Be it known that I, AUGUST VoGEs, a citizen of the United States, and a resident of Chicago, Cook County, Illinois, have invented a certain new, useful, and Improved Method of' Preparing Soap for Use, of which the following is a specification.

There is still some controversy as to the exact causes and reactions that result in the cleansing action Vof soap, but there are two generally accepted theories advanced as to the cleansing properties of soap. One such action is the emulsifying action, for it has been found that when an insoluble oil, such as kerosene, for example, is shaken in water it is divided into a large number of minute globules, which, however, so soon as t-he shaking action is stopped, begin to run together and finally unite to form a layer of the oil separate and distinct from the body of the water. If, however, a dilute soap solution be shaken together with an insoluble oil, such as above stated, the minute globules formed donot run together after the shaking action has stopped, but on the contrary, remain permanently suspended in the solution, the reason for this being, that each minute droplet or globule of oil is 'surrounded entirely by a covering of the dilute soap solution and the droplets are thereby prevented from contacting one with the other and thus running together. It is this surrounding action of the dilute soap solution when applied to material having a greasy or oily substance therein that permits of the article to be cleansed by wash ing out the grease particles. The solution,

in order to do its best work, should be a dilute solution.

Another cleansing action attributed to soap is that of the adsorption of colloidal matter, for example, when a solution containing a colloidal substance is shaken with the nely pulverized charcoal, the colloidal substance adhere to the surface of the powder.

In other words, there is a tendency tocol hesion between the colloidal in the soap solution and the particles of a fine powder. As the articles of ne dirt are'comparatively few in the article or surface to be cleansed, as compared to the soap solution, the colloidalI particles carry off the dirt. That is to say, the dirt is removed by adsorption into the soap solution.

vWhether the above or other theories are the true explanations of the cleansing act1on of soap I have discovered that it becomes possible to cleanse a much larger surface with a much smaller quantity of soap when the soap is broken up into very minute particles and that the general action of cleansing is greatly facilitated, and made much more thorough.

It is an object of my invention to provide a method whereby it shall be possible to make a given quantity of soap per-form more work as a cleansing agent, and whereby it shall be possible to cleanse more rapidly, more thoroughly and more conveniently.

Another object of my invention is to provide a method of preparing soap for use in such manner that it shall be possible with a given number of .lavatories in a large factory, to enable a larger number of workmen to wash within a given time.

My invention consists `generally in the method whereby the above named objects, together with ot-hers that will appear hereinafter, are attainable and my invention will be more readily understood by reference to the accompanying drawings' which illustrate what I consider at the present time to be the bestembodiment thereof.

In said drawings, Fig. l, is a sectional elevation of a wash basin equipped with apparatus for producing my invention. Fig. 2, is a front elevation of a wash basin and apparatus shown in Fig. ,2.

My invention may be carried out in a number of different ways and by the use of widely diEerent apparatus, but inasmuch as' the invention probably finds its greatest use in large manufacturing establishments where it is customary to provide liquid soap for washing purposes, I shall describe my invention in conjunction with liquid soap and also as applied to an ordinary troughlike wash basin such as are usually found in factories.

Referring to the drawings; 1, represents a trough-like wash basin provided with a plurality Iof spaced faucets 2, enabling the basin to accommodate a number of people. Inthe present instance, I hang upon the back plate 3, of the basin a shelf-like member, 4. by means of spaced supporting members 5, thereon. The shelf-like member 4, as here shown is provided with a basin-like portion, 6, upstanding from which will be provided` with an outward yextension 8,

` which forms asupport yfor a jar orreceperal; construction to.y an airbrush. v That `is fwtosayy it isy provided with acover, 11, :on f f which is :supported a gun, 12, yhavingy anair i rl() Y' at the other.: :The connection 15, isa pipe f v such f that` when air is :admitted to the bar-y yrelofthe gunasby'pressingthetrigger,` o o o o l 16, the liquid soap 10,inthejar,l9, is forced f upwardly through vthe vertical pipe, :17,and

Not only is it possible by this means to wash or cleanse more rapidly, but it is also possible to cleanse more thoroughly and with the use or but a fraction of the soap required ywhen soap forro;y
