IMPROVEMENTS IN SEWING MACHINES
Year: 1872

page_text: LETTERS PATENT to Newton Wilson, Engineer and Manufacturer of
Sewing Machines, of 144, High Holborn, in the County of Middle-
sex, for the Invention of "IMPROVEMENTS IN SEWING MACHINES."
Sealed the 15th April 1873, and dated the 16th October 1872.
PROVISIONAL SPECIFICATION left by the said Newton Wilson at the
Office of the Commissioners of Patents, with his Petition, on the
16th October 1872.
I, NEWTON WILSON, Engineer and Manufacturer of Sewing Machines,
of 144, High Holborn, in the County of Middlesex, do hereby declare the
nature of the said Invention for "IMPROVEMENTS IN SEWING MACHINES,"
to be as follows :-
My Invention consists in a new arrangement for giving vertical motion
to a straight needle without the intervention of the usual needle slide,
and which I accomplish by an eccentric placed upon the horizontal

page_text: shaft, giving in its rotary motion the downward throw to the needle arm,
which traverses in a slot immediately over the eccentric. This needle
arm has a bracket projecting at right angles below the shaft. After
receiving its downward motion the upward action is given by a spring
attached to the base of the machine and pressing on the under side
of the bracket before described. The spring further answers the pur-
pose of balancing the weight of the arm, thus making the motion
smoother and diminishing the friction. This arrangement is designed
to operate in conjunction with a revolving looper for securing the loop
formed by the needle, and the whole is driven by the system of internal
gear patented by me on the 14th of February 1866.
The objects chiefly sought in this Invention are cheapness, simplicity,
and portability, the latter being still further secured by an arrangement
of the driving handle by means of a bracket and screw, so as to place
it without removal in a pendant position when not in use.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Newton Wilson in the Great Seal Patent Office
on the 16th April 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, NEWTON
WILSON, Engineer and Manufacturer of Sewing Machines, of 1·14,
High Holborn, in the County of Middlesex, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent; bearing date the Sixteenth day of October, in the
year of our Lord One thousand eight hundred and seventy-two, in the
thirty-sixth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Newton Wilson, Her special
licence that I, the said Newton Wilson, my executors, administra-
tors, and assigns, or such others as I, the said Newton Wilson, 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

page_text: IN SEWING MACHINES," upon the condition (amongst others) that I, the
said Newton Wilson, 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 Newton Wilson, 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:-
My Invention consists in a new arrangement for giving vertical
motion to a straight needle without the intervention of the usual
needle slide, which I accomplish by an eccentric placed upon the
horizontal shaft giving in its rotary motion the downward throw to the
needle arm which traverses in a slot immediately over the eccentric.
This needle arm has a bracket or brackets projecting at right angles
below the shaft. After receiving its downward motion the upward
motion is given by a spring attached to the base of the machine and
pressing on the under side of the bracket before described, or as I
generally prefer, by a second bracket immediately above the said eccen-
tric acting in connexion with the spring which works just above it.
The spring further answers the purpose of balancing the weight of the
arm, thus making the motion smoother and diminishing the friction.
This arrangement is designed to operate in conjunction with a rotary
looper for securing the loop formed by the needle, and the whole is
driven by the system of internal gear patented by me on the Fourteenth
of February, One thousand eight hundred and sixty-six, No. 475.
The objects chiefly sought in this Invention are cheapness, simplicity,
and portability, the latter being still further secured by an arrangement
of the driving handle by means of a bracket and screw, so as to place it
without removal in a pendant position when not in use.
In compliance with the said condition in the said Letters Patent con-
tained, thus far, I have particularly described and ascertained the nature
of the said Invention, and have incidentally in general terms described
in what manner the same is to be performed or put in practice. Now

page_text: in further compliance with the said condition I proceed to fully and
particularly describe and ascertain in what manner my said Invention
is to be performed or put in practice by referring to the Drawings
accompanying this Specification, the description whereof is to be read
in conjunction with the herein-before contained descriptive statements {
Figure 1, view of a sewing machine constructed in accordance with
my said Invention; Figure 2, back view of slide arrangement; Figure 3,
end view of same; Figure 4, view shewing the arrangement of the
driving handle; Figure 5, view of cap and spring; Figure 6, detached
view of rotary looper in connection with the feed arrangement.
In these Figures a denotes the eccentric placed on the horizontal
shaft b so as to give the herein-before described motion to the needle
arm c traversing in slot d. The projecting brackets for the needle arm are
marked e and e", and ƒ denotes the spring which I prefer to use, as
shown in the Drawing, for balancing the weight of the needle arm. In
the downward throw of the needle the spindle m passes through the
slot formed by the projecting lugs n, n, on the cap o, while the spring is
compressed against the projecting lugs; g denotes the rotary looper for
securing the loop formed by the needle; h denotes the driving wheel
'constructed on the internal gear system patented by me as aforesaid.
The upper bracket e* is made adjustable by means of screw and slot x,
ás shewn in the Drawing; i denotes the handle which is attached to a
projecting bracket k, secured to the side of the driving wheel by the
thumbscrew, and as this bracket is secured in a recessed part of the
driving wheel, when slackened the handle falls into the pendant position
shewn by the dotted lines. The needle plate is marked p, the base
plate q, the fixed arm 7, and the feet, which are of india-rubber, 8;
t being the bobbin peg.
Having now particularly described and ascertained the nature and
objects of the said Invention, and in what manner the same is to be
performed or put in practice, I hereby declare that I claim the said
Invention of "Improvements in Sewing Machines," the nature and
character whereof is herein-before described and illustrated by the
Drawings accompanying this Specification, it being understood that I

page_text: do not limit myself to the exact details exhibited by the said Drawings
and herein described.
In witness whereof, I, the said Newton Wilson, have hereunto
set my hand and seal, this Sixteenth day of April, in the
year of our Lord One thousand eight hundred and seventy-three.
NEWTON WILSON. (L.S.)
