Abstract
Abstract This invention relates to a collecting assembly for grass cuttings, clippings, various debris, etc. and it is designed primarily to be used in combination with a cutting machine. The cutting machine may be a riding mower or a push or walk behind type. A storage means including a removable container element for receiving the debris is arranged in fluid communication with a negative pressure source which may be a vacuum-type pump or impeller element disposed in fluid communication with the storage means to create a negative pressure therein. Conduit means interconnects the cutting deck or cutting area of the cutting machine with the storage means wherein the cutting area, conduit means, storage means and negative pressure source means are all arranged in fluid communication so as to substantially define a negative fluid flow pressure throughout the system. Fluid flow is accordingly directed from the cutting area along with the debris entrained in said fluid flow into the storage area. Filter means is positioned in path interruptive relation between the interior of the storage means and the negative pressure source so as to allow filtered or debris free air from leaving the storage means and exiting to atmosphere through direction of the negative pressure source.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
215 words
A cutting machine with a cutting means and a collecting assembly for the cut debris, said assembly comprising: a positive source of fluid flow contiguous to the cutting means and in fluid communication therewith, debris storage means, a first conduit means interconnected between the cutting means and said debris storage means to establish fluid communication therebetween, said positive source of fluid flow comprising impeller means rotatably mounted in the cutting means of the cutting machine, whereby debris is entrained in the established fluid flow and directed through said first conduit, a negative pressure source means independent of said positive source of fluid flow and disposed in fluid communication with said debris storage means and said cutting means said first conduit means, said negative pressure source means comprising a second conduit means interconnecting in fluid communication said storage means and said negative pressure source means, whereby enhanced fluid flow is established from said cutting area through said storage means, said debris storage means comprising container means connected to said cutting machine and being disposed in fluid communication with both said positive source of fluid flow and said negative fluid pressure, and said container means adapted to receive a disposable container element in which debris is removable from said container means as a desired quantity is collected.
Claim 2
Dependent Claim
215 words
A cutting machine with a cutting means and a collecting assembly for the cut debris, said assembly comprising: a positive source of fluid flow contiguous to the cutting means and in fluid communication therewith, debris storage means, a first conduit means interconnected between the cutting means and said debris storage means to establish fluid communication therebetween, said positive source of fluid flow comprising impeller means rotatably mounted in the cutting means of the cutting machine, whereby debris is entrained in the established fluid flow and directed through said first conduit, a negative pressure source means independent of said positive source of fluid flow and disposed in fluid communication with said debris storage means and said cutting means said first conduit means, said negative pressure source means comprising a second conduit means interconnecting in fluid communication said storage means and said negative pressure source means, whereby enhanced fluid flow is established from said cutting area through said storage means, said debris storage means comprising container means connected to said cutting machine and being disposed in fluid communication with both said positive source of fluid flow and said negative fluid pressure, and said container means adapted to receive a disposable container element in which debris is removable from said container means as a desired quantity is collected.
Claim 3
Dependent Claim
50 words
The cutting machine of claim 1 wherein the cutting means comprises a driven shaft for rotating a cutting blade; and said positive source of fluid flow comprising an auxiliary impeller mounted on said shaft for rotation therewith for creating an air flow within the cutting area through said first conduit.
Claim 4
Dependent Claim
38 words
The cutting machine of claim 1 wherein said container means is movable connected to the cutting machine and positionable for access to the interior of said storage means whereby contents of said storage means may be removed therefrom.
Claim 5
Dependent Claim
36 words
The cutting machine of claim 3 wherein said first conduit means is adjutably interconnected and positioned between said storage means and said, whereby relative displacement between said storage means and the cutting machine is compensated for.
Claim 6
Dependent Claim
45 words
The cutting machine of claim 1 wherein said storage means comprises head means mounted thereon, said first conduit means and said negative pressure source means are each connected to said head in fluid communicating relation to one another and the interior of said storage means.
Claim 7
Dependent Claim
32 words
The cutting machine of claim 5 wherein said head means is movably attached to at least said first conduit means for relative movement therebetween during operation or movement of the cutting machine.
Claim 8
Dependent Claim
46 words
The cutting machine of claim 1 further comprising filter means connected to said storage means and disposed in the path of fluid flow between said negative pressure source means and said storage means, whereby debris is filtered from fluid flow to said negative pressure source means.
Claim 9
Dependent Claim
32 words
The cutting machine of claim 7 further comprising screen means dimensioned in predetermined relation relative to the collected debris directed to said storage means to prevent passage thereof through said second conduit.
Claim 10
Dependent Claim
45 words
The cutting machine of claim 7 further comprising deflector means in interruptive relation relative to the flow of fluid and entrained debris, said deflecting means further disposed relative to the remainder of the storage means as to direct debris impinging thereon into said storage means.
