COMPLETE SPECIFICATION.
An Improved Auto-calorific Branding Tool.
I, JAMES SIMCOE FITZMAURICE, of 26 Elizabeth Street, Sydney, in the
Colony of New South Wales, Electrical Engineer, 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 :-
This invention relates to an improved branding tool which is not only portable
but has within itself the power or means of producing the heat required for the
purpose of branding and of retaining for a comparatively very long time its stamp
device or brand constantly at such temperature. This improved tool is suitable for
branding in an economical effective and speedy manner all kinds of live and
inanimate subjects which are capable of being marked by hot-branding singeing or
burning but it is especially useful in branding live stock such as horses cattle sheep
pigs &c. by quick and certain action and easy manipulation.
This improved auto-calorific branding tool consists in the combination and arrange-
ment together in one instrument of two essential parts namely a symbol or symbols
or mark or brand of metal or other heat-conducting material and a lamp or burner
whose flame or jet will be in contact with or impinge upon the mark or brand and
these two essential parts are generally but not necessarily combined and arranged
with a reservoir or container from which will be supplied to the lamp or burner
inflammable liquid or gas from the oil or gas or other inflammable liquid fluid or
material easily gasified by heat in such reservoir or container.
In carrying this invention into effect it is preferred that the improved auto-
calorific branding tool should be constructed mainly as follows:-An annular vessel
or chamber or reservoir or container surrounds a tube on the end of which is fixed
the mark or brand. The annular reservoir has a smaller pipe leading therefrom
into the central tube. The heating of the tool is started by causing the contents
to gasify or vaporize by means of heat produced by burning cotton wick or soaked
The resultant
asbestos in the central tube or beneath the reservoir or container.
gas or vapor issues from a jet on the end of the smaller pipe in the central tube and
causes a draught of air therethrough and both issuing at the end mixed are lighted
and heat the brand and at the same time keep up the gasifying or vaporization of
the contents of the reservoir. The smaller pipe with its jet is provided with a
regulating valve the reservoir has a screw cap feeding hole and the central tube has
an air supply regulating device.
In a modified construction of this improved auto-calorific branding tool the
aunular container or reservoir may hold gas and the end of the central tube be
formed as a burner of the Bunsen type or the burner and the mark or brand may
be conveniently arranged together as a portable tool or instrument connected up to
a gas supply by means of a flexible pipe for convenience in handling.
In all constructions it is preferred that the brand or mark should have the side
nearest the flame or jet slightly hollowed so that said flame or jet will impinge
against said inner side and be confined in said hollow. In all cases too a convenient
and appropriate handle is fitted to the reservoir burner and brand being made of
heat non-conducting material and so formed that the brand when heated may be
easily applied to the subject.
But in order that this invention may be clearly understood reference will now be
made to the drawings herewith in which
Figure 1 is an end view showing a brand or symbol.
Figure 2 is a side view of same.
Figure 3 is an end view of handle end.

A metal (preferably copper) brand or symbol B (comprising a monogram
consisting of the letters E B C) is fixed to the end of a perforated casing or cap 1
preferably of sheet iron or material of less heat conductivity than the brand. This
perforated casing or cap forms the hollowed out portion of the brand hereinbefore
mentioned. Attached to the nose of the central tube A T of the annular reservoir
or vessel R (containing preferably methylated spirits) is clamp C having arms C¹
to which cap I is screwed. A is an asbestos guard or protector on burner end of
container R. In the tube is jet or pipe T having communication with interior of
vessel R at what must be regarded and used as its top and at the point of com-
munication is a regulating valve V whose screwed stem terminates in a wooden
vulcanite asbestos or other heat non-conducting knob or head W and which stem
passes through a stuffing box B' having a cover or gland G. The central tube A T
extends backwardly through a heat non-conducting handle H to an air supply
regulator consisting of a covered in sliding piece R₁ with an orifice the extent of
opening of which is regulated by said sliding piece R'. The wad torch or starter
Figure 5 consists of asbestos A¹ (which is soaked in spirits or oil) on a convenient
handle.
In use the container R is filled with oil or spirits (preferably the latter) to say
within half an inch of the top thereof and the top of jet or pipe T and the stuffing
box B carrying the valve V is tightly screwed into nut N. The starter or wad or
torch saturated with spirits is then ignited and applied under the reservoir R or
under nose of tube A T until the oil or spirit in such reservoir gasifies or vaporises
when valve V being opened the gas or vapor will issue from jet T and mixing with
the air may be ignited at the end of the central tube. Regulator R' may then be
slid outwardly to supply air for complete combustion which taking place the flame
thereof will impinge on the back of the brand and the resultant gases, &c. escape
through perforated cap I. While the brand B is being thus raised to the required
temperature the torch or wad A' is extinguished and the combustion in tube C
causes the further gasifying or vaporising of the oil or spirit in reservoir. The
flame in such tube is regulated by the valve V and the slide R¹ the former
controlling the consumption of oil or spirit and the latter the supply of air. The
brand being thus auto-calorified may be used as ordinarily in branding live and
inanimate subjects being supplied with oil or spirits as required through nut N.
It is to be understood that this invention is not confined to any special form of
lamp or burner to any particular form or design of brand or mark nor to any
particular or special heating agent so long as the nature and scope of that which
has been hereinbefore described is not departed from.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is
First. An improved auto-calorific branding tool consisting essentially of the
combination and arrangement in one instrument with a symbol or symbols or mark
or brand capable of being heated of a lamp or burner whose flame or jet will
impinge upon said symbol or mark or brand substantially as herein described and
explained.
Second. An improved auto-calorific branding tool consisting of the combination
and arrangement in one instrument with a mark or brand capable of being heated
and a lamp or burner whose flame or jet will impinge upon said mark or brand of a
reservoir or container for gas or for fluid or material easily gasified by heat sub-
stantially as herein described and explained.
Third. An improved auto-calorific branding tool consisting of an annular vessel
or reservoir whose central tube carries on one end a brand or mark and in it a pipe
or jet in communication with said reservoir and of means for regulating the
admission of gas to said pipe or jet and for regulating the admission of air to said
central tube substantially as herein described and explained.

page_text: Fourth. An improved auto-calorific branding tool consisting of the combination
and arrangement together of mechanical parts substantially as herein described and
explained and as illustrated in the drawings.
