To ctZZ whom, ii may concern.-

Be it known that I, ISAAC l/V. DAY, a citizen of the United States, and a resident of Bridgeport, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in VVater-Closets, of which the following is a specification.

My invention relates to water-closets; and it consists in certain details of construction, to

ro be more fully set forth in the following specifcation.

To enable others to understand my invention, reference is had to the accompanying drawings, in which- Figure l represents a broken view of a water-closet bowl, supportingbase therefor, clamps for coupling the foot of the bowl to the base, section of the floor on which saidbase rests, broken section of the lead bend or 2o soil-pipe, and back air connection projecting from said base. Fig. 2 is a central broken sectional View ofthe bowl, sectional view of a shortsupporting-basewithout thebackairconnection and one of the clamps, and sectional view of the soil-pipe and floor. Fig. 3is an upper plan view of the clamps and base and section of the bowl through line ct a of Fig. l. Fig. 4 is a broken sectional View of one side of the bowl and sectional view of one side of the base. Fig. 5 is a detail side elevation of the filling-piece adapted to be placed between the ears of the Vclamp to complete the circle of said clamp. Fig. 6 is a detail plan view of the filling-piece. Fig. 7 is a detail cross-sec- 3 5 tion of one of the side clamps without the lining. Fig. 8 is a view similar t0 Fig. 7, showing the lining in said clamp. Fig. 9 is an enlarged broken view of one side of the bowl and base with one of the side clamps in position. Fig. lO is a detail broken view, partly in section, of one of the side clamps, showing the seat for the filling-piece. Fig. l1 is a detail perspective View of one of the packingpieces for the filling pieces or blocks. Heretofore it has been the custom in the construction of water-closets to set the foot of the bowl on the floor and secure it thereto by means of screws passing through the fiange of said foot, rst placing putty or other like cement between said foot and floor. The un- 5o evenness of the iioor and flange of the foot of the bowl made it difficult to screw the foot as firm as it ought to be, owing to the brittle nature of the porcelain of which the bowl is made. Consequentlyin the majority of cases the bowl rested very insecurely and loosely on the cement. The usual shrinking of the ioor would soon destroy the cement, so that in a very short time water would leak out between the foot of the bowl and floor, and as a matter of course this would also permit the escape of sewer-gas. To overcome this trouble, I have first constructed a short straight tubular metallic base adapted to be firmly secured to the floor; second, I have so constructed the foot of the bowl that it will be supported on the top surface of Said base. A pair of side clamps are caused to embrace the flanges of the foot of the bowl and projecting lip of the base, and as these clamps are of a 7o semicircular construction they will not fully embrace the circular construction of these parts. Therefore I have provided fillingpieces either of a U or V shape construction similar to the shape of the said clamps in cross-section, which filling-pieces are placed between the ears of said clamps and like said clamps embrace the lips of the base and foot of the bowl, thereby fully completing the circle, and thus effectually preventing leakage 8o between the meeting faces of the foot of the porcelain bowl and metallic base.

The construction and operation of my invention are as follows: I

l represents the bowl, which may be of any construction desired. 1L is the foot of said bowl, having a ange portion whose exterior lb is beveled for the purpose to be hereinafter more fully explained.

2 is the metallic base, consisting of a short straight tubular portion similar to a short section of piping and having the flange 2a, adapted to rest on the door 3 and to be firmly secured thereto by means of the screws 4. The

interior of said base (see Fig. 2) is provided with the inclined inwardly-projecting lip 2", to which is secured the soil-pipe 5 by means of solder 6. The upper portion of this base has the iiange 2, having the outer inclined face 2d to conform to the angular construction ofthe foot of the bowl. It also has the inwardly-projecting lip 2e to give a greater bearing-surface for the foot of the bowl. The upper surface of this base is provided with the corrugations 2f to more readily hold the packing-ring 7 in place.

8 and 9 are the side clamps, each of which is provided with the

ears

10 and 11, having holesl therethrough for the bolts 12. These clamps, Fig. 7, have an interior U or V shape surface adapted to conform to and embrace the flanges of the bowl and base.

13, Fig. 8, is a lead lining or other non-porous material adapted to readily conform to the interior surface of the clamps. It will be observed that a portion of the interior surface of these clamps is enlarged so as to form the shoulders 8a for the purpose of more effectually retaining the lining in place. When,

therefore, the lining is inserted, the inner sur-l face of the clamps will be a straight incline, so as to conform to the inclined surface lb and 2ll of the porcelain bowl and metal base, so that when the clamps are screwed up the pressure will by reason of these inclined surfaces tend to draw the foot of the bowl firmly against the flange of the base, and, bearing as they do on nearly the whole of the exterior surface of the foot of the bowl, there is no tendency to fracture the porcelain, as when the same is screwed to the door, as heretofore. Besides, the pressure of these clamps being inward toward the center of the bowl, there is no possible chance of the bowl shifting on its metallic support. It will be observed (see Figs. 2 and 9) that the bottoms of the U or V shape mouth of the clamps are made deep enough so that the apex will never come in contactwith the edges of the foot of the bowl or iiange of the base, so that all the pressure applied to the clamps isexerted against the beforementioned inclined sides. As the clamps adapted to embrace the foot. of the bowl and upper liange of the base must necessarily be of a semicircular construction and the said foot and base are liable to vary in size, it would be impossible to bring the ears of such clamps together and always be sure of exerting the required pressure, and thus maintain the bowl tirmly on the base and also prevent possible leakage between their meeting faces. To complete the circle, I employ two filling-

