A work stop for use on a machine vise is received in a jaw plate for such vise and is securely locked in position. The work stop is fixed in a groove that is machined into a top edge of the jaw plate or jaw, with a member extending over the edge of the jaw plate and adjacent the face of the jaw plate that is used for clamping, a workpiece. This permits the workpiece to be slid against the stop before being clamped. The jaw plate is removably mounted onto a fixed jaw, and is located precisely relative to the fixed jaw so that the jaw plate with the work stop attached can be removed, and then replaced when the same part is to be machined again.

A double vise using a single actuating screw with a self-setting preload arrangement includes a vise base, a center fixed jaw and a pair of movable jaws which are movable toward and away from the center fixed jaw. The movable jaws being actuated with the vise screw. The loads on the vise screw from the jaws being reacted initially by springs that apply a resilient preload against a workpiece in either one of the movable jaws. One jaw is driven with a sleeve rotatably mounted on a cylindrical section of the vise screw and driven through a load release clutch. The springs are mounted on a vise screw support housing that is slidably mounted on the vise base and which provides automatic adjustment of the vise jaws to clamp different size workpieces in the jaws. The sleeve has a threaded section for operating one of the jaws.

A device for machining a plurality of workpieces. The device having a plurality of identical independent machining assemblies attached on a rotating carousel plate such that one operator can unload and load a workpiece at one machining assembly while the other machining assemblies are machining the workpiece therein such that when a machining assembly returns from rotation on the carousel plate it is finished machining.

In a milling machine or the like having a socket for a removable arbor having, a frictional engaging member is positioned around the removable arbor such that the frictional engaging member is positioned between the removable arbor and the spindle when the arbor is inserted into the spindle. A flange is positioned below the clamping member on the removable arbor to limit the downward motion of the clamping member and to communicate with the spindle to limit the inward placement of the arbor within the spindle. A sleeve connects the arbor to a drawbar and a drive collar engages the arbor with the spindle for rotation.

A two-station, single action device has a body, with a fixed center block forming oppositely facing fixed jaws. At opposite ends of the body, movable jaws are moved toward and away from the fixed center block simultaneously using an actuator drive. The actuator drive has a longitudinal actuator axis and a first member joined to the first movable jaw and a second member joined to the second moveable jaw. A longitudinal power drive joined to the first and second members drives the first and second members in opposite axial directions to move the movable jaws simultaneously toward the fixed jaw. The first member and the second member further rotate about the longitudinal actuator axis in a first rotatable direction to move the movable jaws simultaneously toward the fixed jaw and rotate in a second rotatable direction to move the movable jaws simultaneously away from the fixed jaw.

A machine vise that can serve multipurpose uses is constructed utilizing a cast base made so that it can be easily mounted for NC machining, or mounted on a swivel base, and can be used mounted on its sides or on one end. The cast base is made to simplify clamping to a tool table by providing an accessible ledge for clamping along the sides and ends. The ledge also provides a coolant drain trough. A support for the distal end of the vise screw is mounted to simplify manufacturing without losing precision operation. The same vise body can be adapted for use with interchangeable screws for manual operation of a movable jaw from either end of the vise or using a hydraulic actuator for clamping the movable jaw.

A two station, single action vise has a body, with a fixed center block forming oppositely facing fixed jaws, and movable jaws at opposite ends of the body that are moved by operation of a vise screw toward one of the respective oppositely facing fixed jaws in the center of the body. The vise screw is spring centered and will yield to apply a preclamp with one of the jaws onto a piece part. The movable jaws are shown operated by a vise screw that has left-hand threads for operating one of the movable jaws and right-hand threads for operating the other movable jaw, so that as the screw is rotated both movable jaws move simultaneously toward the center block forming the fixed jaws. In this way two work pieces can be clamped by the movable jaws against the center fixed jaw. In order to preclamp piece parts under a spring load the screw is moved so it can shift axially slightly under spring load after preclamping one part until both movable jaws are positioned to clamp their respective piece parts tightly. The vise screw also can be adjusted axially relative to the vise body to shift one movable jaw relative to the fixed jaw to a different position than the first jaw for purposes of permitting different size parts to be clamped by the respective jaws.

A carriage drive apparatus positions a carriage along a guide rail. First and second front drive rollers are rotatably mounted on a carriage drive housing on opposite sides of a nonrotating guide rail. The first and second front drive rollers are adapted to frictionally engage the guide rail. Third and fourth rear drive rollers are also mounted on the carriage drive housing on opposite sides of the guide rail. The third and fourth rear drive rollers are adapted to frictionally engage the guide rail. A motor is mounted on the carriage drive housing and is coupled to the front and rear drive rollers. The motor is used to drive the carriage drive housing along the guide rail. A sensor is used to sense the position of the carriage housing along the guide rail. The drive can be disengaged from the drive rail while the sensor remains engaged to permit teaching the controls various stop positions while manually moving the carriage drive housing.

A blade sharpener includes a handle to which first and second sharpening members are pivotally attached. The handle has first and second receiving slots for the first and second sharpening members, each slot being on a side opposite the other within the handle. The sharpening members are capable of pivoting from a slot engaging position to an upwardly inclined position, the upwardly inclined position being defined by engagement of a stop within the handle. The sharpening members are inclined in opposite directions resulting in their upper portions being in a spaced relationship. When the blade sharpener is not in use, the sharpening members are pivoted into their respective receiving slots forming a compact unit for storage.

A bench vise which incorporates a self locking fixed jaw operating with a pair of interlocking surfaces reacting as the fixed jaw is loaded. As the workpiece is tightened down, the jaw tends to be forced downwardly against the sliding portion of the vise to tightly lock the workpiece being held. The reaction of the load is carried directly into the support shaft for the fixed jaw, which also forms a swivel member for the vise.
