PROVISIONAL SPECIFICATION left by the said Richard Archibald
Brooman at the Office of the Commissioners of Patents, with his
Petition, on the 28th September 1865.
I, RICHARD ARCHIBALD BROOMAN, of 166, Fleet Street, in the City of
London, Patent Agent, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN SEWING MACHINES," to be as follows:-
These improvements in sewing machines consist-First, in the employment
of a spring on the needle bar for the purpose of holding the thread tight
above the needle while the needle is rising in its work; second, in the
emyloyment of a needle guide in the form of a bent bar with an eye through
which the needle passes, for the purpose of giving stability to the needle,
especially when working in leather and other heavy goods; and third, in
the employment of a spring on the presser foot shaft in addition to the
[Price 8d]

page_text: ordinary spiral spring, which spring is connected to the needle bar, and is
operated by it to ensure the holding or forcing down of the presser foot
while the needle is in the work.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Richard Archibald Brooman in the Great Seal Patent
Office on the 28th March 1866.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, RICHARD
AROHIBALD BROOMAN, of 166, Fleet Street, in the City of London, Patent
Agent, send greeting.
of our
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters,
Patent, bearing date the Twenty-eighth day of September, in the year
Lord One thousand eight hundred and sixty-five, in the twenty-ninth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
me,the said Richard Archibald Brooman, Her special licence that I, the said
Richard Archibald Brooman, my executors, administrators, and assigns, or
such others as I, the said Richard Archibald Brooman, 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 SEWING MACHINES,"
(communicated to me from abroad by John Nathaniel Tarbox, of Hamilton,
Canada West,) upon the condition (amongst others) that I, the said Richard
Archibald Brooman, my executors or administrators, by an instrument in
writing under my, or their, or one of their hands and seals, should par-
ticularly 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 imme-
diately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Richard Archibald Brooman, do
hereby declare the nature of the said Invention, and in what manner the
same is to be performed, to be particularly described and ascertained in and
by the following statement thereof, reference being had to the Drawings
hereunto annexed, that is to say:-
These improvements in sewing machines consist, first, in the employment
of a spring on the needle bar for the purpose of holding the thread tight
above the needle while the needle is rising in its work.

page_text: Figure 1 of the accompanying Drawings represents the head of a sewing
machine with this improvement applied thereto. a is the head, and 6 the
needle bar; c is a spring fixed at its upper end to the bar b, the lower end
of this spring is formed with an aperture through which the thread passes
on its way to the needle. The spring c is shaped so that its lower end
presses against the lower end of the barb, or against the needle tightening
screw d, and thereby holds the thread tight above the needle while the needle
is rising in its work.
The improvements consist, secondly, in the employment of a needle guide
in the form of a bent bar with an eye through which the needle passes, for
the purpose of giving stability to the needle, especially when working in
leather and other heavy goods.
This improvement is represented in Figure 2. a is the head of a sewing
machine, and 6 is a bent bar secured to the under side of the head by a
screw c. The bar 6 is formed with an eye through which the needle passes,
and thereby receives stability when working. The bar 6 is placed a sufficient
height from the work plate to prevent its interfering with the movements
of the presser foot.
The improvements consist, thirdly, in the employment of a spring on the
presser foot shaft in addition to the ordinary spiral spring, which spring is
connected to the needle bar, and is operated by it to ensure the holding or
forcing down of the presser foot while the needle is in the work.
This improvement is represented in Figure 3. a is the presser foot shaft,
and 6 the needle bar; c is a spring connected at one end to the bar b, while
the other end presses upon the head of the presser foot shaft a. When the
needle bar 6 is descending the spring c is operated thereby, and ensures
the holding or forcing down of the presser foot while the needle is in the
work.
And having now described the nature of the said Invention, and in what
manuer the same is to be performed, I declare that I claim as the " Improve-
ments in Sewing Machines
"
First, the employment of a spring on the needle bar for the purpose of
holding the thread tight above the needle while the needle is rising in its
work, substantially as herein-before described and represented in Figure 1
of the accompanying Drawings.
Second, the employment of a needle guide in the form of a bent bar with
au eye through which the needle passes, substantially as and for the purpose
herein-before described and represented in Figure 2 of the accompanying
Drawings.

page_text: Third, the employment of a spring in addition to the ordinary spiral spring,
in order to ensure the holding or forcing down of the presser foot while the
needle is in the work,substantially as herein-before described and represented
in Figure 3 of the accompanying Drawings.
In witness whereof, I, the said Richard Archibald Brooman, have here-
unto set my hand and seal, this Twenty-seventh day of March, One
thousand eight hundred and sixty-six.
R. A. BROOMAN. (L.S.)
