PROVISIONAL SPECIFICATION.
An Improved Machine for the Manufacture of Boots and Shoes.
I, AUGUSTO SANDINO, Director of La Société N. Farina y Cia. of Corunna,
in the Kingdom of Spain, Manufacturers, do hereby declare the nature of this
invention to be as follows:-
My invention relates to a machine for connecting the uppers of boots and shoes
to the soles in the manner described in the Specification of former Letters Patent
granted to me dated 19 August 1889, No. 13072.
The machine is constructed of a standard having four arms arranged in the form
of a cross, the side arms being provided with two bearings in which are located the
ends of a horizontal screw, the arm at the rear having a bearing which receives a
hollow threaded shaft or nut, and the front arm carrying a plate secured thereto by
means of a bole and a pin. At the junction of the back arm with the three other
arms it is provided with a vertical socket in which is loosely fitted a round pin.
When using the machine the sole made with a groove all round it, is first placed
upon a false metal sole, the last is placed upon the boot sole, and all three are
firmly secured. together by means of a screw and nut. The last is provided at its
upper part with a metal plate formed with a recess which prevents the head of the
screw from moving and with a nut in which works a screw. The loose portion or
instep of the last is applied in the usual way by the use of a wedge. The last is
then covered with leather which is carefully stretched at all parts and then secured
by sewing the lower edge of the leather all round to the false sole, provided along
its border for this purpose with a line of holes; the thread is sufficiently tightened
for the leather to closely hold to the last and the leather is still further stretched
by the loose portion of the last being operated upon by the wedge which is forced
in by means of the screw. The required curve is, at the same time, given to the
sole by causing it to conform exactly to the shape of the last through the medium
of three screws, operated by a suitable key.
The boot thus prepared is then placed on the machine by passing the socket
which forms the base of the nut which secures the last over the head of the said
round pin, and then fixing it thereto with a bayonet joint formed by three projec-
tions on the pin entering three corresponding slots formed in the bottom of the
socket.
The lower end of the pin is flattened and embraced by a fork on the end of a
lever, the head of which consists of two cylindrical portions located in similarly
shaped recesses made in the bottom of the vertical socket, so that the fork can
freely turn around the horizontal axis common to the head and to its cylindrical
bearing.
The two portions of the fork are connected by a bolt and a screw; the bolt is
eccentric and passes into an eye in the end of the pin. By this construction if the
lever be pressed down it will cause the base of the nut-socket to press tightly upon
the top of the socket in the standard and the boot thus becomes fixed in a convenient
position for being operated upon in the following manner.
The entry of the upper into the groove at each side of the sole is ensured by
means of plates carried by brackets jointed to the plate upon the front ann and
moved by means of two nuts working over a screw, which nuts can be caused to
approach each other. The leather upper is then similarly forced into the groove
at the heel, by means of a plate set in a block or bearing which is moved forward
by the combined action of a screw and its nut. As soon as the plates commence
to enter the groove the threads which attach the leather to the false sole are cut
which allows the leather to enter the groove.

page_text: When the three plates have entered the groove as far as they can go a metallic
or other cord is brought against the groove in the sole; it is then passed over two
rollers and its ends, guided by grooves, are each threaded through the transverse hole
in the waist of the sole: the ends are then attached to cord-carriers and are fastened
to the nuts or carriages by passing the cord through a slit arranged for that purpose.
The nuts are now caused to move apart whereby the two ends of the cord will be
simultaneously drawn along and the said cord consequent upon its passage over
the rollers will, with the leather, enter the portion of the groove at the toe end
of the sole.
After the cord and the leather have reached the bottom of the groove at the toe
the cord is slackened upon the rollers to allow of it being removed therefrom; the
nuts are then continued to be moved away from each other which causes the cord
and the leather to completely enter the whole of the side portions of the groove
comprised between the toe and the transverse hole. The cord is then slackened
which allows of separating the cord-carriers from the nuts; the two ends of the
cord are then brought round the heel and passed over the heel-plate so as to allow
the cord-carriers to be applied to the back nuts.
The nut which turns in the back bearing has a bevel wheel on its exterior which
latter, when rotating, it draws along by means of a sliding snug. The screw is
attached to the block or bearing through a plate thereon, the said block and plate
are prevented from turning by a pin while they are capable of a rectilinear
movement. This block serves as a bearing for a shaft, one end of which is screw-
threaded, and the other is provided with a shoulder and a pin. On the threaded
part is keyed a pinion and another pinion is arranged opposite to it and encloses
the shoulder by means of a circular plate fixed to the pinion by two screws,
the said plate being formed on a sleeve capable of rotation upon the pin and
screw-threaded on its exterior in the same direction as the shaft.
