page_text: LETTERS PATENT to John Butterworth, William Dickinson, both of Burnley,
in the County of Lancaster, Machine Makers, and Christopher Catlow, of
Burnley, aforesaid, Overlooker, for the Invention of "IMPROVEMENTS IN
LOOMS FOR WEAVING."
Sealed the 6th January 1880, and dated the 11th July 1879.
PROVISIONAL SPECIFICATION left by the said John Butterworth, William
Dickinson, and Christopher Catlow at the Office of the Commissioners of
Patents on the 11th July 1879.
JOHN BUTTERWORTH, WILLIAM DICKINSON, both of Burnley, in the County of
Lancaster, Machine Makers, and CHRISTOPHER CATLOW, of Burnley, aforesaid,
Overlooker. IMPROVEMENTS IN LOOMS FOR WEAVING."
Our Invention relates, firstly, to an improved method and apparatus for working*
the healds.
"
Secondly. To improved apparatus for regulating the taking up action of the cloth
roller.
Thirdly. Improvements for strengthening the reed.
Fourthly. Improvements whereby the contraction or narrowing of the piece
being woven is prevented.
Fifthly. An improved weighting or turning off motion.
Sixthly. An eccentric boss for loose pulley to work in connection with eccentric
fixed or fast pulley.
Our Invention is as follows:-Firstly. Improved apparatus for regulating the
taking up of the cloth roller whereby a number of shafts can be employed.
On the crank shaft we fix a cam or eccentric which operates a lever (fulcrumed
to the back part of the loom side) and carries two vertical rods and a cross piece,
the treddle levers resting on the cross piece; on a stud under the treddle levers are
a corresponding number of bell cranks, levers, and projections, on the under side of
the treddle levers resting on the upper arms of the bell crank levers when the
treddles are lifted by the cam or eccentric. Attached to the other end of the bell
crank levers are blade springs which are acted upon by barrel or pattern mechanism
moving the upper bell crank arms in or out of contact with the treddles, according
Price Gidl

page_text: shart.
The-treddles are connected either to jacks or levers and bowls when jacks
are employed, and a double motion required, an ordinary treddle is employed
(under the loom), carrying the jacks, and operated by a double tappet on
the tappet shaft or eccentric on the crank shaft for carrying the healds. We
employ (instead of the usual quadrant levers with toothed connections) quadrant
levers connected by stud and slot from the arms of the quadrant levers; at right
angles are legs to which the springs are attached; by this arrangement equal
pressure is given the healds of the springs; for convenience and strength we find
_ two sets of levers-and-springs one above the other is best.
Secondly. For regulating the taking up of the cloth roller on the axis of the cloth
roller is the catch wheel and lever carrying two or more catches; to lower end of
the lever is attached another arm or lever on which is an open spiral spring, the
other end of the arm or lever working a slot on the slay sword; about midway its
length is a bracket or stud upon which the arm or lever rests; as the diameter of
the cloth roller increases it causes the end of the arm to rise in the slot, giving more
motion to the lever, compresses the spring on the arm, and increases pressure upon
the beam as the latter increases in diameter.
Thirdly. For strengthening the reeds instead of the ordinary dents at the ends of
the reeds,
We employ dents having back strengthening ribs and eyelets at top and bottom,
into which the beam ends of the reeds are fixed.
Fourthly. For preventing contraction or narrowing of the piece being woven,
we fix in the slay beam clear of the shuttle race, pins, staples, or bristles, which,
when the slay is back, the weft catches, and is drawn (towards each edge) out of
the straight line to an angle increasing the length of the weft, and thus preventing
narrowing or contraction of the piece and greatly facilitating the work of the
temples.
Fifthly. For weighting the warp beam, we employ the ordinary weights and
levers, chains, or ropes, around the ruffle of beam; instead of fixing the ends of
chains or ropes to spring or bracket we pass them around guide pulleys or runners,
and connect their ends; the ends of the weighting levers are also connected by link,
chain, or strap, so making the whole an endless connection, thus ensuring an equal
tension or drag on the beam as well as facilitating the lifting off the weights and
levers in turning back the slack warp, the weights on one lever counterbalancing
those on the other. When used as a turning off motion we connect rods from the
weighting levers to the vibrating back bar so as to give an alternate upward and
downward motion to the rods and levers.
Sixthly. We employ an eccentric boss on which the loose pulley is fixed, corre-
sponding with the eccentric_fixed_pulley.--

JOHN BUTTERWORTH and WILLIAM DICKINSON, both of Burnley, in the County
of Lancaster, Machine Makers, and CHRISTOPHER CATLOW, of Burnley, aforesaid,
Overlooker. "IMPROVEMENTS IN LOOMS FOR WEAVING."
