Patent number: 9119498Abstract: A culinary tool is provided including a handle and a housing that pivot relative to one another during a forward stroke of the handle to incrementally move, and optionally ratchet, a ram within the housing toward a cutting grid, thereby extruding food through the cutting grid. A cutting blade, joined with the handle distal from the pivot, travels along a blade path near the cutting grid to mince the extruded food. The blade can be joined with the handle at a cantilevered connection, and can be flexible so that as it moves along the blade path, a portion of the blade flexes to allow the blade to cut the extruded food material without binding as the blade moves across the cutting grid. The blade can include one or more sledded feet that project outwardly from the blade and that guide the blade near the cutting grid in a non-binding manner.Type: GrantFiled: March 8, 2012Date of Patent: September 1, 2015Assignee: Grace Manufacturing, Inc.Inventors: Jonathan B. Schmidt, Dennis P. Haggerty

Patent number: 8640587Abstract: A hand-operated cutting apparatus including a main frame at least including a front wall, a base wall and two side walls, in which an opening is formed in the front wall, and a rack formed on an upper surface of the base wall along the length of the main frame, a bracket disposed between the side walls of the main frame and movable along the length of the main frame, a cutter provided in the front of the main frame and including a cutting blade located within the opening, and a squeezer attached to the front surface of the bracket facing to the cutter. The bracket includes a base, a handle pivotally provided on the base and a pusher arm pivotally provided on the handle, in which a lower end of the pusher arm is located between two teeth of the rack, and the pivot axis of the pusher arm on the handle departs from the pivot axis of the handle on the base towards the rear of the main frame.Type: GrantFiled: June 30, 2009Date of Patent: February 4, 2014Assignee: Cosso International Ltd.Inventors: Yiu Joe Cheung, Chung Wai Stephen Chan

Publication number: 20090272281Abstract: A slicing and dicing device which includes a pivoted lever which when stroked slides a pusher assembly partway along on a main body towards a cutter piece to slice an interposed item. Gearing operated by the lever disengages after each stroke to allow another stroke, reducing the peak effect required by limiting the range of motion to a range where good leverage is obtained. A dicing assembly is mounted forward of the cutter piece for vertical sliding motion to allow cross cutting of strips sliced out of the item by the cutter piece.Type: ApplicationFiled: October 27, 2008Publication date: November 5, 2009Inventors: Lance Hood, Joshua R. Stewart

Patent number: 7493841Abstract: A machine for slicing food products, including a supported table surface with aperture for the passage therethrough of product slices; a power-driven cutting device having a horizontal blade extending above the table surface at a distance substantially corresponding to the slice thickness required; a guided horizontally sliding platform spaced above the cutting device; a power-driven reciprocating lateral thruster attached to the horizontal sliding platform for the purpose of moving the platform both to produce slices of food product and to clear the cutting device in the case it is jammed; and a vertical tube-shaped open-ended hopper rigidly supported by the horizontally sliding platform for containing a stack of food product items, the lowest item in the stack resting on the table surface and being pushed by the hopper into contact with the cutting device to produce a slice.Type: GrantFiled: January 19, 2005Date of Patent: February 24, 2009Inventor: Robert E. Kaplan

Patent number: 7313993Abstract: A feed device (1) for a microtome, in particular for a cryostat microtome, for setting the cut thickness of the specimen (2) to be sectioned, is described. In order to set the cut thickness, either the cutting knife or the specimen holder (3) is mounted on a slide (8) in a slide guide (4) and is connected non-positively to a drive motor (5). The drive motor (5) is connected either to an eccentric cam (6) or to a helical cam (7), and the nonpositive connection between the motor (5) and the slide is accomplished via the eccentric cam (6) or the helical cam (7).Type: GrantFiled: March 5, 2003Date of Patent: January 1, 2008Assignee: Leica Microsystems Nussloch GmbHInventor: Klaus Foerderer
