Pattern or Warp and Shuttle Box Controlling
Mechanism of Fancy or like Looms.
A communication by ALBERT SNOECK, of 11, Footguard Place, Hartford, in the
State of Connecticut, one of the United States of America, Engineer.
I ALFRED GEORGE BROOKES of 55 and 56 Chancery Lane, in the County of
London, Chartered Patent Agent do hereby declare the nature of this invention to
be as follows:-
This invention has for its object to improve and simplify fancy looms, or that
class of looms wherein the harness frames controlling the warps and the shuttle-
box mechanism containing shifting shuttle boxes are controlled as to their order of
movement by or through the distribution of notched jacks, the distribution being
effected by or through a pattern surface or surfaces.
In this class of loom the pattern surface employed consists usually of a chain
having metallic pins or protuberances which act directly against the jacks to
distribute them in order that they may be engaged by a suitable elevator or
depressor to effect the movement of the harness frame or of the shuttle box.
These pattern chains having pins and protuberances are sometimes of very great
length, that depending upon the length of the pattern or figure to be woven, and
such chains besides being of great length and therefore unwieldly and difficult to
handle, are also very expensive to make, and great expense is involved in changing
from one pattern to another, the money invested in pattern chains and the space
required for their storage amounting to a very considerable sum.
To avoid the use of these heavy and expensive pattern chains my correspondent
has devised instead a pattern surface which is made as an endless belt of flexible
material, and in order to enable a thin flexible belt to be used as a pattern surface
I have devised means intermediate said belt and said jacks whereby the strain upon
the belt is reduced to the minimum.
According to the invention there is employed an endless pattern belt composed
of textile material stiffened or solidified without destroying its flexibility, said belt
being provided with suitable holes for the entrance of needles and also, with
suitable holes to engage a pattern barrel in order that the belt may be rotated by
the barrel.
An endless pattern belt composed of cloth and paper united is used, said belt
being provided with suitable holes for the entrance of needles and other holes for
the entrance of pins by which to move the belt.
Also an endless flexible pattern surface may have a series of holes for the
reception of needles, and a series of holes elongated in the direction of the width
of the pattern belt whereby any variations in the width of the belt due to
hygrometric changes will enable the elongated holes in the belt to properly
embrace the pins of the pattern surface, and enable the belt to rest flat or without
bunches.
The endless flexible pattern belt may have a series of holes for the reception of
needles, and having a series of holes for the reception of pins or projections from
a pattern cylinder, said holes being provided with metallic eyelets to strengthen
the same.
In the use with a loom having notched jacks, as described, and an endless belt
like pattern surface, of a series of selectors, a series of needles cooperating with
said belt may be employed to determine the positions of the selectors, and selector
actuating mechanism to act upon such of the selectors as may be determined by

page_text: the holes in the pattern surface, said selectors moved by the selector actuating
mechanism effecting the distribution of the jacks, such plan reducing the strain or
pressure of the needles upon the endless belt-like pattern surface to the minimum.
In a fancy loom having notched jacks there may be employed a flexible endless
belt-like pattern surface a series of needles against which said pattern surface acts,
a series of selectors put into position beside said needles and intermediate said
needles and said toothed jacks, and selector actuating mechanism adapted to engage
such of the selectors as may be determined by the holes in the pattern belt, and an
extractor cooperating with said needles to remove all of them from the holes in the
pattern belt before the rotation of the latter.
The particular shape of the selectors may be varied and the selectors may act
directly against the toothed jacks or through the intervention of fingers.

Improvements in "Pattern
"
or Warp and Shuttle Box Controlling
Mechanism of Fancy or like Looms.
A communication by ALBERT SNOECK, of 11, Footguard Place, Hartford, in the
State of Connecticut, one of the United States of America, Engineer.
I Alfred GeoRGE BROOKES of 55 and 56 Chancery Lane in the County of
London, Chartered Patent Agent 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 for its object to improve and simplify fancy looms, or that
class of looms wherein the harness frames controlling the warps and the shuttle-box
mechanism containing shifting shuttle boxes are controlled as to their order of
movement by or through the distribution of notched jacks, the distribution being
effected by or through a pattern surface or surfaces.
In this class of loom the pattern surface employed consists usually of a chain
having metallic pins or protuberances which act directly against the jacks to
distribute them in order that they may be engaged by a suitable elevator or
depressor to effect the movement of the harness frame or of the shuttle box.
These pattern chains having pins and protuberances are sometimes of very great
length, that depending upon the length of the pattern or figure to be woven, and
such chains besides being of great length and therefore unwieldy and difficult to
handle, are also very expensive to make, and great expense is involved in changing
from one pattern to another, the money invested in pattern chains and the space
required for their storage amounting to a very considerable sum.
To avoid the use of these heavy and expensive pattern chains my correspondent
has devised instead a pattern surface which is made as an endless belt of flexible
material, and in order to enable a thin flexible belt to be used as a pattern surface
he has devised means intermediate said belt and said jacks whereby the strain upon
the belt is reduced to the mininium.
According to the invention there is employed an endless pattern belt composed
of textile material stiffened or solidified without destroying its flexibility, said
belt being provided with suitable holes for the entrance of needles and also with
suitable holes to engage a pattern barrel in order that the belt may be rotated by
the barrel.
An endless pattern belt composed of cloth and paper united is used, said belt
being provided with suitable holes for the entrance of needles and other holes for
the entrance of pins by which to move the belt.

