COMPLEIN DIUITICATION
A New or Improved Heating Box or Arrangement for Branding
Apparatus and other purposes.
'T, HENRY GILLOTT of 47 Rel Lion Street, Clerkenwell, in the County of Middlesex,
Stamp and Brand Maker, 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 :—
My invention relates to a new or improved machine for branding by the aid of
heat and a metallic devic, upon the flat surfaces of materials such as wood, leather
and the like..
In the machines hitherto made, and used for this purpose, by packing case makers,
trunk and portmanteau manufacturers and others, where a portion of the case, or
trunk is to furnished with a certain mark, brand or words, indeliably imprinted
and impressed thereon, it has been customary to apply the heat to the under surface
of the metallic device used, and place the substance to be branded thereon and apply
the necessary pressure upon the substance being treated, the result of this method
often leaves the material either burnt, or the impression blurred through overheating
My
the design, or through the substance being left on the heated design too long.
invention has for its object a method of and means for obviating this, and the manner
of constructing and operating the same to be ascertained in and by the following
statement.
In order that my invention may be clearly understood I have supplied a sheet.
of drawings appended hereunto, in which,
Fig. 1 is a front elevation of a complete machine according to my invention.
Figs. 2 and 3 are reverse end views, and Fig. 4 a back elevation, of the
same.
Fig. 5 is an enlarged and perspective view of the box or beat chamber carrying
the metallic device, and form the salient feature of my invention.
Fig. 5 is a vertical cross section of Fig. 5 taken centrally therethrough.
Fig. 7 is an end view of the metallic plate upon which the mark brand or lettering
is fixed.
Fig. 8 is an illustration of the manner adopted by me of utilizing my invention in
"branding
connection with portable or hand brands, more generally known as
irons."
Similar letters of reference are used to indicate corresponding parts throughout the
drawings.
In carrying out my invention I employ a stand, or table A, carrying a screw press
after the manner of those in general use and which forms no part of my present
invention. I construct a metallic box or chamber C, more particularly shewn by
Fig. 5 and by the sectional view Fig. 6. Said box or chamber is preferably rectangular
in plan and cross section the top or roof of which is of stouter metal than the ends
and provided with a central boss a in which revolves the flanged end of the screw b
of the press by which the box is raised and lowered. Upon each end of externally
I provide a vertical projection D which fits within a vertical slot E formed upon
the frame of the machine and in which it slides when C is raised or lowered by
the turning of the screw b. The bottom of C is of stout metal and has upon its
under surface a longitudinal dovetailed recess G extending the whole length thereof,
and into this is slided the plate Fig. 7 carrying upon its under surface the design.
mark or brand to be used. Within the chamber and extending from end to end
thereof and connected thereto, I provide a chimney or heat exhaust H which in cross
section may be described as semicircular or nearly so as shewn by the sectional view
Fig. 6 the upper or outlet end of which c occurs close to and under one of the

page_text: sides of the roof, the lower end branches in opposite directions across the width of C
and is connected to plates d and e at the sides of and brazed or otherwise attached to
the ends of C. The plates d and e being placed a suitable distance from the bottom
of C provides inlets F and F to the chimney H for purposes to be hereinafter more
fully described. Attached to the inner surface of the bottom of C, or integral therewith
1 arrange a central partition or draft divider I extending the whole length of C and
in close contact with the ends thereof and rising in a vertical direction for some
distance centrally and within the chimney H. It will be understood from the
description and illustration given by reference to the drawings that the chamber C
is absolutely without sides excepting those formed by the chimney H therefore I
find it necessary to interpose vertical supports J and J₁ between the roof and the
bottom of C in order that the rigidity thereof may be mained when under pressure.
When using coal gas for producing the necessary heat I arrange the pipes about the
chamber in any suitable manner but preferably as shewn by Figs. 1, 2, 3 and 4,
and by the dotted lines Fig. 5, so that the flame is derived from punctures or holes
made in that part of the pipe and f¹ which is attached to e and d at the upper part
of the openings F and F. To economise the consumption of gas I attach to the
supply pipe a Bunsen burner K of any suitable type as may be required.
The design, mark, or letters of which the brand is composed may be cast with or
upon the plate plate L or cut from metal and rivetted or screwed thereon as may be
required.
The machine according to my invention being constructed as described and shewn
the manner of operation is as follows, that is to say. The wood, leather or other
substance M to be branded is placed upon the table A and the plate L with the brand
intended to be used fixed thereon, is slid into the recess G, the gas is then lighted
at and the flame then impinges upon and keeps close to the inner surface of the
hottom of C in the manner shewn by Fig. 6 until obstructed by the plate I the object.
of which is to form a draught for both flames and the heat being exhausted
and the draught continued through H and out at c. When sufficient heat is imparted
to L the handle N is turned and the chamber thereby lowered until L presses upon M
and the brand effect when N is reversed and L leaves M which may remain and be
removed at will as the heat having been removed therefrom it cannot become burnt
or blurred unless the plate L be left thereon a longer time than necessary which would
le the fault of the operator and not the machine.
The arrangement of C and its accessories may be carried out upon any scale desired
and may with this in view arrange it so as to be used as an ordinary branding iron
in the manner shewn by Fig. 8 and obtain the necessary gas supply thereto in a
similar manner to that previously described.
Although I have described my invention as applicable to branding machines I may
adopt its use in the construction of cooking ovens where a top heat may be preferable
to a bottom heat, and by my method the fumes from the gas would be kept out of
the oven, and I may in either of my modifications or adaptations use as a source of
heat the gas produced by the vaporization of hydro carbon in any suitable manner
without departing from the principle of my invention.
I am aware that machines for branding purposes have hitherto been made and used,
but I am not aware that they have ever been arranged so as to provide a top heat to
the branding plate in the manner described and shewn by me, and while not laying
any claim to the construction of the frame of the machine.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is.
First-In an improved machine for branding and other purpose, the construction
and use of the box or chamber C as shewn, provided with recessed dovetailed bottom G
a dovetailed brand plate Lan internal partition or draft plate 1, chimney H, supported
by plates d and e forming the opening F and F the arrangement of the pipes f
and the manner of attaching them toe and d so as to impinge the flame upon G

page_text: substantially as and for the purposes herein described and shewn by the accompanying
drawings.
Second In an improved machine for branding and other purposes the application
and use of the several parts mentioned in the preceding claim arranged to be adapted
for use as a branding iron substantially as and for the purposes herein set forth and
shewn by Fig. 8 of the accompanying drawings.
Third The construction, use, and application of the; several parts described in the
first claim adapted for use in providing heat for cooking ovens and the like substantially
as herein described.
