Improvements in and relating to Machinery for Uniting a Welt or
Rand to a Sole or Heel of a Boot or Shoe.
A communication from abroad by MCKAY SHOE MACHINERY COMPANY, of 76,
Lincoln Street, Boston, in the State of Massachusetts, one of the United
States of America.
I, ALFRED GEORGE BROOKES, of 55/56, Chancery Lane, in the County of London,
Chartered Patent Agent, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
In this machine a sole or heel to receive a welt or rand is laid on a spring sup-
ported table which is rotated intermittingly by a long vertical pinion, so that the
table may occupy any position required to adapt it to the thickness of the sole
or heel.
The welt or rand being applied to the sole or heel is acted upon by a feeding
device shown as a wheel, which has a surface speed a little faster than the surface
speed of the table so that the tendency of the feeding device is to crowd the welt
forward to thus enable said welt to be fed, as it were, a little faster than the sole
in order that it may be crimped and laid on the sole in the outline of the sole.
The welt is controlled by a welt feeding guide composed of a bottom plate on
which the underside of the welt rests, and a pressure finger acting on the top
or upper side of the welt, said pressure finger having teeth which enter the top
side of the welt.
The welt guide is moved back and forth, or toward and from the driver, as
herein shown, in a horizontal circle, it riding backward over the welt or rand after
each nail has been driven into the welt or rand, and at such time the teeth of the
lever scrape over the top of the welt or rand, but just before another nail is driven
the welt guide is moved horizontally in the opposite direction, the teeth of the lever
then entering the welt or rand thus feeding or crowding it toward an edge gauge
and the last nail which was driven, such action enabling the welt or rand to be put
onto the sole or heel without objectionable tension and enabling it to be bent as
required to the curved outline of the sole or heel.
The welt guide is moved away from the nailing point by swinging motion of the
hub in which is mounted the strip carrier, and it has given to it its feeding move-
ment by a suitable spring.

improvements added to enable the invention to be understood;

The stand A' adapted to be supported on the floor, sustaining a head A in which
is mounted a main shaft A provided with the fixed member of a friction clutch
pulley the continuously driven loose pulley mounted on-said shaft alongside of
said fast pulley and adapted to be moved into engagement with the fast pulley on
said shaft by a suitable wedge controlled by a bar 48; the pinion B4 fast on said
shaft A and engaging a pinion 135, fast on a cam shaft 136 having two cams Bī
and B8; the hub C2 of an arm C¹ depending from a hub C; a lever C connected by
a pin-and-slot connection with the said hub C, said lever having a roller or other
stud to enter a groove in the cam 138, to thereby reciprocate the hub C2, the
lever C3 having its hub mounted on the shaft.A and having at its upper end a
Foller or other stud entering a cam groove in the cam hub B, the lower end of said
lever having sector teeth which engage the teeth of a circular block of strip
carrier adapted to be moved back and forth by said lever C3, in said hub C3; and
the lever provided at its lower end with a cutter to co-operate with the usual
stationary cutter, to separate the metallic strip S into nails, are and may be all as
usual in machines of this class.
This strip S is of a width equal to the length of nail desired, and the thickness
is equal to the thickness of the nail desired, and the strip carrier is turned in one
and then in the other direction, to revolve the strip and place first one edge and
then the other edge upwardly, so that the nails cut therefrom by the usual cutting
mechanism will be tapered in one direction, and of uniform thickness in the other
direction.
This nail strip is old, and in common use, and by turning it, it is possible to
always place the nails under the driver b carried by the driver bar B₁ with their
heads uppermost and their points in their correct relative positions. To this well
known form of machine certain parts have been added which I will now describe.
There is provided a stand a of irregular shape secured by a bolt a¹ to an
adjustable block a confined to the standard.
.
