Description

Patented Apr. 30, 1935 nutren stares PATENT perles 3 Claims.

This invention relates to plumbing xtures and in particular to the arrangement of the water supply thereof in relation to the water retaining compartment and overow chamber.

In plumbing xtures the water supply pipe is generally located over and toward the rear of the water retaining compartment. When the wat/er supply is shut ofi", water remaining in and near the end of the supply pipe drips into the water retaining compartment. Water also drips from the supply pipe into the Water retaining compartment of plumbing fixtures because of leaky valves in the supply lines.

The ldripping of water into the water retain- 5 ing compartment of plumbing fixtures is generally undesirable for two major reasons. First, the constant drip, drip, drip creates an undesirable sound which annoys people in the room, in rooms adjacent to, or within hearing of the if' room in which the plumbing fixture is located.

Second, in communities in which the domestic water supply contains iron and the like, the dripping of water into the Water retaining compartment of plumbing xtures causes localized and unsightly stains on the enamel in regions directly under the water supply pipe. Also, in some fixtures, hard Water from leaky valves runs from the supply down one side of the Water retaining compartment thereof and causes unsightly streaky stains thereon.

The main object of this invention is to provide a drip proof plumbing fixture.

Another object of this invention is to provide a plumbing xture having a water supply in connection therewith which is so located as to direct water under pressure being discharged therefrom into the water retaining compartment oi the said fixture and to permit water dripping from said water supply to run down the inside of an overflow chamber.

Another object of this invention is to provide a plumbing fixture having a water retaining compartment and an overflow chamber in combination with a water supply concealed from View in a communicating overflow aperture between the said water retaining compartment and the overiiow chamber, the said water supply being so located as to direct water under pressure being discharged therefrom into the water retaining compartment of the said fixture, the wall of the Water retaining compartment directly below the overow aperture being so formed as to direct Water dripping from the said Water supply into the inside of the said overflow chamber.

Yshowing a lavatory embodying this invention.

This invention may be applied to other lavatory constructions known to those familiar with or skilled in the art, and may be readily applied to bath tubs, foot baths, kitchen sinks,

laun tubs and the like; such use and applij;

cation of this invention is intended to be broadlv within the scope hereof.

Referring particularly to the drawing, the embodiment sho-wn therein comprises a lavatory ill having preferably integral vertical back splash shield il at the top of which the horizontally disposed top portion i2 and at the sides of which the extended vertical sidesr iS retain the lavatory and splash shield at the desired distance from the wall il and at the same time enclose the rough piping from view. The top portion i2 is turned down at its rear side to form a vertically disposed .strip i5 by which the lavatory is supported from the Wall lli by any suitable means such as the clips il and lag screws ill. The extended vertical sides i3 are preferably turned in to form a bearing strip l along the wall ill.

The lavatory is provided with a water retaining compartment li! having an overflow aperture Eil formed in the rear thereof at the proper height to permit water, after attaining a predetermined depth in the water retaining compartment, to overflow into an overflow chamber 2|. A drain 2?. is located at the bottom of the Water retaining compartment and may be closed by any desired type of stopper or stopping mechanism, not shown. Both the overflow chamber 2l and the drain 22 are preferably connected to a trap, not shown, through which surplus water and waste from the lavatory pass before entering a soil pipe which preferably carries the said Water to a sanitary sewage system.

in forming the overflow aperture 2li, a lip 23 is preferably turned backward from the rear of the water retaining compartment I9 tolap over the forward wall of the overflow chamber 2l. A shield 25 is formed in front of and over the said overflow aperture 2t to conceal it from View.

The rough hot and cold water pipes 25 and 26 lead to two valves 21 having operating handles 28 by means of which water is admitted and mixed in the desired quantity and to the required temperature in supply pipe 29 from whence it is discharged under pressure into the water retaining compartment i9.

The supply pipe may be held in its proper location in respect to the overow aperture 2G, the lip 23 and the shield 2d by such means as a washer 39 and a nut Si and a washer 32 and a nut 33 of each valve 2? which engage the splash shield l i, proper holes having been formed in the said splash shield ll through which the stem ends of the valves 2 protrude.

The end of the supply pipe 29 is so shaped and located in respect to the overflow aperture 20 and the lip 23 that water supplied under pressure through the supply pipe 29 will discharge into the water retaining compartment I9 and water dripping from the said supply pipe 29 will drip into the overflow chamber 2l preferably via the rearward end of the lip 23 and down'the inside of the forward wall of the overilow chamber 2l.

The overflow chamber 2| may be three sided or semi-circular in shape and welded to the black of the rear of the water retaining compartment, or may be cast integral therewith, in which event the end of the lip '.23 would be brought around to substantially meet the back of the rear wall of the water retaining compartment which would serve as one wall of the overflow chamber. It is important to prevent dripping within the overow compartment which may be and is accomplished by the proper shape of the lip 23 in respect to the inside wall of the overflow chamber 2l.

Although only one form land embodiment of this invention has been disclosed and described in detail, it will be apparent tothose skilled in the art that various details thereof may be changed and many modifications made without departing from the scope of the appended claims.

I claim:

l. In combination with a plumbing xture comprising a water retaining compartment and an overow chamber having a communicating overflow aperture therebetween, a supply pipe having its discharge end so shaped and located in respect to said overow aperture that water supplied under pressure through said supply pipe will discharge into said water retaining compartment and water dripping from said supply pipe will drip into said overflow chamber.

2. In a plumbing fixture, a water retaining compartment, an overflow chamber adjacent to :said water retaining compartment, the said water retainingcompartment having an overflow aperture formed in a Wall thereof, a curved lip formed in said wall directly below said overflow aperture, the end or said curved lip being in juxtaposition to the inside wall of said overflow chamber, and a supply pipe having its discharge end so shaped and located in respect to said overflow aperture and curved lip that water supplied under pressure through said supply pipe will discharge into said water retaining compartment and water dripping from said supply pipe will drip on said curved lip and flow down the inside wall of the said overflow chamber.

3. in combination, a plumbing fixture having a water retaining compartment and an overflow chamber adjacent thereto, the said water retaining compartment having overflow aperture formed therein, a supply pipe having its discharge so shaped and located in the respect to said overflow aperture that water supplied under pressure through said supply pipe will discharge into said water retaining compartment and water dripping from said supply pipe will drip into said overow chamber, and means for directing water dripping from said supply pipe into the overflow chamber and down one Wall of said overflow chamber.