The bevel wheel which is constantly acted upon by a spring is, when the
screw is home, in gear with the pinions which project through openings in
the plate which beyond the said openings is provided with two grooves in which
slide ribs upon the two back nuts. These nuts thus guided are forced to recede
from each other at the same time that the heel-plate leaves the groove and
the leather, when the nut is caused to revolve in the required direction to draw
back its screw.
This movement is communicated through the medium of the
gearing to the screws of the back nuts.
The movement apart of the back nuts draws the two ends of the cord which
enters with the leather into the heel part of the groove until, the block screw
having entered the nut as far as possible the block will be keyed on the latter;
if, then, the bevel wheel be moved out of gear, the pin will at the same time
be moved out of engagement with the plate which, with the block and all the
parts carried thereby, can then revolve, the effect of which will be to twist the ends
of the cord. This finally secures the cord and prevents it from becoming
slackened.
It only remains now, in order to complete the operation, to disengage the cord-
carriers from the back nuts after which the lever must be raised to free the nut
socket which will allow the finished boot to be replaced by another boot ready to
be operated upon.

An Improved Machine for the Manufacture of Boots and Shoes.
I, AUGUSTO SANDINO, Director of La Société N. Farina-y Cia., of Corunna,
in the Kingdom of Spain, Manufacturers, 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 a machine for connecting the uppers of boots and shoes
to the soles in the manner described in the Specification of former Letters Patent
granted to me dated 19 August 1889, No. 13072.
In order to enable my invention to be fully understood I will describe it by
reference to the accompanying drawing, in which
Figure 1 is a vertical section of a machine for the manufacture of boots and shoes
constructed according to my invention:
Figure 2 is a vertical section of part of the machine, the section being taken on
the line of Figure 1:
Figure 3 is a horizontal section :
Figures 4 to 6 are detached views of parts of the machine; and,
Figures 7, 8 and 9 are views illustrative of the stages of manufacture.
The machine is constructed of a standard V having four arms arranged in the
form of a cross, the side arins being provided with two bearings and in which
are located the ends of a horizontal screw X, the arm at the rear having a
bearing which receives a hollow threaded shaft or nut S and the front arm
carrying a plate K secured thereto by means of a bolt
junction of the back arm with the three other arms it is
socket in which is loosely fitted a round pin A.
and a pin ". At the
provided with a vertical
When using the machine the sole F, made with a groove all round it, is first
placed upon a false metal sole E, the last F is placed upon the boot-sole and all
three are firmly secured together by means of a screw D and nut B. The last is
provided at its upper part with a metal plate H formed with a recess which prevents
the head of the screw from moving and with a nut in which works a screw G.
The loose portion or instep of the last is manipulated in the usual way by forming
it with a recess to admit the screw G, and the edges of which bear upon the
shoulder of the screw.
I
The last is then covered with the upper-leather which is
carefully stretched at all parts and then secured by sewing the lower edge of the
leather all round to the false sole E, provided along its border for this purpose
with a line of holes the thread is sufficiently tightened for the leather to closely
hold to the last and the leather is still further stretched by the loose portion of
the last being operated upon by the shoulder which is forced up by means of the
screw G. The required curve is, at the same time, given to the sole by causing it to
conform exactly to the shape of the last through the medium of three screws e, e',
operated by a suitable key.
ell
The boot thus prepared is then placed on the machine by passing the socket
which forms the base of the nut B over the head of the pin A and then fixing it
thereto by a bayonet joint formed by three projections a on the pin entering three
corresponding slots formed in the bottom of the socket B.
The lower end of the pin is flattened and embraced by a fork on the end of a
lever C, the head of which consists of two cylindrical portions located in similarly
shaped recesses made in the bottom of the vertical socket V₁, so that the fork Ċ
can freely turn around the horizontal axis common to the head C' and to its
cylindrical bearing.
The two portions of the fork are connected by a bolt c and a screw c; the
bolt c is eccentric and passes into an eye in the end of the pin A. By this
construction if the lever C be pressed down it will cause the base of the socket B
to press tightly upon the top of the socket VI and the boot thus becomes fixed in a

page_text: convenient position for being operated upon in the following manner, safety and
elasticity being ensured by the interposition of a leather washer a¹.
The entry of the upper into the groove at each side of the sole F is ensured by
means of plates and carried by brackets I and jointed at to the plate K
and moved by means of two nuts Y, Y¹ working over a screw X, which nuts guided
by a rody move towards each other when the hand wheel X' is turned in the proper
direction. The leather upper is then similarly forced into the groove at the heel
by means of a plate set in a block or bearing L which is moved forward by the
combined action of a screw N and its nut $ operated by the hand wheel S¹. As
soon as the plates commence to enter the groove the threads which attach the
leather to the false sole E are cut which allows the leather to enter the groove.
