UNITED STATES; PATENT OFFICE commons s'rsmuznn Samu-El Kali-Shalom, autu n. Y. Application June 10, 1939, Serial No. 278,513 12 Claims. (01.21-93) This invention relates to an automatic sterilizer and more particularly to a sterilizer adapted for continuous operation.
The present invention provides a method and an improved means for destroying small organisms and bacteria, and it is primarily intended for the treatment of materials to be used in the" manufacture and preparation of cosmetics: but it is also applicable to many other materials, which either for purposes 01' preservation or as a sanitary precaution or other similar purpose in which it is desirable to destroyer inhibit the growth or development of deleterious germs or any living organism, by utilizing fluid pressure greater than the normal atmos Tieric pressure.
- Materials used in the manufacture of cos metics which contain bacteria, spores or other living organisms are harmful and tend to discolor the skin and in many cases cause the skin to become thin, wrinkled, dry, inelastic, and sub-' J'ect to uncomfortable irritation.
Therefore, the primary objects of the invention are to provide an improved method and means which shall be adapted for the sterilizing of substances which consist, in subjecting such materials and substances to direct air pressure; to provide an improved method whereby the particles of the different materials and substances are fed into the system in mass. form but are presented to be sterilized individually and forced into an air stream moving at a high speed and under great compressional energy; to provide an improved method and means whereby materials of different classes may be sterilized and freed of any living organisms which may .get eventually into the pores of the skin and cause serious consequences; to provide an imdirection or in a direction opposite to each other within the sterilizing chamber, so that the currents of materials to be sterilized shall sweep one against the other; to provide an improved apparatus having a plurality of air streams arranged -to operate in the-same or opposite directions to produce a more efficient sterilizer; and
proved method whereby the difierent materials used in the manufacture of cosmetics are not subiected to any discoloration while being sterilized; to keep the sterilizing apparatus at an even temperature and at a temperature most suited for a given material; and to provide an arrangement whereby the material shall be iedcontinuously at a predetermined rate, so that the sterilizing chamber shall not be overfilled at any time. I
It is the further object of this invention to provide an improved method of sterilizing materials used in the manufacture of cosmetics in which definite currents of compressed air are set up continuously in such a manner that those high speed compressed air currents will tend to remove from the inner surface of the walls of the sterilizing chamber materials adhering thereto, thus increasing the efllciencyand thoroughness of the sterilizing apparatus.
It is also an object 01 this invention to provide an improved process in which the steriliz-' ing chamber is arranged so that the air inlets di ect the flow of co press d ai i t e so e g ge ent wi h one for carrying out the above processes which will be capable oi operating continuously at a high rate of output which shall be of simple con-- struction, easily and quickly assembled and disassembled and therefore easy to maintain in a sanitary condition, and wherein a mixture of materials may be obtained during sterilization.
The process and apparatus is not however limited to the use illustratively disclosed therein but may be adapted whenever it is desired to. accomplish the same result and bringing about the destruction of bacteria and microorganisms in materials used for other purposes.
In the accompanying drawings constituting a part hereof, in which like reference characters indicate like parts,
Fig. 1 is a front view of an ing my invention:
Fig. 2 is a side elevational view thereof, some parts being broken away for clearness;
Fig. 3 is a view similar to Fig. 2, showing still other parts broken away for clearness, and showing the apparatus in a different operative position:
'Fig. 4 is a horizontal cross-sectional view taken through the sterilizing chamber;
Fig. 5 is a fragmentary, enlarged, vertical crosssectional view of the apparatus; and
Fig. 6 is a view similar to Fig. 5, but taken from a different portion of the apparatus.
