We, CHARLES HENRY DALE and FREDERICK JAMES DALE, of Newarke
Street, Leicester, Boot and Shoe Engineers, do hereby declare the nature of this
invention to be as follows:-
This invention has reference to machinery for attaching heels to boots and shoes
and embodies improvements as hereinafter described.
In heel attaching machines as at present constructed the to-be-attached heel is
placed upon a boot supported on the usual perforated boot carrying block and the
said beel is clamped or compressed thereon by the lowering of a block on the end
of a screw, supported in a crosshead at the upper part of the machine.

attached.
This
According to our invention we provide for raising the usual perforated boot
carrying block in relation to the clamping block on the end of the screw before
mentioned while the latter remain in the same position during the attaching process
but can be raised or lowered for varying heights of heels as heretofore.
To carry out our invention the tubular pillar, to whose upper end is attached the
perforated boot carrying block before mentioned, and in which is located the ram
or plunger which drives the nails into the heel, is connected to or actuated by one
or more levers or equivalent mechanism, operated by a lever or handle located at
preferably the side of the machine.
The operator by retaining hold of this latter lever or handle keeps the heel
compressed during attachment, but upon releasing the handle, the pillar will drop
of its own weight and allow the boot to be removed. The handle or lever may if
desired be connected to a treadle and actuated by the foot of the operator.
The invention also includes means for automatically delivering the nails from
the feed plate into the perforations in the boot carrying block herein before
mentioned.
The nails are placed in the feed plate by hand in the usual manner, a slide or
shutter thereunder preventing them falling through.
The feed plate is then placed over the perforated boot carrying block and instead
of it being necessary to withdraw the slide or shutter by hand, it is provided with a
lip which, engaging the edge of the former, moves the said slide sufficiently to allow
the said pins to fall into the perforations in the boot carrying block and on to the
usual driving pins.
A spring or other elastic means is provided to return the slide or shutter to its
original position.

Improvements in or relating to Machines for Attaching Heels to
Boots and Shoes.
We, CHARLES HENRY DALE and FREDERICK JAMES DALE, of Newarke
Street, Leicester, Boot and Shoe Engineers, 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 reference to machinery for attaching heels to boots and shoes
and embodies improvements as hereinafter described.
In heel attaching machines as at present constructed the to-be-attached heel is
placed upon a boot supported on the usual perforated boot carrying block and the
said heel is clamped or compressed thereon by the lowering of a block on the end
of a screw, supported in a crosshead at the upper part of the machine. This
necessitates the raising and lowering of the screw and block each time a heel is
attached.
According to our invention we provide for raising the usual perforated boot
carrying block, in relation to the clamping block on the end of the screw before
mentioned while the latter remain in the same position during the attaching process,
but can be raised or lowered for varying heights of heels as heretofore.
To carry out our invention the tubular pillar, to whose upper end is attached the
perforated boot carrying block before mentioned, and in which is located the ram
or plunger which drives the nails into the heel, is connected to or actuated by one
or more levers or equivalent mechanism, operated by a lever or handle located
preferably at the side of the machine.
The operator by retaining hold of this latter lever or handle keeps the heel
compressed during attachment, but upon releasing the handle, the pillar will drop
of its own weight and allow the boot to be removed. The handle or lever may if
desired be connected to a treadle and actuated by the foot of the operator.
The invention also includes means for automatically delivering the nails from
the feed plate into the perforations in the boot carrying block hereinbefore
mentioned.
The nails are placed in the feed plate by hand in the usual manner, a slide or
shutter thereunder preventing them falling through.

The feed plate is then placed over the perforated boot carrying block and instead
of it being necessary to withdraw the slide or shutter by hand, it is provided with
a lip which, engaging the edge of the former, moves the slide sufficiently to allow
the said pins to fall into the perforations in the boot carrying block and on to the
usual driving pins.
A spring or other elastic means is provided to return the slide or shutter to its
original position.
The invention will be understood from the following further description in
reference to the accompanying drawing wherein,
Figure 1 is a front elevation of so much of a heel attaching machine as is
necessary to show our invention applied thereto.
Figure 2 is a view partly in section and partly in elevation of the boot carrying
block, pillar, socket and lifter.
Figure 3 is a detail view of the lifter, tubular pillar and plunger therein.
Figure 4 is a side elevation of part of the machine showing the handle H, guide
therefor, and feed plate.
Figure 5 is a plan showing the handle guide and stop for feed plate.
Figure 6 is an elevation of the tubular pillar, boot carrying block thereon, and
showing the feed plate and shutter in section.
Figure 7 is a plan of the feed plate and shutter.

