I, CLAUDIUS ERSKINE GOODMAN, of No. 25, Euston Road, in the County of
Middlesex, do hereby declare the nature of the said Invention for "IMPROVE-
MENTS IN MACHINERY EMPLOYED IN THE MANUFACTURE OF BOOTS AND SHOES," to be
as follows:-
This Invention has for its object improvements in machinery employed in
the manufacture of boots and shoes. For these purposes in order to form
and finish the edges of the soles and heels of boots and shoes, a clamping
apparatus is employed and mounted on a revolving chuck, such clamping
apparatus shielding or protecting the upper of a boot or shoe whilst it at the
same time acts as a template in controlling the action of the cutter in making
its cut on the edge of the sole of the boot or shoe held therein. The clamping
apparatus is made by preference in two parts or halves longitudinally, though
the number of its parts might if desired be varied. The clamping apparatus.
is formed to receive the "upper" in such a manner that the edges of the
clamping apparatus pass in between the sole and the upper where the two
are connected together. The clamping apparatus is received into and revolves
with a chuck which is caused to rotate, but the chuck is also arranged to
slide on the end of its shaft or axis, so that notwithstanding the irregularity
in the form of the edge of a sole of a boot or shoe, such edge is by the
rotation and sliding of the chuck, together with its having the capability of

page_text: being moved to and from a stationary or fixed cutter, constantly presented to
the cutter so as to have a shaving cut from the edge of the sole, and by
reason of the clamping apparatus acting as a template determining the position
of every part of the edge of the sole when opposite the cutter the proper
form of the sole and heel will be produced, whatever be the form in which
the sole or heel are when introduced into the machine; but it is desirable
that the sole and heel should be roughly cut to the desired shape before intro-
ducing a boot or shoe into the machine.
The chuck employed by preference is of an oblong form with semicircular
ends, and is provided with a toothed rack work all round, into which the
teeth of a pinion gear. This pinion is carried by a second shaft or axis
which receiving a rotary motion from any suitable power gives metion to
the chuck and its shaft or axis, but other forms of eccentric chucks may be
used.
The frame which carries. the two shafts or axes before mentioned is
mounted on another shaft or axis, so that the frame together with the chuck
and the contained boot or shoe can by means of cam surfaces be caused
to assume various positions in order that the varying curves of the sole may
be presented at a suitable angle to the cutting instrument The foregoing
apparatus is mounted on a sliding frame driven by a suitable cam, by which
means the bottom of the sole is during its rotation maintained at the same
distance from the rest..
The cutter or knife by which the cutting or paring of the edge of the sole
and heel is performed is fixed or held on a stationary rest, and has a cutting
edge suitable for cutting shavings off the edge of the sole.
