JOHN CLIFFORD, 'OF CHICAGO, ILLINOIS, ASSIGNOR TO L. WOLFF I IANUFACTUBING COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS.

Specification of Letters Patent.

Patented Oct. 22, 1912.

Application filed June 14, 1906. Serial No. 321,608. i

To all whom it may concern? Be it known that I, JOHN CLIFFORD, a citizen of the United States, residing in Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Waste or Soil Pipe Connections for Water-Closets, of which the following is a specification.

My invention relates to improvements in waste or soil pipe connections for water closets at the floor or base of the .closet by which the customary four inch lead bend which connects with the soil pipe is connected to the outlet of the water closet.

Heretofore, although sanitarians and experts interested in the installation of plumbing fixtures have long recognized that the connection of the 'water closet with the soil pipe or sewerage system at the floor or base of the closet is a matter of great importance in a sanitary sense, as a faulty connection here leaves an exit for sewer gases in the living rooms, and although many attempts have heretofore been made to provide a connection that would be sanitary, and at the same time meet or fulfil the other necessary requirements, or conditions, the means heretofore in use for connecting the closet with the soil pipe have been open to serious objections. One ordinary method of making this connection at the floor of the lead bend with the outlet of the closet is to flange the upper end of the lead bend over on the floor, then put a roll of putty on top of this flange, then place the closet on and secure it down by wood screws extending through the base of the closet and entering the floor; but in this form of connection, the putty in time dries out and cracks and gives a leak or outlet to objectionable sewer gases.

Though this form of connection is largely used, it is condemned by all acquainted with the requirements necessary to make a proper and sanitary joint. Another common ractice is the use of a circular brass floor ange or clamping ring having a flat upper face through which the upper end of the lead bend is inserted and soldered at the inner edge or surface of the ring, this edge or surface being beveled off for the accommodation of the solder and to facilitate the soldering operation, and a flat rubber gasket being interposed between the flat upper surface of the clamping ring and the base of the closet and compressed by the bolts which connect the clamping ring with the closet base. In this construction, the base of the closet is countersunk around the spud or outlet to accommodate the thickness of the brass clamping ring and the rubber gasket. This construction, however, is very-K unsatisfactory and defective and is condemned by all sa/nitarians, as the rubber gasket or packing in time gets hard and shrinks from its contact with the closet and clamping ring and cracks open or disintegrates so that it affords little protection against leakage or inlet of gases.

The object of my invention is to provide a sanitary, practicable, economical and eflicient connection between the water closet and the lead pipe bend leading to the soil pipe orsewerage system, capable of bein easily and conveniently set up or applied without special knowledge or skill, which 7 will have provision for inequalities in the earthenware base of the closet due to warping or other causes, and also provision for accommodating inequalities in the floor or other causes preventing the leveling of the brass floor flange or clamping ring, so that the connection may automatically adjust itself to existing conditions, which will permit the base of the closet to be brought to a practical rest upon the surface of the floor which will relieve the base .of the closet from any breaking of destructive strains incident to screwing or attaching the base of the closet to the floor, and in which also the packing interposed between the floor flange or clamping ring and the base of the closet will also have the required or desirable body or thickness throughout every point of its circumference necessary to the production and maintenance of a tight or perfect and sanitary joint.

My invention consists in the means I employ to practically accomplish this object or result. That is to say, it consist in connec-- tion with a closet havin the customary horizontal base surrounding the spud or outlet, and furnished on its under side with .an annular recess or channel to receive a brass or metallic flange or clamping ring and the packing interposed between the base and clamping ring, of an annular clamping ring adapted .to be bolted to the base of the closet and provided on its upper face with an annular groove to receive a thick and compressible packing ring, the clamp ng ring having an inner, vertical or c lindrlcal surface to receive the lead ben and .to which the lead bend is soldered, the inner surface of the clampin ring being preferably rounded or bevele at its upper corner to facilitate the entry of the solder and the soldering operation, and a thick, compres- 1 sible packing ring, preferably about one half inch in thickness or cross sectional diameter, adapted to fit in the packing seat or annular groove in the upper face of the clamping ring, and to be compressed between the. clamping ring and the base of the closet, said packing ring by its thickness and compressibility not only accommodating or providing for inequalities in or warp ngs of the closet base, variations 1n level of the clamping ring, but also enabling the base of the closet to be brought to a practical rest against the upper surface of the floor, and also maintaining at all points of the circumference of the packing ring a suflicient thickness or body to prevent all possibility of the packing ring becoming defective at any point for want of suflicient thickness or body to effect a proper and sanitary joint.

