IMPROVEMENTS IN SEWING MACHINES
Year: 1862

page_text: LETTERS PATENT to John Henry Glew, of Howland Street, Fitzroy
Square, in the County of Middlesex, for the Invention of "IMPROVEMENTS
IN SEWING MACHINES."
Sealed the 5th December 1862, and dated the 13th June 1862.
PROVISIONAL SPECIFICATION left by the said John Henry Glew at the
Office of the Commissioners of Patents, with his Petition, on the 13th
June 1862.
I, JOHN HENRY GLEW, of Howland Street, Fitzroy Square, in the County of
Middlesex, do hereby declare the nature of the said Invention for "IMPROVE-
MENTS IN SEWING MACHINES," to be as follows:-
This Invention relates to that description of sewing machines in which
two needles and two shuttles are employed, and consists in an improved
arrangement of placing the shuttles, òf employing a web or vertical plate in
the middle of the shuttle race, and in placing the eyes of the two needles in
different positions.
I place the shuttles face to face on each side of the web, by which means
two rows of stitching can be obtained much closer than by any other method,
the web being employed simply to form the guide or race for each shuttle.
The eye of one needle is at right angles with the shuttle race in the usual
manner, but the eye of the other needle is at or about an angle of 45° with
the shuttle race, and one needle is threaded at the front and the other at the

page_text: back, or in some descriptions of machines at opposite sides. The two needles
and shuttles are worked by one set of actuating parts, and can be applied to
any description of shuttle sewing machine.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John Henry Glew in the Great Seal Patent Office on the
12th December 1862.
-
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
HENRY GLEW, of Howland Street, Fitzroy Square, in the County of Middle-
sex, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirteenth day of June, in the year of our Lord
One thousand eight hundred and sixty-two, in the twenty-fifth year of
Her reign, did, for Herself, Her heirs, and successors, give and grant unto
me, the said John Henry. Glew Her. special licence that I; the said John
Henry Glew, my executors, administrators, and assigns, or such others as I, the
said John Henry Glew,, my executors, administrators, and assigns, should at
any time agree with, and no others, from time to time and at all times there-
after 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 "IMPROVE-
MENTS IN SEWING MACHINES," upon the condition (amongst others) that I,
the said John Henry Glew, my executors, or administrators, by. an instru-
ment in, writing under my, or their, or one of their hands and, seals, 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 John Henry Glew, 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:
This Invention relates to that description, of sewing machines: in, which, two,
needles and two shuttles, are, employed, and consists in an improved arrange-
ment of placing the shuttles and employing a, web or, vertical, plate. in, the
middle of the shuttle race.
t
I place the shuttles face to face on each side of the web, by, which, means

page_text: two rows of stitching can be obtained much closer than by any other
method, the web being employed to form part of the guide or race for each
shuttle.
These improvements will be clearly understood by referring to the figures
and letters on the accompanying Sheet of Drawings, in which Fig. 1 is a side
elevation of the principal parts of a sewing machine having my improvements
attached; and Fig. 2, a plan of the shuttles and shuttle race with the cover
removed.
a, b, represent the two needles; c, d, the two shuttles; e, the web or
vertical plate; f, g, the two shuttle races; and h the forked rod communi-
cating with the cam for giving the shuttles motion. The two needles and
shuttles are worked by one set of, actuating parts, and can be applied to any
kind of shuttle sewing machine, but in some descriptions of machines I find it
necessary, to place the eye of one of the needles at or about an angle of 45°
with the shuttle race, and one needle is threaded at the front and the other at
the back, or at opposite sides.
Having now described the nature and particulars of my said Invention, I
desire it to be understood that I claim in sewing machines the employment of
two shuttles face to face with a web or vertical plate between them, as such
improvements are herin described and illustrated in the accompanying Sheet
of Drawings.
In witness whereof, I, the said John Henry Glew, have hereunto set
my hand and seal, this Tenth day of December, in the year of our
Lord One thousand eight hundred and sixty-two.
Signed, sealed, and delivered by the
within-named John Henry Glew in the
presence of

Patent Agent,
London.
