Abstract
An improved support for holding a plurality of nozzles of a compressed air tempering apparatus in individually adjusted axial position, said support comprising an expandable member relative to which each of the nozzles is axially slidable, and mechanism for expanding the expandable member into pressure holding engagement with each nozzle to hold them in their axially adjusted positions.
Claims12
In a compressed air tempering apparatus for sheets of glass, said apparatus including a plurality of blast nozzles for directing air against said glass, means for connecting each of said nozzles to a source of compressed air, and nozzle support means for holding said nozzles in individually adjusted axial position, the improvement wherein the nozzle support means includes:
- a. hollow, flexible, inflated expandable means for engaging against the sides of each of said nozzles and with respect to which said nozzles are axially slidable;
- and
- b. control means for expanding said expandable means laterally into pressure holding engagement with the sides of said nozzles to hold them in their individually adjusted axial positions.
In a compressed air tempering apparatus for sheets of glass, said apparatus including a plurality of blast nozzles for directing air against said glass, means for connecting each of said nozzles to a source of compressed air, and nozzle support means for holding said nozzles in individually adjusted axial position, the improvement wherein the nozzle support means includes:
- a. expandable means for engaging against the sides of each of said nozzles and with respect to which said nozzles are axially slidable, said expandable means including a sealed, flexible, hollow member having opposite, spaced, flat side walls and isolated openings extending through said member from one side wall to the other in non-fluid communication with the interior thereof, each of said openings receiving one of said nozzles therethrough;
- and
- b. control means for expanding said expandable means laterally into pressure holding engagement with the sides of said nozzles to hold them in their individually adjusted axial positions.
In a compressed air tempering apparatus for sheets of glass, said apparatus including a plurality of blast nozzles for directing air against said glass, means for connecting each of said nozzles to a source of compressed air, and nozzle support means for holding said nozzles in individually adjusted axial position, the improvement wherein the nozzle support means includes:
- a. expandable means for engaging against the sides of each of said nozzles and with respect to which said nozzles are axially slidable, said expandable means including a sealed, flexible, hollow, inflatable, member having opposite, spaced, flat side walls and isolated openings extending through said member from one side wall to the other in non-fluid communication with the interior thereof, each of said openings receiving one of said nozzles therethrough;
- and
- b. control means for expanding said expandable means laterally into pressure holding engagement with the sides of said nozzles to hold them in their individually adjusted axial positions, said control means including pneumatic means for inflating said inflatable member into pressure engagement with each of the nozzles extending through the openings therein.
In a compressed air tempering apparatus for sheets of glass, said apparatus including a plurality of blast nozzles for directing air against said glass, means for connecting each of said nozzles to a source of compressed air, and nozzle support means including plate means having a plurality of holes through which the nozzles slidably extend for individual axial adjustment and a tightening device for holding the nozzles in selected axially adjusted position, the improvement wherein the tightening device of the nozzle support means comprises:
- a. hollow, flexible, inflated expandable means engaging against each of said nozzles at a location adjacent said plate means;
- and
- b. control means for expanding said expandable means laterally of said plate means and into engagement with the nozzles to press them against the wall surfaces of said holes and hold them in their individually adjusted axial positions.
In a compressed air tempering apparatus for sheets of glass, said apparatus including a plurality of blast nozzles for directing air against said glass, means for connecting each of said nozzles to a source of compressed air, and nozzle support means including plate means having a plurality of holes through which the nozzles slidably extend for individual axial adjustment and a tightening device for holding the nozzles in selected axially adjusted position, the improvement wherein the tightening device of the nozzle support means comprises:
- a. expandable means engaging against each of said nozzles at a location adjacent said plate means, said expandable means including at least one flexible, inflatable hollow member engaging against each of said nozzles;
- and
- b. control means for expanding said expandable means laterally of said plate means and into engagement with the nozzles to press them against the wall surfaces of said holes and hold them in their individually adjusted axial positions, said control means including pneumatic means for inflating said hollow member into pressure engagement with each of said nozzles.