The apparatus comprises the base i having a pair of extensions 2 thereon, provided with ribs or tracks 3.' Mounted on said tracks are sets of wheels 4 mounted for rotation on axles 6 held in bearings 8, which in turn are secured to plate 1 constituting part of sterilizing chamber 8. Through this arrangement, the mixing chamber maybe shifted from below the top or I cover 26 when desired, to facilitate cleansing oi the interior of the mixing chamber. A cover plate 9 removably secured to the base i allows access to the interior thereof. a
apparatus embody- A-standard l0 securedto the base I extends upwardly above chamber .8 terminating in a horizontal overhanging arm i i within which a vertical screw I 2 is mounted. A beveled gear !3 secured to screw 12 meshes with similar gear N on horizontal shaft is held in hearing it and terminating in wheel i'l having handles I8 thereon for manual manipulation of the screw H. The screw I2 is threaded into horizontal arm i9 having a yoke 20 at one end thereof in sliding vertical bar 2!. the opposite end has a depending portion 22 terminating in pivot 23. A crank'havins' arms 24 and 25 is .mounted on said pivot. Arm 2! is secured to cover 26 of sterilizing chamber 8. Arm 241 has its free end beveled an contacts with similarly beveled portion '21 of block 28 secured to standard i0. 1 Y
When it is desired to lift the cover 26 from chamber 8, the hand grips l8 are manipulated to turn the wheel 11, thus turning the screw 12 thus beginning to raise cover 26. By reason oi the beveled portion 21 and arm 24, the upward movement of bar i8 causes a tilting of cover 26, as. shown more particularly in Fig.3. This sterilizing temperature the temperature thereof being largely dependent upon the materials being mixed and sterilized, and for this. purpose there is secured to the underside -of member 1 constituting the bottom of chamber"! remember 81 forming an additional chamber. A series of electric-heaters 68 of any suitable type are secured therein by screws 69 and connection 10 10 whereupon arm is is drawn vertically upward,
renders the interior surfaces on cover 26 read-- 3'! and 38 of chamber 8, as more particularly shown in Fig. 4. A series of openings 38 in the outer wall of the sterilizing chamber ,angularly' placed, allow thegas entering through openings 35 to pass through the sterilizing chamber in a therefrom lead to a source of electrical energy. Generally, heating elements 68 are suitably spaced underneath the entire extent of chamber 8.
The hoppers 42 may be mounted for movement in order to place them in a position so that they will not interfere with the lifting of cover 26 as shown in Fig. 3. For this purpose, there are provided a pair of brackets ll having at their extreme ends vertical pivot rods I2 on which are mounted bars I3 which in turn are secured to the bases 43 of hoppers"; Set screws are provided whereby upon the loosening thereof bars 13 may be swung outwardly carrying hoppers 42 with the attached pipes 5| therewith. The cover 28 may be provided with suitable insulating material as for example, a. layer of cellular asbestos 14 or the like, such insulating material may be provided about the entire cover, if deswirling movement. Similar openings 4| in the inner wall of the sterilizing chamber allow gas from openings 38 to pass into the sterilizing chamber with a similar swirling motion tending to uniformly distribute the currents of gas and material being sterilized.
There .is provided a pair of hoppers." mounted on blocks 43 having a shaft 44 carrying an agitator 45 within the same and immediately below said hoppers. A gear 46 on shaft 44 meshes with gear 41 which is in turn secured to gear 48 whereby the train of gears may be driven. Shaft 49 rotated by gear 41 has a screw conveyor 50 secured thereto for taking material from hoppers 42 and feeding the same into pipes 5i. Said pipes communicate with feed hoppers 52 allowing material to enter chamber 8 at points 53 near the outercircumferenceof said chamber. At the inner circumference of said chamber there is an exit opening 54 communicating with separator 55 adapted to impart a cyclone action to- .by the weights 62 hold the container 51 in operative position and by the raising of said weights, the said container may be readily removedfor emptying the contents thereof.
The driving means for gearing 46-41-48} may sired. Briefly, the operation of the improved apparatus is as follows: 7
The materials to be mixed are delivered into the mixing chamber from the hoppers 42 by the feed mechanism described and more particularly disclosed in Figs. 5. and 6. As the materials are fed into the mixing chamber, air or other gas under pressure is admitted through pipes 35 and 36 into the annular portions 31 and 38 of the mixing chamber. From thence the air passes in streams through the angular openings 39, as indicated by the dotted lines in Fig. 4, to swirl the materials round and round within the cham-- ber 40 and thoroughly mix the same. During the time that this mixing operation is taking place, the temperature within the chamber is maintained at a suitable high level, according to the be directly connected to the train'as shown in Fig. 5, but preferably reduction gearing isepro' vided as shown in Fig. 6. A set of gears G3-.-64 1 is provided on sleeve la-that is loose on shaft 44, the gear filmeshing with gear 48 and gear 64 meshing witlij -"gea'r 55, the latter'beingjdirectly connected to d ve motor 68. Change speed gearing maybe provided at this pointL is kept at a suitable sterilizing" chamber 8 nature of the materials being mixed and sterilized, so that the materials being mixed are simultaneously heat-sterilized.,"I'he mixed and heated materials descend through opening 56- and into the container 51 while the air or gas under pressure leaves the apparatus through I therein and a predetermined time elapse, sufficient to give adequate sterilization and then removed from the chamber and separated from the gas used. .Based upon these principles many variations in the actual construction both in form and in detail in the apparatus may be made within the principles set forth.
