Improvements in and relating to Machines for Loading Heels
with Nails.
I, ERASTUS WOODWARD, a citizen of the United States of America, residing
at 32 Wigglesworth Street, in the Town of Somerville, County of Middlesex and
State of Massachusetts, one of the United States of America, Mechanical Engineer,
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 certain new and useful improvements in heel loading
machines, in which nails are partly driven into a pile of heel lifts in order to form
a.heel blank ready to be attached by the same nails to the heel seat of the boot
or shoe, and my improvements are adapted for use in machines of the character.
shown in my British Patent, No. 14,487, filed June 30,-1896.
One object of my invention is to provide for the vertical adjustment of the heel
plate and the heel blank located thereon in relation to the nail driving mechanism,
so that the variations in the heights of the heels to be loaded with nails, and the
lengths of the nails to be used, which vary according to the thickness of the heels
to be loaded, can be provided for, and another object is to provide for the
horizontal adjustment of the heel blank on the heel plate in relation to the nail
driving mechanism, so that the position of the nail driven into the heel blauk can
be arranged with reference to its distance from the breast or front edge of the '
heel, and also from the back edge of the heel. A further object is to provide for
the manipulation of the heel plate by drawing the same quickly away from the
machine after a heel has been loaded, removing the same and placing a heel blank
on the heel plate and bringing the heel plate with the first feeding point of a
series of feeding points located thereon quickly into position for the loading of
the heel blanks with nails.
These, and other objects are accomplished by the mechanism hereinafter
described, and shown in the drawings.
My invention consists of certain novel features hereinafter described, and
particularly pointed out in the claims.
In the accompanying drawings which form a part of this application and illustrate
a construction embodying my invention-

In the drawings, A represents part of the frame of a machine of the character
shown in the above-mentioned patent, and secured to the said frame A is a vertical
bracket B, having two horizontal arms B' through which bolts B' pass, and secure
said bracket to the frame A of the machine. (Figures 1 and 8.) Resting against
said fixed bracket B is arranged a vertically movable bracket C, consisting of a
vertical wall C', and two horizontal arms C, and from the vertical portion C¹
extend two webs C for strengthening and supporting the horizontal arms C. The
upward movement of said bracket C is limited by a pin C₁ located thereon, which,
in the upper limit of movement of the bracket C, strikes one of the plates C
which are secured on both sides to the bracket B by screws C, and said plates C
extend over the reduced edges C7 of the vertical wall C¹ of the bracket C and
provide a guide-way for said bracket C on both sides in its upward and downward
movements. The downward movement of said bracket is limited by the lug B',
cast with or otherwise secured to the lower part of the bracket B, and through
an eye in said lug B³ there is arranged a thumb screw B', the upper end of which
bears against the lower portion of the bracket C, and by the movement of said
thumb screw B the said bracket C can be adjusted to the proper height, as may
be required, and for reasons which will be hereinafter explained, (see Figures 1, 8
and 9).
On the top of the arms C2 there is located a sliding plate D, having a depending
lug D extending down in the space between the arms C', and to said lug there is
secured a pin D³, to which one end of the coiled spring D³ is secured, and the other
end of said spring is secured to a suitable pin D fastened to the vertical wall C
of the vertically movable bracket C, and the function of said spring is to retain
said sliding plate D in the positions shown in Figures 4, 5, 6, 7, 8 and 9, that is,
with the inner end of said plate D near the upper part of the vertical wall C¹ of
the bracket C, as shown in Figure 6.
Secured to the side of one of the arms C2 is an adjustable bracket E, (see

page_text: Figure 1), having a vertical portion E', and at its top a pin E, on which is
mounted the friction roller E, and by means of a bolt E' and slot Es the said
bracket can be adjusted horizontally in position on the arm C, and by means of
the pin E, projecting from the side of the arm C into the slot E' of the
bracket E, the said bracket is kept in a straight line in its adjustments.
Secured to and extending upwardly from the sliding plate D is a pin F (see
Figures 7, 8 and 9), on which the hub F of the cam plate F is mounted, and by
means of the plate F and screw-nut F said cam plate by its hub F¹ is retained
on said pin F and adapted to revolve thereon. A recess F is formed in the said
cam plate and fits around the friction roller E' mounted on the pin E of the
bracket E, and said cam plate is also provided with the point F adapted to come
in contact with a recess in the heel plate and hold said heel plate out of an
operative position, as hereinafter described.