This Invention relates, firstly, to an improved apparatus for working the
healds.
Secondly. To improved apparatus for regulating the taking up action of the cloth
roller.
Thirdly. Improvements for strengthening the reed.
Fourthly. Improvements whereby the contraction or narrowing of the piece being
woven is prevented.
Fifthly. An improvement weighting or turning off motion.
Sixthly. An eccentric boss for loose pulley to work in connection with eccentric
fixed or fast pulley.
Firstly. Our Invention comprises improved apparatus for working the healds,
whereby a number of shafts can be employed. On the crank shaft we fix a cam or
eccentric which operates a lever (fulcrumed to the back part of the loom side) and
carries two vertical rods and a cross piece, the treddle levers resting on the cross
piece; on a stud under the treddle levers are a corresponding number of bell crank
levers and projections on the under side of the treddle levers resting on the upper
arms of the bell crank levers when the treddles are lifted by the cam or eccentric.
Attached to the other end of the bell crauk levers are blade springs which are acted
upon by barrel or pattern mechanism moving the upper bell crank drums in or out of
contact with the treddle, according to the pattern on the barrel; the barrel is actuated
by pinion wheel on the tappet shaft. The treddles are connected either to jacks or
levers and bowls; when jacks are employed and a double motion required, an
ordinary treddle is employed (under the loom) carrying the jacks, and operated by
a double tappet on the tappet shaft or eccentric on the crank shaft for carrying the
healds. We employ (instead of the usual quadrant levers with toothed connections)
quadrant levers connected by stud and slot from the arms of the quadrant levers;
at right angles are legs to which the springs are attached; by this arrangement
equal pressure is given the healds by the springs; for convenience and strength we
find two sets of levers and springs, one above the other is best.
Secondly. For regulating the taking up of the cloth roller, on the axis of the
cloth roller is the catch wheel lever carrying two or more catches. To lower end of
the lever is attached another arm or lever on which is an open spiral spring, the
other end of the arm or lever working in a slot on the slay sword; about midway
its length is a bracket or stud upon which the arm or lever rests. As the diameter
of the cloth roller increases it causes the end of the arm to rise in the slot, giving
more motion to the lever, compresses the spring on the arm and increases pressure
upon the beam as the latter increases in diameter.
Thirdly. For strenghting the reeds instead of the ordinary dents at the ends
of the reed we employ dents having back strenghting ribs and eyelets at top and
bottom into which the beam ends of the reeds are fixed.
Fourthly. For preventing contraction or narrowing of the piece being woven.
We fix in the slay beam, clear of the shuttle race, pins, staples, or bristles, which,
when the slay is back the weft catches, and is drawn (towards each edge) out of the
straight line to an angle, increasing the lenght of weft and thus preventing
harrowing or contraction of the piece and greatly facilitating the work of the
emples.
Fifthly. For weighting the warp beam we employ the ordinary weights and
evers, chains, or ropes, around the ruffle of beam instead of fixing the ends of

page_text: chains or ropes to spring or bracket; we pass them around guide pulleys or bell
cranks and connect their ends by rod; the ends of the weighting levers are also
connected by link, chain, or-strap; so-making the whole-an-endless-connection,-thus
ensuring an equal tension or drag on the beam as well as facilitating the lifting of
the weights and levers in turning back the slack warp, the weights on one lever
counterbalancing those on the other; when used as a turning off motion we connect
rods from the weighting levers to the vibrating back bar so as to give an alternate
-upward-and-downwards-motion.to.the.rods and levers.
Sixthly. We employ an eccentric boss on which the loose pulley is run, corre-
sponding with the eccentric fast pulley.
Such being the nature and object of this our said-Invention-we will.now_proceed
to describe the particulars thereof, and in order that the Invention, may be fully
understood, we have hereunto annexed two Sheets of Drawings illustrating the
same, and have marked the several views with Figures of reference.
DESCRIPTION OF THE DRAWINGS.
On the
Figs. 1 and 2 shew the improved apparatus for working the healds.
crank shaft we fix a cam or eccentric I which operates a lever 2 (fulcrumed to the
back part of the loom side) and carries two vertical rods 3, 3, and a cross piece 4,
the treddle levers 5, 5, resting on the cross piece 4; on a stud under the treddle
levers are a corresponding number of bell crank levers 7 and projections 8, 8, on
the under side of the treddle levers resting on the upper arms of bell crank levers 7,
7, when the treddles are lifted by the cam or eccentric I. Attached to the other
end of the bell crank levers 7 are blade springs 9 which are acted upon by barrel
or pattern mechanism 10 moving the upper bell crank drum in or out of contact
with the treddles, according to the pattern on the barrel, the barrel 10 is actuated
by wheels 11, 12.
