' REMOVABLE STOPPER AND STFWNER.

A plication filed October 9,1905. SerialNo. 281,996.

Specification 'of Letters Patent.

Patented. Sept. 2'5, 1906.

To all whom it may concern:

Be it known that I, EDMUND P. BODEN, a citizen of the United States, residing at Santa Olara, in the county of Santa Clara and State of California, have invented certain new and useful Improvements in Removable Stoppersand Strainers, of which the following is a s ecification.

his invention relates to a removable strainer and stopper useful for kitchen and other. sinks or for any such apparatus in which it is desirable sometimes to strain the passing liquid and sometimes to entirely stop the passage thereof. I

The object of the present invention is to provide a device of this character WhiOh'Will be cheap to manufacture and si'mlp'le'and effective in operation and which wi facilitate the flushing or opening of the pipe into whichthe liquid passes from the strainer in case of its being stopped up. i

In the accompanyingdraw-ings, Figure 1 is a plan view of the device, showing the drain holes closed. Fig. 2 is a sectional view of the.

same in the same position. Fig.3 is a similar view in the open position. Fig. 4 is a perspective view of 'the up er side of the cup. ig. 5 is a similar view 01? the upper side of the shutter. Fig. 6 is an enlarged horizontal section through the stopper and socket.

Referring to the drawings, "1 represents an annular plate adapted tobe secured. by screws to the sink or other part which it is desired to drain. The central hole of this plate is formed with a depending flange 2, the inner surface of'which tapers or converges inwardly downward to form a tapering seat for a cup 3, the wall of which correspondingly tapers downward. The-bottom of the cup is formed with a Series of holes 5, arranged radially in pairs. Said cup is also formed with cal or elongated form, preferably formed by stamping upward the metal of the cup into the desired shape. Through'the center of this stop is.a hole 7 for the passage of a bolt 8.

' Upon said on rests a shutter 9, which is also the metal of the shutter. This socket 1O lies formed, li e manner as the cup,fwith an approximately elliptical or elongated socket 10, formed, preferably, by stamping upward overthe elongated stop 6, but covers the same loosely, so as to allow of a limited angular motion in either. direction of the shutter relatively to the cup. The shutter is also formed with a circular series of holes 11, ar-

- ranged-radially in pairs andcorresponding wi'ththe holes 5, and at one end of the angular movement of the shutter each pair of holes therein registers with a pair of holes in,

the cup'; but when moved in the other direc tion the holes fail to register and lie, respectively,, against closed portions of the cup. and shutter thus entirely stoppingthe passage of liquid through said holes. Through the cone ter of the socketed portion of the plate is formeda square hole 12, intowhichfits the squared upper portion of the bolt 8 ,the head 14 of said bolt resting upon said socket. The body of the bolt is passedthrough theround hole 7 in the stop on the cup and has a close fit therethrough, but is spaced from the side of the stop on theunder portion thereof, andin said space a coiled spring 15 ispassed around said bolt. It will of course be understood that in place of a coiled spring a flat platespring could be used. of the bolt is screwed the nut 16.

The operation of the device is therefore as follows:- When it desired to use it as a strainer, the shutter is turned so as to bring. the holes in the shutter and cup into register with eachother, the body of the socket'serving as a convenient holding means forso turning it. To-close the device, the shutter is turned so that the holes no longerregister Upon the lower end with each other, and then, on account of the pressure ofthe shutter against the cup produced by the spring 15, a water-tight joint is,

effected between said shutter and cup, and

' the passage for the water is entirely closed.

This provides a convenient arrangement where it is'deslred to use, for instance, a smk' as a receptacle to hold a largebody of water. It .is also convenient in sinks for collecting the small particles of crumbs and other mat-. ter, asthe holes may be stopped, and then suchparticles may be brushed into the cup, which may be then lifted and dumped mto any desired receptacle, and the cup can then easily be cleaned by holding it under a faucet.

This, device also provides areadymeansfor flushing the drain-pipe in case it becomes stopped up. For this purpose thecu would be removed, and in place thereof W011 dbe inserted a tightly-fitting cup. provided at the center with a threaded flange, upon which a hose could be screwed. Then by attaching the hose to a faucet. and holding down the cup water can be forced into the pipe under great pressure, thus forcing the water through the trap inthe pipe.

While I have herein for convenience referred to the invention as in use with a kitchen-sink,- it is to be borne in mind that the combined strainer and stopperhas many other uses, all of which I do not think .it necessary herein to enurnerate; but I may instance that instead t being used as a stopper for hqulds 1t may lIl certain cases beadvantag eously used as a stopper forgas."v

I claim-' 1. In acombined strainer and stoplper, a main plate having a depending inwar -taperingannular flange, and a cupentirely separable from the plate and having a downwardly-tapering wall fitting snugly Within said flange, the bottom of the cup below said wall being provided with means for permit-v ting or preventing at will the passage of liquid, substantially as described.

2. a combined strainer and stop er, a main platehaving a depending inwar l -ta- 'pering annular flange, and a cup entirely separable from the plate and having a downwardly-tapering wall fitting snugly within said fiange, the bottom of the cup below said wall being provided with means for permitbelow said plate to form a receptacle for debris, substantially as described.

4.. In combination, a plate having a circular. seat, a circular device removably secured in said seat and having a series of holes, a shutter-movable over said device and having a corresponding series ofholes adapted to register in one position with the holes in the device, the device and shutter havin the one an elongated stop and theother an e on ated socket receiving said stop, said socket: eing larger than the said stop to permit of limited movementgof the one-within theother, and

get-her, substantially as described,-

5. In combination, a plate having a circu means for holding said shutter and device tolar'seat, a circular device removably secured in said seat and having a series of holes, a-

sliutter movable over said device and having a corresponding series of holes adapted to regist'er'in one positibn with the-holes in the device, the device and shutter having the one an elongated stopand the other an elonated socket receiving said stop, said-socket ein larger 'than'said'stop to permit of-ili mite movement .of the one within theother, and means for holdingsaid shutter and device together, said means comprising a bolt and a spring aroundsaid bolt, the stop being hollowed out on its under side'to receive said sprin substantially as described.

In combination, a plate having a circu-. lar tapering seat, a cup having a series of holes, and a' tapering wall fitting within said seat, and a shutter indvableover said cup and having a corresponding series of holes 7 adapted to register in one position with the '-,holes in the cup, said'cup and'shutter being.

provided with means for limiting the movement of the shutter relatively to the cup, said means consisting of an elongated sto in one element and an elongated socket in t e other element receiving said stop and bein larger 1 than the same, and with means for olding said cup and shutter together, substantially as described.
