jz ss BY Q411 United States Patent 3,172,442 COMMINUTING DEVXCE Fritz @tto, Hameln (Weser Germany, assignor, by mesne assignments, to Bolder Trust reg, Vaduz, Liechtenstein Filed June 4, 1962, Scr. No. 199335 Claims priority, application Germany, June 8, 1561, St 13,557 13 Claims. (Cl. 146-68) My present invention relates to a comminuting device, also known as a blender, for foodstuffs and other fibrous materials adapted to be introduced as a viscous mass or slurry into a receptacle.
In such blenders it is customary to provide one or more cutting blades spinning at high velocity about a generally vertical axis above the bottom of the receptacle, the rotation of the blades imparting to the entrained mass a circular motion which centrifugally urges its particles against the suitably curved peripheral wall of the receptacle and upwards therealong to create a toroidal vortex whereby the particles are circulated time and again past the sweep of the blades for repetitive comminution and thorough intermingling. For this purpose it is necessary to position the blade or blades at a certain level above the bottom of the receptacle, the optimum level varying with the volume of the mass and, therefore, with the extent to which a given receptable has been filled. Thus, eliicient operation under different loading conditions would call for different cutting units interchangeably attachable to the blender shaft, yet this solution is usually impractical since the correct installation of such units requires not only time but also a certain skill in assembling and disassembling which may.
unduly tax the abilities of the average user, e.-g. a housewife. Attempts at making the elevation of the blades adjustable have not let to commercially realizable constructions.
It is, therefore, the general object of my present invention to provide an improved device of the character referred to in which these disadvantages are avoided and which by simple manipulation may be adapted for efiicient use with full-capacity and partial-capacity loads.
This object is realized, in accordance with my present invention, by the provision of a removable insert between the receptacle bottom and the cutter assembly rotatable thereabove, this insert forming a false bottom whose spacing from the cutting blade or blades is substantially less than that of the original bottom whereby even small quantities of material tobe processed in the blender can be effectively comminuted. Advantageously, the insert is held against rotation relative to the receptacle by a simple retaining member in the receptacle bottom proper, preferably a non-circular plug received in a mating cutout of the receptacle bottom and traversed by the cutter shaft upon which it bears with resilient pressure to act as a packing therefor.
The invention will be described in greater detail with reference to the accompanying drawing in which:
FIG. 1 is at top plan view of a blender according to the invention;
FIG. 2 is an axial sectional view taken substantially on the line IIII of FIG. 1;
FIG. 3 is a fragmentary cross-sectional view taken on the line III-III of FIG. 2;
FIG. 4 is a bottom view of the device with parts broken away; and
FIG. 5 is a cross-sectional view taken on the line VV of FIG. 2.
The blender shown in the drawing comprises a cupshaped receptacle l with a curved peripheral wall portion 2 merging into a substantially fiat bottom 3. This bottom is formed with a cutout 16 of roughly rectangu- "ice lar configuration in which there is seated a stepped plug 6 of similar shape. The plug 6 has a central bore 4 traversed by an upright shaft 5 that is driven by a suitable motor (not shown) to which it may be removably attached in any convenient manner. The upper, larger step 'of plug 6 fits into a mating cutout 17 of a generally disk-shaped insert 7 removably resting on the receptacle bottom 3.
The recepticle 1 is formed with legs 18 by which it can be supported on the motor housing. A cover 19 may be hinged to it at 20' and may be fastenable in closed position by any suitable means such as, for example, a pin passed through a bore 20 in a lug 21. It will further be seen that the insert 7 has a virtually fiat inner zone 7a (FIG. 2) whose outer radius substantially equals the length of the blades 9', 9", in contradistinction to the receptacle bottom 3 whose flat upper surface merges with the curved peripheral wall 2 in the vicinity of that radius; this accounts for a further reduction of the clearance below the blades.
It will be noted that, in the particular embodiment illustrated, the false bottom formed by insert 7 approximately halves the distance between the upper blade 9' and the receptacle bottom 3 while reducing the elevation of the lower blade 9" above its base to a fraction of its original value. Thus, even small quanties of foodstuff or other materials may be effectively subjected to the action of the blades.
Modifications of the specific arrangement described and illustrated are, of course, possible without departing from the spirit and scope of my invention as defined in the appended claims.
