In food processing apparatus having a working bowl with a motor-driven shaft extending vertically upwards through the bottom of the bowl and various selected rotary tools having disc-like cutting tool members positioned in the top of the bowl which can be engaged with this shaft for processing food introduced through a feed tube in a cover secured over the bowl during use, improved rotary food processing apparatus is provided preventing the cutting surfaces of the disc-like member from inadvertently coming into contact with the undersurface of the cover. The disc member is provided with one or more rounded bearing elements elevated above the cutting elements by a small amount, for example in the range from 1/32 to 3/32 of an inch. These bearing elements are positioned closely adjacent to the periphery of the disc member, and in one illustrated embodiment the bearing element is formed directly at the periphery, thereby not impeding the feeding of food items to the cutting elements in the disc member. In normal operation the cutting elements clear the cover by a slightly greater amount than the elevation of the bearing elements for example ⅛th of an inch, such that these elevated bearing elements also clear the undersurface of the cover. In the event that the user inadvertently overloads the rotating disc cutting tool in either manner described, these bearing elements advantageously slide against the undersurface of the cover almost effortlessly for holding the cutting elements spaced slightly away from the horizontal undersurface of the cover thereby protecting both the cover and the rotating tool.

In rotary food processing apparatus having an upright working bowl with a vertical motor-driven shaft extending up into the bowl with its axis of rotation extending along the central axis of the bowl and in which a cover is secured in position extending across the top of the bowl in use, such cover including an upright feed tube which is offset entirely to one side of said axis of rotation, said feed tube serving for introducing food items down therethrough into the top of the bowl and in which a rotary tool has an elongated hub removably engaging down upon said drive shaft in driving relationship therewith and has a horizontal disc-like cutting member secured to the top of said hub which rotates about said axis of rotation in use, said disc-like cutting member having a horizontal area with a downturned flange around the perimeter thereof and with cutting means thereon projecting above the upper surface of said horizontal area, the improvement comprising means for preventing said cutting means from engaging the undersurface of the cover on the opposite side of the axis of rotation from said feed tube, said means including a bearing element positioned on said horizontal disc-like cutting member near said downturned flange, said bearing element being located near said cutting means within an angular displacement of no more than 45° therefrom, said bearing element having a bearing surface elevated above said cutting means, said elevated bearing surface being smooth and being adapted to slide on the undersurface of the cover on the opposite side of the axis of rotation from said feed tube for holding said cutting means down away from the cover in the event that the user overloads the rotating disc-like member by pushing food items too vigorously down through said offset feed tube causing the sector of the rotating disc-like member beneath said feed tube to deflect downwardly while the opposite sector of the disc-like member on the opposite side of the axis tends to be correspondingly deflected upwardly.
