I JAMES CLEGG of Hartford Works Oldham in the County of Lancaster Foreman
do hereby declare the nature of my invention for IMPROVEMENTS IN LOOMS FOR
WEAVING LOOPED FABRICS GENERALLY CALLED "TERRYS" to be as follows:-
My invention relates to looms which are employed for weaving looped fabrics
generally called "terrys" and consists in automatic apparatus by means of which
I control the well known loose reed apparatus by which the terry is formed so that
such terry apparatus shall be at liberty to act or shall be rendered inoperative at
pleasure, I am thus enabled to readily weave a fabric in which the terry is omitted
at any. desired part, and to any desired extent thus forming a fabric in which
stripes wholly or partially of terry are alternated with stripes in which the terry
is omitted.
To accomplish the object of my invention I employ a pattern chain passing
around a chain barrel rotated by means of bevil star wheels or any suitable gearing
from the tappet shaft of the loom.
I provide the chain above mentioned with links which act upon a bowl carried
by a lever which by means of suitable' rods and levers is jointed to a bolt or bar
which at times is caused to prevent the apparatus by which the terry is formed
from operating I compose the chain before referred to of links of two heights the
lower of which will allow the bowl above mentioned to remain in its lower or
normal position the other or higher link being formed so as to act upon and raise
the bowl before referred to and thereby prevent the formation of the terry.
"
In the above described arrangement the attendant can as in looms as heretofore
constructed cause the apparatus producing the terry to become inoperative at any
time when it may be desirable to do so.

I, JAMES CLEGG of Hartford Works Oldham in the County of Lancaster, Foreman
do hereby declare the nature of my invention for IMPROVEMENTS IN LOOMS FOR
WEAVING LOOPED FABRICS GENERALLY CALLED "TERRYS" and in what manner
the same is to be performed, to be particularly described and ascertained in and by
the following statement :---
My invention relates to looms which are employed for weaving looped fabrics
generally called "terrys" and consists in automatic apparatus by means of which
control the well-known loose-reed apparatus by which the terry is formed so that
such terry apparatus shall be at liberty to act or shall be rendered inoperative at
pleasure. I am thus enabled to readily weave a fabric in which the terry is
omitted at any desired part and to any desired extent, thus forming a fabric in
which stripes wholly or partially of terry are alternated with stripes in which the
terry is omitted.
My invention and the manner in which it may be carried into effect are
illustrated by the drawing hereunto annexed in which drawing Fig. 1 is an end
elevation partly in section and Fig. 2 a side view also partly in section of so much
of an ordinary loose-reed terry-forming apparatus as is requisite to illustrate my
invention and the manner in which the same may be carried into effect. The same
letters of reference are applied to corresponding parts in both of the figures above
referred to and in the remaining figures of the drawing which will be hereinafter
referred to. As some of the parts shown in the drawing hereunto annexed are
similar to those in ordinary use I shall only refer to such parts in so far as may be
necessary for the description of my invention and to show the manner in which
the same may be carried into effect.
a is the lathe or slay of the loom. The lathe or slay a is provided with the
reed b. The reed-case c is mounted upon and secured to the arms of the spider-
shaft d. Fast upon the spider-shaft à is mounted the usual locking-lever e which
carries the bowl f. g is the vertical sliding bar to which are bolted brackets h, h¹
which at times act as inclines and are hereinafter called the inclines h h¹ and act
upon the bowl f. The vertical sliding bar g may by means of the bolt or bar j
be locked or prevented from being lifted. The bolt or bar jis "cranked" so that
the its end may pass through the breast-beam k of the loom. The end j¹ of the
bolt or bar jis supported by means of the bracket 7 secured to the breast-beam k.
The other end of the bolt or bar jis jointed to the lever m which is supported
upon the stud n secured to the end-frame o of the loom. The vertical sliding bar g
and the inclines h h¹ are operated by the ordinary means employed for imparting
motion to them. The said vertical sliding bar g and the inclines h h¹ are moved
in the direction indicated by the arrow A by means of a spring. The positions
into which the vertical sliding bar g, inclines h h¹ locking-lever e and reed b are
moved are respectively indicated by full lines in Fig. 1 and by full lines in Fig. 3
which shows upon an enlarged scale certain of the parts shown in Fig. 1. The

page_text: vertical sliding bar g and inclines h, h¹ are forced downwards against the action of
the spring before mentioned into the positions in which they are indicated by full
lines in Fig. 3 by means of a crank, cam or eccentric mounted upon a shaft which
is driven from the tappet-shaft p of the loom.
