Improvements in Machines for Forming or Making Irons for the
Soles and Heels of Clogs and Heels of Boots and Shoes.
We, THE PARKIN PATENT NAIL COMPANY LIMITED, and GEORGE HENRY
PARKIN of the said Company, of Chapel Hill Mills, Huddersfield, Yorkshire, Nail
Manufacturers, do hereby declare the nature of this invention to be as follows:-
_
This invention has reference to machines for forming, shaping, or making clog
irons and heel pieces and irons for boot or shoe heels, and consists of means for
cutting off the requisite length of iron and forming or bending it to the required
shape in one machine and at one operation.
In carrying out our invention we attach a moveable cutter to a suitable plate
adapted to slide in-ways in the headstock of the machine and actuated by cam or
tappet on a cross shaft rotated by crank and connecting rod from the main driving
shaft. The iron from which the articles above named are to be cut and bent, is fed
in at one side of the machine and engages with a guage piece or adjustable stop set
to the required distance to give the proper length of iron to form the heel or sole
piece, this length being severed from the bar of iron by the cutter and held in
position for the shaper.
The shaper for shaping clog heels may be fixed to the shaping bar or sliding bed,
by which it is reciprocated backwards and forwards and is provided with a groove
or recess at the end and sides, or is protected at top and bottom by plates. The
sliding bed or shaping bar is actuated from the main shaft or other suitable moving
part of the machine and is timed to advance as the cutter severs the iron so that as
said cutter recedes or moves away again, the shaper engages the severed length
of iron which enters the groove or recess at the end, and is forced by said bar
or shaper past two or more pulleys or bowls mounted on studs on each side of
the track of the shaper, in doing which, the iron is bent round the shaper and the
required shape thus given to it. At or near the end of the forward stroke of the
shaper the extremities of the heel piece are engaged by a suitable hinged finger or
fingers or clearing blades, which, as the shaper commences its return stroke, remove
the heel pieces therefrom and allows it to fall onto the floor or into a receptacle, the
said fingers or clearers being drawn into their normal positions by spring or springs.
One of the bowls above referred to is adjustable to or from the opposite bowl so as
to adapt the machine to different sizes of heels.
The shaper for shaping clog irons and heels for boots and shoes must be
removable out of the groove or recess, to enable the iron after it is bent around
said shaper to be withdrawn, the extremities of said pieces lying nearer to each
other than the mid or central portions, and therefore not permitting them to be
drawn over the shaper as in the case of the clog heels.
The shaper is therefore carried on the end of a spindle passing up through a boss
or collar in the sliding or shaping bar and adapted to slide freely therein when
actuated by a wedge shaped or inclined surface engaging a friction pulley on the
end of said spindle.
The shaper is thus slided into position in the recess or groove as the bar
advances to the severed iron, and after the iron has been bent as previously
described, the bowls or pulleys are caused by suitably arranged wedges, inclined
surfaces, cams, or tappets, operated by or from the main driving shaft, to advance
towards each other to bend or force the extremities of the iron against the reduced

page_text: rear portion of the shaper to complete the formation of the iron, whereupon the
shaper is lowered out of the said recess and therefore enables the bent heel or clog
sole iron to be removed by the "knockers off" or clearing blades, as the sliding bar
returns ready for the next stroke.

Improvements in Machines for Forming or Making Irons for the
Soles and Heels of Clogs and Heels of Boots and Shoes.
We, THE PARKIN PATENT NAIL COMPANY, LIMITED, and GEORGE
HENRY PARKIN, of the said Company, of Chapel Hill Mills, Huddersfield,
Yorkshire, Nail Manufacturers, do hereby declare the nature of this invention
and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement :—
This invention has reference to machines for forming shaping or making clog
irons and heel pieces for boots and shoes and consists of means for cutting off the
requisite length of iron and forming or bending it to the desired shape in one
machine and at one operation.
In order that our invention may be fully understood we hereinafter make
reference to the accompanying drawings illustrative thereof, wherein
Fig. 1 is side elevation of our improved machine for forming irons for clogs and
for heels of boots and shoes, a portion of the rear frame being broken off to shew
some of the parts more clearly,
Fig. 2 is end elevation and Fig. 3 plan of a part of same.
Figs. 4 and 5 are details of parts to be employed in forming irons for boot and
shoe heels.
Figs. 6 and 7 are details hereafter referred to.
1 represents the main driving shaft of the machine on which are mounted fast
and loose pulleys (not shewn) motion being communicated to said shaft by strap
from an overhead shaft or other suitable source of motion. Fast on shaft 1 is a
pinion 2 gearing with a spurr wheel 3 on shaft 4 through which rotary motion is
transmitted to said shaft and by means of crank arms 5 gives a reciprocatory or
backward and forward motion to the sliding bed 6 supported between guides 7 and 8
on each side of the frame 9. To the front end of the sliding bed is bolted a
plate 10 provided with slots as indicated at 11 in Fig. 3 to permit of lateral
adjustment of said plate to suit the size of shaper 12 employed which is secured
thereto as shewn, and preferably consists of three pieces fastened together by
screws 13 so as to be detachable from each other to enable the central part to be
changed; or the said shaper may be removed and a larger or smaller one substituted
therefor. The top and bottom portions of the shaper 12 project a little distance
beyond the edges of the central portion and form a groove or recess 14 at the
end and sides equal in depth to the width of the iron 15 to be bent or formed
thereby.
The iron 15 is fed to the machine through the guide eye 16, and engages with the
adjustable gauge or stop piece 17 as shewn clearly at Fig. 3, which determines the
length to be cut off, the said iron resting upon the bottom stationary cutter 18,
secured by set screws in the part 19 of the frame and adjustable therein, and being
severed by the descent of the top cutter 20 secured to the frame 21 adapted to
slide vertically in ways in the headstock 22 of the machine.
A vertical reciprocatory motion is imparted to said frame by pin 23 fixed
eccentrically on the plate or disc 24 mounted on shaft 25 which receives rotary
motion from the shaft 4 by means of cranks 26 and connecting rod 27. When

