"IMPROVEMENTS IN MACHINES
FOR MOULDING HEEL COUNTERS OR STIFFENERS FOR BOOTS AND SHOES, AND IN
THE MOULDS AND DIES USED THEREFOR." A communication from abroad by Michael
Hynes and Napoléon Joseph Coté, both of the City of Montreal, Canada.
The apparatus embodies the following features:
An endless feeding apron carrying the pack of counter blanks; a slide to separate
and convey a single blank to the feed and corrugating rollers; feed and corrugating
roller's to corrugate the edge of the blank and means to bring it to the mouth of
the female die in which the counter is formed; a stop or gauge and guide plates to
adjust its position; a female die or mould; male die or former, to shape the counter ;
and expellers to eject the formed counter from the mould and remove it from the
male die.
The particular features of the construction of the several parts and their
operation may be briefly described as follows:-
A. pack of counter blanks of the usual material is laid chords downwards on the
endless apron
which is carried on rollers and moved by any suitable means; this
brings the pack to a point where the slide which (receiving motion from a cam
wheel and through links, adjustable to suit varying thicknesses of counters)
separates by a projecting stud oue blank from the pack, this blank advancing with
the slide into the bite of the feed and corrugating rollers to which motion is
imparted from a counter shaft driven by the main shaft or in any other suitable
way.
The chord edge of the blank having been corrugated the desired distance the
blank is further advanced to a position in front of the mouth of the female die by
a stud or other suitable means and is brought up against a gauge carried between
two guide plates so constructed that while holding the blank properly in place they
will allow of its easy escape therefrom when pushed by the male die into the
mould to form the counter and also enable the ends to be turned down without
obstruction.

page_text: The female die is formed in two parts resting against elastic bearings carried
in metal plates and having in rear-adjustable wedges.
These parts are each formed with a shoulder on the bottom so as to bend up the
-bottom lip of the counter and form the "upturn" and each has also at its mouth a
recess tapering inwards, and is further constructed as follows :-
For some little distance back of the mouth or entrance the sides (curved.
vertically) are parallel to each other longitudinally and have cut in theu, in the
rear of such straight moulding surfaces, openings in which are placed movable-side
sections adapted to be rotated around independent axes perpendicular to the plane
of movement of the forming die and having their inner surfaces curved to fit the
male die, their operation being by the movement of the male die, to curve inward
around it the forward ends of the counter, and cause them to assume the exact
shape of the last.
There is also in combination with these wings, or side pieces, or sections, hinged,
pivotted, or revolving at points between their ends, a heel block having its inner
surface concaved to form a continuation of the sides and the whole corresponding to
the contour of the male die or former, to which reciprocating motion is imparted.
by any suitable means from the main shaft.
Two expellers suitably provided with springs operate respectively to eject the
counter from the mould and force it off the male die.