page_text: Also an endless flexible pattern surface may have a series of holes for the
reception of needles, and a series of holes elongated in the direction of the width
of the pattern belt whereby any variations in the width of the belt due to

The endless flexible pattern belt may have a series of holes for the reception
of needles, and having a series of holes for the reception of pins or projections
from a pattern cylinder, said holes being provided with metallic eyelets to strengthen
the same.
In the use with a loom having notched jacks, as described, and an endless
belt-like pattern surface, of a series of selectors, a series of needles cooperating
with said belt may be employed to determine the positions of the selectors, and
selector actuating mechanism to act upon such of the selectors as may be determined
by the holes in the pattern surface, said selectors moved by the selector actuating
mechanism effecting the distribution of the jacks such plan reducing the strain
or pressure of the needles upon the endless belt-like pattern surface to the
minimum.
In a fancy loom having notched jacks there may be employed a flexible endless
belt-like pattern surface, a series of needles against which said pattern surface acts,
a series of selectors put into position beside said needles and intermediate said
needles and said toothed jacks, and selector actuating mechanism adapted to
engage such of the selectors as may be determined by the holes in the pattern belt,
and an extractor co-operating with said needles to remove all of them from the holes
in the pattern belt before the rotation of the latter.
The particular shape of the selectors may be varied, and the selectors may act
directly against the toothed jacks or through the intervention of fingers.

the improvements added to enable the invention to be understood.

Fig. 3 yet another modification.

and,

I have chosen to illustrate the improvements in connection with a fancy loom of
the so called Crompton class.
A represents part of a loom side, having an extension A', said frame supporting
a crank or lay shaft A'.
B represents a harness lever of usual construction it being in practice notched at
each end to be joined in usual manner by cords or connections to the upper and
lower bars of a harness frame.
The lever is notched to rest on a fulcrum A20, and has an extension B' on which
is joined a hooked jack B³, the hooks of which in practice will be engaged by a
suitable elevator or depressor, one located above and the other below the said jacks,
all as provided for in the loom referred to or as illustrated in the Specification of
Letters Patent No. 2195 dated 29th May 1880 granted to William Morgan-
Brown.
"
In the loom referred to and in usual fancy looms using notched jacks of whatever
form, connected with harness levers, connected directly by cording to the upper
and lower bars of harness frames carrying heddles through which warp threads are
led, it has been customary to distribute the notched jacks that they might be
engaged by the elevator used or by the depressor used, according to whether a
particular harness frame was to be raised or lowered; by the action against the
jacks of the rolls or projections of a metallic pattern chain, often very long, heavy,
and expensive, which it is the object of this invention to do away with entirely, and
instead of it use a light-weight but strong belt-like pattern surface E³, composed
preferably of paper and cloth N, the pattern surface surrounding a circular barrel h

