Improvements in Looms for Weaving Terry Fabrics.
We, JOHN WILLIAM HILL, of Springfield Towel Works, Stockport, near
Manchester, Manufacturer, and EDWARD BARDSLEY, of 16, Heathland Terrace,
Shaw Heath, Stockport, near Manchester, Mechanic, do hereby declare the
nature of our said invention to be as follows:--
Our improvements refer to looms for weaving terry fabrics and relate to what
is known as the terry motion in which the reed pocket is allowed to open for
say two picks and to close for the third pick. The means heretofore adopted
for closing the reed pocket have been liable to allow the reed to jar or vibrate,
or to only partially close the said pocket, with bad or imperfect weaving as a
result. The power absorbed in operating the parts has also been very con-
siderable.
According to our invention, which has for its object to hold the reed pocket
tight when requiring to be closed and prevent all vibration of the reed, we
employ a rod or shaft below or near the reed extending, by preference, from
end to end of the reed. Upon such shaft and at suitable distances apart we
arrange a set of fingers or cranks, extending upwards and towards the reed
pocket.
Also upon the said shaft we mount a lever arm adapted directly, or indirectly,
to ride or rest upon the links of an endless chain carried by a small wheel or
runner driven at a suitable speed from the cam or other shaft of the loom.
The chain is made up of two lengths of links of different sizes, and as it
travels over the wheel and beneath the arm aforesaid, the links alternately
raise and lower the said arm With each raising of the arm the aforesaid
cranks are caused to engage with and hold the reed pocket firmly closed against
the reed and with such movement timed to take place at say each third pick
and as the reed is moving forward, the reed is effectually locked or held closed
at the right moment.
.
By varying the length of the chain, or the speed of the wheels over which it
passes, the locking of the reed in relation to the number of picks may vary.
In terry fabrics with alternate plain parts our invention dispenses with the
arrangement commonly used for alternately engaging and disengaging the terry
motion, and thus takes a considerable load off the loom.
Whilst preferring the chain device aforesaid, a disc and eccentrically mounted
bowl or other device for periodically raising the lever arm may be adopted.
For holding the reed open we employ the ordinary arrangement or employ a
further lever arm with bowl or cam adapted to operate against a bracket or
fixture upon the reed or loom frame, or under control of the chain aforesaid.
Dated this 1st day of June 1899.

We, JOHN WILLIAM HILL, of Springfield Towel Works, Stockport, near
Manchester, Manufacturer, and EDWARD BARDSLEY, of 16, Heathland Terrace,
Shaw Heath, Stockport, near Manchester, Mechanic, 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:-
Our improvements refer to looms for weaving terry fabrics and relate to what
is known as the terry motion in which the reed pocket is allowed to open for
say two picks and to close for the third pick. The means heretofore adopted
for closing the reed pocket have been liable to allow the reed to jar or vibrate,
or to only partially close the said pocket at the third pick, with bad or imperfect
weaving as a result. The power absorbed in operating the parts has also been
very considerable.
According to our invention which has for its object to hold the reed pocket
tight when requiring to be closed and prevent all vibration of the reed, we
employ a rod or shaft below or near the reed extending, by preference, from
end to end of the reed. Upon such shaft and at suitable distances apart we
arrange a set of fingers or cranks, extending upwards and towards the reed
pocket. Also upon the said shaft we mount a lever arm adapted directly, or
indirectly, to ride or rest upon the links of an endless chain carried by a small
wheel or runner driven at a suitable speed from the cam or other shaft of the
loomi.
The chain is made up of two lengths of links of different sizes and as it
travels over the wheel and beneath the arm aforesaid, the links alternately
raise and lower the said arm, With each raising of the arm the aforesaid
fingers or cranks engage with and hold the reed pocket firmly closed against
the reed and with such movement timed to take place at say each third pick
and as the reed is moving forward, the reed is effectually locked or held closed
at the right moment.
By varying the length of the chain, or the speed of the wheels over which it
passes, the locking of the reed in relation to the number of picks may vary.
In terry fabrics with alternate plain parts our invention dispenses with the
arrangement commonly used for alternately engaging and disengaging the terry
motion, and thus takes a considerable load off the loom.
Whilst preferring the chain devices aforesaid, a disc and eccentrically mounted
bowl or other device for periodically raising the lever arm may be adopted.
For holding the reed open we employ the ordinary arrangement or employ a
further lever arm with bowl or cam adapted to operate against a bracket or
fixture upon the reed or loom frame or under control of the chain aforesaid.
The accompanying drawing illustrates an arrangement of the parts, Fig. 1
representing the reed locked or shut for say two picks, and Fig. 2 representing
the reed unlocked or open for the third pick.
Fig: 3 represents a similar view to Fig. 1 with the locking and unlocking
devices operated by slightly different means.
(A) is the loom sley, and (B) the reed, mounted in the usual way, and held
in its position by the loose part (C), which is carried at the extremities of a
series of hinge plates (I)) from the rod (E). Fast upon the latter is a lever (F)
and the end of such lever carries a small runner (G). Upon the usual rising
and falling bar (H) are a set of inclines (I) and (J), and such inclines in rela-
tion to the runner (G) are so set that as the reed beats up and approaches the

page_text: bar (H) the runner impinges against one or other of such inclines according to
the elevation of the bar (H) and causes the lever (F) either to tilt up or down
and consequently open or shut the reed pocket. The reed is held normally
closed by a spring (K), and the opening and closing of the reed pocket is deter-
mined by the rise and fall of the bar (A), in the ordinary way, under the impulses
of a lever arm (L) and chain (M), or eccentric (N), driven from any suitable
source, but preferably from the cam shaft.
The chain (M) is composed of two sizes of links and its effect on the arm (L)
is such as to lower the bar (H) every third pick and to keep it raised for two
picks.
Due to the elasticity that exists between the runner (G) and hinge plates (D)
the reed is not kept sufficiently tight at the third pick. To ensure of an abso-
lute, locking we employ a further rod (0), and upon such rod we provide a series
of levers (P), all of which are keyed to the rod (0). To each lever we link a
finger (or latch) (Q), and each finger extends upwards through a fixed guide (R),
with one of its sides lying flush with the rear face of the sley as illustrated.
One (or more) of the said levers (P) is provided with an extension (P*) and
at the extremity of such extension is a runner (S). Upon the bar (H) are fur-
ther inclines (T) and (T). A spring (U) holds the levers (P) in the position
shewn in Fig. 1, which thereby causes such levers to hold the fingers (or
latches) (Q) in an elevated position directly behind the part (C) and thereby
securely lock the reed (see Fig. 1).
When the bar (H) is raised by the chain (M), or eccentric (N), and the
incline (T) brought into the path of the runner (S) the levers (P) are tilted,
the fingers (Q) lowered, and the reed unlocked (see Fig. 2).
To ensure of the reed being unlocked before the part (C) begins to open,
the runner (S) meets the incline (T) before the runner (G) meets the incline (J),
and the levers (P) are so proportioned as to give a comparatively quick action.
The links of the chain (M) may vary with the number of picks it is desired
to leave the reed unlocked.
When the eccentric (N) is used the arm (H) is held against it by a spring (V).
If desired we may dispense with inclines (I) and (T), but they are useful in
helping the springs (K) and (U).
By the use of the chain (M), and by the variation in the size and number
of its links, we may also provide for the closing of the reed when weaving plain
parts, the narrow links alternating with the wider links for the terry motion,
and a length of narrow links serving for the plain parts of the cloth.
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: In. looms for weaving terry and like fabrics, means for firmly locking
the reed at each third or other predetermined pick, substantially as and for
the purposes set forth.
