WATER-CLOSET.

SPECIFICATION forming part of Letters Patent No. 474,682, dated May 10, 1892. Application filed October 22, 1891. Serial No. 409,467. (No model.)

To all whom t may concern:

Be it known that I, ARTHUR OBRIEN, acitiaen of the United States, residing at Helena, 1n the county of Lewis and Clarke and State of Montana, have invented certain new and useful Improvements in Water-Closets; and I do hereby declare the following 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.

My present invention has reference to 'wash-out water-closets, the object being to improve the general construction and operation of such apparatus and to provide improved means for preventing the overflowing of the bowl and for Ventilating the bowl and soil-pipe.

To these ends my invention consists in .forming an annular chamber above the flush- 1ngrim, which has connection with a vent and an overflow-pipe, and with the interior of the bowl through a series of passages, this chamber serving the purpose to carry off the ovcriiow, and for ventilation. t

My invention also consists in the general construction and arrangement of the several parts constituting my improved water-closet, all of which will be hereinafter fully described, and specifically pointed out in the claims.

In theaccompanying drawings,which form a part of this specification, Figure l represents in top plan view, partly in'section, my improved water-closet adapted for dwellings. Fig. 2 is a central vertical section, Fig. 3 an inverted plan view, Fig. et a front elevation, and Fig. 5 a rear elevation, of the same. Fig. 6 is a top plan View, partly in section, of a closet adapted for use in connection with prisons or the like; Fig. 7, a vertical central section, Fig. 8 a rear elevation, and Fig. 9 a front elevation, of the same.

Like letters of reference refer to like parts throughout the several iigures of the drawings. i

Referring first to the construction shown in Figs. l to 5, inclusive, A represents the bowl, which is of porcelain, and formed with the usual basin d, trap a', and soil-pipe co2. The flushing-rim h is inclined slightly from front to rear, it chamber b having connection with the interior of the bowl through an annular passage b2. This chamber terminates at its rear in a branch b3, to which is connected a water-supply pipe. (Not shown.) c is an annular channel formed integrally with the bowl, and located above the flushing-rim. It has connection with the interior by means of a series of openings or passages cand terminates in a branch chamber o2, as shown. This branch chamber leads to two passages d e, one of which CZ forms a vent and extends upward and communicates with a vent-pipe. (Not shown.) The other passage e extends downward and forms an overflow, as will be presently explained. fis a vent formed in the wall of the soil-pipe immediately below the basin, and which communicates with the overflow by means of a suitable pipe f. (Shown in dotted lines in Fig. 2.) By means of this con struction a thorough ventilation of the bowl and soil-pipe is had at all times, the air from the bowl entering the channel c and passing olf through the vent leading from passage d and the air from the soil-pipe passing through the vent f, pipe f', overllow, and vent d, and as there is a constant draft through the seat-opening and vent-pipe the air in the rooml in which the closet is located is kept pure. In the event of the trap becoming clogged or from other causes the bowl should have a tendency to overflow, the Water when it reaches the passages c will pass by them to the channel'c, and thence to the overflow-pipe f', vent f, and be discharged through the soil-pipe; or the overflow may be carried off by a separate pipe, as will be evident.

In Figs. 6 to 9, inclusive, I have shown a construction embodying all the essential features in the foregoing description. This construction is, however, especially designed for use in connection with prisons or public places, and the changes are but incidental to this special purpose. The bowl is preferably of steel and is adapted to be secured bymeans of bolts or rivets to the wall or other upright; or screw-threaded lugs and bolts may be ernployed with equal facility. In this construction I dispense with the trap, the passage from the basin to the soil-pipe being substantially a direct one. The water is supplied at one side of the center, and is delivered through IOO the flushing-rim in the saine manner as that previously described, no change in the construction of said rim being made. The vent and overflow are formed in a casting g, made separate from the bowl, and is passed through an opening and connected with a screwthreaded socket h, made in the bowl-casting after the bowl is put in place. The operation is substantially the saine as that described heretofore Vwith reference to Figs. 1 to 5, with the exception that the ventilation ofthe soilpipe is had through the passages c', channel c, and vent-passage d.

It will be evident from the foregoing that by my construction I am enabled to produce a water-closet in which the operation is improved and rendered very effective and a perfect ventilation established. The parts are few, simple in construction, and very compact, and the liability to get out of order is reduced to the minimum.

I claim as my inventiony l. In a water-closet, the combination, with a bowl, of a channel formed integrally therewith and communicating with the interior of the bowl through a series of slots', a passage forming a continuation of said channel and arranged in a line coincident therewith, a

vent, and an overflow forming a continuation of said passage, an overflow-pipe connected. with the overflow, a flushing-rim below said channel, and a water-supply therefor, the

combination permitting a ventilation of the bowl and soil-pipe and the carrying off of the overllow through the same channel.

2. In a water-closet adapted for prisons or the like, the combination, with a bowl, of a channel formed integrally therewith and communicating with the interior of the bowl through a series of slots, an opening leading from said channel and arranged in line coincident with the channel, a coupling adapted to be passed through a wall or other support and connected with said opening,.openings in said coupling, having connections with a ventpipe and an overflow-pipe, a flushing-rim, and a Water-supply therefor, and an opening in the lower portion of the bowl for connection with the soil-pipe, substantially as andl for the purposes set forth.

In testimony whereof I affix my signature in presence of two witnesses.

ARTHUR OBRIEN.
