{Specification of Lettersiatent. Patented Oct, 12, 1909.

f Application filed July; 25, 19.0.8. Serial No; 445,390.

To all whom it-may concernf Be it known that I, HARRY S. Mnonoon, a citizen of-the tUnitedStat'es, residing at Trenton, county .of Mercer, State of New Jersey, have invented certain new and useful Improvements in ater-Closet Coupe lingsyand I do herebydeclarethe followingito be afull, clear, and exact description of the invention, suchaslwillienable others skilled inthe art'to which it appertains to make anduse'the same.

This invention relates. 1 to couplings .:for the flush I pipes of water closets I and has for its object to provide a simple, cheap ,and efficientcoupling. between the-closet bowl and the water supply pipe, that will permit thev bowlto be accurately connected -.withsaid pipe without bending; or deforming :the' latter, and tothis en'dsaid coupling comprises an elongated water inleto ening 1n the bowl, a nipple adjustable longitudinally :of isaid opening and meansfforrlocking said nipple to the bowl in adjusted .relation in said opening, and preferably there is provided a packing gasket, of rubber or the like, surroundingthe nipple and covering the portions-o'f the. opening in the bowl not occupied by the nipple.

A convenient and approved form of the invention is illustrated in the accompanying drawings, in which: V

Figure 1 is a vertical longitudinal section of a siphon jet closet having the improved coupling applied thereto. Fig. 2 is a horizontal section on line 22 of Fig. 1 looking in the direction of the arrow. Fig. 3 is an enlargeddetail of the coupling nipple in side elevation. Fig. at is a bottom plan view Referring to; thedrawings, a indicates the bowlof a water closet of the siphon jet type which is provided'atthe rear of its upper face with awater inlet opening Z) having a diameter longitudinally of the bowl considerably greater than the diameter trans- I versely of saidbowl so that said opening is of. generally elliptical form, viz: elon- :gated ina direction toward the rear. of the bowl. The loweredgeofthe rim of said opening is preferably provided with diametrically opposite recesses 11, the purpose ofwhich will be explained later.

Occupying thelopening b is a short pipe section ornipple Z of ag'diameter somewhat less than the shorter or/transverse diameter of said opening. .Oppositely disposed on thelower.endofsaid nipple are two lateral lugsave, .Wl11Cl1;LI'6 adapted to engage the recesses 0, 0, and-assist in looking the nipple tolthe-bowl. Saidrecesses c, 0 areconsiderably .longerthan the lugs e, c are wide, to permit the ,latter to: engage the said recess in-all adjusted positions of the nipple. The upper end .of the nipple is. externally screwlillI-QZLClGClitO .receivea clamping-nut g which is provided with a basal flange of-sulticient diameter to cover the-opening b when said nutais set down on the top of the bowl to secure the nipple in place.

1 In. OIdQl'ftOll'lfi kB an absolutely tight joint between the :nut. and the bowl .and to seal 'the-portionsiof the opening b gsurrounding the nipple, cl a packing ringorwvasher 7:. of rubber, orQther-suitable material, is applied about )said nipple below said nut and. is

clamped firmly against the bowl and over the opening .6 when the ,nut lg is screwed down on .nipplelcl.

In the forms of closets heretofore employed, to connect the flush pipe to the bowl, the latter is fixed in the position on the floor determined by the setting of the soil pipe. The vertical position of the flush pipe however fixed by the location of the flush tank and the lower end of the flush pipe seldom registers accurately with the inlet opening or coupling nipple in the bowl. Therefore it has been necessary generally to bend the inlet pipe to bring its lower end in exactvertical registry with the inlet to the bowl, or to provide a double elbow between the supply pipe and the bowl, both of which expedients are obviously objectionable. By means of the present invention no distortion of the inlet pipe is required, nor are extra bends or elbows required to make the coupling between the flush pipe and the bowl, and moreover a careful adjustment of the relative positions of the soil pipe and the flush tank is no longer necessary.

It will be noted that when the closet is set in the position determined by the location of the soil pipe, and the flush tank is secured to the wall or other support back of the bowl, the flush pipe is then dropped vertically from the tank, and nipple d, is adjusted longitudinally in the opening 5 until it lies directly below the end of the flush. pipe which may then be accurately connected to said nipple by any of the customary forms of joints or pipe couplings, after which the nut g is set down on the threads of said nipple (Z until said nipple is securely locked to the bowl and washer h is clamped over the opening b. It will be noted that the nipple 61 moves freely in the opening 1) until the nut g is tightened, but when this is done the lugs e, e bind against the recessed shoulders of the rim around the opening, and lock the nipple rigidly in position. The nipple (Z may be readily removed from or applied to the bowl by turning said nipple until the lugs e, a lie in the longer diameter of the opening I), as will be apparent from an inspection of Fig. 2. To permit said nipple to be turned in the opening Z) without applying a wrench to the threaded end of said nipple the interior of the latter may be conveniently provided with two or more lugs i, i to be engaged by a spanner or other special tool.

What I claim is 1. A water closet bowl having an elongated water inlet opening, in combination with a coupling nipple adjustable longitudinally of said opening, and means for locking said nip-ple to the bowl in adjusted relation in said opening.

2. A water closet bowl having an elongated water inlet opening, in combination with a coupling nipple adjustable longitudinally of said opening, a packing gasket surrounding the nipple and covering the .portion of the inlet opening not occupied b said 111 ale and means for lockin said nipple to the bowl in adjusted relation in said opening.

3. A water closet bowl having an elongated water inlet opening, in combination with a coupling nipple adjustable longitudinally of said opening, said nipple having lateral lugs to engage the lower riin at the sides of said opening and having exterior screw threads on its outer end, a nut eugaging the threaded end of said nipple,

and a packing gasket surrounding said nipple and adapted to be clamped between said nut and the bowl to cover said opening.

4. A water closet bowl having an elongated water inlet opening, in combination with a coupling nipple having lateral lugs on its lower end to engage the under sides of the rim surrounding said opening, a nut on said nipple to clamp the same in the desired position longitudinally of the opening and a packing gasket surrounding said nipple and adapted to be clamped over said opening in the several adjusted positions of said nipple.

In testimony whereof I afiix my signature, in presence of two witnesses.
