page_text: We, JOHN HARRIS COOPER of Evington in the County of Leicester and WILLIAM
JAMES FORD of Humberston in the County of Leicester Hosiery Manufacturers do
hereby declare the nature of this invention to be as follows:-
Our Invention relates mainly to machines of the type known as "Lambs
Patent" improvements upon which were described in the Specification of a Patent
applied for by us N° 1450 in the present year. The object of our invention is to
enable an elastic or rigid thread to be inserted between the rib and frame loops of
the fabric when ribbed fabrics are being made on machines of this type.
Above the two rows of needles of the machine we fix a bar along which a slide
carrying a thread eye and a bobbin which holds a rubber or other thread to be
supplied to such thread eye can be slidden to and fro.
In the slide we have a recess for a bolt from the ordinary thread guide to
enter this recess is made wide enough to allow the ordinary guide to have the
lead of the guide carried by the slide in order that the rubber or other thread may
be laid between the loops upon the two sets of needles just after the needles have
been drawn downwards and the work knocked over upon them.
In this way when the needles are again caused to rise and a fresh row of work is
produced upon them the rubber or other thread will be held between the loops of
work produced on the two rows of needles. The rubber or other thread can be
placed in any desired part of the work for instance if a rubber thread be used it
can be placed in the band or collar or wristband of a Jersey or in the band or
bottom of trousers or knickers and by using a pattern chain operated in the
manner described in the specification of a Patent applied for by us No 1450 in the
present year we can control the position and depth of work into which such
rubber or other thread is introduced.
An elastic or other thread can in the same way be laid between the loops upon
the frame and machine needles of ordinary flat or rotary rib frames after the.
knocking over of the work upon the needles but it is far preferable to use a
machine of the Lamb type when a thread is to be laid into the fabric in the above
described manner as in this machine the thread layer for laying in this additional
thread can follow closely after the ordinary thread layer and the work can be
produced on the machine just as quickly as ordinary plain work.

page_text: of the needle plates-B¹ B¹ are projections on one of the driver bars for sliding the
thread layer to and fro.
All these parts are constructed in the ordinary well known manner. The
manner in which the cams are formed to produce ribbed work is also well
understood so that we have not thought it necessary to shew them in the
drawings.
G is a bar mounted horizontally above the top of the needle bars. H is a slide
capable of being slidden to and fro along one side of this bar and carrying a thread
eye H for laying an india rubber thread or it may be a non-elastic thread or cord
between the needles. It is especially to be observed that this thread or cord is
not laid so as to be caught and looped by the needles as is the case in the
improvement to which our former Patent No 145085 applies but between the
needles so that the thread or cord remains unlooped and lies straight in the work.
In order that this may be the case the thread eye H¹ is caused to lay so that it
does not deliver the elastic thread or the cord until after the needles have been
drawn downwards and the work knocked over upon them.
In place of the thread eye H₁ lagging behind that of the ordinary or main
thread layer E it may precede it at such a distance as to lay the elastic thread or
the cord between the needles before they rise to receive the thread from the
ordinary thread guide; the former method is illustrated by the drawings and is
usually more convenient.
The slide H is moved to and fro by a spring catch J carried by an arm K. The
catch is pressed by a spring into a notch in the top of the slide. The arm K
extends from a slide L which can be slidden to and fro along a bar M just in the
same way as the slide H is slidden to and fro along the bar G but the pro-
jections B B which drive the slide L are further apart than the projections B₁ B¹
which give motion to the ordinary thread layer so that when the direction of
movement of the bars B changes the slide L dwells for a longer time than the
ordinary thread layer E.
N is a drum on which the weight or cord is wound and O is a weighted foot
pressing on the flange of the drum to prevent it turning too freely.
In Figure 1 the slide L is not in contact with either of the projections B* and
will dwell whilst the thread layer E passes it.
When the elastic or other thread or cord is not required the catch J can be
turned back so as not to engage with the slide H.
The rubber or other thread can be placed in any desired part of the work for
instance if a rubber thread be used it can be placed in the band or collar or wrist-
band of a Jersey or in the band or bottom of trousers or knickers and by using a
pattern chain operated in the manner described in the specification of our former
patent already referred to we can control the position and depth of work into
which such rubber or other thread is introduced the tappets on the chain operating
as described in the specification of our said former patent to stop the machine
whenever the slide H is to be put into and out of work.
It is obvious that in place of operating the slide H by the second slide L it may
receive motion from the ordinary thread layer or guide E; in this case we arrange
as follows:-
In the slide we have a recess for a bolt from the ordinary thread guide to enter;
this recess is made wide enough to allow the ordinary guide to have the lead of the
guide carried by the slide in order that the rubber or other thread may be laid
between the loops upon the two sets of needles just after the needles have been
drawn downwards and the work knocked over upon them.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is:-
The combination with a knitting machine in which two straight rows of needles
inclined to one another are used and in which the work is led downwards through

page_text: a narrow space between the upper ends of the rows of needles, of an additional
thread layer which can be slidden to and fro along a bar fixed above the upper
ends of the two sets of needles and which operates at a distance from the ordinary
thread layer, laying in its thread or cord not so as to be caught and looped by
the needles but between them when they are down so that the needles rise 5
over the thread or cord which consequently remains unlooped and lies straight in
the work.
