Year: 1878

page_text: LETTERS PATENT to George Miller, of Whickham, in the County of Durham,
for the Invention of "IMPROVEMENTS IN APPARATUS FOR PUNCHING OR
HOLEING SHOES FOR HORSES AND OTHER HOOFED ANIMALS, OR BARS FOR SUCH
SHOES."
Sealed the 30th August 1878, and dated the 9th March 1878.
PROVISIONAL SPECIFICATION left by the said George Miller at the Office
of the Commissioners of Patents on the 9th March 1878.
GEORGE MILLER, of Whickham, in the County of Durham.
"IMPROVEMENTS
IN APPARATUS FOR PUNCHING OR HOLING SHOES FOR HORSES AND OTHER HOOFed
ANIMALS, OR BARS FOR SUCH SHOES."
My Invention relates to apparatus for forming holes in bars for shoes for horses
and other hoofed animals when hot at the different positions and angles required
for the nails of the shoes.
In carrying out my Invention I employ steel or other punches set in a moving
block (working in guides) at the required position and angles, and actuated by a
steam engine through the intervention of a crank and connecting rod, or by other
suitable means.
The horse-shoe bar when hot is placed in a block opposite to the punches, and
immediately behind the horse-shoe bar is fixed in the block a steel or other plate
or matrix, having holes corresponding to the position of the punches, and arranged
at such an angle as is required to give the proper direction to the nails.
The ends of the punches pass entirely through the horse-shoe bar, any burr, or
inequality that may be left on being subsequently removed by hand or machine.
The holing operation may be performed when the bar is straight or after it has
been bent into the form of a shoe, the whole of the holes for one shoe being produced
at one operation.
The punches are maintained in a cool condition by means of water jets.
The shoes may be provided with calks or "fallers."

GEORGE MILLER, of Whickham, in the County of Durham. "IMPROVEMENTS IN
APPARATUS FOR PUNCHING OR HOLING SHOES FOR HORSES AND OTHER HOOFED
ANIMALS, OR BARS FOR SUCH SHOES."
My said Invention relates to apparatus for forming holes in bars for the shoes of
horses and other hoofed animals, either in the straight condition of such bars or
after they have been bent into the shape or approximate shape of the shoes by
subjecting the bars when in a heated state to the action of a set of punches mounted
in or at the requisite positions or angles for the nails of the shoes in a reciprocating
frame, whereby the whole series of holes for a shoe are formed in a bar simultane-
ously at one operation.
And in order that my said Invention may be fully understood I shall now proceed
moro particularly to describe the same, and for that purpose shall refer to the several
Figures on the annexed Sheet of Drawings, the same letters of reference indicating
corresponding parts in all the Figures.
Figure 1 of my Drawings represents a longitudinal section of an apparatus for
holing horse-shoe bars before they are bent as an example of the mode of carrying
out my said Invention; Figure 2 is a plan of the same; and Figure 3 is a transverse
section taken along the line 1, 2, Figure 1.
a, a, are the punches, which may be arranged at any suitable angle and employed
in any required number, according to the direction and position of the nails of the
shoe to be produced. These punches are carried in a holder A, which with a cross
head B is attached by bolts b to a slide C, the latter being adapted to dovetailed
guides on a bed plate D, and operated through the intervention of a connecting rod c
and crank from any suitable prime mover or otherwise, so as to receive with the
punches a a reciprocating to-and-fro motion.
The bar E to be holed is supported against the steel or other facing or matrix d
of a block F, which is attached by bolts or screws e to the bed plate D, both the
matrix and the block being perforated, as shewn at f, g, respectively, and arranged
so that the matrix shall be placed at the required angle.
Assuming the apparatus to be in motion, and the slide C to be performing its
back stroke, a bar E is placed in a heated condition against the matrix d, with one
end abutting against a stop h, and on the return stroke of the slide C in its forward
direction the ends of the punches a, a, are caused to pass through the bar E and to
enter the matrix d, the metal punched out of the bar being discharged through the
perforations g in the block F, and any burrs or inequalities left on the bar being
subsequently removed by hand or otherwise. During the next back stroke of the slide
C the perforated bar is removed and replaced by another heated bar, to be punched
in its turn on the next fore stroke of the slide, and so on in succession during the
operation of the apparatus.
A guard plate G is provided in order to retain the bar E on the withdrawal of
the punches a, a, after the operation of punching the holes in such bar. Provision
is made for adjusting the position of the punches before the operation is commenced,
slots i being formed, through which the bolts 6 pass, and distance pieces, such, for
example as is shewn at H, being provided, one of which is interposed between the
surface of the slide at h' and the cross head B, as shewn, in order to receive the end
thrust.
The block F may also be made adjustable laterally by means of set screws, as
shewn at k, in order to ensure an exact "register" or coincidence of position with
the punches before the apparatus is started.
The punches are maintained in a cool condition by water jets, as shewn at l.
By means of my said Invention the whole of the holes for one shoe are produced

page_text: simultaneously at one operation, thus economising time and labor, whilst the
efficiency of the operation remains unimpaired.
It is obvious that the shoe so produced may be either plain or provided with
"calks" or "fullers" of any ordinary description.
When it is required to form the holes in the bar after it has been bent it will be
simply necessary to suitably arrange the position of the punches in their frame and
of the holes in the matrix and block, and the operation may be carried out in the
manner herein-before described.
Having now described and particularly ascertained the nature of my said Invention
and the manner in which the same is or may be used or carried into effect, I would
observe in conclusion that what I consider to be novel and original, and therefore
claim as the Invention secured to me by the herein-before in part recited Letters
Patent is, punching or holing bars for shoes for horses and other hoofed animals,
either in the straight condition of such bars or after they have been bent into the
shape or approximate shape of the shoes by subjecting the bars when in a heated
state and maintained at a suitable angle to the action of a set of punches mounted
in or at the requisite positions or angles in a reciprocating frame, whereby the whole
series of holes for a shoe are formed simultaneously, each hole being adapted in
position and angle to the nail which it is intended to receive, substantially as herein-
before described.
In witness whereof, I, the said George Miller, have to this my Specification
set my hand and seal, the Sixth day of September, One thousand eight
hundred and seventy-eight.
