  • Patent number: 7416143
    Abstract: The invention is a tablet crusher including a linkage that is operable to bring to bear a force on a platen so as to urge it against an anvil, wherein platen and anvil are shaped so as to bring about a crushing force upon a tablet disposed therebetween. The device comprises: (1) a base; (2) an anvil integrally fixed to the base, the anvil having a concave crushing face; (3) a platen having a convex crushing face, coupled at a pivot to the base so as to be moveable against the anvil; (4) a screw actuator for facilitating movement of the platen against the anvil, the screw actuator having a handle; whereby movement of the handle produces movement of the platen relative to the anvil, for crushing a tablet between the anvil and the platen.

  • Patent number: 7413137
    Abstract: A manually operable pill crusher device for use with pill pouches. A base includes a crushing surface over which a head is mounted. A handle is attached to a cam inside the head, and the head has a slot that permits the handle to move from a horizontal position to a vertical position. The cam is mounted inside a ram which slideably moves axially inside the head from a raised position in the head when the handle is vertical to a lowered position when the handle is horizontal. The ram includes a crushing surface engaging surface. The head also includes a slot through which a pill in a pouch can be inserted on to the crushing surface when the handle is raised. Lowering the handle then crushes the pill with axial force directly over the crushing surface, avoiding any cocking or arcuate pressure on the pill.

  • Patent number: 7302887
    Abstract: A kitchen hand tool for crushing, slicing, or juicing food products. The tool is operated by closing two handles that rotate a drive gear that engages the ratcheting tooth portion of a crush paddle resulting in the movement of the crush paddle toward a basket, crushing and discharge of the food item through the basket. A drive pawl forces the drive gear to rotate counterclockwise, which in turn forces ratcheting tooth portion and subsequently the crushing paddle down in a clockwise direction applying crushing force on the garlic or any item placed in the crushing area. As the drive gear turns until it clicks past a locking pawl. This cycle of opening and closing the handles is repeated until the crush paddle is fully advanced and can move no further and is against the basket.

  • Patent number: 7249724
    Abstract: An apparatus for destroying compact discs includes a base and a cover. The base has a mounting fixture capable of holding a CD and an anvil projecting upwardly from the base bottom panel. The cover is hingedly attached to one of the base walls such that the cover can assume an open position in which the apparatus interior is accessible and a closed position in which the apparatus interior is inaccessible. The cover has one or more scatter shields projecting downwardly from the cover such that, in the cover's closed position, the scatter shields prevent the apparatus interior contents from escaping. The cover further includes a compressor projecting downwardly from the cover top panel. In operation, mounting a CD in the mounting fixture and urging the cover from the open position to the closed position induces the compressor to urge the CD against the anvil to shatter the CD.

  • Patent number: 7240870
    Abstract: A hand-held device for shredding paper comprising a pair of rotary cutting wheels disposed within a housing between an inlet slot and an outlet slot. A motor is positioned in the handle to drive the cutting wheels through a gear assembly. One wheel serves as a drive wheel, which is coupled directly to the gear assembly, and the other wheel serves as an idler, driven from a spur gear attached to the drive wheel at the end opposite a gear case. Paper sheets are fed into the inlet slot and pulled between the wheels. Wheels are comprised of a stack of alternating discs of a large and small radius, and staggered so as to allow the two wheels to be interleaved while rotating in opposite (clockwise and counterclockwise) directions and maintain clearance. Large discs have a frictional edge to grab and feed the paper into the intersection of the wheels, tearing the paper into strips and forcing the strips into the outlet slot. A battery compartment in the handle contains the batteries for energizing the motor.

  • Patent number: 6637685
    Abstract: A pill crusher has an arm extending over and along an elongate base, with a pivotal connection between the base and one end of the arm. An upwardly open cylindrical housing on the base has a longitudinal axis perpendicular to the base and a compression spring in the cylindrical housing between a cylindrical anvil member and the base. Interengaged guide formations on the housing and the anvil member at opposite sides of the housing are inclined so as to cause rotational movement of the anvil member relative to the cylindrical housing on displacement of the anvil member along the longitudinal axis against the action of the spring; and a cylindrical pressure member depending from the arm above the cylindrical housing. In use, the rotational movement of the anvil member causes a pill to be both crushed and also simultaneously ground between the pressure and anvil members, which have serrated opposed faces to improve the grinding.
