MIXER DEVICE Filed Aug. 29, 1956 ATTORNEY MHXER DEVICE lloseph Akselrad, Douglaston, and Salvatore Spiezio, Brooklyn, NX.

Application August 29, 1956, Serial No. 606,840

l Claim. (Cl. 239-408) The present invention relates to a mixer deviceand particularly relates to a mixer device which may also serve as an aerator and which will permit the mixing of water with various types of liquid or other fluids.

It is among the objectives of the present invention to provide a simple, inexpensive attachment which may be readily applied to faucets or other liquid outlets and which may be used by the housewife to regulate mixtures of water and detergent or water and other materials to give different detergent mixtures and which will also readily enable supply of clear aerated water with a minimum of manipulations and without instruction or skill on the part of the housewife.

Another object is to provide an attachment to give proportional mixing of liquid and water and particularly liquidV detergents and water which may be readily used at any angle or position and which will have wide range so as to give either clear aerated water or a light detergent mixture for washing glasses, a medium detergent mixture for washing dishes and strong detergent mixtures for washing pots and pans.

A further object is to provide a broadly useful mixture device adapted to be attached to a wide variety of faucets or liquid outlets which may be employed for mixing a wide variety of materials with water such as liquid fertilizers, liquid detergents, liquid surface-active materials for industrial, commercial, or household use, and which will give assurance of correct proportionment of the various liquids to be mixed without difficult manipulation or special adjustments.

Still further objects and advantages will appear in the more detailed description set forth below, it being understood, however, that this more detailed description is given by way of illustration and explanation only and not by way of limitation, since various changes therein may be made by those skilled in the art without departing from the scope-and spirit of the present invention.

ln accomplishing the above objects it has been found most satisfactory in accordance with one embodiment of the present invention to provide an attachment which will enable itself to be readily mounted upon a faucet or other water or liquid outlet. This attachment will haveV an outlet screen and an intermediate restricted passageway havingv an enlarged outlet iiow passage before the screen which may be variably blocked by adjustable plugs.

The passageway between the inlet and the screen and before the plug is desirably provided with an inlet connection which may consist of a plastic flexible tube from a liquid container, bottle or reservoir receiving the liquid mixture which is to be incorporated with the water to form the predetermined proportioned detergent, fertilizer or other liquid mixture.

,arrangement showing '2,919,073 Fatented Dec. 29, 1959 This intermediate passageway is provided with a readily manipulated hand cutoff valve so that the mixing device may be caused to supply aerated water without admxture of other fluid.

TheA most unusual feature, however, of the present invention resides in the provision of the adjustable insert or plug usually positioned in a cylindrical recess or chamber with the plug having a polygonal cross-section so that various peripheral passageways are formed depending upon whether said cross-section is triangular, square, pentagonal, hexagonal or octagonal.

Moreover, an unusual feature of the present invention resides in the fact that this plug or insert may bel adjusted closer or farther away from the restricted passageway with the result that the proportionment control is readily adjusted.

This adjustment may be achieved by various means of changing the position of the plug or insert but one satisfactory method of accomplishing this is by beveling or obliqueing one side or end of the plug or insert which will permit the position of the plug or insert to be changed by moving in a follower member or screw which will cam the plug inwardly or permit it to move outwardly under the force of a spring.

With the foregoing and other objects in View, the invention consists of the novel construction, combination and arrangement of parts as hereinafter more specicallydescribed, and illustrated in the accompanying drawings, wherein is shown an embodiment of the invention, but it is to be understood that changes,variations and modifications can be resorted to which fall within the scope of the claim hereunto appended.

In the drawings wherein like reference characters denote corresponding parts throughout the several views:

Figure l is a transverse sectional view of a form of mixing device according to the present invention showing the mixing device with a conduit leading to a container for liquid detergent or other liquidv to be mixed and having an adjustable hexagonal plug in position to vary the proportionrnent;

Fig. 2 is a fragmentary transverse sectional view taken upon the line 2 2 or" Fig. l and upon the same scale 'as Fig. l; y

Fig. 3 is a transverse sectional view of an alternative another application of the mixing device of Fig. l;

Fig. 4 is a transverse sectional view similar to Fig. 2 showing a square cross section plug; and

Fig. 5 is a transverse sectional View similar to Fig. 4 showing a triangular cross section.

Referring to Figs. l and 2 the mixture device A is provided with an inlet connection B to a faucet or other liquid source C. The mixing device has a central restricted venturi-like passage D and it has a side connection F to the liquid supply G which may be al liquid detergent, a liquid fertilizer or some other suitable liquid material.

On the connection F is positioned the handv cut-off valve H. The mixture device A has an out-let strainer l.

The most important feature of the present invention resides in the adjustable plug or insert K having the manual adjustment L. This plug K which is shown as hexagonal in cross-section in the preferred form of Figure 1 may have a square cross-section as indicated at M in Figure 4 or a triangular cross-section as indicated at N in Figure 5.

large outlet chamber 12 between which is positioned the lhighly restricted passage D and the more open passage The side of the body is provided with the opening 14 into which fits the upper nipple 15 of the side connection F. The side connection F is held in position by means of a shoulder 16 and it has a through opening 17 which receives the manual cutoff valve H.

