摘要： A pneumatic air feed peck drill adapted to drill in repetitive cycles including a rapid advance phase, a slower drilling phase, and a rapid retract phase. The rapid advance phase ends and the drilling phase begins at a set back position, an adjustable distance from the workpiece, to minimize a drill bit and workpiece damage. The drill includes a drill motor and feed cylinder powered by air to rotate and advance and retract the drill motor. The drill motor and feed cylinder is coupled with an air and mechanical control system including a hydraulic feed control unit having a piston rod coupled with the drill motor to dampen the advance of the drill motor during the drilling phase and to release for rapid retract and advance phases. A brake is mounted for control of the feed control unit piston rod to releasably engage the piston rod during the retract phase to limit the movement of the rod to an adjustable set back distance controlled by a set back nut limiting the distance the brake may move relative to the feed control unit when the brake engages the piston rod. A pneumatic system including a volume chamber is coupled with the air system to control the peck cycle rate. One embodiment of the drill includes an auxiliary thrust and retract piston assembly while another embodiment has only the primary drill motor and feed cylinder. A further embodiment includes an interrupt valve in the pneumatic system to disable the drill when a safety shield is removed. The safety shield may be transparent plastic with incremental markings to aid in making adjustments.

摘要： The automatic feed drill includes a spindle mounted therein for rotating in reciprocating movement. The spindle is rotated by spindle rotation gear that is engaged with the main drive gear which is ultimately driven by an air motor or the like. The feed and retraction movement (reciprocation) is caused by a spindle feed gear that is threaded onto the spindle. The spindle feed gear is engaged with a feed gear which, during feed movement, is driven by the main drive gear, and during retraction movement, is shifted into a position wherein the feed gear is prevented from rotating. The spindle also carries a collar or other abutment that engages a shift lever at the end of the feed movement. The shift lever is moved by the collar, and, due to its interconnection with the feed gear, moves the feed gear out of engagement with the main drive gear and into the position wherein it is prevented from rotating. The apparatus also includes a yieldable stop device that holds the feed gear stopped during retraction movement. In the event that excessive torque is encountered, such as by a lower collar on the spindle engaging the housing, the yieldable stop member rotates at the same speed as the spindle feed gear and thus, prevents further retraction of the spindle and avoids damage to the drill.
摘要翻译：自动进给钻头包括安装在其中以用于往复运动的旋转的主轴。主轴由与主驱动齿轮接合的主轴旋转齿轮旋转，主驱动齿轮最终由气动马达等驱动。进给和退回运动（往复运动）是由主轴进给齿轮旋转到主轴上引起的。主轴进给齿轮与进给齿轮接合，在进给运动期间，主进给齿轮由主驱动齿轮驱动，并且在回缩运动期间，进给齿轮被移动到防止进给齿轮旋转的位置。主轴还带有在进给运动结束时与换档杆接合的轴环或其他支座。变速杆由轴环移动，并且由于与进给齿轮的互连，使进给齿轮与主驱动齿轮脱离接合并进入其被阻止旋转的位置。该装置还包括可收回的停止装置，其保持在收回运动期间停止的进给齿轮。在遇到过大扭矩的情况下，例如通过主轴上的下轴环接合壳体，可屈服的止动构件以与主轴进给齿轮相同的速度旋转，并且因此防止主轴的进一步缩回并避免损坏钻头。

摘要： A positive feed drill assembly having an air powered motor and an automatic drill feed and retract mechanism with a normal feed, drill, and retract sequence of operation is provided with an improvement to control the number of times the drill can be used to make a hole with a particular cutter. The improvement includes an apparatus associated with the automatic feed and retract mechanism for sensing the cycle of each drilling operation. A counter functioning with the sensing apparatus counts the number of drilling operations. A comparator associated with the counter compares the accumulated number of drilling operations with a predetermined number. A signaling apparatus connected with the counter provides a signal to the operator when the drill assembly has performed the maximum number of drilling operations for that cutter so the operator can replace the cutter before using the drill assembly again.

摘要： The invention relates to a torque-limiting clutch for use in combination with a positive feed drill that has a reversible motor and reversible driving means. A preferred use of the clutch is in combination with a drill that has a reversible motor rapid advance system. The clutch provides direct drive in a forward mode and is torque-limiting in a reverse mode so as to protect the gears from breaking due to excessive torque while the gears are turning in reverse during the rapid advance mode. In the reverse mode, the torque-limiting clutch protects the drill bit as it bears on the workpiece and prevents unscrewing of the drilling and mounting components. In a preferred embodiment the clutch is mounted on a shaft and is comprised of two clutch jaws that drive through lugs mounted on the jaws. The lugs provide direct drive in a forward rotation, but are shaped so as to allow the jaws to disengage when the torque is excessive in a reverse rotation.

摘要： An air tool includes a housing containing an air motor with a shaft rotatable about a longitudinal axis and connectable to an implement for working the surface of a workpiece. Power handle and idle handles have upper and lower ends connected to the housing at angularly spaced locations. Air power is supplied to the motor by an air passage extending through the power handle to an intake at the top of the housing. The upper and lower connections of the handles to the housing have axes extending generally perpendicular to each other and vibration insulators prevent metal to metal contact with the housing. One of the vibration insulators also is used in sealing against the loss of power air before entering the motor. Between their upper and lower ends, the handles are slanted at an angle of about fifteen degrees (15.degree.) relative to the axis of the tool.

摘要： A gear shifting power tool (10) includes a rotatably-driven, torque-responsive, gear shift device (30). Rotatably-driven, torque-responsive, gear shift device (30) may include drive spindle (38), plunger (54) positioned within drive spindle (38). Drive spindle (38) has first hole pair (44) and second hole pair (46) in which first ball pair (48) and second ball pair (50) contact plunger (54). Drive clutch member (32) is drivably engaged to drive spindle (38) through ball screw arrangement (64). Drive clutch member (32) disengages from driven clutch member (34) in response to a resistive torque overcoming torque spring (40). Inertial device (62) forces first ball pair (48) into one end of plunger (54) which forces plunger (54) towards reset spring (60). Plunger (54) forces second ball pair (46) into inner axial groove (36) of drive clutch member (32) and prevents drive clutch member (32) from engaging driven clutch member (34) until all rotation ceases.

摘要： A powered hand tool as a housing containing an air pressure driven motor with an output spindle extending from a work side of the housing and a work device such as a grinding wheel mounted thereon. A guard is mounted with the work side of the housing and at least partially surrounds the work device or grinding wheel. A handle mounted with the housing is provided for an operator to hold the tool. An air pressure flow control valve is mounted in the handle and includes a valve actuator member extending from the handle. An actuating lever is secured to the housing by a removable lever mount located in a locking groove in the housing and held in place by a portion of the guard. With the guard in place the actuating lever mount is positioned for hand actuation upon grasping the handle. Removal of the guard from the housing releases the lever mount and disables the tool by allowing the lever mount to slide freely from the locking groove thus removing the actuating lever from the tool and discouraging unsafe operation of the powered hand tool with the work device guard removed.
