PROVISIONAL SPECIFICATION.
Improvements in Heel Attaching, Paring, and Breasting 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 has for its object to simplify the construction of heel-attaching,
paring and breasting machines.
In a machine constructed according to this invention I arrange the horn so that
instead of it being necessary, when adapting the machine for attaching different
size heels, to change the complete horn as has hitherto been the practice, it is only
necessary to change the head and nail drivers or plungers.
The horn in the usual manner is pivoted to the framing of the machine and is
bored out or otherwise recessed to receive a preferably helical spring and also to
receive the stem of the head upon which the spring is adapted to act so as to force
it outwards. The horn is slotted to receive a cotter for limiting the movement of
the head in relation to the horn.
The head is perforated in the usual manner to receive the nails, and the nail
drivers or plungers are each preferably provided with a head which is clamped
between two rings or collars which may be screwed or attached to the horn by
means of clips or other fastenings.
If desired the plungers may be secured to a single instead of a double ring or
collar and the connections between the plungers and collars may be slotted so that
one set or arrangement of plungers may serve for driving the nails for attaching
various size heels.
The movable plunger-head is preferably provided with a sleeve which closes-in
the plungers and collars.
When it is desired to adjust the machine for attaching a heel of a different size
to that for which it has previously been adjusted all that is necessary is to remove
the head and plungers and substitute for them others of the required size.
Where the plungers are mounted in slotted collars it is only necessary to remove
the head and substitute another of the required size the plungers in this arrange-
ment being able to accommodate themselves to the altered positions of the holes in
the head.
The breasting device consists of the ordinary foot-operated rack engaging with a
gear wheel with which engages a horizontal rack carrying the breasting knife. The
gear wheel and two racks are all supported in one casing so that the whole device
may be readily attached to or removed from the machine the framing of which
requires only to be provided with holes for the reception of the necessary bolts and
one for the accommodation and guiding of the horizontal rack.
To the knife holder is attached the heel support which is provided with a curved
arm adapted to strike against a stop movable on the casing so that it may be
adjusted to suit heels of different sizes.
The paring knife carrier preferably of the construction described in the Speci-
ication to Letters Patent No. 6950 may be mounted on a pin carried in a link
pivotted to an arm secured to the shaft which is moved longitudinally for forcing
he nails into the heel.

Improvements in Heel Attaching, Paring, and Breasting Machines.
I, 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 has for its object to simplify the construction of heel-attaching,
paring and breasting machines.
In a machine constructed according to this invention I arrange the horn so that
instead of it being necessary, when adapting the machine for attaching different
sized heels, to change the complete horn as has hitherto been the practice, it is only
necessary to change the head and nail drivers or plungers.
In the accompanying drawings
Figure 1 is a view of the complete horn.
Figure 2 a similar view of the horn but taken in a plane at right angles to that of
Figure 1 and with a portion broken away.
Figure 3 is a similar view to Figure 1 but is in section.
Figure 4 is a detail of the horn fittings illustrating the connection between the
head and the horn.
Figure 5 is a view of the complete machine so far as the present improvements
are concerned,
Figure 6 being a detail upon a larger scale of the breasting and paring knives
and their operating mechanism.
Figure 7 is a vertical section upon line y y of Figure 6.
Like letters indicate like parts throughout the drawings.
The horn A is in the usual manner pivotted to the framing B of the machine and
is bored out or otherwise recessed at A¹ to receive a preferably helical spring C
and also to receive the stem D' of the head D upon which the spring is adapted to
act so as to force it outwards. The horn is slotted at A2 to receive a cotter E for
limiting the movement of the head in relation to the horn.
The head D is perforated at D2 in the usual manner to receive the nails and the
nail drivers or plungers F which are each preferably provided with a head F¹
which is clamped between two rings or plates G and H which may be screwed or
attached to the horn by means of clips I or other fastenings.
If desired the plungers may be secured to a single instead of a double ring or
plate and the connections between the plungers and plates may be slotted as at G¹
so that one set or arrangement of plungers may serve for driving the nails for
attaching various sized heels.
The movable plunger-head is preferably provided with a sleeve K which closes-in
the plungers and collars.
When it is desired to adjust the machine for attaching a heel of a different size
to that for which it has previously been adjusted all that is necessary is to remove
the head and plungers by springing the clips I and substitute for them others of the
required size.
Where the plungers are mounted in slotted collars it is only necessary to change
the head and substitute another of the required size the plungers in this arrange-
ment being able to accommodate themselves to the altered positions of the
holes in the head as will be well understood by reference to the accompanying
drawings.
The breasting device consists of the ordinary foot-operated rack L engaging
with a gear wheel L' with which engages a horizontal rack M carrying the
breasting knife N. The gear wheel L₁ and two racks are all supported in one
casting so that the whole device may be readily attached to or removed from
the machine the framing of which requires only to be provided with holes for

