DETACHABLE `SINK STRAINER Filed March 10, 1932 'their' wwwa/13 Patented Apr. 4, 1933 rUNITED STATES PATENT ,on-1c .CLIFFORD MERCIER AND FREI) DIETRICH, F LOWELL, MASSACHUSETTS DETACHABLE SINK STRAINER Application led March 10, 1932. Serial No. 598,064.
The present invention relates to a detach able sink strainer.
The principal object of this mventlon 1s the provision of a detachable sink strainer,
which is so formed `that whenattached to the usual, perforated sink strainer it will effectively excludey sediment and Aprevent clogging of the sink.
, Another object of the invention is theprovision of effective yet simple, cheap and novel meansffor readily and detachably securing the strainer to aV sink, basin, bathtub, or the like.
Other objects of the invention will becomei shown in Figures l and 2 of the drawing,
the numeral 1 denotes a sink having the customary drain opening 2 into which is "fitted the usual perorated sink strainer 3. To prevent sediment and kitchen refuse from clogginglthe sink, the strainer 8 is appliedV to the sink by means of the pin 4, which has the hooked end 5 so shaped and formed as to be readily insertable through any one of Athe perforations 6 in the sink strainer 3. To
l prevent the hook shaped securing pin Afrom dropping into the drain pipe, a cross pin `7 is mounted through a horizontal opening in the pin 4 and spaced a suitable distance from the hooked end of the p-in so as to permit the hooked end to be readily` inserted ina perforation 6 of thesink strainer and retain it therein. -K
The detachable strainer, shown in Figures 1 and 2, comprises a substantially conical or Ytruste-conical portion 8, having a at rim 9 of relatively great area adapted to cooperate with and be pressed against the surface of the sink strainer V3 by a compression spring l0 interposed between the top ofthe strainer and a stop disposed at the upper end ofthe strainer attaching pin l4. The conical portion of the strainer and the iianged portion are provided with relatively small perforations y11, which are smaller ythan the perforations 6 in the sink strainerV 3. These relatively small perforations prevent the accumulation ofscum and sediment upon the sink strainer to a marked :degree and ei'ectively prevent the clogging of thedrain.
The upper end or apex portion of theconi- 'cal strainer is provided with, a cylindrical open extension 12, forming, a shoulder-13 where it meets the conical portion 8 ofthe strainer and to which the compressionspring 10 is suitably secured, as by soldering, 'brazf ing, or welding as indicated at 13. The spring atits upper-end has soldered thereto, Y at 17, a sheet metal member 14 provided with an elliptical slot 15 and laterally extending] enlarged portions 16, the latter being adapted A to be engaged by the fingers ofthe'u'ser to push against and depress the said member in order to compress jthecoil spring 10, when attaching the strainer to the sink. The coil r spring is retained in compression bythe cross pin 18 on the mam pm 4, which serves as an 'abutment or stop for the member 14. I
To attach the strainer, .the p in'4 isfinserted Vwith the hooked end within a perforation 6.v
in the sink strainer 3, as shown in'Figure 1.
l After'the pin has been inserted and arranged vertically, the conical strainer isinserted over the pin; the finger piece or member 14 is ai'- ranged withthe elliptical opening 15 in alinement with theabutment or stoppin 14;"the 'member 14 is then depressed below the' stop pin 18 and given a quarter turnso that the elliptical opening 15 is out of registration with the stop pin, `asfshown in Figure 2.
When thus mounted, it is evident that the structure describedbecomes a rigid whole for the reasonthat the spring 10 forces the pin 4 upwardly and maintains the hooked end*5 securely against the under face of ,thesink strainer 3.
