Description
This invention relates to a vacuum cleaner which is suitable for picking up particles which are normally too large to be picked up by a conventional vacuum cleaner. The particles may be composed of, for example, excrement of animals and birds, pine cones, twigs and pieces of bark.
The vacuum cleaner of the invention has a central can-ister 10 which is preferably composed of standard polymeric pipe of approximately four inches in diameter. A sleeve 12 is attached to the lower end of the canister.
A cap 14 is removably attached to the lower end of the sleeve and defines the lower wall of the canister. The cap is circular in cross section and has threads formed on its cir-cular outer wall. The threads mate with threads formed on the inside wall of the sleeve. An square extension 16 is formed on the lower wall of the cap to facilitate attachment and removal of the cap by means of a wrench or other tool A second pipe 18, of approximately two inches in diameter is attached to the canister at juncture 20. The angle between the longitudinal axis of the second pipe and that of the can-ister is approximately forty-five degrees. The lower end of the pipe is open at 22 and that end serves as the intake noz-zle of the vacuum cleaner.
An electrically powered or gasoline-powered fan unit or vacuum cleaner 26 is attached to the upper end of the can-ister. The fan unit is of conventional construction and serves to create an air stream which moves at high speed into the in-take nozzle, upwardly through the canister and into the fan unit carrying with it material from outside the cleaner.
A filter 30, preferably in the form of a metallic screen, is positioned in the hollow interior of the canister adjacent to and beneath the fan unit. The mesh size of the screen is selected such that it prevents all particles of a size most likely to be encountered in the intended vacuuming operation from passing through the screen but does not restrict the flow of air. Particles caught by the screen fall to the bottom of the canister where they may be removed by opening cap 14.
In one embodiment, the filter is circular in shape and its edges are attached to the inside wall of the canister so that upwardly travelling air and material carried by it must travel through the screen and cannot bypass it. In another embodiment, the screen is larger than the inside diameter of the canister and is attached to a conventional slider. The slider allows the screen to be slid into and out of the can-ister from the side. In the latter embodiment the screen

2 can be removed for cleaning and for replacement by a screen having a larger or smaller mesh.
A second filter (not illustrated) may be provided for filtering the air expelled by the fan unit. That filter may be composed of activated charcoal or other material suitable for eliminating odours and harmful particles from the air.
It will be understood of course that modifications can be made in the preferred embodiments illustrated and described herein without departing from the scope and purview of the invention.
