page_text: LETTERS PATENT to Joseph Alexandro Guivet, of the Firm Guivet
et C., of Troyes (France), Manufacturers, for the Invention of
"AN IMPROVED KNITTING MACHINE TO PRODUCE THE ENDS OR POINTS OF
STOCKINGS' AND Socks' FEET”
Sealed the 28th September 1875, and dated the 3rd April 1875.
PROVISIONAL SPECIFICATION left by the said Joseph Alexandre
Guivet at the Office of the Commissioners of Patents, with his
Petition, on the 3rd April 1875.
I, JOSEPH ALEXANDRE GUIVET, of the Firm Guivet et C., of
Troyes (France), Manufacturers, do hereby declare the nature of the
said Invention for "AN IMPROVED KNITTING MACHINE TO PRODUCE THE ENDS
OR POINTS OF STOCKINGS' AND SOCKS' FEET," to be as follows:-
The principal features in my Invention are,-
1st. Three non-articulated sets of needles or points placed to the right
hand side, and three other sets of points placed to the left-hand side of
the machine, thus forming six sets of needles or points mounted upon
the sliding bar of the well-known Paget or Dutch machine,

page_text: 2ndly. A fixed support placed at the centre of the sliding bar and
serving to lift the needles of the two nearest points.
And, 3rdly. A system of command for these points adapted upon each
guide of the machine.
The Function of the Points.-When the work begins the two outer
points are separated from the two middle ones by an interval equal to
the distance which they have to traverse in order to produce the ordinary
diminutions in the width which may be deemed necessary, and as soon
as the outer points approach the middle ones the interior diminutions of
the
cap fallers begin.
The System of Command for the Points.-This system is symmetrically
adapted upon the two sliders of the machine, and it will be sufficient to
describe one since the other is similar. Upon the main guide of the
machine there is formed a horizontal groove in which slides a bar having
at one end upon its upper surface a little rack, causing the bar to slidē :
by means of a jointed pawl, receiving its own movement from a pawl
lever belonging to the guide of the machine. At the other end of the
slide bar is a hinge head arranged so as to permit the passage without
movement being imparted to it of the command of the middle point,
when the latter proceeds towards the fabric upon the frame (fonture) of
the machine. This head in its return imparts to the same point by means
of a similar head a recoil movement from a needle.
Beneath the main guide of the machine is adapted a series of rocking
blades, these blades are mounted upon a pin and held at their upper
part by a plate keyed upon the slide bar. These blades servo to com-
mand the outer points and uncover them one by one at each movement
of recoil of the slide bar.
Upon the same guide of the machine is also adapted a square or right
angular piece terminated by a head which serves to impel the inner
point upon the support to form the cap of the fallers. This motion is
imparted to the inner points by means of a flat rod enclosed in a groove
passing under the two other points.

filed by the said Joseph Alexandre Guivot in the Great Seal Patent
Office on the 2nd October 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOSEPH
ALEXANDRE GUIVET, of the Firm Guivet et C., of Troyes (France),
Manufacturers, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Third day of April, in the year of our
Lord One thousand eight hundred and seventy-fivo, in the thirty-
eighth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Joseph Alexandre Guivet, Her
special licence, that I, the said Joseph Alexandre Guivet, my executors,
administrators, and assigns, or such others as I, the said Joseph
Alexandre Guivet, 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 law-
fully 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 "AN IMPROVED SEWING MACHINE TO PRODUCE THE ENDS
OR POINTS OF STOCKINGS' AND SOCKS' FEET," upon the condition (amongst
others) that I, the said Joseph Alexandre Guivet, my executors or
administrators, by an instrument in writing under my, or their, or
one of their hands and scals, 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 Scal Patent
Office within six calendar months next and immediately after the date
of the said Letters Patent.
NOW KNOW YE, that I, the said Joseph Alexandre Guivet, do
hereby declare the nature of my said Invention, and in what manner
the same is to be performed, to be particularly described and ascer-
tained in and by the following statement thereof, reference being had
to the Drawings hereunto annexed, that is to say :-
The principal features in my Invention are,—
1st Three non-articulated sets of needles or points placed to the right
hand side, and three other sets of points placed to the left-hand side of
the machine, thus forming six sets of needles or points mounted upon
the sliding bar of the Paget or Dutch machine.

page_text: 2ndly. A fixed support placed at the centre of the sliding bar and
serving to lift the needles of the two nearest points.
And, 3rdly. A system of command for these points adapted symetri-
cally upon each slide of the machine
My Invention will be well understood from the accompanying
Drawings.
Figure 1 is an elevation of the whole machine, Figure 2 is a plan
thereof; and Figures 3 and 4, are transverse sections through the lines
X, X, and Y, Y.
The Function of the Points.-The ends of the feet of the stockings
and socks are produced by the movement, or rather by the displacement
to the right and left, of the points A, A, B, B, C, C, upon the sliding
bar D. In commencing the work the two outer points A, A, aro
separated from the two middle ones by an interval equal only to the
distance which they have to traverse in order to produce the ordinary
diminutions in the width which may be deemed necessary, and as soon
as the outer points A, A, approach the points B, B, the interior diminu-
tions of the foot fallers begin.
The System of Command for the Points. To obtain this movement
of the points my system of command is arranged in the same manner
upon both the slides E, E, of the machine Upon cach slide E is
arranged a horizontal groove, in which slides a bar F held in the groove
by screwed cross pieces a and b The bar has at one end upon its
upper surface a little rack G causing the bar to slide by means of a
jointed pawl II receiving its own movement from a paul lever I, also
jointed and mounted high upon and at the outer end of the slide E, to
which it belongs. The pawl H is carried by a little piece c bolted upon
the slide E, and is also provided with a little gudgeon engaged in a
groove formed in the paul lever I. At the other end of the new slide
picce F is a linge head J arranged so as to permit the passage without
movement being imparted to it of the command of the middle point B,
when the latter proceeds towards the fabric upon the frame (fonture) of
the machine. This head in its return imparts to the same point by
means of a similar head a recoil movement from a needle.
Beneath the slide E is adapted a series of rocking blades K; these
blades are mounted upon a pin and held at their upper part by a plate L

page_text: koyed upon the slide bar F. These blades K serve to command the
outer point A and uncover themselves one by one at cach movement of
recoil of the piece F.
The slide F also carries a square or right angular picco M terminated
by a head O, which serves to impel the inner point Cupon the support N
arranged at the middle of the sliding bar D. In this movement the
support N raises the needles of the point C, and this effects tho
formation of the cap of the faller points. This motion is imparted to
the point O by means of a flat rod P enclosed in a groove formed in the
upper face of the bar D carrying the points.
And having now described the nature of my said Invention in sewing
machines for the purpose set forth and in what manner the same is to
be performed, I declare that I claim,-
Firstly. The employment of non-articulated points arranged sym-
metrically upon the sliding bar at the right and at the left of tho
vertical axis of a sewing machine, as and for the purposes hercin-before
described and as shown in the accompanying Drawings.
Secondly. The employment of a fixed support placed at the centre of
the sliding bar to lift the needles of the two interior points as herein-
before described and as shown in the accompanying Drawings.
And, Thirdly. The system of command for the points, as herein-before
described and as shown in the accompanying Drawings.
In witness whereof, I, the said Joseph Alexandre Guivet, have
hereunto sot my hand and seal, this Thirtieth day of September,
One thousand eight hundred and seventy-five.
