  • Patent number: 11498814
    Abstract: The present invention relates generally to a claw device for installing, removing, and repairing a manhole assembly. Claw device may include a base assembly and two or more arm assemblies. The arm assemblies may be configured to pivot in response to movement of a slide along an axis of a shaft extending upwardly from base assembly. In particular, when a lifting force is applied to the slide, one or more grip pads of arm assemblies may be configured to move inwardly toward the shaft and frictionally grip a surface of the manhole assembly. In one aspect, at least one arm assembly includes an extending member having a plurality of positions for adjusting the length of at least one arm assembly. Advantageously, claw device may be adjusted to accommodate for manhole assemblies of different diameters or other objects having various shapes and sizes.

  • Patent number: 9918591
    Abstract: An apparatus includes a spatula surface having a plurality of holes. The spatula surface is configured for handling food during a cooking process and for enabling fluids to drain through the holes. An arm supports the spatula surface during the cooking process. A handle is joined to an end of the arm. A drainer is positioned generally horizontally above a top surface of the spatula surface for contacting food positioned between the spatula surface and the drainer, and for enabling a pressure to be applied to the food to substantially remove excess fluids from the food. Attaching bars support the drainer and enable movement of the drainer relative to the spatula surface. A lever is joined to the attaching bars for enabling a user to impart a relative downward movement of the drainer to apply the pressure to the food, thereby enabling the user to substantially drain the excess fluids.

  • Patent number: 8579342
    Abstract: This invention provides a post hole digger having a first, traverse pivot point, located on the lower section of two handle members, and a second, blade assembly pivot point located at the medial point of the blade assemblies. Because the first pivot point is a traverse pivot point, the handle members are only required to travel through a limited range of motion. Additionally, the second, blade assembly pivot point is preferably an offset pivot point. Thus, because the second, blade assembly pivot point is disposed at a medial point the blade assemblies, the motion of the handle members, which are coupled to the upper ends of the blade assemblies, is reversed relative to the lower ends of the blade members.

  • Publication number: 20110254302
    Abstract: A system for displacing a floating object comprising a jaw assembly and at least one latch assembly. The jaw assembly supports the latch assembly such that, when the latch assembly is in a latched configuration, the latch assembly maintains the jaw assembly in an open configuration and, when the jaw assembly is in the open configuration, the at least one jaw assembly defines a jaw gap through which the floating object may pass. The latch assembly is adapted to engage the floating object when the floating object has passed through the jaw gap such that the latch assembly is placed from the latched position into the unlatched position to allow the jaw assembly to move from the open configuration into the closed configuration. The jaw assembly is adapted to engage the floating object when in the closed configuration.

  • Patent number: 7896415
    Abstract: An easy package lifting tool designed to allow a user to manually lift a package with one hand directly over the package's center of gravity that uses the weight of the package to exert inward directed forces by two gripping jaws on opposing sides of the package. The tool includes two pads pivotally attached to the distal ends of two main arms. The two main arms cross and are pivotally attached together vertically above the center axis of a line that extends between the two pads. Attached to the proximal end of the first main arm is a secondary arm. Pivotally attached to the proximal end of the second main arm is a lift arm. The distal end of the lift arm is pivotally attached to the secondary arm. Formed on the proximal end of the lift arm is a curved handle section. The location of the second pivot point between the secondary arm and the lift arm is offset from the first pivot point and the center axis of the two grippingpads.

  • Patent number: 5795004
    Abstract: A device for scooping or grasping an object on the floor and then lift it to hand level. This device is primarily for use by a person who cannot bend to pick up an object from the floor. An extendable/retractable lazy tong assembly is connected at one end to an extension on a cane-like member and at the other to a scoop assembly. The scoop includes two hinged halves that move apart, are placed around an object, are moved together to scoop up the object. By pressing the cane extension against the floor, the lazy tongs are caused to rotate and extend, lifting and moving the scoop to within reach of the user's hands without requiring the user to bend over. The scoop can also include pinch bars for pinching, then lifting, a flexible sheet, such as paper or cloth. A thin bar may be provided on the scoop for insertion into items such as key rings or necklaces to lift them to the user's hand level.