page_text: A is the usual perforated boot carrying block upon which a boot or shoe is placed
in the well known manner to have a heel attached thereto.
In machines of ordinary construction the block B on the screw B' which passes
through the crosshead C, is lowered on to the beel to compress it while, the heel
pins are driven through the latter and the said block is raised to permit the boot or
shoe to be removed after the heel is attached.
This lowering and raising of the block B by means of the wheel B' at each heel
attaching operation entails considerable labour and loss of time.
By means of our invention the block B, after having been once fixed in position
relatively to the block A, need not be again removed, (i.e. raised or lowered) for
the attachment of any subsequent number of heels of the same height.
It is obvious that heels of different heights would render it necessary to corre-
spondingly adjust or alter the position of the block B in relation to the block A ;
this, however, would be the work of but a moment.
In order to avoid raising and lowering the block B as described we provide for
elevating and lowering the boot carrying block A relatively thereto, this movement
being much more speedily effected and entailing less labour. For this purpose the
block A is carried upon the upper end of a tubular pillar D whose lower portion, of
reduced diameter, is located within a tubular socket E on the bed plate E'..
The lower end of the tubular pillar D rests upon a lifter comprising two horns F,
Figs. 2 and 3, projecting from a boss F1 keyed upon a shaft G, carried in a
sleeve G¹ and upon the outer end of the said shaft is also keyed a handle H.
Assuming a boot to have been placed over the boot carrying block A and a heel
placed upon the said boot and it is now desired to compress the said heel between
the blocks A and B, the operator takes hold of the handle H and by giving it a
partial revolution moves it into the position shown in the dotted lines in Figure 4.
This motion imparts a similar movement to the shaft G whereupon the horns F
are raised, thereby simultaneously elevating the tubular pillar D and block A into
the position indicated in Figure 2 when the heel will be clamped in position for
the heel pins to be driven through the same by a plunger J, operated from the
usual treadle (not shown in the drawings) in the well known manner.
While the operator holds the handle H in the position mentioned, the heel will
remain compressed between the blocks A and B but upon releasing the said handle
the tubular pillar D, of its own weight will fall within the socket E and upon so
doing will return the handle H to its original position, so that the boot or shoe can
be removed.
The said handle H moves within a guide plate H' Fig. 5, provided with a tubular
socket H passing over the vertical rod C₁ and connected thereto by a bolt H' or
equivalent means.
To deaden the jar or shock consequent upon the handle H returning to its
original position after an attaching operation as described, one end of the guide H¹
is provided with a rubber or leather buffer H' screwed or otherwise connected
thereto.
It is obvious that the shaft G may be operated by a treadle either by connecting
it to a short arm thereon or to the handle H.
The present invention also includes means for automatically delivering the nails
from the feed plate into the perforations in the boot carrying block A herein before
mentioned so as to supply the said block with pins for each attaching operation.
The nails are placed in the holes in the feed plate in the usual manner.
Referring to Figures 4. 6 and 7. K is the feed plate provided with holes K' for
the reception of the heel pins K', and L is the shutter or slide thereunder being
also provided with a corresponding number of holes and connected to the former
a screw L' passing through a slot L' in the said shutter and into the said feed
plate.
by
The feed plate K is fixed in position by a wing nut M tightened over a screw
bolt M on a borizontal-extension M' of a tubular socket M, movably carried on the
vertical rod Cl.Figures 1 and 4.

page_text: The feed plate K is maintained at the side of the machine away from the block A
by a spring N, one end of which is connected to a hook N₁ on the horizontal
extension M and the opposite end is attached to a hooked arm H³, screwed into the
fixed socket H'.
In their normal positions the shutter or slide L and the feed plate K оссиру the
relative positions indicated in Figure 6 so that when the heel pins are placed in the
holes in the feed plate the heads thereof will rest upon the shutter or slide Las
shown.
In order to deliver the heel pins K³, from the feed plate K into the holes in the
boot carrying block A, the feed plate is swung round on its socket M and over
the block A so that the downwardly turned edge or lip L³ of the slide or shutter
bears against the back of the block A as in Figure 6.
Upon the operator pressing the feed plate K still further forward so as to move
the screw L' within the slot L', the holes in the feed plate are brought immediately
over those in the shutter or slide L so that the heel pins K' therein immediately fall
through and into the openings in the boot carrying block A in the well known
manner.
Upon the operator releasing hold of the feed plate after the delivery of the heel
pins as described, a spring L* interposed between the slide and feed plate and
located in a cylindrical cavity in the latter, causes the said slide and feed plate to
at once assume their previous positions as in Figure 6, while the spring N almost
simultaneously withdraws the feed plate away from the block A so as to be in
proper position for re-filling.
A stop M is formed on the socket H' to limit the return movement of the feed
plate K after delivering the heel pins.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. A heel attaching machine in which provision is made for raising the perforated
boot carrying block A relatively to a stationary block B or its equivalent for the
purpose described.
2. In a heel attaching machine the combination with an adjustable block B or its
equivalent of a movable perforated boot carrying block A and means for raising the
block A relatively to the block B for the purpose described.
3. In a heel attaching machine the combination with the block B or its equivalent
of a movable perforated boot carrying block A, tubular pillar D, socket E, horns F,
shaft G and means for actuating the said shaft substantially in the manner and for
the purpose described.
4. In a heel attaching machine the combination with the block B or its equivalent,
of a perforated boot carrying block A, tubular pillar D, socket E, horns F, shaft G
and handle H substantially as and for the purpose described and illustrated in the
accompanying drawing.
5. In a heel attaching machine the combination with the perforated boot carrying
block A of a perforated feed plate such as K and correspondingly perforated
spring-controlled slide or shutter such as L constructed and operating substantially
in the manner and for the purpose described and illustrated in the accompanying
drawings.
6. The improved heel attaching machine substantially as described and illustrated
in the accompanying drawing.
