County of Middlesex Gentleman do hereby declare the nature of my invention
for "IMPROVEMENTS IN PENS FOR DRAWING PICTURES ORNAMENTAL AND OTHER
DESIGNS ON GLASS OR OTHER SURFACES" A Communication to me from abroad

This Invention relates to improvements in the construction of pens for drawing
pictures ornamental and other designs on glass or other surfaces as described in
the Specification of Letters Patent granted to John Henry Johnson dated 9th May
1881 No 2016.
This improved pen consists of an ordinary steel writing pen mounted in a metal
socket inserted in a suitable holder advantageously wood. A reservoir (for
retaining a supply of ink when the pen is dipped into a vessel containing it) is
formed by a hollow tubular pointed finger or instrument arranged within the
hollow of the nib or pen.
The pen is kept hot by means of a jet of gas passing through the holder to a
small pipe so bent as to cause the jet of gas to impinge upon the pen and thus
keep the lithographic, or other suitable ink sufficiently fluid to flow to the point of
the pen.
.
Air may be admitted to the gas burner so that a mixture of gas and air may
be burnt to impart heat to the pen on the principle of the Bunsen burner by
which any accumulation of carbon resulting from the combustion of gas alone is
prevented.

This invention is also applicable to the heating of a ruling pen and bow pen or
compass for ruling lines and making circles for mechanical or architectural or other
like drawings.

I WILLIAM HENRY DALTON Junior at present of 118 Gower Street in the
County of Middlesex Gentleman do hereby declare the nature of my invention
for "IMPROVEMENTS IN PENS FOR DRAWING PICTURES ORNAMENTAL AND OTHER
DESIGNS ON GLASS OR OTHER SURFACES' A communication to me from abroad
by Samuel Henry Crocker of "The Patent Engraving Company" of Metropolitan
Chambers Collins Street Melbourne Victoria Australia 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 improvements in the construction of pens for drawing
pictures ornamental and other designs on glass or other surfaces as described in
the Specification of Letters Patent granted to John Henry Johnson dated 9th May
1881 N° 2016.
And in order that my invention may be clearly understood I will proceed to
describe the same with reference to the drawing annexed.
This improved pen consists of an ordinary steel writing pen or nib a mounted in
a metal socket.al inserted in a suitable holder b advantageously wood. A reservoir
(for retaining a supply of ink when the n is dipped into a vessel containing it)
is formed by a hollow tubular pointed tir
hollow of the nib or pen.
.The .pen. is kept bot by means of a jet e
small pipe d' so bent as to cause the jet of
keep the lithographic or other suitable in
the pen.
or instrument c arranged within the
gas d passing through the holder to a
as to impinge upon the pen and thus
ufficiently fluid to flow to the point of
Air may be admitted to the gas burner d through perforations at d* or at any
other suitable part of the gas supply pipe d' so that a mixture of gas and air may
be burnt to impart heat to the pen on the principle of the Bunsen burner by
which any accumulation of carbon resulting from the combustion of gas alone is
prevented. d² is a flexible pipe to connect the pipe d to the gas supply pipe.
This Invention is also applicable to the heating of a ruling pen and bow pen
or compass for ruling lines and making circles.for mechanical or architectural or
other like drawings by lithographic transfer or other similar means.
Having now particularly described and ascertained the nature of the said
Invention and in what manuer the same is to be performed I declare that what
I claim is
The improved arrangement and construction of pens having heat applied thereto
for drawing upon glass or other surfaces for engraving thereon substantially as and
for the purpose herein before described and represented in the drawing annexed.
Dated this 22nd day of November 1884.
