Abstract:

A suspended ceiling grid beam is provided that has an increased beam height to provide enhanced resistance to downward deflection. The beam has a cross-section generally in the form of an inverted T, with a central web, a pair of panel support flanges extending from one edge of the web, and a reinforcing bulb extending from the other edge of the web. The reinforcing bulb has a generally planar, fin-like structure extending therefrom opposite to and generally co-planar with the central web.

International Classification:

E04B 9/18

E04B 1/38

US Classification:

5250605, 5250607

Abstract:

A runner for a suspended ceiling grid is roll-formed from a single strip of sheet metal so as to have a generally symmetrical appearance about a vertical center line, with a double vertical web and a double-thickness flange for supporting ceiling tiles. The bottom surface of the flange is continuous across its exposed surface, so that there is no visible juncture of the opposed flanges with the double web when viewed from below, thus providing an aesthetically more-pleasing appearance.

Appl. No.:

5/685513

Inventors:

Richard D. McClain - Schaumburg IL

Assignee:

Mercury Metal Products, Inc. - Schaumburg IL

International Classification:

F23L 1702

US Classification:

98122

Abstract:

An engine exhaust rain cap of the type which is adapted to be clamped to an upstanding exhaust pipe and including a cover secured to a corner of a balance arm body which is pivotally mounted on the ears of the clamp. The balance arm body is a folded sheet metal member whose halves have annular integral outwardly directed extrusions that are brazed to a bearing bushing which in turn is journalled on a bearing member that extends between the halves. The result is a more durable device, especially in the case of heavy duty rain caps.
