LATHER MIXER Filed March 26, 1932 upon a soap bod Patented June 20, 1933' imnvm BOLSTAD, or won'rnmerozr, mason LATHEB KIXER Application filed larch 2a, 1932. Serial 10. comes.

This invention relates to improvements in mixing devices and pertains articularly to a devlce for mixing lather or. shaving I pur oses.

T e primary object of the present inven tion is toprovidea device for quickly furnishing a suitable lather for use in shaving and at the same time makin it possible for the user to provide himsel with just the right amount of lather for the shaving operation, thereby-conserving the soap.-

, Another object of the invention is to provide a lather mixer which provides warm water for use in forming the lather so that i 35 the lather will be suitably warmedwhen withdrawn. 1

A San further object of the invention is toprovide a novel lather mixer having an electric motor operated brush which rotates within a suitable receptacle, thus rapid y forming a heavy lather which is drawn oil from 'the receptacle through a suitable discharge 'opeiiin The invention will be. best un erstood from a consideration of the following detailed description taken in connection with the accompanying drawing forming part of this specification, with the understanding, however, that the invention is not con- 39 fined to any strict conformity. with the showing of the drawing but may be changed or v modified so long as such changes or modifications mark no material departure from the salient features oi the invention as expressed in the appended claims.

In the drawing Figure l is a view partly in elevation and partly in vertical section through the preferred form of the lather mixer embodying 4 the present invention;

Figure 2 is a view partly in vertical section and partly in elevation of a modified form of mixer. Y

Referring now more particularly to the 4 drawing wherein like numerals of reference indicate corresponding parts throughout the several views, the numeral 1 indicates a vertically disposed cylindrical receptacle mounted upon a base 2 which has an upstanding threaded flange upon the top thereof as indicated at 3, which threads into the lower end 'or bottom of the receptacle toclose the same;

The wall of the receptacle is provided at a suitable elevation with a lather draw-ofi spout 4 which is closed at its outer end by a valve of any suitable character, the valvehere shown comprising a sliding disk or plate 5 which is normally held in position across the mouth of the nozzle by a sprin 6 mounted in a suitable holder into whic the disk is pressed when the nozzle is 0 en.

In the upper portion of the receptacle 1 are two spaced partitions 7 and 8 which form the chambers 9 and 10. The chamber L 10 is lined with a suitable insulating material as indicated at 11 and within this chamber is mounted an electric resistance heating coil 12, the terminals of which are connected by suitable wires-13 with a cable 14 upon the outside of the receptacle, which cable has one end connected with a suitable plug '15 ior coupling it with a source of. electric current su ply.

The upper chamber 9 of the receptacle is 7 provided to contain water and this is discharged into the lower part of the receptacle or chamber 16 in which the lather is formed, through a tube 17 which leads fromthe Wall 7 which-forms the bottom oi the chamber 9, through the chamber 10 and into the upper part of the chamber 16, as illustrated. Any suitable means may be employed for controlling the flow of water from the chamber 9 through the tube 17 and there ishere 8 illustrated a needle valve 18 which is shifted by a suitable screw 19 under the control of a handle 20 which is positioned above the top of the receptacle 1, the screw 19 being threaded in a suitable sleeve in the top 00 of the receptacle. a

A suitable spout 21 is provided to facilitate the introduction of water into the chamher 9.

Mounted upon suitable brackets such as those indicated at 22 upon the top of the receptacle 1, is an electric motor 23, the armature shaft of which is vertically dis,- posed and either extended to form the shaft 24 or having the shaft suitably coupled V thereto. This'shaft 24 extends downwardly through suitable bearing sleeves, into the lather chamber 16 and upon its lower end is a ke 25 which ositions in a suitable key way 2 in the we lot a tube 27 into which the shaft extends. This tube 27 is connected with the top of a circular brush 28, the

; mitted relative to the shaft.

The cable 14 may be provided with a switch 30 at a point between the heating coil 12 and the motor so that the motor may be started or stopped without interfering with the operation of the heating coil.

. In Figure 2 a slightly modified form of the invention is-illustrated wherein the receptacle 31 constitutes. the lather chamber and this is mounted upon a suitable base 32 and closed by a removable cap 33 at its lower end. The motor and brush structure for forming the lather and the draw-off faucet or spout and valve therefor are the same as shown and described in the preferred form. 7

Mounted upon the base 32 beside the receptacle 33 is a casing 34 which en ages the receptacle 31 at one side and whic has its bottom open asat 35 while its top is formed to provide a receptacle 36. The top of this receptacle has a filling opening 37 therein and a pipe line connects the bottom of the receptacle with the lather receptacle 31, as indicated at 38, which line is controlled by a suitable valve 39.

The water within the receptacle 36 is warmed and maintained in such condition by the use of an incandescent lamp 40 mounted in a suitable manner in the casing 34 beneath the water receptacle. The structure here shown for the support of the'lamp com rises a bracket 41 removably attached to t e wall of' the casing and carrying a socket 42 into which the base of the bulb is threaded.

From the foregoin it will be readily apparent that with the evices herein described a suitable heavy lather may be easily and quickly worked up in either of the lather receptacles by introducing a slight amount of water into the chamber containing the soa and then running the motor connected wit the lather brush, for a suitable period of time. Upon o ning the valve 5 the lather will flow from t e receptacle into a suitable receiver from which it may be clipped for use. It will thus be apparent that the lather may be transmitted directly from themixer hibits the use of the same shavin brush by barbers for lathering the faces 0 different customers. The device, therefore, has advantages from a sanitary point of view as well as an economical one.

As one becomes accustomed to using the lather mixer it will be possible to judge the approximate amount of lather required for a shaving operation and thus no more than the required amount need to be drawn from the receptacle.

Having thus described the invention, what is claimed is 1. A' lather mixer comprising a recep-r tacle,'a cover removably attached to an end of the receptacle, an outlet for the receptacle, a rotatable shaft dis osed vertically in the receptacle and exten ing to the exterior thereof, a brush member having a sleeve, the brush being within the receptacle and having the sleeve slidably receiving an end of said shaft, means preventing turning of the sleeve on the shaft a liquid chamber having communication with the receptacle, means for warming the said chamber, and valve means for regulating the flow of liquid from the chamber into the receptacle.

2. A lather mixer' comprising a receptacle having a removable bottom, an outlet for the receptacle, means to provide two chambersin the upper part of the receptacle, the uppermost one of said chambers being 'de signed to contain a liquid, a heating element in the other of said thambers, means for conducting liquid from the liquid chamber into the lower part of the receptacle, means for controlling the flow of liquid into the receptacle, an electric motormounted upon tacle, a casing adjacent the receptacle formed in its upper art to provide a liquid chamher, a valv pipe connecting said liquid chamber with the receptacle, and heating means within the casing beneath said chamber.

In testimony whereof I hereunto affix my signature.
