SAMUEL OXLEY and THOMAS SMITH, both of Sheffield, in the West Riding of the
County of York. "IMPROVEMENTS IN MEANS AND APPARATUS FOR THE MANU-
FACTURE OF IMITATION OR ARTIFICIAL STAG HORN."
This Invention relates to the production or manufacture of imitation or artificial
stag horn and apparatus therefor.
This Invention consists in the production of imitation or artificial stag horn
from bone, wood, vulcanite, or similar or other substance by means of rotating
cutters, which will cut out of the aforesaid substances such parts thereof as will
cause them to have indentations similar to real stag horn.
In carrying into effect this Invention an apparatus of the following description
can be employed, that is to say-In suitably designed framework there will be
bearings for a shaft or spindle, which will be driven by a belt in the ordinary
manner, and on this spindle will be fastened or formed one or more cutters of
uniform or varying size, and having regular or irregular teeth, the said cutter or
cutters being fixed on the said spindle either at right angles thereto or at an angle
thereto greater or less than a right angle.
A table with moveable jaws will be employed, in which the substance under
operation will be firmly held, the said table having a horizontal reciprocating
motion, or a horizontal reciprocating and transverse motion, or a horizontal recipro-
cating transverse and undulating motion, the said motion or motions being derived
through an arrangement of shafts and cranks, or shafts and eccentrics, from the
first motion shaft of the apparatus, or otherwise.
The undulating or vertical reciprocating motion of the table can be replaced by
a vertical reciprocating motion of the bearings carrying the spindle and cutter,
this motion being governed by the hand or foot of the operator, or otherwise, and
can be produced by levers and cranks acting against a spring, or acting without a
spring, as desired, the apparatus being so formed and arranged as that the substance
under operation will be brought in contact with and cut by the rotating cutters,

page_text: and indentations made therein of irregular form and depth, so as to imitate the
indentations in real stag horn.
Instead of a moveable table, as above described, the substance under operation
can be brought in contact with the rotating cutter simply by the hand of the
operator.
The principles of this Invention can further be carried into effect by an apparatus
of the following description, that is to say:-A table with a moveable jaw will be
employed, in which the substance to be operated upon will be firmly held, and a
cutter or cutters, as above described, will be mounted on a spindle revolving in
bearings with handles that can be held by the operator.
The spindle and cutter will be rotated by a band or belt of an elastic substance,
so that varying pressure can be exerted by the operator, and deep or shallow
indentations made to imitate those in real stag horn.
The table will be fixed, or will revolve in fixed bearings at right angles or there-
abouts to the spindle and cutter, the said table being oscillated by levers and
cranks by the foot of the operator, or by levers and cranks from the line of shafting
driving the cutter and spindle, or otherwise, as desired.
One or more pieces of bone, wood, or other substance can be fixed in the table
of the apparatus at one time, and can be operated upon at the same time or in
succession, as desired.
By the above-described means and apparatus imitation or artificial stag horn
can be produced of a better quality, and cheaper, than has hitherto been accom-
plished.
