set screw an nut s. The is held firmly in position agamst lateral movement by the bracket sides and against endwise movement by lugs m on the bottom of the tank which embrace the horizontal members of the brackets. t

The operation and utility of the invent on will be apparent from the foregoing description. Matter deposited in the closet, urinal, lavatory or sink on the car'will be carried directly into the tank band retained therein until the car reaches the proger'place for discharging the contents of t discharge being efiected either'by removing the tank as a whole and replacing it byanother, or by opening one of the heads or closures and ermitting the matter to flow out.

The cylindrical form of the tank permits it to be readily cleansed by flush ng, and all of the parts of the apparatus belng capable of thorough cleansing and dismtectmg, a

a thorough sanitary condition of the same may be maintained.

In order to facilitate the emptying of the tank without removing the heads when said tank is *provided with removable heads, the inlet nipple 0 may be employed as a discharge when' the tank itself is removable. On the other hand, when it is desired to dis-' charge the contents of the tank when the latter is stationary and more particularly when it is not provided with removable ends, a

e tank, such 2, may be rovided, so that b valve :12, t e contents will ow odt, and should any solid matter rema' in the tank,- it ma be flushed out by a stream of water intro need through the inlet nip 1e 0.

What I claim as my invention 1s:-

1. A sewage stem for cars and the like comprising, the atory or the like,

opening the a removable closed tank having means for discharging its contents and rovided with an inlet a flexible conduit eading from the bow and separably connected with the tank-inlet and means for separably supporting the tank from the car. 2. A sewa e system for cars and the like comprisin e bowl of a closet, urinal, lavatory or t e like, a removable tank having ,an inlet separabl connected with the outlet of the bowl, or t e like, and provided with guide lugs, and straps suspending the tank rom the car with t eir lower members extending throu h said guide lugs, said stra s having hinge sections to permit of t e ready removal of the tank. 7

3. A tank for car sewage systems, provided with a removable'head, an inlet, a vent, and guide lugs on its lower side.

In testimon whereof I aflig my signature, in presence 0 two witnesses.
