Abstract
An air operated reciprocating tool, including, an air operated double ended piston positioned within a cylinder for reciprocation within the cylinder, a valve assembly in communication with a source of air for controlling the application of the source of air in alternation to opposite portions of the piston for reciprocation of the piston, a shoe member for supporting a tool and with the shoe member mounted for sliding motion, and belt means forming a loop for interconnecting the ends of the double ended piston and the shoe member and with the belt means supported by pulley members located adjacent the ends of the double ended piston and with the reciprocating motion of the double ended piston transmitted to reciprocating motion of the shoe member.
Claims21
An air operated reciprocating tool, including,
- an air operated double ended piston positioned within a cylinder for automatic continuous reciprocation within the cylinder,
- a valve assembly operatively actuated by the piston and in communication with a source of air for automatically alternating the control of the application of the source of air to opposite portions of the piston for producing automatic continuous reciprocation of the piston,
- a shoe member for supporting a tool and with the shoe member mounted for sliding motion, and
- belt means forming a loop for interconnecting the ends of the double ended piston and the shoe member and with the belt means supported by pulley members located adjacent the ends of the double ended piston and with the automatic continuous reciprocating motion of the double ended piston transmitted to automatic continuous reciprocating motion of the shoe member.
An air operated reciprocating tool, including,
- an air operated double ended piston positioned within a cylinder for automatic continuous reciprocation within the cylinder and with the double ended piston including two spaced piston halves having inner surfaces and interconnected by a rod located along a center line for the piston halves,
- a valve assembly located within the space between the spaced piston halves and operatively actuated by the inner surfaces of the spaced piston halves and concentric with the rod and along the center line and in communication with a source of air for automatically alternating the control of the application of the source of air to the inner surfaces of the two spaced piston halves of the piston for producing automatic continuous reciprocation of the piston and with the valve assembly including a fixed valve body and a movable valve member and with the movement of the valve member relative to the valve body providing the automatic alternation in air to the inner surfaces of the two spaced piston halves and with the movement of the valve member directly actuated by the inner surfaces of the spaced piston halves,
- a shoe member for supporting a tool and with the shoe member mounted for sliding motion, and
- means interconnecting the double ended piston and the shoe member and with the automatic continuous reciprocating motion of the double ended piston transmitted to automatic continuous reciprocating motion of the shoe member.
