JAMES JUDGE, of No. 57, Bondgate, Bishop Auckland, in the County of Durham,

SHOES.".
We employ rolls fitted with steel punches and dies to give to a bar of red-hot iron
intended to be made into horse-shoes the creases, chamfers, tips, and swellings, as is
well understood, and the indentations or punch holes for nails at regular distances.
We construct the rolls and their fittings so as to make the parts most liable to
wear or fracture easily removeable, and to provide the requisite changes for different
sizes of shoes. We pass the bar so prepared at a red heat into a moulding machine,
where, the length being regulated by an adjustable stop, a portion sufficient for one
shoe is severed by a circular saw or other appliance. Immediately on its severance
it is by the movement of a shaping block pressed against the ends of a pair of jaws,
and caused, slightly to bend the wide way into the shape of a bow, being prevented
from bending, in any other direction by a groove in the jaws and a grooved moveable
guide held up to its first position by spring or counterpoise, and displaced gradually,
as the shoe is bent, by the shaping block. By the continued movement of the
shaping block the bow becomes more bent, and at the same time movement is com-
municated to the moveable guide and to the jaws, so as partially to close the latter
upon the bow formed by the shaping block. By this combination of simultaneous
movement of the shaping block and the enclosing jaws the desired degree of curve
may be given to the shoe, and it can be made more narrow at the heel than at the
middle, the shaping block bending it at the crown of the arch, and the enclosing
jaws nipping it in at the base of the arch approximately to the figure of the shaping
block.

At the end of the movements above described, and while the enclosing jaws
remain stationary, two projecting snuggs on the shaping block are brought by its
continued descent into contact with the ends of the partially formed shoe, which
projecting beyond the support are thus bent downwards and form heels.
arriving at the end of its downward stroke the shaping block is caused to ascend
through the shoe; the jaws are sprung open by counterpoise arrangement or springs,
and the finished shoe is by the return of the guide before referred to thrown from
the machine, which is then ready for a second operation.
The various parts of the machinery described, implicated in the regulation of a
certain size of shoe, are attached by bolts or otherwise to the parts-required for
every size of shoe, so as to be interchangeable, and parts more specially liable to
wear or fracture are made adjustable or easily renewable.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Luke Haslam and James Judge in the Great Seal Patent Office on the
12th June 1877.
LUKE HASLAM, of No. 13, Oxford Street, Newcastle-upon-Tyne, Gentleman, and
JAMES JUDGE, of No. 57, Bondgate, Bishop Auckland, in the County of Durham,
Engineer. "IMPROVEMENTS IN MACHINERY FOR THE CONSTRUCTION OF HORSE-
SHOES.
This Invention consists in a machine for cutting off, forming up, and heeling
horse-shoes from a continuous bar of metal or from a bar of shoe blanks formed by
rolls or other machinery, with the creases, chamfers, tips and swellings, and with
indentations or punch holes for nails, as is well understood.
Figure 1 represents a front view, Figure 2 a side view partly in section of the
moulding machine, and Figure 3 a plan of the same, with the crank, connecting
rod, and shaping block removed.
The prepared bar is passed at a red heat into the moulding machine up to an
adjustable stop a, as shown by the Drawing, and a portion sufficient for one shoe is
severed by a circular saw b or other appliance, the bar near to where it is being cut
then bearing against another stop a¹.
In the arrangement shown in the Drawing the axis of the saw is carried by
swinging links, and the saw is caused to move forwards at the time required to
sever the bar by a cam or eccentric on the main shaft of the machine, as shown at
Figure 2. Immediately after the bar has been severed, the severed portion is by
the descent of a shaping block c pressed at its centre into a groove in a moveable
guide e, whilst its ends are brought against a pair of jaws d, d, and it is thereby
caused slightly to bend the wide way into the shape of a bow, being prevented from
bending in any other direction by a groove in the jaws d, d, and the groove in the
guide e; this guide is held up to its first position by a spring or counterpoise f, and
is displaced gradually as the shoe is bent by the shaping block c. By the continued
movement of the shaping block the bow becomes more bent, and at the same time
movement is communicated to the moveable block g and to the jaws d, d, so as
partially to close the latter upon the bow formed by the shaping block.
In the arrangement shown in the Drawing the jaws & turn upon pivots d², and
are also jointed to the moveable block g, which is pressed forwards by a spring.
When the back end of the moveable guide e comes against the back end of the
jaws d and the block g the jaws are caused to turn inwards, and bend the shoe
around the shaping block. By this combination of simultaneous movement of the
shaping block and the enclosing jaws the desired degree of curve may be given to
the shoe, and it can be made more narrow at the heel than at the middle, the
shaping block bending it at the crown of the arch and the enclosing jaws nipping
it in at the base of the arch approximately to the figure of the shaping block.

page_text: At the end of the movement above described, and while the enclosing jaws remain
stationary, two projecting snugs h, h, on the shaping block are brought by its con-
tinued descent into contact with the ends of the partially formed shoe, which
projecting beyond the support are thus bent downwards and form heels, or if the
shoe is not required to be formed with heels the snugs h, h, are not required. On
arriving at the end of its downward stroke the shaping block is caused to ascend
through the shoe, the jaws are sprung open by counterpoise arrangement or springs,
and the finished shoe is by the return of the guide e thrown from the machine,
which is then ready for a second operation.
It will be seen that the various parts of the machinery described, implicated in
the regulation of a certain size of shoe, are all connected together, and can readily
be changed for other parts suitable for making a shoe of different size, the parts
for making every size of shoe being thus interchangeable; also the parts more
especially liable to wear or fracture are readily adjustable or renewable.
Having now described the nature of our said Invention, and in what manner the
same is to be performed, we declare that we claim as our improvements in machinery
for the construction of horse-shoes, the combined apparatus for bending and heeling
shoes, or for bending alone, substantially as described.
In witness whereof, I, the said Luke Haslam, have hereunto set my hand and
seal, this Eighth day of June, in the year of our Lord One thousand eight
hundred and seventy-seven.