When the vertical sliding bar g is raised by the spring before-mentioned to its
highest position the lathe or slay a in moving forward in the direction indicated by
the arrow B brings the bowlf between the inclines h h and fixes the position of
the reed-case c and reed b so that the reed 6 does not drive home the weft.
When the vertical sliding bar g is forced downwards into the position in which
it is indicated by full lines in Fig. 3, by the crank cam or eccentric before referred
to, the reed b is locked in a position which enables it to drive home the weft and
push into loops the warp-threads intended to form the terry loops.
When it is desired to weave a "plain beading" the attendant by means of the
bandle m' at the upper end of the lever m slides the bolt or bar j so that its
end will be brought over the upper end g¹ of the vertical sliding bar g and
retain such vertical sliding bar ġ in the position in which it is indicated by full
lines in Fig. 3.
ف
The parts which I have hitherto described are those ordinarily employed in loose
reed terry-forming apparatus and their construction and operation form no part of
my invention.
My invention consists in automatic apparatus by means of which I control the
ordinary loose reed terry-forming apparatus so that such terry-forming apparatus
shall be caused to act or be rendered inoperative at pleasure.
"
On the tappet shaft p is secured a pinion q which gears into and drives the
toothed wheel r. Secured to the toothed wheel r is the peg plate & which as will
be well understood imparts motion to the "noggin-wheel" or "star-wheel "t which
is mounted fast upon one end of the shaft u which shaft u is carried by suitable
brackets secured to the end-frame o of the loom. Fast upon the shaft u is
mounted the chain-barrel w which chain-barrel w is provided with the same
number of spaces for the links of a pattern-chain as there are spaces t' in the
noggin-wheel" or "star-wheel" t. The chain-barrel w carries and imparts motion
to a pattern-chain x by means of the spaces formed in the chain-barrel wand
the pins of the pattern-chain x. The pattern-chain x is formed of links of two
heights the links being of less height and the links ³ of greater height. The
links x2 x3 act upon a bowl y mounted upon a lever z which is mounted fast upon
a shaft 1. The shaft 1 is carried by and capable of being rotated in brackets 2
secured to the end-frame o of the loom. Fast upon the shaft 1 is a lever 3 which
is connected to the lever m previously referred to by a link 4 jointed upon
studs 5, 6. Fast upon the shaft 1 is mounted an arm 7 from which is suspended
a weight 8. The weight 8 tends to keep the bowl y in contact with the pattern-
chain x. The action of the mechanism operating the pattern-chain is so ordered
or "timed" that the movement of the bolt or bar j to lock and unlock the vertical
sliding bar g takes place while the vertical sliding bar g is kept in its lowest
position by the crank cam or eccentric before referred to. The bolt or bar j can
thus be operated without it being necessary to overcome the friction which would
otherwise be produced between the vertical sliding bar g and the bolt or bar j.
In the above described arrangements the attendant by moving the handle m¹ in
the direction indicated by the arrow C can as in looms as heretofore constructed
cause the apparatus producing the terry to become inoperative at any time when
it may be desired to do so.
In the arrangements hereinbefore described the shaft u chain-barrel w and
pattern chain make one movement for each downward movement of the vertical
sliding bar g. Each movement of the pattern-chain x brings a link of such
pattern-chain beneath the bowl y. When a link ³ of greater height is brought
beneath the bowl y the lever will be turned upward in the direction indicated by
the arrow D and by means of the lever 3 link 4 and lever m move the bolt or
bar so that the end 71 of such bolt or bar j will pass above the upper end of the

page_text: vertical sliding bar g so as to lock such vertical sliding bar g in the position in
which it is indicated by full lines in Fig. 3 thus preventing the terry-forming
apparatus from operating until a link of less height is brought .beneath the
bowl y and allows the weight 8 to turn the arm 7 in a direction opposite to that
indicated by the arrow D and by means of the lever 3 link 4 and lever m remove
the end of the bolt or bar j from above the vertical sliding bar g and allow such
vertical sliding bar g to be raised into the position in which it is indicated by full
lines in Fig. 1 and by dotted lines in Fig. 3 so as to permit the terry-forming
apparatus to again come into operation.
By forming the pattern-chain x of the requisite number of high and low links
arranged in the requisite order I am enabled to weave a fabric in which the terry
is omitted at any desired part and to any desired extent, thus forming a fabric in
which stripes wholly or partially of terry are alternated with stripes in which the
terry is omitted.
