Abstract
A back pack for carrying a gas operated blower. The back pack has a frame and straps for supporting the frame on the back of an operator. The frame has a dual wall construction forming an internal fuel storage tank. Thus, the blower does not need a separate fuel tank. This reduces the weight and cost of the back pack and blower.

A back pack for use in carrying a machine having an internal combustion engine, the back pack having a one-piece frame and straps for removably supporting the back pack and machine on an operator, the one-piece frame comprising:
- a first vertical section adapted to be positioned against a back of an operator;
- and
- a second horizontal section adapted to have the machine mounted thereon, the second section extending generally perpendicularly from the first section, being unitarily formed with the first section, having an integral storage area therein for supplying fuel to the engine and, having a dual wall structure with a space formed between the walls that defines the fuel storage area, wherein portions of the walls come together at selected locations of the second section and, the second section has holes through the walls at some of the selected locations for fasteners to mount the machine to the second section.
A back pack comprising:
- a one-piece back pack frame for supporting a blower unit on the back of an operator, the frame being comprised of a molded dual wall structure with a vertical section adapted to be supported against the back of an operator and a horizontal section adapted to support the blower thereon, the frame forming an integral internal fuel storage tank within its dual wall structure at the horizontal section, the storage tank being located throughout substantially the entire horizontal section;
- and
- means for supplying fuel from the tank to the blower.
A back pack frame comprising:
- a vertical section adapted to be supported on a back of an operator;
- a horizontal section adapted to at least partially support a machine having an internal combustion engine thereon;
- and
- means for storing a combustible fuel inside the frame along substantially the entire horizontal section, the means for storing comprising the frame having a molded dual wall construction with a space between portions of the walls such that the space between the walls can function as a fuel tank to store fuel for use with the engine being carried on the frame.
