  • Patent number: 4184397
    Abstract: A device for slicing tomatoes and other soft food objects has a hollow triangular enclosure frame with three vertical sides disposed about an open interior into which tomatoes are inserted. The longest vertical side or hypotenuse side of the vertical frame enclosure carries a tensioned rack of parallel blades with sharp cutting edges facing inwardly. The opposite intermediate length side of the frame has a pusher sliding back and forth along it with spaced fingers inserted between the opposite cutting blades. Insertion of tomatoes is facilitated by a vertically movable loading platform mounted within the frame which can be manually raised by a push rod at the top to receive a tomato and then lowered below the path of movement of the pusher to permit the pusher to traverse the tomato along and through the cutting edges of the blades to slice it. The loading platform has a table rotatably mounted at the top of a lifting lever which is rotatably mounted at the bottom of the frame.

  • Patent number: 4144784
    Abstract: A guard for preventing the operator's fingers from contacting the sharp edges of a parallel rack of blades in a food slicer, such as a tomato slicer is provided by a set of parallel planar segments intermeshed between and extending slightly in front of the sharp edges of the blades when the pusher is deployed away from the blades in position for introducing the object (tomato) to be sliced between the pusher and blades. A latch, such as a gravity latch, holds the assembly in the open guarded position until the tomato is introduced and the latch is released. In a rotary slicer a small portion of the blades adjacent the pusher are unguarded to facilitate introduction and prescoring of the tomato.

  • Patent number: 4137807
    Abstract: A convenient and inexpensive apparatus for slicing, dicing and cutting foodstuffs, such as fruits and vegetables, especially those having varying densities throughout their volume, comprising a horizontal base member having a plurality of upstanding peg members to support an article to be cut and a pivotable cutting frame supported by the base member and carrying a plurality of slicing knives each of which has a double-edged knife surface for cutting through the article. A detachable dicing frame can be slidably inserted adjacent the knife frame assembly for the dicing of an article.

  • Patent number: 4082024
    Abstract: Improvements in apparatus and methods for cutting potatoes into strips, wherein the potatoes are carried hydraulically in single file against and through an arrangement of knife blades, rapidly and with great force. The improvements reside in the manner in which the potatoes are preconditioned for cutting, the mechanism by which the potatoes are aligned in the hydraulic stream as they approach the knives, and the knife device by which the potatoes are effectively cut into strips.

  • Patent number: 4038892
    Abstract: A food slicer with an indexing turret is disclosed in which the turret has four faces, two of which have upstanding blades of different sizes on opposed faces, and two of the faces have a different offset relationship to the center line of the turret. An angled blade is provided in a table blade segment opposed to the angled turret. A table lock segment slidingly fits into the body of the slicer, and its angled front edge portion locks the indexing turret into position for the varying slices to be made. A pusher which is held by the hand is held on top of the foodstuffs to be cut, and optionally has a guide underportion which, when approaching the last slice, engages the body side guide rails in order to minimize the amount of uncut foodstuff. The table blade segment may be positioned by means of a table blade latch into two parallel ways, one above the other, thereby providing for two different thicknesses of slices due to the position of the blade which is angled at one end of the table blade segment.

  • Patent number: 3961551
    Abstract: Disclosed is a hand-operated device for slitting fabric drawn therethrough into strips. The device has a V-shaped bracket which is secured over the edge of a table top by a wedge, without using any tools. Fabric is drawn by hand from the edge toward the interior of the table top between a row of blades extending upwardly from the device and a guard bar disposed over the blades. The device can be disassembled, without using any tools, to reposition the blades so as to cut strips of different widths or to replace blades. Except for the blades, the device is entirely formed of an inexpensive plastic material formed by a process such as molding.

  • Patent number: 3948132
    Abstract: An apparatus for slicing fruit and vegetables such as potatoes, carrots and onions as well as tomatoes and hard boiled eggs and the like. A set of parallel cutting blades are positioned in a horizontal plane within a frame member for initially receiving the article to be cut while an article engaging member or pusher is pivotally connected to said frame for engaging and forcing said article through said cutting blades.

  • Patent number: 3942399
    Abstract: Apparatus for slicing onions and other hard vegetables. The apparatus comprises carrier means mounted for movement through a cutting path in a first direction. A plurality of cutting blades is disposed within the path in a downwardly descending ramp. Each of the blades includes a leading edge and a trailing edge, with the leading edge forming the cutting edge of the blade. The blades are sequentially offset from one another in said one direction and parallel to one another in the direction normal to said one direction, with the leading edge of one blade spaced from the trailing edge of the preceding blade by a distance at least equal to the thickness of the blade.The carrier means serves to carry the vegetable through the path and into sequential contact with succeeding blades to effect the sequential slicing of the vegetable.The carrier means comprises a base for supporting the vegetable and a pusher member.
