Abstract
Abstract A blower apparatus for a plant cutter including a hollow member affixed to conduct exhaust gases from the cutter. The hollow member conducts exhaust gases from the plant cutter to a connected rotatable hollow member and through a terminal opening in the rotatable hollow member. The rotatable hollow member adjusts the distance between the terminal opening and the cut vegetable resulting from the cutting mechanism of the lawn cutter.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
188 words
A blower apparatus for an exhaust gas producing plant cutter comprising: a. hollow member affixed to conduit exhaust gases from the plant cutter; b. rotatable hollow member communicating with said hollow member said rotatable hollow member having an end portion culminating in a terminal opening behind the cutting mechanism of the plant cutter, the rotation of said rotatable hollow member adjusting the distance between said terminal opening and the cut vegetation resulting from the cutting mechanism of the plant cutter, such that exhaust gases from the cutter pass through said hollow member, rotatable hollow member, and terminal opening, said distance adjustment varying the ability of the exhaust gases to blow the plant cuttings; c. adjustable support means for positioning said rotatable hollow member against the forces of gravity and reaction force exerted by the exhaust gases, said adjustable support means comprising a slotted bracket affixed to a portion of the plant cutter; an elongated member fitting within said slot and movable along the length of said slot; means for holding said elongated member to said rotatable member and means for fixing said elongated member to said slotted bracket.
Claim 2
Dependent Claim
188 words
A blower apparatus for an exhaust gas producing plant cutter comprising: a. hollow member affixed to conduit exhaust gases from the plant cutter; b. rotatable hollow member communicating with said hollow member said rotatable hollow member having an end portion culminating in a terminal opening behind the cutting mechanism of the plant cutter, the rotation of said rotatable hollow member adjusting the distance between said terminal opening and the cut vegetation resulting from the cutting mechanism of the plant cutter, such that exhaust gases from the cutter pass through said hollow member, rotatable hollow member, and terminal opening, said distance adjustment varying the ability of the exhaust gases to blow the plant cuttings; c. adjustable support means for positioning said rotatable hollow member against the forces of gravity and reaction force exerted by the exhaust gases, said adjustable support means comprising a slotted bracket affixed to a portion of the plant cutter; an elongated member fitting within said slot and movable along the length of said slot; means for holding said elongated member to said rotatable member and means for fixing said elongated member to said slotted bracket.
Claim 3
Dependent Claim
39 words
The apparatus of claim 1 which additionally comprises muffling means for reducing the noise of the exhaust gases of the lawn cutter; said muffling means at least partially disposed about the exterior of a portion of said hollow member.
Claim 4
Dependent Claim
25 words
The apparatus of claim 1 in which said end portion of said rotatable member includes a converging nozzle, said terminal opening being the nozzle opening.
Claim 5
Dependent Claim
39 words
The apparatus of claim 3 which additionally comprises muffling means for reducing the noise of the exhaust gases of the lawn cutter; said muffling means at least partially disposed about the exterior of a portion of said hollow member.
Claim 6
Dependent Claim
44 words
The apparatus of claim 3 in which said nozzle has an end portion of two pairs of opposed sides, each pair of said sides lying in intersecting planes with respect to each other, sure that each pair of sides converges toward said terminal opening.
Claim 7
Dependent Claim
88 words
The apparatus of claim 3 in which said means for fixing said elongated member to said slotted bracket includes a pair of internally threaded members threadingly engaging a first threaded portion of said elongated member, said pair of threaded members placed on opposite sides of said slotted bracket; and said means for holding said elongated member to said rotatable hollow member comprises a third internally threaded member threadingly engaging a second threaded portion of said elongated member, said third internally threaded member affixed to said rotatable hollow member.
Claim 8
Dependent Claim
88 words
The apparatus of claim 1 in which said means for fixing said elongated member to said slotted bracket includes a pair of internally threaded members threadingly engaging a first threaded portion of said elongated member, said pair of threaded members placed on opposite sides of said slotted bracket; and said means for holding said elongated member to said rotatable hollow member comprises a third internally threaded member threadingly engaging a second threaded portion of said elongated member, said third internally threaded member affixed to said rotatable hollow member.
