An Improved Take up Motion for Weaving Looms.
I, WILLIAM BEGG of 633 Springfield Road, Parkhead, Glasgow in the County
of Lanark, Wire-cloth Manufacturer, do hereby declare the nature of this invention
to be as follows
This invention relates to an improved take up motion applicable either to hand or
power weaving looms and the apparatus constituting the invention consists of two
brackets secured to opposite sides of the frame of the swinging lathe of the loom.
These brackets carry a screw which is turned as desired by a hand wheel or crank
and the said screw carries a nut to which is connected one end of a rod, cord or link the
other end of which is attached to one end of a lever whose opposite extremity is
centred on a stud or spindle carried in the framing of the loom or in separate brackets.
The stud or spindle also carries a friction wheel which has a V or other shaped
circumferential groove in its periphery with which a suitably shaped pawl centred on
the lever is placed in frictional contact. On the stud or spindle or on the side of the
friction wheel and concentric therewith a bevel wheel is secured the said wheel being
geared with a bevel pinion on one end of a short shaft or spindle whereon a worn
screw is also formed or fixed the said screw being geared with a worm wheel which
may either be secured or situated loosely on the axis of the beam or roller on which
the cloth as it woven is wound. When loose upon the said axis the wheel is geared
thereto as desired by a clutch or equivalent arrangement.
With the apparatus arranged as hereinbefore described in swinging the lathe the
lever hereinbefore referred to is by the contact of its pawl with the friction wheel
caused to turn the said wheel through an arc which has the effect through the bevel
and worm gearing of turning the cloth beam or roller and of winding the web upon
it. As the weaving proceeds and the diameter of the roll of cloth on the beam
increases the beam is caused to rotate at a slower rate by turning the screw carried by

page_text: the frame of the lathe so as to shift the position of the nut and cause the lever and
friction wheel at each swing of the lathe to move through a smaller arc.
In the event of the pawl carried by the lever coming or being brought out of
contact with the friction wheel, to prevent the said wheel from turning in the wrong
direction and so unwinding the web from the cloth beam or roller, a second pawl or
equivalent apparatus to prevent its rotation is provided in conjunction with the
friction wheel.

An Improved Take-up Motion for Weaving Looms.
1, WILLIAM BEGG of 633 Springfield Road, Parkhead, Glasgow, in the County of
Lanark, Wire-cloth Manufacturer 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 relates to an improved take-up motion applicable either to hand or
power weaving looms and as illustrated in side elevation by figure 1 of the accom-
panying drawings the apparatus constituting the invention consists of a bracket a
secured to the frame of the swinging lathe of the loom. The bracket carries a
screw c which is turned as desired by a hand wheel d or by a crank or its equivalent
and on the said screw there is placed a nut e to which is connected one end of a
rod or link the other extremity being attached to the outer ends of two levers g
which at their inner ends are centred on a stud or spindle h carried in the framing
of the loom or in separate brackets. Between the levers g there is secured on the
stud or spindle ha friction wheel having a V or other shaped circumferential
groove with which a pawl j centred on the pink connecting the link and
levers g together is placed in frictional contact.
Figure 2 is a side clevation and figure 3 an end elevation of the arrangement
drawn to a larger scale.
On the stud or spindle h or on the side of the friction wheel i and concentric
therewith a bevel wheel is secured and geared with a similar wheel in on one end of
a short shaft n whereon a worm screw n¹ is also formed or fixed the said screw being
geared with a worm wheel o which may either be secured or situated loosely on the
axis r of the beam or roller on which the cloth as it is woven is wound. When loose
the wheel o is connected to the beam or roller by a pawl p centred upon the wheel
and geared when required with a ratchet wheel 7 keyed on the axis r or by other
equivalent means.
With the apparatus arranged as described in swinging the lathe 6 the levers g, are
by the contact of the pawl with the friction wheel i, caused to turn the said wheel
through an are which has the effect, through the level and worm gearing, of turning
the cloth beam or roller and of winding the web upon it. As the weaving proceeds
and the diameter of the roll of cloth on the beam increases, the beam is caused to
rotate at a slower rate by turning the screw c so as to shift the position of the nut e
upon it and thereby to make the levers g and friction wheel i move through a smaller
arc at each swing of the lathe.
To prevent the friction wheel from turning in the wrong direction and so
unwinding the web from the cloth beam or roller, in the event of the pawl coming
or being brought out of contact with the wheel, a second pawls is provided in
conjunction with the said wheel as shewn on the drawings.

page_text: In some cases the screw c and nut e may be dispnsed with and a crank, having a
pin capable of being shifted to a greater or less distance from the centre, employed to
operate the link the said crank being actuated from any suitable rotary part of the
loom.
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 improved take up motion for weaving looms constructed and arranged
substantially as hereinbefore described with reference to the drawings annexed.
2. In a take-up motion for weaving looms the combination of the screw c, nut e,
link f, levers 9, wheel h, and pawls j, s, substantially as set forth with reference to
the appended drawings.
3. In a weaving loom the combination of the apparatus claimed under the second
claiming clause with the frame of the lathe, substantially as and for the purpose set
forth.
4. In a take-up motion for weaving looms the combination of the link f, levers g,
wheel hand pawls j, s substantially as described with reference to the drawings
annexed.
