PROVISIONAL SPECIFICATION.
Automatically Operating and Regulating Warp Beams employed in
Looms for Weaving.
I, JAMES COLLIER of 171 Egerton Street, Moses Gate near Bolton in the
County of Lancaster, Engineer, do hereby declare the nature of my said invention
to be as follows:-
This invention relates to automatically operating and regulating warp beams
employed in looms for weaving and consists in providing mechanism for differentially
operating the same to deliver yarn at an uniform speed whatever diameter the yarn
beam may be. This I accomplish by providing the warp beam shaft or centre with
a worm wheel operated by a worm mounted on a shaft driven by spur gear and a
ratchet wheel rotated by one or more "pawls" attached to a reciprocating arm or
lever. The latter is mounted on a shaft in suitable bearings secured to any
convenient part of the loom. The shaft carrying the "pawl" lever is fitted with
an adjustable arm or lever, and the latter is operated each pick by a movable
inclined plane mounted on a shaft rotated by bevel or other gear from the weft
motion shaft, tappet shaft, or any other convenient rotating part of the loom. The
inclined plane is slid on its supporting shaft by a fork attached to a rod carrying a
bowl or roller. The latter operates against the yarn on the warp beam, and is held
thereto by a weight and strap or chain passing over a pulley, or by a spring, or
other equivalents. When the yarn beam is full the adjustable arm or lever is
operated by the small end of the inclined plane, and as the yarn beam decreases in
diameter the fork slides the inclined plane so as to give the ratchet wheel an
increased motion, thereby rotating the yarn beam so as to give an uniform quantity
of yarn each pick throughout from full to empty beam. Means are provided for
re-setting the ratchet wheel and the adjustable arm or lever to their normal position
ready for each pick. Suitable arrangements are provided for altering or setting
the adjustable arm or lever according to requirements. A break is provided to
ensure of the apparatus being rotated in the right direction, also means for turning
the apparatus backwards if necessary.

Automatically Operating and Regulating Warp Beams employed in
Looms for Weaving.
I, JAMES COLLIER of 171 Egerton Street, Moses Gate near Bolton in the
5 County of Lancaster, Engineer, do hereby declare the nature of my said 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 relates to automatically operating and regulating warp beams
employed in looms for weaving and consists in providing mechanism for differentially
O operating the same to deliver yarn at an uniform speed whatever diameter the yarn
beam may be. This I accomplish by providing the warp beam shaft or centre with
a worm wheel operated by a worm mounted on a shaft driven by spur gear and a
ratchet wheel rotated by one or more "pawls" attached to a reciprocating arm or

page_text: lever. The latter is mounted on a shaft in suitable bearings secured to any
convenient part of the loom. The shaft carrying the "pawl" lever is fitted with
an adjustable arm or lever, and the latter is operated each pick by a movable
inclined plane mounted on a shaft rotated by bevel or other gear from the weft
motion shaft, tappet shaft, or any other convenient rotating part of the loom. The
inclined plane is slid on its supporting shaft by a fork attached to a rod carrying a
bowl or roller. The latter operates against the yarn on the warp beam, and is held
thereto by a weight and strap or chain passing over a pulley, or by a spring, or
other equivalents. When the yarn beam is full the adjustable arm or lever is
operated by the small end of the inclined plane, and as the yarn beam decreases in
diameter the fork slides the inclined plane so as to give the ratchet wheel an
increased motion, thereby rotating the yarn beam so as to give an uniform quantity
of yarn each pick throughout from full to empty beam. Means are provided for
re-setting the ratchet wheel, and the adjustable arm or lever to their normal
position ready for each pick. Suitable arrangements are provided for altering or
setting the adjustable arm or lever according to requirements. A break is provided
to ensure of the apparatus being rotated in the right direction, also means, for
turning the apparatus backwards if necessary.

Fig. 7 is a side view of break.
In all the figures the same letters are employed to indicate corresponding
parts.
On the loom side A is mounted the warp beam B, the shaft or centre C of which
is fitted with the worm wheel D operated by the worm E on the shaft G. The
latter is mounted in the bearings F secured to the loom side A. On the opposite
end of the shaft G is fixed the spur wheel H, which is rotated by the spur
wheels I, J, K, L, and M mounted on shafts or centres secured to the loom side A
in any convenient manner. The spur wheel M gears with the spur pinion N
mounted on the centre O attached to the reciprocating arm or lever P secured to
the boss Qon, the shaft R mounted in the bearings S attached to the loom side A.
The upper end of the reciprocating arm or lever P is constructed as shown to
carry two sets of "pawls "T secured thereto by the pins or centres U. Each
"pawl" is constructed of several thin levers of varying lengths to ensure of them
operating with the ratchet wheel V with a minimum of slip or loss of gripping
power. The ratchet wheel V is mounted on the centre O and attached to the
pinion N to ensure of the same operating together. The boss Q on the shaft R
carrying the "pawl" lever Pris fitted with the lever W to which is secured the
adjustable arm or lever ✗; the latter being operated each pick by the movable
inclined or other plane Y mounted on the shaft Z, actuated by the lever a from the
'slay' sword or any other convenient part of the loom. The inclined or other
plane Y is slid on its supporting shaft Z by the fork k attached to the rod b
carrying the presser c, which may be substituted by a bowl or roller, to operate
against the yarn on the warp beam B, which is held thereto by the weight a, and
chain e, the latter passing over the pulley f mounted on the centre 9 secured to the
frame A of the loom. The chain e is secured to the rod 6 by the arm h.

"
This apparatus operates in the following manner:When the yarn beam B is full
of yarn the inclined or other plane Y is in such a position that the small end operates
on the arm or lever X and pushes the lever W back and rocks the boss Q and

page_text: "pawl" lever P. When the lever a is raised by the action of the "slay" sword
each pick the "pawl" lever P is pushed back which allows the pinion N to rotate
the wheel M, this being caused through the ratchet wheel V being arrested by the
"pawls" T, which action operates all the gear and rotates the yarn beam.B sufficiently
to give off the requisite quantity of yarn. When the lever a is depressed the
lever P returns to its original position ready for the next pick. When the lever P
is returning to the latter position the spur pinion N rides on the wheel M without
operating the same the "pawls" T allowing the ratchet wheel V to rotate with it.
As the diameter of the yarn beam decreases the presser c follows up by the action
of the weight d which slides the inclined or other plane Y so as to give a greater
stroke to the lever P which will cause the gear to be rotated in proportion and so
on, the same automatically regulating itself so as to give an uniform quantity of
yarn each pick from full to empty beam. The slot in the lever W is provided to
allow of the lever X being altered so that the picks can be adjusted without
altering change pinion. To ensure of the apparatus moving in the right direction
and to prevent the gear being operated when the lever P is making a backward
stroke the wheel M is fitted with the brake pulley 1 against which operates the
brake lever m. The latter is pivoted to the loom side A by the centre n; and is
pressed against the brake pulley by the weight o.
This apparatus dispenses with the old system of regulating warp beams by levers,
ropes, chains, and weights, thereby effecting a great saving.
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 :-
1. The general arrangement, construction, and combination of apparatus for
automatically operating and regulating the delivery of yarn from warp beams
employed in looms for weaving at an uniform rate each pick from full to empty
beam, substantially as described and as illustrated in the annexed drawings.
2. In combination with apparatus for automatically operating and regulating
the delivery of yarn from warp beams at an uniform rate from full to empty
beam the use of the sliding and reciprocating inclined or other plane, substantially
as described.
