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.

The blowhead mechanism of claim 1 wherein said means for imparting movement includes a cam member mounted loosely on said shaft above said blowhead arm and having a cam track therein, said cam track having an inclined portion and a vertical portion, a cam follower on said shaft positioned in said cam track, the inclined portion of said cam track engaging said cam follower during movement of said blowhead arm from its first to its second position, stop means limiting rotation of said shaft by said cam member whereupon said cam follower will ride down the inclined portion of the cam track as said cam member continues rotation moving said shaft axially.
- 3. The blowhead mechanism of claim 2 wherein said cam member is spring urged from the first to second position and cam actuated from its second to its first position.