The treddles are connected either to jacks or levers and bowls; when jacks are
employed and à double motion required an ordinary treddle is employed (under
the loom), carrying the jacks and operated by a double tappet, such as 14, on the
tappet shaft or eccentric on the crank shaft. At Fig. for carrying the healds are
quadrant levers 15 connected by stud 15ª and slot 15b; at 16 are legs to which the
springs 17 are attached; by this arrangement equal pressure is given the healds
by the springs. For convenience and strenght we find two sets of levers and
springs one above the other is best.
At Fig. 4 is a modification in which the springs 17 and connections work over
studs or guide pulleys 18 carried by cross T head attached to the loom top.
Secondly. For regulating the taking up of the cloth roller, Fig. 5, on the
access of the cloth roller 1 is the catch wheel 2 and a lever 3 carrying two or more
catches 4. To lower end of the lever 3 is attached another arm or lever 5 on which
is an open spiral spring 6, the other end of the arm or lever 5 working in a slot on
the slay sword 1; about midway its lenght is a bracket or stud 8 upon which the
arm or lever 5 rests. As the diameter of the cloth roller increases it causes the
end of the arm 5 to rise in the slot 7, giving more motion to the lever 3, and com-
presses the spring 6 on the arm 5 and increases pressure upon the beam as the
Jatter increases in diameter.
Fig.6 is a modification in which there is a link 1 on axle of the cloth roller 2,
from thence a chain 3 passed once or twice around a boss 4 on the axle taking up
beam; to the lower end of the chain is attached the weight; the boss 4 has an arm
5 and spring 6, the latter resting against the frame work of the loom so as
to compensate for any inequalitys or uneveniness in the beam and taking up
roller.
Thirdly. For strenghting the reeds, Fig. 7, instead of the ordinary dents at the
ends of the reed we employ dents 1 having back strenghting ribs 2 and eylets
3, 3, at top and bottom, into which the beam ends of the reeds are fixed.
Fourthly. For preventing contraction or narrowing of the piece being woven

page_text: Fig. 8, we fix in the slay beam, clear of the shuttle race, pins, staples, or bristles,
which, when the slay is back, the weft 4 catches, and is drawn (towards each edge)
out of the straight line to an angle increasing the lenght of weft, and thus pre-
venting narrowing or contraction of the piece and greatly facilitating the working
of the temples.
Fifthly. Fig. For weighting the warp beam, Fig. 9, we employ the ordinary
weights and levers 2, chains or ropes around the ruffle of beam; instead of fixing
the ends of chains or ropes to spring or bracket we pass them around guide pulleys
or bell cranks 3, and connects their ends by rod 4; the ends of the weighting levers
are also connected by link, chain, or strap 5, so making the whole an endless con-
nection, thus ensuring an equal tension or drag on the beam, as well as facilitating
the lifting of the weights and levers in turning back the slack warp, the weights on
one lever counterbalancing those on the other when used as a turning off motion, see
Figs. 10 and 11. We connect rods I from the weighting levers to the vibrating
back bar 3 so as to give an alternate upward and downwards motion to the rods and
levers; the warp, as shewn, passes from the beam 4 over the bar 5 to and over the
vibrator 3.
Sixthly. We employ an eccentric boss 1, Fig. 12, on which the loose pulley 2
is run, corresponding with the eccentric fast pulley described in Specification of
former Patent.
Having thus fully described and ascertained the nature and particulars of this
our Invention, we claim,-
Firstly. The combination and arrangement of apparatus for 'working the healds
or treddles, as by shewn Figs. 1 and 2.
Secondly. The combination of levers 15 having slots, studs, legs 16, and springs
17, as illustrated at Fig. 3, and also the modification shewn by Fig. 4.
Thirdly. The arrangement and combination of parts, shewn by Figs. 5 and 6, for
taking up the cloth as woven.
Fourthly. We claim the construction of reed as described and illustrated at
Figs. 7.
Fifthly. We claim the combination and arrangement of parts for weighting and
for letting off the yarn as described and illustrated by Figs. 9, 10, and 11.
Sixthly. The appliances for preventing the contraction of the piece during
weaving, as described and illustrated by Fig. 8.
Lastly. The eccentric boss for loose pulley in combination with an eccentric fast
pulley, as described and illustrated by Fig. 12.
In witness whereof, I, the said Christopher Catlow, for and on behalf of
myself and the said John Butterworth and William Dickinson, have here-
unto set my hand and seal, this Seventh day of January, in the year of our
Lord One thousand eight hundred and eighty.
