IMPROVEMENTS IN CONNECTION WITH SEWING AND OTHER MACHINES
Year: 1865

page_text: LETTERS PATENT to Henry Masters, of the City and County of Bristol,
Architect, for the Invention of "IMPROVEMENTS IN CONNECTION WITH SEWING
AND OTHER MACHINES."
Sealed the 28th July 1865, and dated the 7th February 1865.
PROVISIONAL SPECIFICATION left by the said Henry Masters at the
Office of the Commissioners of Patents, with his Petition, on the 7th
February 1865.
I, HENRY MASTERS, of the City and County of Bristol, Architect, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN CONNECTION
WITH SEWING AND OTHER MACHINES," to be as follows:-
And consists in the use of two or more rollers attached to or connected
with a foot pedal, the said rollers acting or pressing upon straps, cords, or
bands, by means of which a spindle may be set in motion, and the velocity
ratio may be varied and controlled. The action of the foot upon the pedal
(which is provided with a balance weight) causes the rollers to press on or
against the strap, cord, or band, and produces tightness, thereby setting the
spindle in motion, and, upon lifting the foot, the band, cord, or strap will be

page_text: loosened (by the action of the balance weight) and the spindle become dis-
engaged. The result practically is, that by pressing lightly upon the pedal a
slow velocity will be imparted to the spindle, and by pressing heavily a more
rapid velocity will be obtained.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Henry Masters in the Great Seal Patent Office on the
3rd August 1865.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HENRY
MASTERS, of the City and County of Bristol, Architect, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Seventh day of February, in the year of our Lord
One thousand eight hundred and sixty-five, in the
year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Henry Masters, Her special licence that I, the said Henry Masters,
my executors, administrators, and assigns, or such others as I, the said
Henry Masters, 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 "Ix-
PROVEMENTS IN CONNECTION WITH SEWING. AND OTHER MACHINES," upon the
condition (amongst others) that I, the said Henry Masters, my executors or
administrators, by an instrument 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 Henry Masters, 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:-
This Invention consists in the use of two or more rollers attached to or
connected with a pedal or lever, such rollers acting or pressing upon straps,
cords, or bands, by means of which a spindle may be set in motion, and
the velocity ratio may be varied, and which is more particularly described by
reference to the annexed Drawings, in which D is a driving wheel set in

page_text: motion by any suitable means; S, a spindle, required to be set in motion by
or disengaged from D. The red lines are endless straps, cords, or bands. P is
a pedal or lever; W, a counterbalance weight; F, rollers or wheels. The
action when the pedal or lever is pressed causes the rollers to press the strap,
cord, or band, which produces tightness, thereby setting the spindle S in motion,
& upon removing the pressure the weight W will cause the strap, cord, or
band to loosen, and the spindle S will become disengaged. The result
practically is, that by pressing lightly upon the pedal or lever a slow velocity
will be imparted to the spindle, & by pressing heavily thereon, a more
rapid velocity.
Witness to the signature of
the said Henry Masters,
