July 14, 1936. E. ESSILEN POWDER MIXING DEVICE Filed Dec. 22, 1934 .Z ZW" patented July 14, 1935 UNITED STATES Fries Application December 22, 1934, Serial No. 758,844

In Germany November 2'7, 1934 3 Claims.

This invention relates to a powder mixing deyice having a rotatable brush and intended chiefly for home use for mixing slight amounts of powder, such as face powders of different color,

5 very quickly and simply so as to produce a mixture adapted to the complexion of the user.

To attain its object the invention provides for a rodlike brush movably and reversibly arranged in the removable cover of a cylindrical container for the powders to be mixed and corresponding in useful length to the diameter of the bottom of the container.

This construction makes it possible to put the powders to be mixed into the container without any impediment on the part of the brush and to start mixing immediately after the cover has been attached. Covering the bottom and part of the wall of the container, the brush takes up the powders lying on the bottom of the container, moves them to and fro by reversing motion and turns them over and over until a thorough mixture is effected within a very short time.

By way of example, the invention is illustrated in the accompanying drawing, in which Figures 1 and 2 are vertical sections of the device, showing the brush in different positions.

Referring to the drawing,the device comprises a container a for receiving the powders to be mixed and a removable cover b which overlaps the container a at c and is fitted with a bottom plate at secured to a flange e of the cover I). The bar 6 serves for centering the cover b and, in connection with the overlapping portion 0 of the cover b, effectively prevents the escape of powder bottom and extending with its part g into the container (1. and with its part II. into the bellshaped portion of the cover b. The case 9, it serves as a guide for a tube is having a bottom i, which is displaceable in the case g, h and influenced by a spring Z disposed 'in the case g, h. The tube It passes through the bell-shaped portion of the cover b and has a handle m for conveniently moving it downwardly against the pressure of the spring Z to bring it out of the position shown in Fig. 1 into the position according to Fig. 2 whereby a rodlike brush 0 rigidly connected with a spindle n is caused to carry out reversible motions. The spindle n has a cylindrical projection p which passes through the bottom 7'' of the case'g and serves as carrier of the brush 0. By means of the projection or pin 13 and the cam t the brush 0 is rigidly connected with the spindle n which is thus secured against axial displacement without being impeded as to rotary motion. Rotary motion is imparted to the spindle 12 through the bottom iof the tube k, which is constructed so as to correspond to the cross section of the spindle n, the bottom 2' thus forming a nut for said spindle. At its top end the spindle n carries a shell q which limits the uppermost position of the tube It, the downward motion of the tube It being limited by a collar r of the case h, for which purpose the tube la is provided with a jacket s which surrounds the case it and rests on the collar 2' when the tube is is in lowermost position.

The device functions as follows:

The cover 17 is removed from the container a, and the powders to be mixed are filled into the latter. Then the cover is put back and mixing started by pressure applied to the handle 111.. When the handle m is depressed, the tube 70 is moved down and, owing to the specially constructed bore of the bottom 2', causes rotation of thespindle 11. and thus of the brush 0. Reduction of the pressure applied to the handle m causes the spring I to push up the tubelc, the bottom plate i of the tube is turning the spindle n in a direction opposite to that prevailing during the descent, and continual up and down motion of the handle m will result in rapid to and fro motion of the spindle n and brush 0 whereby a thorough mixture of the powders is effected. The charging hole of the container 0. is large enough to permit instant removal of the mixed powder by means of a puff so as to dispense with filling the mixture into a separate container.

I claim:-

1. Powder mixing device, comprising a cylindrical powder container, a removable bell-shaped cover for said container, a rotatable rodlike brush, means for securing said brush to said cover, a bottom plate for said cover, a case carried by said bottom plate in the center thereof and extending partly into said container and partly into and through said bell-shaped cover, a vertically displaceable bottomed tube guided in said case, a rotatable spindle in said tube and case, a spring arranged in said case and adapted to act upon said tube, a handle at the tube end extending through the cover for moving the tube down against the pressure of said spring and thereby rotating said spindle, and means for rigidly connecting said spindle with said brush.

2. In a powder mixing device according to claim 1 a collar on the case and a jacket surrounding the tube and case and resting on said collar when the tube is in lowermost position to limit the downward displacement thereof.

3. In a powder mixing device according to claim 1 a cylindrical projection forming part of the spindle and extending through the bottom of the case and being rigidly connected with the brush, and a shell arranged at the top end of the spindle for limiting the upward displacement of the tube.
