Definitions

  • a removable vegetable peeling attachment for use at variable high speeds on a household liquidizer power unit including a bowl that journals near its bottom a rotatable concave disk having holes therethrough with sharp edges, and, in coaction therewith providing a helically inclined ramp along-a part of a circular wall bordering the edge of the disk to gently turn or tumble vegetables contacting the disk and slow their movement below a locked on cover that prevents vegetables leaving the bowl during peeling.
  • the invention contemplates a high speed disk scraping a thin surface layer from a vegetable with an interface contact speed high enough and the frictional contact low enough that the vegetable is subjected to a minimum degree of propulsion and tends to move slowly around the center of a bowl-like container as it is positively retarded and tumbled with resulting rotational inertias that continually and progressively bring different areas gravitationally in contact with the scraping disk.
  • the disk is upwardly concave to assist some radial movement of the vegetable and to follow more closely the roundness of the vegetable while forcefully centrifugating peeling waste against the wall of the container from below the disk and into a collecting space that is below any area of rolling contact that occurs between the vegetable and the wall of the container.
  • the scraper is a circular disk of uniform thickness and has holes within its periphery preferably punched by dies whose draw is towards the upper face whereby sharp square abrading edges are left on its concave face.
  • the size of the holes are related to permit a limited curved area of a vegetable to be exposed'downwardly in the holes enough under its weight to be scuffed or scraped by the abrasion of the trailing edges of the holes moving swiftly in contact with the vegetable, it being found that repeated scraping of the skin surface of a vegetable will break away the skin whereas a knife will cut deeper than the skin in order to remove the skin.
  • a safety factor for users whose touch perception will not be destroyed by knives before reaction occurs, if the disk is inadvertently touched.
  • Vegetable sizes vary. The greater the size and weight of vegetables, the heavier the contact at the holes, the flatter the curvature of the vegetable entering each hole, and the less the depth of abrasion due to the relative curvatures with respect to the hole size.
  • the speed at which the vegetable is scraped be varied for various surface conditions of the vegetables but size can also be accommodated by varying the liquidizer motor speed, and a tumbling bar LII or rail is provided at the edge of the disk over a part of the inner circumference of the container as spaced therefrom and helically inclined to accommodate and tumble various sizes of vegetables.
  • the circularly inclined bar both lifts and retards the side of the vegetable that contacts the bar in directions different to the bodily movement induced by the scraper disk. The result is a vegetable action that continually presents a heterogeneously changing area contacting the scraper disk without undue waste of substrate material before the vegetable is adequately peeled.
  • the rail can be a molded element on the side of the bowl wall, either as a separate shelf member secured thereto or as an integral ledge formed by offsetting the wall of the bowl. In all instances, however, the waste can be readily washed away.
  • FIG. 1 is a perspective view of an embodiment of the invention in which a vegetable peeler attachment is mounted on a liquidizer power unit;
  • FIG. 2 is a perspective view of the embodiment shown in FIG. 1 with the elements detached to show the manner of attachment and the container wall broken away to show the interior construction of the attachment;
  • FIG. 3 is a plan view of portion of a container showing the embodiment of FIG. 2;
  • FIG. 3A is a plan view of portion of a container showing another embodiment of the invention.
  • FIGS. 4 and 4A are vertical sections taken on lines 4-4 and 4A4A of FIGS. 3 and 3A, respectively.
  • FIG. 5 is a perspective view of a clamping member I shown in FIG. 2 to resiliently secure the container on the power unit.
  • the power unit or base 10 of a universal motordriven, variable speed liquidizer is shown in FIG. 1 which is more particularly described in ADAJIAN, No. 3,575,524. It comprises a molded plastic housing 12 with a universal motor mounted therein (not shown) and carries an integral top collar 14 to receive the reduced bottom 18 of a peeler attachment 20 and nonrotatively engage peripheral recesses 22 in the wall of the reduced bottom 18 by peripherally spaced lugs 16 of elastomer material.
  • the upper end of the motor shaft (not shown) carries a lower drive coupler 24 having resilient axial teeth 26 that releasably interdigitate with the spokes 28 of the driven coupler 30 on the lower end of a driven shaft 32 journalled in the bottom wall 34 of the attachment 20 when located in operative position.
