Improvements in Boot-heel Breasting Machines.
I, OWEN ROBINSON, of Champion Works, Kettering, 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 :-
My invention relates to heel breasting machines and it comprises. improvements
whereby such machines are rendered more certain and efficient in operation than
heretofore.
According to my invention I arrange a guide on each side of the boot-heel, such
guides being adjustable to any width of heel and serving to enable the heel to be
placed in a central position relatively with the knife.
An adjustable automatic stop against which the heels to be breasted are placed
allows a certain quantity to be taken off by the knife.
An adjustable table capable of adjustment to the various pitches of heel is
provided for the heels to rest upon whilst being cut.
An adjustable pressure clamp adapted to be operated by a hand lever or other
means serves to press upon the heel, whilst being cut to prevent it altering its
position.
To enable my invention to be fully understood I will describe how it can be
carried into practice by reference to the accompanying drawings, in which :-
Figure 1 is a sectional front elevation of a machine constructed according to my
D

page_text: invention for breasting the heels of boots and shoes, the said machine being designed
to be operated by a treadle:
Figure 2 is a plan of the same:
Figure 3 is a vertical section on the line 3-3, Figure 1; and,
Figure 4 is a sectional plan, the section being taken on the line 4-4, Figure 3:
Figures 5 and 6 are respectively a side elevation and a front elevation of the
machine when designed to be operated by power.
Similar reference letters indicate similar or corresponding parts throughout the
drawings.
a is the table of the machine, and b the knife, which, in the machine illustrated
in Figures 1 to 4, is attached to a crosshead c of a frame having the side rods d, d
working through guides e, e on the table a and the crosshead f connecting the said
rods at their lower ends, the said crosshead f being directly connected to a treadle
(not shewn) by the rod g, which treadle serves to actuate the knife when depressed.
Springs h, h in the guides e, e serve to raise the said frame when the treadle is
released. In the machine shewn in Figures 5 and 6 the knife b is attached to a
slide c working in guides e, e and operated by a connecting rod g from the crank-
pini of a crank on a power shaft j revolving in bearings j, j.
k, k are the guides which I arrange on each side of the heel to be breasted, the
said guides being advantageously of the shape shewn clearly in Figures 2 and 4
and pivotted at k², k' to the table for supporting the heel so that they can be
adjusted to suit any width of heel and so as to enable the heel to be placed in a
central position relatively with the knife b. Bolts m, m pass through slots in the
guides k, k into the table and serve to clamp the said guides in the position in
which they have been adjusted.
n is the adjustable automatic stop against which the breast of the heel is placed
and the position of which stop determines the quantity to be cut off by the knife.
This stop n is carried by a lever o pivotted to the framing, the said lever being
advantageously caused to keep the said stop in contact with the heel when the
knife is in the raised position by means of a projection p on the back of the cross-
head or the slide c bearing against the said lever. When the knife is moved down
to cut the heel the projection p moves out of contact with the lever o, the weight
of the stop n causing it to move out of the way of the knife, this movement taking
place just after the latter has commenced to cut the heel. The position of the
stop n is advantageously adjusted by means of a nut g and a bolt g attached to or
formed in one with the said stop, the said nut being kept within a recess in the
lever o by a pin r engaging a groove in the nut.
The table 1, the upper surface of which is shaped to fit the heel, is capable of
adjustment at a slight angle relatively with the table a to suit the required pitch of
heel. This adjustment is advantageously effected by means of wedges s, & placed
between the said tables a and 1, the said wedges which are preferably connected
together by the part s¹ being held in the position in which they are adjusted by a
bolt passing through a slot in the said part s' and into the table a. t is a bolt
connected to the rear portion of the table and passing through a hole t' in the
table a, the said bolt serving to prevent any backward or forward movement of the
table upon the table a, a spring 2 being provided to allow the bolt to yield
when the wedges are adjusted. The pivot pins k¹, k' on the guides k, k pass through
the table and through slots in the table a and serve to prevent any side movement
of the said table 1.
u is the pressure clamp for holding the beel in position while being cut by the
knife b. In the machine shewn in Figures 1 to 4 this clamp is operated by hand,
it being jointed to a hand-lever u' pivotted at u² to the framing of the machine,
the pivot-piu being rounded as shewn to allow a certain amount of lateral movement
to the lever so that it can be moved to accommodate itself to large or small heels.
In the machine shewn in Figures 5 and 6 this clamp is arranged to be operated
automatically or by means of a treadle. In these figures the clamp u is provided
with a screwed shank u sliding through a crosshead and having screwed on to its

