LAVATORY WITH BUILT-IN WATER HEATER 2 Sheets-Sheet 2 United States Patent O Mce 3,065,473 LAVATRY WTH BUILT-JN WATER HEATER Claus L. Sporck and William Harry Busch, Cincinnati,

hio, assignors to The Lodge & Shipley Company, Cincinnati, hio, a corporation of Ohio Filed .lane 29, 1961, Ser. No. 129,741 s Claims. (ci. 4-166) This invention relates to lavatories of the type which incorporate means for heating the water that is supplied to'them. Thus, these lavatories are employed in places where a supply of cold water only is available, for example, in a filling station, or in places where it is desired to have an immediate supply of hot water at the tap, for example, in a bathroom which is remotely located with respect to a household water heater.

One of the objectives of this invention is to provide a lavatory of the type set forth which is simpler in construction, more compact and less expensive to manufacture and to install than those which have been available in the past. Toward this end, the lavatory of this invention comprises essentially a bowl and a tank which are the same general shape so that the bowl nests within the tank. In this way, the tank takes up a minimum amount of space. Furthermore, the tank, being essentially the same shape as the bowl, although slightly larger in diameter, is adapted to be fabricated utilizing the same manufacturing techniques utilized for the bowl.

Another objective of the invention has been to provide a lavatory of the type set forth in which the tank is easily removed and replaced, in the event repairs are required.

Other objectives of the invention will be readily apparent to those skilled in the art from the following detailed description of the drawings, in which:

FIGURE l is a cross sectional view taken on a plane which passes vertically through the center of the lavatory of this invention.

FIGURE 2 is an enlarged fragmentary cross sectional view illustrating a detail of the construction of the central area of the bowl at an edge of the drain opening.

FIGURE 3 is an enlarged fragmentary cross sectional view illustrating a detail of means for securing the tank to the underside of the deck ofthe lavatory.

FIGURE 4 is a diagrammatic View illustrating the flow of water from a cold water supply line through hot and cold valves, the tank and the aucet spout.

FIGURE 5 is a perspective view looking down into the tank of this invention.

FIGURE 6 is a top plan view of a lavatory made in accordance with the principles of the present invention.

The lavatory shown in the drawings comprises a bowl, indicated generally by the numeral 10, and a tank, indicated generally by the numeral 11. It is preferred that the bowl, including a deck portion indicated generally by the numeral 12, and the tank be fabricated of stainless steel, utilizing metal forming techniques such as one known by the trade mark Floturn. Thus, the bowl is symmetrical with respect to a vertical axis passing through its center, being in the shape of a frustum of a cone to provide a slanting side wall 13 and a substantially flat bottom wall 14. Preferably the deck in the annular area thereof immediately surrounding the bowl is conifurated to provide a raised bead 15 which is circular and which is provided to strengthen the deck. As shown in FIGURE 6, the deck may be substantially rectangular and a continuation of the upper surface thereof may be turned up at the rear to provide a splash panel 16. Additionally, a skirt 17 may be turned down from three of the outer edges of the deck at the sides and front thereof. As shown, a radius is provided at each place where a bend 3,055,473 Patented Nov. 27, 1962 is made in the metal forming the bowling and deck to avoid sharp corners.

A drain opening 18 is provided in the center of the bottom wall of the bowl and a drain sleeve 19 depends through this opening. As shown, an annular flange 20 at the uper end of the drain sleeve tapers outwardly to a feather edge and then the area of the bottom wall 14 immediately surrounding drain opening 18 upon which this flange rests is angulated downwardly to compensate for the taper.

The tank is formed from two Stainless steel shells, both of which are essentially in the shape of a frustum of a cone but of large diameter than the bowl. The inner one of these two shells is conligurated to provide a radial upper flange 21, side wall 2.2 and a bottom wall 23. The bottom wall 23 has a central opening in it as shown at 24 which is identical in size to the drain opening 18 formed in the bottom wall 14 of the bowl. The outer one of the two sheet metal shells includes an annular llange 25, a side wall 26, a bottom wall 27, an angulated inner wall 28 and an inner radial flange 29. The latter flange also has a circular opening in it, as shown at 30, which is identical in size to the drain opening 13 in the bowl.

