Push out for glassware forming machinery

Claim 1

A transfer mechanism for association with glassware forming apparatus for transferring glassware from a dead plate to a moving conveyor which is moving in either one of two directions, said transfer mechanism comprising: a. a fluid motor comprising: 1. a combination housing and cylinder having a hollow cylinder body and forward and rear end walls; 2. a reciprocative tubular piston having a piston head at the rearward end and within said cylinder, the fore end of said piston extending through the forward end wall of said housing; 3. a support and guide post for said piston within said cylinder disposed on the longitudinal axis thereof and having one end fixed supported in said rear end wall, said support post being received within the tubular piston; 4. bearing means interposed between said post and said tubular piston; and 5. first and second duct means in said forward and rear walls, respectively; B. a reversible mounting block on which said fluid motor is mounted, said mounting block having: 1. means for mounting said block on an oscillatory drive shaft in one or the other of two positions according to whether said transfer mechanism is to be used for right-hand or left-hand transfer; 2. built-in fluid ducts adapted to communicate with fluidsupply lines which are fixed in position relative to said mounting block, said built-in fluid ducTs including first and second ducts each having a reversing valve therein adjustable to one or the other of two operating positions according to whether the mounting block is to be used in one or the other of said positions to accommodate to right-hand or left-hand transfer respectively, and; C. first and second pivotal means between said first and second duct means, respectively, and said mounting block for pivotally connecting said fluid motor housing to said mounting block to allow for swinging said mounting block pivotally through an arc of 180* to place said mounting block in either one or the other of its two operating positions to accommodate to right-hand or left-hand transfer respectively without disconnecting said mounting block from said fluid motor.
