Specification of Letters Patent.

Patented Oct. 1, 1912.

Application filed January 14, 1911, Serial No. 602,676. Renewed July 18, 1912. Serial No. 710,287.

To all whom it may concern:

Be it known that I, HENRY M. WEAVER, of lvlansiield, in the county of Richland and State of Ohio, have invented certain new and useful Improvements in Lavatories; 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.

This invention relatesto improvements in lavatories and more particularly to improved outlet devices therefor,-the object of my present invention being to construct the outlet devices in such manner that the metal bearing for the plug, at the upper end of the waste coupling, shall be so disposed as to be below the bottom surface of the lavatory, whereby those metal parts at the bottom of the lavatory which are liable to tarnish or become discolored, will be hidden from view.

With this object in view, the invention consists in certain novel features of construction and combinations of parts as hereinafter set forth and pointed out in the claim.

In the accompanying drawings, Figure 1 is a sectional view of a portion of a bowl and showing an embodiment of my invention, and Fig. 2 is a similar view showing a modified construction.

1 represents a bowl or lavatory, preferably porcelain lined, and provided with a waste outlet 2 and with an overflow duct 3. A portion of the wall of the waste outlet 2 is made vertical and the lower portion of said outlet is somewhat contracted in size and the wall of this contracted portion of the outlet opening in the bowl is shaped to form an annular shoulder 4, which, as shown in Fig. 1 may be beveled, but I prefer to provide a square shoulder P as shown in Fig. 2. The upper end of a waste-pipe member 5 is disposed within the outlet opening 2 and provided with ports 6 communicating with the overflow duct 3. The upper end of the pipe member 5 is made flaring and terminates an appreciable distance below the upper end of the waste outlet and the bottom surface of the interior of the bowl. The exterior of the flaring portion of the pipe member 5 form a beveled shoulder 7 to rest on the beveled shoulder 4: in the bottom of the outlet opening 2 and a portion of the outer face of the flaring end of the .pipe member is made vertical so as to lie against a part of the vertical wall of the;outlet opening 2. In the construction shown in Fig. 2, the pipe 5 is made with a square shoulder 7 (instead of the beveled shoulder 7 shown in Fig. 1) to rest upon the square shoulder. 1. The inner face of the flaring upper end of the pipe member constitutes a seat 8 for the metal bearing face 9 of a plug 10. The pipe member 5 passes freely through an opening 11 in the bottom of the bowl below the overflow duct and is threaded externally for the reception of a nut 12 which bears against the under surface of the bowl. It is apparent that by screwing this nut home, the upper portion of the pipe member will be drawn down so as to cause the shoulder 7 or 7 to bear firmly upon the seat or shoulder 4 or 4P near the bottom of the outlet opening 2 of the bowl. The plug 10 may be provided with a porcelain cap 13 as shown in Fig. 1 and when said plug is upon its seat, the top of the porcelain cap will be approximately flush with the bottom of the bowls interior,--or the metal plug can be extended upward so as to come flush with the bowls interior surface, as shown in Fig. 2. The plug is provided with a shank 14 provided with strainer lugs 15, and with this shank, a stem 16 can be connected and provided with lugs. Or the plug shank and stem with strainers can be made in one piece. The stem 16 may be connected with any suitable plug-operating mechanism.

From the construction and arrangement of parts above described, it will be apparent that the metal bearing for the plug is located in the waste outlet an appreciable distance below the bottom surface of the interior of the bowl and will be hidden from view by the plug.

It has heretofore been the custom to provide the upper end of the waste pipe member with an annular flange located in the bottom surface of the bowl and affording a seat for the plug. This exposed metal part in the bottom of the bowl is liable to tarnish or to become discolored and present an untidy appearance. By locating the plug bearing below the upper end of the outlet opening and below the bottom surface of the interior of the bowl, said metal hearing will be hidden from view at all times by the plug, even when the latter is raised, and the bottom of the interior of the bowl will be freed from metal parts which are liable to become tarnished or discolored.

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

The combination with a lavatory having a waste outlet provided with an annular bearing below its upper end, and a waste pipe having an annular bearing which seats upon and is supported by the annular bearing in the waste outlet, said waste pipe being provided at its upper end with a valve seat which is located below the upper end of the waste outlet, of a plug valve adapted face of the lavatory, substantially as set forth.

In testimony whereof, I have signed this specification in the presence of two subscribing witnesses.

HENRY M. WEAVER.