page_text: The
upper end a cap in such a manner that the rotation of the said cap in one or the
other direction allows of adjusting the clamp u according to the height of the heels
being-breasted. A nut u is provided to lock the screw of the clamp when adjusted.
The said crosshead is adapted to be moved down by the head of the crank-pin i
impinging against a lever u pivotted at wo¹ to the frame of the machine and provided
with a spring-arm a bearing directly upon the cap on the crosshead v.
crosshead is guided by rods y, y attached thereto and working through guide
bosses on the table a, springs, 2 being provided to raise the crosshead after
being lowered by the crank-pin i. ' is a crosshead attached to the lower ends of
the rods y, y to which a treadle can be connected when it is desired to operate the
clamp by the foot.
The operation of the machines hereinbefore described is as follows. The heel
to be breasted is placed upon the table between the guides k, k and with its
breast against the stop n, the said guides and stop being first adjusted so as to
ensure the placing of the heel centrally and so that the required quantity can be
taken off by the knife. In the machine illustrated in Figures 1 to 4, the clamp u
must then be brought down by the lever u' upon the heel so as to hold it firmly,
the foot-lever being finally depressed so as to bring down the knife and cut the
breast of the heel, but in the machine illustrated in Figures 5 and 6 the shaft j
being caused to revolve causes the crank-pin i to impinge against the lever w, which,
through the medium of the arm x and crosshead v, forces the clamp u down upon
the heel, the knife being also moved down to cut the same by the crank and rod g.
As hereinbefore described the downward movement of the knife in both forms of
machine allows the stop n to move out of the way of the knife. The heel having
been breasted is then removed and another one placed in position ready for the
next operation of the knife.
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 breasting machine the employment in combination with the breasting
knife of adjustable guides for ensuring the proper placing of the heels to be breasted
relatively with the knife, substantially as described.
2. In a heel breasting machine the combination of guides adjustable to the width
of the heel and of a stop against which the breast of the heel is placed and which
is adjustable according to the quantity to be cut off the heel, the said stop being so
arranged as to be moved out of the way of the knife as the latter moves down to
cut the heel, substantially as described.
3. In a heel breasting machine of the kind described in the preceding claiming
clause carrying the stop for the breast of the heel upon a pivotted lever against
which a projection on the crosshead or slide carrying the knife impinges so as to
normally hold the stop against the heel but which when the cutting knife moves
down allows the stop to move out of the way of the knife, substantially as
berein before described and illustrated in Figures 1 to 4 of the accompanying
drawings.
4. In a heel breasting machine a table for supporting the heels to be breasted
capable of adjustment by means of wedges, substantially in the manner and for the
purpose set forth.
5. In a heel breasting machine a holding clamp adapted to be operated by means
of a pivotted hand-lever substantially in the manner set forth with reference to
Figures 1 to 4 of the accompanying drawings.
6. In a heel breasting machine the knife of which is operated by a crank, a
clamp carried by and adjustable relatively with a guided crosshead, the said cross-
head being adapted to be operated in one direction by the crank-pin operating the
knife through the medium of a lever having a spring-arm or by a foot-lever and in
the other direction by springs, substantially as hereinbefore described and illustrated
in Figures 5 and 6 of the accompanying drawings.

page_text: 7. The manufacture and use of the improved heel breasting machines herein-
before described and illustrated in Figures 1 to 4 and Figures 5 and 6 of the
accompanying drawings.
