Abstract

Abstract The present invention relates to vacuum systems and more particularly, to systems for cleaning up waste materials and/or recovering materials which might otherwise be considered waste, particularly in industrial uses. The instant invention includes a means for creating and applying a vacuum to a localized area, means for collecting materials and a pair of annular rings connected by a spacer means arranged so as to prohibit retained materials from entering the vacuum creation means and means for minimizing the amount of ambient noise disturbance including a sound dampening sleeve member and a helical spring member fitted within said sleeve. Additional embodiments of the present invention include mounting the vacuum means on a frame having articulated wheels thereon and a frame arranged to allow the collection means to be dumped. The present invention may also include means for determining the level of any fluid collected within the collection means which is easily observable to the operator of the instant vacuum cleaner.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 90 words
A vacuum cleaner having; means for creating a vacuum; means for applying the vacuum created to a localized area; means for collecting materials retrieved by the localized application of the vacuum; means for prohibiting said retained materials from entering the means for creating a vacuum, said means including two annular disks connected by spacer means; means for minimizing the amount of ambient noise disturbance resulting from said means for creating a vacuum, said means including a sound dampening sleeve member and a helical spring member fitted within said sleeve member.
Claim 2
Dependent Claim 90 words
A vacuum cleaner having; means for creating a vacuum; means for applying the vacuum created to a localized area; means for collecting materials retrieved by the localized application of the vacuum; means for prohibiting said retained materials from entering the means for creating a vacuum, said means including two annular disks connected by spacer means; means for minimizing the amount of ambient noise disturbance resulting from said means for creating a vacuum, said means including a sound dampening sleeve member and a helical spring member fitted within said sleeve member.
Claim 3
Dependent Claim 22 words
A vacuum cleaner as set forth in claim 1 wherein said means for minimizing the amount of ambient noise disturbance is flexible.
Claim 4
Dependent Claim 41 words
A vacuum cleaner as set forth in claim 1 wherein said means for collecting materials is pivotly mounted to a frame, said frame having articulated wheels connected thereto and said frame is arranged to allow said collection means to be dumped.
Claim 5
Dependent Claim 39 words
A vacuum cleaner as set forth in claim 1 wherein said means for creating a vacuum include two motors mounted to a first wall of a motor housing, said first wall being in fluid connection with a vacuum plenum.
Claim 6
Dependent Claim 36 words
A vacuum cleaner as set forth in claim 1 wherein said collection means also includes means for determining the level of any fluid collected therein which is easily observable to the operator of said vacuum cleaner.
Claim 7
Dependent Claim 63 words
A vacuum cleaner as set forth in claim 1 wherein said means for prohibiting retrieved materials from entering the means for creating the vacuum further includes a porous filter member, said porous filter member being covered by a screen material, said screen material having perforations therein to not impeded the flow of air therethrough when said means for creating said vacuum is actuated.
Claim 8
Dependent Claim 43 words
A vacuum cleaner as set forth in claim 1 wherein said means for collecting retrieved materials includes a means for slidably engaging a forklift in such a way as to permit said collection means to be raised, lowered and transported by a forklift.
