    摘要： The invention relates to a press driven work tool module comprising a power unit and a work unit. Each unit comprises a fluid filled cylinder, a piston for reciprocation therein, and a piston rod. Hydraulic fluid within the power stroke displacement space of the power cylinder is in communication with hydraulic fluid in the work displacement space of the work cylinder, and hydraulic fluid within the return displacement space of the power cylinder is in communication with hydraulic fluid within the return stroke displacement space of the work cylinder. The power cylinder is provided with a moving top plate connected to the power piston rod and a spring arrangement for urging the top plate and power piston rod to the return position, such that a drive force acting on the power piston rod moves the power piston and work piston to the power and work ends of the respective cylinders against the spring bias. The system is hydraulic and eliminates the need for pressurized gas, avoiding problems such as contamination, worn seals, loss of pressure over time, and need for recharging.

    摘要： AN IMPACT GUN ADAPTED TO DEFORM THE TUBULAR END OF A FASTENER SECURED TO A SUPPORT, INCLUDING A PLUNGER MEANS SUPPORTED FOR RECIPROCATING MOVEMENT BY THE BODY PORTION OF THE GUN HAVING A SPECIALLY DESIGNED HEAD PORTION ADAPTED TO ENGAGE THE INNER EDGE OF THE FASTENER AND DE FORM THE TUBULAR END RADIALLY OUTWARDLY AND TOWARD THE SUPPORT. THE HEAD PORTION OR ANVIL IS INITIALLY SEPARATED FROM THE PLUNGER OR HAMMER, AND IS GUIDED INTO CONTACT WITH THE END OF THE FASTENER BY A PILOT SUPPORTED FOR RECIPROCATION WITHIN THE HEAD PORTION. THE METHOD DISCLOSED HEREIN INCLUDES DISPOSING A SUPPORTING MEMBER WITHIN THE TUBULAR FASTENER AND IMPACTING THE FASTENER END.

    摘要： The lifting of a drop hammer is controlled by a spool-type valve admitting compressed air into the main cylinder of the hammer. In order for compressed air to be admitted the valve spool is forced from its normal position exhausting the cylinder into a position supplying compressed air to the main cylinder by admitting control air into a region in which its pressure moves the spool against opposition by a spring. After compressed air has been admitted to the main cylinder, at a preselected control position, the control air is exhausted. A slide in the valve is then moved toward the spool and into a stop by air pressure from the cylinder. The spring returns the spool part way toward normal position until it contacts the slide, in which position the cylinder is closed off from the supply of compressed air but is not opened to exhaust. When the air pressure in the cylinder has been reduced by expansion to a predetermined level at which most of its energy is extracted the spool under urging of the spring will push the slide out of the way and the spool back to position to exhaust the cylinder.