page_text: the cutter 20 descends and severs the iron it forces it down onto rests 28 and 29
which support each end of the severed length and hold it in position for the
shaper 12 which is timed to advance as the cutter recedes or rises clear and to
engage the said iron which enters the groove or recess 14 and is forced by said
shaper past the two bowls 30 and 31 mounted on studs in the bars 32 and 33 on
each side of the track of the shaper, said bowls bending the iron around the
central or mid portion of the shaper and thus giving the required shape or formation
thereto. The bowls are grooved as shewn to correspond with the bevil or outer
section of the iron. The bent clog iron is carried by the shaper beyond the fingers
or clearing blades 34 pivoted at 35 in the bars 32, 33, the spiral springs 36.
allowing for this, but immediately the said blades are released they are drawn back
to their normal positions by the before mentioned springs and engage the extremities
of the bent clog iron on the return stroke of the shaper from which the iron is.
thereby detached as shewn in dotted lines in Fig. 3 and is allowed to fall into the
shoot 37 which conveys it into a receptacle or onto the floor. The aforesaid
operations are repeated at every revolution of the shaft 4. The bar 33 is adjusted
by screw 38 so as to enable the bowl 31 to be moved nearer to or further from the
bowl 30 to suit the size of shaper employed, and the gauge or stop piece 17 and
rest 29 are likewise adjustable to correspond with the adjustment of the bowl 31,.
the screws 39 serving to secure the said parts when adjusted.
The side pieces or slips 40 are adjusted laterally by set screws 41.
For bending irons for the heels of boots and shoes, the bowls 30, 31, must advance
towards each other to give the requisite curve or inward bend to the extremities
of the iron, and as these lie nearer to each other than the mid portion, it is
necessary that the shaper should be removable to enable the iron when bent to be
removed.
To this end the bars 32, 33, carrying the said bowls are preferably caused to.
slide in ways in the frame 9 by means of suitable wedges or inclined surfaces 42
(see Figs. 4 and 5) actuated from the crank shaft 4, or carried by the sliding bed 6,
these said inclines engaging with pins or fingers 43 projecting from the underside
of the bars 32, 33, so as to cause the bowls carried thereby to advance towards
each other at the proper time to bend in the ends of the iron and give the formation
illustrated at Fig. 7. The shaper 12 in this case is mounted or fixed to the
upper end of a spindle 44 carrying at its lower end a bowl 45 and supported
and adapted to slide vertically in a bracket 46 attached to the sliding bed 6.
As the sliding bed moves forward towards the cutter, the bowl 45 engages with.
and rides over the fixed projecting part 47 which forces up the shaper through
an opening in the plate 48 and against the plate 49 where it is held until the
return of the sliding bed carries the bowl clear of the said part 47 and allows the
shaper to be drawn down again by spiral spring 50, whereupon the bent iron is
removed by the fingers or clearing blades 34 pivoted in a suitable position on
the frame so as to engage the ends of the iron as the shaper recedes from its
position.
Springs 51 may be employed to draw the bars 32, 33, back to their normal
positions, or the same result may be obtained by making the wedges or inclines 42
as shewn at Fig. 6.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
Firstly. In machines for making or forming irons for clogs or for the heels of
boots and shoes, an adjustable plate 10 bolted to the sliding bed, a shaper 12
constructed in three pieces, each detachable, adjustable guage or stop piece 17 and
rest 29, together with bowls or pulleys one of which is adjustable mounted on studs
at each side of the track of the shaper and means for cutting off the length of iron
to be bent all arranging and operating in the manner and for the purposes
substantially as herein shewn and described.

page_text: Secondly. The general arrangement, construction and combination of the
several parts comprising our improved machine for making irons for clogs and heels
of boots and shoes, substantially as herein shewn and described.
