County of York, for an Invention of " AN IMPROVED MANUFACTURE OF HORSE-
SHOES."
PROVISIONAL SPECIFICATION left by the said Thomas Brown at the Office
of the Commissioners of Patents on the 8th September 1881.
THOMAS BROWN, of Regent Works, Sheffield, in the County of York. “An
IMPROVED MANUFACTURE OF HORSE-SHOES."
According to my Invention I construct horse shoes of bars or plates of iron or
steel, having a width corresponding to the width of the horse shoe, which are
rolled with their one face flat, while the other face is formed with a continuous
series of narrow and deep transverse corrugations or ribs extending across the bar.
This face of the bar may also have longitudinal grooves rolled along it, or such
grooves may be made to extend only partially along the face of the bar by stamping
after the bar is rolled. A length of straight bar such as above described having
been heated, it is bent round into the required-shape-of-the-shoe-in-such-a-manner
that the flat or plane surface forms the side that is fitted against the hoof, while
the corrugated surface forms the underside of the shoe, which in thus presenting
a number of narrow projecting ribs to the ground affords great hold for the horses'
feet. The ribs being of some depth, and the shoes, particularly when they are
made of steel, being very durable, they will act efficiently for a considerable time,
namely, until the ribs are entirely worn off, and these may be occasionally
sharpened by filing, so as to afford increased hold. Owing to the corrugated form
of the bar it is more easily bent into the required shape of the shoe than the
ordinary solid iron or steel bar, and, while affording a greater amount of efficient
wear than these, is of considerably less weight. As the shoe when finished requires
to be somewhat dished on its flat side, that is, with the surface sloping downwards
towards the middle, the bar is by preference made in the first instance with
the tops of the corrugations or ribs slightly inclined or of less height on the inner
than on the outer side, so that when bent into the form of the shoe and dished to
the required extent the tops of the corrugations will lie flat on the ground. The
holes for the nails are punched in the spaces between the projecting ribs or in the
longitudinal grooves, and the nail heads are protected by the projecting ribs until
these are worn down,

"AN
According to my Invention I construct horse shoes of bars or plates of iron or
steel, having a width corresponding to the width of the horse shoe, which are
rolled with their one face flat, while the other face is formed with a continuous
series of narrow and deep transverse corrugations or ribs extending across the bar.
This face of the bar may also have longitudinal grooves rolled along it, or such
grooves may be made to extend only partially along the face of the bar by stamping
after the bar is rolled. A length of straight bar such as above described having
been heated, it is bent round into the required shape of the shoe in such a manner
that the flat or plane surface forms the side that is fitted against the hoof, while
the corrugated surface forms the underside of the shoe, which in thus presenting a
number of narrow projecting ribs to the ground affords great hold for the horses'
feet. The ribs being of some depth, and the shoes, particularly when they are made
of steel, being very durable, they will act efficiently for a considerable time, namely,
until the ribs are entirely worn off, and these may be occasionally sharpened by
filing, so as to afford increased hold. Owing to the corrugated form of the bar it is
inore easily bent into the required shape of the shoe than the ordinary solid iron or
steel bar, and, while affording a greater amount of efficient wear than these, is of
considerably less weight. As the shoe when finished requires to be somewhat
dished on its flat side, that is, with the surface sloping downwards towards the
middle, the bar. is by preference made in the first instance with the tops of the
corrugations or ribs slightly inclined, or of less height on the inner than on the outer
side, so that when bent into the form of the shoe and dished to the required extent,
the tops of the corrugations will lie flat on the ground. The holes for the nails
are punched in the spaces between the projecting ribs or in the longitudinal
grooves, and the nail heads are protected by the projecting ribs until these are worn
down.
The accompanying Drawings illustrate various forms that may be adopted for
the ribs or studs rolled on the bar, a longitudinal section of part of which is shewn
at Fig. 1 and a plan at Fig. 1, A being the flat side, which is fixed against the
hoof, and B the projecting ribs or studs formed on the bar as it is rolled; Fig. 2
shews the horse shoe made from a bar having the ribs B. extending directly across
it; in Fig. 3, the ribs cross the bar obliquely; in Fig. 4, they have a bend or angle
in the middle; and in Fig. 5 they are curved. Figs. 2, 3, 4, and 5° shew ribs of
similar forms, with a longitudinal groove C extending partly round the shoe, this
groove being punched or impressed in the metal after it is rolled; and Figs. 2b, 3b,
4b, and 5 shew the longitudinal grooves C, or they may be projecting ribs extending
all round. As in these cases the longitudinal groove or rib is continuous it may be
formed when the bar is rolled. Figs. 2c, 3c, 4c, and 5c shew shoes having studs of
different forms projecting from them instead of ribs, the shapes of these as well as
of the ribs being susceptible of variation, as may be readily understood; Figs. 2ª,
3, 4, and 5ª shew shoes having oblique transverse ribs strengthened at their
exterior ends by longitudinal ribs, which, as shewn in Fig. 2d, may extend round
the whole external periphery of the shoe, or may be applied as shewn in Figs. 3d,
4d, and 5d only at the front part of the shoe, where greatest' strength is required.
Such longitudinal ribs are formed, like the transverse ribs, in the rolling of the
bar,

page_text: Having thus described the nature of my Invention, and in what manner the
same is to be performed, I claim,―
The manufacture of horse shoes by rolling bars of iron or steel flat on one side,
and having ribs or studs projecting on the other side, cutting these bars to suitable
lengths, and forging the lengths to shape, substantially as herein described.
In witness whereof, I, the said Thomas Brown, have hereunto set my hand
and seal, this Fourth day of March, in the year of our Lord One thousand
eight hundred and eighty-two.
THO. BROWN. (L.S.)
