Improvements in Machines for Attaching Heels to Boots and Shoes,
and Inserting Slugs therein.
I, HENRY HARRIS LAKE, of the firm of Haseltine Lake & Co., Patent Agents,
45 Southampton Buildings, in the County of Middlesex, 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 consists of the use in a machine for attaching heels to boots and
shoes, of a staple containing box adapted to be embraced by a shoe and having
slots to receive the staples; a seat plate carried by the said box and provided with
elongated slots a series of staple drivers co-operating therewith and having
elongated heads to enter the said slots; a staple driver plate; a nail or slug
driver plate; a series of nail or slug drivers; a nail or slug box; a stud or bolt
connecting the said plate and box; and devices to actuate the said parts whereby
staples may be driven outwardly through the sole and into the heel from the inner
sole of the shoe and nails or slugs be driven into the tread end of the heel, as will
be described.
The invention also comprises the use in a machine for attaching heels, of a
staple containing box having slots to receive staples; a staple plate; a series of
staple drivers; a staple driver plate; a nail or slug box having a depending breast
gauge and corner gauges; a series of nail or slug drivers; and means to actuate
the said parts, as will be hereinafter described.
The invention also comprises the use in a machine for attaching heels to boots
and shoes, of a nail or slug box having a depending breast gauge and corner
gauges, and a catch to engage the rear part of the heel to suspend it from the
under side of the nail box, substantially as will be hereinafter described.
The invention moreover comprises the use in a heel nailing machine, of a
support for a shoe to be heeled; a head or cross beam; a hollow rotatable
internally threaded sleeve therein; and a bar or rod vertically adjustable therein;
a connected slug driver plate; slug drivers; a slug box; a bolt extended through
the same; and a spring located between the plate and slug box to keep the latter
separated from the plate, and the drivers retracted to leave space in the slug box
for the slugs, as will be hereinafter described.
In the accompanying drawings,
Figure is a front elevation showing a heeling machine embodying my invention
the head and parts in it being in section.
Fig. 1 is a partial section on the line ex of Fig. 1.
Figure 2 is a side view thereof partially broken away.
Figure 3 is an enlarged sectional detail of the staple and nail boxes and the
parts within them.
Figure 4 an upper side view of the nail or slug driver plate and nail box.
Figure 5 an under side view of the nail or slug box shown in Figure 4.
Figure 6 a right hand end view of the nail or slug box.
Figure 7 a top or plan view of the staple box over which the boot or shoe is
placed, the heel seat plate forming the top of the staple box being broken away.
The base or frame A is provided with suitable bearings to sustain a power
shaft A¹, provided with a balance wheel A³, fast and loose pulleys A', A*, and a
pinion A, as shown by dotted lines.
This pinion engages a toothed gear B, fast on the main shaft B', having a crank
Din B2 embraced by the strap of a connecting rod B³.

page_text: The base has erected upon it two uprights or rods C, C the upper ends of which,
reduced or shouldered, are extended through a head C' and have screwed upon
them suitable nuts C, to thus confine the head in position.
The head, as best shown in section, Figure 1,.receives a shouldered sleeve c, on
which preferably rests a washer c', against which bears the lower end of a strong
spring the upper end of the said spring, as represented receiving upon it a
washer c, which in turn is acted upon by suitable adjusting screws or devices e*,
the said spring being of great force so as to yield in case of excessive crushing
strain, it having no function to perform as a spring, but merely acting as a stop to
prevent upward movement of the sleeve during ordinary work.
The sleeve c at its inner side is threaded to receive a hollow bar or rod d,
which is prevented from turning in the head C' by a key d* as shown in Fig. 14.
The lower end of the sleeve c has fastened upon it a suitable hand wheel c³, see
Figure 1, rotation of the hand wheel causing the threads of the hollow bar or rod d
to raise and lower the same.
The lower end of the bar or rod d has screwed upon it a block d' having at its
underside a dovetailed groove, to receive a dovetailed projection e of a driver
plate e¹ shown best in Figures 1, 3 and 4.
The driver-plate provided with a series of usual drivers e, is provided centrally
with a hole to receive a bolt es, which is screwed into a nail or slug box f,
provided with suitable holes as f¹ see Figure 5, for the reception of nails or
slugs f³.
