page_text: is an improvement on Letters Patent of the United States

page_text: Figures 14 and 15 are details illustrating the position of some of the parts at the
end of the upward stroke.
Figure 16 is a sectional diagram enlarged, the full lines indicating the relation
of the heel block and mould before the heel is compressed, and dotted lines after the
heel is compressed.
Figure 17 is a sectional view showing the heel block with a driver (from the driver
block) adapted to tip the nail in position to drive the nail which rests in a perforation
in the block.
The frame A supports the driving shaft a. The driving shaft a is geared to the
main shaft al. This shaft a' moves the block a² up and down once for each revolution
of the main shaft a¹. The motion of the main shaft a¹ and block a² imparts motion to
other parts of the machine only when the block a³ is thrown forward between the
block a² and plunger a, as will be clear without further description.
The first part of the upward motion of the plunger a¹ forces a gang of drivers
against a set of nails, and causes the nails to penetrate the heel and also causes the
breasting knife to breast the heel, and the latter part of the upward motion of the
plunger a powerfully compresses the heel which is held above by the double jointed
arm B, below by the heel block d, at the back and sides by the mould D and at the
breast by the breasting knife F.
The plunger a¹ is adjustably connected with a plunger a' and to the upper end of
the plunger a is secured the plate a upon which the ends of the drivers rest; this
plate as also carries the breasting knife F.
The heel block d is supported by two legs, shown in Figure 3 upon a spline G.
This spline rests upon cross-piece a of the frame. The heel is placed in the mould D
and upon the heel block d, and the shoe is then put in place, if the heel is to be
attached to the shoe.
The double jointed arm B is then swung into place and its toggle-joint straightened
so as to clamp the heel firmly between the shoe 6 of the double jointed arm B, and the
heel block d.
It will be clear from figures 4 and 5, and from figure 2, that by means of the
handles and 62, the arm B can be swung into place as heretofore; but by means of
the toggle joint in the double jointed arm B the heel can be compressed and very
firmly held between the shoe b and the heel block d. This extra joint in the arm B is
an important feature of my invention, as by means of it, I am enabled to secure the heel
much more perfectly than heretofore.
After the heel has thus been secured in the vice b d, the block a³ is thrown into
place (by means of the treadle 1, and lever 2) so that when block a² rises, it carries
with it the plungers a³, a³ and the upward motion of plunger a carries with it the
driver plate a, and the breasting knife F for the driver plate a is held to
the top of the plunger a' by means of a tang and set
Figure 2.
screw as shown in
The nails rest in perforations in the heel block d, (see Figures 6 and 17) and the
drivers extend up from the driver plate a through the perforations in the heel block d.
The plungers a³ and a are so adjusted that the ends of the drivers drive the nails flush
with the lower surface of the heel at the same moment that the edge of the breasting
knife comes flush with the sole, or completely breasts the heel. In case the nails are
desired to project slightly from the lower face of the heel, the drivers are made shorter.
The purpose of this is to cause the heads of the nails to project sufficiently from the
heel to allow the top lift to be "spanked" on, that is, the top lift is forced against
the ends of the nails which project from the partially formed heel to cause the
nails to penetrate the top lift and thereby allow it to take its place and complete
the heel.
When the driver plate a has risen almost far enough to drive the nails and breast
the heel, the cross piece a³ and its collar a³ come in contact with the sleeve plunger a¹º,
and as the mould D is secured to the upper end of this sleeve plunger a, mould D is
forced upwards by the rise of the plunger a and during the rest of the stroke
(a little over of an inch in most cases) the plunger at a³, sleeve plunger a