Secured to and projecting upwardly from the sliding plate D at the other end
from the cam plate F, is a pin G (Figures 6 and 9), on which the heel plate G'
is mounted and adapted to revolve, and the said heel plate is constructed of an
upper plate G and the lower plate G³, with a series of feeding pins G extending
between said plates G and G. The hub G, which fits over the pin G, (see
Figure 12) extends from the upper plate G, and its lower end passes through
an opening in the lower plate G, as shown in Figures 12 and 13, and by means
of a series of rivets G, one of which passes through each of the feeding pins G*
and are riveted at each end, as shown in Figures 12 and 13, the said plates, pins
and hub are held firmly together.
Through the center of the upper plate G there is a longitudinal recess G, as
shown in Figures 2, 3, 4, 5 and 10, and in the rear part of said recess there is
arranged a plate G' composed of a rear upward extension G8 and two horizontal
arms G, having inwardly inclined edges Go, on which edges there is adapted to
bear a plate G", and through said plate is a screw G adapted to screw said
plate G down on the arms G of the plate G', and thereby hold said plate in a
fixed position, so that by means here described it is obvious that said plate G can
be adjusted in any desired horizontal position with relation to the top plate G' of
the heel plate G¹.
A rim G extends around the outer edge of the upper plate G³ of the heel
plate, and beneath it are located the plate G' and the front plate H, arranged to
slide in said longitudinal recess G, and both said plates G and H have dove-
tailed joints, with that part of the plate G around the recess Go, to hold said
plates in their proper positions in their forward and rearward sliding movements
in said recess G (see Figures 3, 10 and 13).
Secured to the under side of the front end of the plate H is a pin H', to which
is secured one end of a coiled spring H, and the other end of said spring is
secured to the pin H³, extending upwardly from the hub G, and by means of
said spring the cross-plate H, secured to the front plate H, is held in contact
with the front edge of the rim G" (see Figure 12), and the plate H is held in
the position shown in said figure and in other views of the drawings, by means
of said spring.
Located on said cross-plate H is an arm H' (see Figures 12, 13 and 14), having
an eccentric opening Hs, and on one end a vertical lug H, and on the opposite
end a vertical lug Ho with a right angle end H", and located on said arm H' is
another arm H", having an eccentric opening H adapted to register with the
eccentric opening H when said arm H is placed over the arm H', and said
arm H is also provided with an extension H adapted to bear against the rear
side of the lug H, and another arm H" adapted to bear against the rear side
of the lug H and with a right angle end H located around the end of the said
lug H
On the under side of the ring H" are secured two eccentrics, H18 and H", and
through said ring and eccentrics there is a suitable opening through which the
screw His adapted to pass and screw said ring H" and plates H7 and H down

page_text: firmly on the plate H secured to the plate H, with the eccentric H18 in the
eccentric opening H, and the eccentric H" in the eccentric opening H of the
"plates H" and H', respectively. By means. of said eccentrics working in the said
openings it is obvious that by first loosening the screw. H and then taking hold
of the pin H on the ring H; the said eccentrics can be moved and will act at
one and the same time and in opposite directions on the plates H' and. H
respectively, and move the said plates inwardly or outwardly as the eccentrics are
respectively brought toward the ends of the eccentric openings, or against the
sides, as it is obvious that when moved against the sides of said openings the
eccentrics will move said plates outwardly from one another, as said eccentrica
move together and act oppositely on the plates H' and H, but when said ring H
is moved so that the eccentrics are brought toward the ends. of the openings
instead of the sides, the tendency will be to draw said plates inwardly and move
the said ends H and H toward one another, the said inward or outward movements
depending upon the space required between the said ends H" and H to accom-
modate heels of varying width at the breast on the heel plate G¹, for if a heel
wide at the breast is to be loaded; the ring, H is moved to cause the eccentrics
to act on the sides of the openings H and H and thereby move the arms laterally
away from one another so as to increase the space between the right angle
ends Hand H1, or if a heel narrow at the breast is to be loaded, by turning
the 'ring H7 so that the eccentrics. H18 and H move toward the ends of the
openings Hand H8, the ends Hand He can be made to approach one another
to accommodate a heel narrow at the breast, so that by the means here described
it is clear that heels which vary in width at the breast may be placed on. the
same heel plate and loaded, and within ordinary limits, say about one-fourth of
an inch in width at the breast, the. plates H' and H" can be adjusted as above
. described for such. heels, but if the width at the breast should vary greater than
this, the plates H and H can be changed to plates of similar construction but
'of greater or less width, depending upon the width of the heel at the breast to be
loaded. Short pins H (see Figure 1) secured to the plate H* act as
the plates H and H in their lateral movements.
