Application filed October 5, 1912. Serial No. 724,059.

To all whom t may concern Be it known that I, ANNA C. CLARKE, va citizen of the United States, residing at Scranton, county of Lackawanna, State of Pennsylvania, have invented certain new and useful Improvements in Sewage Systems for Railway-Cars' and the like; and I do hereby declare the following to be a full, clear, and eXact description of the invention, such as will enable othersjskilled in ratus, together with means for regulating` the water pressure; and to provide an 1mproved form of tank for receiving the sewage, associated with means for readily attaching and detaching the tank with respect to the car and establishing an efficient connection between the openings of the tank and the sewage waste pipe and the vent pipe when the tank is adjusted to position in its supporting devices.

The invention is illustrated in the accompanying drawings, in which- Figure 1 is a side elevation partly in section of the body of a railway car having the invention applied thereto. Fig. 2 is an end view of the car body, partly broken away to illustrate the relative arrangement of the parts of the sewage system. Fig. 3 is a longitudinal vertical 'section through the improved sewage receiving tank. Fig. 4 is an end view showing a tank closure and its attaching means. Fig. 5- is an'end View of the tank with the closure removed. Fig. 6 is a section of one end ofthe tank showing the means for securing Vthe closure thereto. Fig. 7 is a sectional, view of the three- `way valve for directing the sewage into the tank or to the open discharge. Fig. 8 is a detail view of' one of the tank supporting beams. Figs. -9 and 10 are frontfand side elevations of the tank supporting brackets by which the beams are carried. v

Referring to the drawings, A indicates the body of a standard passenger car yp rovided with the usual toilet accessories, of which indicates the closet bowl to the discharge end of which Yis attached a fitting provided' with a three-waycvalve 2, one side 'of :which connects with a` sewage pipe 5 running toward the middle of the car and adapted to be attached its free end to the inlet of a sewage receiving tank, to be hereinafter described. `The other side of the three-way valve is connected with a pipe 3, provided with an open discharge to direct the sewage out of the car and on to or adjacent the right of way. The said threeway valve 2 is providedA with a suitable handle 4, which is preferably extended to a point outside of the toilet compartment, so as to be accessible tothe proper person on the carv or train to operate the valve to direct' the sewage either into the receiving tank or to the opendischarge on to the right of way. a

It will be understood that the invention .is not limited in itsapplication to sewage from closet bowl, but may also be applied to the'disposal of waste from basins, sinks, lavatories and other accessories of like nature common to railway-cars of the usual type t A suitable storage tank 6 for flushing water is mounted at any convenient location in the vicinity of vthe toilet compartment and is adapted to be connected with an eX- ternal water supply by means fof a suitably valved -pipe 7. The upper part of the tank vis provided with an outletpipe 10, which extends downward into the body of the tank to a point near the bottom thereof and is connectedfat its otherl end with'the usual inlet valve of a Hush tank 11,' which latter is connected by flush pipe 12 with the bowl 1. In order to supply thel necessary pressureto force the water from tank 6 into the flushtank j11 and to maintain anequal Vpressure of waterat all times, the tank 6 is preferably connected by a valved pipe 8 with the air pressure system of the train brakes, proper regulation of the airentering the tank being effected by a 'pressure regulator 9'located in pipe l@adjacent the bottom of the tank 6.

The sewage receiving tank 20 consists of a cylindrical shell, having secured at its ends, by rivets or other appropriate means, flanged rings 21, each formed on its outer face with a seating rim adapted to cooperate with a corresponding seating rim on leakage.

the closure 24. Each of said end closuresy 24 is reinforced by crossed ribs formed integrally therewith, the upper ends of which are provided with hooks 26 adapted to engage and embrace lugs 22 on the rear face of the coperating ring 21 as particularly illustrated in Figs. 4, 5 and 6. The opposite edge of each closure 24 and each ring 21 is provided with registering openings to receive a threaded bolt 28, the hole 23 in the ring being screw-threaded, while the hole 27 in the closure is slightly larger than the bolt 28 to admit of the latter being screwed into position and thereby draw the` seating rim on the closure into close contact with the coperating rim of the ring 21 and effectively sealing the tank against This construction of tank admits of the closures being readily removed for emptying the sewage and for flushing out the tank in the most effective manner.

The under side of the tank 20 is provided at each end with a saddle 37 riveted to the tank, said saddle having a relatively long flat horizontal bearing formed by pendent anges 41 having pin-receiving lugs 38 eX- tending therefrom. Each of said saddles is adapted to slidably engage an inverted channel bar 43, the opposite flanges of which are suitably notched as at 44 to receive locking pins 39 by means of which the tank is locked securely in position to the two beams 43. Said beams 43 are detachably supported in the forked ends 41 of brackets 40, which are disposed in pairs on opposite sides of the car and the ends of each beam 43 are locked to the brackets by pins 42 passing through perforations in the forked ends of the brackets 40 and engaging notches 44 in the pendent flanges of the beam. Said beam is strengthened by means of a truss rod 45 which is secured to the beam 43 by means of end blocks 47 and a central casting 46. The blocks 47 are provided with longitudinal perforations adapted to receive the end of a bar to admit of the beam being raised and lowered to position by the man whose duty it is to remove the full tanks and replace them with empty tanks.

