Abstract
This invention involves a novel blade holder for use in food-processing machines particularly skinning machines. This blade holder has as two major elements a top and a bottom piece having at their front terminal portions a place where the blade is clamped. In the center section of each piece are a number of connecting screws or bolts which not only connect the top and bottom pieces but also act as a fulcrum. Thus, when the rear sections of the top and bottom pieces are forced apart by a lever action, their front terminal portions move tightly together to form a firm grip or clamp effect on the blade. To remove the blade, the rear sections are brought closer together thus releasing the tight clamp in the front terminal portions and thus releasing the blade.
Claims11
A blade holder comprising in combination a top piece, a bottom piece, at least one connecting means to connect the top and bottom pieces and a cylindrical cam means, said top piece being movable and having an inner surface which abuts an inner surface of said bottom piece, the inner surfaces of said top piece and said bottom piece forming thereby a clamping means to hold a blade therebetween, at least one cavity or openings provided in said inner surface of said top piece having an open portion abutting said inner surface of said bottom piece, said connecting means fixed to and extending upwardly from said inner surface of said bottom piece, said connecting means fitting through and locked within said openings of said top piece when in a locked position, and when said connecting means are disengaged from said openings said top piece is removable from its connecting mode with said bottom piece, said top and bottom pieces having said clamping means at their front portion to hold a blade therebetween, the inner surfaces of said top and bottom pieces in contact with tightening cam means at their rear sections to move said top and bottom pieces together at their front portions to thereby tightly hold said blade therebetween, said connecting means providing a fulcrum upon which said top piece and said bottom piece will move to form a clamping means in their front section, said cam means comprising a substantially cylindrical rod with a flat portion or face on its circumference which extends throughout the length of said rod, said rod fitted in between the rear sections of the inner surfaces of said top and bottom pieces, said rod being rotatable therein to force said top and bottom pieces apart and to bring them toward each other.
A blade holder comprising in combination a top piece, a bottom piece, connecting means to connect said top piece to said bottom piece, and a cylindrical cam means, said top piece having an inner surface abutting an inner surface of said bottom piece, said top piece having in its inner surface at least one cavity or openings with open portions abutting said inner surface of said bottom piece, said openings located substantially midway along a width of said top piece, said top piece having at its rear section at its inner surface a cutaway portion defining a cam housing, a substantially cylindrical rod positioned in said cam housing and adapted to contact both said inner surface of said bottom piece and an inner portion of said cam housing, said connecting means fixed to and extending upwardly from said inner surface of said bottom piece, said connecting means having a stem and wider head portion, said connecting means located in said bottom piece at positions substantially adjacent said openings in said top piece, said connecting means providing a fulcrum upon which said top piece and said bottom piece will move to form a clamping means in their front section, said tightening cam means comprising said substantially cylindrical rod with a flat portion on its circumferential portion which extends throughout the length of said rod, said rod fitted in between the rear sections of the inner surfaces of said top and bottom pieces, said rod being rotatable therein to force said top and bottom pieces apart and to bring them toward each other.
