Improvements in Cattle Branding Apparatus.
Messrs. WOODHOUSE & RAWSON UNITED LIMITED Electric Engineers and
Contractors, 88 Queen Victoria Street London, E.C. do hereby declare the nature
of this invention to be as follows:-
The object of this invention is to facilitate the branding of cattle and the like
operations, and for this purpose we make use of an instrument in which the letters
or designs to be used are formed of suitable conducting material and brought to the
requisite heat by the passage of a current of electricity the portions forming the
design being a part of the circuit. To enable the design to be changed, we may
use detachable sections somewhat in the form of staples, the two ends being clamped
in suitable terminals. We provide such insulation as may be necessary and a
convenient handle or handles and in some cases we may arrange an automatic
switch in the handle so that the pressure thereon in using the instrument shall
complete the circuit, or by an alternative arrangement the grip on the handle may
be arranged to turn on or off the circuit at will. An adjustable resistance may be
included in the circuit and a measuring instrument or incandescent lamp may be
added so as to indicate when the current is of the requisite strength.
Dated this Eleventh day of December 1890.

COMPLETE SPECIFICATION.
Improvements in Cattle Branding Apparatus.
WOODHOUSE AND RAWSON UNITED LIMITED, Electrical Engineers and
Contractors, of 88 Queen Victoria Street, London, E.C. do. hereby declare the
nature of this invention and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :-
The object of this invention is to facilitate the branding of cattle and the like
operations, and for this purpose, we make use of an instrument in which the letters
or designs to be used are formed of suitable conducting material and brought to the
requisite heat by the passage of a current of electricity; the portions forming the
design being part of the circuit.
Referring to the accompanying drawing
Fig. I. The slab A consists of any suitable insulating non-combustible material,
such as asbestos porcelain etc. through which is threaded an electrical conductor E
of suitable section and substance preferably of iron, to any design in the form of
letters or otherwise as may be desired, that portion of the conductor which is
embedded in and at the back of the slab A, is thickened by bending the conductor
back on itself or if we think fit, we insert at the back another metal of greater
conductivity so as to reduce the heating.
To facilitate the change of design, we may form our conductor of pieces
somewhat like staples F Fig. I having square heads, which are clamped to the
back of the slab A with suitable nuts and connections, shown at H Figs. I and III.
We mount the whole slab of insulating material with the conductors woven
through, in a suitable case or box B Fig. III attached to a handle C carrying a
D

page_text: switch D, which may be worked intermittently by the grip of the hand, as required,
to obviate the waste of current, and wear and tear to the design when not actually
in use, and terminals G for connection to the source of power. An adjustable
resistance J may be included in the circuit, or mounted on the instrument, to
regulate the strength of the current.
Having now particularly described the nature of this invention, what we claim is,
I. An instrument for branding designs and the like by means of electrically
produced heat, substantially as described and for the purposes set forth.
II. In an electrical branding instrument the formation of the design in separate
pieces of conducting material suitably jointed together, substantially as described,
and for the purposes set forth.