guides for
As shown in Figure 15, to apply a new heel blank to the heel plate, the breast
of the heel is placed between the arms H and H against the lugs H and H
of the arm H', and by pressing slightly forward against the above mentioned parts
the, said plate H, to which the plates H' and H are secured by the screw H
(see Figure 12), moves forward against the tension of the spring H, and the rear
of the heel is moved down into position against the vertical part Gs of the rear
plate G, and the spring. H' contracting, holds said heel firmly between the front
plates H and H and the upper part G of the rear plate G', as shown in
Figure 1, and by the movements above described, that is, the moving forward of
the plate H against the tension of the spring H2 by pressure of the breast of the
heel blank against the parts above described, the rear of the heel can be placed
down on the rim G" of the heel plate past the forward incline of the top GB of the
rear plate G7, and the plate H with the arms H' and H", provided respectively
with the right angled arms H" and H, between which the breast of the heel is
placed, adapt themselves, against the tension of the spring H, to the length of the
beel blank placed on said heel plate after the rear plate G' has been adjusted for
locating the position of the driven nails with reference to the breast and back of
the heel, as hereinafter fully described...
I
Referring now to Figures 8 and 9, there is arranged on the under side of 'the
sliding plate D, the depending lug D, with which the upper end of the lever K
is adapted to come in contact and press the sliding plate D outwardly into the
position shown in Figure 1, against the tension of the spring D. The lever K
extends downwardly and is journaled on, the bolt K' having a support in the
lower end of the arm K, which is provided with a horizontal arm K, secured by
bolts K to the frame of the machine. Beyond the fulcrum K¹ the lever K is
provided with an arm K and suitable vertical connections K', to which is connected

page_text: the pivoted treadle K', provided with a foot rest K, so that by pressing down on the
foot rest K, the upper end of the lever K acts against the lug D³ and moves
the sliding plate D out into the position shown in Figure 1, and as said plate
moves outwardly, the cam plate F' being journaled on the pin F, turns on said pin,
and the anti-friction roller Es, located in the recess F' of the cam plate F³, moves
said cam plate into the position shown in Figure 1, with the point F moving into
the recess G" in the side of the top plate G of the heel plate G', and thus locks
said heel plate in, the position shown in Figures 1 and 2, in which position a
loaded heel can be removed, and a new heel inserted by the attendant.
In Figures 1 and 2 this position of the parts is shown, representing the plate D
held out in the position above described with a new heel on the heel plate and the
heel plate remaining in its locked position until the foot is removed from the
treadle K', when the spring D' draws said plate D back into the position shown in
Figures 3, 8 and 9, with the first feeding pin between the teeth of the feed wheel I,
as shown in Figures 3 and 7, and the cam plate F being journaled on said plate D,
is caused by the inward movement of said plate D, due to the spring D³, and the
friction roller E³, to assume the position shown in Figures 3 and 9.
The object of the adjustable bracket E, previously referred to, is, that if a large
heel plate is to be used, the bracket would be moved as far away from the heel
plate as necessary, and if a small heel plate is to be used, the bracket would be
moved nearer to the said small heel plate, than when a large heel plate is used.
