Abstract

Abstract A disintegrator is composed of (1) a mulch plate with one or more raised diffusers composed of evenly spaced bars rising from the plate with spaces between them, and (2) one or more mulch bars each composed of a bar with teeth projecting from one surface spaced to pass through the spaces between the bars of the diffusers. The mulch bar is positioned to rotate with respect to a fixed location on the mulch plate so that the teeth will pass through the spaces between the bars of the one or more diffusers. The plate may be perforated or imperforate. In the preferred disintegrator, one or more narrow portions of the mulch plate in areas extending substantially radially from said fixed location are fabricated into diffusers. The bars and spaces of each diffuser are arranged substantially circumferentially of said fixed location so that the teeth of the mulch bar pass through them as it is rotated. The spaces between the bars of the diffuser extend through the plate, either as one long opening under the entire diffuser (which is the case when the diffuser is fabricated separately from the plate) or as separate openings (which may be the case when the diffuser is formed from the plate). The disintegrator is a multi-purpose disintegrator and is well suited for use in an implement such as an outdoor-area cleaner provided with a fan which sucks or blows leaves, twigs, etc. from an area such as a lawn, drive, parking area, etc. against the front face of the disintegrator where the teeth of the one or more mulch bars push them to, and through the spaces in a diffuser where they are disintegrated and go through the opening in the plate without further treatment. The implement is advantageously provided with a bag which catches the disintegrated material. The implement may be operated in any suitable manner. The mulch plate for a disintegrator used for this purpose is generally perforated so that the blower which sucks or blows the leaves through it can blow or suck a relatively uniform quantity of air through the plate at all times. There are various applications for the disintegrator.

Claims Analysis

Total Claims: 12
Claim 1
Independent Claim 14 words
The disintegrator of claim 1 in which the ribs are integral with the plate.
Claim 2
Dependent Claim 17 words
The disintegrator of claim 1 in which the ribs are in an element fastened to the plate.
Claim 3
Dependent Claim 18 words
The disintegrator of claim 1 in which the teeth are a sinuous steel strip with a cutting edge.
Claim 4
Dependent Claim 51 words
An outdoor-area cleaner which may be moved over a surface, a disintegrator of claim 1 located therein in a housing which has an opening at the surface, a blower for sucking leaves, twigs, etc. from the surface and sucking or blowing them through the disintegrator, and an exhaust from the blower.
Claim 5
Dependent Claim 37 words
The cleaner of claim 5 in which the plate is perforated with additional openings smaller than the aforesaid openings to provide for the passage of a larger volume of air than is accommodated by the aforesaid openings.
Claim 6
Dependent Claim 20 words
The cleaner of claim 6 in which the blower is situated to suck the leaves, twigs, etc. through the disintegrator.
Claim 7
Dependent Claim 17 words
The cleaner of claim 7 which includes a bag fOr collecting solid matter at the blower exhaust.
Claim 8
Dependent Claim 93 words
The process of disintegrating material which comprises supplying the material to a plate having ribs raised from one surface thereof with spaces between the ribs arranged circumferentially with respect to a fixed location on the plate, there being material-discharge openings between said ribs rotating a bar about said location with a series of teeth thereon spaced to pass between said ribs, and thereby moving constantly renewed portions of the material over the plate and forcing them between the ribs and thereby disintegrating the material and passing it through said openings in the plate.
Claim 9
Dependent Claim 46 words
The process of claim 9 in which the material is sucked against the plate by a blower and there are small openings in the plate to allow passage of sufficient air therethrough to provide for passage of a substantially constant volume of air through the plate.
Claim 10
Dependent Claim 16 words
The process of claim 9 in which the material after passing through the openings is bagged.
Claim 11
Dependent Claim 20 words
The process of claim 10 in which leaves, twigs, etc. are sucked from a relatively flat surface through the disintegrator.
Claim 12
Dependent Claim 23 words
The disintegrator of claim 1 in which openings smaller than said one or more openings are distributed throughout the area of the plate.
