Abstract
Abstract Apparatus for squeeze testing the side walls of glass containers by passing them successively between the periphery of a wheel and an opposed shoe. The shoe is shaped to provide a converging entrance portion, a diverging exit portion, and an intermediate arcuate portion concentric with the wheel. The shoe is urged toward the wheel to apply squeezing pressure by air pressure actuated means which includes an air reservoir to cushion the squeezing force. The shoe is mounted to move slightly downwardly toward the wheel and slightly upwardly away from the wheel so that containers passing between the shoe and the wheel periphery move the shoe away from the wheel and thus lift the containers from a conveyor.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
206 words
Apparatus for squeeze-testing glass containers comprising a wheel mounted for rotation on a vertical axis and a shoe member directed toward the periphery of said wheel and adapted to apply squeezing pressure against the side wall of a container engaged between said shoe and the periphery of said wheel, the surface portion of the shoe facing said wheel periphery being generally vertical and comprising a medial arcuate portion concentric with said wheel and an entry portion diverging outwardly from said wheel periphery to form a gradually converging entry portion for glass containers disposed to receive containers moving along a conveyor, said entry portion being integral with and forming a smooth continuation of said arcuate surface portion whereby squeezing pressure is applied to container side walls gradually and without impact, means for rotating said wheel to roll said containers against said shoe to move them through said apparatus and apply squeezing pressure throughout the peripheries of said containers, air pressure actuated means acting against said shoe to urge the same yieldably toward said wheel periphery, and air pressure regulating means for supplying an adjustable predetermined pressure to said pressure actuated means to apply a predetermined squeezing force against containers passing between said wheel periphery and said shoe.
Claim 2
Dependent Claim
206 words
Apparatus for squeeze-testing glass containers comprising a wheel mounted for rotation on a vertical axis and a shoe member directed toward the periphery of said wheel and adapted to apply squeezing pressure against the side wall of a container engaged between said shoe and the periphery of said wheel, the surface portion of the shoe facing said wheel periphery being generally vertical and comprising a medial arcuate portion concentric with said wheel and an entry portion diverging outwardly from said wheel periphery to form a gradually converging entry portion for glass containers disposed to receive containers moving along a conveyor, said entry portion being integral with and forming a smooth continuation of said arcuate surface portion whereby squeezing pressure is applied to container side walls gradually and without impact, means for rotating said wheel to roll said containers against said shoe to move them through said apparatus and apply squeezing pressure throughout the peripheries of said containers, air pressure actuated means acting against said shoe to urge the same yieldably toward said wheel periphery, and air pressure regulating means for supplying an adjustable predetermined pressure to said pressure actuated means to apply a predetermined squeezing force against containers passing between said wheel periphery and said shoe.
Claim 3
Dependent Claim
248 words
Apparatus for squeeze-testing glass containers comprising a wheel mounted for rotation on a vertical axis and a shoe member directed toward the periphery of said wheel and adapted to apply squeezing pressure against the side wall of a container engaged between said shoe and the periphery of said wheel, the surface portion of the shoe facing said wheel periphery being generally vertical and comprising a medial arcuate portion concentric with said wheel and an entry portion diverging outwardly from said wheel periphery to form a gradually converging entry portion for glass containers disposed to receive containers moving along a conveyor, means for rotating said wheel to roll said containers against said shoe to move them through said apparatus and apply squeezing pressure throughout the peripheries of said containers, air pressure actuated means acting against said shoe to urge the same yieldably toward said wheel periphery, air pressure regulating means for supplying an adjustable predetermined pressure to said pressure actuated means to apply a predetermined squeezing force against containers passing between said wheel periphery and said shoe, and mounting means for said shoe pivoted about an axis generally Parallel to the direction of movement of the containers for movement of said shoe toward and away from said wheel, said movement of said shoe being arcuately downward toward said wheel and arcuately upward away from said wheel, whereby entry of a container between said wheel and said shoe moves the latter arcuately upward to raise the container from said conveyor.
Claim 4
Dependent Claim
