IMPROVEMENTS IN SEWING MACHINES
Year: 1871

page_text: LETTERS PATENT to Newton Wilson, of 144, High Holborn, in the
County of Middlesex, Sewing Machine Manufacturer, for the
Invention of "IMPROVEMENTS IN SEWING MACHINES."
Sealed the 3rd April 1872, and dated the 5th October 1871.
PROVISIONAL SPECIFICATION left by the said Newton Wilson at the
Office of the Commissioners of Patents, with his Petition, on the
5th October 1871.
I, NEWTON WILSON, of 144, High Holborn, in the County of Middlesex,
Sewing Machine Manufacturer, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN SEWING MACHINES," to be as follows:-
Firstly. In giving a vibrating action to the presser foot by causing
the needle cam in its descent to operate on a small lever attached to the
presser slide, and so arranged as to be thrown in or out of action at the
pleasure of the operator during the working of the machine.

page_text: Secondly. In reducing the noise incidental to a shuttle machine by
introducing leather or similar non-conducting material into the recess for
the driver near the point of the shuttle.
Thirdly. In the application of a new arrangement of embroidering
apparatus to connect with the presser slide, and which consists of a
separate foot with an extended arm to which is attached a ratchet
motion operated from a stud in the needle bar, and which stud working
in a slot of the lever gives the requisite traversing motion to two bent
levers which carry the different embroidering materials intended to
be used.
Fourthly. In a new mode of obtaining an ornamental zig-zag. or
herring-bone stitch, and which is accomplished as follows:-A pinion is
cut in or placed upon the feed shaft below the shuttle race; this is made
to drive by a small pinion a concave disc. A stud connected with the
feed bar works against the bevilled sides of this disc, and is made to
communicate from it the requisite stepping motion to the feed bar.
By raising or depressing the stud and causing it thus to operate nearer
to or further from the centre of the disc, or more correctly higher up or
lower down its incline, the breadth of the step is regulated at pleasure.
In this arrangement the disc is made to travel at half the speed of the
feed shaft.
Fifthly. In another mode of obtaining this stitch by cutting in the
periphery of the feed cam two narrow parallel grooves which intersect
each other at one point. A stud as in the other arrangement is fixed in
the lower part of the feed bar, but in this case is diamond shaped, and
which traversing one of these grooves crosses to the other at the point of
intersection, and so communicates a stepping or lateral movement to the
feed. The movement is made adjustable either by splitting this cam iu
the centre of the midfeather, and by a screw at the end of the shaft
withdrawing the outer half to the extent desired, or it is effected by
hinging the lower or projecting bracket to the upper part of the feed
bar, and then by a long thumbscrew fitted to the needle plate, and
pressing against the side and near the upper edge of the feed bar itself,
to regulate the outstepping movement of the feed.
Sixthly. By either of the preceding arrangements having obtained

double action to the feed, so that when one side of the button-hole is
completed, the movement of a finger lever shall reverse the motion of
the work, and so stitch down the other side, without in any way moving
or disturbing tho work.

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, NEWTON
WILSON, of 144, High Holborn, in the County of Middlesex, Sewing
Machine Manufacturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fifth day of October, in the year
of our Lord One thousand eight hundred and seventy-one, in the thirty-
fifth 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 exccutors, administrators, and
assigns, or such others as I, the said Newton Wilson, my executors,
administrators, and assigns, should at any timo 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," 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 scals, should
particularly describo 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

extended arm; h, the ratchet motion; i, the slotted lever; j, j, the bent
arms with eyes at their extremities; k, stud in needle bar giving motion
to the arrangement.

Figure 4 (edge view) of a portion of the apparatus 'herein-beforc
described under the fourth head of these presents; 7 represents a small
shaft for conveying the stepping motion to the feed bar; m, the driven
pinion, and n, the bevelled or concave disc.
Figure 5 (front) and Figure 6 (edge) views of my new arrangement
for producing the herring-bone and overseaming stitch herein-before
described under the fifth head of these presents. In these Figures, o, o,
is the feed bar; p, the hinged and pendant part of same; q, is the grooved
feed cam; r, the diamond-shaped stud; 8, the screw for regulating the
extent of the traverse. The dotted line in Figure 6 shews where the
cam would have to be cut at the centre of its midfeather, when tho 1
motion is made adjustable by a regulating screw at the extremity of
the feed shaft (4). ·
Figure 7 (side), 8 (front), and 9 (back) views of the clutch arrangement
which in some forms of sewing machines would be useful as a means of
dispensing with the hinged portion of the feed bar, causing the feed to
move bodily on its bearings, and preventing all risk of the diamond-
shaped stud getting out of the intersecting grooves of the feed cam.

In these Figures, A. denotes the feed bar; B, the clutches (of which
there are two); C, C, the double washer in which these clutches operate;
D, the grooved feed cam; E, the regulating screw; F, spring; G, stitch
lever; H, cylindrical hole on feed bar; I, piston working in same;
J, diamond-shaped stud connected with the same and working in the
grooves of the feed cam. In this arrangement a cylindrical hole
bored in the body of the feed bar, immediately behind and parallel with
the grooved feed cam. The regulating screw E is attached to the end of a
the piston which works in this cylinder, and at the side of this piston
is connected the diamond-shaped pin before described. The screw E
regulates the extent of the traverse, whilst the spring holds the entire
feed bar constantly to its work.
Having now particularly described and ascertained the nature of the 3
said Invention, and in what manner the same is to be performed or put

page_text: in practice, I hereby declare that I claim, the Invention as described in
this Specification and illustrated by the Drawings accompanying the
same.
In witness whereof, I, the said Newton Wilson, have hereunto set
my hand and seal, this Third day of April, in the year of our
Lord One thousand eight hundred and seventy-two.
