IMPROVEMENTS IN THE METHOD OF CONTROLLING THE OPERATION Of THE SHUTTLE BOXES OF LOOMS
Year: 1885

page_text: We, RICHARD LONGDEN HATTERSLEY of Keighley, Yorkshire, Machine Maker,
and JAMES HILL of the same place, Mechanic, do hereby declare the nature of our
invention for IMPROVEMENTS IN THE METHOD OF CONTROLLING THE OPERATION Of
THE SHUTTLE BOXES OF LOOMS to be as follows:-
This invention consists of the application of mechanical means by which the
number of pattern cards used to indicate upon revolving or circular and rising or
any other kind of moveable shuttle boxes of loo.ns, is reduced to a minimum, thus
saving time and expense when long patterns are required.
To accomplish this we make use of the well known automatically reversing
pattern card cylinder and its usual arrangement of parts, or in other words, that
indicating card motion which causes any design in the weft portion of the fabric
being woven, to be inversely repeated as many times as required, and which we
will hereinafter call the primary card motion, the said number of repetitions being
limited by the appropriation of a supplementary pattern card cylinder deriving its
intermittent rotary motion from the primary card motion, through the medium of
suitable levers and other parts in such a manner, that at each reversion of the said
primary card cylinder the said supplementary cylinder is revolved the space of one
card; the pattern surface of which reciprocates the controlment of the primary
cylinder motion so that when the said primary cylinder has accomplished the
required number of reversions, say for example 10, then the interference, by the
use of appropriate levers, connecting rods &°; of the pattern surface on the
10th card of the said supplementary card motion, prevents any further repetition
and so the primary cylinder moves on from one of its series of pattern cards to
another, in this manner obviating the use of the long chain of pattern cards or
the interference by hand (as when the primary card cylinder is manually changed
from one of its series of reversible pattern cards to another) required to produce
the several series of inversely repeated patterns when using only one common, or
the beforementioned primary card cylinder.

page_text: We, RICHARD LONGDEN HATTERSLEY of Keighley Yorkshire, Machine Maker,
and JAMES HILL of the same place, overlooker, do hereby declare the nature of
our invention for IMPROVEMENTS IN THE METHOD OF CONTROLLING THE OPERATION
OF THE SHUTTLE BOXES OF LOOMS and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:
This invention consists of the application of mechanical means by which the
number of pattern cards used to indicate upon revolving or circular and rising or
any other kind of moveable shuttle boxes of looms, is reduced to a minimum, thus
saving time and expense when long patterns are required.
To accomplish this we make use of the well known automatically reversing
pattern card cylinder and its usual arrangement of parts, or in other words, that
indicating card motion which causes any design in the weft portion of the fabric
being woven, to be inversely repeated as many times as required, and which we
will hereinafter call the primary card motion, the said number of repetitions
being limited by the appropriation of a supplementary pattern card cylinder
deriving its intermittent rotary motion from the primary card motion, through
the medium of suitable levers and other parts, in such a manner; that at each
reversion of the said primary card cylinder the said supplementary cylinder is
revolved the space of one card; the pattern surface of which reciprocates the con-
trolment of the primary cylinder motion so that when the said primary cylinder
has accomplished the required number of reversions, say for example 10; then the
interference, by the use of appropriate levers, connecting rods etc; of the pattern
surface on the 10th card of the said supplementary card motion, prevents any
further repetition and so the primary cylinder moves on from one of its series of
pattern cards to another, in this manner obviating the use of the long chain of
pattern cards or the interference by hand (as when the primary card cylinder is
manually changed from one of its series of reversible pattern cards to another)
required to produce the several series of inversely repeated patterns, when using
only one common, or the before mentioned primary card cylinder.
In order to more fully explain our said invention so that the same may be
more clearly understood, we will proceed to describe it by reference to the accom-
panying sheet of drawings wherein Fig. 1 is side elevation and Fig. 2 plan; the
framework in each being omitted so as to form a clearer illustration.
A is the primary card cylinder, having the well known rising and falling
movement, the pattern surface of which, when a reversion in its movement is
required causes the lever a, which is fulcrumed at a', to rise and by the catch b
to partially revolve the catch wheel c which by the tappit & disengages the
catch e and engages the catch e¹, thus accomplishing the desired object, viz., the
reversion of the pattern surface, which may be repeated in either direction as often
as desired.

page_text: To the lever a is attached a connecting rod f which by the lever g and the
catch h, imparts an intermittent rotary motion to the supplementary card cylinder B,
which revolves on the fixed centre ¹, by the ratchet wheel i (which is attached to
it) at each rise of the said lever a. The distance revolved, by the said cylinder B,
at each of its movements being the space of one card.
When the desired number of reversions of the cylinder A have been accomplished,
a pink, on the pattern surface of the cylinder B, is arranged on the series of
cards so as to present itself under the lever 1, lifting it, as shewn by dotted lines
in the drawing; and by the rod m and the lever n, the rod o is drawn so that its
slotted end o¹ shall be in a position to hold the catch b, by the pin p, from contact
with the wheel c when the lever a rises, as is also shewn by dotted lines; and thus
prevent a further reversion for the purpose before stated.
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
1. The use and employment of a supplementary pattern card cylinder deriving
its intermittent rotary motion direct from a primary pattern card cylinder as
herein fully described and illustrated.
2. The use and employment of a supplementary pattern card cylinder to
reciprocate the controlment of a primary pattern card cylinder in the manner and
for the purpose substantially as herein described.
