Abstract
Abstract A Duct and Blower Arrangement is herein described which duct may be formed to define an opening in a side wall portion thereof to receive the blower. A flange may be formed in the duct for operatively supporting the blower within the duct, upon inserting the blower therein. A closure member may be connected with the blower for covering the opening in response to the proper insertion of the blower into the duct.

Total Claims: 11
Claim 1
Independent Claim
152 words
A duct and blower arrangement comprising: a duct having an openiNg in one end thereof through which air may be moved; said duct having a lateral opening therein for receiving a blower unit; a blower unit movable into and out of said duct through said lateral opening; means on said duct for suporting said unit upon insertion thereof into said duct through said lateral opening; said blower unit having a base which extends transversely across the duct when the unit is inserted into said lateral opening and has an air passage therethrough communicating with said one end of the duct; a blower mounted on said base for moving air longitudinally through said duct past said lateral opening; and a closure member carried by said unit and located at one side of said base in position to close said lateral opening upon insertion of said unit into said duct through said lateral opening.
Claim 2
Dependent Claim
