In any event, successive knives cut different slices from the onion O. The shafts 34 may be made of progressively different lengths so that knives 35 are disposed at progressively different heights to enter the recesses 16 between successively different pairs of discs 14, and thereby cut progressively different slices S in the onions placed in the pockets 18, as the table 12 rotates or the knives can be disposed at progressively different heights on their respective shafts 34. The shafts 34 are mounted parallel to shaft 15 and spaced equi-angularly thereabout so that the knives 35 are interleaved with the different discs 14 to enter the recesses 16 thereof and to pass through the pockets 18 as the discs 14 revolve with shaft 15. In each pair of arms there is journaled a shaft 34, to the bottom of which there is fastened a rotary knife 35. Welded or otherwise secured to base 10 to project thereabove are a plurality of angularly spaced uprights 30 to each of which is welded, or otherwise secured, a pair of parallel, horizontally-projecting arms 31, 32. Nuts 24 and a flexible washer 25 hold the discs 14 on the shaft 15. The table is driven by a gear-motor unit of conventional form, indicated generally at 20, through gearing 21, 22, 23, the last-named being coupled to shaft 15. The apertures in one disc register with the apertures in all the other discs to form therewith a plurality of pockets 18 equi-angularly spaced about the axis of shaft 15 and table 12. Each disc is recessed on its lower face as denoted at 16 and each disc is provided with a plurality of equi-angularly spaced apertures 17 therethrough. Shaft 15 is journaled at its lower end in base 10. Mounted on the base is a table 12 comprising a plurality of coaxial discs 14 which are keyed to a shaft 15 to rotate therewith.
Referring now to the drawing by numerals of reference, 10 denotes the base plate of the machine which is supported on a plurality of legs 11, only one of which is shown. 3 is a diagrammatic view illustrating how an onion is sliced by the machine of this invention. 1, looking in the direction of the arrows andįIG. 2 is a sectional view taken on the line 2-2 of FIG. 1 is a plan view of an onion slicing machine built according to one embodiment of this invention įIG. Other objects of the invention will be apparent hereinafter from the specification and claims, particularly when read in conjunction with the accompanying drawing.įIG. The primary object of this invention is to provide a machine which will be simple in construction and which can cut an onion into the required number of slices in one operation and in one set-up, and without waste.Īnother object of the invention is to provide a machine of this nature which is relatively compact, and which employs readily replaceable and inexpensive cutting tools.
Moreover the known machines can cut only thick slices. The several portions, that are gouged-out in toto in cutting the several slices in the onions amount to a rather considerable portion of the total thickness of the onion, sometimes as much as a quarter and this is all waste. The cutting blades have to be of substantial thickness, and therefore must gouge out of the onions portions of substantial thickness as they pass through the onions.
The machines heretofore provided for these purposes, and particularly those for slicing onions, are wasteful of the product. The present invention relates to machines for slicing vegetables, fruits, and the like, and more particularly to machines for slicing onions that are to be canned, frozen, fried, or otherwise preserved or processed.