The cutoff valve H has the enlarged head portion 18 and 19 and a central recess portion 20 which when positioned in line with the passageway 21 will permit full ow as indicated by the arrow 22 through the tube R and into the chamber 13. The nipple 23 will carry the ilexible and/or transparent tubing 24 which terminates in the inlet connection Q. It will be noted that the inlet connection Q has the portion 25 which tightly fits in the end 26 of the tube R and it also has the indentations 27 which hold the ball check S in position. The ball check S when it contacts the valve seat 2S will prevent reverse ow of liquid in the tube 24. The ball will be pressed .up against the indentations 27 when there is a substantial suction in the chamber 13 and when the valve H is in the position as shown in Fig. 1 with the recess 20 at the passage 21.

lThe section Q has the outwardly extending lingers 29 l which may be pried or spread from the material of the element Q so as to form the openings 30 which will permit ready ingress of the liquid detergent or liquid fertilizer or other liquid to be mixed. It will be noted in Fig. 1 that even though the device Q tits directly against the bottom 31 of the jar G the liquid will have ready entrance into the device Q and into the tube 24.

The inlet side of the unit A may have a tapered selfcutting thread element which will cut its own thread at 41 inside of the faucet connection C.

The end of the faucet connection C has a gasket 42 which may be pressed into the recess 43 formed between the body A and the conical element 40.

The outlet end 44 of the unit or body A has a threaded cup 45 which carries the strainer or Screen I. The important feature of the present invention resides in the adjustable plug having the spring element P which presses it against the camming nose 46 of the screw L having a thumb head 47.

By turning this screw L inwardly and outwardly it is possible to change the position of the plug K so that it Iis nearer the strainer I or farther away from the strainer I which surprisingly exactly controls the proportionment of uid, together with the venturi-eect of the narrow passage D and the wider passage 13.

In operation the plug which may be screwed into the inlet end of the unit A may thread itself into any faucet C as indicated with the gasket 42 forming a seal.

The plug K vmay be readily inserted after insertion of the spring P and then held in position by insertion of the thumb screw L. The strainer cup 4-5 may lastly be applied.

The side unit F may be pressed into the recess 14 with the valve H in position therein and then the hose R and Vthe unit Q will be applied. In operation, the hose R with the unit Q may be placed in any type of container or receptacle containing 'liquid detergent or liquid fertilizer.

The shape of the device Q will assureA a prompt supply of the liquid to the unit A and by manipulation of the hand screw L and the cutoff valve H, it is possible to regulate the spring which is passing through the strainer I to either clear aerated water or to a light, medium or heavy mixture of the detergent or other liquid with the Water.

By substituting a square cross-section M as indicated in Fig. 4 or a triangular cross-section N as indicated -in Fig. 5, a different range o-f proportionment may be achieved. It has been found that a wide variety of proportionment may be achieved in a measurable range of up to 1.2048 and this may be accomplished both by changing the position of the plug K or by changing the shape of the plug K as'indicated at M and at N.

Instead of an outlet strainer the outlet may also be provided with any suitable tubular outlet connection.

Various types of liquid detergents, fertilizers, chemicals and insecticides may be positioned in the jar G. The outlet connection J instead'of a strainer may also consist of a hose or pipe connection to a fixed or rotating brush arrangement or to a scrubber arrangement.

If desired, aerated openings may be positioned adjacent the position of a thumb screw L.

Normally by pressing the insert K close to the chamber 13 there is less suction and a lesser proportion of the added liquid. By moving the plug K outwardly a greater proportionment is obtained.

In the arrangement shown in Fig. 3 substantially the same unit is employed with correspondingly functioning parts being indicated by the same numerals and letters primed.

Referring to Figure 3 it will be noted that the faucet or pipe connection C is threaded as indicated at 70 to receive the tapped nipple 71 of the Unit A'.

The unit Q ts into a glass or container 72 from which the additional tiuid may be withdrawn. The adjustable plug K' may have varying forms and shapes as shown in Figs. 2, 4 and 5. It is thus apparent that the applicants have provided a novel mixer device which may be widely utilized for either household or industrial use to achieve predetermined mixing of uds or liquids and particularly to achieve various mixtures of detergents, fertilizers, insecticides and the like with water.

While there has been herein described a preferred form of the invention, it should be understood that the same may be altered in details and in relative arrangement of parts within the scope of the appended claims.

Normally the insert 40 will be used for a faucet end which is indicated as being horizontally directed at C in Fig. 1 while the other type of connection, as indicated at Fig. 3, will be used for a hose end indicated as being vertically directed in Fig. 3. However, any suitable tubular connection may be employed whether it be a faucet end or a hose end, whether horizontally or vertically directed.

The insert 40 by itself forms no part of the present invention but merely serves as part of the combination to enable the mixer device to be attached to a faucet end, such as indicated at C in Fig. 1, whether it be horizontal or vertical.

Normally, the device of the present application will under average conditions deliver two gallons of mixture per minute, as well as lesser proportions, which is far in excess of the usual mixer-suction device.

The chambers which receive the plugs K or K could bemade of predetermined polygonal cross section, such as hexagonal, octagonal or triangular, in which case the obstruction or the plug K could be made spherical or cylindrical to give the desired variable obstruction effect.

Having now particularly described and ascertained the nature of the invention, and in what manner the same is to be performed, what is claimed is:

A device for producing liquid mixtures comprising a mixing device adapted to be attached to one source of liquid, said mixing device including a body having an inlet chamber and an outlet chamber and a mixing chamber therebetween, said inlet chamber being connected to said mixing chamber by a venturi-like passage, a polygonal plug carried in the outlet chamber, said plug having a at face in the direction of said mixing chamber, a spring biasing said polygonal plug in the opposite direction, a strainer attached to the free open end of said outlet chamber, a screw mounted in said body for transverse movement relative thereto serving as an additional stop for said polygonal plug in the outlet chamber, and means, including a valved connection operatively connected to the mixing chamber of said body and a flexible tube attached to said connection, for supplying another liquid to said mixing chamber.
