Abstract
Abstract An adapter system and attachments therefor which utilizes the structural and drive features of powered lawn mowers inclusive of the cutter blade-fan to provide additional power rake, brush, edger and nonscalping features. A drive connection is provided to power a horizontally disposed shaft upon which flails and similar edger or lawn dressing tools may be positioned for contact with a lawn or turf surface. Flexible tines or flails of a power-rake attachment are held in operative position by a plurality of intermeshing disc supports. A combination cutter blade-fan is used in alternate positions, and a mounting component therefor provides a nonscalping feature.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
244 words
In a lawn mower normally having a housing constituting a frame structure providing a discharge opening for grass cuttings, support wheels on said frame for moving the unit along a turf surface, a drive motor and drive, a blade-fan operatively connected to said drive, an attachment for use with and disposed beneath said blade-fan comprising engaging means for attachment to the blade-fan drive of said lawn mower, reduction means connected to said engaging means and providing an output drive at reduced speed, a driven shaft engaged to said output drive for rotation about a horizontal axis in position closely adjacent to the turf to be conditioned, resilient impact rotating members for disposition in side by side relation, a plurality of separate drive connector components disposed cooperatively in interconnected side by side relation on said driven shaft and operative with said impact rotating members for supporting said impact rotating members and interconnecting said impact rotating members to the driven shaft whereby the members are rotated for repeated contact with the turf, and means provided by said drive connectors and cooperative with respect to the resilience of said impact rotating members for allowing relative freedom of movement between said impact rotating members and the driven shaft to prevent damage to said elements when obstructions on the turf surface are contacted by said rotating members, said blade-fan being operative to move and discharge materials loosened by the impact rotating members through the discharge opening of said housing-frame.
Claim 2
Dependent Claim
244 words
In a lawn mower normally having a housing constituting a frame structure providing a discharge opening for grass cuttings, support wheels on said frame for moving the unit along a turf surface, a drive motor and drive, a blade-fan operatively connected to said drive, an attachment for use with and disposed beneath said blade-fan comprising engaging means for attachment to the blade-fan drive of said lawn mower, reduction means connected to said engaging means and providing an output drive at reduced speed, a driven shaft engaged to said output drive for rotation about a horizontal axis in position closely adjacent to the turf to be conditioned, resilient impact rotating members for disposition in side by side relation, a plurality of separate drive connector components disposed cooperatively in interconnected side by side relation on said driven shaft and operative with said impact rotating members for supporting said impact rotating members and interconnecting said impact rotating members to the driven shaft whereby the members are rotated for repeated contact with the turf, and means provided by said drive connectors and cooperative with respect to the resilience of said impact rotating members for allowing relative freedom of movement between said impact rotating members and the driven shaft to prevent damage to said elements when obstructions on the turf surface are contacted by said rotating members, said blade-fan being operative to move and discharge materials loosened by the impact rotating members through the discharge opening of said housing-frame.
Claim 3
Dependent Claim
16 words
Structure as set forth in claim 1 wherein a plurality of adjacent separate parts are identical.
Claim 4
Dependent Claim
33 words
Structure as set forth in claim 1 wherein said separate parts each provide at least one protuberance and one receptacle with the protuberances and receptacles of separate parts being adapted for mating contact.
Claim 5
Dependent Claim
21 words
Structure as set forth in claim 3 wherein said mating protuberance and receptacle combination provides support for said impact rotating members.
Claim 6
Dependent Claim
30 words
Structure as set forth in claim 1 wherein said separate parts in their assembled relationship provide a recess facilitating the desired relative freedom of motion for said impact rotating members.
Claim 7
Dependent Claim
71 words
Structure as set forth in claim 1 wherein said engaging means rotates with said drive motor and is inclusive of a fastener extending downwardly beneath said attachment and in position for contact with the ground surface and/or obstructions thereon and further including a curved or rounded end whereby said attachment and the rake elements thereof will be raised to prevent damage thereto and to the turf when raised obstructions are encountered.
Claim 8
Dependent Claim
25 words
Structure as set forth in claim 2 wherein the adjacent separate parts are of substantially disk shape extending outwardly from a centrally disposed driven shaft.
Claim 9
Dependent Claim
47 words
Structure as set forth in claim 7 wherein a plurality of protuberances and receptacles are provided on said disk parts with the protuberances and receptacles of the separate disk parts being adapted for mating contact and with the impact rotating members being mounted on said mated protuberances.
Claim 10
Dependent Claim
28 words
Structure as set forth in claim 8 wherein the protuberances for said disk parts are disposed on one side thereof and the receptacles on an opposite side thereof.
Claim 11
Dependent Claim
18 words
Structure as set forth in claim 8 wherein said impact rotating members are of a reverse curve shape.
Claim 12
Dependent Claim
43 words
Structure as set forth in claim 10 wherein said separate disk parts in their assembled relationship provide a recess cooperative with respect to the resilience of said impact rotating members to provide the desired relative freedom of motion for said impact rotating members.
Claim 13
Dependent Claim
182 words
In a lawn mower normally having a housing constituting a frame structure providing a discharge opening for grass cuttings, support wheels on said frame for moving the unit along a turf surface, a drive motor, a vertically disposed drive connected to said drive motor, a blade-fan rotating in a horizontal plane and operatively connected to said drive for cutting grass and delivering the cut grass through said discharge opening, an attachment for use with said blade-fan comprising engaging means for interconnection to the blade-fan drive of said lawn mower, a driven shaft mounted on said housing-frame for rotation about a horizontal axis, power transmission means interconnecting said engaging means and said driven shaft for rotating said shaft, impact rotating members for disposition in side by side relation on said horizontally disposed driven shaft, drive connector components for interconnecting said impact rotating members to the driven shaft whereby the members are rotated for repeated contact with the turf for power-rake purposes, and an edger blade rotated by said horizontal driven shaft and disposed for contact with said turf surface for edge trimming operations.
