Detailed Description oE the PreEerred Embodiment Referring initially to FIG. 1 of the drawings, food processor 11 appliances oE the type to which the invention is applicable may take a variety oE forms and in this par-ticular example ~8 of the form having an upriyht body 12 supporting a cylindrical food receptacle 13. The receptacle 13 and a removable cover 14 of the receptacle are preEerably formed oE transparent material to facilitate observation of the progress of food processing operations. An electrical motor 16 within body 12 drives the Eood processor 11.
Suitable detailed constructions for the above described components of the food processor 11 are known to the art.
The present food processor 11 differs from the prior con-structions in that the Eood working component wlthin recept,-acle 13 is a peeling attachment 17. The peeling attachment 17 of this embodiment is removable f~rom the food processor ll to enable other;operations to be performed with other attachments although the peeling~attachment ~ay be a perman,-ent component~in IDstances~where~the processor is to be used exclusively for pe~eling~operations.
~: : : :
~ eferring now to FIG.~2, the drive output shaft 18 from motor 16 is~ aligned in a vertical direction and is centered wl~th~respect to the food receptacle 13. The dri.ve shaft 18, which~haa~a~hexa~gonal~cross sectional configuration in this type of food pro,ces~sor~ 11, extends upward into r~cep~acle 13 through~a~cylindrical sleeve 19 at the base of the receptac-, ~le~.~ Shaft~ extends~above;the upper end of sleeve 19 to a~subs;tantially~higher~level~within receptacle 13.
Referring~jointly to FIGS. 2 and 3, the peeling attach-ment~17~hàs~a;tubular hub ~21 proportioned to be fitted onto the upper~por~t1~on oE~drive~shaft 18. An annular lip 22 at : , , : :

-`` lZ~7S~2 the upper end oE hub 21 seats against the top of drive shaft 18 to hold the hub at an intermediate elevation within the space enclosed by t~e receptacle 13 and cover 14. ~t that location, the lower end of the hub 21 extends a short dis-tance into the upper end of sleeve 19. This prevents entry of peelings into the sleeve.
ReEerring now to FIGS. 2 and 4 in conjunction, the axial passage 23 within hub 21 has a hexayonal cross section conforming to that of the food processor drive shaft 18.
Thus the hub 18 is rotated by shaft 18 when motor 16 is aict-uated.
Referring again to FIGS. 2 and 3, the peeling attachment 17 has a disk 24 portion which is coaxial with the hub 21 and which may be integrally formed with the hub. Disk 24 has a diameter conforming to the inside diameter of recept-acle 13 and connects with hub 21 near the lower end of the hub at a level immediately above the top of sleeve 19.
Disk~29 has an~abrasive upper surface 26 which abrades or grinds away the dry brittle outer covering of garlic cloves or the like that rest on the disk when the apparatus is in operation. While the disk 24 can be formed of metal havlng m1nute shar;p projections on the upper surface, the present embodiment has an advantageous laminated construc-tioniwith the~lower lamination 27 being hard plastic inte-gral with the plastlc material of hub 21. The upper lamin-ation~28 i9 ~abraslve~sheet materlal such as sandpaper which is secured~to~ the lower lamination 27 with adhesive. The sandpaper~is p~réferably of a grade having moderately coarse : :

to be peeled are deposited on top of disk 24. The cover 14 is then replaced and n~otor 16 i8 actuated. Rotation of the abrasive surface 26 then abrades away the outer coveriny oP
those portions oE the garlic cloves or the like that are in contact with the surface. Rotation of the disk 24 also agi-tates and turns the cloves or the like causing all outer portions of the cloves to contact the disk and be peeled within a short period of time. The food processor 11 is then shut down to minimize abrasion of the inner portions of the cloves which are to be used as a food ingredient. The ~--The transparency of the receptacle 13 facilitates monitoring of the peeling operations to enable prompt deactuation of the motor 16 when the process has been completed. Cover 14 may then be removed to recover the garlic cloves or the like and the peelings may be removed by lifting the attachment 17 from drive shaEt 18. The pee~ling operation proceeds very quickly and without the difficulties and problems encountered in manual peeling of such food items.
While the invention has been described with respect to a single preferred embodiment, many modifications in the construction are poseibl~e and it is not intended tp limit the invention except as defined in the following claims.
