PROVISIONAL SPECIFICATION.
Improvements in Heel Building or Attaching Machines.
I, FREDERICK CUTLAN of Castle Hill, Wellingborough, in the County of
Northampton, Engineer, do hereby declare the nature of this invention to be as
follows:-
This invention relates to improvements upon heel building or attaching machines
and has reference to the adjustment of the press block according to the height of
heel to be dealt with. In machines for this purpose previously constructed it has
been the custom to adjust the press block by a somewhat elaborate arrangement of
nechanism which four screws and eight nuts had to be adjusted whereas by my
present invention I can produce a simplified mechanisin which can be adjusted by a
single nut.
In carrying out this invention I prefer to proceed as follows:-
The plunger to which the press block is attached is carried in a screw-threaded
sleeve a nut upon which working in a suitable opening or recess in the framework
giving the required adjustment to the plunger and press block. The plunger at its.
outer end is pivotted in the end of the operating lever; the lever carries studs or
pivots by which it is connected to two links the other ends of which are pivotted in
the head of the before described screw-threaded sleeve. The lever end, or ends if
it be forked, is or are preferably made circular so as to fit snugly against the end
of the sleeve and the arrangement is such that the distance between the pivot
centres of the lever and the pivot centres of the links form crank arms which when
the lever is operated force the plunger in or out as required.

Improvements in Heel Building or Attaching Machines.
1, FREDERICK CUTLAN, of Castle Hill, Wellingborough, in the County of
Northampton, Engineer, 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 relates to improvements upon heel building or attaching machines
and has reference to the adjustment of the press block according to the height of
the heel to be dealt with. In machines for this purpose previously constructed it
has been the custom to adjust the press block by a somewhat elaborate arrangement
of mechanism in which four screws and eight nuts had to be adjusted whereas by
my present invention I can produce a simplified mechanism which can be adjusted
by a single nut.
In carrying out this invention I prefer to proceed as follows
:-
The plunger to which the press block is attached is carried in a screw-threaded
sleeve a nut upon which working in a suitable opening or recess in the framework
giving the required adjustment to the plunger and press block. The plunger at its
outer end is pivotted in the end of the operating lever; the lever carries studs or
pivots by which it is connected to two links the other ends of which are pivotted in
the head of the before-described screw-threaded sleeve. The lever end, or ends if
it be forked, is or are preferably made circular and may fit snugly against the end
of the sleeve and the arrangement is such that the distance between the pivot

page_text: centres of the lever and the pivot centres of the links form crank arms which when
the lever is operated force the plunger in or out as required.
In the accompanying drawings Sheet 1 represents the invention as applied to a
heel attaching machine and Sheet 2 to a heel building machine.
Figure 1 is a side elevation of those parts of a heel attaching machine to which
the invention appertains.
Figure 2 being a view looking upon the outer end of the plunger the lever or arm
which operates it being turned down.
Figure 3 is a vertical section of a portion of the plunger and its operating
mechanism, and
Figure 4 is a horizontal section of the same.
Figure 5 is a side elevation partly in section of the invention as applied to a heel
building machine the plunger being shown in its raised position, and
Figure 6 is a similar view of the same machine the plunger being shown in its
lowered position.
Like letters represent like parts throughout the drawings.
A is the plunger which carries the press block B, C is the screwed sleeve through
which the plunger A passes, D is the nut which works upon the outside of the
sleeve C and is prevented from longitudinal travel by being fitted in the recess E¹
in the frame E. This nut may be provided with flats to turn it by but I find a
convenient arrangement is to have the holes D in its periphery into which a pin
wrench may be inserted for the purpose of turning it. E is a stud projecting from
the frame E and entering a hole in the head of the sleeve C to keep it from
turning C are the sides of the jaw formed upon the head of the sleeve C.
In the end of the plunger A is placed the pin F which enters holes in the
preferably circular jaws G of the arm or lever G. The jaws G¹ have projections
or pins G2 which engage with holes in the links H which are jointed to the plunger
jaw C by the pins C. It will thus be seen that the pins G and F form in effect
a crank which when turned will impart longitudinal movement to the plunger A,
but owing to the fact that the pin F can only travel in a horizontal plane the other
centre of the crank, namely the pin G' must be capable of rising and falling to
accommodate the fixed path of F; thus accommodation is provided by the links H
whose outer ends can rise and fall as required. The operation is as follows:-
:―
The plunger A being connected by the pin F to the jaws G¹ of the lever G and
the lever G being connected by the pins G to the links H, which in their turn are
connected by the pins C with the jaws C2 of the sleeve C, it will be seen that if
the sleeve is moved in or out by the turning of the nut D the plunger must partake
of the same alteration in its position without reference to any movement of the
arm G. This is precisely what is required for the purpose of adjusting the position
of the press block B so that to adjust the normal distance between the press
block B and the fixed heel plate I all that is necessary is to turn the nut D in
either direction according as the block B is to be brought nearer to or farther
from I. The operation of the arm G is as follows:-
When in its raised position shown in Figures 1, 3 and 4, the plunger A is with-
drawn to its fullest extent and when in its lowest position as in Figure 2 the
plunger A would be extended to its fullest extent and the press block B moved
forward as near to as possible unless recourse were had to the nut-D.- The
arm G being in its raised position Figure 3 and it being desired to move forward
the plunger A the arm is pulled down by the operator and the pins G acting as a
movable fulcrum, the jaws G' serve as cranks and operating upon the pin F force
the plunger forward in a horizontal plane the pins G by the accommodation of the
links H rising so far as may be necessary. With the arm G in a horizontal
position the centre F would have been moved inwards to approximately the position
of the centre G the plunger being then approximately at half stroke; turning the
arm G to its downward position of Figure 2 would complete the stroke.
The construction and operation of the heel building machine Figures 5 and 6
are so far as this invention is concerned the same as those just described with

page_text: reference to the heel attaching machine excepting that the arm G is adapted to
operate in different positions and owing to the fact that the press block B can be
readily adjusted by screwing it on to or off the plunger A as indicated in the
drawings the sleeve C and nut D may be dispensed with. The other parts are the
same, the stops K being provided to restrict the movement of the arm G with
the proper limits. It will be understood however that if desired the sleeve C and
nut D may be employed in the heel building machine in the same manner as in the
heel attaching machine.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. In a heel building or attaching machine the combination with the plunger A
of an adjustable sleeve such as C substantially as and for the purpose described and
illustrated in the accompanying drawings.
2. In a heel building or attaching machine the combination with the plunger A.
of a screwed sleeve such as C and nut D substantially as and for the purpose
described and illustrated in the accompanying drawings.
3. In a heel building or attaching machine the combination with the plunger A
and an adjustable sleeve such as C of the lever arm such as G pins or pro-
jections F G2 and C and links H the whole constructed and operating substantially
as and for the purpose described and illustrated in the accompanying drawings.
4. The combination and arrangement of parts constituting the complete adjusting
and operating mechanism for heel attaching or building machines substantially as
described and illustrated in the accompanying drawings.
Dated this 15th day of August 1892.
