IMPROVEMENTS IN MACHINERY
Year: 1882

page_text: LETTERS PATENT to John Kiddier and Herbert Kiddier, of the firm of John
Kiddier and Sons, of the town and county of the town of Nottingham,
Hosiery Machine Makers, for an invention of IMPROVEMENTS IN MACHINERY
"
PROVISIONAL SPECIFICATION left by the said John Kiddier & Herbert
Kiddier at the Office of the Commissioners of Patents on the 13th May 1882.
JOHN KIDDIER, and HERBERT KIDDIER of the firm of John Kiddier and Sons,
of the town and county of the town of Nottingham, Hosiery Machine Makers,
IMPROVEMENTS IN MACHINERY AND APPARATUS EMPLOYED IN THE MANUFACTURE
OF LOOPED FABRICS,"
Our improvements relate to that class of knitting machines employed in pro-
ducing articles known as pants, with split hips and twisted ankles, vests and
similar articles in which adjustable stops are employed to regulate the traverse of
the thread carriers. We propose to employ two screws lying parallel to each other,
upon which stops for the thread carriers are traversed to the right or left as
required. Each stop is not only capable of being separately adjusted, but it can
also be engaged, or disengaged as the case may require by the following means,
the outer end of the axle of one screw is provided with two ratchet wheels and
clawkers, either of which is placed in operation, by the attendant, the clawkers
are hinged to a lever rocking on an axle carried by the framing of the machine,
the lever having a rising and falling movement given it by a cam, besides the two
ratchet wheels, each screw may carry a toothed wheel, each of which engages with
the teeth of an intermediate wheel, by which means both screws may be driven
simultaneously, or either or both may be stopped, by throwing the intermediate
wheel out of gear. Or instead of employing toothed gearing to operate the screws
simultaneously, both screws may be operated by means of levers and clawkers.
By such means we are enabled to dispense with a great number of stop bars, or
rods, heretofore used, and which necessitated the employment of a fresh set of
stops to each variety, and size of article manufactured.

ducing articles known as pants with split hips, and twisted ankles, vests, and

the thread carriers. We propose to employ two screws lying parallel to each other

mediate wheel out of gear.
Or instead of employing toothed gearing to operate the screws simultaneously,
both screws may be operated by means of levers and clawkers. By such means we
are enabled to dispense with a great number of stop bars or rods heretofore used,
and which necessitated the employment of a fresh set of stops to each variety and
size of article manufactured

page_text: of the rods I and J when placed in position and the stops G and H are slid clear
of them. There is also a fixed stop W capable of adjustment the use of which we
will describe hereafter. The remainder of the parts shown are of the usual con-
struction. The above described apparatus is applied to each end of the knitting
machine both acting in conjunction. In order that the use of the screws and
stops may be fully understood, we will proceed to explain the process of making
what are known as split hips and twisted ankle pants. We commence with the
top of one side of the pant which consists of two strips of fabric separated at the
place which is to fit the hip, by about two and a half inches, the carrier on the
rod I supplies the left hand division of needles with cotton or other yarn
while the carrier on the rod J supplies the right hand division of needles, the
motion of the carrier rod I being arrested by the fixed stop W, and the carrier
rod J, by the stop M as often as required, the fabric being made under the above
conditions until say half an inch in length is made, from which point, the widening
of the back (that is in this case the extreme right hand selvage) is extended by
the well known filling up instruments at the same time the two centre selvages
and the left hand selvage is continued as before until say six inches in length of
fabric is made at this point it is necessary to widen the two centre selvages until
they meet, at the same time the widening of the right hand selvage is continued as
before for this purpose the intermediate wheel P is caused to engage with the two
wheels O and Q, thus transmitting the same motion to the screw K as that given
to the screw A by the clawker C. The two centre selvages being thus brought
together the carrier rod J is thrown out of action the fabric is made with the
carrier on the rod I, the intermediate wheel P being disconnected at the same
time as the clawker C is thrown out of action. The widening of the right hand
side is further continued and when finished straight selvage is made while the
widening on the left hand side is made which forms the gusset, the stop W is
withdrawn, and the stop G is brought down to take its place and when the
widening of the left side of the fabric is finished the narrowing of the leg proceeds
in the usual way.
To make the twisted ankle the carrier rod J is again brought into action, the
two carriers making the fabric in two parts separated by a space of two needles,
the strips of fabric are made say seven inches long, the narrowest width is trans-
ferred to the other side of the remaining strip of fabric, the carrier rod J is
withdrawn, and the narrowing proceeds in the usual way.
By such means we are enabled to dispense with a great number of stop bars or
rods heretofore used, and which necessitated the employment of a fresh set of stops
to each variety and size of article manufactured.
Having now described the nature of our said invention, and in what manner
the same may be performed, we declare that we claim,
The construction and employment of two screws, at each end of a rotary knitting
machine, operating singly or in combination, and carrying adjustable stops, to
regulate the traverse of thread carriers, substantially as herein before described and
illustrated in the Drawings annexed.
In witness whercof we the said John Kiddier and Herbert Kiddier havo
hereunto set our hands and seals this Twenty eighth day of September
in the year of our Lord One thousand eight hundred and eighty two.
