To all whom it may concern:
Be it known that I, SAMUEL FRISBIE, a citizen of the United
States, residing at Unionville, in the county of Hartford and
State of Connecticut, have invented certain new and useful Improvements
in Bench-Planes, of which the following is a specification.
My invention relates to improvements in bench-planes; and the
objects of my improvements are simplicity in construction and
efficiency in operation.
In the accompanying drawings, Figure 1 is a central longitudinal
section, partly in elevation, of my plane. Fig. 2 is a sectional
view of the same on the line x x of Fig. 1, looking
squarely upon the face of the movable bed. Fig. 3 is a central
longitudinal section, partly in elevation, of my plane in its
preferred form; and Fig. 4 is a transverse section of the stock
on line y y of Fig. 3, together with a rear elevation
of the remaining parts, the cutting-bit and holding-cap being
removed.
A designates the stock, of any ordinary form in its general
features, and provided with a short section of a frog or seat
5 for the lower end of the cutting-bit 6, said frog-section
having on its rear under side a perforation in which the tenon
or projection 7 of the moveable cutter-bed 8 is loosely fitted,
so that said bed may move longitudinally with the cutting-bit,
and also rock laterally at its upper end, the tenon 7 serving
as a fulcrum on which it rocks. The rear and upper end of this
moveable bed rests upon a stud 9, and is held in place thereon
by means of the screw 10, which passes through a slot in said
bed, so as to permit a certain degree of longitudinal and transverse
movement of the bed. This bed is so mounted upon the end of
the stud 9 that its upper face is substantially a continuation
of the sloping face of the frog-section 5. The holding-cap 11,
of ordinary construction, is held in place by the screw 12 for
clamping the cutting-bit 6 firmly upon the movable bed 8 substantially
as such holding-cap and screw have heretofore held the bit upon
a stationary bed. The longitudinal adjustment of the cutting-bit
is effected by means of the adjusting-screw 13, which carries
the movable bed up and down and the cutting-bit with it. |
