WASHBASIN, BATH-TUB, 800.

I SPECIFICATION forming part of Letters Patent No. 503,249, dated August 15, 1893.

Application filed May 7, 1892. Renewed July 13, 1893- Serial No. 480,423. (No model-l To aZZ whom it may concern.-

Be it known that I, ARTHUR OBRIEN, a citizen 0f the United States, residing at Helena, in the county of Lewis and Clarke and State of Montana, have invented certain new and useful Improvements in Washbasins, Sinks, and the Like; and I do declare the following to be a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention has reference to improvements in wash bowls or basins, sinks and the like, and has for its object to provide means for ventilating the bowl and waste pipe, for utilizing the passage for the air of ventilation. to carry off the overflow, and means for securing the bowls of wash basins to the top slab in such a manner as that the points of connection will be concealed.

My invention consists of the construction, relative arrangement and operation of the parts constituting my improvements, all of which will be hereinafter fully and clearly described and specifically claimed.

In the accompanying drawings in which like letters of reference refer to like parts, Figure 1 represents in plan view, a wash basin with my improvements thereon, the top being removed. Fig.2, is a vertical central section of the same with the top in place; Fig. 3, a detail view of the bolt employed in connecting the bowl and top. Fig. 4, is a plan view of a sink embodying my improvements, and

' Fig. 5, is a vertical central section of the same.

Referring to the drawings, the letter A denotes the bowl of the basin or sink, which is formed with the usual waste outlet at. This bowl has formed integrally therewith a chamber b which extends a short distance to the rear and finds an outlet in passages formed in a coupling 0.

dis an overflow passage which communicates with the chamber 1) and with a line of pipe to the drain pipe or'sewer. To the rear of this overflow is an abutment e, which is of sufficient height to direct the water resulting from an overflow into the passage (1. The couplings has a vent fand an auxiliary over flow passage 9 which form a continuation of the chamber. In the event of the passage d, becoming clogged, or from other causes, the overflow should rise above the height of the abutment, the water will be carried off through the auxiliary passage, and through a separate line of pipe to the sewer. The foul air and vapors from the waste pipe and overflows find their way to the vent and from thence to a point outside of the building, and a thorough ventilation is established.

In Figs. 1, 2 and 3 I have shown improved means for connecting the bowl of a wash basin to the top slab, in such a manner as to conceal the points of connection. it represents a bolt having a T head h, and a dovetailed end h which latter enters a hole made therefor in the under side of the slab, and is held therein by means of solder. In the upper edge of the bowl I form a series of recesses'i, each of which conforms in size to the head of the bolt which it receives. Extending from the recess is an inverted T' shaped continuation which conforms to the shape of the head of the bolt. The bowl and slab are placed together with the heads of the bolts in the recesses i; the bowl is then moved slightly to the rear and the T heads enter the correspondingly shaped recesses j, and firmly lock the bowl and slab together. The construction of these parts permits of a connection being made without exposing to view any of the means employed, and hence a very neat job is the result.

Referring to Figs. 4 and 5, 7c is an opening arranged directly over the overflow passage 01 and Zis a plug for normally closing same. By removing the plug ready access is given to the said passage and pipe for the purpose of cleaning same and removing obstructions therefrom.

In the construction shown in Figs. 1 and 2 the inner line of the topof the bowl is carried back to a point in line with therear wall of the overflow passage (1, and hence no plug is necessary. .I may however close this passage by the top slab, and in such case an opening of the abutment, and an air vent above said in the latter with a closing plug may be emauxiliary overflow communicating therewith ployed. and with the chamber, all substantially as I claim and for the purposes set forth. 5 In Wash basins, sinks and the like, the com- In testimony whereof I aifix my signature in x 5 I bination with a bowl formed with a Waste outpresence of two witnesses.