page_text: mould D, driver plate af and breasting knife F rise together compressing the heel
powerfully not only from top to bottom, but also around the back, sides and breast.
The plungers at, as are so adjusted in position that the upper surface of the driver
plate a comes in contact with the under surface of the heel block (see Figures 14
and 15) just before the plunger a' reaches its highest point, and consequently the heel
block d is forced up slightly with the mould D and driver plate a giving the final
compression to the heel. The heel block d, having remained stationary during part
of the upward movement of sleeve plunger a0 and mould D, the heel block d will be
slightly lower in the mould D at the end of the upward stroke of the mould D than
is shown in Figures 2 and 3. Its relation with the mould D at the extreme upper
stroke of the plungers a¹, a³ and sleeve plunger al is clearly shown in Figures 14, 15
and 16 which illustrate the relation of the heel block d and its spline G with the
mould D and sleeve plunger a10 when the sleeve plunger and mould are at the upper
end of their stroke.
The block a then descends and carries down with it the plungers a¹ a³ which are
connected to the block a² by means of cross piece a³ and rods 3; the first part of the
downward motion of plungers a³, a³ carrying the driver plate a and breasting
knife F down and the latter part of the downward motion of the block a² and
plungers at a pulling down the plunger sleeve a¹º and mould D by means of the
rods 4, 4. But as the legs of the heel block d are connected by the spline G which
rests upon the cross piece a' of the frame, the mould D travels down further than the
heel block d thus freeing the heel from the mould D and leaving it between the shoe b
and the heel block d. The double jointed arm B is then swung out of the way so
that the heel, or the shoe with the heel attached, is readily removed and a new one
inserted ready for the next operation like that just explained.
It will be seen that where a spring 5 is used to control the block a³ as shown in
Figure 2 that block will be withdrawn by the spring 5 as soon as the block a² begins
its downward motion. In order to adjust the plunger as I make it with a screw stem
which screws into the plunger a¹ and use a check nut 6 which not only prevents
accidental motion of the plunger a³ with relation to the plunger a, but also serves to
hold the cross piece as fast to the plungers at a thereby enabling cross piece a³ to
be used to connect the plungers a¹ as with the block a² and also with the sleeve
plunger a10.
The double jointed arm B has its upper end 63 formed with a screw thread which
enters an adjusting screw 64. The screw end 63 of the arm B is prevented from
moving on its axis by the spline 6 which is fast to the box 66. This box 66 can move
slightly in the cross piece a of the frame but has within it a rubber or other spring 67
the tension of which can be adjusted by the screw 68 and follower 6. In practice the
tension of spring 6' will be so great that the arm B and its connections will be held
down upon the heel with the requisite force.
Figures 7, 8 and 9 illustrate a nail carrier for feeding the nails to the heel block.
The nail holes in this carrier H are filled with nails being retained in place by the
slide 'h, then the pins are inserted in the holes 2 in the upper surface of the heel
block d of Figure 6, and the slide h is moved on its axis until the holes through it
co-incide with the holes in the carrier H, and the nails fall from the carrier H heads
down into the heel block d. After the heel block has thus been supplied with nails,
the heel is put and clamped firmly in place and the operation is as above described.
In order to give each nail a slight slant towards the middle of the heel the drivers
are slanted on their upper ends, as illustrated in Figures 10, 11 and 17; and these
slanted ends cause each nail to slant slightly towards the middle of the heel, see
Figure 17. The heads of the drivers are so formed that when clamped in place on
driver plate as the upper surface of each driver will slant properly. The nail holes in
the heel block d are also drilled on a slight slant, that is converging slightly towards
the middle of the heel, when the heels are concave. But for ordinary heels, slanting the
acting ends of the drivers will be sufficient to insure the proper insertion of the
nails without previous pricking.

page_text: The said patent No. 327,652, above referred to, the mould, driver plate and breast
knife were actuated by a single plunger, and the manufacture of niy present invention
consists in making the mould independent of the driver plate, whereby I am enabled
to greatly reduce the stroke of the mould and also to use the mould as a means of
correctly placing the heel; two matters of prime importance, as will be clear to all
skilled in this art.
While the breast knife may be attached to the mould, as in my former patent, it
is much better to attach it to the driver plate, as in my present machine, as
thereby the stroke of the mould may be made less than the stroke of the breast
knife; and while the main feature of my present invention consists in the combination
of the mould and driver plate so that the stroke of the former is only a part of
the stroke of the latter, and while this feature may be embodied in a machine in
which the breast knife is fast to the mould as in my former patent, yet to
obtain all the advantage of this feature of my invention, the breast knife
should move with the driver plate instead of being fast to the mould as in my
former patent.
I am aware of the United States Patents of Bigelow No. 108,677 of 1870 ;
Couburn No. 230,242 of 1880, and Straffin No. 214,533, of 1879, and disclaim all
that is shown in them.
In particular it will be observed that none of those patents show the holding arm
for the heel which can be swung out and in on one joint and which can also be
caused to firmly clamp the heel after it is swung in place by means of a second joint.
The novelty of this part of my invention over what is shown in the patents above
disclaimed, is that the holding arm is readily swung into place, as in the Bigelow
patent, above referred to, but then by means of the second joint it is forced with
great pressure down upon the heel thereby locking the holding arm in place, and
also firmly clamping the heel so that the holding arm cannot be swung out of place
or get out of place accidentally until the second joint is operated to unlock it and
relieve the pressure of the holding arm upon the heel; and this is the main novelty
of this part of my invention.
Having now particularly described and ascertained the nature of the said invention
and in what manner the same is to be performed as communicated to me by my
foreign correspondent I declare that what I claim is :-
First. In a heeling machine, the double jointed arm B, in combination with the
heel block d, the joints being arranged as shown in order that the arm B may be
easily swung on the upper joint to bring its shoe b over the heel block d, and then
by means of the lower joint be pressed with great force upon the heel and clamp
the heel between the shoe b, of the arm B, and the heel-block d, all substantially as
described.
Second. In a heeling machine, mould D and driver plate a and mechanism
substantially such as described for moving driver plate a within mould D for a
certain part of the stroke of the driver plate as, and moving mould D and driver
plate a together during the latter part of the stroke of the driver plate aº, the
mould, driver plate and actuating mechanism being combined and operating substantially
as described.
Third. In a heeling machine, mould D, heel block d, driver plate a and breasting
knife F, the breasting knife being fast to the driver plate a in combination with

the stroke of plunger a; but these plungers are moved together during the latter
part of the stroke, all substantially as and for the purpose specified.
Fourth. In combination heel block d, mould D, driver plate a and especial
mechanism for combining them, consisting of spline G and plungers as a, all
substantially as described.