The connection between the tank and the sewage pipe leading from the closet bowl or other toilet accessory is effected by means of the construction shown in Fig. 3. The discharge end of the sewage pipe or conduit 5 is tapered as at 5 to make a close airtight lit with a rubber gasket or washer 31 which is securely held between a seating ring 30 riveted to the tank and coupling flange 32 secured to said ring by means of bolts or the like. The coupling flange 32 is provided with an opening somewhat larger in diameter than the end of the pipe 5 and said opening is screw-threaded on its interior to receive a screw-threaded plug to seal the tank when the same is removed from the car and while it is being taken to the proper place to be emptied. The vent pipe 33 which is permanently attached to the car and passes upward through the walls thereof to a, point above the roof, is attached to the tank by a similar hermetic seal consisting of a rubber gasket 35 cooperating with the tapered end 33 of said pipe 33, said gasket being held between a seating ring 34 riveted to the tank and an interiorly threaded cap 36 adapted to receive a plug to seal the vent opening in the tank when the latter is removed.

In applying the invention to its intended use, the tank is secured to the car by two workmen, each of whom inserts a bar in the opening in block 47 and lifts the corresponding beam 43 until the corresponding locking pin 42 can be withdrawn, after which each of the beams 43 is lowered until its end rests upon the ground adjacent the railway track. The empty tank is then applied to the beams so that the saddles 37 engage the two beams and the said tank is shoved forward along the beams until the openings in the lugs 39 of the respective saddles come opposite the notches 44 in the beams 43 at which time the locking pins 39 are passed through the ears 48 and the notches 44, 44, whereby the tank is securely locked to the beams. The workmen then lift the ends of the respective beams by means of the bars engaging the blocks 47, until the free end of each beam engages the forked end 41 of the coperating bracket 40, whereupon the locking pins 42 are passed through the perforations in the forked ends of the brackets and notches 44 in the beams, and the tank andl its supporting beams thereby securely locked in position. It will be apparent that the tank may be applied to or removed from position from either side of the car, inasmuch as the supporting beams 43 are attached to brackets 40 in the same manner at each end. As the tank is thus moved to position, the sewage inlet opening and the vent opening to the tank are both brought into registry with the liXed tapered ends of the sewage conduit 5 and the vent pipe 3 3, with the result that said tapered ends are forced into close air-tight engagement with the rubber gaskets 31 and 35 respectively, mounted adjacent said openings. When the tank is to be removed from a car, the operation is reversed, that is to say, the beams 43 are cast loose from their bracket vsupports on one side of the car and the Vfree ends of the beams dropped to the right of way. This separates the tank from the' pipes 5 and 33, after which the fastenings between the tank saddles and the beams 43 are removed and the tank slid along the inclined ,beams 43 until free of the` same, when it can belifted by the workmen and conveyed to the place of ultimate disposal of the sewage. After a full tank has been removed, an empty tank is applied to the beams and the latter adjusted to locked position, as hereinbefore described. As soon as the full tank has been removed, the sewage inlet opening and the vent opening are closed by means of screw plugs inserted by the workmen in caps 32 and 36 respectively, if found necessary. The full tanks may be conveniently handled by suitable trucks equipped with cranes for lifting the tanks thereon, and, of course, may be transported to any suitable or appropriate place for ultimate disposal of the sewage. The tanks are emptied by removing one of the closures 24, after which the other closure 24 may alsobe removed and flushing water turned into the tank, open at both ends, t0 effectively clean the tank.

The tank is intended to be used in all localities where contamination of the soil or of streams would be likely to occur from sewage discharged from the car, and when traversing such localities, the three-way valve 2 is turned to discharge all of the sewage from the car into the tank. When, however, the car is passing through sections where contamination of streams cannot occur or where contamination of the soil of the road bed is immaterial, the three-way valve may be adjusted by the attendant on the car to direct the sewage by way of pipe 3 to the open discharge.

The entire system as hereinbefore described, is adapted to be applied to any standard railway car or similar conveyance, without materially changing the usual form or arrangement of standard sewage appliances, it being necessary only to attach the tank supporting devices to the under framing of the car, to mount the water storage tank and its air pressure connection at some point convenient to the toilet compartment, and to apply the three-way valve and its connected conduit pipes to the discharge outlet of the bowl or other toilet appliance.
