Improvements in Taking up and Reversing Motions of Looms
for Weaving.
I, JOHN LEEMING of North Vale Works Bradford in the County of York Machine
Maker, do hereby declare the nature of this invention to be as follows:-
:-
.
This invention relates to apparatus for taking up the cloth as woven and consists of
an improved combination of mechanism for operating the taking up roller and for
effecting the reversal of the machine and roller when requisite.
According to this my invention I apply to the tappet shaft a bevel wheel which
gears with and drives a like wheel on a side shaft preferably inside the loom framing,
the said shaft carries a worm gearing with a worm wheel, the latter driving the spur
wheels of the taking up roller.
The shaft is supported in brackets secured to the loom framing, the end bracket
having a loop or eye in lower part of which the shaft rests. When necessary to
reverse for a considerable number of picks the end of the worm shaft can be lifted
in its looped bracket raising the worm out of gear with the wheel so facilitating
reversal.
For effecting the mechanical reversal of the loom and in combination with the
mechanism already described I employ a grooved pulley attached to or forming part
of the boss of the loose pulley on the crank shaft a corresponding pulley is placed on
the tappet shaft, a third pulley the periphery of which is formed to correspond with
and fit into the grooves in the two pulleys referred to is mounted loosely on a lever
controlled by treadle or hand rod.
When the loom is to be reversed the strap on being transferred to the loose pulley
revolves that pulley, and also the grooved pulley connected therewith. If then the
intermediate pulley on the treadle or hand lever he brought into contact with the
grooved pulleys, on the crank and the tappet shafts, the loose pulley becomes the driver
of the tappet shaft and the loom reversed so long as the contact of the grooved pulleys
is maintained.

Improvements in Taking up and Reversing Motions of Looms
for Weaving.
I, JOHN LEEMING of North Vale Works, Bradford in the County of York, Machine
Maker, 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 apparatus for taking up the cloth as woven, and consists of
an improved combination of mechanism for operating the taking up roller and for
effecting the reversal of the loom and roller when requisite.
According to this my invention I apply to the tappet shaft a bevel wheel which
gears with and drives a like wheel on a side shaft preferably inside the loom framing,
the said shaft carries a worm gearing with a worm wheel the latter driving the train
of wheels of the taking up roller.
The shaft is supported in brackets secured to the loom framing, the end bracket
having a loop or eye in lower part of which the shaft rests. When necessary to
reverse for a considerable number of picks, the end of the worm shaft can be lifted
in its looped bracket, raising the worm out of gear with the wheel so facilitating
reversal.
. For effecting the mechanical reversal of the loom and in combination with the
mechanism already described, I mount on the crank shaft and also on the tappet two
grooved friction pullies, a third pulley the periphery of which is formed to correspond
with the grooves of the pullies referred to I mount on a lever controlled by treadle
or hand rod so that when the said pulley is forced between the two grooved pullies
the motion of the loom is reversed so long as contact of the three pullies is
maintained.
Such being the nature and object of this my invention the following is a complete
description of same reference being had to the accompanying drawings:
Fig. 1 (sheet 1) is a side elevation of the "taking up" roller motion.
Fig. 2 (sheet 1) is an end elevation of Fig. 1.
Fig. 1 (sheet 2) is a side elevation of my improved reversing motion.
Fig. 2 (sheet 2) is an end elevation of Fig. 1 (sheet 2).
According to this my invention I apply to the tappet shaft 1 a bevel wheel 2 which a
gears with and drives a like wheel 3 on a side shaft 4, preferably inside the loom
framing 5, the said shaft 4 carries a worm 6 gearing with a worm wheel 7 the latter
driving the chain of wheels 8, 9, 10 of the taking up roller 11.
The shaft 4 is supported in brackets 12, 13 secured to the loom framing 5, the end
bracket 12, having a loop or eye 14 in lower part of which the shaft 4 rests.
When necessary to reverse for a considerable number of picks, the end of the
worm shaft 4 can be lifted in its looped bracket 12 raising the worm 6 out of gear
with the wheel 7; so facilitating reversal; 15 is a spring for holding the shaft 4 in the
bottom of the slot 14 when in working position.

page_text: For effecting the mechanical reversal of the loom, and in combination with the
mechanism already described, I mount on the crank shaft 17, and also on the tappet
shaft 16, grooved friction pulleys 18, 19, a third pulley 20, (the periphery of which is
formed to correspond with the grooves of the pulleys 18, 19) is mounted on the
lever 21, and controlled by treadle or hand rod 22, so that when the pulley 20, is
forced between the pullies 18, 19, the pulley 19, being fast on the boss 18°, of the
loose pulley 18b, the latter, so long as 20 is in contact with 18 and 19, converts the
loose pulley 18°, into a driving pulley, and the motion of the loom is reversed.
I prefer to use in conjunction with the arm 22b, of the handle 22, a holding catch,
or a treadle motion, for unlocking the part 22b, prior to operating the handle 22, such
device is not absolutely necessary, but it is a precaution against improperly timed
use of the handle 22.
Having now particularly described, and ascertained the nature of my said Inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is
1. The construction, arrangement, and combination of parts, for operating the taking
up roller 11, as herein described, and illustrated by annexed drawings.
2. The mechanism on sheet 2, for reversing the loom, in combination with the
mechanism for operating the taking up roller 11, as illustrated on sheet 1.
