Improvements in Means or Apparatus employed in Weaving with
the Aid of Card or Pattern Surfaces.
We SIR TITUS SALT, BART., SONS & Co. LIMITED, Manufacturers, WILLIAM
JAMES MONK, Engineer, and DAWSON SUTCLIFFE, Assistant Designer, all of
Saltaire, near Shipley, in the County of York, do hereby declare the nature of this
invention to be as follows :--
This invention has reference to improvements in means, or apparatus employed
in weaving checks, cross overs, or similar fabrics, in looms with the aid of Jacquard
cards, or pattern surfaces, and is designed by simplifying the motion to reduce the
number of cards, or pattern surfaces, employed and economise in production.
The card, or pattern motion with greatly reduced number of box cards is
attained, according to one form of the apparatus, by employing two catches,
engaging teeth, or projections, on a wheel on the card cylinder, so arranged that,
that may be turned backwards, or forwards, or continuously rotated, as may be
desired in either direction.
The card cylinder may be turned backwards, or forwards, using any given
number of cards, which is a multiple of the number of picks required in the
patterns. This card cylinder gives motion, as inay be required, to another cylinder
by means of intervening mechanism and this we have found it convenient to attain
by means of catches which come into contact with the teeth, or projections, on the
card cylinder wheel, when that cylinder is raised and lowered by a suitable rotatory
eccentric. A centred lever carrying a suitable catch is adapted to engage teeth, or
projections, on the second cylinder, when required, and cause its rotation. Another
lever is arranged, so that the teeth, or projections, on the second cylinder cards
come into contact with said lever and moving that lever draw another catch out of
contact with the card cylinder and allow the operating catch referred to, to turn
that cylinder, when no projection is on the cards which are on the second cylinder
the last mentioned lever moves in the opposite direction which throws the catch on
the first mentioned lever out of position and allows the catch moved by the second
lever to come in contact with the card cylinder and turn it in the opposite direction
to which it was previously turned. This backward and forward movement may be
repeated, or alternated, in desired order, as often as required, with the arrangement
of cards on the second cylinder.
The card cylinder may be worked on a fixed stud and the catches may be
operated from the said eccentric, instead of as before described.
By thus governing the operation of the card cylinder by means of a second, or
indicating cylinder, we are enabled to effect the selections for production of pattern
in the weaving with a greatly reduced number of cards employed, as for instance
supposing for a given production the number of cards that would be used with the
ordinary box motion be 700 we design with our improved motion to attain the same
object with (say) from 40 to 50 cards only.

Improvements in Means or Apparatus employed in Weaving with
the Aid of Card or Pattern Surfaces.
We, SIR TITUS SALT BART. SONS & Co. LIMITED Manufacturers, WILLIAM
JAMES MONK, Engineer, and DAWSON SUTCLIFFE, Assistant Designer, all of
Saltaire, near Shipley, in the County of York, 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 has reference to improvements in means, or apparatus employed
in weaving checks, cross-overs, or similar fabrics, in looms with the aid of Jacquard
cards, or pattern surfaces, and is designed by simplifying the motion to reduce the
number of cards, or pattern surfaces employed, and economise in production.
The card, or pattern motion with greatly, reduced number of box cards is
attained, according to one form of the apparatus, by employing two catches,
engaging teeth, or projections, on a wheel on the card cylinder, so arranged that,
that may be turned backwards, or forwards, or continuously rotated, as may be
desired in either direction.
The card cylinder may be turned backwards or forwards, using any given number
of cards of which the number of picks required in the patterns is a multiple. This
card cylinder gives motion, as may be required, to another cylinder by means of
intervening mechanism and this we have found it convenient to attain by means of
catches which come into contact with the teeth, or projections, on the card cylinder
wheel, when that cylinder is raised and lowered by a suitable rotatory eccentric.
A centred lever carrying a suitable catch is adapted to engage teeth, or projections,
on the second cylinder, when required, and cause its rotation. Another lever is
arranged, so that the teeth, or projections on the second cylinder cards come into
contact with said lever and moving that lever draw another catch out of contact
with the card cylinder, and allow the operating catch referred to, to turn that
cylinder; when no projection is on the cards which are on the second cylinder the
last mentioned lever moves in the opposite direction which throws the catch on the
first mentioned lever out of position and allows the catch moved by the second
lever to come in contact with the card cylinder and turn it in the opposite direction
to which it was previously turned. This backward and forward movement may be
repeated, or alternated, in desired order, as often as required, with the arrangement
of cards on the second cylinder.
The card cylinder may be worked on a fixed stud and the catches may be
operated from the said eccentric, instead of as before described.
By thus governing the operation of the card cylinder by means of a second, or
indicating cylinder, we are enabled to effect the selections for production of
pattern in the weaving with a greatly reduced number of cards employed, as for
instance supposing for a given production the number of cards that would be used
with the ordinary box motion be 700 we design with our improved motion to attain
the same object with (say) from 35 to 50 cards only.
DESCRIPTION OF THE DRAWINGS.
Fig. 1, shows an arrangement of card saving motion according to the invention
with card cylinder A arranged to move and acting in a downward direction on the
catches C and D.
For weaving any kind of pattern with a very few box cards: This motion is
worked with two catches instead of one; operating on the card cylinder A. On
the said cylinder are fixed two catch wheels with teeth projecting right and left
so that the cylinder A may be turned backward and forward or continuously as
required in either direction.
The cylinder A may be turned backward or forward on any given number of

