WILLIAM ROBERT LAKE, of the Firm of Haseltine, Lake, & Co., Patent Agents,
Southampton Buildings, London. "LIMPROVEMENTS IN THE FORMATION OF METAL
BARS FOR THE MANUFACTURE OF HORSE-SHOES, AND IN MACHINERY THEREFOR." A
communication from abroad by William Morris Greenwood and John Norris Clarke,
both of Cincinnati, Ohio, United States of America, Manufacturers.
This Invention relates to improvements in the construction of bars, or blanks, and
to machinery for forming the same, its object being to produce a blank ready to be
bent or formed into a horse-shoe having a corrugated ground surface or series of
calks located at equidistant points limited in number by the size of the shoe. The
calks or corrugations generally range from nine to eleven, and while giving a plain
surface for the tread of the horse present so many obstacles to slipping that on the
most uneven or slippery surfaces the tread of the horse is made absolutely firm and
secure.
My Invention also has for its object the placing of the "fullering" or nail creases
on the outside of the web while the continuous calks are located on the inside, the
said "fullering" creases being on a plane above the lower surfaces of the calks, thus
preventing the wearing out of the nail heads or the rising of the clinches, and
keeping the shoe firin in its place much longer than an ordinary shoe.
The said Invention comprises, first, an improved horse-shoe blank constructed
with a corrugated ground surface of calks located at equidistant points, and a
"fullering" or nail crease on the outside of the web above the corrugations or
calks.

page_text: The said Invention comprises, secondly, an improved method of forming
blanks by subjecting a plain blank successively to the action of a series of suitable
dies.
The said Invention comprises, thirdly, two rolls journalled in suitable standards
and working together, and provided with a series of dies and counter dies between
which the blanks are successively passed in process of construction.
Also a die for forming the corrugations or calks, and the nail crease upon the
blank constructed with convex projections for forming the calks, and an angular
shoulder for forming the fullering.
Also a pair of rolls, one of which is provided around the periphery with a dio
whose face is formed with a series of convex projections at regular intervals, the
other having a plain counter die, and both being arranged to work together to
produce a series of corrugations upon the blank when the same is run between
them.
DESCRIPTION OF THE DRAWING.
Figure 1 represents a front elevation of a set of rolls showing the said improve-
ments; Figure 2 represents a transverse section through the line x, x, Figure 1;
Figure 3 represents a front view of a modification of the said rolls; and Figure 4
illustrates in several views the blank in process of formation. This Figure is drawn
to an enlarged scale.
A and B represent a pair of rolls journalled in standards C, C, at each end, and
arranged in such relative positions that the dies on their peripheries will work
properly together. The roll B is provided with a series of dies a, b, c, d, and the
roll A with a series of counter dies a, b, c, d, by which the strip of metal or blank is
gradually brought to its proper shapo previously to being passed through or between
the corrugating dies D, E, the said blank being formed by successive passes between
tho dies and counter dies, beginning with a and a', and ending with d and d¹, by
which it is formed with a thin web to fit the sole of the foot and a projection for
the tread, the rim being the portion to be corrugated in the next operation when
the blank is passed between the dies D and E. The die E is preferably formed
around the periphery of the roll B, its face being constructed with a series of convex
projections or teeth e at regular intervals apart. The counter die D is formed upon
the upper roller, and has a plain face which works into the die E upon the lower
roll. Around the face of the lower die is formed an angular shoulder ƒ which forms
the nail crease in the blank.
The operation of the said rolls is as follows:-The metallic bar is first passed
between the dies a and a¹, by which a shape in cross section similar to that illus-
trated by the letter M, Figure 4, is given to it; it is then passed between dies b and
b which give it the shape shown by n, Figure 4, after which it is reversed and
passed between dies c and c¹ taking the shape shown by o of the last-mentioned
figure, and is then finally brought to the proper shape to be subjected to the action
of the corrugating rolls by passing between the dies dand d¹ which form it, as indi-
cated by p, Figure 4. The blank in this last-mentioned condition is passed between
the dies D and E, by which the corrugations in the rim are formed and the nail or
fulling" crease produced. is a side view of the bar or blank.
"
Having thus fully described the said Invention, as communicated to me by my
foreign correspondents, and the manner of performing the same, I wish it understood
that I claim,
First. A horse-shoe blank constructed with a corrugated ground surface of calks
on the inside of the web, and a "fullering" or nail crease on the outside of the web,
as and for the purposes herein described.
Second. The improved method of forming the horse-shoe blanks by subjecting
the plain blank successively to the action of differently shaped dies, as herein set
forth.
Third. The improved machine for constructing the horse-shoe blanks composed of
two rolls journalled in suitable standards and working together, and provided with

page_text: dies and counter dies between which the blanks are successively passed, and by
which they are finally finished, as herein set forth.
Fourth. The die for finishing the blank provided with a series of convex pro-
jections for forming the corrugations or calks, and an angular shoulder for forming
the "fullering" or nail crease, as herein set forth.
Fifth. The combination of the rolls, one provided with a die with convex pro-
jections and shoulders upon its face for forming the corrugations and nail crease
upon the shoo blank, the other being provided with a plain counter die, both being
arranged to work together, as above described.
In witness whereof, I, the said William Robert Lake, have hereunto set
my hand and seal, this Ninth day of March, in the year of our Lord One
thousand eight hundred and seventy-seven.
