| 191 | Pocket tool | US743034 | 1996-11-04 | US5857268A | 1999-01-12 | Kyunghan Park |
| An exact movement of the scissors is provided by using elastic power of an elastic panel fixed on the fixed scissors body, wherein the front edge is installed in the coupling groove of the moving scissors body. A lighter or the flashlight may be mounted on the pocket tool. By installing the rear part of the elasticity panel such that the front edge has a part cut properly on the same line and to cooperate with the fixed scissors body and by installing the front edge of the part in the coupling groove made in the lower edge of the moving scissors body, it is possible to move the scissors exactly and repetitively because only the front edge part of the elasticity panel conveys the elastic power and is confined by the moving scissors body. The rear part of the elasticity panel is fixed on the fixed scissors body, and the flashlight or lighter etc. is coupled to the hollow surface formed by the coupling projection of the body. | ||||||

| 196 | Hand tools | US885365 | 1992-05-19 | US5235750A | 1993-08-17 | Frank R. Brown |
| Shear-type cutters for hard and/or large thickness workpieces having a pair of shearing-action cutting jaws, laterally abutting each of which jaws is a hold-down clamp member having a hold-down surface positioned opposite the other of said jaws. Each hold-down surface is moveable with respect to its associated jaw away from the jaw it opposed through a wide range of distances, normally is in alignment with the cutting surface of the jaw to which it as affixed, and is resiliently biased against being so moved. Thereby, when the jaws close on a workpiece of any of a wide range of thicknesses, the hold-down surfaces of the clamps come into contact with and yieldingly remain pressed against the outer surfaces of the work piece to hold it in place as the cutting jaws impinge upon and cut through it. | ||||||
| 197 | Thermoplastic-fabric sear-cutting handtool | US539883 | 1990-06-18 | US5046251A | 1991-09-10 | Pamela C. Scott |
| A low-cost hand-portable light-weight tool ideally suited for seamstress or upholster in domestic or commercial work, employing an electrical/heating-element of substantially known type of construction, into at least one blade member; whereby three species of the invention are set forth including variants thereof: a.) a scissor like embodiment, whereby the essential cutting and searing function is achieved under normal scissoring action by virtue of the oppositely closing blade's vertical shearing action relative to the opposed planar surface of the substantially thermoplastic fabric material, a species performing particularly effectively upon such fabrics having a proponderance of natural fibers in the weave, as well as ultra-sheer synthetic fabrics; b.) a fixed V-mouthed configuration similar to an opened scissor, therefore essentially relying upon a transversely moving manual thrust penetration into the fabric edge, generally more suitable for those heavier fabrics having a higher-percentage of thermoplastic-fibers in the weave; c.) a mono-bladed basic embodiment of the invention, whereby a handle portion includes a heating-tip having a fairly sharp blade edge which is directly applied anywhere upon the planar surface of the fabric, including a flat backing panel serving as a provisional working surface during the manual drawing procedure;--all three species serving to simultaneously cut and minutely sear those severed fibers so as to negate occurance of fraying threads, and hence resulting in an exceptionally clean `finished edge`, ultimately saving the labor and expense involved in otherwise providing conventionally sewn seam construction. | ||||||
| 198 | Cutting apparatus | US445545 | 1989-12-04 | US5044243A | 1991-09-03 | Tokushi Aizawa |
| A cutting apparatus including a pair of blades respectively having linearly extending cutting edges so that the cutting edges are brought into sliding contact with each other to cut a member to be cut which is put between the cutting edges. The cutting apparatus is provided with press members for bringing the sliding contact surface of one of the cutting edges into press contact with the sliding contact surface of the other when the two blades are brought into sliding contact with each other, the press members being disposed along one of the blades. Thus, the sliding contact between the two blades is ensured independently of the rigidity of the blades. Accordingly, it becomes possible to reduce the thickness and increase the length of the blades. | ||||||