My invention also consists in the novel construction of parts and devices and in the novel combinations of parts and devices herein shown and described.

In the accompanying drawing forming a part of this specification, Figure 1 is a central, vertical section of a water closet floor connection embodying my invention.

I Fig. 2 is a longitudinal, detail, central, vertical section showing the connection between the base of the closet and the lead bend which leads to the soil pipeor sewerage system. Fig. 3 is a top or plan view of the brass flange or clamping ring and Fig. 4 is a detail vertical sectional view showing the packing ring and cooperating parts before the packing is compressed by screwing down the clamp bolts which connect the closet with the clamping ring. Fig. 5 is a detail section of the packing ring.

In the drawing, A represents a portion of the floor or base upon which the closet is mounted.

B is the closet having the customary base or horizontal flange B and spud or outlet b. The closet base B is provided on its under side with an annular channel or recess 6 insane? .ners, the parts have interengaging shoulders to keep them in pro er relation to each 'other during the sol eri ng operation, or

while the solder is setting. The clamping ring D is also provided with an annular groove or recess d forming a seat for the packing. The outer annular wall or flange d of the packing groove or seat 01 serves to confine the packing and prevent' its s reading laterally. The clamping ring also has a horizontal flange or rim d furnished with curved slots d to receive the clamping bolts E, the slots being beveled or countersunk so that the heads of the bolts may fit flush with or within the lower face of the rim d of the clamping ring. The clampin ring D also is furnished with holes (1 an countersinks d to receive the screws by which the clamping ring is attached to the floor or base A.

E are the nuts of the clamping bolts E, suitable washers E being interposed between the nuts and the closet base.

F is a thick, soft, flexible, compressible packing ring, preferably about one half inch in cross sectional diameter, and preferably composed of asbestos with a mixture of white lead to provide an adherent cohesive bond, and incased in asbestos cloth f, fitting in the annular groove or packing seat 07 of the clamping ring D so that when pressure is brought to bear on this packing ring, it fills out the space designed for it by the groove d in the clamping ring D and accommodates itself to any inequalities or warpings in the closet base or to any variations from the true level in the clamping ring or other inequalities and at the same time maintains a suificient thickness or body at all points of its circumference to effect a tight, perfect and sanitary joint or connection between the lead bend and the closet bowl.

The adjustability of my compensatable packing in its limited seat or confining groove formed by the outer wall of the annular groove or recess d in the clamping ring D on the one side, and exterior wall of the closet spud b on the other side, permits the floor engaging or bearing base B of the closet B to be drawn down properly against the floor so-that it can be secured thereto in the usual manner, and to compensate for any irregularities due to the warping of the closet base B in firing, variations in the depth of the annular recess in the closet base B variations in the height or level of the clamping ring D when soldered on the lead bend C or sewer connection, &c., while at' the same time efiecting a sewer-tight connection between the closet base and clamping ring.

I claim The combination with a water closet bowl 5 having a floor engaging base provided with an annular recess, and a flat horizontal clamp face, of a lead soil pipe, a floor plate having a vertical cylindrical inner surface with beveled upper corner, said floor late 10 receiving the lead soil pipe and sol ered thereto, and having on its upper face an annular groove with flat horizontal bottom, a

thick, soft, flexible packing ring of compressible material fitting in said annular groove and engaging the closet base, and clamp bolts extending between said closet base and floor plate and compressing said packingring vertically between said horizontal clamp faces of said closet base and floor plate.