In the assembly of the tank, the two upper flanges 21 and 25 may be fastened together by means such as adhesives. The same thing may be done with respect to the inner flange 29 of the outer shell of the tank, where it rests against the bottom wall 23 of the inner shell surrounding the circular opening 24 therein. The drain sleeve 19 has external threads 31 upon it which are designed to receive a lock nut 32. Thus, when the tank is slipped up on the drain sleeve and the lock nut 32 turned up on the external threads 31, the center section of the tank is pressed upwardly. A large washer, as the one shown at 33, may be employed between the lock nut and the inner flange 29 of the outer shell. Also packing such as that shown at 34 may be interposed between the tank and the undersurface of the bottom wall 14 of the bowl surrounding the drain sleeve.

The outer edges of the tank may be secured to the underside of the deck of the bowl by means such as headless bolts which may be secured to the undersurface of the deck by means such as adhesives. The threaded Shanks of these bolts extend through matching holes in the flanges 2.1 and 25 of the two shells of the tank and then a nut such as the one shown at 3S threaded onto the exposed end of the bolt. A gasket 36 may be interposed between the deck part of the sink and the flange 21 of the inner shell of the tank. It is preferred that insulation as shown at 3'7 be employed to fill the space between the bowl and the tank in order to reduce heat loss.

An electrical heater 33 is employed to heat the water. As shown, this electrical heater may be in the form of a doughnut and installed in the bottom of the tank in the urea thereof surrounding the inner wall 23 of the outer shell. If desired, the heater may be mounted outside of the tank. Electrical leads 39 may pass through the wall 28 as shown at FIGURE l. No details of this heater are shown here inasmuch as it is believed to be well within the expected skill of those acquainted with the art in order to devise an adequate circuit and the proper thermostatic controls in order to maintain the supply of water in the tank at some predetermined temperature level.

In making an installation, it is necessary only that a cold water pipe such as the one shown at ill in FIGURE 4 be extended to `the site of the installation. This supply line may be split at a T 41 into one line 42 which goes to a cold water faucet 43, and another line 44 which goes to la hot water faucet 45. A line 46 may lead from the hot water faucet into the bottom of tank 11 and then another line 47 may lead from the top of the tank to a faucet spout 4S. The -two faucets of the spout may be of conventional constructio-n, although it is preferred that the spout overhang the bowl substantially, because most of the utility of a lavatory of this type is in the washing of ones hands. As shown in FIGURE 1, it is preferred that the pipe 46 be iitted with-ahw insidethe `tank so that the flow of water is directed tangentially with respect to the wall of the outer shell.

In the operation of the-lavatory, when the cold water faucet is turned on theflow-is from the cold water supply linethrough line 42 and faucet 43 directly vto the spout 48. On the other hand,when the hot water faucet is turned on, the -tlow is through line 44 and faucet 45, linto the bottom of tank kllfll and then out of the top of the tank through line `47 to the faucet spout 48. In this way, the hot water being withdrawn from the top of the tank is actually Vbeing pushed out of'the tank by the cold water entering the bottom. Thisfmeans, of course, that thereis a limited supply ofl hot water, depending upon the capacity ofthe-tank, but this is believed tobe noparticular detriment inasmuch as there is some mixing of the water in the tank and the -tankhas suflicient lcapacity for washing several persons hands. One advantage to the arrangement shown is Ithat at no time is the tank subjected to the pressure-ofthe water supply line 40. Thus, it is not necessary to'make this'tank ofheavy metal, noris it necessary to provide elaborate sealing or fastening devicesy for the mating edges of the two shells making up thetank.
