The sleeve carries a pawl and an elastic O-ring which urges an edge portion of the pawl into engagement with the threads of the control bar for enabling one-way movement of the control bar downwardly through the sleeve. An actuator pin is slidably disposed in a bore which extends through the sleeve and is movable downwardly in response to contact with a stop-nut disposed on the bar when the drill press has advanced to a preset depth represented by the position of the stop-nut.

Abstract: A drive shaft rotated by an electric motor is disposed to penetrate through a main body, and a spindle is concentrically mounted at the distal end of the drive shaft so that the rotational force of the drive shaft moving in an axial direction thereof is transmitted to the spindle. A processing drill head is selectively mounted at the distal end of the spindle that is coupled with a piston which is urged to a first position in an axially forward direction of the spindle by the fluid pressure supplied to a cylinder, for executing a processing work and a retreated position at which a hold mode is set. An abutting member is securely fitted to the outer surface of a piston rod, and a ring-shaped magnetic member is further provided to the outer surface of the piston rod in an axially movable manner, this ring-shaped magnetic member always being urged in the retreating direction.

Abstract: A roller hold down device for removable work table which has a pair of rollers which extend transversely across the workpiece mounted on the movable table so as to hold it down and with a pair of cam roller members mounted on either side of the movable table and formed with cam portions so as to engage the rollers at the end of travel so as to force the rollers up away from the workpiece and also so as to prevent the rollers from falling off of the end of the workpiece. The rollers are controlled by hydraulic cylinders which can be actuated to automatically move them to the down position and also to move them to the up position.

Abstract: A replaceable spindle locking system for a power tool enables an operator to replace a lock member without disassembling the tool. An externally-accessible retaining member, such as a washer, is trapped between a ledge located in a housing recess and a shoulder formed on the lock member, which is normally spring-biased out of engagement with a driven member. The coaction of these elements simultaneously and releasably normally retains both the lock member and the retaining member connected to the housing. When it is desired to replace the lock member, the operator depresses the lock member against the urging of the spring until the lock member is out of retaining engagement with the retaining member. Then the retaining member is slideably moved out of engagement with the lock member, thereby allowing the operator to quickly remove it.

A sleeve is threadedly engaged with the screw shaft to be axially moved at the time of relative rotation between the mounting shell and the screw shaft. This sleeve, when axially moved, actuates a transmitting member, supported in the shell, by the wedge action of a cam surface formed thereon, so that a cutting blade support end of a tool secured on the mounting shell is bent to adjust the position of a cutting blade on the tool.

Abstract: The drill includes the usual tool spindle driven by reversible motor, and conventional chucking jaws which rotate with the spindle. The jaws are surrounded by an actuator which is drivingly connected to the jaws, and normally rotates with the jaws when the drill is in use. A manually operable control member on the housing is movable between two operating positions in each of which it holds the actuator against rotation, and consequently causes the spindle to move the jaws to bit-locking or bit-releasing positions, depending upon the direction or rotation of the spindle. Whenever the control member is moved from one to the other of its positions it switches the direction of rotation of the motor.
