First Claim
Patent Images
1. A router comprising:
- (a) a base assembly including an annular base member supporting an upright cylindrical base member;
(b) a cylindrical motor housing telescopingly and slidably received within said cylindrical base member, said motor housing having a plurality of vertically aligned, spaced first formations;
(c) a vertical adjustment mechanism supported by said base assembly, said adjustment mechanism including a lever and an adjustment means for moving the lever vertically with respect to the base assembly, said lever having a second formation and being mounted for movement back and forth between (i) a first position wherein said second formation is in engagement with a selected one of said first formations to prevent vertical sliding movement of the motor housing relative to the lever and (ii) a second position wherein said second formation is disengaged from said first formations thereby permitting vertical sliding movement of said motor housing relative to said lever.

Abstract
The fixed-base router has an annular base member supporting a cylindrical base member. A cylindrical motor housing is telescopingly received within the cylindrical base member; the motor housing includes three vertically aligned notches. A vertically disposed rod is rotatably mounted by the cylindrical base member. The rod includes an external threaded area in threading engagement with a threaded bore in a lever. The lever includes a latch for engagement with a selected one of the notches for coarse vertical adjustment. Fine vertical adjustment is obtained by rotating the rod with the latch in engagement with one of the notches.

8. A router comprising:
-
(a) a base assembly including an annular base member supporting an upright cylindrical base member; (b) a cylindrical motor housing telescopingly and slidably received within said cylindrical base member, said motor housing having a plurality of vertically aligned, spaced first formations; (c) a vertical adjustment mechanism supported by said base assembly, said adjustment mechanism including a vertically disposed rod mounted for movement about its longitudinal central axis, said rod including an external threaded area, said adjustment means also including a lever having a threaded bore in threading engagement with the threaded area of said rod, whereby rotation of said rod serves to move said lever vertically, said lever having a second formation and being movable back and forth between (i) a first position wherein said second formation is in engagement with a selected one of said first formations to prevent vertical sliding movement of the motor housing relative to the lever and (ii) a second position wherein said second formation is disengaged from said first formations thereby permitting vertical sliding movement of said motor housing relative to said lever. - View Dependent Claims (9, 10, 11)
