CERTAIN IMPROVEMENTS IN THE MANUFACTURE OF 'SPECIES JARS' OR SHOW JARS
Year: 1853

page_text: LETTERS PATENT to Matthew Tomlinson, of Hulme, Manchester,
in the County of Lancaster, Druggists' Sundries Merchant, for the
Invention of CERTAIN IMPROVEMENTS IN THE MANUFACTURE OF
'SPECIES JARS' OR SHOW JARS."
Sealed the 1st July 1858, and dated the 1st January 1853.
PROVISIONAL SPECIFICATION left by the said Matthew Tomlinson
at the Office of the Commissioners of Patents, with his Petition,
on the 1st January 1853.
I, MATTHEW TOMLINSON, of Hulme, Manchester, in the County of
Lancaster, Druggists' Sundries Merchant, do hereby declare the nature
of my said Invention of "CERTAIN IMPROVEMENTS IN THE MANUFACTURE
SPECIES JARS' OR SHOW JARS" to be as follows:-
OF
My improvements relate to the manufacture of "species jars" or
show jars used for ornamenting druggists' shop windows and for other
similar purposes.
It has hitherto been the practice to manufacture such jars from flint

page_text: glass by the ordinary process of manufacturing flint glass bottles; and
as such jars so manufactured (more especially the larger and conse-
quently the more costly sizes) are extremely liable to crack and become
broken after the process of gilding and ornamenting is completed, great
risk and loss is thereby incurred.
My Invention consists in manufacturing the cylinders or bodies of
species jars" or show jars from "sheet window glass," by the method
or process commonly employed in manufacturing such glass into shades,
and completing the same by the addition of a neck and shoulder, so as
to assume the form or appearance of the "species jars" or show jars
usually employed as before mentioned for ornamenting shop windows,
and for other similar purposes, which cylinders so manufactured have
not been hitherto so adapted or employed, and which new adaptation or
method of manufacture effects a great.improvement, and possesses many
advantages over the method hitherto employed in manufacturing such
jars from flint glass, as the jars manufactured according to my Inven-
tion from sheet window glass" are much more even in surface and
more uniform in shape than those manufactured by the ordinary process
from flint glass, and are capable. of being manufactured of much
larger dimensions, without the liability or risk of their becoming cracked
or broken as before mentioned.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Matthew Tomlinson in the Great Seal Patent
Office, on the 1st July 1853.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I,
MATTHEW TOMLINSON, of Hulme, Manchester, in the County of Lan-
caster, Druggists' Sundries Merchant, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the First day of January, in the year
of our Lord One thousand eight hundred and fifty-three, in the six-

page_text: teenth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Matthew Tomlinson, Her special
license that I, the said Matthew Tomlinson, my executors, adminis-
trators, and assigns, or such others as I, the said Matthew Tomlin-
son, 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 "CER-
TAIN IMPROVEMENTS IN THE MANUFACTURE OF SPECIES JARS' OR 'SHOW
JARS,'"
upon the condition, amongst others that I, the said Matthew
Tomlinson, by an instrument in writing under my hand and seal, and
should particularly describe and ascertain the nature of the said In-
vention, 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 Matthew Tomlinson, do hereby.
declare the nature of my said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and
by the following statement (that is to say):
My improvements relate to the manufacture of certain kinds of glass
jars of a cylindrical form, such as are commonly called or known as
"species jars or show jars," and which are ordinarily used or employed
for the ornamentation or decoration of druggists' and other shops and
windows, and for other purposes, both ornamental and useful. In order
more clearly to set forth and describe the nature and object of my said
Invention of certain improvements in the manufacture of "species jars "
or "show jars," together with the manner of carrying the same into
practical effect, I consider it necessary or advisable here to state that
it has hitherto been, to the best of my knowledge and belief, the
invariable practise to manufacture such "species jars" or "show jars"
exclusively from flint glass, by the common or ordinary and well known
process as employed for manufacturing flint glass bottles and other
similar articles formed from flint glass. But it has been found by ex-

page_text: perience that such ("species jars" or "show jars" so manufactured,
more especially the larger and consequently the more costly sizes,) are
extremely liable to crack and become broken after the process of gild-
ing and otherwise ornamenting them is completed, and great and
serious risk and loss is thereby occasioned. My Invention is intended
to obviate this liability, and consists in manufacturing the cylinders or
bodies of such species jars" or "show jars" from what is commonly
called "sheet window glass" (by the ordinary method of process com-
monly employed in manufacturing such glass into shades), and complet-
ing the same by the addition of a shoulder and neck, so as to cause
them to assume the form or appearance of the said "species jars" or
"show jars," usually employed as before mentioned for the ornamenta-
tion or decoration of druggists' and other shops and windows, and for
other useful and ornamental purposes. Which said cylinders formed of
sheet window glass so manufactured have not hitherto been so adapted
or employed to the best of my knowledge and belief, and which new
adaptation or method of manufacture effects a great improvement in
the said "species jars or "show jars," and possesses many advantages
over the ordinary method hitherto employed of manufacturing such jars
from flint glass, as the " specios jars" or "show jars" manufactured
according to my Invention from sheet window glass as above described
are very much more even and regular in surface, and more uniform in
thickness and in shape or configuration, than those hitherto manufac
tured by the ordinary process from flint glass; and such "species jars
or "show jars" are capable of being manufactured of much larger
dimensions than formerly, owing to their uniformity in thickness, with-
out the same liability or risk of their being cracked or broken; either
luring or after the process of gilding, or otherwise ornamenting the
same as before mentioned.
Having thus described and set forth the nature and objects of my
said improvements in the manufacture of "species jars" or "show jars,
together with the manner of carrying the same into practical effect,
would remark, in conclusion, that I claim as my Invention the manufac
turing such species jars" or "show jars" from what is commonly

page_text: termed "sheet window glass," as above described, instead of manufac-
turing such jars from flint glass as hitherto ordinarily practised.
In witness whereof, I, the said Matthew Tomlinson, have hereunto
set my hand and seal, this Twenty-ninth day of June, in the
year of our Lord One thousand eight hundred and fifty-three.
MATTHEW TOMLINSON. (L.S.)
