Abstract: A reversible d.c. torque motor advances and retracts a cone mechanism for radially expanding and contracting the stones of a tool for honing a bore in a workpiece. The motor is adapted to advance the cone mechanism at three different speeds so as to effect expansion of the tool first at a rapid traverse rate, then at a slower coarse feed rate and then at a still slower fine feed rate. Pulses representative of changes in position of the cone mechanism are routed to and are counted by a reversible counter which causes the cone mechanism to retract to different starting positions as the stones of the tool wear and reduce the effective diameter of the tool.

Abstract: This invention relates a twist set ratchet handle characterized by manipulating two controlled bevel wheel assemblies which mesh with each other and run clockwise and counter clockwise so that the ratchet head can be operated by turning the handle only or by turning the handle and the ratchet holder together. So it is a new, exquisite, convenient, multi-purpose ratchet handle.

Abstract: 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.

Abstract: A device for setting the position of a workpiece relative to the endless abrasive belt of an abrasive grinding machine. The device employs a first sensor that can be extended to engage and sense the position of the endless abrasive belt when it is at rest. The device also utilizes a second sensor that can be moved to a position of engagement with the workpiece when it is at rest on a workpiece conveyor. The first and second sensors are constructed and arranged so that the position of one is mechanically related to the position of the other. A movable indicator senses the position of one of the first and second sensors and indicates such position relative to a reference position. The workpiece conveyor can be raised or lowered until the indicator is in the reference position, at which point the distance between the second sensor and the workpiece conveyor corresponds to the distance between the grinding portion of the endless abrasive belt and the workpiece conveyor.