page_text: the reception of the necessary bolts and for the accommodation and guiding
of the horizontal rack M.
To the knife holder M' is attached the heel support P which is provided
with a curved arm Pl adapted to strike against a stop P³ movable on the
casing so that it may be adjusted to suit heels of different sizes. This stop is
pivotted at P3 and has a slot P4 through which passes the screw Ps by which
the stop P may be fixed in any required position for the regulating of the
arm P
The paring knife carrier Q preferably of the construction described in the Speci-
fication to Letters Patent No. 6950 may be mounted on a pin R carried in a link S
pivotted to an arm or crank T secured to the shaft U which is moved longitudinally
for forcing the nails into the heel.
The shaft U may be rotated either by pulling round by hand the movable
framing V which is secured at V₁ to the shaft U in such a manner that while
the shaft may move longitudinally through the frame V it must rotate with it,
or by means of the pulley W to which the other end of the framing V is fixed
and which by means of a strap W₁ may be connected with a foot treadle or
other means for providing the rotary motion. The operation of this portion of
the invention will be well understood by those versed in this class of machines
and would be as follows:-
:-
The head D of the horn A. Figures 1, 2 and 3 is charged with nails which
are placed in the holes D' and upon the head is then placed the boot X and the
shaft U with its appurtenances is then moved up so as to bring the block Y
Figure 6 up against the heel which it then forces forward upon the nails which
as the head D recedes before the pressure as the spring C collapses, project
beyond the head and enter the sole and heel of the boot until the head Ď is
moved so far back upon the horn that the nail drivers F reach the outer ends
of the holes D2 thus driving the nails entirely home. The longitudinal move-
ment may be imparted to the shaft U by one of the well known devices
for this purpose say for preference that set forth in British Letters Patent
No. 531880
The heel being thus secured upon the boot the paring knife Q₁ Figure 6 may be
brought round the heel by the movement already described, and the breasting
knife N may be brought forward by the rack and wheel mechanism L L' and M,
the rack L being operated preferably by a foot-treadle in the manner indicated in
my previous Specification No. 531880.
The arm P of the heel support P is as already explained retained in its
proper position according to the size of the heel by the stop P2 which is fixed
by the screws P3 and P to any suitable part of the bracket O; the heel
support P is pivotted at P6 to the knife holder M¹ and serves to support the
heel while the latter is being fixed to the boot. When however the breasting
knife N is moved forward by the rack and wheel motion the heel support P is
allowed to fall down out of the way of the breasting knife as it moves forward
away from the stop P2 which is a fixture the curve of the arm P' regulating
the amount of this movement.
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 machine for heeling boots and shoes the combination with the boot
aupporting horn of a detachable head whereby the machine is adapted for nailing
heels of different sizes without the necessity for changing the whole horn as
described.
2. In a machine for heeling boots and shoes the combination with the horn A of
a detachable head such as D and slotted rings or plates such as G G' substantially
as and for the purpose described and illustrated in Figure 3 of the accompanying
drawings.

page_text: 3. In a machine for heeling boots and shoes the combination with the horn A
of a movable head such as D slotted ring or plate such as G G' ring H and spring
clips I substantially as described and illustrated in Figure 3 of the accompanying
drawings.
4. In a machine such as described the combination with the paring knife carrier Q
and heel plate shaft U of a crank or arm T and link S whereby the rotary motion
of the shaft U is imparted to the paring knife substantially as described and
illustrated in Figures 6 and 7 of the accompanying drawings.
5. In a machine such as described imparting motion to the paring knife directly
from the heel plate shaft.
6. In a machine such as described the combination with a pivotted heel support
such as P of a curved arm P¹ and stop P2 substantially as and for the purpose
described and. illustrated in the accompanying drawings.
7. Placing the breasting knife and its operating and controlling mechanism in an
independent frame or casting such as O substantially as and for the purpose
described.
