2 Claims. (01. 259-4) This invention relates to an automatic mixer and more particularly to a continuous operation.
The present invention provides a method for mixing materials in predetermined proportions mixer adapted for andit is primarily intended for the treatment of materials to be used in the manufacture of cosmetics and in preparing pigments or other coloring matter for general use, and also to suit special requirements.
.It is among the objects of this invention to utilize a regulated stream of compressed s,such
as air, moving at a high speed and un er great compressional energy for mixing ma rials in predetermined proportions to enable one to quickly obtain the desired tints wherein the pigments are mixed very finely with the dry base and are fed continuously into a mixing chamher by {regulated streams of compressed gas 10 maintained at a constant speed.
It is also an object of the invention to utilize a regulated stream of compressed gas, for introducing the different powdered materials into the mixing chamber and to provide regulated mate- .5 rial-introducing streams of compressed gas in an air-float mixer which shall constitute a part of the general material agitating or mixing means.
In order to-obtain the full range of tints of cosmetics and other materials, a variety of coloring is necessary. It is a further object of this invention to enable one to quickly obtain the desired tints in an air-float mixer which is easily convertible to suit different requirements.
It is a still further object to provide an improved apparatus for carrying out the above process which will be capable of'operating continuously, wherein the base or coloring material will be well mixed and to ensure against the formation of lumps, to bring about afine product heretofore impossible to obtain .by the use of existing equipment, by giving the base and coloring matter a perfect air-float mixing at a high rate of output,and which shall be obtained in a device of simple constructiomwhich is easily and quickly assembled and disassembled and therefore easy to maintain in sanitary condition wherein sterilized, germ-free materials may be obtained during the mixing process without additional equipment. However, the process is not so limited to the use illustratively disclosed herein but may be adopted whenever it is desired to accomplish the same or similar results in mixing by compressed air powdered materials which are intended to be used for other similar purlocking the same in place.

Fig. 5 is a fragmentary, enlarged vertical,
cross-sectional view of the upper portion of the' apparatus showing particularly the driving arrangement for the material feeding means;
Fig. 6 is a horizontal cross-sectional view taken through the mixing chamber;
Fig. 7 is a fragmentary, side elevational view .of a somewhat modified formof device for adjusting the position of the containers for the material;
Fig. 8 is a vertical, cross-sectional view taken along the line 8-8 of Fig. 7; and
Fig.9 is a view similar to Fig. 6 showing particularly the arrangement of heating elements chamber 2 fitted thereon with doors 3 allowin access to the interior thereof. A mixing chamber 4 of annular shape is secured'to the top of enclosure 2 and a cover 5 therefor is hinged at 6 and is provided with means 1 for latching or formed integrally with said cover.
A pair of feed hoppers 9 and In on opposite sides of ,chamber 4 are provided with conduits II and I 2 respectively communicating with the open bottoms l3 thereof and connecting with pipes l4 and I5 which enter opposite sides of chamber 4. Angular ducts It and I1 respectively cause the mixture of gas and material entering through pipes l4 and I5 to have a swirling motion within chamber 4.
A gas supply passes through valve I8 and pipe l9 and thence through branches 20 and in through openings 2| in the bottom of chamber 4. An annular partition 22 within chamber 4 provides an annular passageway for gas entering in through openings 2|. Blocks 23 at opposite sides thereof together with ducts l6 and I1 dividethe same into independent gas chambers. Each of A gas exit pipe 8 is horizontal beams or the like 32.
such chambersds provided with an opening 214 angularly placed and assist in the flow of material and cause intimate mixing thereof. From pipe I 9 branches connect to conduits I I and I2 to supply gas from a single source for both the transporting and mixing operations.
A central exit opening of annular shape 26 is provided by means of central member 21 and a pipe 28 depending from pipe 8 enters member 21 and provides a centrifugal separator causing the gas to pass upwardly through pipes 28 and 8.
The material deposited in member 21 falls into receptacle 29 within the housing 2.
Projecting upwardly from the base I are standards 30 and 3| united at their upper ends by The arrangement provides an opening 33 whereby the cover 5 may be conveniently retained in open position, as shown more particularly in Fig. 3.
