ABSTRACT:
The cutter comprises a cutter body having an upper support surface formed with an elongated rectangular opening with inwardly extending rails on the opposite longer sides of the opening and on one end of the opening. An open rectangular support frame is engageable with the rails and has a length less than that of the opening, for reciprocation along the rails, and coil springs, engaged in recesses in one end of the rectangular opening bias the support frame to engage the other end of the opening. An open rectangular blade frame is removably and conformingly seated in the opening of the support frame, and has a plurality of cutting blades extending longitudinally across the opening therein in equispaced substantially parallel relation. A pressing cover is hinged at one end to the cutter body and has a free end provided with an operating handle, and the pressing cover has projections on its inner surface engageable through the spaces between the cutting blades. The end of the support frame opposite that engaged by the coil springs is formed with downwardly and outwardly tapered grooves, and the cover, adjacent its free end, is provided with wedges engageable in the groove. When a vegetable or fruit to be cut is placed on the blades and the cover is pressed down, the article to be cut is cut due to the pressure exerted by the pressing cover and, at the same time, the engagement of the wedges with the tapered grooves forces the support frame to move longitudinally of the opening in the support surface against the bias of the coil springs, so that the blades exert a moving cutting action on the article to be cut at the same time as the projections on the inner surface of the cover force the article between the blades. A second open rectangular blade frame is provided with cutting blades extending transversely across its opening in equispaced substantially parallel relation. For cutting a vegetable or the like into square pieces, the two blade frames may be superposed on each other and mounted in the support frame. In this case, the cover does not have the wedges, so that cutting into squares is effected by downward pressure exerted by the pressing cover without any movement of the support frame and the blade frames. The projections on the inner surface of the cover are preferably square so as to be engageable in the square recesses defined by the two sets of blades.
