BATH OR BASIN WASTE APPARATUS.

SPECIFICATION forming part of Letters Patent No. 765,697, dated July 26, 1904.

Application filed September 23, 1903. Serial No. 174,285. (No model.)

To all whom it may concern.-

Be it lffiown that I, WILLIAM BUNTING, J r., of Brookline, county of Norfolk, State of Massachusetts, have invented an Improvement in Bath or Basin-Waste Apparatus, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

In the waste apparatus of bath-tubs and basins it is particularly desirable that fouling of thepipes may be prevented to as great an extent as possible and that the parts may be readily cleaned when necessary. For this reason it has been found desirable to employ a plug or stopper and an overflow-pipe in lieu of the well-known combined overflowpipe and waste-valve. It is very desirable, however, to provide some convenient mechanical means for lifting the waste-stopper, and various devices of this character have been devised; but many of these devices are too complicated to be practical and are likely to become clogged or to get out of order, so that they fail to operate or operate only with difficulty.

The object of my invention is to provide a simple mechanical means for lifting the wasteplug of a bath or basin which may be easily operated by a hand-lever and which is unlikely to become clogged or to get out of order. I accomplish this object by the means hereinafter described, and disclosed in theaccompanying drawings, in which- Figure 1 is a central vertical section of a bath-tub or basin provided with my plug-op- Fig. 2 is a similar View, on a larger scale, showing a portion thereof. Fig. 3 is a detail plan view of the lifting-tube. Fig. 4 is a cross-section on the line m w of Fig. 2. Fig. 5 is a section on the line y y of Fig. 1, and Fig. 6is a cross-section on the line 2 a of Fig. 2. Fig. 7 is a detail view of a modified form of lifting-tube.

In thedrawings, a indicates a bath-tub, basin, or similar receptacle having a wastepipe 6 leading from thebottom thereof at one end. The pipe I) extends vertically, is provided witha seat 6 at its upper end, and

connected to the coupling 6.

a plug or stopper 0 is adapted to engage said seat and close the passage through said pipe. Said plug is provided with a stem which consists of three radially-arranged vertical wings or guides c, integrally connected at their inner edges, each being provided on their outer edges with a straight portion 0 which engages the inner surface of the waste-pipe and serves to' hold the plug in position at all times. A ring 0 is arranged at the lower ends of said wings c and is cast integral therewith, the outer diameter of said ring being substantially the same as the internal diameter of the waste-pipe Z) and coacting with said wings in guiding. the plug as it is moved vertically. The pipe 5 extends at right angles, so that its bottom is a short distance below the position of ring 0 when the plug is resting on its seat, and a horizontally-extending pipe d is-connected to pipe I) at one end, its opposite end being connected to a three-way coupling 0.

A horizontally-extending overflow-pipef is connected to the side of the receptacle a at one end, its opposite end being connected by an elbow to a vertical pipe f, which is in turn A soil-pipe g is alsoconnected to coupling 6 in line with pipef.

A rod h passes through the rim of the receptacle and is provided with a handle it at its upper end. A tube f extends diametric.

ally through the pipe f and a water-tight connection is provided between the walls of said pipe f and the ends of said tubes, said rod [L passing through said tube, so that the latter serves as a guide for said rod h. The lower end of said rod is provided with a head 2', having acrank-pin c" at its lower end arranged eccentrically of the rod la. vided with a flange 2' which is seated in a boss d, formed on the upper side of the pipe at.

A packing-washer j rests on said flange and is held in place by the ring 70, which is threaded on said boss d. An open-ended liftingtube on is loosely fitted in said horizontal pipe d, the end of said tube adjacent the plug-stem being cut obliquely to provide an obliquelyformed or wedge-shaped portion or projection m, the surface of which extends from Said head is prol the lowest point in the pipe d and beneath ring upwardly from said ring, .as shown in Figs. 1, 2, and 3. A slightly elongated or elliptical aperture m is provided in the upper side of said tube m, and said crank-pin 91' passes through said aperture.

' When the parts are in the full-line position shown in Fig. l, the plug will be seated, closing the waste-opening. If it is desired to lift the plug, the rod h is rotated by its handle, throwing the crank pin 6 forwardly. This causes the liftingtube to be moved forwardly, so that the inclined or obliquely disposed surface of projection m engages the under side of the ring 0 moved forwardly it will act as a wedge or cam and force the ring and plug upwardlyto the position shown in Fig. 2, permitting the water in the receptacle to run down through the pipe]; and tube m into the soil-pipe. As the tube m is forced forwardly it will also be rotated to some extent, the elongated opening m permitting such movement, so that the tube has a direct lifting action on thering during the first quarter-turn, as well as the wedging or cam action above referred to. When the handle is thrown in the opposite direction, the tube will be withdrawn from beneath the ring, permitting the plug to drop to its seat. The parts are so arranged that by the time thering has been moved up opposite the middle of the tube on the plug willhave been lifted the necessary distance and crank-pin 2" will have been moved to its extreme forward position. It will be observed that it is immaterial which way the handle is thrown to lift the plug, and when the plug is lifted to its limit it is immaterial which way the handle is thrown to lower it, so that the operating-rod may be completely rotated in either direction. All liability of the parts being damaged by improper manipulation is thus avoided. If necessary, the tube m may be removed through the clean-out opening 6 in (this coupling 6 after firstdisconnecting the r0 If it is desired that the plug be lifted directly bythe lifting-tube and not partly or' wholly by the wedging action thereof, I may provide the front end of the tube with a straight finger or projection a, (see Fig. 7,) which extends beneath the ring 0 in all positions of the crank-pin c" and tubes. By this means the plug may be lifted to an extent approximately equal the diameter of the tube, and for some reasons 1 consider this construction preferable to the one before described.

The particular means for operating the lifting-tube described is not wholly essential, al-

though it is much preferable, and other means may be provided which are within the spirit and scope of my invention.

Having thus described my invention, .what
