Abstract

A device for distributing gas near a weld location includes a cap, a funnel, an inlet, and an aperture. The cap includes a sidewall and an annular lip, and defines a reservoir between the sidewall and the annular lip. The annular lip includes a proximal-most edge. The cap defines an opening, and defines a longitudinal axis. The funnel is disposed adjacent a distal end of the cap. The inlet is disposed in mechanical cooperation with the cap. The aperture is disposed through the sidewall of the cap and is in fluid communication with the inlet. The aperture is disposed distally of the proximal-most edge of the annular lip. Gas is configured to flow through the inlet, through the aperture and into the reservoir. The reservoir is configured to allow the gas to uniformly overflow the proximal-most edge of the annular lip and flow distally through the opening defined by the cap.

First claim

What is claimed is:

1. A device configured for distributing gas near a weld location, the device comprising:
a cap including a sidewall and an annular lip, a reservoir defined between the sidewall and the annular lip, the annular lip including a proximal-most edge, the cap defining an opening, having a longitudinal axis extending through a radial center of the opening from a proximal end of the opening to a distal end of the opening;
a funnel disposed adjacent a distal end of the cap;
an inlet disposed in mechanical cooperation with the cap; and
an aperture disposed through the sidewall of the cap and in fluid communication with the inlet, the aperture disposed distally of the proximal-most edge of the annular lip;
wherein gas is configured to flow through the inlet, through the aperture and into the reservoir, and wherein the reservoir is configured to allow the gas to uniformly overflow the proximal-most edge of the annular lip and flow distally through the opening defined by the cap, and
wherein a distal end of the cap is disposed at a non-perpendicular angle with respect to the longitudinal axis.

2. The device according to claim 1 , wherein the funnel is selectively engageable with the cap.

3. The device according to claim 1 , wherein the funnel is configured to selectively engage the cap with a plurality of magnets.

4. The device according to claim 1 , further comprising a first plurality of magnets disposed on a distal end of the cap, and a second plurality of magnets disposed on a proximal end of the funnel.

5. The device according to claim 1 , wherein a proximal end of the funnel is disposed at a non-perpendicular angle with respect to the longitudinal axis.

6. The device according to claim 5 , further comprising a first plurality of magnets disposed on the distal end of the cap, and a second plurality of magnets disposed on the proximal end of the funnel.
