ATTO R N EY BOWL SLEEVE GASKET Paul E. Thies, Columbus, Nehr.

Application December 3, 1953, Serial No. 395,890

2 Claims. (Cl. 288- 20) This invention relates to household plumbing fixtures and particularly toilet bowl installations, and in particular a sealing gasket adapted to be positioned around the outlet opening of a toilet bowl and between the base of the bowl and a lead nipple or the like extended from soil pipe below through the floo-r whereby seepage through the connection or moisture resulting from capillary attraction is substantially eliminated.

The purpose of this invention is to prevent dampness in floor areas around toilet bowls and thereby eliminate rotting or decaying of wood and other flooring materials around toilet bowls.

The connection between a toilet bowl and soil pipe below a floor upon which the bowl is positioned is made by a plumber leaving an open lead nipple extending upwardly from the bell of the last section of the cast iron soil pipe to an elevating flush with or slightly above the surface of the floor, and after the finished floor is in place the toilet bowl is set over the nipple with the connection sealed by a ring gasket of wax, putty, rubber, or other suitable material. In some instances the nipple is flanged and in others the bowl is provided with a short neck that extends downwardly into the upper end of the nipple. Connections of this type are satisfactory when new and usually last a number of years, however, with settling of the building and shrinking in the building materials the connection opens slightly and the sewage liquids leak through causing the surrounding parts of the floor to decay.

With this thought in mind this invention contemplates a ring gasket of wax, sponge rubber, or other similar material, and a depending sleeve or skirt, the diameter of the lower end of which is less than that of the upper end, extended downwardly from the inner surface of the ring and having a flange on the upper end extended into the material of the ring.

The object of this invention is, therefore, to provide a sealing gasket adapted to be positioned between the outlet opening of a toilet bowl and a nipple extended upwardly from soil pipe whereby the possibility of leakage between the parts is reduced to a minimum.

Another object of the invention is to provide a sealing gasket for toilet bowls that carries the liquids downwardly into the nipple extended from the soil pipe.

Another important object of the invention is to provide an improved gasket for sealing the connection between a toilet bowl and a drain or soil pipe below the bowl in which the gasket is adapted to be installed by the average artisan.

A further object of the invention is to provide a gasket for sealing the connection between the outlet opening of a toilet bowl and soil pipe below the bowl in which a flange on the upper end of a funnel-like ferrule is embedded in a ring gasket o-f pliable material whereby with the ring gasket nested between the under surface of the bowl and a flange on the upper end of a nipple and the ferrule extended downwardly into the nipple the possibility of nited States Patent ice moisture crawling upwardly through the connection by capillary attraction is substantially eliminated.

A still further object of the invention is to provide an improved sealing gasket for connections between toilet bowls and drain or soil pipes in which the gasket is of a simple and economical construction.

With these and other objects and advantages in view the invention embodies a ring of gasket material having a continuous annular slot in the inner surface and a sleeve having an outwardly extended flange on the upper end and a contracted portion on the lower end positioned with the flange in the slot of the ring and with the contracted portion depending from the ring.

Other features and advantages of the invention will appear from the following description taken in connection with the drawings, wherein:

Figure l is a side elevational view of the improved sealing gasket with part broken away and with one side shown in section.

Figure 2 is a side elevational view of a typical toilet bowl with part of the bowl broken away and part shown in section and also showing the application of the improved gasket of this invention to the connection between the bowl and the nipple of soil pipe, the gasket being shown on a reduced scale from that shown in Figure 1.

Figure 3 is a plan view of the gasket with all other parts omitted.

While one embodiment of the invention is illustrated in the above referred to drawings, it is to be understood that they are merely for the purpose of illustration and that various changes in the construction may be resorted to in the course of manufacture in order that the invention may be utilized to the best advantage according to circumstances which may arise, without in any way departing from the spirit and intention of the device, which is to be limited only in accordance with the appended claims. And while there is stated the primary field of utility of the invention, it remains obvious that it may be employed in any other capacity wherein it may be found applicable.