The insertion of the leather by the side plates J and J', which penetrate more
deeply into the groove than the heel piate is further facilitated by lowering the
instep, which is effected by lowering the shoulder g, of the screw G.
When the three plates have entered the groove as far as they can go a metallic
or other cord is brought on a level with the groove in the sole it is then passed
over two rollers and and its ends are each threaded through the transverse holej
in the waist of the sole as shewn in Figure 7 the ends are then attached to cord
carriers and Z on the nuts or carriages Y, Y, by passing the cords through a
slit arranged for that purpose. If now the hand wheel X' be turned in the reverse
direction to that which caused the plates to enter the groove, the two ends of the
cord will be simultaneously drawn along and the said cord consequent upon its
passage over the rollers and will, with the leather, enter the portion of the groove
at the toe end of the sole.
l
After the cord and the leather have reached the bottom of the groove at the toe,
as shewn in Figure 7, the hand-wheel X' is slightly turned back so as to slacken
the cord upon the rollers to allow of it being removed therefrom; the movement
of the nuts Y Y away from each other is then continued which causes the cord
and the leather to completely enter the whole of the side portions of the groove
comprised between the toe and the transverse hole (Figure 8). The cord is then
slackened by a slight reverse movement of the hand wheel X which allows of
separating the cord carriers from the nuts Y and Y'; the two ends of the cord are
then brought round the heel and passed over the heel plate so as to allow the cord
carrier to be applied to the nut R', and the thread carrier Z to the nut R
(Figure 3).
The threaded nut S which turns in the bearing under the action of the hand
wheel S has a screw N in its interior and a bevel wheel O on its exterior which
latter, when rotating it rotates by means of a sliding snug. The screw N is
attached to the block or bearing L, L' which is prevented from turning by a pin
and moves in a straight line according to the direction of movement of the wheel S.
This block serves as a bearing for a shaft one end M of which is screw-threaded,
and the other is provided with a shoulder m and a pin m². On the threaded part is
keyed a pinion P and another pinion P is arranged opposite to it and encloses the
shoulder m by means of a plate fixed to the pinion by two screws the said plate
being formed on a sleeve M capable of rotation upon the pin mand screw threaded
on its exterior in the same direction as the shaft M.
The bevel wheel O, which is constantly acted upon by a spring Q is always in
gear with the pinions which project through openings and p in the plate L
which beyond the said openings is provided with two grooves and in which
slide ribs formed upon the two nuts Rand R', which work over the two screws M
and M. These nuts thus guided are forced to recede from each other at the same
time that the heel plate / leaves the groove and the leather, when the hand wheel S
causes the threaded nut S to revolve in the required direction to draw back the
screw N.
This movement is communicated through the medium of the
gearing O, P, P¹ to the screws M and M'.
The movement apart of the nuts R and R' draws the two ends of the cord f
which enters with the leather into the heel part of the groove until the screw N

page_text: having entered the nut S as far as possible the block L will be keyed on the latter;
if then, by means of a pedal lever Û the bevel wheel O be moved out of gear, and
the pin at the same time be withdrawn the block L will revolve together with
the parts which it carries, the effect of which will be to twist the ends of the
cord, which are thereby completely knotted together and are not liable to
become unfastened.
In case the tightening in the groove should not be complete at the moment when
the block is keyed to the nut, it can be done by turning the pinions P and P¹ by
hand before twisting the ends of the cord. Also if the complete tightening were
effected before the keying it would be necessary to ungear immediately, then cause
the screw N to enter until the keying takes place, meanwhile holding the plate L'
by hand to prevent it from turning.
It only remains now, in order to complete the operation, to turn the hand
wheel S in the reverse direction to disengage the cord carriers from the nuts R
and R' after which the lever C must be raised to free the socket 13 which will allow
the finished boot to be replaced by another boot ready to be operated upon.
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. A machine for rapidly fixing the uppers to the soles of boots and shoes
constructed and arranged substantially as herein before described. And in a
machine for rapidly fixing the uppers to the soles of boots and shoes the following
subordinate features mentioned in Claims 2 to 5.
2. The arrangement of plates J and J' suspended and jointed at
and operated
by nuts Y and actuated by the rotation of the hand wheel X and the arrange-
ment of the heel plate I fixed to the block L and operated by the rotation of the
hand wheel S¹.
3. Drawing the metallic or other cord first over the rollers i and by means of
the nuts and Y' and finally by means of the nuts R and R.
4. The arrangement of mechanism consisting principally of the block L. and the
Screws M, M and N for drawing the cord tightly round the heel and subsequently
twisting the same.
5. The frame or standard having arms arranged in the form of a cross for
supporting the whole of the mechanism.
