Improvements in or relating to Heeling Machines.
We, TOM PEBERDY, WILLIAM EARP and THOMAS HERBERT PARR, Boot and Shoe
Machinists, of 45 Farnham Street, Leicester, do hereby declare the nature of this
invention to be as follows:-
Our invention relates to improvements in machines for building and attaching heels
to boots and shoes and consists more particularly in providing mechanism to hold and
compress the heel in a firm and rigid position whilst the pins are forced through the
heel.
To carry out our invention we mount upon a pair of standards a horizontal bed.
On each side the machine and outside the standards is a vertical slide, capable of
moving up and down in a guide formed on the standards. These vertical slides reach
a sufficient height above the bed of the machine to allow of the insertion of the heeling

the said beam to allow of the adjustment of the heeling mechanism and carries at its
lower end the ram for pressing upon the heel. The machine is driven by means of a
pulley mounted upon the end of a horizontal shaft having its bearings a suitable
height up the standards. Carried on the driving shaft is an eccentric and also a
pinion gearing into a spur wheel which revolves loosely upon a shaft under the bed
and preferably on the centre of the machine. This shaft which may be termed an
eccentric shaft, has an eccentric or crank on each end to give motion to the
vertical slides.
Pivotted near the bottom of the machine is a treadle connected by a vertical rod or
equivalent to a bracket on the inside of one of the standards and capable of an up and
down movement; this bracket is preferably circular with a lug top and bottom to
work in guides fixed to a standard and is provided with an opening at or near its
centre to enable it to span or enclose the eccentric shaft before mentioned. The upper
part of the bracket may be suitably hollowed to partly receive a ball or equivalent the
other part of the ball fitting into a hollow or recess in the end of a lever forked to
partly enclose the eccentric shaft and connected to the latter by suitable means. The
upper end of the forked lever is constructed to gear into a clutch formed preferably
integrally with the spur wheel on the eccentric shaft.
Carried by the eccentric shaft is a collar or equivalent furnished with a lug or other
projection which on revolving with the eccentric shaft comes into contact with the lower
end of links attached to the bottom of the plunger.
When the heel is in position on the holder, the operator's foot is placed upon the
treadle and forces down the circular bracket spanning the eccentric shaft. This action
forces the ball contained in the said bracket forward and carries with it the upper end
of the forked lever which immediately gears with the clutch on the side of the spur
wheel on the eccentric shaft. This causes the eccentric shaft to partly revolve and
by means of the eccentrics or cranks on the ends of the said shaft lowers the vertical
slides and with them the cross beam and ram, a required distance. By this time the
lug on the collar which actuates the plunger will come into action and with it the
eccentric of the driving shaft and forcing up the plunger drive the pins home through
the heel at the same time that the ram presses thereon.

page_text: Machinists, 45 Farnham Street Leicester 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 :-
This invention has reference to machines for building heels and attaching same
to boots and shoes, and embodies improvements which have for their object the pro-
vision of mechanism for compressing pieces of leather and holding them firmly and
rigidly in position whilst the pins or nails are driven through them during the process
of building or attaching.
In the accompanying drawings
Figure 1 is a view below the bed of a heel building and attaching machine, showing
the mechanism comprised in this invention.
Figure 2 is an inside view of one of the vertical slides to show the shape of the
eccentric groove or slot (3.
Figure 3 is a section taken on the line Y. Z of fig. 1 looking towards the bracket H.
Figure 4 is a view partly in section to shew the inside face of the clutch J.
Figure 5 is a plan of the cam bar H¹.
A. A are the standards upon which is mounted a horizontal bed B upon which the
building and attaching stands are placed. On the outer side of each of the standards
is a vertical slide capable of being moved up and down in guides C on the
standards A and A'. These vertical slides C extend a sufficient height above the
bed B of the machine to allow of the ordinary heel building and attaching stands
being placed on the latter, and are connected at the top by an ordinary cross-beam
through which passes an adjusting screw having on its upper end an ordinary hand
wheel and carrying on its lower end the usual block and lie for pressing upon the
heel when the pins are being driven through the leather. So far as described the
machine is of the ordinary construction.
.
The machine is driven by means of a pulley E¹ mounted upon the end of a hori-
zontal shaft E having its bearings in the standards A. A' and carrying also the
pinion E gearing into the spur wheel F revolving loosely upon the shaft F.
This shaft, at each end, has an eccentric or crank F with a loose collar sto
impart motion to the vertical slides C. The shaft F in its normal condition is
stationary and remains so until set in motion by the mechanism as hereafter described.
The treadle G working on a pivot G¹ is connected by means of rods G², G³ to the
cam-bar H supported on the springs encircling the rods H2 fixed in the bosses H³
of the circular bracket H.
The bracket H is secured by bolts passing through the holes H to the inside of
the standard A', and is also provided with an opening in its centre to enable it to
span or enclose the shaft F.
The shaft F has a slot F, figs. 3 and 4 to receive a lever J having a tooth J' to
engage with the clutch J2 (figs. 1 and 4) formed at the side of, and preferably
integrally with, the spur wheel F. The lever J is pivotted or otherwise secured to
the shaft F and on gearing with the clutch J will revolve and carry the shaft F round
with it. The roller J³ rotates in contact with the face of the bracket H to keep the
lever J in gear with the clutch J².
The action of the machine during a single operation of building or attaching is
as follows: The operator by means of his foot having depressed the -treadle G,
the rods G2 and G³ cause the cam-bar H' to descend a sufficient distance to allow
the lever J, (shown in its normal position in fig. 3), to be impelled forward by the
spring J, fig. 1 and the tooth J to engage with the clutch J² on the side of the
spur wheel F and set the shaft F in motion.
When the eccentrics or cranks F2 cause the vertical slides C to descend, the cross-
bar above the bed of the machine will bring the block and die down to compress

page_text: the heel on the stand. The cam groove or slot C³ on the vertical slides C, as shown
in fig. 2, is so shaped as to allow the ordinary block and die compressing the heel to
dwell or rest until by means of mechanism described in the specification of our
Patent No. 19637 of 1889 the plunger is forced upwards thereby driving the nails
through the heel, in the ordinary manner, at the same time that the block and die
press thereon. The shaft F will continue to revolve with the spur wheel F' until the
roller J on the end of the lever J reaches the foremost end H³ of the cam-bar H',
fig. 5, which, (as the operator's foot will now be removed,) has by this time been
returned to its normal position by means of the springs H and passing along the back
of the cam-bar withdraws the tooth J on the lever J out of gear with the
clutch J².
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is
1. In a heeling machine the combination with a clutch such as J' of a lever such
as J mounted in the shaft which carries the clutch and adapted to be engaged with the
clutch by a cam-bar such as H¹ substantially as and operating in the manner and for
the purpose herein described and illustrated in the accompanying drawings.
2. In a heeling machine the combination in the vertical slides C of a groove or slot
shaped or adapted to cause the block and die to remain compressing the heel during
the ascent of the plunger substantially as described.
3. The improved machine constructed, arranged, and operating substantially as and
for the purpose herein described and illustrated in the accompanying drawings.