page_text: on a shaft mounted in suitable bearings of the loom frame and rotated step by
step in any usual or suitable manner. Fig. 5 shows part of the pattern surface, it
having suitable holes at 3 to receive a series of pins 2, and a series of holes 6 to
receive pins 5 carried by the barrel, the holes 6 being elongated somewhat in the
direction of the width of the pattern surface to thus provide for expansion and
contraction of the said surface in use due to moist and dry atmosphere. These
holes may and preferably will be lined with eyelets.
The pattern surface will be provided at intervals with other holes a, a, according
to the pattern or design to be woven, and the cylinder h will be provided with
numerous holes in regular order, so that, a needle a¹ which is to be used to
designate the lifting of a jack to be engaged by a lifter may pass through a hole in
the pattern surface and enter a hole in the said cylinder but if a jack is to be left
down to be engaged by a depressor, then a portion of the pattern surface will act
directly against the needle, and to enable a belt-like paper surface to stand up to
its work, and last for a good length of time, the strain required to move the needle
must be as little as possible.
I choose to keep the belt-like pattern surface down on the barrel by a rolling
weight or cylinder D', and to prevent the paper surface wrinkling or bunching on
the barrel, I employ a small roll m, mounted in arms m¹ one for each end of the
roll, the roll having an annular groove m', in line with the pins 2, see Fig. 4 a
spring m keeping the roll against the pattern surface.
I provide the loom frame with guides and 9, shown as bars with a series of
holes for the needles, and with a guide bar g² for a series of selectors a², which,
when in one position, determined by the pattern surface, which co-operates directly
with the ends of the needles, may be struck by a selector-actuating device b, shown
as a vibrating bar carried by like arms 6' secured to a rock shaft mounted in the
extension A, and having an arm & provided with a roller or other stud 60, adapted
to be struck and actuated once for each beat of the usual lay of the loom, by a
cam D on a shaft A at the loom side, said shaft having a gear D" engaged by a
gear D on the crank shaft.
When the needle is lifted by the action against it of the paper surface, it has
only to lift a selector, as shown in Fig. 1, by the second selector, and the needle
having the selector which is to be struck enters a hole in the pattern surface and
barrel.
The selector which is left opposite the selector-actuator is struck by the latter
and effects the lifting of a notched jack, the pattern surface in no way resisting the
strain required to lift the jack.
In Fig. 1, the selectors act against fingers g, shown as levers having anti-friction
rolls on which the jacks rest and move to avoid friction.
Before a change of pattern surface for a change of shed I withdraw each needle
entirely above and out of contact with the pattern surface, so as to avoid all wear
or friction, and, to do this I employ an extractor, shown as a bar n extended under
the selectors and mounted at each end in a suitable arm n', attached to a rock
shaft n³, having an arm n³, provided, as shown, with an adjusting device P, which
is struck by an arm 6* as it retires from the selectors, the lifting of the extractor n
acting on all the selectors and pulling the needles above and away from the pattern
surface.
In the modification Fig. 2, the selectors are put in nearly vertical position and
the selector-actuating device is turned sufficiently on the shatt to put it in proper
position to meet the selectors which are moved laterally into or out of range of
movement of its selector-actuator by the needles, which are more inclined than in
Fig. 1, and the selectors act on fingers g, somewhat differently shaped but having
rolls as described for Fig. 1.
In Fig. 2, I have omitted the pattern surface to avoid confusion of the drawings.
The selectors arranged, as in Fig. 2, might be made longer, as in Fig. 3, so that
their heads would contact directly with the notched jacks, to lift them.
In the form in which I have herein shown the invention, the wire from which the

page_text: needles are made is bent to form an eye to receive the selectors and form guides for
them in their sliding movements, but any other suitable guides would answer the
purpose, as the chief function of the needles is to lift and hold up a selector.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. The use in a loom having notched jacks, united to harness levers, adapted to
be connected to harness frames at bottom and top, and to be moved by an elevator
and a depressor, of an endless belt-like pattern surface extended about and moved
by a barrel, a series of selectors, a series of needles co-operating with said pattern
surface to determine the position of the said selectors, and selector-actuating
mechanism to act upon such of the selectors as may be determined by the pattern
surface, the selectors struck and moved directly by the selector-actuating device
effecting the distribution of the notched jacks preparatory to the formation of the
next shed to be made, substantially as described.
2. The use in a fancy loom having notched jacks, of a flexible endless, belt-like.
pattern surface, a series of needles against which said pattern surface acts, a series
of selectors put inte position by said needles and intermediate said needles and.
said toothed jacks, and selector-actuating mechanism adapted to engage such of the
selectors as may be determined by the holes in the pattern belt, and an extractor
co-operating with said needles to remove all of them from the holes in the pattern
belt before the rotation of the latter, substantially as described.
3. The use in a fancy loom having notched jacks, of a flexible endless belt-like
pattern surface, a series of needles against which said pattern surface acts, a series
of selectors put into position by said needles and intermediate said needles and said
toothed jacks, a series of roller carrying fingers, and selector-actuating mechanism
adapted to engage such of the selectors as may be determined by the holes in the
pattern belt, and an extractor co-operating with said needles to remove all of them
from the holes in the pattern belt before the rotation of the latter, substantially a
described.
