| 101 | Shielded cable cutting device | US288442 | 1988-12-22 | US4901438A | 1990-02-20 | Brian E. Gibney |
| A battery powered hand-held rotary cutting tool for use on BX cable and the like comprising a power unit and attached battery pack with a projecting drive shaft to which is affixed a rotary cutting blade. Said power unit and battery pack fit within a containment shell which is fitted with a top cover which closes onto the containment shell and simultaneously depresses an activation switch in said power unit. A projecting portion of said cover further operates to press a segment of shielded cable into contact with the rotary cutting blade contemporaneously with the activation of said power unit. Said top cover is fashioned with a spring on the inner cover such that when the cover is released by the mechanic or operator, the power activation switch is released thereby. The invention is designed to facilitate one-handed cutting of shielded cable by means of squeezing the device onto segments of cable wherever the mechanic desires to cut the shield. | ||||||
| 102 | Rotary scalpel blade and blade protector structure | US23651 | 1987-03-09 | US4899742A | 1990-02-13 | George H. Muller |
| Rotary scalpel blade and blade protector structure. The rotary scalpel blade in one embodiment is circular and has a sharpened outer periphery and an opening through the center thereof for securing the blade to means for rotating the blade. In modifications of the circular scalpel blade the sides of the scalpel blade may be concave, depressed or flat with an annular groove around the outer periphery thereof. The rotary scalpel blade may also be a linear radial scalpel blade sharpened on one or both edges. The blade protector structure in one embodiment includes a disc having a disc shaped pocket in the center thereof split centrally to receive a scalpel blade, held together with a living hinge and locked in closed position by a split cylinder positioned over a cylindrical flange on one side of the blade protector. In another embodiment, the blade protector is a plastic envelope including a recess open on one side and having slots extending thereacross with a reduced opening at the top for receiving blades to be protected. A further embodiment of the blade protector is a flat, flexible sheet having a tacky adhesive on one side thereof. | ||||||
| 103 | Rotary scalpel method | US422847 | 1982-09-24 | US4791928A | 1988-12-20 | Joseph J. Berke; George H. Muller |
| A manual method of making a surgical incision in free tissue including moving a freely rotatable circular scalpel blade across an area of the free tissue at a desired incision depth without pressing the tissue to a mechanical backing member wherein the circular scalpel blade is rotated solely by friction between the blade and the tissue in which the incision is required. The scalpel blade may be pushed or pulled across the area of free tissue, preferably at a speed of between four and seven centimeters per second. | ||||||
| 104 | Blade for a vibratory cutter | US603935 | 1984-04-26 | US4615119A | 1986-10-07 | David S. Johnson; Everett L. Haas |
| A blade for a vibratory cutter having a plurality of serrated teeth. A plurality of first teeth provided on one side of the center line of the blade are angled in one direction, and a plurality of second teeth provided on the second side of the center line are equally angled to the first set of teeth in the opposite direction. When used in conjunction with a vibratory tool, the blade will sever material in two directions parallel to the surface endeavored to be cut. | ||||||
| 105 | Rotary cutting wheel and method of making | US223080 | 1981-01-07 | US4349963A | 1982-09-21 | Francis C. Peterson |
| A rotary cutting or shearing wheel of one-piece configuration formed from sheet stock including an extruded hub section and a dome wheel section including a cold formed, feathered, cutting edge at the outer periphery. | ||||||
| 106 | Roving cutter | US735539 | 1976-10-26 | US4081904A | 1978-04-04 | Duane D. Krohn; Samuel W. Culbertson |
| A lightweight, compact roving cutter for chopping fiberglass roving into short fiber segments, and used in conjunction with a hand-held resin spray gun, has a cutter roller carrying a plurality of blades, a back-up roller cooperating with the cutter roller and the blades thereof for breaking or cutting the roving, and an idler roller cooperating with the back-up roller for feeding roving between the cutter and the back-up roller. The back-up roller is mounted for movement toward and away from both the cutter and the idler rollers in substantially equal increments relative to each, and a positive displacement adjusting means is connected with the back-up roller for controlling the clearance between the back-up roller and both the cutter and the idler rollers, the adjusting means including a manually operable portion remote from said cutter, whereby an operator may conveniently and accurately adjust the clearances between the rollers while the cutter is operating. | ||||||
| 107 | Power cutter | US3670412D | 1970-09-28 | US3670412A | 1972-06-20 | CUNNINGHAM FRANK W |
| A power cutter for cutting deformable material and including a frame which has upper and lower jaws for receiving the material to be cut. The lower jaw includes a recess within which a cutting disc is rotatable by an associated power drive. The upper jaw is formed with depending cheek portions located on opposite sides of the cutter means to define side passages. The cheek portions extend forwardly of the cutter disc in overlying relation to a projecting guide shoe portion of the lower jaw to thereby define a frontal passage ahead of the cutting disc. The access openings to the frontal passage and the side passages are made sufficiently large that the material to be cut can pass therethrough, but sufficiently small that a person cannot inadvertently insert his finger and become cut by the cutting disc. The recess within which the cutter is rotatable and which is defined by the frame upper and lower jaws is of inverted Ushape to make accidental insertion of a finger even more difficult, the material to be cut deforming into a corresponding U-shape for entry and cutting thereof.
