'l Claims.

This invention relates to improvements in a soap and water mixer and more particularly relates to a dispenser from which one or more concentrations of soap solution may be drawn olf at the same time.

One of the objects of this invention is to provide a soap dispenser in which the soap is spaced from a part of the container to form mixing chambers into which water is introduced for the purpose of creating a soapy solution which may be drawn off as desired.

Another object of this invention is to provide a multiple chamber soap container into which water is conveyed in diierent proportions to the different compartments and for different periods of contact with the soap such that different concentrations of soapy solution may be formed in the respective compartments.

Another object of this invention is to provide a soap dispenser which will furnish two different qualities of soap solution from a mass of paste or solid soap enclosed in a container such as a keg, barrel or drum, such different soap solutions being withdrawn from the same end of the container and so that one solution of one concentration may be mixed with the other solution of another concentration to give the desired strength.

Another object of the invention is to provide a barrel of soap with the soap spaced from the ends and with a water tight inclined conduit supported by and extending through the soap so that Water sprayed against one end of the soap mass will form a relatively low concentration of soap and other water from the spray will pass through the soap to act on the other end of the mass and will form a more concentrated solution.

Further objects and advantages of this invention will appear from the following description thereof taken in connection with the attached drawing which illustrates a preferred form of embodiment of my device, such drawing being a central vertical section taken through a barrel and showing the interior connections partly in section.

Soap dispensers of the type illustrated are frequently used in garages and in other places where different concentrations of soap may be desired. In such constructions the container is usually a barrel, drum or keg which may have a capacity of soap varying from fty to one thousand pounds or more or less. Water is introduced into such containers to make the solution, but in the previous constructions it has been substantially impossible to continuously regulate the concentration as it would vary with the rate the soap was used. It was also substantially impractical to have more than one concentration available at the same time.

In the drawing which is merely illustrative of one form of device, in which these objections are overcome, the barrel l0 is shown filled with soap 12 which may be in a thick paste or solid form as desired. The soap 12 is preferably held in position by reticulated screens 14 slopingly mounted with reference to the axis lof the barrel, which form separate chambers spaced from the walls of the barrel and yet expose the soap as necessary. When the barrel is rst put into use the bottom 16 of the barrel and the soap supported by the lower reticulated screen 14 forms a soap chamber A, and the head of the barrel 18 and the soap retained by reticulated screen 14 forms a second soap chamber B. It is to be understood, however, that it is not essential that the chambers be formed by this means and that as the soap is dissolved the chambers in each end become larger and extend beyond the screens 14.

The head ofthe barrel 18 is provided with a water connection 20 and the interior of the barrel preferably has a spray or similar water dispersing device 22. The construction is such that when the water is admitted into the chamber B it will impinge upon the inclined wall of soap and will wash away and dissolve a certain portion of the soap. The soap solution in the chamber B then flows immediately down the surface of the reticulated screen and if withdrawn promptly its concentration may vary from 0.2% to 2% of soap. This solution may be withdrawn through the spigot or other valve 24. The relative location of the spigot 24 is not a feature of this invention but it will be placed as near the lower level of the soap solution as possible for proper drainage.

The soap preferably has a water tight tube 26 suitably inclined through it and projecting at each end through the reticulated screen and in the construction illustrated the upper end of the tube 26 is placed adjacent the spray at the top of the chamber B so that part of the spray of water from the spray head 22 will run down the pipe 26 and into the chamber A. The diameter of this tube may be ofsuitable size such as one-half inch to 2 inches as desired and it is preferably inclined at such an angle that the water will flow into the chamber A by gravity.

The concentration ofthe soap solution obtained at A is dependent upon the time that the Water or solution is allowed to stand in contact with the soap in the dispenser and may vary from 0% to 40%. In the use of the dispenser, however, it is intended that the soap solution shall be drawn from the chamber A only at spaced intervals and after the solution has stood long enough to become fairly concentrated.

A second conduit 28 may also be placed through the soap to be connected with the spigot or valve 3,0 for withdrawing the soap solution sov 01T at the same end of the barrel. It is obvious, however, that if desired, the spigot 30 may be driven into the barrel at the bottom end in direct contact with the body of soap solution in the chamber A or in any other connection may be made to Withdraw the soap solution.

The pipes 26 and 28 carry the water through the soap without direct contact so that large holes are not made in the soap through 'the center of the mass before the end of the soap is worn away. With such construction the amount of solution may be more carefully regulated and there Will be a more uniform wearing away of the soap. It is also to be noted that although a relatively low concentrate of soap is produced at one end and a relatively high concentrate of soap is produced at the other end, it is possible to combine the mixtures and obtain any intermediate quality of soap concentration as desired. n

The screen 14 which retains the soap should be suiiiciently ne to prevent passage of solid soap therethrough which would clog the outlet. The spray and -discharge spigots are preferably placed at the same end of the container to permit easy operation of the device. A suitable stand may be provided to hold the barrel in horizontal position.

Although the device has been particularly described in operation with soap, it is to be understood that any other soluble mass may be suitably placed in such a container and it will similarly afford different concentrations of solution simultaneously which concentrations are subject to control for uniform quality.

While I have shown a preferred form of embodiment of this invention I am aware that other modications may be made therein and I therefore desire a broad interpretation of my invention within the scope and spirit thereof and within the scope of the appended claims.
