The drawing represents a tool embodying the invention.
Figure 1 is a side view if the plane. Fig. 2 is a top view
thereof. Fig. 3 is a bottom view. Fig. 4 is a cross-section
on the line x x. a denotes the bottom plate
if the plane; b, an upright, extending from one edge
of said plate; c, the throat through which the cutters
or plane-bits extend and the chips escape. d e denote
the two cutters, set at an angle to both plates a b,
and at a right angle to each other, the cutter d resting
upon a bed-piece, f, and its cutting-edge extending
through the throat c, and so as to be in a horizontal
plane just beyond the bottom face of the plate a, and
the cutter e sitting edgewise on top of the cutter
d, and with its inner face against a bed-piece, g,
the cutter e also extending through the throat c,
but its cutting edge being vertical and standing just beyond
the outer face of the upright b, the two cutting-edges
standing, therefore, at a right angle and being in effect
one cutting-edge, bent so as to be one vertical and one part
horizontal. The two cutters are held by an angular clamp,
h, which is pressed down against the cutters by a screw,
i, passing through a bar, k, and the clamp h
has a shoulder, l, extending over the edge of the cutter
e is pressed against the cutter d, bringing
their cutting-edges together and firmly securing them in position.
On the outer face of the upright b is fastened a gage,
m, which, by screws n and slots o is
made adjustable, and this gage determines the depth of cut
of the two cutters.
As the tool is used, as before described the edge d
cuts across the grain, and the edge e with the grain,
and b the action of the two cutters together the work
is very rapidly effected, and the block uniformly surfaced
or resurfaced.
I claim-
|
1.
|
The surfacing-plane, formed with the two cutters, d
and e, having their edges in line and standing
one in horizontal and the other in vertical position,
combined with the gage m, on the vertical face
of the plane, substantially as described. |
|
|
|
|
2.
|
In combination with the two cutters, the clamp h,
for holding the cutters, substantially as shown and described. |
|
|

3.
|
The clamp, formed with the shoulder l, for pressing
the cutter e down to the cutter d, substantially
as shown and described. |
