WASTE AND OVERFLOW FIXTURE FOR BATHTUBS.

Application lcd July 11,

My invention relates to interconnected Waste and overflow fixtures which are concealed behind the wall of a bath tub; in some instances being located within the wall of the room in which the tub is located.

IThe main object of my invention is to pro- Vide for the withdrawal and insertion of the waste valve and its operating'member through the waste opening and the overflow opening of the fixture, respectively, without the necessity of opening the wall or of dismembering the fixture in any way, except for the removal of the escutclieon or shield covering the overflow opening, for such withdrawal or insertion.

A further obj ect of my invention is to provide a waste valve operating member of a pliant and/or flexible type, which member is normally disposed within the overflow pipe and may be withdrawn and inserted through the overow opening for the purpose of' adjusting or replacement without breaking the joint between said overflow pipe and the tub.

And a still further object of my invention is to provide a pliant rod or stem for operating the waste valve to open position in the form of a closely `coiled member of spring wire, having a weighted end to engage one end of a lever carrying the waste valve and carrying guiding means permanently positioned at suitable points; such pliant weighted member being free to rise and fall within the overflow pipe under the influence of an operating handle disposed within the tub and which may be centrally located with respect to the overflow opening. The overflow opening is normally closed by a shield or escutcheon having suitable ports inthe lower part thereof for the passage of overflow from the tub.

These and other features of my invention are more fully described hereinafter; reference being had to the accompanying drawings, in which:

Figure 1, is a sectional elevation of one end of a bath tub showing the waste outlet and the overflow pipe and the improvements forming the subject of my invention connested therewith.

Fig. 2, is an enlarged sectional elevation, partly broken away, taken on the line II-II, Fig. l, and looking in the direction of the arrow m, and Y Fig. 3, is a sectional plan view taken on the line III-III, Fig. 2.

bined stem and lever consisting of a series of links, 6a, 6b, 6, 6d, and 6", pivotally connected together for movement in one direction, but normally forming a relatively sti arm for a purpose to be described.y The link ais in threaded engagement with the pop-'up valve 6,- and a nut 7 may be employed to hold the same securely thereto. kThe links 61260, 6d and 6e form a lever for the pop-up valve; the fulcrum of which consists of' a pin 8, which may be suitably connected, as by riveting, to the link 6d. The link 6*l has a threaded portion Gfupon which is adjustably mounted a panor platform 9, for a purpose to be described; such pan being held in itsadju'sted position by means of a. set screw 9a. j

The overow pipe, indicated 10, is connected at its lower end to the T fitting 5 in the usual manner, and at the upper end to an elbow 11, which in turn is connected to the tub by a sleeve 12, forming the overflow outlet and fitting within an opening 12av in the wall of the tub. These parts are in perma nent engagement with the tub. The pan 9l at theend of the link lever carrying the popup valve 6 is in. axial alignment with respectv to the overflow pipe and the operating means for this valve, which engage said pan 9, are

disposed within said overflow pipe 10.

A particular featureof my invention comprises the means for operating the pop-up valve by engagementwith the flexible lever thereof. Located within the overiow pipe 10. is an operating member for the pop-up valve, consisting of a pliant and/or flexible rod or stem of coiled-spring wire indicated at 15, carrying a series of guiding collars 16, which may be brazed or otherwise secured thereto; each of said guiding collars having a plurality of arms 16a, loosely fitting within the overflow pipe so as to guide the operating member during its vertical movements but without aecting the freerisingand falling tively tosaid flexible stem so as to provide for the proper movementJ of the latter to operate lthe pop-up valve. The weight may be locked to the stem`17 by a nut 18a.

The upper end of the pliant operating member 15 has fitted thereto a tubular member 19, having an apertured projection 19a for pivotal engagement with Van arm 20, of a crankv21, secured to the end of a stem 22, journaled in a support 23, within the overflow opening, and having an operating handle 24, disposed within the tub. The overflow opening of the tub is provided by the sleeve 12, in threaded engagement with an elbow 11, at the upper end ofthe overflow pipe 10. A cross-'bar 25, secured to `the `flange 12b of said sleeve carries the support 23 in which the stem 22 is j ourn'aled; said support being also provided with a threaded socket 23, receiving a iianged collar 26 bored centrally for the :reception of an enlarged portion of the stem 22. These parts will be enclosed by a shield or escutcheon 27, having openings 27a in vthe lower part of its flange for the escape of overflow, and being retained in place by the flanged collar'26.

The crank member 21 at the end of the stem 22 is provided Vwith an arm 31, for engagement withy stop projections 32 and 32a, which may be integral with the wall of the elbow 11. Then in theraised positiom'as illustrated in the drawings, the operating handle 24 disposed within the tub will. lie in a substantially horizontal position toward the right, looking-in the direction of the arrow a', Fig. 1, (toward the left as indicated by dotted lines, Fig. 2), and tlie'a'rm 31 is in engagement with the stop projection 32; In

such position the pliant operating member 15 is in the raised position, and the pop-up y valve is seated; Lclosing the waste outlet.

1 Then it is desired to open 'the waste outlet,

the handle is thrown over 180o, until it occupies a substantially horizontal position,

but directly opposite the position it occupied with the pliant member 15 in the raised position," and in such changed position the arm 31 will engage the opposite projection 32a. Such actionpushesdown the pliant member;

fthe weighted end engages the pan-9 at the end ofthe jointed lever for the pop-up valve, and the latter is moved on its fulcrum to elevate ythe waste valve from its seat.

.The pop=up valve with the links'xb, e seq., is pofisiiicient Iweight to .remainA in the closed position, when the pliant opera-ting rod 15 is in the elevated position, as indicated in Fig. 1 of the drawings. It will be under stood, however,ithat when the pan 9 is engaged by the operating means located within the overflow pipe, the link lever will be moved and the pop-up valve will be raised from its seat in a vertical direction; such valve being provided with fins or guides 6g, which insure such operation. Pop-up valves of this type, operating in a substantially similar manner are more or less well knownand, except for certain details, this pop-up valve and its link lever forms no part of my invention.

The pliant and/o1' flexible operating member is removable through the overflow open ing formed bythe sleeve 12, as indicated in dotted lin-es; such opening being accessible by removing the operating handle 24, collar 26, shield 27, and the cross-bar 25 which provides the journal bearing support for the stein 22 of the operating handle. The popup valve may be readily removed from the waste outlet, after it has been elevated; the several links which make up the stem and lever of the same flexing on their `pivotal connections to permit such action.

An important feature of my inventionl resides in the fact that :due to the plianey and/or iiexibilityof the operating member disposed in the overflow pipe, no damage can be occasioned the valve 6 closing the `waste outlet, or the flexibleV lever connected to the same, should a user of the tub happen to stand upon said valve when in the raised and open position. By having the pan 9 adjustable'with respect to the flexible lever carrying the valve 6, it is possible to maintain said pan in central position with respect to the overflow pipe should variations exist between the centre of the waste opening and the centre of said overflow pipe. i