This stand has bearings a³, for a rod at, surrounded by a spiral spring a one
end of which is seated on one of the said bearings, while its opposite end acts on
a shoulder a and lifts said rod with its attached work support or table a, provided
preferably on its upper side with a series of sole engaging teeth a', and at its edge
with gear teeth a³.
The rod at, in practice, has its lower end connected with a treadle, not shown,
located at the floor, so that when desired the operator may depress the work support
for the introduction or removal of the work, the depression of the work support
for this purpose drawing down the rod a and lifting the pressing finger b* of the
welt guide from the welt, and above the bottom part 1 of said guide.
The teeth are engaged by the teeth of the long pinion 62, mounted in a tubular
part 3 of the stand a, the upper end of the said long pinion having bevel teeth 64,
which are engaged by the bevel teeth 65, fast on a feeding device or wheel 66,
having preferably a series of teeth b to act on the welt or rand w lying on the
sole wc, or it might be a heel, not shown.
The work support is adapted to rise and fall to adapt it to any variations in
thickness of the sole and welt or rand, or of a heel, and the use of this long pinion
enables the work support to be rotated intermittingly no matter what the thickness
of the material lying on the work support under the feeding device or usual nose
of the machine through which each nail or fastener is driven.
The feed wheel is fixed on a shaft c mounted in bearings of the stand a.
The shaft has a threaded portion c² on which is screwed a ratchet wheel c³,
which is adapted to be engaged, when said shaft is to be moved, by a pawl e,
pivotted on a pawl carrier having a sleeve like hub c, which surrounds the
shaft c loosely, the said sleeve being toothed externally, see Fig. 6, said teeth being
engaged by a toothed rack c fast on the hub C2 and extended under the said sleeve,
see Figs. 1 and 2.
The stand a has an ear d'in which is sustained a vertical stud shown in

page_text: Fig. 6 as a screw, said stud entering a hub of the welt guide frame d², the
stud constituting a vertical shaft for the said frame d².
The frame has a projecting portion 6 which constitutes the lower arm of the
welt or rand guide, said arm supporting the said welt or rand.
The frame has ears d³, provided with a pin d, on which is mounted a sleeve
or tube d³, carrying at one end the welt pressing finger b, having inclined teeth 620,
see Fig. 3, to enter the upper side of the welt or rand.
The opposite end of said sleeve has an arm or extension do provided with a hole
through which the rod a is passed, it having at its upper end a head to act
on the said arm, the said arm having a second projection, which is acted upon
by a suitable spring ds which normally acts to keep the pressing finger 6 down on
the welt or rand lying on the bottom plate 6' and the teeth 620 entering the welt or
rand.
The frame d² has a projection e, acted upon by a spring e¹ which normally acts
to swing the said franie about the stud and keep the bottom plate 61 of the
welt guide against the edge gauge e, connected by screw e3 with the stand a,
said edge gauge also acting as a shield to cover the long teeth of the pinion 62,
the said frame having a stud screw et, which is struck by the hub C2 each time that
the arm C and the hub C2 are swung about the shaft A7.
When the hub C2 meets the end of said stud screw the welt or rand guide is
moved back away from the driver, the teeth 620 then dragging over the welt or
rand, and as the hub C2 is returned or moved away from the said stud screw,
the spring e acts to move the welt guide toward the driver, the teeth 620 at such
times entering the top of the welt or rand and acting on the same to push the
outer edge of said welt or rand against the edge gauge, and to crowd it up toward
the last nail driven into the welt or rand to unite it to the sole or heel.
In this way the welt or rand may be put onto the sole, and so laid as to conform
to any curvature of the edge of the sole, and any unusual stretch in the welt or
rand is also taken out.
The surface speed of the feeding device is a little faster than the surface speed
of the work-support, so that the action of the feeding device on the welt or rand
tends to crowd or feed it up against the said edge gauge and the point where the
last nail is driven into the welt or rand.
The teeth a' by engaging the sole or heel prevent undue slipping of the sole
or heel on the work support.
