Abstract
A compressed gas cylinder assembly is disclosed which includes a metallic cylinder body having an upper end portion with handles and a flow control valve, and a lower end portion with a convex surface from which depends a lower support ring. A non-conductive annular collar surrounds the lower support ring of the cylinder body, and a conductive foot ring connects the annular collar to the lower support ring of the cylinder body, providing a conductive path to ground for the metallic cylinder body.
Claims23
A gas cylinder assembly comprising:
- a) a cylinder body having an upper end portion including a flow control valve and a lower end portion from which depends a lower support ring;
- b) an annular collar surrounding the lower support ring of the cylinder body;
- and
- c) a foot ring adapted and configured to connect the annular collar to the lower support ring of the cylinder body.

A gas cylinder assembly comprising:
- a) a metallic cylinder body having an upper end portion including handles and a flow control valve and a lower end portion with a depending lower support ring that includes an annular wall having a radially outwardly projecting support flange;
- b) a non-conductive annular collar surrounding the lower support ring of the cylinder body, the annular collar having a plurality of circumferentially spaced apart radially inwardly facing engagement struts for engaging the support flange of the lower support ring about the periphery thereof;
- and
- c) a conductive foot ring adapted and configured to connect the non-conductive annular collar to the lower support ring of the metallic cylinder body, the foot ring defining an annular channel for accommodating the engagement struts of the annular collar and the lower support ring of the cylinder body, wherein the conductive ring is in intimate contact with the lower support ring of the cylinder body, to provide a conductive path to ground for the cylinder body.
1 more element
A gas cylinder assembly comprising:
- a) a cylinder body having a lower end portion with a convex surface area that includes a lower support ring;
- and
- b) an annular collar connected to the lower support ring of the cylinder body and including a plurality of circumferentially spaced apart upstanding shock absorbing fins dimensioned and configured to interact with the convex surface area of the lower end portion of the cylinder body.
