To all lwhom t concern:

Be it known that we, JAMES M. TEAHEN,

i a citizen of the United States of America,

. chietly, in large residing atDetroit,- in the county of Wa ne and State of Michigan, and WILLIAM Axiioir, a subject of the King of Great lBritain and ireland, resielin at'Fo'rd, in the Province of Ontario an Dominion of Canada, have invented certain new. and use llmprovements in Water Closets, of which the following is a specification, reference being, had therein to the accompanying drawings;

ilhe invention relates to water closets and has for its object the obtaining` of a construction in which y tank are incorporated in a single integral 4 ixture conforming to the ordinary or extraordinary roughing-in measurements vrequired by plumbing practice.

in the present state been reasonably standardized, the ordinary construction thereofv being trade styled or named and requiring, as thus trade, certain standardizedv roughing-in measurements, meaning by this,- the distance between the center of the soil vpipe or other ttingopening in the floor and theewall in rear of the closet.

There are two types of Bushing apparatus in general use, the more conunon bei-ng the gravity system, where the water is sup lied to the bowl from the tank or cistern, and the other the pressuresystem, inwhich the inflowing water is delivered directly from the water supply into the bowl. As the latterv requires a relatively large volume to be discharged directly from the main, it is used buildings provided with their own water-'supply systems, but the construction'incommon'use is the gravity flush. With this, the'fltank or 'cistern is a separate fixture, usually/hung upon the Wallin rear of the bowl and abeve the level thereof, being connected thereto bypipe fittings.

it is the object of the present invention to simplify the construction by the substitution of a single unit for the two units required in the rgravity flushing system. lt is, however, trade important, meaning plumb-` ing practice, sions so far as they effect the general accepted roughing-in measurements, and also to obtain a construction which is commercially standard both as to bowl and siphon'trapf Specification of Letters Patent.

It is also important to `aord stable support for the tank without the necessity ing the base or pedestal ofthe fixture or the requirement for any other supporting or stabilizing connection. This result is accomplished by a construction where the tank is integral with the bowl and is stably support' ed on the same pedestal. rllhe required capacity is obtained either b utilizing the space between the bowl'an the rearV wal provided by standard roughing-indimen.

of enlargl sions or by extending the tank symmetrr' cally upon oppositesides lof the pedestal or by a combination of both. The tank is also preferably' located in the main between the level of the water seal and the top of the bowl, which permits of a gravity discharge andl avoids an objectionable increase inV height of the fixture.r

lln detail and as shown inthe drawings:

A. is the bowl proper provided kwith'the usual hollow rim lB andhas its lower end connected with the siphon trap C,includ ing the return-bent portion D and at its lower end, which connects with the nipple F for coupling with the soil pipe. G is the'supporting base within.which the trap is located. H is the flushing tank,the bottom of which is preferably arranged slightly above the level of -the water seal indicated at ll, and which extends rearward from the bowl and trap to within extending portion E the laterally a short distance of the rdughing-in limit.

llzaterally the tank `is extended on each Vside ofv the bowl a distancel Whichwill be within roughingin measurements. There is also provided a connecting channel l between the bottom of the tank and the bowl, thevport J Jopening '-into'the -b "wl, being preferably to produce a tangential jet also being preferably below of the water seal. thus f r described so'v arranged as movement and the normal level The constructiong .as maybe used withga'ny'. suitable"A struction *of Hush valve' and .Heat-controla et, these parts being n QtSo provision may ico be inade for a rim flush and l have indicated an inlet channel K from the tank to the rim, the upper end of which is above the high level in the tank and the water for this rim flush rnay be taken directly from the supply, butthemechanism `for accomplishing this forms no part of the present invention.

ln operation, when the flush -valve is actuatedto open the port J2, which connects the tank with the'channel J, the water with'- in the tank will be discharged into the bowl to raise the level therein to an equalizing line, such as indicated at L. This will cause the overtlowingof lthe trap and the forming 'of a Siphon,` whereupon the siphonic presstruction could be placed in locations where the standard roughing--in dimensions have not been' complied with and where, theretore, `there isA not the requisite' clearance vllin theback oi the bowl 'for the construction shown in .Figures l to 3. The two constructionsare, however, the same, in that in each there is .a comparatively small head ot liquid `for effecting the discharge from the tank to the bowl and the velocity is obtained by siphonic action.
