' A This invention relatestoagitating mechainto a froth or lather instantaneously;

Another use to which the invention can be put is the mixing andv agitation of liquids and food and health compounds ormatter such as is commonly dispensed over the coun- The lnventlon may be put toany number of uses, and, in

view of the foregoing examples, it shall be.

understood that I do not wish to be limited as the functional and structural characterizing details of the invention give to the mechanism an exceedingly Wide range of adaptability;

One'important object of my the provision of means for causing a thread i of matter to-be treated-to be introduced to an to the said agitating process,- and inan automatic manner andwlth resulting thoroughness. Another important object of the invention resides in the provision of means for automatically heatingithe matter under treatment so that the discharging agitated matter will be warm, or the temperature, thereof raised to the desired degree according to: the use to which the invention is put.

lVith specific reference-to the use of the. invention as a lather producer, it is an object of my invention to provide new-and novel means for evacuating the free air from thesoap compound, before said compound is a subjected to an agitating treatment so that the lather, when produced, will be practi cally void of air. In other words, the means constituting an important part ofthe invention functions to produce'a lather which is not at all cellular as would be the case where the free air in the compound had not been exhausted before the agitatingv step is completed, as, and in such instance, it. manifest ly follows that the light cellular lather with its free air content breaks down as the filmy invention is from the discharge nozzleof the device;

Another important feature of my. in ven-.

a perfect state of preservation for many days and that its creamy consistency as against a light-cellular body structure results ,in-easew and comfort in shaving; also inconnection wlth the use of the invention as a lather pro- Tests prove that a lather formed in this manner will remain in ducer,--I am able through use of other i m-pore tant features of construction to provide a lather which is warm and ready for applica tion to the face of: the user asthe lather flows tion resides in the provision of means for restricting the: flow of soap compound to the agitating mechanism so that a. calculated quantity of soap w-illbe urged to the agitating mechanism in true or operative-time with the step of inducing thorough agitation. In this.

manner. a surprisingly small proportion of said soap compound is used at each opera;

tion. A perfect latherisprod'uced with the minimum amount of waste whatever.

Another object of the invention is to provide mechanism of this character which mayv be maintained in a sanitary condition.

A still further object of the invention is" to provide positively operating mechanism:

which will consist of a comparatively small number of parts, which are of exceedingly simple anddurable design. r Another object of the invention is to provide a device of this character which isalight of weight and capable of being. manuallyhandled with utmost convenience.

A further object of the invention is to soap and without any tinuous discharge of lather will be eflected I in time with the process of feeding the soap to the agitatingmechanism.

A further object of the invention is to provide mechanism adapted to be employed in connection with soap jelly and wherein means are provided to apply heat to jelly at charge terminal of the nozzle; and

Figure 5 is a section on the line 55 of Figure 1.

In carrying the invention into practice, use is made of a suitable vessel having a removable cover 11 whose central portion is formed with an aperture 12, the purpose of the latter being explained later. When used as a lather producer, the vessel is intended to contain a soap compound, preferably a compound of the consistency of jelly. I will relate the characterizing features of my invention with a compound of the above nature, because certain'peculiar actions will manifest themselves that will illustrate some of the advance steps to be accomplished in the art through use of my invention. However, and as previously stated, I am not to be limited to the use of the invention in the connection specifically recited, and it shall be understood that the invention can be used as a creamwhipper or as a beverage mixer or the like, and with marked success.

The cover 11 is upset to form a cavity 13- for an electrically driven motor 14 whose armature shaft 15 is disposed vertically and axially of the vessel 10. Its lower end is formed with a kerf 16 in which is fitted the fiat extension 17 of a helical dasher or agitator 18. The base of the motor is provided with a depending boss 19 having an external thread 19a which detachably receives the internalthread of a chamber 20. The said chamber has an apertured seat 196 which acts as a bearing for the axial stub shaft 21 of the agitator 18, the said stub shaft carrying the fiat extension 17. The said seat 196 is adapted to fit tightly against the lower face of said boss 19, thereby acting to seal the motor against entrance thereto of liquid from the chamber 20.

The helical agitator 18 is relatively long. By that I mean that it is almost co-extensive with the depth of the vessel 10 so that it extends about to the bottom thereof. The

lower end of the agiator is provided with a shaft 21 mounted to freely revolve in a step bearing 22 in the upper face of a nut 23. This nut has a lateral flange 24 which serves as a shelfor rest for the lower end ofashell 25. This shell fits over the said chamber in concentric spaced relation thereto and its upper end receives an enlargement 26 of said,

The nut 23 functions to hold the chamber. respective parts correlated normally and to enable one to separate or knock down the parts'when repairs are needed.

In the space between the chamber 20 and said shell and wound about the former lowed between the parts to allow of freedom of rotation of the'agitator.

The nut 23 is provided with an aperture 28 which opens into the chamber 20 and into the vessel 10, respectively. The size of the aperture is calculated so that a fine stream or thread of matter may be drawn intoithel chamber from the vessel by suction induced in the regular functioning of the agitator and the matter subjected to the direct action of the agitator. When soap jelly is used as a lather producing vehicle, the chamber 20 penetrates the mass. The lower end of the chamber is intended to be covered by the soap mass at all times, with the small intake aperture of the nut 23 in direct contact therewith. In this manner, I am able to accomplish aeration of the soap as it enters the chamber ready to be acted upon by the agitator, and the lather which results from the functioning of the described instrumentalities is paste-like, rather than highly cellular or light and fluffy as would be the case where air is permitted to enter the agitator with the soapy matter. In the latter example, the lather breaks down prematurely; is short lived and frequently rendered unfit for use, while, and by excluding the air as stated herein, I am able to produce a lather which may be kept indefinitely after it-is made.

The chamber 20 and the shell 25 are formed with apertures 29 and 30, respectively, which are in horizontal alinement and which receive the inner end of a nozzle 31. The outer end of said nozzle extends outside of the cover 11, which is preferably curved downward in order that it may be made to discharge its flow into a cup or suitable receptacle, not shown.

The operation of the machine has been explained so that no further discussion need be necessary. But it is desired to emphasize the fact that by taking the soapy matter thread or the thin stream into the direct presence of theagitator, a great saving of soap is made possible and that, in addition thereto, a maximum quantity of lather is produced from a minimum quantity of soap. By the radiant action of heat the soap jelly is heated at the source or at the small orifice 28 which acts to liquefy the soap as it entersthe chamber 20. It is also important to note that the lather flow at the discharge nozzle operates synchronously with the step of introducing the soap to the action of the agitator, and that by drawing the soap into the chamber 20 by induced suctionand causing it to move upward and longitudinally of the chamber 20, the lather when delivered is of a warm temperature ready for application to the face. It is also important to note that the operation of producing the lather is instantaneous.

I claim:
