Year: 1884

page_text: I WILLIAM ROBERT LAKE, of the firm of Haseltine, Lake and Co Patent Agents
Southampton Buildings in the County of Middlesex do hereby declare the nature
of said invention for "IMPROVEMENTS IN MACHINES FOR FEEDING AND DRIVING
TACKS IN THE MANUFACTURE OF BOOTS OR SHOES" to be as follows :-
The object of this invention is to provide a light, easily operated, and adjustable
tack-driving mechanism which can be readily moved, and placed easily by one hand
located in relation to a jack or last to be conveniently used during the act of:
bringing up and turning over successive sections of the edge of the upper upon the
inner sole of the boot or shoe.
In machines of this character it is very essential, First that the tack be driven
automatically, Second: that the tack feeding and driving devices be so light and
so supported that they can be easily moved and placed by one band: and Third:
that the tack-driving mechanism have universal, or very nearly universal, adjustment
in relation to the last or jack for supporting the same.
In carrying this invention into practice I provide a standard to which the
operative parts are attached; a post extends upward from the standard and has at
its upper end a bracket; said bracket supports a pintle which is held in place by a
set-screw. Upon this upright pintle I place a swinging yoke. At the outer end
of this swinging yoke I place a second pintle which is steadied in its place by a
supplemental yoke. At the upper end of this second pintle I pivot two lovers, one
of which has a spring which serves to draw its rear end down, and its forward end
upward, the other lever is provided with a spring attached to a vertical rod; this
serves to draw the lever upward; a link is attached to this lever and to a foot
lever so that by depressing the latter the second lever is drawn downward, taking
with it, after a limited motion, the first lever. The tack-feeding mechanism is
attached to the forward end of the latter lever. This mechanism comprises a
sliding piece having notches which engage with the tacks immediately under their
•

page_text: heads and force then along so that at each complete motion of the machine, one of
the tacks is delivered to a nozzle. A pivotted lever serves to cause the feeding
mechanism to operate.
In order to prevent the feeding mechanism from acting except when the
operator has caused the feeding and driving apparatus to make a full and completo
stroke, I bave placed a switch movement in one of the levers and which I will now
describe.
-
A switch-piece, is attached to a T-shaped piece which has a limited motion
around a pivot.
The upper end of one lever has a horizontal projection.
As one of the two first named levers approaches the other lever of the two, a
projection of a lever will glide on the front of the switch, the lower end having no
forward motion, unless the switch descends sufficiently;-which will only take-place.
at a full stroke to allow the projection of the lever to pass over the upper end of
the switch, in which case, in the upward movement of the lever; the projection
will be acted upon by a slide in the rear of the switch. This will throw the lower
end of the lever forward and thus cause the feed-slide to move the tack forward to
the nozzle.
The tack-driving mechanism comprises a driver which is operated by the lever
which communicates its motion by a link. This driver works in a vertical tube
attached to one of the levers.
A handle is attached to the last named lever by means of which the operator can
move the entire tack feeding and driving dovice into any desired position for
operating upon any section of the upper, to be tacked.
The last and shoe are held by an adjustable jack said jack swivelling horizontally
in a swivel and vertically about a pin which is supported by a bracket-arm
attached to the standard, the vertical position of this jack, being determined by a
pinch-bolt and slot.
In operation, the upper and inner-sole having been placed upon the last the
operator with his pincers draws a section upon the last, and folds its edge upon the
surface of the inner sole. He then with one hand holds the drawn-in section to
the inner-sole, and with the other moves the tack-driving devices over the folded-
in margin, and with the foot drives the tack, or causes it to be driven; the tack-
driving device is then moved and another tack driven; and as many are thus
placed as may be necessary to secure that section. The operator then takes
another section of the upper, draws it up, and treats it in the same manner.

page_text: I, WILLIAM ROBERT LAKE, of the firm of Haseltine, Lake, and Co, Patent
Agents, Southampton Buildings, in the County of Middlesex, do hereby declare
the nature of my invention for "IMPROVEMENTS IN MACHINES FOR FEEDING AND
DRIVING TACKS IN THE MANUFACTURE OF BOOTS OR SHOES" and in what manner
the same is to be performed, to be particularly described and ascertained in and by
the following statement:--
This invention relates to machines for feeding and driving tacks in the
manufacture of boots or shoes.
In machines of this class it is very essential, first, that the tacks should be fed
and driven automatically; secondly that the tack feeding and driving mechanism
should be so light and so supported that it can be easily moved by one hand into
and out of its working position; and thirdly, that the tack-driving mechanism
should be capable of universal or very nearly universal adjustment in rolation to
the last or shoe-jack.
The object of the present invention is to provide light, easily-operated and
adjustable mechanism, which can be readily moved by one hand (whilst a drawn-
over section of the edge of the upper is held upon the inner-sole by the other
hand), either into position in relation to the shoe-jack or last to be conveniently
used for driving the tacks for securing the said section, or away from this position,
and which mechanism will feed the tucks, as required, into position for driving.
In the accompanying drawing.

