Abstract
A blowhead mechanism for use in a continuous rotary motion press and blow type glass ware forming machine wherein the blowhead is attached to a shaft which is rotatably mounted on the machine by means of an arm and having a loosely mounted annular cam member on said shaft with a cam track therein having inclined and vertical portions, a cam follower mounted on said shaft in a position to engage the track during rotary movement of the shaft and blowhead, means to rotate the cam member, stop means to limit rotation of the said shaft whereby the shaft and the blowhead rotate from a first position to a second position whereat the shaft is moved vertically downward to place the blowhead onto a blow mold and after blowing the glass ware the shaft is moved up and rotated back to its original position.
Claims4
A blowhead mechanism for a glassware forming machine, said mechanism comprising a shaft rotatably mounted on said machine, a blowhead arm attached to said shaft and including at least one blowhead, and means mounted about said shaft and positioned above said blowhead arm for imparting movement to said blowhead arm from a first position to a second position during which said shaft first rotates about its axis and then is moved axially vertically and from a second position to a first position during which the shaft is first moved axially vertically and then rotated about its axis.
