Rising from, simple and rugged device for extracting juices , base H) are four standards or legs l5-l8 in and breaking down the structure of oranges, lem clusive, upon which is supported a box-like struc ture generally designated as 28. Box 29 may have front wall 2| and rear wall 22, the rear wall ons and other fruits as well as vegetables, such as _ carrots, spinach, etc. In the case of fruits,‘par ticularly citrus fruits, it is well known that the juices thereof are highly corrosive to ordinary metals and materials. Due to the delicate flavor of many fruits, contamination with certain metals imparts an objectionable metallic taste to the fruit. Furthermore, the highly corrosive action of citrus juices on metals such as alumi ‘ num and steel results in discoloration and thus makes it dif?cult to maintain a clean and whole some appearance of the article. In addition to the above, it is essential that a device for extracting juices and crushing fruit and vegetables and used in homes be relatively inexpensive, simple, and be easy to disassemble and clean. The invention herein provides a structure which ful?lls the above requirements’ to a remarkable degree. In addition, the struc ture is susceptible, to the incorporation therein of such-construction materials as wood or plastic whose characteristics for kitchen use are highly desirable. The use of wood in kitchenware is particularly advantageous in that tooling costs 10 preferably being higher than the front wall. , A pair of side walls 23 and 24 extend between the front and rear walls, and these side Walls are preferably inclined toward each other as shown so that a minimum separation is at the bottom thereof and a maximum separation is at the top. The'bottom of box 2|] may be covered bv plate 25 having slot 26 extending lengthwise between walls 2| and 22. Side walls 23 and 24 have aligned journals 30 and 3| formed therethrough. It is preferred to have journal 30 larger than journal 31 for a purpose to be explained hereinafter. Passing through aligned journals 3E! and 3! is shaft L5 having round bearing portion 36 co operating with journal 30 and round bearing por tion 31 cooperating with journal 3!. Between bearing portions 36 and 31, shaft 35 is shaped to a non-circular section and, in its simplest form as shown here, may be shaped as squared’shaft section 38. Loosely mounted 'upon' square shaft portion 38 but rotatably locked thereto are a pair of discs 40 and 4|. Both of these discs are similar in construction and have relatively mas sive hub portions 43 tapering to thin peripheral portions 44. Hub 43 is, apertured at 45 so that the discs may clear square shaft 38 while tilting back and forth, In order to rotatably lock the discs on square shaft portion 38, locking member 46 maybe set in at the center of each disc. Lock for the manufacture thereof are comparatively small and resulting articles possess a desirable appearance and may be maintained clean in simple and effective ways. The invention in general contemplates the use of a pair of discs tilted with respect to each other. The tilting is such that a region of wide disc separation provides a feeding region while a region of minimum disc separation provides an 40 ing member 46 consists of a thin disc having operating or crushing region. square aperture 41 therethrough corresponding In order that the invention may be more fully understood, reference will now be made to the to square shaft 38.
