Year: 1855

page_text: LETTERS PATENT to Henry Bach, of Sheffield, in the County of York,
Hosier, for the Invention of "IMPROVEMENTS IN SASH FRAMES."
PROVISIONAL SPECIFICATION left by the said Henry Bach at the
Office of the Commissioners of Patents, with his Petition, on the 15th
March 1855.
I, HENRY BACH, of Sheffield, in the County of York, Hosier, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN SASH FRAMES,"
to be as follows:-
My Invention consists in the application to such purpose of hollow glass
pillars or facings, gilded on the back or inner surface, so as to represent brass
rods or pillars, or ornamented with colours on the back. The back or inner
surface of the glass pillar or facing is made semicircular or otherwise, in order
to fit against and cover a lining of wood or other suitable material which is
concealed by the coating of gold or colouring matter on the back or inner
surface of the said pillar or facing. If preferred, the gilding or colouring
intended to appear through the glass pillar or facing from behind the same
may be separate therefrom, instead of forming a coating on the inner surface
thereof. The outer surface of the pillar or facing may be semicircular or
otherwise formed, as preferred, but the pillar or facing should be made of
such thickness as is best adapted for producing the effect desired.

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HENRY
BACI, of Sheffield, in the County of York, Hosier, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fifteenth day of March;-in-the--year-of our Lord
One thousand eight hundred and fifty-five, in the eighteenth year of Her

the said Henry Bach, Her special license that I, the said Henry Bach, my
executors, administrators, and--assigns,--or--such-others as I, the said Henry
Bach, my executors, administrators, and assigns, should at any time agree
with, and no others, from time to time and at all times thereafter during the
term therein expressed, should and lawfully might make, use, exercise; and
vend, within the United Kingdom of Great Britain and Ireland, the Channel
Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN SASHI FRAMES,"
upon the condition (amongst others) that I, the said Henry Bach, by an instru-
ment in writing under my hand and seal, should particularly describe and
ascertain the nature of the said Invention, and in what manner the same was
to be performed, and cause the same to-be filed in the Great Seal Patent
Office within six calendar months next and immediately after the date of the
said Letters Patent.
.....
NOW KNOW YE that I, the said Henry Bach, do hereby declare the
nature of my said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement (that is to say):-
:
My Invention of "Improvements in Sash Frames" consists in the applica-
tion to such purpose of hollow glass pillars or facings, gilded on the back or
inner surface, so as to represent brass rods or pillars, or ornamented with colours
on the back. The back or inner surface of the glass pillar or facing is made semi-
circular or otherwise, in order to fit against and cover a lining of wood or other
suitable material which is concealed by the coating of gold or colouring matter
on the back or inner surface of the said pillar or facing. If preferred, the gilding
or colouring intended to appear through the glass pillar or facing from behind
the same may be separate therefrom, instead of forming a coating on the inner
surface thereof. The outer surface of the pillar or facing may be semicircular
or otherwise formed, as preferred, but the pillar or facing should be made of
such thickness as is best adapted for producing the effect desired.

page_text: This pillar or facing may be manufactured in the following manner, but I
do not confine myself to such mode or modes of manufacture:-I make a
mould such as is ordinarily used in casting glass of any desired length and
form in the cross section, say, eight feet long, and semicircular in the cross
section, and in this mould I cast the pillar or facing of the required length
and form. I also produce a similar result by bending a sheet of plate glass of
suitable dimensions over a mould or core of the form required for the back or
inner surface of the pillar or facing. I then grind or polish the outer and inner
surfaces of the pillar or facing thus produced, if required, which is intended
to be fitted to the sash bar composed of wood or other suitable material.
The glass pillar or facing is then gilded or coloured on the back or inner
surface if intended to be applied to a plain or unornamented sash bar; or the
gilding or colouring may be dispensed with if the pillar or facing be intended
to be applied to an ornamented sash bar; or the ornamenting of the surfaces
may be partly on the back of the pillar or facing, and partly on the sash bar.
The glass pillar or facing thus prepared is secured to the sash bar by means of
a fastening within the glass, or by means of a metal clasp for the glass to rest
upon; but I do not confine myself to such modes of securing the glass to
the bar.
Having thus described the nature of my Invention, and the manner in
which the same is to be performed, I would have it understood that I do not
claim as of my Invention the glass pillar or facing above described, otherwise
than as applied to the facing or covering of sash frames; neither do I claim
the sash bar above referred to, otherwise than as covered by the glass pillar or
facing, above described. But what I do claim as of my Invention is, the glass
pillar or facing adapted and applied to the covering or ornamenting of the sash
frame for the purpose described.
In witness whereof, I, the said Henry Bach, have hereunto set my hand
and seal, the Thirteenth day of September, in the year of our Lord One
thousand eight hundred and fifty-five.
Witness,
SAM HILL SMITH,
Sheffield.
HENRY BACH. (L.S.)
