IMPROVEMENTS IN HEELING MACHINES
Year: 1887

page_text: Date of Application, 27th June, 1887
Specification Accepted, 29th July, 1887.
We THOMAS HENRY SALMON and FRANKLIN JACKSON trading as Salmon and
Jackson of the Victoria Works Kettering in the county of Northampton Engineers do
hereby declare the nature of this invention for IMPROVEMENTS IN HEELING MACHINES
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 improvements in heeling machines for shaping
either separately or in conjunction with the attachment of the heel, the heels of boots
or shoes.
We find it advantageous in carrying out our invention to construct a machine in a
similar manner to that described in the Patent granted to Thomas Salmon dated the
11th day of February 1885 No. 1896 in which a heeling or heel attaching and
breasting machine is described.
In carrying our improvements into effect we find it advantageous to employ a
similar attaching and breasting device to that shown in the Specification before
referred to but we have found that it is desirable to employ in combination with the
breast cutter of a guard which can be made adjustable by a screw or other suitable
means so that when the knife is brought into operation the guard descends at the
same time and comes into contact after the heel has been breasted with what is
termed the waist of the boot or shoe.
The employment in combination with the breasting knife of a guard so described
prevents the breasting knife from cutting into the waist of the boot during or
previous to the heeling operation. This heeling operation for curving or shaping the
heels is effected by the movement of a lever which is connected to a rack operating a
train of gearing terminating in a centrally arranged quadrant or wheel carrying at
one extremity a trunnion this trunnion carries a guide or crosshead which is received
by an extension of a carriage provided with friction rollers. These friction rollers
run with the carriage around the heel of the boot or shoe upon a table but they adapt
themselves in such partial rotation by means of a track or guide which track or guide
is of such a shape approaching or nearly so the heel of the boot as to guide the

page_text: carriage in its radial course. This latter movement is effected by a lever or it may
be by other suitable means but the carriage so actuated comes in contact with external
or internal dummy guides through the intervention of friction rollers with their axes
at right angles to the axial line of the friction rollers which are attached to the
carriage as herein before described. This carriage is provided with a slide rest
carrying a head, at the upper extremity of which is a pivot which carries a shoe.
This shoe is suspended from the head and it is provided and arranged in such a
manner as not only to be forced outwards by a spring from the head but it has
provided intermediately a bracket pivotted to the shoe and carrying a knife corre-
sponding with the shape it is desired to cut. Attached to this bracket is a guide
which traverses the top piece block or former, attached to the end of the plunger
spindle, thus giving the required shape to the heel. The paring knife rests against
a guard which traverses the seat of the boot or shoe and is adjustable from its
carrier whereby the angle of the knife is predetermined and set.
The boot or shoe is placed upon the horn in the usual manner and is arranged
upon a sliding traveller in order that it may be easily put in position or withdrawn
after the heeling operation. As soon as the operation is finished the head carrying
the shoe and knife together with the jigger can be readily detached from the carriage
but in operation it is not free to move outwardly as in order to effect this part of
our invention we provide at the side of the head a pawl engaging with a tooth or
stop formed upon the carriage. It will thus be seen that the head can be slid into
the carriage and locked in the manner described or on the other hand it may be
wholly or partially removed by releasing the pawl before referred to.
In order that our invention may be more fully understood we will now proceed to
describe the same with reference to the accompanying drawings.
the cam or
Figure 1 is a side or it may be termed a front elevation in which a
tappet on the end of a lever for depressing the plunger b carrying the knife 6¹ and
the breast guard . The lever c is for securing the heel but as this has been described
and shown in Salmon's Specification before referred to it is unnecessary to refer
further thereto. The other lever is that by which the heel-paring operation is
performed. It is pivotted at d¹ and by a link e it is connected to a rack f sliding
and being guided by the clips f¹f as shown in Figure 2 which is a part sectional
elevation.
Figure 3 is a plan thereof partly in section. The rack f gears with a pinion g
which pinion engages with another pinion with which engages another pinion i
which drives the carrier wheel j. This carrier wheel j has provided an arm carrying
a trunnion upon which is free to turn a crosshead or guide. It is upon the table
and the cross head j³ before referred to that the carriage works. It is provided with
friction rollers m to run upon the table & horizontally but its movement in a partially
radial direction is determined by supplementary friction rollers n engaging with the
dummy guide or guides for internal or o for external guidance, therefore it will be
observed that in traversing the path of the cutting process that the cross bar j³ and
with it the carriage will be reversed when in the opposito position, and after the
cutting has been effected.
It is to this carriage that the head p is connected. It is secured to the carriage by
the pawl as shown in the plan Figure 3, side elevation Figure 4, and front view
Figure 5. The pawl q is advantageously pivotted to the head at q whilst the free end
engages with the tooth or stop on the carriage 1. To the pivot q' is the shoes and it
is forced outwards by means of the spring s'. This outward pressure causes the
jigger t to traverse the seat of the boot and it is against this jigger that the knife u
rests, it is attached by any suitable means to the shoe s. The guard u is attached
by screws or other suitable means to the bracket or carrier pivotted to the shoe
at we as shown more clearly in Figures 1. 2 and 4.
In Figure 2 we have shown attached to the head pa bracket r provided with a
stop or hook against which a projection y on the guard t will engage in order to
limit the radial travel (or it may be horizontal) of the shoes and with it the knife and
knife carrier.

page_text: Having now particularly described and ascertained the nature of our said invention
and in what manner the same is to be performed we declare that what we claim is
First. In machines for shaping the heels of boots and shoes the employment of a
track or dummy partially surrounding the boot or shoe whereon a carriage works
actuated by gearing substantially in the manner herein set forth with reference to the
accompanying drawings.
Second. Attaching the carriage upon a guide or crosshead the latter being
connected to a trunnion 2 on the arm of the wheel or quadrant ; the latter being
j
actuated by a lever through the intervention of gearing substantially in the manner
herein described and illustrated with reference to Figures 1 and 3 of the accompanying
drawings.
Third. In combination with the radially sliding carriage the combination there-
with of friction rollers and guides and dummies for adapting the movement of the
carriage approximately to the shape of a heel seating substantially in the manner
herein set forth.
Fourth. The employment of a carriage provided advantageously with friction
wheels the said carriage working in and upon the table and free to adapt itself in its
radial movement by the pattern or dummy herein referred to and substantially in the
manner herein set forth.
