Appl. No.:

10/209839

Inventors:

Robert J. Centner - Frankfort IL

Assignee:

Illinois Tool Works Inc. - Glenview IL

International Classification:

B23K 900

US Classification:

21913762

Abstract:

A welding system having a welding gun with a handle. The handle is adapted to cool the interior of the handle with a flow of air. The handle may be adapted with a plurality of ventilation holes to enable air to pass through the handle. The handle may have a plurality of ribs disposed along the interior of the handle to direct air flow around a conductive member disposed therein. The ribs may be adapted to direct the air to flow radially and/or longitudinally around the interior of the handle.

Appl. No.:

12/166706

Inventors:

Robert J. Centner - Frankfort IL, US

Assignee:

Illinois Tool Works Inc. - Glenview IL

International Classification:

B23K 9/00
B23K 9/10

US Classification:

219136, 21913731

Abstract:

A neck for a welding torch includes a rigid, non-tubular, elongated member having opposite first and second ends. The first end is connectable to a rear portion of the welding torch. The second end is connectable to a welding tip portion of the welding torch. The member locates and holds the welding tip portion in a precisely given location, and does not communicate welding power, welding wire, shielding gas, or cooling water between the first and second ends.

Filed:

Mar 15, 2006

Appl. No.:

11/375788

Inventors:

Robert Centner - Frankfort IL, US

International Classification:

B23K 9/12

US Classification:

219137620

Abstract:

A removable cooling collar is provided for cooling the nozzle of a welding nozzle. This collar includes first and second parts in fluid communication with a chamber that extends circumferentially within a hollow structure. Cooling fluid circulating through the chamber facilitates dissipation and/or extraction of heat in the nozzle, in turn reducing the likelihood of weld splatter adhesion on the nozzle.

Appl. No.:

9/076527

Inventors:

Steven Allen Kersten - Chicago IL
Robert Joseph Centner - Matteson IL

Assignee:

WaterSaver Faucet Co. - Chicago IL

International Classification:

E03C 110

US Classification:

137218

Abstract:

A vacuum breaker for use in a fluid supply system is provided. The vacuum breaker comprises a body having an interior, a fluid inlet, a fluid outlet, and an atmospheric air vent. The body is adapted to permit fluid to flow through the interior from the fluid inlet to the fluid outlet. A first seat disposed within the interior of the body. A bonnet having a second seat communicates with the air vent and the interior. A displacable float cup is disposed between the bonnet and the first seat. The float cup adapted to be sealingly seated against the second seat when the vacuum breaker is subject to an open flow condition, and to be sealingly seated against the first seat when the vacuum breaker encounters a pressure loss condition. Gaskets are provided to enhance the seal at the first and second seats. Both seats are above a water level within the body of the vacuum breaker.