In all cases of adjustment, the principle is the same, namely, that the distance the
bracket to be moved is the distance necessary to allow a free revolution of the heel
plate during the loading of the heel, without contact between said heel plate G
and cam F during such loading. As the heel plates decrease in size, the bracket
is moved nearer to the heel plate, so that when pressure is applied to the treadle
to move the plate D outwardly, the end F of the cam plate F will pass quickly
into the recess G of the heel plate, for if the bracket E was out to the extreme
limit necessary for the largest heel plate, it is obvious that unless said bracket
was moved inwardly for small heel plates, it would require a longer time for the
cam plate F' to engage the recess G of the heel plate, than where said bracket E
is adjusted nearer to said heel plate, for it would take a longer stroke of the foot
to cause the engagement of said cam plate and heel plate.
It is evident that as the slide D moves outwardly, the cam F' begins to revolve
toward the heel plate, and the end F' of the cam F strikes against the point G15
of the upper plate G' of the heel plate, and by striking said point it revolves said
plate around until the are or recess G" of the plate will just fit the arc of the cam,
as shown in Figures 1 and 2, and thereby lock said plate to receive a new heel,
and in this position the first feeding pin G of the heel plate is in a horizontal line
with the teeth of the ratchet wheel and the lug Cs, as indicated by line 3-3,
Figures 1 and 2, so that as the heel moves inwardly by reason of the spring D³,
the first feeding pin will pass into proper position with the feed wheel I and over
the lug C, and thus said cam plate F serves not only, in connection with the
recess G, to lock said heel plate in position to allow the removal of a loaded
heel and the insertion of a new heel blank to be loaded, but also is the means by
which the first feeding pin of the heel plate is arranged in a horizontal line with
the feed wheel I, so that said first pin will pass into its proper position with said
feed wheel as the heel plate moves inwardly after a new heel has been placed
thereon to be loaded with nails.
From the above it is clear that the first feeding pin G is so located by the cam
plate as to engage with the feeding mechanism upon the engagement of the
beel plate and feeding mechanism before any other pin of said series, so that by
providing mechanism which causes the first feeding pin G' to come under the nail
driving mechanism before any other pin of said series, it is evident that a nail will
be driven into the heel blank for every feeding pin on the heel. plate from the first
to the last, or, in other words, that there will be as many nails driven into the heel
blank as there are feeding pins on said heel plate.

page_text: The feed wheel I and the ratchet wheel 13, secured to the under side of said foed
wheel I, are both mounted on the shaft I', located in the frame A. of the machine,
and said ratchet wheel may be driven by any suitable operating mechanism to
communicate power to the said feed wheel 1, by which said heel plate G¹ is
operated.
At the top of the vertically movable bracket C, and between the two horizontal
arms C, there is arranged a short pin or lug C, which lies just below the wheel I,
and between the teeth thereof, see Figures 1, 6 and 7.
When a new heel has been inserted on the heel plate G and pressure is removed
from the treadle, the spring D, acting on the plate D, moves said heel plate
inwardly to an inner position, so that the first of the feeding pins G passes between
two of the teeth of the feed wheel I, see Figures 3 and 7, and directly over the
lug C. Now as the feed wheel I is mounted on a fixed shaft, and consequently
has always the same horizontal relation to the lug C, it is obvious that as the feed
wheel is turned and a new pin G' comes into the space between the teeth of the
revolving wheel I, each pin is located over the lug C, so that said lug takes up the
blow of the driving mechanism, as the nails are driven into the heel by any suitable
driving mechanism, as X, shown in dotted lines, Figures 1 and 7, whose line of
vertical movement, in 'relation to the lug C and each pin moved over said lug, is
indicated in Figure 1, and by line 1-2, Figure 7. As the hub G' is mounted on
the pin G and adapted to revolve thereon, it is obvious that as the pins G are not
all located at points equally distant from the hub G as a center, each pin G in the
revolution of the heel plate passes into a depression between the teeth of the feed
wheel I, and as said feed wheel is fixed on a center and cannot yield, the plate D
must have a slight inward and outward movement under the control of the
spring D as the various pins come into position between the teeth of the feed
wheel I, and said springs tends to hold the pins in contact with said feed wheel I,
but allows an inward and outward movement to the plate D, owing to said pins, as
previously stated, being, not all located at points equally distant from the hub G
as a center, consequently said plate D is adapted to move slightly inward and
outward as the various pins are brought into relation with the feed wheel I. In said
revolution of the heel plate, each pin comes over the lug C, and as the last one of
the feeding pins G moves around into position between the teeth of the feed
wheel I and over the lug C, the heel plate assumes the position shown in Figure 4,
and an extended corner G comes in contact with the knob L, secured to the free
end of the arm L', which extends to and is connected with any suitable power
shifting mechanism, and as the wheel continues its movement, the said corner G
moves said knob away from its position shown in Figure 1, and the power is thrown
off. Any power shifting mechanism may be used, it being only necessary that
