Nov. 10, 1953 H. R. CASELLA RECEPTACLE ANlj SUPPORT THEREFOR Filed 00 3, 1950 INVENTOR HWWCM Patented Nov. 10, 1953 UNITED STATES @TENT OFFICE Claims priority, application Argentina November 15, 1949 2 Claims. (01. 220-1) The present invention relates to a mixing device for obtaining by centrifuging comestible liquid or semi-liquid mixtures and combinations, said device being based on a receptacle for containing the substances to be mixed or combined and is characterized by a separable coupling device for coupling said receptacle to a supporting column provided with means for fixing the same to any supporting base. An essential object of this invention is to provide a device of the class referred to which comprises a mechanical com bination of elements arranged in mutually cooperative relationship to provide a manually operable driving assembly for a vertical shaft carrying the stirring means for the substances contained in the receptacle. Said driving assembly comprises a train of gears which includes a toothed wheel fast on a manually operable shaft, said wheel meshing with a pinion fast on a shaft manually operable independently of the shaft of said toothed wheel. Said pinion is integral with a step-up gear wheel meshing with the pinion of a vertical shaft to which are separately and interchangeably connected the shafts carrying the stirring members for the substances to be subjected to the action of said members, said gear train forming a means whereby an axial rotary motion is transmitted to the shafts carrying the stirring members, at two speeds, one of which is accelerated by the action of the shaft carrying the toothed wheel meshing with the pinion associated with the second shaft. said pinion together with the gear wheel integral therewith its the highspeed rotary motion transmitting unit to the pinion integral with the shaft transmitting the axial rotary motion to the stirring members. lhe second slower rotary motion is provided by the second shaft the gear wheel of which causes rotation of the pinion fast on the shaft carrying the interchangeable stirring members.

The apparatus assembly is complemented by other constructional and functional features to be hereinafter described in accordance with the accompanying drawings in which a practical embodiment is illustrated by way of example, wherein:

Figure l is an elevation of the apparatus assembly with parts thereof in section,

Figure 2 is a plan View illustrating the assembly in cross-section along the line A--A of Figure 1, and

Figures 3, 4 and 5 illustrate the respective shafts carrying the stirring members consisting of a liquifying mixing and beating unit.

in the figures the same reference numbers and.

letters are used to indicate similar or corresponding parts.

In the embodiment shown in the drawings the device according to the present invention comprises a receptacle 04 consisting of a hollow body of irregular lateral shape having curved portions as at 2 extending radially inwardly and forming internal ribs 2. These ribs as may be appreciated assist in obtaining a complete agitation of the contents of receptacle a which, near the mouth thereof has embedded therein a ring 3 adapted to allow a hook portion d of a hooked arm to be inserted thereunder. Hooked arm 5 is integral with a supporting column b and serves to support receptacle a. At a certain distance from hooked arm 5 there is provided on column b a projection t (Figure l) which constitutes a lateral steadying member for receptacle a and acts to maintain the same in a proper vertical posi tion and parallel to column b. Near the lower end of column b and integral therewith there is provided a clamping device consisting of forked member arranged opposite a plate ii. Passing through plate 8 there is provided a screw 9 operable by means of a wing nut it or any equivalent element and that end of screw 9 between fork member l and plate d has fast thereon a conical washer Ii. The clamping device as may be seen is provided for fixing the mixer in a suitable position on a table or the like.

At one end of column b there is provided a widened head portion forming a casing 52 within which a driving pinion i3 is mounted for rotation. Pinion it is fastened to the upper end of a driving shaft it guided in a boss it which. depends from the lower surface of the aforementioned casing. Shaft it extends transversally of said casing and has secured thereto a sleeve is constituting a coupling shaft Hi and the stirring elements which will be described hereinafter.

Pinion l3 meshes with a step-up gear is secured on a vertical shaft as to which is also fastened a toothed pinion 2d. Shaft it extends r through the outer wall of a recess formed in a cover plate 22 of casing l2 and constitutes a handle receiving portion 23 for handle 2d. Toothed pinion 2E meshes with a step-up gear i5 secured to a shaft 26 mounted for rotation on coverplate 22 and extending through recess 2| to provide a handle receiving portion 2'! similar to that previously described. Handle 24 may be removably mounted on either portion 23 or portion 2! of shafts l9 and 26 respectively as desired or required.

Sleeve I6 is provided with a bore 29 into which driving shaft [4 is keyed and to the lower end of this shaft there is secured one end of a helical expansion spring 30 whilst the other end of said spring bears against the upper end of a vertical shaft 3| which projects into said bore and is provided with a pin 32 for coupling the shaft to the lower portion of sleeve l6 which for this purpose is provided with corresponding slots into which the ends of pin 32 are inserted when shaft 3| is in the correct angular position. To the lower end of shaft 3| there is secured a' stirring; plate 33 of hexagonal shape.

The apparatus also comprises two further shafts 34 and 35 to the lower ends ofwhich are secured, respectively, blades 36 having a cutting edge 3! for slicing, when necessary, solidly'placed in receptacle a and a set of rings 38 normally fixed so as to form a whipping unit. Blades 36 constitute a liquifying unit and the respective ends thereof extend obliquely one with respectto the other, the arrangement being such that it is possible to achieve a high degree-of efliciency in the liquifying process.

Although in the foregoing description reference has been made to liquifying, mixing and whipping units each fixed to an individual shaft it will be understood that the arrangement may be such that these units can be rem'ovably and interchangeably attached to one single shaft. In this case, upon conclusion of the mixingior' combining process, the interchange of the whipping and mixing units on the shaft may be effected without the necessity of removing shaft 3| from coupling sleeve |9 it being evident that only r ceptacle arequires removal.

The mixer operates as follows: once the receptacle a has been placed inposition on column b and charged with the substances to be treated rotation of the blades at accelerated speed may be produced by placing handle 24 on handle-receiving portion 2! of shaft 26 and rotation thereof will cause the step-up gear 25 to rotate and the latter will transmit its movement to pinion and hence to step-up gear l8 which is in"- tegral with pinion 2D. The accelerated movement of gear l8 is transmitted to pinion l3 fast on shaft M to which shaft 34' or3l is coupled as the case may be.

For whipping which requires rotation at a lower speed it is sufiicient to place handle 24' on handle-receiving portion 23 of shaft |9 whereby the multiplication of speed through theaction of gear is eliminated.

It will be understood that while a preferred embodiment of the invention has been described,

many modifications and variations may be introduced in the structural details without departing from the scope of the invention as defined in the annexed claims.

I claim:
