摘要： An automatic, push-to-start, fluid-operated screwdriver is disclosed including a magazine providing a supply of fasteners so that only a source of fluid pressure is required for operation. A control valve is responsive to push-to-start actuation for automatically initiating a series of steps including (a) commencing operation of a fluid operated motor, (b) terminating operation of the motor when a predetermined torque level is applied to the fastener, (c) causing a subsequent fastener to be released from the magazine, (d) relatively shifting a fastener holder and rotary drive means for allowing the subsequent fastener to enter into alignment with the rotary drive means, (e) causing the holder to secure the fastener in engagement with the rotary drive means, and (f) thereafter returning to the condition prior to step (a) so that the machine is automatically conditioned for driving the subsequent fastener upon push-to-start actuation. The control valve also causes pressurization of a fluid reservoir during operation of the motor. After termination of motor operation, air pressure from the reservoir shifts the holder and rotary drive means for allowing introduction of the subsequent fastener, the holder and rotary drive means thereafter being returned to secure the subsequent fastener in engagement with the rotary drive means. The screwdriver also includes a magazine mounting alternate threaded fasteners with their ends in opposing relation, a gate assembly releasing individual fasteners from the magazine in uniform alignment.

摘要： The air tool of this invention features a shut-off valve in a motor inlet passage with an air bias compartment at one end of the valve and a motor pressure compartment at an opposite end of the valve directly communicating with the inlet to the motor. The air bias compartment has adjustable air bleed means for selectively reducing the pressure in the air bias compartment from a predetermined line pressure to a desired operating pressure at a constant percentage less than the predetermined line pressure. To establish the predetermined line pressure of the air supplied to the motor and to the air bias compartment of the shut-off valve, a stall torque regulator is provided upstream of the shut-off valve. This regulator serves to maximize the flexibility of the tool by providing for the adjustment of the tool to a given range of pressure and torque at which the motor will shut off but without undesirably affecting the free running speed of the motor within that given range.
摘要翻译：本发明的气动工具具有电动机入口通道中的截止阀，在阀的一端具有空气偏压室，在阀的相对端处的电动机压力室与电动机的入口直接连通。空气偏置隔室具有可调节的排气装置，用于以小于预定管线压力的恒定百分比选择性地将空气偏压室中的压力从预定管线压力降低到期望的操作压力。为了建立供给电动机和关闭阀的空气偏置室的空气的预定的管路压力，在截止阀的上游设置失速转矩调节器。该调节器通过将工具的调节提供给给定范围的压力和转矩，使电动机关闭，但不会不期望地影响在给定范围内的电动机的自由运行速度，从而使工具的灵活性最大化。

摘要： A non-impacting nut running pneumatic tool in which torque pulses are transmitted by an oscillating air motor through a one-way clutch and reduction gearing to the work. A torque responsive cam clutch member responds to a predetermined delivered torque to cause stalling of the motor by blocking off escape of exhaust air and to cause discontinuance of further torque transmission to the work by disabling the drive connection. Manually operable adjusting means is provided to regulate the value of torque delivered.

摘要： A torque tool having a rotation transmitting, torque sensing, energy absorbing, non-overriding mechanism interconnecting a motor and a rotatable driven head. The mechanism includes a driven member coupled to the head and a driver coupled to the motor with the driver yieldably biased toward the driven member. The driven member has cam surfaces facing the driver engaged by bearing surfaces on the driver. The cam surfaces on the driven member permit rotation of the driver relative to the driven member and are sloped such that a preselected torque between the driven member and driver results in the rotation and translation of the driver relative to the driven member. The translation is communicated for the release of a valve rod which actuates a valve to shutoff the motor. The kinetic energy causing relative rotation after shutoff of the motor is stored and dissipated by springs.

摘要： A pneumatically powered tool for setting of threaded fasteners, having an axially movable clutch assembly and a fastener drive spindle both of which are coupled for rotary motion to effect fastener run-up. Upon attainment of a predetermined torque load on the drive spindle, the clutch assembly and drive spindle are intermittently uncoupled by action of a ball being forced up a cam ramp, whereupon a latch pin is activated to initiate seating of an air inlet valve, thus terminating tool operation.

摘要： A power wrench is shown which has a magnetic clutch that releases at a pre-determined torque. The clutch comprises a driving clutch member with a permanent-magnetic sleeve in which a permanent-magnetic sleeve of a driven clutch member is disposed. The permanent-magnetic sleeves are radially magnetized and magnetically inter-coupled through a radial clearance. The driving clutch member is coupled directly to the motor and the driven clutch member is coupled to an output shaft of the wrench through a gear-down mechanism.

摘要： A speed shifting mechanism for a pneumatic wrench or nutsetter comprises a planetary gear arrangement in the drive mechanism of the wrench in which the planet gear carrier is connected to the driver clutch member of a torque responsive clutch and the planetary ring gear is mounted in a one way clutch to provide for unidirectional rotation of the ring gear. The torque responsive clutch is of the sloping tooth type and the driving clutch member is connected to a piston having opposing faces and fitted in the tool housing to form opposed fluid chambers. Pressure fluid is admitted to one of the chambers at a controlled pressure to act on the piston for holding the clutch in the engaged condition. Movement of the driving clutch member at torque causes pressure fluid at the controlled pressure to be vented and the opposite chamber to become pressurized thereby acting on the clutch to disengage and enable the planetary gear arrangement to become operative to reduce the output speed of the wrench.