A horizontal pipe 34 is fixed in the framework so formed having a downwardly extending elbow 35. A. pipe 36 of. larger diameter than pipe ,8 and provided with a set screw 31 allows a connection between pipes 8 and 34 when cover 5 is closed, as shown in Fig. 2. When the cover is to be opened, screw 31 is loosened, pipe is telescoped over pipe 8, thus providing sumcient space for quickly and conveniently opening the cover.
On top of the framework is a plate 38 to which a motor 39 is fixed at a central portion thereof. It is connected. to a gear reduction system 40' and carries a friction wheel 4| at the extreme end of the motor shaft. A pair of containers 42 and 43 on opposite sides of friction wheel 4| as shown in Fig. 1, are provided with'covers 44. In the bottom of said containers are screw conveyers 45 and 46 respectively for feeding materials therein into horizontal pipes 41 and 48 respectively and thence into verticalpipes49 and 50 respectively. Sleeves. 5| and 52, preferably of flexible nature such as rubber hose, fitted over the respective pipes 49 and 50 are provided with set screws 53. I
At the inner ends of conveyors 45 and 46 are a pair of discs 54 and 55 respectively, in parallel relation and contacting with friction wheel 4| which is located between the same. Bushings 56 and 51 are provided over said wheels 54 and 55 for sliding movement. A pair of springs 58 and 59 are fitted over the respective bushings as shown in Fig. 5 whereby wheels 54 and 55 are continually forced into frictional engagement with wheel '4l. Cover sleeves 60 and GI are usually provided for protective purposes.
Provision is made for changing the relative speeds of conveyors 45 and '46 whereby the relative amounts of material being fed and mixed .may be changed at will and within wide limits.
To accommodate this, mechanism is provided whereby containers 42 and 43 with their associated mechanisms may be shifted bodily relative to member 39. There are provided a pair of arms 62 and 53 for respective containers having notches 64 along the lower edge thereof. Depending members 65 and 65 from the respective containers have openings 61 therein of a size and shape as to closely accommodate arms] 52 and 53. Set screws 68 are provided in the bottom of members 65 and 66 and adapted to set into any desired notch 54. It will be seen that by shifting one or both of the containers the relative position of friction wheel 4| withrespect to the discs 54 and 55 may be used to change the ,rate of revolution of the conveyors.
vIn some cases it may be desirable to allow vertical movement of the containers and also to provide a different means for shifting .the
same laterally and this is provided for in the modification shown in Figs. '1 and 8. Secured to the beam 32 is a sleeve 69 having a bar Ill slidably mounted therein with a set screw ll leading into an opening in depending member 55 adapted to accommodate arm 12 which instead of being provided with notches, is provided with a scale 13 whereby to gauge the desired position of the container in question. Set screw I4 allows a fixing of the container in its adjusted position- Member Y tion, Ser. No. 278,513, filed June 10, 1939. The
bottom I8 of chamber 4 is provided with two annular sets of heating coils located below chamber 4 but secured'to plate 13. Leads 35 and I! are connected to a suitable source of power whereby any desired regulated amount of heat for sterilization or other purposesemay be supplied.
Although I have described my invention setting forth a single complete embodiment thereof and, slight variations of the construction, it will be apparent that many other changes may be made in the details without departing from the spirit of the invention. For instance, the openings of the gas inlets of the mixing ch ber may be of any number as the size of the mixing chamber may require, but they are to be placed so that their angle will permit and tend to deliv the materials forward into the adjacent gas s m. The speed of the material introducing streams may be varied by manipulation of gas inlet valves so that the flow of compressed gas may be increased or decreased as the different materials may require, and there may be provided a separate valve for other gas inlets while the pressure of the gas stream flow through the mixing chamber may be regulated from'the main valve. The gas streams may also be supplied from the bottom by utilizing an arrangement in the shape of a star so that the streams of the outlet openings are directed upward and forward. This arrangement may also be used in combination with or instead -,of an arrangement where the inlets andopenings are provided with means to utilize a stationary or exchangeable upper plate. There also may be provided a series of projections on the bottom plate of an angular shape having suitable gas inlet openings so that the gas supply may be continuous and strong enough to move the material forward under pressure as may be required. Of course, there is no set limitation as to the exact pressure required, as that largely depends on the size of the mixing chamber, the material to be used, its granular or particle size and weight and also on the amount of material fed into the chamber in a given time.
