  • Patent number: 4387502
    Abstract: A tool changer for forging machines or the like is disclosed. The tool changer includes a carriage which is manually movable along a track between positions over a forging machine and a position over a tool storage area. Detents are provided to give an indication when the carriage is properly positioned at each station where a tool changing operation is required. A power lift supported by the carriage is turn supports a tool head for vertical movement. Mounted on the lift is a tiller which extends laterally from the tool changer. Controls for the lift are mounted on the tiller. The tiller and the controls mounted thereon are conveniently located to permit the operator to move the tool changer from an operator's position intermediate the machine and tool storage area and to control the operation of the tool changer from such position. A camming system operates to accurately position the tool changing head as it is lowered into an operative position at each work station.