In another arrangement of my invention instead of employing a pattern-chain
formed of links of two heights as above described I employ a pattern-chain formed
of plates of metal connected together by means of rings passing through holes in
the said plates some of which plates of metal have an additional hole formed in
each of them while others are without the additional hole.
This arrangement of my invention is illustrated by Figs. 4 and 5 of the drawing
hereunto annexed Fig. 4 being an end elevation and Fig. 5 a side view of such
parts only as are requisite to illustrate this arrangement of my invention.
As many of the parts shown in Figs. 4 and 5 correspond in construction and
operation to those shown in and previously described in reference to Figs. 1 and 2
I shall affix to such parts the same letters of reference as are applied to corresponding
parts in Figs. 1 and 2.
Upon the shaft u is mounted a chain-barrel w. Around the chain-barrel w
passes a pattern-chain 9 which is formed of plates of metal connected together by
rings 10 The chain-barrel w moves the pattern-chain 9. Fust upon the toothed
wheel is a tappet 11. Secured to the end-frame o of the loom is a stud 12 upon
which is mounted a lever 13 one end of which lever 13 is at times acted upon by
the tappet 11. The end 13% of the lever 13 passes beneath a lever 14 mounted fast
upon the shaft 1. The lever 14 is provided with a peg or stud 15 which is capable
of at times entering into holes 16 which are formed in some of the plates of the
pattern-chain 9 Fast upon the shaft 1 is mounted a lever 17 which carries a
stud 18 The stud 18 passes into a slot 19 formed in one end of a link 20 the other
21 is a
end of which link 20 is jointed to the lever m turning upon the stud n
spring connected at one of its ends to the stud 18 fast upon the lever 17. The
other end of the spring 21 is secured to a stud 22 projecting from the lever m
The weight 8 tends to turn the lever 14 in the direction indicated by the arrow E.
The operation of the shaft u is the same as previously described in reference to
Figs. 1 and 2. The rotation of the tappet 11 will by means of the lever 13 raise
the peg or stud 15 clear of the pattern-chain 9. The pattern-chain 9 will then be
free to be moved by the rotation of the chain-barrel w so that a fresh plate may be
brought beneath the peg or stud 15. A further rotation of the tappet 11 will allow
the peg or stud 15 to descend.
If a plate of the pattern-chain 9 having a hole 16 formed therein is brought by
the rotation of the chain-barrel w beneath the peg or stud 15 the peg or stud 15
will pass through the said hole 16 and into a recess formed in the chain-barrel w
and allow the lever 14 to descend. The descent of the lever 14 will cause the
lever 17 to turn in the direction indicated by the arrow F and by means of the
link 20 turn the lever m in the direction indicated by the arrow C and so cause
the end of the bolt or bar j to pass above the upper end of the vertical sliding
bar g and thereby lock the said vertical sliding bar g in the position in which it is
indicated by full lines in Fig. 3 thus preventing the terry-forming apparatus from
operating. Should the next plate brought beneath the peg or stud 15 be one
without the hole 16 which is formed in some of the plates the peg or stud 15 will

page_text: be supported by such plate and no further movement of the lever 14 in the direction
indicated by the arrow E will take place and the end j¹ of the bolt ; will remain
clear of the upper end of the vertical sliding bar 9 thus leaving the vertical
sliding bar g at liberty and permitting the terry-forming apparatus to again come
into operation.
The slot 19 in the link 20 and the spring 21 allow the lever 14 to be raised by
the tappet 11 so that the peg or stud 15 may be clear of the plates of the pattern-
chain 9. The slot 19 in the link 20 and the spring 21 also allow the attendant
to move the lever m by the handle m¹ to render the terry-forming apparatus
inoperative.
By employing a pattern-chain composed of plates and rings I am enabled to
employ a longer pattern-chain than can be employed when the pattern chain is
formed of links such as those described in reference to and shown in and by Figs. 1.
and 2 of the drawing hereunto annexed.
I would have it understood that I do not confine myself to the use of my
invention precisely as herein before described as the manner in which my invention
may be carried into effect may be somewhat varied without departure from the
principles of my invention.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same 'is to be performed I declare that what
I claim is:
For use in looms for weaving looped fabrics generally called "terrys” the
automatic apparatus constructed arranged and operating substantially as herein-
before described in reference to the drawing hereunto annexed, for controlling the
loose reed apparatus by which terry is formed so that such terry apparatus shall be
at liberty to act or shall be rendered inoperative at pleasure.
