  • Patent number: 9221156
    Abstract: A motorized hand tool such as a cordless ratchet wrench is configured for reducing assembly and disassembly processes. The motorized hand tool includes a motor end plate that may be fastened to a drive member such as a ratchet head assembly without the use of fasteners or assembly tooling such as presses, fixtures or hammers. A flange on the motor end plate can pass through a keyway in a periphery of the ratchet head assembly and may be then be rotated out of the keyway and into a peripheral slot of the ratchet head assembly. A rib protruding inwardly from a clamshell housing portion of the tool closes the keyway to prevent the flange on the motor end plate from rotating back into the keyway.

  • Patent number: 9149917
    Abstract: A hand tool, such as a motorized cordless ratchet wrench, is configured for reducing part count and reducing assembly processes. The hand tool includes a clamshell housing that may be fastened to a drive member such as a ratchet head assembly without the use of additional fasteners such as large clamp nuts or additional screw sets, for example. One or more protrusions extending inwardly from the clamshell housing engage similarly shaped voids in the ratchet head assembly. The protrusions tightly engage the ratchet head housing when the clamshell housing portions are fastened together.

  • Patent number: 9114512
    Abstract: A motorized hand tool, such as a cordless ratchet wrench, is configured for reducing part count and reducing assembly processes. The motorized hand tool includes an overmolded window for a light emitting diode (LED) in a clamshell housing. An LED is secured within the clamshell housing by conductors extending from the LED that are encapsulated in rigid sleeves. The rigid sleeves provide a friction fit in a channel between fingers molded in the clamshell housing. A switch assembly of the motorized hand tool is mounted in the clamshell housing and covers channel to contains the conductors and sleeves. By containment of the rigid sleeves and conductors, the LED is located securely in the overmolded window.

  • Patent number: 8665058
    Abstract: A variable speed toggle switch that allows a user to reverse a rotational direction of a motor and supply variable amounts of power to a motor, such as in a power tool, for example, a power drill. A trigger can include a gear segment that meshingly engages a gear on a potentiometer to electrically communicate the actuation direction and actuation amount of the trigger to a microprocessor. The microprocessor can then signal to an H-bridge, or to a series of transistors, the actuation direction and actuation amount of the trigger. A motor or other device can be powered by a power source in an amount corresponding to the actuation amount, and in a direction corresponding to the actuation direction of the trigger.

  • Patent number: 7980321
    Abstract: The present disclosure relates to an anvil, an anvil and socket combination and an anvil attached to a power tool. The anvil structure includes a drive head with an end and a body portion having a channel spaced there between. A friction ring is retained in the channel. Flats are provided on the end and on the sides of the end and the square portion in a coordinating alignment such that the flats generally lie in the same plane. The ring retained in the channel between the end and the portion at least partially extends relative to the flap. A transition cone is provided on the anvil for distributing impact load. Additional, relief grooves are provided on corners of the polygon portion to help further relieve stress in the anvil structure.

  • Patent number: 6394566
    Abstract: A storage riser for mounting atop a work surface has an open-front wall structure including rear, side and top walls and a bifold door assembly for closing the front opening. The door assembly has an upper panel hingedly connected to the front of the top wall and a lower panel hingedly connected to the bottom of the upper panel for pivotal movement between a vertical, unfolded, closed position and a non-vertical, folded, open position disposed in the storage compartment adjacent to the top wall. Coupling brackets respectively project inwardly of the compartment from the opposite sides of the lower panel adjacent to its upper end, the brackets respectively carrying guide rollers which respectively roll in channel tracks on the side walls. Opening of the door assembly is assisted by gas springs, respectively disposed adjacent to the side walls and having cylinders pivotally coupled to the coupling brackets and rods pivotally coupled to the side walls adjacent to the lower end of the front opening.

  • Patent number: RE36379
    Abstract: A tool chest includes a lidded base defining a storage compartment therein and a pegboard-type tool pallet adapted to carry tools on an obverse side thereof and shiftable between a first position overlying and covering the storage compartment with the obverse side up, and a second position upstanding from the rear end of the base with the obverse side forward and supported against the open lid for uncovering and providing access to the storage compartment. In one embodiment the pallet is pivotally connected to the base with a link arm and has handles for lifting the pallet between its first and second position. In a second embodiment the pallet is pivotally connected to the lid so that when the lid is opened it pulls the pallet up to its second position. The front end of the pallet has pins or rollers supported on guide rails for guiding movement between the first and second positions.
