DAVID STEWART, of the City and County of Aberdeen, North Britain, Master of
Arts. IMPROVEMENTS IN TREATING HORNS AND HOOFS FOR THE PURPOSE OF
MANUFACTURING ARTICLES THEREFROM AND IN APPARATUS THEREOF."
This Invention which relates to improvements in treating horns and hoofs for
the purpose of manufacturing articles therefrom, consists essentially in the appli-
cation of heated air for the purpose of opening, flattening, pressing, striking,
cutting, bending, strengthening, and generally operating upon horns and hoofs in
lieu of steaming or roasting them as at present adopted.
In carrying out this Invention, chambers or baths, constructed of copper or other
good conductor of heat on the inside, and of a non-conducting material or metal
covered with a good non-conducting substance on the outside, are used, that is to
say, the chambers are double cased in the order set forth, thus enclosing a space
into which either highly heated air or steam is conveyed.
The inside conducting coating throws off as much as possible of the heat to the
interior of the chambers or baths, and by placing the horns or hoofs into these
chambers or baths they are heated as required with or without the use of "tongs,"
or "plate tongs," or any other article commonly used in operating on horns or
hoofs.
The openings of the chambers or baths may or may not be provided with covers
or lids as required, and the chambers or baths are, when necessary, charged with a
non-conducting powdered substance, such as sawdust or uninflammable paper in
which the horns or hoofs are embedded until they are raised to the temperature
requisite for the operations herein-before mentioned, but the baths may be used
without a non-conducting powdered substance.

the said David Stewart in the Great Seal Patent Office on the 3rd October
1876.
DAVID STEWART, of the City and County of Aberdeen, North Britain, Master
of Arts. "IMPROVEMENTS IN TREATING HORNS AND HOOFS FOR THE PURPOSE OF
MANUFACTURING ARTICLES THEREFROM AND IN APPARATUS THEREFOR."
My said Invention, which relates to improvements in treating horns and hoofs
for the purpose of manufacturing articles therefrom, consists essentially in the
application of heated air or steam for the purpose of opening, flattening, pressing,
striking, cutting, bending, straightening, and generally operating upon horns and
hoofs in lieu of heating or roasting them at open fires as at present adopted.
In carrying out this Invention, chambers or baths, constructed of copper or other
good conductor of heat on the inside, and of a non-conducting material or metal
covered with a good non-conducting substance on the outside, are used, that is to
say, the chambers are double cased in the order set forth, thus enclosing a space
into which either highly heated air or steam is conveyed.
The inside conducting coating throws off as much as possible of the heat to
the horns or hoofs, and so they are heated as required, with or without the use
of "tongs," or "plate tongs," or any other article commonly used in operating on
horns or hoofs.
The openings of the chambers or baths may or may not be provided with covers
or lids as required, and the chambers or baths are, when necessary, charged with
a non-conducting powdered substance, such as sawdust or uninflammable paper,
in which the horns or hoofs are embedded until they are raised to the temperature
requisite for the operations herein-before mentioned, but the baths may be used
without a non-conducting substance.
Having now described and particularly ascertained the nature of my said Inven-
tion, and the system, mode, or manner in or under which the same is or may be used
or practically carried into effect, I would observe in conclusion that what Ï 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, treating horns and hoofs with heated
air or steam in chambers or baths and with or without a non-conducting powdered
substance, substantially in the manner herein-before described.
In witness whereof, I, the said David Stewart, have hereunto set my hand
and seal, this Thirtieth day of September One thousand eight hundred and
seventy-six.
DAVID STEWART, M.A. (L.S.)
