WILLIAM ROBERT LAKE, of the Firm of Haseltine, Lake, & Co., Patent Agents,
Southampton Buildings, London. "IMPROVEMENTS IN ROLLING MACHINERY TO
BE USED IN THE MANUFACTURE OF HORSE-SHOES." A communication from abroad
by Theodore Stafford Very, of Boston, Massachusetts, United States of America.
This Invention relates to rolling machinery to be used in the manufacture of
horse shoes.
According to the said Invention I provide a pair of rolls for rolling the blanks,
which rolls are adapted to punch the bar on two opposite sides in such manner as
to form cavities on each side, the cavities of one side coinciding with those on the
other side, and being separated therefrom only by thin films or webs of metal, so
that when the said films or webs are removed continuous nail-holes will be formed
extending through the bar, said holes being inclined transversely to the bar. To
this end the Invention consists in the peculiar construction of the rolls, which I
will now proceed to describe.
In the accompanying Drawing,
Figure 1 is a front view of a pair of rolls embodying my Invention.
Figure 2 is a section on the line 1, 1, and
Figure 3 a section on the line 2, 2, Figure 1.
Figure 4 is a section on the line 1, 1, Figure 4, showing the rolls partially rotated
from the position shown in Figures 1 and 2.
Figure 5 is a plan or top view of a portion of a blank after the same has been
subjected to the action of the rolls.
Figure 6 is a section on the line 3, 3, and
Figure 7 a section on the line 4, 4, Figure 5.

page_text: Figure 8 represents a plan or top view of a blank shewing the thickened
portions from which the heel calks are subsequently formed.
Figure 9 is a section on the line 5, 5, Figure 8.
Figure 10 represents a detached view of a modification of my Invention herein-
after described.
Like letters indicate the same parts throughout the Drawing.
A, B, represent the said rolls, which are located in suitable bearings and geared
so that they will be rotated positively in opposite directions. The roll A is
provided with flanges C, C', and its periphery between these flanges has the forin
of a frustum of a cone increasing in diameter from the flange C to the flange C'.
These flanges C, C', prevent lateral splaying of the metal being rolled, and condense
it longitudinally. They also prevent the formation of fins, which are always forined
by the use of dies. Hence with this roll I an enabled to produce a bar free
from fins and ready for immediato use in forming shoes, simply requiring to be
bent and provided with proper calks. D is a creasing die located on the periphery
of the roll A. This die is adapted to form an uninterrupted crease or groove k in
a bar I every time the roll A revolves (the bar passing between the rolls A, B), and
these creases are so spaced or separated from each other that each constitutes the
crease for one blank of the series, said crease extending around the toe when the
blank is bent into a shoe. The die D is provided with punches P arranged in two
series, these punches being so located as to form cavities c in one side of the bar I,
these cavities extending into the bar from the creases h. Tho roll B fits somewhat
closely between the flanges of the roll A, as shown in Figure 1, and is provided on
its periphery with punches P¹, which are so arranged as to coincide with the
punches P, and form cavities c¹ in the bar I, these cavities being opposite the
cavities c, as shewn in Figure 9, and separated from the latter only by thin films
or webs of metal, by the removal of which the cavities c, c', are united to form nail
holes. The inclination of the periphery of the roll A causes it to support the bar I
in an inclined position. The die D is inclined or bevelled on the side adjacent to
the flange C, and its opposite side is vertical and consequently stands at an acute
angle with the transverse surface of the roll A, as shewn in Figure 1.
By this construction the die D and its punches P are caused to enter the bar I
obliquely to the bottom 'surface thereof, and thus form creases and cavities c,
which are inclined transversely of the bar.
The punches P¹ are located in a vertical plane, which is slightly separated from
and is parallel with the vertical plane, in which the punches P and die D are
located, the arrangement of the punches P¹ being such that the cavities c' formed
thereby will be inclined in continuation of the cavities c, as shewn in Figure 7, so
that when the cavities c and c¹ are connected by the removal of the separating
webs the continuous holes will have a regular inclination transversely of the bar,
this inclination when the bar is bent into shape as a shoe corresponding to the
inclination of the shell of a horse's hoof so as to guide the shoe nails in the proper
direction. The roll B is reduced on one side between the two series of punches P¹,
as shown at R, Figures 2 and 4, this reduced portion giving the bar an increased
thickness at the points where the bar is to be severed or cut up into blanks, as
shewn in Figures 8 and 9, the point where the bar is to be cut being indicated in
said Figures by dotted lines. When the bar is thus cut each length is adapted to
be bent into a shoe, and is thicker at its ends than along the intermediate portion.
These ends afford material for the heel calks. The roll B is provided with a
bevelled enlargement or projection E; on the side opposite the reduced portion
this projection is located by the side of the punches P1, and adapted to impart a
bevel or "seat" to the upper surface of the bar, as shewn in Figures 5 and 6.
I do not limit myself to the described shape of the roll B with reference to
bevelling or seating the bar and forming the thickened portions, as the periphery
of the roll may be made perfectly concentric with its axis if desired.
If desired the punches may be omitted from the creasing die, the punches on the
roll B being made long enough to nearly meet the creasing die.

page_text: The creasing die may be omitted and the punches P may be located on counter
sinking dies G, as shown in Figure 10, each die G being adapted to form an
enlarged cavity adapted to receive the head of a horse shoe nail.
The punches P, P¹, may be arranged to make vertical instead of inclined
cavities in the bar without departing from the principle of my Invention.
I prefer to make the roll B inclined or tapering transversely, so that its lowor
surface will be parallel with the upper surface of the roll A, along the vertical
plane of the axes of the two rolls, excepting where the enlargement E occurs.
Having thus fully described the said Invention as communicated to me by my
foreign correspondent, and the manner of performing the same, I wish it under-
stood that I claim,—
First. A pair of rolls having punches adapted to enter a bar of iron on opposite
sides and form coinciding cavities which are inclined transversely, as above
set forth.
Second. The roll B, having the die or enlargement E and punches P¹ combined
with the roll A, having punches P as above set forth.
Third. The roll A constructed, as shown, with flanges in combination with the
roll B, to match or correspond therewith, substantially as herein specified.
In witness whereof, I, the said William Robert Lake, have hereunto set my
hand and seal, this Twenty seventh day of March, in the year of our Lord
One thousand eight hundred and eighty.
