NOV. 1951 4 s. ISENBERG FAUCET SPRAY ATTACHMENT Filed May 6, 1946 [N VEN TOR.

Patented Nov. 13, 1951 UNITED STATES. PATENT OFFICE FAUCET SPRAY ATTACHMENT Stanley Isenberg, Chicago, Ill- Application May 6, 1946, Serial No. 667,607

This invention relates to faucet attachments, and more particularly to a molded faucet attachment of rubber or the like, which is adapted to provide, selectively, a spray or a full stream of water.

It is one of the objects of the present invention to provide a simple, economical and eiiicient faucet attachment through which water may be selectively discharged in the form of a spray or in the form of a full stream, and which attachment may be turned angularly to [direct the stream or spray in different directions as desired.

It is a further object of the present invention to provide such a faucet attachment which may beeasily molded without requiring the use of a mold which leaves a parting line extending lengthwise of the attachment. This result is accomplished by making the attachment of such a shape that its cross sectional diameter diininishes from a maximum at one end of the attachment to a minimum at the opposite end of the attachment and where none of ,the intermediate portions of the length of the attachment is of a diameter appreciably less than that of both ends of the attachment. By this ar-' rangement it is possible to mold the article and then extract the molded rubber article by pulling the same through the mold. The mold, therefore, does not have to be parted on a line extending lengthwiseof the attachment in order to permit removal of the molded article from the mold.

The present invention contemplates the use of a spray plate having a perforated closure disc overlying .a central opening in the plate, which closure plate is selectively movabletoandfrom a position overlying the central opening in the plate so as to provide, selectively, a spray or a full stream of water. It is one of the objects of the present invention to providesimple stop means for the movable closure which will determine the alternate positions of the closure. The perforated closure is mounted on an arm that is pivoted on the spray plate. In one extreme position the perforated closure engages the side wall of the rubber faucet attachment which acts as a. stop limiting the movement of the spray plate in that direction. The arm which carries said closure has a projection integral therewith which projection also engages the inner wall of the rubber attachment when the closure is in its central or spraying position, thus limiting the movement of the closure.

The attainment of the above and further objects of the present invention will beapparent 1 Claim. (Cl. 299-145) 55 filter screen I2. from the following specification taken in con- 2 junction with the accompanying drawing forming apart thereof.

In the drawing: Figure 1 is a side view of a faucet attachment of the present invention shown as attached to a faucet;

Figure 2 is a longitudinal sectional view through the faucet attachment of the present iii-'- vention;- and Figure 8 is a sectional view taken alongthe line 33 of Figure 2.

Reference may now be had more particular] to the drawing wherein like reference numerals designate like parts throughout. At I is shown the end of a standard domestic type faucet to which the applicant's faucet attachment 2 is'secured. The faucet attachment is made of molded rubber and is quite resilient. It is circular in cross section throughout. It consists of a cylindrical neck 3 having a plurality of inwardly extending annular flanges 4, 5 and 6 for gripping the end of the faucet. Each of theflanges extends downwardly as well as inwardly, the angle of inclination being substantially the same in each case. The top flange 4 is of somewhat greater thickness than are the flanges 5 and 6 and extends inwardly a larger amount, so that the faucet receiving opening formed at the top flange 4 is smaller than the faucet receiving openings in the flanges 5 and 6, whereby the top flange 4 grips the faucet more tightly than do the other flanges. thereby insuring against leakage of water outwardly through the top of the attachment between that flange and the faucet. Thedownward'inclination of the flanges facilitates positioning of the attachment onto the faucet and prevents accidental removal thereof from the faucet.

The lowerend of the cylindrical neck 3 has an integrally formed outwardly flared skirt 8 which has a short inwardly projecting flange Ill, constituting an integral part of the rest of the skirt, for receiving and holding the spray plate in a manner to be more fully set forth as this description proceeds. Also integrally formed with the cylindrical neck 3 and the skirt 8 is an inverted frusto conical portion l I which serves as a funnel to guide the water towards the central opening in the spray plate, as will be more fully set forth as this description proceeds. At the juncture between the top of the frusto conical portion I I and the inner surface of the cylinder 3 there is formed a groove for receiving and holding a metal gauze The inner surface of the cylinder neck has a large number of small inwardly extending circular flanges which extend around the entire inside surface of the neck.

A circular spray plate I1 is positioned within the skirt 8 and rests on the peripheral flange Hi. It is positioned by stretching the rubber of the skirt 8 an amount suilicient to permit the peripheral flange thereof to pass over and around the periphery of the spray plate l1. Pivotally secured to the top sidejof the "spray plate, lkisia fiat sheet'me'tal arm l8 which has at one end thereof a perforated disc [9 and at the other end a short arcuate stop arm 20. The arm I8 is piv oted to the disc H by means of a short-riveti-i;

that passes through the arm [8 and through'a l5 slightly oversized rivet hole in the plate 11, and

which rivet has secured to the lowerendthelffiQf The arm 18 isno'n-roan operating handle 22.

The disclflcanmove. until'it reaches the position indicated in dotted iines in Figure 3, where it is inengagement with the-inner periphery of the skirt 8. Itis thuaapparent that the inner periphery of the skirt. 8 acts: as .a. limiting stop for the movement of the: arm

i8 ineach direction. a

The neck 3 of; thespray attachment is quite. long, being of a length approximately twice itsdiameter. Because. of the length of the neck thespray attachment of the present invention, when it is'attached to a faucet, may be twisted or flexed from the position illustrated-infill linesin'Figure. 1 through a large angle. When this is done the circular flanges on. themterior of the cylindrical neck 3 determine the direction of bending or folding of the, circular neck and assure that the fold shall takeplace between adjacent flanges I5. This increases the. life of the spray attachment. I

It. is to be noted that the perforated disc. [8. has comparatively few holes therein. ,When the disc isin positionoverlying the opening 24 water is guided down. the funnel H where itimpacts- It is also tobe notedagainst. the disc 19. i that the bottom of the funnel portionv H. tel! minates a distance above the perforateddiscfll. Water therefore flows radially outwardly inthe spacebetween thedisc L9 and the..bottom;of

The projecting stop arm 2(1 bears. against the inner periphery of the skirt '8; thus the .funnel- |l,.f1lling the bottom of the. skirt .8

and discharging through. the perforatedlholes, in the, plate I1. When the disc {9 is movedt'o. its opposite extreme position,.as illustrated in dotted lines in. Figure 3, the opening 24' is unco vered. The funnel H directs water towards the center ofthe opening 24 so that all of the water emerges from the funnel as a stream which passes in stream formation through the opening 24.

The rubber spray attachment of the present invention is of a maximum diameter at the lower end thereof; In passing upwardly from the'skirt 8 along theouter surface of the cylindricalneck 3 to the end of the neck there neverdsa suh+ stantial, increase in. diameter.