Between the driver-plate and the nail or slug box, the bolt e³ is surrounded with
a stiff spiral spring e*.
The hollow bar or rod d receives within it a rod n, the lower end of which bears
on the head of the bolt es, the said rod having a collar n', on which rests a spiral
spring the upper end of the spring abutting against a shoulder of the hollow bar
or rod the spring n³ assisting the rod n acting on the bolt e³, to keep the nail box
separated from the driver-plate e¹.
The nuts on the rod prevent it from dropping out from the spindle when the
plate e is removed.
The front end of the nail or slug box f, has attached to it a breast gauge f*
while at its rear side the said box has attached to it by a screw fe a spring dog or
holder which engages the rear side of the heel, the breast of which is placed
against the breast gauge.
The breast gauge is provided with two lips or corner gauges ƒ³.
Normally the lower ends of the drivers e stand in the holes f
The uprights or rods C act as guides for a reciprocating cross head D, to which
the connecting rod B³ is jointed.
This cross head D is represented as provided with an extension D', having a
dovetailed groove to receive the correspondingly shaped foot of a post D².
The cross head has an adjusting or stop screw O, the rotation of which in an
ear O' determines the position to be occupied by the post, the cross head also
having a locking device, shown as a cam lever pivoted at 10, and having an
eccentric or cam shaped end to engage the foot of the post and hold it in adjusted
position during the driving operation.
The post is hollow and receives the shank of the staple driver plate 9, which
shank is attached to the post by suitable bolts or screws.
The staple driver plate carries a series of staple drivers g', having their upper
ends cut away to leave oblong heads g, the ends of the said heads entering guiding
grooves g* in the staple box 93, the heads of the staples s resting upon the heads
of the drivers, as represented in Figure 3.
The staple box has a shank 9, which is extended down through the hollow
shank of the staple driver plate, the said shank entering a spring 9, which is
supported within the hollow post, the upper end of the spring receiving against
it an adjustable collar g' attached to the said shank, the spring g' normally acting
to keep the staple box elevated sufficiently above the staple driver plate to withdraw

page_text: the staple drivers sufficiently into the staple box to receive the heads of the staples
and let the latter stand with their points in the slots m of the heel seat plate`m²,
which acts as the top for the staple box.
The holes in the heel seat plate are oblong and the heads of the staple drivers
as they act to drive the staples into the heel, come up into the said holes and fit
them substantially snugly.
In practice the nails or slugs f' will be loaded into the nail or slug plate while
the latter is off the machine and overturned from the position Figure 3.
The nail box having been filled with nails or slugs, and staples having been put
into the staple box, the operator will place the shoe to be heeled over the staple
box and post, and will place the tread end of the heel with its breast against the
breast-gauge, making the dog' engage the rear end of the tread-lift.
With the heel applied to the nail-box as stated, the operator will insert the
dovetailed projection e into the dovetailed guide of the head or plate attached to
the block referred to.
Now the machine will be started, causing the rotating of the main shaft so that
it elevates the reciprocating cross-head, and in so doing, the heel is at first firmly
compressed between the staple box and the nail box, and in the further upward
movement of the cross head D, the staple drivers act to force the staples through
the usual inner sole and outer sole and into the heel from its seat end substantially
to its tread, and during the latter part of the movement of the staple drivers the
nail box rises about the stationary drivers, compressing the spring e³, the drivers e
acting upon the nails or slugs f, and driving them from the nail box into the tread
of the heel through the tread partially into the heel.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed as communicated to me by
my foreign correspondent, I declare that what I claim is :-
First. The use in a machine for attaching heels to boots and shoes, of a staple
containing box adapted to be embraced by a shoe and having slots to receive
staples; a seat plate carried by said box and provided with elongated slots; a
series of staple drivers co-operating therewith and having elongated heads to enter
said slots; a staple driver plate; a nail or slug driver plate; a series of nail or
slug drivers; a nail or slug box; a stud or bolt connecting the said plate and box ;
and devices to actuate the said parts whereby staples may be driven outwardly