Figure 2 is a perspective view of a series of tacks cut from the said strip by
cutting dies.
Figure 3 is a section of a griping die or device through which the tack-strip is
passed to form the heads of the tacks.
Figure 4 is a perspective view of a series of tacks as it appears after being passed
through the said griping die or head-forming device.
Figure 5 is a side elevation, showing the working parts of the improved
machine.
Figure 6 is a plan, partly in section, shewing part of a tack-feeding device herein-
after described, and
Figure 7 is a perspective view shewing details of what I term a switch-
movement hereinafter described, which operates in connection with the said
feeding device.
:
E indicates the standard of the machine, which carries or supports the operative
parts. El is a post, which extends upward from the standard E and has at its
upper end a bracket E. This bracket supports the pintle K³, which is held in
place by the set-screw c. Upon the pintle K³ I place a swinging yoke K*; at the
outer end of this yoke I arrange a second pintle K which is steadied in position
by the supplemental yoke K³. At the upper end of this pintle K² I pivot at K.
the levers K¹ and L. The lever K¹ is acted upon by a spring M, which tends to
draw its.rear end downward and its forward end upward. The lever L is acted
upon by a spring H³ attached to the vertical rod H, which spring tends to draw
the lever L upward. H' is a rod or link attached at H2 to the lever L and at H*
to the trendle or foot-lever H, so that, by depressing the latter, the lever L is
drawn downward and with it, after a limited motion, the lever K¹.
The tack-feeding mechanism is attached to the forward end of the lever K³,
This mechanism comprises a sliding piece N, N¹ (see Figures 5 and 6), which has
notches n (Figure 6), so that it will engage with the tacks immediately under their
beads, When this sliding piece is moved as hereinafter explained, it forces the

page_text: tacks along in such a manner that, at each complete movement of the machine, one
of the said tacks is delivered to the nozzle P10, Figure 5. In this figure, the tack-
strip is marked P. In Figures 5 and 6, N' is a lever pivotted at N³ and arranged
to operate the sliding piece N, N¹.
To prevent the action of the feeding mechanism except when the operator causes
the feeding and driving apparatus to make a full or complete stroke, I provide the
lever L' with the switch-movement shewn in detail in Figure 7, which I will now
proceed to describe.
P is a switch attached to the T-shaped piece P³, which has a limited notion
around the pivot P1, and is acted upon by a spring P8. The upper end of the
lever N has a horizontal projection N, Figure 7. As the lever L approaches the
lever K, the projection Nº of the lever N2 slides along the front of the switch P,
the lower end of the lever N₁ and the sliding piece N, N' are thus moved back-
ward; but the lower end of the lever N' has no forward motion imparted to it,
unless the switch P descends sufficiently to allow the projection N³ of the lever N
to pass over the upper end of the said switch (which will only take place when the
feeding and driving apparatus makes a full or complete stroke), in which case, in
the upward movement of the lever L, the projection No will be acted upon by the
inclined face P7 on the rear of the switch P. This action. will throw the lower end
of the lever N° forward and thus cause the feed-slide N, N' to move the tack-strip
forward towards the nozzle P¹º
The tack-driving mechanism comprises a driver L³ operated by the lever L, from
which motion is communicated to the said driver by a link L. This driver L'
works in a vertical tube Kª attached to the lever K.
K' is a handle which is attached to the lever K' and whereby the operator can
move the entire tack feeding and driving mechanism into any desired position for
operating upon any section of the upper to be tacked.
The last and the boot or shoe F are held or supported by an adjustable shoe-
jack F. This shoe-jack is capable of swivelling in the socket or bracket F²; it is
also capable of adjustinent in a vertical plane around the pin or stud F, which is
supported by a bracket Es attached to the standard E. The said shoe-jack
is secured in the desired position in the said vertical plane by the set-screw F,
which is passed through the slot F³ and screwed into the bracket E³.
The operation of the machine is as follows, that is to say, the upper and inner-
sole having been placed upon the last, the operator, with his pincers, draws a
section of the upper over the last, and folds its edge upon the surface of the inner-
sole, he then, with one hand, holds the drawn-over section upon the inner-sole, and,
with the other hand, moves the tack-driving devices over the folded-in edge or
anargin, and, with his foot, operates the said devices and drives the tack or causes
it to be driven. The tack-driving devices are then moved into a fresh position and
another tack is driven; as many tacks are thus driven as may bo necessary to
secure the said section of the upper. The operator then takes another section of
the upper, draws it over and treats it in the same manner, and so on until the
upper is properly secured to the inner-solc.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is :-
First. The combination, with a shoe-jack, of tack feeding and driving mechanism
carried by an arm or lever pivotted to a movable support and adapted to be moved
by one hand into, and out of or away from, its working position, substantially as,
and for the purpose, set forth.
Second. The combination, with the tack-driving mechanism, of the pivotted arın
or lever K¹ and the handle K', substantially as, and for the purpose, set forth.
Third. The combination of the shoe-jack, the tack-driving devices carried by
the movable arm or lever, and a treadle connected with the said arm or lever, for
operating the said tack-driving devices, substantially as, and for the purpose, set
forth.

page_text: Fourth. The combination of a shoe-jack, tack feeding and driving devices and a
treadle or other suitable means for moving the said devices vertically in relation to
the work, and for holding the nozzle of the tack-driving device in contact with the
work during the driving of the tack, substantially as, and for the purpose, set
forth.
Fifth. The above described improvement in lasting boots or shoes, which consists
in adjusting the upper and inner-solo upon the last, drawing the upper over tho
edge of the inner-sole, holding, with one hand, the part of the upper thus drawn
over, placing, by the other hand, the tack feeding and driving mechanism upon
that section of the upper thus held, and then driving the fastening, all substantially
as, and for the purpose, set forth.
Sixth. The combination of tack feeding and driving mechanism capable of being
easily placed by one hand upon any part of the upper of a boot or shoe after that
part has been drawn over the inner-sole, and a shoe-jack capable of rotary notion
in a horizontal, or nearly horizontal, plane, substantially as, and for the purpose,
set forth.
Seventh. The improved machine consisting of the parts constructed and
combined substantially as described with reference to the accompanying drawing
and operating as, and for the purpose, set forth,
