ATTORNEY UNITED STATES PATENT OFFICE FAUCET ATTACHMENT James C. Thomas, III, El Segundo, Calif.

Application March 14, 1945, Serial No. 582,673

Claims. 1

The invention relates to improvements in a faucet attachment with the provision of means for securing the attachment to faucets of different sizes.

An object of the invention is to provide a faucet attachment integral with' and forming the neck of the top of a container, to support the container from the faucet.

Another object is to provide the container top with a compressible neck adapted to be clamped on the faucet spout.

Another objectl of the invention is to provide the container neck with a sleeve washer to prevent leakage through the neck and to prevent the washer from working loose or blowing out under fluid pressure when th'e faucet attachment is in use.

Another object of the invention is to restrain expansion of an auxiliary sleeve washer or reducer for a smaller size of faucet, by a cover for the container neck.

For further details of the invention, reference may be made to the drawing, wherein:

Figure 1 is a vertical sectional view through a mixing device provided with the faucet attachment of this invention.

Fig. 2 is a vertical sectional view on line 2-2 of Fig. l, looking in the direction of the arrows.

Fig. 3 is an enlarged view in side elevation; and',

Fig. 4 is a plan view of a toggle for one form of compressing device or lclamping band for the I faucet attachment of Fig. l.

Fig. 5 is a vertical sectional view with parts broken away of the faucet attachment of Fig. 1, with attachments to accommodate a smaller faucet.

Fig. 6 is a vertical sectional view with parts broken away of a modified form of faucet attachment.

Fig. 7 is a sectional view on line 1-1 of Fig. 6.

Referring in detail to the drawing, the mixing device I is disclosed and claimed in my copending application, Serial No. 582,672 led March 14, 1945, for Mixing chamber, and generally comprises a container 2 having a cap or closure 3 removably held in position by lugs 4 and 5 on the side walls of the closure 3, and companion recesses 6 and 'I on the container 2. All of the parts illustrated except the spring 8 for relief valve 9 and the clamping band I0, are cast of moldable material such as plastic, and the side walls of the container 2 are flexible enough to permit compressing them together so as to release or engage the lugs and recesses 4 to 'I so that the cap 3 may be removed from or mounted on the container 2.

Mounted in the cap 3 is a transverse conduit II, one end I2 of which serves as a relief outlet having a relief valve 9 held closed to its seat I3 by spring 8 when the mixed fluid outlet I4 is open or unrestricted. Depending from the transverse conduit II is a suction tube I5 having a check valve I6 which opens t0 suction and closes when there is pressure in the suction tube I5. The upper end of suction tube I5 has an outlet I1 which is in the conduit I I, facing the outlet I4.

Between the suction tube I5 and the relief outlet I2 there arises from conduit Il a sleeve I8 having internal screw threads I9 which engage the external threads 20 on a hollow thimble 2| which serves as an inlet. The cap 3 has integral therewith a neck 22 having a plurality of longitudinal slots 23, here shown as four in number, whereby the neck 22 is flexible or compressible. Inside of the neck 22 and over the slots 23 lits a rubber sleeve washer 24 having at its inner end an inwardly projecting flange 25 which rests and nts on a flange 2B at the inner end of the neck 22. Both the flanges 25 and 25 have central apertures indicated at 21 through which the thimble 2I projects. To prevent leakage between the flanges 25 and 26 and to hold the sleeve washer 24 in position and prevent it from blowing out, the ilanges 25 and 26 are clamped together between the flange 28 on the thimble 2| and the upper end 29 of the socket I8. The body of sleeve 24 prevents leakage through slots 23.

The sleeve 24 receives the faucet and the compressible neck 22 and sleeve 24 are clamped around the faucet spout to support the mixing device I on the faucet spout. One form oi clamp on the neck 22 is indicated in Figs. 1 to 4 as comprising a band 30 of wire having its ends connected to a toggle clamp 3| having a handle 32 which can be moved up or down to clamp or unclamp the band 30.

The cap 3 is provided with a shoulder 34 on which ts the lower edge of an auxiliary cap 35 having a central aperture 36 through which the faucet spout passes. In the modiilcation shown in Fig. 5, when using a faucet spout too small to fit in the sleeve 24 in Fig. 1, use may be made of an auxiliary sleeve 31 which ilts in sleeve 24, the cap 35 being provided with a removable insert ring 38, of plastic, having an internal diameter to fit gi'id restrain expansion of the outside of the sleeve In the modification shown in Figs. 6 and 7. instead of using the clamping band 30 to compress the flexible and compressi-ble neck 22, use may be made of a cam lug such as indicated at 39 on the upper end of each of the four neck portions like 45; that is, the neck has four flexible portions such as 45, as there are four longitudinal slots such as 40 which divide the neck into four pieces like 45. Four companion cam lugs like 4I are arranged around the inside of the top of the cap 42. The cap 42 rests on a shoulder 43 of the cap 44. By rotating cap 42 in one direction or the other, the four neck pieces such as 45 can be bent in to compress the same and the sleeve 46 to clamp the faucet spout, or to release it.

It will be apparent that various modifications may be made in the invention without departing from the spirit of the following claims.

I claim:

1. A faucet attachment comprising a compressible c ollar having an outer open end to receive the faucet spout, said collar having an inner end having an inwardly projecting flange having a central aperture, a resilient Washer having a sleeve portion fitting in said clTar'and having a flange portion fitting on said collar flange, said Washer flange having a central aperture, a hollow thimble extending through said aperture and having exterior screw threads, said thim-ble having a flange overlying said washer flange at one the other side of said collar flange, and means for compressing said flexible collar and washer sleeve portion.

2. A faucet attachment comprising a collar of flexible plastic material having spaced longitudinal slots extending through one end of the collar, said collar having an integral inturned flange at the other end thereof, a washer having a sleeve portion fitting in said collar over said slots, said washer having a flange fitting on said collar flange, said flanges having aligned central apertures, means having a uid passage therethrough extending through said apertures for clamping said ilanges together and means for compressing said collar and washer sleeve.

3. A faucet attachment according to claim 2' wherein said compressing means comprises a band having a toggletherein.

4. A faucet attachment according to claim 2,

wherein said compressing means comprisecam lugs on the outside of said collar, and a cap tin ver said collar, said cap having a central faucet receiving aperture and having companion internal cam lugs.