When the (conical strainer has become clogged and it is desired to permit the outflow of the liquid contents Vof' the sink, the
strainer is raised slightly from its seat by. lifting it, against the spring 10, which will permit the contents to drain out between the strainer flange or rim 9 and the perforated sink strainer 3. v
Figure 3 shows a modification of the invention which is provided with a different means for securing the strainer in a sink. In this Ymodification, the perforated conical strainer 18 iS PIOVCled With a relatively wide rimmed perforated flat flange 19, the size of the perforations 2O in the conical and rim portions of the strainer being considerablysmaller than the perforations 21 in thesink strainer 30. As in the form of the inventionY shown in Figure l, the strainer is secured in place by means of a hook shaped attaching pin having the hooked end? O- inserted through a perforation inthe sink strainer and provided with the stop pin to prevent the hooked attaching pin from dropping into the drain pipe.y The upper end of the attaching pin extends slidably through a collar 22 secured withintheapex opening 23 of the conical strainer. The collar is preferably formed with: a bell mouth or flared opening 24 to facilitate the insertion of the attaching pin within the collar, anda threaded'opening 25 is formed in the side of the collar for the receptionof a winged set screw 26 for securely retaining thestrainer seated in the sink.
To drain the sink when the` conical strainer has become clogged,Y the` set screw 26-is loos'- Y cned-and the -strainer raised a sufficient height ,4o v l Vmaybe fabricatedout off several distinct portogpermitl the liquid contents ofthe sink tol drain out between the flanged portion (19 and `itsseat on the sink strainer.
While the strainer shown andr'described (herein may be made of any-suitable metal,
such as, copper, aluminum, or the like, we preferably use dipped tin.
It will also be understood-that our strainer y tions, which are later assembled, as by soldering, brazing, or welding, and that it may also be made Yby stamping out of-4 unitary sheetmetal blanks.`
v Itis clear, therefore, that the above described.k forms ofthe invention are intended to be merely illustrative ofthe objects of the invention, and it will be understood that a .variety of: different modifications are intended to come within the terms. of the following l. Xn-auxiliary strainer for kitchen sinks,
'comprisinga rigidrpin adapted to belmounted .onV aj sink strainer, said pin having a smooth shank, ank auxiliary strainer element slidable along; said,r pin, and` cooperating Vmeans Ybe- -tween said auxiliary .strainer and.` smooth shank for mounting said auxiliary strainer element on said pin and dismounting it therefrom while the pin remains in place onk the sink strainer.k Y
Y v2,1111 combination with a perforatedsink strainer, a pin having a smooth shank, means for securing said pin on said strainer and substantially preventing movement thereof along two opposite vertical directions, a second strainer slidable along said pin and normally adapted to overlie said sink strainer, and cooperating means between said auxiliary strainer and smooth shank for mounting said second strainer on said pin and disniounting it therefrom.
3. In combination with a sink strainer, a perforatedcentrally bulged strainer having a relatively wide flat rim adapted to rest against said sink strainer, a hook shaped attaching pin havingy the hooked end thereof engageable with the sink strainer, and having the other end of said pin extendingthrough the apex of the bulged portion of the strainer, abutment means, a spring confined between said abutment means and the apex portion of the bulged strainer, and quickY detachable means between said abutment and said pin, whereby the strainer may be slipped over the last mentioned end of the pin while the pin remains engaged with the sink strainer.

5. In combination with a sink strainer, a substantially conical shaped perforated l strainer having a perforated relatively wide flaty rim adapted to rest against said sink strainer, a smooth hook shaped attaching pin having the hookedend thereof detachably engageablewith the sink strainer, and having the other end thereof extending slidablyV Y forated strainer having a perforated relativelyv wide fiat rim'adapted torest against said ksink strainer, a'hook shapedl attaching pin havingthe hooked end thereof engageable with the sink strainer through a perforation thereof, and having the other end of said pin v' extending through the apexofthe conical strainera spring abutting at one end the 125 apex portionsof the conical strainer,jand 'a stop member removably secured'to the' pin,
whereby-the conical strainer may be removed Y Y from said lpin whileY the latter is in operable engagement with the sink strainer.
