Patent number: 7963429Abstract: The mid-zone pressing tool has a base and a pressing assembly, which are pivotally connected at the rear by a transverse shaft. A pair of cantilevers extends forward from each side of an uppermost rear portion of the base. A pair of arms is connected on the distal ends by a common handle. A first coupling connects a middle portion of each arm to the pressing assembly by an axle, cam or link. A second coupling connects the proximal ends of each arm to the cantilever by an axle, cam or link. Pushing the handle down pivots the arms, engages the couplings, and transmits a concentrated downward force to the front of the pressing assembly. The cantilevers allow a range of coupling placements, including near the middle of the pressing tool. The couplings are optionally releasable.Type: GrantFiled: August 21, 2007Date of Patent: June 21, 2011Inventor: William Carlton Zolentroff

Patent number: 7950557Abstract: An air duster duct is formed to branch off at an intermediate portion along the length of an air duct which connects a compressed air supply source with a pneumatic tool. A valve mechanism having a selector valve and an operating device is provided at the branch portion. The sector valve can shift to a first position where the selector valve opens an upstream side duct which communicates with the air supply source to a downstream side duct which communicates with a nailing machine and shuts the upstream side duct relative to the air duster branch duct and a second position where the selector valve shuts the upstream side duct relative to the down stream side duct and opens the upstream side duct to the branch duct. The selector valve is operated from the outside by the operating device.Type: GrantFiled: December 7, 2007Date of Patent: May 31, 2011Assignee: Max Co., Ltd.Inventors: Takeo Fujiyama, Tatsushi Ogawa, Susumu Hayashi

Patent number: 7950555Abstract: A stapler is stacked on top of a roll-type tape dispenser. The tape dispenser top surface and the stapler base bottom surface have complemental three dimensional contours which cause the tape dispenser and stapler longitudinal axes to be in parallel relationship when the surfaces are in abutment, prevent relative displacement of the tape dispenser and the stapler when they are stacked and permit the stapler to be dismounted from the tape dispenser and rested for separate use on a flat surface in a stable condition.Type: GrantFiled: December 20, 2005Date of Patent: May 31, 2011Inventor: Steven P Dewald

Publication number: 20110114692Abstract: A driving device for resetting a hitting nail bar of the pneumatic nail gun, which is mounted in a gun body including a main air chamber, a trigger valve, a hitting nail bar and a bottom cylinder chamber disposed therein is provided. The driving device includes a main gas channel and a sensing valve component slidably disposed in the main gas channel. The main gas channel communicates with the main air chamber and the bottom cylinder chamber via the trigger valve. The sensing valve component is controlled by the position of the hitting nail bar to be either opened or closed. The sensing valve component is opened on the condition that a reset state of the hitting nail bar is excluded, and the high-pressure air is introduced from the main air chamber into the bottom cylinder chamber to drive the hitting nail bar to move upwardly to reset rapidly.Type: ApplicationFiled: December 16, 2009Publication date: May 19, 2011Inventors: CHIA-SHENG LIANG, Chu Hsiang Tseng

Patent number: 7942299Abstract: A tool that includes a housing, a motor assembly, a hook structure and a detent. The motor assembly has an output member and is at least partially housed in the housing. The detent has a first portion, which is engaged to the housing, and a second portion that is engaged to the hook structure. The first and second portions cooperate in an engaged condition to hold the hook structure in a selected rotational position relative to the housing. The first and second portions being disengagable to permit rotational movement of the hook structure relative to the housing. The hook structure can include a friction enhancing portion that is employed to provide better gripping performance.Type: GrantFiled: May 31, 2006Date of Patent: May 17, 2011Assignee: Black & Decker Inc.Inventors: Glen V. Steinbrunner, Andrzej R. Wojcicki, James R. Niblett
