Patent number: 8307557Abstract: A foot operated cutter has an elongated handle with a pair of cutting jaws mounted on one end thereof and a gripping member at the other end thereof. The cutting jaws are mounted on separate spaced apart pivot axles. The upper end of each jaw is pivotally coupled to a movement arm and the two movement arms are pivotally coupled to each other. One movement arm is coupled to a foot operable lever. Movement of the lever causes the movement arms to pivot and move the upper ends of the jaws apart from each other resulting in the lower ends of the jaws coming together in a cutting action. A biasing member preferably urges the jaws to an open position. An adjustable stop is preferably provided and prevents the lever from putting too much force on the jaws.Type: GrantFiled: December 7, 2009Date of Patent: November 13, 2012Inventor: Timothy J. Rodgers

Patent number: 7263775Abstract: An illuminating nail clipper for clipping the nails of an animal such as a dog, cat, bird, or the like which allows for the clipping of an individual nail at the desired length to prevent injury or improper length cutting for the animal. The device includes a hand-actuated clipping blade used in conjunction with an adjustable in size nail holder which includes a cutting hole and which allows the nail to be clipped to be firmly held at a particular position relative to the nail cutting blade. A light source illuminates an animal's nail to make it translucent, allowing the operator to see the capillaries within the nail and thus to avoid cutting to the live portion of the nail.Type: GrantFiled: July 15, 2004Date of Patent: September 4, 2007Inventor: Reynolds E.

Publication number: 20040060415Abstract: A cutting device has a body, a driving device, a moving base, a head and a cutting rod. The driving device is mounted on the body to actuate the moving base to move relative to the body. The head extends from the body and has a central hole defined through the head. A notch and an exhaust hole are defined in the bottom of the head and communicate with the central hole. The cutting rod is moveably received in the central hole in the head and is attached to the moving base. The cutting rod has a cutting recess defined around the cutting rod. Accordingly, the metal waste generated during the cutting process is kept from flying about and injuring the user, so the safety of using the cutting device is improved. In addition, the cut metal sheet can be kept from shake or vibration.Type: ApplicationFiled: September 27, 2002Publication date: April 1, 2004Applicant: Pro-Bin International LimitedInventor: Cheng-Yen Wu

Patent number: 5727318Abstract: The clipper of the present invention includes a clipper handle with a first component and a second component which are moveable with respect to each other. A nail holder extends from the clipper handle, the nail holder having a curved cross section. A slot for receiving the fingernail to be clipped is defined in the nail holder. A blade is slidably mounted with respect to the nail holder, and has a cross section which corresponds to the curved cross section of the nail holder. The blade terminates in a blade edge. The nail holder and the blade are each mounted to one of the first and second components. Therefore, when relative movement is effected between the handle components, a sliding action takes place between the nail holder and the blade to cut a nail which has been inserted into the slot in the nail holder. The curved cross section of the nail holder and the blade ensures that the nail will be cut in an ideally rounded configuration.Type: GrantFiled: December 23, 1996Date of Patent: March 17, 1998Inventor: Gary J. Reiswig

Patent number: 5628105Abstract: An impact tool for seating and cutting plural wires in a telephone wire termination block includes a movable cutter containing guide and shear elements having a spacial periodicity which differs slightly from that of terminals of the termination block. A force release mechanism in the tool handle includes a plunger translatable along the axis of the handle that engages a shaft for a stationary cutting head. The plunger passes through a bore of hammer which has a transverse bore sized to receive plural balls that are urged against and retain the plunger with the hammer. A main spring within the handle urges the hammer axially toward the shaft. The hammer passes through a ball-collar, which is axially translatable to remove retention between the hammer and the plunger, allowing the plunger to pass through the hammer bore, so that the hammer is rapidly axially translated by a main spring and strikes the plunger, imparting an impact force to the shaft.Type: GrantFiled: March 27, 1995Date of Patent: May 13, 1997Assignee: Harris CorporationInventors: Michael M.

Patent number: 4526070Abstract: In a pliers-type tool having a stationary first handle and a second handle pivotally movable relative to the first handle, a slidable jaw carrier is movable along a rectilinear guiding track in a body member due to the pivotal movement of the second handle. The first handle is fixed to the body member. The second handle is in engagement with a toggle mechanism including a driver arm which, in turn, is pivotally attached at a stationary location to the body member. When the second handle is pivoted, the driver arm contacts, in a gliding manner, the jaw carrier and moves it rectilinearly in the guiding track. The driver arm extends transversely of the rectilinear guiding direction of the guiding track. Forces acting through the driver arm in the direction transversely of the rectilinear direction of the guiding track are prevented from affecting the movement of the jaw carrier. The second handle can be connected to the first handle by a connecting link.Type: GrantFiled: August 25, 1983Date of Patent: July 2, 1985Assignee: C. A.
