Abstract

A linear transfer stroking boom has a housing suspended from a support which may be the travel carriage of an overlying longitudinally reciprocal shuttle. A cylinder assembly is mounted within the housing and includes a reciprocal piston rod on a longitudinal axis. A plurality of parallel spaced guide rods are slidably mounted upon and extend through the ends of the housing and outwardly thereof. Boom mount plates span the ends of the guide rods with the piston rod secured to one boom mount plate. A pair of parallel spaced boom extension arms are removably mounted upon the boom mount plates and extend forwardly of the housing. A workpiece gripping assembly spans and depends from the free ends of the boom arms. Reciprocal movement of the piston rod effects corresponding longitudinal movements of the boom arms in the same direction as and simultaneous with feed corresponding movements of the travel carriage.

Dependent claims

A linear transfer stroking boom comprising an elongated housing having a longitudinal axis suspended from a support and having spaced end plates;

an elongated cylinder assembly within said housing mounted upon said end plates including a reciprocal piston rod on said axis movable through one of said end plates;
a plurality of spaced guide rods parallel to said axis extending through said housing slidably mounted upon said end plates and extending outwardly thereof;
a pair of upright boom mount plates outwardly of said end plates spanning and receiving the ends of said guide rods and secured thereto;
said piston rod being connected to one of said boom mount plates, whereby reciprocal movements of said piston rod effects reciprocal movements of said guide rods and boom mount plates relative to said housing;
apertured longitudinally spaced aligned boom mount brackets removably mounted upon and aligned with the ends of said boom mount plates respectively and secured thereto;
a pair of parallel boom extension arms extending through aligned boom mount brackets and secured thereto and extending forwardly of one of said boom mount plates;
and a workpiece gripper assembly spanning and depending from the free ends of said boom arms.
