Abstract
The present invention involves a high power vacuum attachment apparatus with infinite adjustability and includes a housing with side walls, a top and a back, and with an open front and an open bottom. A gate located within the housing divides it into two compartments and is slidably mounted so as to be moved up and down within the housing. The top of the housing has an orifice through which an adjustment mechanism passes and is connected to the gate. Preferably, the side walls have a greater width at the open front than at the rear wall so as to taper rearwardly. Also, this attachment may include a vacuum pipe connected to the housing which functions as a handle, a vacuum line and may include an adjustable air valve. In preferred embodiments, squeegees are included along the bottoms of the housing walls.
Claims18
An attachment for a high power fluid vacuum system, which comprises:
- (a) a housing having a left side wall, a right side wall, a rear wall connected to said left side wall and said right side wall, a top connected to all of the aforesaid walls to seal off its sides, top and rear, and having an open front and an open bottom, said front and said bottom being respectively substantially vertical and substantially horizontal, said rear wall having an evacuation orifice for connection to a vacuum system pipe;
- (b) a gate dividing said housing into a forward compartment and a rearward compartment, and mounted within said housing between said open front and said rear wall, and being adjustably movable from the open bottom level upwardly so as to create a control for setting a passageway between said gate and any surface upon which said housing may rest to a predetermined size, and so as to thereby control vacuuming of shallow bodies of fluid, and so as to create a safety wall between said open front and said rear wall;
- (c) an adjustment mechanism connected to said gate through the top of said housing so as to permit manual opening and closing adjustment of said gate from outside of said housing.
