Improvements in or connected with Knitting Machines.
We, GUSTAV FRIEDRICH GROSSER, of Markersdorf, near Burgstadt, in the
Kingdom of Saxony and Empire of Germany, Manufacturer, and JAMES FOSTER,
of 41, Friargate, Preston, in the County of Lancaster, Knitting Machine Patentee,
do hereby declare the nature of this invention and in what manner the same is to be
performed to be particularly described and ascertained in and by the following
statement:-
This invention relates to the production of an improved knitted fabric in which
a strand of cotton or other cheap or inferior yarn is introduced or "sandwiched "
between two other strands or threads of wool or superior yarn in such manner
that when knitted into the fabric the two woollen threads are on the front and
back or in circular work on the outside and inside of the fabric respectively the
cotton thread or yarn remaining hidden between them and being practically invisible.
Heretofore the different arrangements of knitting machine apparatus known to us
have only permitted this effect to be produced-but with only partial success-in
rib or Cardigan work. Now the object of this invention is to provide means or
apparatus whereby the successful sandwiching of the inferior yarn may be effected
more particularly in flat work or in circular plain-knit-web or hosiery goods. To
this end we employ a yarn guide of novel construction the said guide having-in
the case of a Lamb or Foster type of machine-three vertically directed holes
standing in line side by side above the needles the cotton or inferior yarn passing
down to the needles through the central hole and the two woollen or superior yarns
passing down alongside through the two adjoining holes one on each side of the
central hole.
In the accompanying drawings,
Fig. 1 illustrates the construction and arrangement of our improved yarn guide
as applied to a knitting machine of the Lamb or Foster or parallel bar type.
a. a. are the needles 6 the triple-eyed yarn guide having the three holes c c and c²
the inferior yarn d passing down through the central hole c' and the woollen or
superior yarns e and passing down through the two side holes c and c. The
improved yarn guide may be affixed to the knitting machine in any convenient
manner.
Fig. 2 is a sectional plan view of the lower part of the improved yarn guide and
Fig. 2 is an underneath view of the same.
Fig. 3 shews the position of the triple-eyed yarn guide as applied to a knitting
frame in which the needles are arranged horizontally.
For producing rib work with sandwiched yarn we preferably employ a circular
knitter of any of the ordinary types the improved yarn guide being so arranged
relatively to the vertical needles thereof as that the three holes of the yarn guide
shall stand or point horizontally towards the working needles and in a vertical line
one above the other. It will be understood that in addition to ribbed fabrics plain
circular or Cardigan work consisting of sandwiched yarn may by the employment
of our improved yarn guide be produced in circular knitters.
Fig. 4 is a diagrammatic view shewing the position occupied by the inferior or
inner yarn d in the improved knitted fabric relatively to the two superior or outer
yarns e and f.
It will be obvious that if the sandwiched cotton or inferior yarn is to be entirely
invisible in the knitted fabric the two woollen or superior yarus (one on each side
thereof) must be sufficiently thick for the purpose.

page_text: Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed we declare that what
we claim is :-
1. Producing knitted fabric in which an inferior or inner yarn and two superior
or outer yarns are knitted into the said fabric so that the two superior yarns will
be respectively on the back and front-or in circular work on the outside and
inside of the fabric leaving the inferior yarn between the two superior yarns in
manner substantially as hereinn bove described and shewn in the drawings.
2. For producing knitted fabric of the kind described in the preceding claim
the use or employment in a knitting machine of a triple-eyed yarn guide constructed
and arranged substantially as described and shewn in the drawings.