page_text: cards of which the number of picks required in the patterns is a multiple. The
card cylinder A gives motion when required to the cylinder B through the lever G
and connecting catch or rod H.
The eccentric I gives an upward and downward motion to the card cylinder A
by means of the slide K in the usual way, so that either of the catches C and D
coming in contact with the catch wheels on cylinder A at the downward stroke
causes the cylinder to be turned in either direction as required. The method of
turning the cylinder A backward and forward is by using a second or indicating
cylinder B which is worked from cylinder A by the lever G and connecting catch
or rod H. On the indicating cylinder B cards with projections are placed, which
projections coming in contact with the tail end of lever F, give motion to the
connecting rod E. On connecting rod E are fixed two studs 1 and 2 projecting
outwardly and so arranged that they come in contact with the tail ends on the
catches C and D which studs move the catch C out of position and allow the
catch D to come in contact with one of the catch wheels on cylinder A and turns
it to the left, when no projection is on the cards which are on the indicating
cylinder B. The lever F is moved in the opposite direction by the spiral spring
which is secured to the end of rod E, and moves catch D out of position and allows
catch C to come in contact with catch wheel on cylinder A and turns it to the
right.
The backward and forward motion of the cylinder A can be repeated as often
as required with the arrangement of cards on the indicating cylinder B.
Figs. 2 and 3 show a modification forming an alternative arrangement of card
saving motion when card cylinder A revolves on a fixed stud and catches C and D
are movable acting in an upward direction.
The card cylinder A, Figs. 2 and 3, works on a fixed stud; on the said cylinder
is secured a peg wheel L so that either of the catches C and D coming in contact
with the peg wheel L turns the card cylinder A, backward and forward or
continuously as required in either direction. The card cylinder A gives motion
when required to the indicating cylinder B by the lever G and catch or pusher H,
the eccentric I gives an upward and downward motion to the slide K, on which are
fixed the catches C and D, so that either of the catches C and D coming in contact
with the peg wheel L on card cylinder A at the upward motion causes the
cylinder A to be turned in either direction as required.
The method of turning the cylinder A backward and forward is by using a
second or indicating cylinder B, which is worked from card cylinder A by the
Llever G, and the catch or pusher H coming in contact with the catch wheel
on the indicating cylinder B: on the indicating cylinder B cards are placed with
projections, which projections coming in contact with the tail end of lever F, gives
motion to connecting rod E; on the connecting rod E are fixed two studs Nos. 1
and 2 projecting outwardly, and so arranged that they come in contact with the
catches C and D, which move the catch C out of position and allow the catch D
to come in contact with the peg wheel L on the cylinder A and turn it to the
left, when no projections are on the indicating cylinder cards B, the connecting
rod E and the lever F are moved in the opposite direction by the spring S, which
is secured to the connecting rod E, and moves catch D out of position and allows
the catch C to come in contact with the peg wheel L on card cylinder A and turns
it to the right.
A pattern taking (say) 700 cards with ordinary box motion may be worked with
this motion with from say 35 to 50 cards.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
In means or apparatus employed in weaving with the aid of card or pattern
surfaces:
1. The herein described method of and apparatus for operating the card

page_text: cylinders by means of a secondary or indicating cylinder the two cylinders being
caused to cooperate by intervening mechanism, substantially as set forth.
2. The arrangement or combination and use of the parts of Jacquard mechanism
for producing the pattern substantially as set forth.
