DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0026] The current invention may be classified as a system, method, apparatus and or combinations thereof. The following detailed description does not define any aspect in a particular order of importance but rather attempts to organize the following for convenience only. Furthermore, it is contemplated that the invention may be utilized in other applications other than just concrete joint applications. The used terminology should not be considered limiting. It is further understood and contemplated that the current invention may be used in association with other applications and utilities.

[0027] Referring now to the drawings, wherein like reference numerals designate corresponding structure throughout the views, and referring in particular to FIG. 1 and FIG. 2, reference numeral 10 generally refers to a new and improved construction system, method, apparatus, and or combinations thereof, hereinafter referred to collectively as invention 10, in accordance with the present invention.

[0028] It is contemplated that invention 10 may include a ride-on power trowel body 40 as known in the art as having a skirt 20, a first rotor 30 and a second rotor 35. It is understood that invention 10 contemplates retro fitting existing ride-on power trowels and or manufacturing a device similar to the current ride-on power trowels with the embodiments of the current invention. It is also contemplated that invention 10 may include a kit for converting prior art ride-on power trowel into the current invention.

[0029] First rotor 30 may have arms 50 that rotationally connect to head assemblies 70 such as but not limited to shaft 60. First rotor 30 head assemblies 70 may rotate in direction 80 while first rotor 30 may rotate in the opposite direction 90. Head assemblies 70 may be chain 100 driven around rotatable sprocket 102 that may be fixed to the bottom of skirt 20. It is understood that first rotor 30 direction 80 may be clockwise or counter clockwise and head assembly 70 direction 90 would be opposite. It is also understood that more or less arms 50 are contemplated as well as number of head assemblies 70.

[0030] Second rotor 35 may have arms 55 that rotationally connect to head assemblies 75 such as but not limited to shaft 65. Second rotor 35 head assemblies 75 may rotate in direction 85 while first rotor may rotate in the opposite direction 95. Head assemblies 75 may be chain 105 driven around rotatable sprocket 107 that may be fixed to the bottom of skirt 20. It is understood that second rotor 35 direction 85 may be clockwise or counter clockwise and head assembly 75 direction 95 would be opposite. It is also understood that more or less arms 55 are contemplated as well as number of head assemblies 75.

[0031] It is also understood that first rotor 30 and second rotor 35 may generally rotate in opposite directions. Skirt 20 may be covered with a rubber cowling 110 and a water source 120 may be provided for the grinding and or polishing.

[0032] Head assemblies 70 and 75 may include respectively four disc pads 130 and or 135 that may be diamond tool pads and or other bonded abrasive as known in the art. It is understood that disc pads 130 and or 135 may be more or less than four and may be configured in numerous fashions and may be elongated clip for pads 130. It is also understood that arms 50 and or 55 may be free spring rigid.

[0033] It is therefore contemplated that the current invention may be a planetary grinder and polisher for grinding and polishing cement slabs comprising a ride-on power trowel body with a skirt having a top and a bottom and further having; a first rotor assembly on said bottom of said skirt adapted to rotate in a clockwise direction having at least 3 arms each having a distal end with a rotationally attached head assembly adapted to spin counterclockwise and wherein said head assembly has at least three disc pads adapted to grind and polish cement; a first rotatable sprocket fixed on said bottom of said skirt; a first chain adapted to rotate said at least three assembly of said first rotor assembly in a counterclockwise direction and in communication with said first rotatable sprocket; a second rotor assembly on said bottom of said skirt adapted to rotate in a counter clockwise direction having at least 3 arms each having a distal end with a rotationally attached head assembly adapted to spin clockwise and wherein said head assembly having at least three disc pads adapted to grind and polish cement; a second rotatable sprocket fixed on said bottom of said skirt; and a second chain adapted to rotate said at least three assembly of said first rotor assembly in a clockwise direction and in communication with said first rotatable sprocket.

[0034] Changes may be made in the combinations, operations, and arrangements of the various parts and elements described herein without departing from the spirit and scope of the invention. Furthermore, names, titles, headings and general division of the aforementioned are provided for convenience and should, therefore, not be considered limiting.