pieces

14 and 15, Fig. 3, one between each pair of ears. These filling -pieces are of course constructed exactly alike and (see also Fig. 5) have an angular mouthsimilar to that described for the clamps, and are adapted thereby to embrace the inclined faces of the foot of the bowl and upper flange of the base, each being provided with the lead lining 16. While'these filling-pieces are short, still they are made to conform to the same circular construction as theclamps. To hold these filling-pieces in place firmly against the flanges of the bowl and base, I have provided the recesses 17 in each ear of the clamps. The internal walls of these recesses conform to the outer shape or configuration of the filling pieces or blocks. p It will be observed (see Fig.V 6) that the sides of these filling-pieces are tapered to conform to the side walls 17, Fig. 10, of the recess, so that when the clamps are drawn together the side pressure will have a tendency to crowd the filling-piece against the before-mentioned flanges. The lead lining 1S covers the said side walls 17 and end walls 17h. In fact,the lining is shown as covering all of the interior walls of the recesses; but it is not absolutely necessary, except that the several bearing-surfaces are not apt to be so closely fitted but what a leak might occur, and the lead lining will more readily conform to any unevenness. When the side clamps are firmly brought together, they should also exert a pressure against the 'end walls of the filling-pieces as well, in order to insure a perfectly tight joint. If, therefore, the filling-pieces are not pinched firmly, lead or any other non-porous but compressible packing is placed between the ends of the filling-piece and the end wall 17LL of the recess in the ears of the clamps. 18, Figs'. 1, 3, and 1l, show such packing. By this arrangement every part of the circular construction of the foot of the bowl and iiange .portion of the base is fully covered, so that every avenue of escape for the water or gases is closed. In the event of having to inspect or repair the trap at any time all that is necessary is simply to disconnect the clamps and remove the bowl.

18h, Fig. 1, is a back air connection integral with the base 2. To provide for this, the base will have to be made deeper when a back air connection is desired than shown at Fig.` 2. In such casesthe base shown at Fig. 1 is used; otherwise the base shown at Fig. 2 may be employed.

The advantage to be derived from the abovedescribed construction is apparent to both the plumber and user. In the first place, the plumber can make a better joint, as he has no fear of breaking the porcelain bowl, as when it had to be screwed firmly to the floor, in order to make a common putty, cement, or rubber-gasket joint, and the user is beneiited in having a tight closet.

It will be understood that while Imake use of the word bowl7 and show a plain bowl, either porcelain or metal, provided with a foot adapted to rest on a separate base, it also applies to a combined bowl and trap. In fact, my invention is adapted to be applied to any form or construction of closetbowls, either porcelain or metal, as it is intended to do away with the necessity of tryloo` ing to make a'tight connection with the lead bend or soil-pipe at the floor or side wall, but instead to make such connection to prevent the escape of water or gas away from the said ioor or side wall.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. A bowl provided with an outwardly-cxtending flange upon its lower edge, a base provided with an outwardly-extending flange upon its upper edge, and an inwardly-extending flange upon its lower edge, and suitable clamps for connecting the base and the bowl, combined with a soil-pipe which extends into the base, and which has its upper edge expanded outwardly so as to catch over the inwardly-extending flange upon the bottom of the base, substantially as described.

2. The herein-described improvement in water-closets, consisting, in combination with a metal base adapted to support the bowl of a closet, said base and the foot of said bowl having flanges with correspondingly tapered or inclined surfaces, of semicircular side clamps adapted to embrace said flanges but not to meet each other, lling-pieces adapted to be placed between said clamps and also adapted to embrace such portion of said flanges not embraced by said clamps, recesses being provided in the ears of said clamps for said filling-pieces, for the purpose set forth.

3. In a water-closet of the class described, the combination of a short metal tubular supporting-base externally flanged at top and bottom and internally flanged at its bottom, an

independent soilpipe removably secured therein above said internal flange, and a bowl portion removably clamped thereon, the outlet of bowl and inlet of soil-pipe arranged in alinement with each other and with the tubular base and the upper end of the soil-pipe terminating at the interior wall of said tubular base, substantially as described.

4. In a water-closet of the class described, the combination of a short metal tubularsupporting-base externally lianged at top and bottom and internally flanged at its bottom, a soil-pipe detachably secured therein above said internal flange, a trap-bowl portion flanged at the bottom and supported on the upper flange of the tubular base in alinement with the axis of the base and soil-pipe, and semicircular clamps removably securing the base and bowl together, substantially as described.

5. The combination with a water-closet bowl having an outwardlyextending flatfaced llange at its lower end, of a tubular metallic support therefor having a horizontallyextended upper seat for the flange of the bowl and an internal annular flange to support a flanged upper end of a soil-pipe, and means for clamping the bowl and support together.
