We, JOHN HARRIS COOPER Hosiery Manufacturer and GEORGE BLUNT Machinist
both of St. Margarets Works Leicester do hereby declare the nature of this invention
to be as follows:-
The object of this invention is to produce a deep welt-to form such a welt to a
one and one, two and one or any other rib we employ what is known in the Trade as
a push back but so arranged that it can work between the cylinder of the rib and
frame needles and be regulated to fall with the production of the work either by means
of a spring device or by other means. A great number of courses can in this way be
produced in what is known as the plain part of the welt of a stocking making it more
tubular in appearance than in the welts now ordinarily made.

We, JOHN HARRIS COOPER, Hosiery Manufacturer and GEORGE BLUNT Machinist
both of St. Margarets Works Leicester 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:-
The object of this invention is to produce a deep welt. To form such a welt to a
one and one, two and one or any other rib we employ what is known in the Trade as
a push back but so arranged that it can whilst a welt is being formed work between
D

page_text: the cylinder of the rib and frame needles and be regulated to fall with the production
of the work either by means of a spring device or by other means.
A great number
of courses can in this way be produced in what is known as the plain part of the
welt of a stocking making it more tubular in appearance than in the welts now
ordinarily made.
The drawing annexed shews a push back arranged as above described to work
downwards between the cylinder of the rib and the cylinder of the frame needles. It
is shewn applied to a machine fully described in the Specification of an application for
Patent bearing even date herewith No. 5998 but can be applied to other constructions
of circular rib machines.
Figure 1 is a side clevation of the machine.
Figure 2 is a plan view of the frame needles and machine needles with the push
back descending between them.
In these figures A are the frame needles-B the machine needles-C a thin metallic
blade forming the push back. It is carried by a lever D acted on by a cam surface E
on an axis F to which a revolving step by step motion is imparted whilst a welt is
being formed. The lever D is by a spring D¹ held against the circumference of the
cam E and just as a welt commences to be formed the cam allows the spring D¹ to
turn the lever I and make the push back blade C descend between the two cylinders
and it continues to do so during the time that the machine needles remain out of action
with loops upon them and during the time that 8, 9 or other number of plain courses
are being produced on the frame needles-the push back descending more and more as
the work progresses until the last plain course has been completed. Then when the
machine needles are again to be brought into action the push back is raised so as only
to bear upon the next course of work and after the completion of this course it is again
raised so as to go entirely out of action-the machine then goes on to produce ordinary
ribbed work until the next welt is to be formed.
The way of forming the welt in the machine shewn in the drawing is fully described
in the Specification of the Patent application No. 5998 above mentioned. The push
back might be applied to other circular knitting machines for producing ribbed work
to similarly hold down the work whilst a welt is being formed-and other means
might be adopted for causing it to descend as a welt is being formed.
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 employment of a push back made to descend between the cylinder of the frame
needles and the machine needles of a circular rib machine during the time that a welt
is being formed on such machine substantially as described.
