Appeal No. 2006-1915
Application No. 10/056,312
THE INVENTION
The appellants have invented a miter saw having greater cutting capacity. In
essence, the appellants’ invention displaces the motor, and motor housing, from a
saw blade axis to a position which permits a greater range of mitering without
interference with the workpiece. The appellants’ invention accomplishes this in
part by providing a first gear G on the saw blade arbor A, an intermediate gear G2
meshing with the first gear, and a second gear G3 driven by a motor M and
meshing with the intermediate gear. The motor drives the second gear via a belt B,
rather than directly, to achieve additional displacement of the motor. Claim 1, the
only claim pending in this application, reads as follows:
1. A miter saw comprising:
a base assembly;
a rotatable table rotatably connected to the base
assembly and having a plane;
a saw assembly including a motor, and a blade
disposed on an arbor, the arbor having a first portion
carrying the blade, a second portion disposed away from
the blade, and a first gear disposed on the second portion,
an intermediate gear meshing with the first gear, and a
second gear driven by the motor and meshing with the
intermediate gear, wherein the intermediate gear is
always meshing with the first and second gears, the
second gear being driven by the motor via a belt; and
a pivot arm pivotally attached to the table and
supporting the saw assembly, the pivot arm and saw
assembly being pivotable about a horizontal bevel axis
from a first position where the blade is substantially
perpendicular to the table to a second position where the
blade is disposed at an angle relative to the table, the