In the accompanying drawings, and in the following specification the same reference characters are used to designate the same parts and elements throughout, and in which the numeral 8 refers to the invention in its entirety, numeral 10 the ring or gasket of wax, sponge rubher, or other suitable material, numeral 12 the upper portion of the funnel or sleeve, numeral 14 a flange extended from the upper edge of the sleeve and positioned in a slot 16 in the inner surface of the ring 10, and numeral 18 the depending lower portion of the sleeve.

The upper inner edge of the ring 10 is provided with an arcuate surface 20 that is formed to nest in a fillet around a neck 22 extended downwardly from a lower panel 24 of the toilet bowl 26, as shown in Figure 2, and the intermediate portion of the sleeve is provided with an inwardly otfset section 28 whereby the lower portion or skirt of the sleeve is spaced from the inner surface 30 of a lead ferrule, as indicated by the numeral 32.

The upper end of the lead ferrule or nipple is provided with an outwardly extended annular flange 34 upon which the ring is positioned, and when the toilet bowl is in position the ring 10 is squeezed or clamped between the flange 34 and panel 24 of the bowl.

As illustrated in Figure 2, the flange 34 of the lead ferrule is positioned on a floor, as indicated by the numeral 36, and it will be understood that the upper end of the lead ferrule or nipple from the soil pipe may stop at any suitable elevation.

With the diameter of the skirt or depending lower portion 13 of the sleeve less than that of the inside diameter of the lead ferrule or nipple the possibility of water creeping upwardly through the connection is substantially eliminated.

With the parts arranged and assembled in this manner a water and gas tight seal is provided and with the ring 16 positioned upon the flange 34 of the lead nipple or ferrule and the toilet bowl set upon the ring the ring is in sealing engagement with both the flange and lower surface of the bowl whereby either water or gas will not leak through the joint, and with the skirt 18 extended downwardly into the ferrule 32 it will provide a guide carrying the fluids downwardly beyond the connection between the toilet bowl and fitting of the soil pipe below. The upper end of the ferrule 32 should be positioned so that when the toilet bowl is adjusted to the permanent position the gasket will be compressed with both surfaces in positive contact with the adjoining parts.

By this means a sealed joint is provided that will remain sealed indefinitely.

From the foregoing specification it Will become apparent that the invention disclosed will adequately accomplish the functions for which it has been designed and in an economical manner and that its simplicity, accuracy, and ease of operation are such as to provide a relatively inexpensive device, considering what it will accomplish, and that it will find an important place in the art to which it appertains when once placed on the market.

It is thought that persons skilled in the art to which the invention relates will be able to obtain a clear understanding of the invention after considering the description in connection with the drawings. Therefore, a more lengthy description is regarded as unnecessary.

Changes in shape, size, and arrangement of details and parts such as come within the purview of the invention claimed may be resorted to in actual practice, if desired.

Having now described the invention that which is claimed to be new and desired to be procured by Letters Patent, is:

1. In a sealing gasket for a toilet bowl, the combination which comprises a ring of pliable material, said ring being rectangular-shaped in cross section and having an annular slot in the inner surface, a sleeve positioned with the upper part nested against the inner surface of the ring and having an inwardly offset lower part providing a skirt, the diameter of which is less than that of the upper part, and a flange extended from the upper end of the sleeve and positioned in the slot of the ring.

2. In a gasket for sealing the connection between a toilet bowl and soil pipe below the bowl, the combination which comprises a ring, rectangular shaped in cross section and having an annular slot extended from the inner surface into the body of the ring, the slot being positioned substantially midway of the height of the ring and the upper inner edge of the ring above the slot being relieved providing an arcuate surface, and a sleeve positioned with the upper part nested against the inner surface of the ring and with an annular flange extended from the upper end embedded in the slot of the ring, said sleeve having an inwardly offset section spaced below the ring providing 21 depending skirt, the diameter of which is less than that of the upper part of the sleeve whereby with the sleeve positioned in a tube with the ring on the upper end of the tube, the skirt is spaced from the wall of the tube.
