Abstract
Abstract A swing-away automation workpiece gripper which, at rest, is in one position and when actuated, swings into a second angularly related position and successively engages a workpiece. Its power cylinder support is pivotally mounted on a vertical axis. Attached to the piston rod is a jaw assembly mount with a depending roller adapted to move along a cam slot for angularly positioning the complete assembly followed by an automatic jaw actuation.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
212 words
In a swing-away automation jaw assembly; a base support; an upright pivot stud thereon; a cylinder support block pivoted on said stud adapted for rotation about a vertical axis; a feed and actuator cylinder assembly for a work piece gripper including a cylinder with reciprocal piston rod mounted on said support block, offset from said stud; a jaw assembly guidably mounted upon said support block for reciprocal longitudinal movements relative thereto; said piston rod projecting into said jaw assembly; said jaw assembly including a body and pivotal jaws adapted to engage a work piece, and reciprocal control means connected to said piston rod adapted on movements thereof to control said jaws; said base support and said jaw body comprising a pair of elements; one of said elements having an elongated cam slot formed therein and extending in a direction at an angle to the normal axis of said cylinder; the other of said elements mounting a guide roller nested in and movable with respect to said slot; whereby on initial movement of said piston rod said roller is moved relatively along said slot to the end thereof causing a controlled swing movement of said cylinder assembly and jaw assembly; said piston at the end of said movement adapted to actuate said jaws.
Claim 2
Dependent Claim
212 words
In a swing-away automation jaw assembly; a base support; an upright pivot stud thereon; a cylinder support block pivoted on said stud adapted for rotation about a vertical axis; a feed and actuator cylinder assembly for a work piece gripper including a cylinder with reciprocal piston rod mounted on said support block, offset from said stud; a jaw assembly guidably mounted upon said support block for reciprocal longitudinal movements relative thereto; said piston rod projecting into said jaw assembly; said jaw assembly including a body and pivotal jaws adapted to engage a work piece, and reciprocal control means connected to said piston rod adapted on movements thereof to control said jaws; said base support and said jaw body comprising a pair of elements; one of said elements having an elongated cam slot formed therein and extending in a direction at an angle to the normal axis of said cylinder; the other of said elements mounting a guide roller nested in and movable with respect to said slot; whereby on initial movement of said piston rod said roller is moved relatively along said slot to the end thereof causing a controlled swing movement of said cylinder assembly and jaw assembly; said piston at the end of said movement adapted to actuate said jaws.
Claim 3
Dependent Claim
27 words
In the swing-away jaw assembly of claim 1, said cam slot being formed in said base support, said roller mounted on and depending from said jaw assembly.
Claim 4
Dependent Claim
23 words
In the swing-away jaw assembly of claim 1, said cam slot being on said jaw body, said roller mounted on said base support.
Claim 5
Dependent Claim
39 words
In the swing-away jaw assembly of claim 1, the guide mounting of said jaw assembly including a pair of laterally spaced elongated guide bars secured to and extending rearwardly of said jaw body slidably mounted on said support block.
Claim 6
Dependent Claim
64 words
In the swing-away jaw assembly of claim 1, said reciprocal control means of said jaw assembly including a block guidably mounted on said jaw body, at one end removably and axially interlocked with said piston rod, the jaws having angularly related control slots therein; and rollers mounted on said block movably mounted in said slots for camming the jaws between open and closed position.
Claim 7
Dependent Claim
52 words
In the swing-away jaw assembly of claim 1, said jaw assembly including a mounting body having a bore receiving said piston rod, said jaw body including a rearwardly extending annular flange; and locking plates with undercut recesses therein mounted on said mounting body receiving said jaw body flange and adjustably secured thereto.
