LATRINEAND WATER-CLOSET.

SPECIFICATION forming part of Letters Patent No. 284,976, dated September 11, 1883.

Application filed April To all whom, iin/tay concern:

vtrated.

Be it known that I, VALTER E. PARFITT, of Brooklyn, Kings county, New York, have invented certain new and useful Improvements in Latrines and Water-Closets, of which the following is a specification.

My invention relatesmore especially to what are known as latrines7-that is, elongated waterclosets having a common receivingchamber or water-trough over which a number of seats are tted, and discharging at one end into the sewer, such as adapted for schools, barracks, and public places. My invention, however, is also adapted for ordinary or single water-closets when `so desired; and it consists in the peculiar construction, arrangement, and combination of parts, as hereinafter more fully described and claimed. Y

Figure l of the annexed drawings presents a longitudinal section of my improved latrine, and Fig. 2, a plan view thereof, shown partly in section, on the line x a: of Fig. l.

In these figures, a a indicate the receivingchamber of the latrine, which has the usual shape of an elongated water-trough, as shown, and is made of Isheet-lead, as represented in the drawings, supported in and inclosed by a wooden frame or casing,b b. The trough or body of the latrinemay, however, be made`of hydraulic cement, or of brick or iron, or of any other suitable material, as will be readily understood by architects, plumbers, and other experts.

Over the receiving-chamber a is arranged the seat or cover c, which is preferably hinged to lift up, as usual, and is provided with a number of individual openings, as shown, more or less, according to the length of the latrine. At the initial end of the receiving-chamber is a flushing-chamber, d, containing ,the flushing devices, as hereinafter described, and this end of the chamberhas an inclined base, e, as illusrlhe terminal end of the receivingchamber has also an inclined base, which forms a dam or Weir, f, of limited depth, adjacent to which a free discharge outlet or neck, g, opens, and into which the water running over the dam escapes freely to the sewer, asuitable trap being of course arranged between thev discharge-neck g andthe sewer, as will be underv stood.

into this receiving-chamber extend the waterpipes 1J k, arranged to discharge directly into the tank m, so as to charge the same either constantly or intermittently. The larger pipe, i, may connect with the rain-leaders from the roof, or with waste-pipes from the several sinks and wash-basins of the house, or with bathtubs, so as to convey all the rain and waste water to the latrine, and thus serve to utilize the same for more cffectually iiushing the latrine. I prefer, however, in allcases to provide a smaller pipe, lf, to convey a constant and independent supply of fresh water from the regular water-service pipes to the flushingtank. This pipe is provided with a cock, n, which may be adjusted to deliver a constant stream into the tank on, and of greater or less volume, according to the size or extent of use of the latrine, as will be understood.

A door, o, in the side of the flushing-chamber permits access to the several parts for examination or adjustment, which may be afterward closed and locked, to prevent mischievous tampering with the mechanism.

The iiushing-tank m is preferably provided `with short trunnions p on each side, near its center of gravity, which trunnions pivot on socket plates or ears r r, affixed to opposite sides ofthe fiushing-chamber, as shown best in Fig. 2. The flushing-tank is thus capable of being freely turned on its pivots and dumped in the chamber, as indicated lby dotted lines in Fig. 1; but the tank is so weighted that when empty, or nearly so, it will always 'assume an upright position, as indicated by full lines in Fig. l, where its mouth will underlie the water -pipes i k and receive the water therefrom, as illustrated; It will be noted, however, that the upper part of the tank has greater capacity on one side of the pivot-line-that is, on the side toward the discharge end of the latrine. Consequently when the tank becomes filled nearly to the top the tank becomes overbalanced and automatically tips or dumps, as indicated by dotted lines in Fig. 1, thus suddenly discharging a large mass of water into the water -trough or receiving-chamber a,

which -produces an energetic surging wash therein, and causes a wave to sweep toward the discharge end, carrying the soil or other mathas dumped its charge of water, it will of course immediately rise to receive a fresh charge, after which the same operations will be repeated at regular intervals and more or less frequent, according to the volume of water flowing from the pipes z' k, thereby cleansing the latrine in a manner which is perfectly automatic, and at the same time certain andAv This system, as will be readily noted, i

simple. is .both economical in the vuse of water and energetic in the cleansing action, for, obviously, a volume of water discharged suddenly in a mass at intervals into the receiving-chamber will produce a more thoroughand certain cleansing action than would a larger volume of water if allowed to ilow continually throughl the chamber.

It will be noted on reference to Fig. l that each end of the water-trough is inclined, the incline at the discharge end forming the dam f, and the incline at the initial end being just below the tank m. By this means the mass of water is of wedging form at each end, and is thus easier set in motion. Consequently when the tank m is dumped, the mass of water being suddenly precipitated upon one end of the wedge, tlie whole mass moves easily and in a powerful wave toward the opposite end, where the wave easily rides over the inclined dam f and precipitates itself, together with the oating soil, into the discharge g, thus rendering the action `easy, quick, and energetic.

I do not wish to infer any broad claim to an automaticallytiltingor dumpingflushing-tank, in combination with the receiving-chamber of waterclosets or like structures, as several former instances of such an idea can be given. In all such eases, however, the tank has dumped into an ordinary form of water-closet bowl with inclining sides and with a free discharge-outlet at or about its center, whereas in my case the receiving-chamber is an elongated trough with a shallow dam at one end and a free discharge-outlet` adjacent thereto, and at the opposite end is arranged the dumping-tank. By this construction a limited depth ofwater always remains in the trough and the excess freely lows over the terminal dam into the free discharge-outlet, while the intermittent dumping of the flushing-tank in the opposite end of the trough causes a powerful wave or surging action of the water from the initial to the terminal end of the trough, which causes all deposits to` be swept energetically over the dam and dashed into the outlet, whereby a very effective cleaning action is produced, and which presents a greatly improved form of latrine.

I am also aware that a sewer-vault has been provided with an automatically tilting or dumping flushing-tank, as shown in the patent of Dark, No. 91,828, of January 29, 1869; but

in this case the dumping-tank was placed outside and remote from the vault, and arranged to dump into a funnel-pipe which led into one end of the vault. The vault or watentrough was not inclined at each end, and the parts were not arranged so as to secure the energetic wave action from one end of the trough to the other over the terminal dam, for in this case the trough did not have a free dischargeoutlet over the dam at the terminal end, for a partition, g, depended down into the water in front o'f the dani, forming a trap or water-seal, so that the wave, rwhich would in my case sweep freely over the dam and carry with` it all floating matter, would in this reference be obstructed by the pendent sealing-partition and have no such eifect.

What I claim isl. A latrine having its water-trough inclined at each end, with a free discharge-outlet beyond the incline, a dumping-tank pivoted directly above the incline at the initial end, a feeder for supplying water to said dump-tank,

and a water-pipe for supplying water continuhaving valve n, all combined and adapted to serve, in relation to the cover c and outlet g, as set forth.
