HENRY HARRIS LAKE, of the firm of Haseltine Lake and Co., Patent Agents,
Southampton Buildings, London, " IMPROVEMENTS IN AND RELATING TO MACHINES
FOR THE MANUFACTURE OF LOOPED FABRICS [A communication to him from
abroad by La Société Couturat & Cie of Troyes, France, Manufacturers]
"
This invention relates to machines for the manufacture of looped fabrics such as
stockings, socks, and like articles, and my improvements are applicable to all
machines of this kind, either rectilinear or circular, or whether they are for the
production of ribbed or plain work.
My improvements consist essentially in employing a double set of sinkers to
effect the looping or curving of the thread or yarn in an opposite direction, each
one taking only half the quantity of yarn necessary for making the stitch or mesh,
the sinkers of one set being formed differently to those of the other set, and
these sets operating, one in, or upon, the other under the action of a jack with
two arms or branches.
In carrying the said invention into practice the two sets of sinkers are arranged
to slide in metallic guides, being operated by two-armed jacks which impart to the
said sinkers the motion (in an opposite direction) necessary to place the portion of
yarn required for a stitch or mesh into a looped or curved form. A bar above the
two sets of sinkers is employed to cause the same to descend after the line of yarn
has been put into the looped or curved condition and to cause the said yarn to bo
delivered to the needles. A bar is provided for uniting or holding together the
two sets of sinkers at the proper moment in the formation of the mesh or stitch,

page_text: this bar also operating to replace the said sinkers in the proper position for again
operating in a similar manner upon the next line of yarn. Another bar is provided
which is divided so as to produce divisions or spaces in pairs, this bar having for
its object to disengage the mesh and to protect it from the lower point of one set
of sinkers. This bar comes underneath the two sets of sinkers at the moment
when they are united as the stitch or mesh is being formed, and the aforesaid lower
point enters the proper space or division in the said divided bar. The latter rises
with the two sets of sinkers and comes into connection with one set of the needles,
after which it makes a forward movement to prevent the line of yarn being caught
by the lower points of one set of the sinkers. A presser serves at first to press the
Deedles of. one set, and afterwards the others. A bar which is divided at its upper
end serves as a guide and support to one set of needles, and another bar is provided
for looping or tying and knocking over the two stitches or meshes after the
two movements of the presser upon the needles as aforesaid.

HENRY HARRIS LAKE, of the firm of Haseltine, Lake, and Co, Patent Agents,
Southampton Buildings, London. "IMPROVEMENTS IN AND RELATING TO MACHINES
FOR THE MANUFACTURE OF LOOPED FABRICS."-a communication to me from abroad
by La Société Couturat & Cie., of Troyes, France, Manufacturers.
This invention relates to machines for the manufacture of looped fabrics such as
stockings, socks and the like, and is applicable to all machines of this kind whether
rectilinear or circular, or for the production of ribbed or plain work.
The said invention consists essentially in employing a double set of sinkers to
effect the looping or curving of the thread or yarn in opposite directions, each one
taking only half the quantity of yarn necessary for making the stitch or mesh, the
sinkers of one set being formed differently from those of the other set and these
sets operating one in, or upon, the other under the action of a jack with two arms
or branches
In the accompanying drawing
Figure 1 is a transverse section of part of a machine for making looped fabrics,
provided with improvements according to this invention.
Figures 2 to 5 are views hereinafter referred to.
a and b indicate two sinkers shewn separately in Figures 4 and 5 and arranged to
slide in the metallic guides p, p¹ and g. The said sinkers are operated by the two-
armed jack which imparts to the said sinkers the motion (in opposite directions)
necessary to place the portion of yarn required for a stitch or mesh into a looped
or curved form. The bar e placed above the two sinkers is employed to cause the
same to descend after the line of yarn has been looped or curved, and to cause the
said yarn to be delivered to the needles n, as shewn in Figure 2 which represents
the two sinkers descending upon the needle n the line of yarn being looped. The
bar & serves for uniting or holding together the two sets of sinkers at the proper
moment in the formation of the mesh or stitch, as illustrated in Figure 3 which
shows the positions of the two sets of sinkers when the mesh is being formed.
This bar also operates to replace the said sinkers in their proper positions, shewn
in Figure 1, for again operating in a similar manner upon the next line of yarn.
The bar c is divided so as to produce divisions or spaces in pairs, and has for its
object to disengage the mesh and to protect it from the lower notch of a sinker b.
This bar comes underneath the two sets of sinkers at the moment when they are
united as the stitch or mesh is being formed and the aforesaid lower notch enters
the proper space or division of the said bar c. The latter rises with the two sets
of sinkers and comes into connection with one set of the needles n, after which it
makes a forward movement to prevent the line of yarn being caught in the lower
notch of one set of the sinkers. The presser 7 serves at first to press the needles
of one set n, and afterwards the needles of another set o. A bar k, which is
divided at its upper end, serves as a guide and support to the set of needles n, and
the bar m serves for looping and knocking over the two stitches or meshes after
the two movements of the presser upon the sets of needles n and o.
Having thus fully described the said invention as communicated to me by my
Foreign Correspondents and the manner of performing the same, I wish it understood
that I Claim :-
The application of the above described improvement to all kinds of machines
used for the manufacture of looped fabrics such as hosiery, whether the said

page_text: machines are rectilinear or circular, or whether used for the production of ribbed
or plain work as above described, and which consists in utilizing the second set of
sinkers for looping as well as for the other operations which it usually performs in
all machines for making looped fabrics, substantially as set forth.
In Witness whereof I the said Henry Harris Lake have hereunto set my hand
and seal this Fifteenth day of September in the year of Our Lord one thousand
eight hundred and eighty three.
HENRY H LAKE (L.S.)