some means should be provided on the heel plate to trip off the power when the last
nail has been driven, and as the said last nail is driven and the power has been
thrown off, the heel plate assumes the position shown in Figure 5, with the naila
driven into the heel corresponding in number and in position to the number of
pins Gon said heel plate, so that it is obvious that a greater or less number of
nails may be driven, as desired, depending upon the construction of the heel plate,
which may vary, suitable for large or small heels and for greater or less number of
nails to bo driven into the heel. When the heel plate assumes a position shown in
Figure 5, the operator presses on the treadle and throws the heel plate out into the
position shown in Figure 1, when the loaded heel can be removed and a new one
inserted in its place, and the operation continues as above described, the power
being put on by pressure of the foot on a suitable treadle connected with the power
shifting operating mechanism, as the first feeding pin of the heel plate passes into
operative position with the feed wheel I.
From the above description it is obvious that as many nails will be driven into
the heel blank as there are feeding pins G, and that the position of each nail
driven into the heel is determined by the position of said feeding pins, that is, each
nail is driven into the heel directly above one of the said feeding pins, for as each

page_text: feeding pin in turn comes over the lug C³, a driving operation takes place, and as
the lug C is in the same vertical plane as the line of motion of the nail driving
mechanism, it is evident that the position of each nail driven into the heel blank is
directly above one of the feeding pins G. As shown in Figure 1, in full lines,
and in Figure 2 in dotted lines, a new heel blank has been applied to the heel
plate before the same has moved into position to be fed by the feed wheel and
to be loaded with nails, and in Figure 3 the heel plate has moved, by reason of the
spring D, into the position shown, with its first feeding pin in proper position
with the feed wheel, by which the heel plate is operated, and in Figure 4 the heel
plate is shown as having been turned by the feed wheel from the position shown in
Figure 3 until the last feeding pin has moved into position with the feed wheel,
and as shown in dotted lines, there has been driven into the heel blank nails M,
one above each feeding pin G, shown in dotted lines, and as the last nail is driven
above the last feeding pin, the heel plate assumes the position shown in Figure 5,
in which there is shown in dotted lines a heel blank with the nails M also in dotted
lines, one above each feeding pin G shown in dotted lines, and in this position, as
previously described, the operator pressing on the foot rest K³ of the treadle K',
moves the heel plate out into position shown in Figure 1, when the loaded heel
can be removed and a new heel blank inserted to be loaded by the next operation.
As the feeding pins Gare in a fixed position in reference to the pin G, on which
the heel plate revolves, it is evident that by changing the position of the heel blank
in reference to the said pin G as a center, the position of the nails driven into the
heel blank in reference to the breast of the beel or back will be changed, for if the
heel be moved forwardly against the arms H' and H", it is obvious that the driven
nails will be some distance back from the breast of the heel, and nearer the back
edge of the heel, or if the heel be located back so that the breast of the heel is
just slightly beyond the front pins G, the nails driven will be nearer the breast
of the heel and away from the back edge of the heel, as shown in Figure 16 and
also in several of the views where the heel and driven nails are indicated in dotted
lines, and in some cases this is desirable in order that the back of the heel may
be concaved, in a style known as the French heel. Now, in such a case, if the
nails were driven away from the breast and near the back edge of the heel, in
shaping the heel by the cutter after the attachment of the heel to the boot or
shoe, the cutter would cut into said nails and destroy the heel, so that by those
manufacturers who desire to concave the heels, it is necessary to drive the nails as
near to the breast of the heel as is possible, and away from the back. In order to
accomplish this desired position of the nails in the heel blank, all that is necessary
is to adjust the back plate G', for if the said plate is moved inwardly toward the
front plates H' and H", it is obvious that the breast of the heel will be located a
considerable distance forward beyond the line of the two front feeding pins G',
and the nails will be located away from the breast and near to the back edge of
the heel, and in such case of course the heel could not be concaved, but where it
is desired to concave the heel, the plate G' is moved outwardly away from
plates H' and H", as indicated in Figures 4 and 5, so that the breast of the heel is
just slightly beyond the two front pins G, in which case the front nails are near
the breast of the heel and the other nails do not approach the back edge of the
heel, as they would where the front or breast nails are driven farther away from
the breast of the heel, so that it will be seen that the adjustment of the back
plate G' determines the distance the breast nails are located from the breast of the
heel, so that the nearer to the breast of the heel the breast nails are located, the
farther distance the other nails are from the back edge of the heel, and vice versa,
the farther away from the breast the breast nails are located, the nearer the back
of the heel the other nails are located, and it will be noted that in all cases the two
front pins G'determine the position of the two front or breast nails in the heel blank.
