| 121 | Blade cover for cutting device | US10083760 | 2002-02-26 | US20030159293A1 | 2003-08-28 | Elaine DiPalma |
| The present invention is directed to a cutting device comprised of a first blade portion having a handle and a cutting surface and a second blade portion having a handle and a cutting surface. The first and second blade portions are coupled together and intersect at a pivot point. A rivet is mounted through the pivot point attaching the first and second blade portions, where then rivet further comprises a head elevated with respect to the first blade portion. A cover for covering at least a portion of the first and second blade portions is provided. The cover has a rivet head receiving slot so that when the first and second blade portions are in a closed position and when the cover is positioned over the first and second blade portions, the rivet head frictionally engages the receiving slot so that the cover is frictionally attached to the rivet head. | ||||||

| A cutting device especially designed for cutting up salad greens includes two blades, a rib and handles. The two blades are inter-secured to rotate together about a common axis, but are spaced apart from each other along the common axis. The rib is pivotably secured to the two blades so as to rotate about the common axis, and is curved in a direction of rotation so as to have a concave surface. The handles are integrated with the two blades and the rib to control the two blades and the rib to rotate simultaneously between open and closed positions. The concave surface of the rib is the lead surface when moving from the open position to the closed position, and the cutting edges of the two blades cross edges of the concave surface when moving from the open position to the closed position, so as to perform a cutting action. | ||||||

| Iluminating scissors including a pair of blades pivotally joined in an intermediate portion thereof by a bolt engaged with a hexagonal lock nut and each having a handle at an end thereof, a cylindrical housing mounted on one of the blades, a light bulb arranged in a cylindrical edge of the cylindrical housing, a battery fitted in the cylindrical housing and electrically connected with the light bulb, and a switch mounted on the cylindrical housing and electrically connected with the battery and the light bulb, and a linking rod having a first end connected with the housing and a second end with one of the blades, whereby the illuminating scissors will direct light onto the cutting surface. | ||||||
| 125 | Cutting tool | US231048 | 1994-04-22 | US5419048A | 1995-05-30 | Terence P. Horgan; Jan L. Roth |
| A three bladed cutting tool (10) with a middle blade (16) provided between the other two blades (12,14). The middle blade (16) is pivotal relative to the other two blades (12,14). A thin ribbon of swarf (102) is removed from the sheet material (100) in a cutting operation. The cutting tool (10) discharges this swarf (102) from the cutting zone in a direction substantially transverse to the cutting direction. An angled cutting edge (68, 68') on the middle blade (16) directs the swarf (102) out through an opening (72) provided in at least one of the other two blades (12,14). | ||||||
| 126 | Rotary blade cutter | US379996 | 1989-07-14 | US4972585A | 1990-11-27 | Yutaka Sasaki |
| A rotary blade cutter (10) including a semitubular rotary cutting blade (12) rotatably mounted within a tubular housing (14). The tubular housing 14 includes an entrance slit (22) and a diametrically opposed exit slit (24) for insertion of a web into the cutting device. A first cutting edge (32) is formed along a first side of the entrance slit. The semitubular rotary cutting blade includes a first slit (36) nominally aligned with the housing entrance slit when the rotary blade is in a retracted position, and includes a second cutting edge (48) that is formed adjacent a second side (46) of the entrance slit to oppose the first cutting edge. The second cutting edge is tapered to spiral around the longitudinal axis of the housing. The rotary cutting blade includes a spiral groove (50) that coacts with a guide pin (52) projecting inwardly from the housing to constrain the rotary cutting blade to rotate about the longitudinal axis of the housing when the rotary blade is longitudinally advanced within the housing. As the cutting blade rotates, the second cutting edge moves progressively past the first cutting edge to cut the web inserted therebetween. | ||||||
| 127 | Torque limiting device for shears | US215078 | 1988-07-05 | US4964216A | 1990-10-23 | Robert G. Gosselin |
| A shearing device capable of being articulated between open and closed positions for cutting material includes pairs of handle levers and shearing elements rotatably mounted on a pivot mechanism. A clutch assembly comprising plates with complimentary and fixed configurations biased in abutting and intermeshing relationship when in a predetermined rotary alignment is positioned between the pairs of handle levers and switching elements. The clutch assembly is responsible to a predetermined force generated when the handle levers are articulated towards a closed position and the shearing elements encounter cut resistant material for camming the plates out of meshing relationship and operatively disconnecting the handle levers. | ||||||
| 128 | Cutting instrument with breakaway finger loop | US2276 | 1987-01-12 | US4759127A | 1988-07-26 | Clair H. Gingher, Jr. |
| A cutting instrument, such as a thread nipper, is provided with a safety breakaway finger loop. In use should the cutting instrument inadvertently be engaged and pulled into a textile machine, for example, the finger loop engaging the hand of the user will automatically breakaway from the body of the cutting instrument. | ||||||
| 129 | Hand operated metal shear | US14933 | 1987-02-13 | US4753011A | 1988-06-28 | Joseph F. Long |
| An improved hand operated metal shear that removes a strip of metal in small sections with the lower cutter attached to the upper handle by a cylindrical post of lesser diameter than the strip of metal removed so that the shears may be turned sharply to either side without distortion of the metal being cut and with the upper box-like cutter having a curved bottom to facilitate cutting of corrugated metal. | ||||||
| 130 | Scissors with cushioned stop | US328651 | 1981-12-08 | US4407069A | 1983-10-04 | John A. Conners |
| First and second metal blades made from uniform thickness stock are fashioned into scissors which may be disposable suture scissors. Each of the blades is stamped from sheet metal, they are pivoted together, and handles extend in the opposite direction from cutting edges on the blades. Resilient means is provided by the handles being resilient and stop means are provided to limit the closed position of the cutting edges to prevent overriding, namely overclosing, of the cutting edges. The stop means includes first and second stop surfaces integral with the first and second blades, respectively. The stop surfaces are close to the pivot relative to the length of the handles, the blades have only frictional opposition to movement until the stop surfaces engage, and then the subsequent stressing of the resilient means establishes a cushioned stop of movement of the handles without any further movement of the cutting edges past the fully closed condition. The foregoing abstract is merely a resume of one general application, is not a complete discussion of all principles of operation or applications, and is not to be construed as a limitation on the scope of the claimed subject matter. | ||||||

| A thread snip comprising a pair of handle members formed of a resiliently deformable material and defining interlocking flange portions cooperating to support the handle members for swinging movements between open and closed positions and mounting a pair of bent metal cutting blades for operative cutting engagement incident to movement of the handle members towards closed position. | ||||||

| In each of the illustrated hand tools, each blade is secured to a tang in the form of a strip of carbon steel, the whole tank being sheathed in plastics material to form the shank and handle. In one embodiment each blade is formed by a strip of carbon steel integral with the tang, and on which a blade edge has been formed, the width of the strip in the blade being, in general, less than that of a conventional blade but having a backing of plastics material molded along the strip to make up its width.

| A cutter suitable for cutting, for example, swaged-on metal collars of lockbolts to facilitate removal of the lockbolts has two blades movable to bring their cutting edges together to cut a collar beteen them, and has resilient guides attached to the blades for guiding the blades to cut a collar or other workpiece symmetrically.
