Y ATTACHMENT Eon- PLUMBING FIXTURES.

vApplication mea January 26,1924. serial No. 638,748.

To all whom t 'in/ary concer/ft:

Be it known that I, CHARLES HERMANN WAEorI'rEma citizen ofV the United States, residing in New York, county of New York,

and State of New York, have invented cerfixture, which will provide 4means for controlling the rate of'ldischarge and the heighty of water within the fixture while effectually preventing air suction and vortices primarily the causev of the discharge noises particularly objectionable in dwellings.

It is my particular object to provide an attachment forv the verflows Vof'bath tubs permitting the user to control theV overflow level therenand enjoy the'benets ofsuoh water level as may best suit his convenience and physique while assuring thatthejoutowing liquid discharge will be silent and of minimum quantity Vfor ythe maintenance of solutions of constant density when bathing preparations are employed.

Certain other improvements accomplished V by my invention will be apparent from the following description. of one embodiment thereof. d Y

Like numerals have been employed to indicate like parts throughout the several views. In the drawings- Figure 1 is a front elevation of a pre ferred embodiment of my invention,

Figure 2 is a cross section of Figure 1, taken upon line 2-2,

Figure 3 illustrates an application of my 'f invention to a standard bath tub and shows the device of Figure 1 crossesectioned in vertical plane as upon 1ine.3-3.

VReferring particularly to Figures l and gular in outline, the edge 14V supplying a Weir for the discharging Vwater as will be described. Sides 9 and the end 10 are preferably provided at their edges with an insert of packing material l5, for water-tight abutment against the interior surface ofthe bathtub in such manner that this surface forms lthe fourth side of the box as shown in Figurev 3. d Y

The interior surfaces of bath tubs are usually of porcelain like smoothness andofk extreme hardness, and drilling the fixture without chipping this surface in a destructive manner is practically impossible. Engagement of the other fittings of the tub, such as faucets 20, to retainv an attachment involves `ungainly. structures not universally adaptable to all installations.

Attachment of mydevice is secured withoutthe foregoing difficulties by the employment ofr vacuum cups 22, preferably of rubber. bar 24bysuch means as the studs 26. This cross bar 24 is provided with openings slid- Cups 22 are secured to a cross eenk ably engaging the studs 28 which are atf tached to the back'7 of box member 5.v For adjustment of the relation between the vacuu-m cups and the member 5, and tocompress packing 15 fory the formation of a water-tight joint with the tub surface, a thumb screw 30 is threaded into the bar 24 and bears upon back 7.

In use the cups 22 are moistened and then pressed against the inner surface 32 excluding the air from the spaces 34. The pressure of the surrounding atmosphere then holds the cups to the tub surface. Thus to apply the device to a bath tub the user merely places it over the waste opening 35 of the bath tub andpresses the cross bar 24 causing the suction cups 22 to grip the tub surface.` yHe then turns thumbscrew 30 until it bears on back 7 and thus compressesy the packing 15. The device is now in working position.v It will be understood that the tub may be engaged at any height with reference to the waste opening 35 and that the water level in the tub will be controlled by the height of edge 14, as all discharge to the opening 35 must be over this edge. Edge 14 therefore forms a weir for the discharg ing water spreading it into a thin sheet entering they opening at right anglesto its Manifestly with my invention applied a Cil much higher Water level may be maintained in the bath tub and this level may be as much higher than the normal overflow level as one desires. p

Many changes and modiications are possible in the structure and in the parts of my invention with the accomplishment of beneicial results, all Within the spirit of my invention and Within the scope of the appended claims as Will be understood by those skilled in the art. lVhile my invention has been particularly described as suited to bath tubs, it will be clear that it is equally suited to other plumbing fixtures and while it has been shown as applied to the overi'ow Waste opening, it will be apparent that it can be equally Well applied to other openings lWith the accomplishment of improved results.

VThat I claim is: Y

l. In a device for adjusting overflow level in a bath tub, a box member covering the bath tub overflow opening and adjustable means for retaining' said member at the desired height respective thereto, said means including suction cups attaching members engaging the interior surface of the tub.

2. In an overiow attachment for bath tubs having waste openings in substantially vertical plane, a box member having an open side and end, adjustable suction means for securing said member over the Waste opening with its open side in registry therewith and with its open end upward.

3. An adjustable overovv attachment for plumbing fixtures comprising a three-sided member having an open end, the edges of said member being provided with llexible means conforming to the interior fixture surface surrounding a Waste opening, the open end of said attachment forming an inner overflow orifice, and suction cups secured to one side of the said attachment being adapted to position the attachment at any desired height.

el. In an 'overflow attachment tor bath tubs a Waste pipe extension comprising a hollow member having an open side and a Waste inlet gasket, means secured to the side edges of said member, suction cups engaging the tub surface, a cross bar connecting said cups and means engaging said member and cross bar to support the aforesaid mein* ber with the Waste inlet uppermost and with its open side against the tub surface over the Waste pipe opening.

5. In a discharge attachmenti'or bath tubs a member of substantially rectangular cross section having a semicircular closed end, a substantially straight open end, three closed sides and an open side, suction means for engaging the tub surfaceJ adjustable means for simultaneously engaging the suction means and one of the closed sides of said member to secure said member over the bath tub discharge opening for the control thereof.

In testimony whereof I have allixed my signature to this specification.

CHARLES HERMANN WAECHTER.