  • the base 10 has a switch panel 36 with push buttons 38 for selective graduated speed control and a timer dial control 39 as described, for example, in Swanke et al., US. Pat. No. 3,678,288.
  • the bottom wall 34 is recessed upwardly at 40 to accommodate the driven member, and the driven member is threaded thereon at 42 in the direction of rotation to rotate the shaft 32 as journalled in a sintered bearing sleeve 44 secured in the axial boss 46.
  • washer 48 engaging the upper end of the sleeve 44 supports an upwardly concave scraper disk 50 that is secured to the shaft in driven relation by a screw 52.
  • the disk 50 is provided with holes 54 having a dimension of /4 inch to 3/8 inch in the direction of rotation and the holes preferably are unevenly spaced from the center of rotation.
  • the holes are die formed with the punch die moving through the disk towards its concavity and thereby providing a sharp corner edge 56 at the concave surface 58 around the holes.
  • a substantially circular wall 60 of the container 20 surrounds the scraper disk 50 a spaced distance from its periphery 62 and proximate to the periphery of the disk a tumbling bar 64 is provided extending approximately 90 around the disk, starting at the level of the disk edge 62 and inclined upwardly in the direction of disk rotation, arrow 66, along a substantially helical path to a position well above the disk a distance related to the radius of a large vegetable to be peeled, illustrated in broken lines 68, having a diameter less than approximating the radius of the container 60.
  • the tumbling bar 64 is a curved metal rod 70 (FIG. 4) approximately inch in diameter turned downwardly at the ends to form legs 72 and offset radially at 74 inwardly therefrom a distance not to exceed the vertically projected periphery of the disk.
  • the rod 70 is also secured intermediate its ends by at least one L-shaped rod member 76 attached thereto with its lower portion forming a leg 70A parallel to the end legs 70.
  • the legs are received in vertical cored bosses 78 molded on the inner wall of the container 60 into which the legs are pressed for rigid support.
  • FIGS. 3A and 4A another embodiment is illustrated wherein the bar 64 is formed in the molding of the container.
  • the wall of the container where the rod 70 would be located is inwardly offset at 80 to provide a helical ledge 82 defining a tumbling bar 64.
  • the offset occupies approximately only one fourth of the inner circumference of the container wall.
  • An optimum speed for operating the scraper disk 50 is approximately 8,000 RPM. and in operation a potato can be rapidly peeled in to seconds with a gentle rolling action which does not bruise it.
  • the cover 86 and the bayonet members 90 on the edge of the cover loosely engage the mating edge 92 and lugs 84 on the container and in view of the versatility and safety of the disk from a user viewpoint, the relative heights of the cover and container walls can be designed for best manufacturing economies and user convenience.
  • the cover looseness permits any contact between vegetable and cover to urge the securement of the bayonet fastening, the bayonet joint being preferably one with rotational limits in the direction of disk rotation but without a cam tightening.
  • FIG. 5 To support the assembled container and cover against possible gyration if a large potato is in motion therein, reference is made to FIG. 5 where a clamp member 94 for that purpose is shown formed from sheet metal.
  • the central portion 96 is disposed at the bottom of the container 34 of the container 20 and has a central opening 98 which clears the driven member 28 and concentric arcuate slots 100 therearound by which the clamp is mounted by rivets 102 for limited rotation.
  • the rotation is controlled by a handle 104 whose alternate clamping position is shown in broken lines 104A.
  • the central portion 96 is provided with cams 106 which in the clamp release position clear the internal resilient lugs 16.
  • cams 106 which in the clamp release position clear the internal resilient lugs 16.
  • the cover 86 can be easily removed, the container lifted from the top of the power unit and the peeled vegetables lifted out. The container can then be immediately or shortly thereafter easily rinsed clean under a water faucet and returned to storage with the liquidizer power unit 10 available for other purposes.
  • the cover is easy to use and is mandatory for safety sake, even though there is little likelihood of injury to the user from the scraper disk if inadvertently left off.
  • peeler container and cover are made Having thus described the invention and the structure and operation of the preferred embodiments, it will be understood how the objects and results are accomplished and how various modifications can be made therein without departing from the spirit of the invention within the scope of the inventive concept.