By the term "welt," as referred to in the claim, I also intend to include its
equivalent, a rand, and by the term "sole," I mean also to include a heel.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, I declare that what. I
claim is:
In a machine for use in uniting a welt or rand to a sole or heel of a boot or
shoe by means of nails or the like:-
1. A vertically movable, loosely supported table to sustain the work; a toothed
gear located below said, table and operatively connected therewith; a long toothed
pinion occupying a position substantially parallel to the centre of rotation of said
table; means to rotate said long toothed pinion that it may rotate said table in
unison with it and yet let said table rise and fall to adapt itself to any variation of
thickness of the material lying upon it and between it and the feeding device
employed to move the material over the surface of said table, substantially as
described.
2. The use with a spring sustained work support having an attached gear, and
a long pinion having its teeth in engagement with the teeth of the said work
support and provided with bevel teeth at one end; of a feeding wheel having bevel
teeth engaging the bevel teeth of the said long pinion, and a shaft, and means to
rotate it, the said feed wheel and the said work support, substantially as described.
3. The use with a strip carrying hub, and its attached rack, and a feed wheel

page_text: and its shaft, of a pawl and a pawl carrier to actuate it, the said pawl carrier being
moved by the said rack, substantially as described.
4. The use with a spring sustained work support, a gear carried thereby and
located below said support, and a feeding device to act upon the material lying
on said table of a long pinion parallel to the shaft carrying said work support,
and gearing between the shaft carrying said feed device and said long pinion,
to rotate said long pinion and cause it to rotate said work-support
whatever its position due to variations in the thickness of the material lying.on
said support and between it and the said feeding device, substantially as described.
5. The use with a driver bar and driver to drive a nail, and a work-support on
which the work to be nailed rests, of a welt guide having a bottom plate on which
the welt rests, a pressing finger resting on the top of the welt, and means to move
the said finger away from said bottom plate, to enable a welt to be laid on said
bottom plate, substantially as described.
on
6. The use with a driver bar and driver to drive a nail, and a work supportl
which the work to be nailed rests, of a welt guide having a bottom plate on which
the welt rests, a finger resting on the top of the welt, means to keep said fin
pressed uniformly on said welt, and means to swing said welt guide toward
from the driver, substantially as described.
d
7. The use with a driver bar and driver to drive a nail, and a work support on
which the work to be nailed rests, of a welt guide having a bottom plate on which
the welt rests, a pressing finger having a pin or tooth to enter the upper side of
the welt, and means to move the said finger toward and from said bottom plate,
substantially as described.
8. The use with a driver bar and driver, a vertically yielding work support to
sustain a sole and adapt itself to variations in the thickness of said sole, and means
to positively rotate said work support in its varying position of a rotatable feed-
ing wheel occupying a fixed position and acting on a welt lying on said sole
and means to rotate said feed wheel positively at a faster surface speed than the
surface speed of said work-support, whereby said feed wheel is enabled to crimp
the welt and lay it. on the curved portions of the sole preparatory to the action of
the driver in driving a fastening into said welt to secure it to said sole, substan-
tially as described.
9. The use with a driver bar and driver, a vertically yielding work-support, and
a welt guide composed of a frame mounted on a vertical pivot and presenting a
bottom plate, of a spring-pressed finger provided with teeth, to engage the upper
side of said welt, and means to vibrate said frame about said pivot to aid in feeding
said welt, and a feeding device acting on the welt being laid and nailed on the
material sustained on said work support, substantially as described.
10. The use with a driver bar and driver, and a vertically yielding movable
work-support to sustain the material, of a welt guide composed of a plate and a
movable finger between which the. welt is laid, an edge gauge, a feeding device
acting on the welt where it contacts with the material lying on the said work-
support, and means to move said welt guide in the arc of a circle, toward and
from the said edge, to force the edge of the welt against the edge gauge pre-
paratory to driving a mail in the welt, substantially as described..