By this construction the nails can be located in any desired position in reference to
the back edge of the heel, or breast of the heel, depending upon the shape it is
desired to make the heel, and in this way each manufacturer can decide for himself as

page_text: to the positions the nails will occupy. The heels are always adjusted from the back
with relation to the curve of the heel seat of the boot or shoe, the reason being
that a jack is provided on which the shoe is placed, and the nails must all be in the
same relation to the back of the heel, in order to have the heel come in the right
position upon the curve of the heel seat of the boot or shoe, and the front of the
heel is movably adjustable because it is immaterial how far front the breast of the
heel comes, but it is evident that the back edge of the heel must always have a
fixed adjustment because it must always come in line with the curved edge of the
heel seat of the boot or shoe. The upper surface of the heel blank, into which the
nails are driven, must of course always extend beyond the position of the feeding
pins Gin order that the nails be driven into said heel blank, and it is immaterial
how much concave there is to the heel blank when placed on the machine to be
loaded, as the yielding front plates H' and H" and adjustable back plate G' can
be set so as to locate the breast nails near the breast of the heel and the other
nails away from the back edge of the heel blank, and it is only necessary that the
upper surface to receive the nails shall extend over, or, in other words, have its
surface above each feeding pin, so that the nail can be driven therein, as each
feeding pin comes over the lug C" and in the line of motion of the nail driving
mechanism. As previously stated, in some cases where the front plates H' and H
cannot be moved a sufficient distance laterally to accommodate a heel very wide at
the breast, new plates H' and H" of greater width can be substituted for the
shorter ones; so also, in cases where the heel is long, or that part of the heel
which rests on the heel plate is very long, if the back plate is too short to be
properly adjusted to accommodate such a heel blank, to locate the breast nails
forward and the other nails away from the back of the heel in order to make a
French heel, then in such cases a back plate G³ of greater length can be
substituted.
As heel blanks of different heights or thicknesses may be used on the same
machine, it is of course necessary to vary the length of the nails used for loading
said heel blanks, and as the nail must be driven just through the heel lifta forming
the heel blank, it is obvious that where a long nail is used for a heel of greater
thickness, the bracket C must be adjusted downwardly in relation to the nail
driving mechanism, because said nail driving mechanism always strikes said nail at
a fixed point and has always a certain limit of stroke, so that the nails, when driven
will just pass through the heel lifts, as shown in Figure 16.
Now in the case of thin heels, short nails are used, in which case the vertically
adjustable bracket C must be moved upwardly in order that the nail driving
mechanism, which, as above stated, always strikes said nail at a fixed point, and
has a certain limit of stroke, will drive said nails just through the heel lifts forming
the heel blank, so that the object of the vertically adjustable bracket C is to adapt
the machine to different thicknesses of heels and to different lengths of nails, which
vary according to the thicknesses of the heels to be loaded on the machine.
As shown in Figure 16, the nails M driven into the heel blank J just extend
through the heel lifts forming the heel blank and leave a certain amount of the
nail above the heel, and the said heel is afterwards attached to the heel seat of the
boot or shoe by any suitable heel attaching mechanism.
