Improvements in and relating to Machines for Raising and Dressing
Woven Fabrics.
I, CHARLES WOOD, of 64, Belmont Street, Heaton Norris, near Stockport, in
the County of Lancaster, Engineer, do hereby declare the nature of this invention
to be as follows:-
My invention relates to improvements in and in connection with the raising
rollers of machines for raising and dressing woven fabrics.
Prior to my present invention it has been the practice to fix the raising rollers
upon their shafts or axes but according to my improvements I employ hollow
raising rollers or cylinders and mount the ends of each hollow roller upon hubs
I secure to or form with each
or bosses which are loose upon the shaft or axle.
hub or boss an internally toothed wheel which gears into a pinion or any number
of pinions preferably two, each carried on a stud fixed on a disc or block fast
upon the roller shaft. The raising machine may be built up of any suitable
and convenient number of these raising rollers, and the shafts upon which
these rollers are placed loosely as described are driven say one half in one direc-
tion and the other half in the opposite direction.
The raising rollers are carried round by means of the internal gears meshing
into the loose pinions which revolve with the driven shafts, and the raising
action is obtained by guiding the cloth into contact with the raising rollers, and
by employing, when necessary, driving belts or ropes passing over or under the
peripheries of the internally toothed wheels.
In some cases I might employ only one set of gearing for each raising roller
instead of having internal gears at each end as described, and for very light
fabrics a driving belt or rope would not be required as the resistance of the
raising rollers would be sufficient without it.

and ascertained in and by the following statement:-
-
My invention relates to improvements in and in connection with the raising
rollers: of machines for raising and dressing woven fabrics.
Prior to my present invention it has been the practice to fix the raising rollers
upon their shafts or axes but according to my improvements I employ hollow
raising rollers or cylinders and mount the ends of each hollow roller upon hubs
or bosses which are loose upon the shaft or axle. I secure to or form with each
hub or boss an internally toothed wheel which gears into a pinion or any number
of pinions preferably two, each carried on a stud fixed on a disc or block fast
upon the roller shaft.
In the accompanying two sheets of drawings-
Figure 1 is a side elevation and Figure 2 a plan of a vertical raising machine
embodying my improvements, Figure 2 is a plan of one of the raising rollers
having its gearing at the opposite end to that shown in Fig. 2.
Figure 3 is a front elevation of part of the machine with some of the parts in
section.
Figure 4 is a plan taken on the line A, A Fig. 1.
Figures 5 and are detail views on an enlarged scale of the gearing for carry-
ing round the raising rollers.
In these views,-1 denotes the frame of the machine, 2 the driving shaft, 3, 4
fast and loose pulleys respectively, 5 the driving belt, 6 and 7 two pairs of grooved
driving pulleys, 8 and 9 driving bands, 10 grooved driving pulleys, 11 raising
roller shafts, 12 raising rollers with hubs or bosses 13, see Fig. 6, loose on the
raising roller shafts, 14 internally toothed wheels fixed on. the bosses of the
raising rollers, 15 pinions meshing into the internally toothed wheels and mounted
on studs 16 carried by blocks 17 fixed on the raising roller shafts.
The raising machine may be built up of any suitable and convenient number
of these raising rollers 12, and the shafts 11 upon which these rollers are placed
loosely as described are driven say one half in one direction and the other half
in the opposite direction. In the present example the machine is shown com-
posed of four raising rollers 12 arranged vertically with two of the raising roller
shafts 11 driven by the open and crossed bands 8 and 9 respectively from one
pair of grooved pulleys 6, while the other two raising roller shafts 11 are driven
by similar open and crossed bands from the pair of grooved pulleys 7 at the
opposite end of the shaft 2.
The raising rollers 12 are carried round by means of the internal gears 14
meshing into the loose pinions 15 which revolve with the driven shafts 11, "and
the raising action is obtained by guiding the cloth 18 into contact with the rais-
ing rollers 12, and by employing, when necessary, driven belts 19 or ropes
passing over or under the peripheries of the internally toothed wheels 14.
In the arrangement shown there are two driven belts 19 one a crossed belt
running from a pulley 20 on the driving shaft 2, round the internal gears 14
on two of the raising rollers 12, and the other an open belt 19 running from a
pulley 21 near the other end of the driving shaft 2 round the internal gears 14
on the remaining two raising rollers 12.
The drawings illustrate only one set of gearing for each raising roller 12 but
if preferred the internal gears might be duplicated and a set of similar gears
be placed at each end of each roller. Instead of employing two pinions 15 on
each block 17 a single pinion or three or more pinions might be employed.
Again, instead of using toothed wheels, friction gearing might be employed.
The cloth 18 is travelled in the usual way and guided into, through and out
of the machine in the direction indicated by the arrows in Fig. 1, and to lead
it into contact with the raising rollers 12 any suitable number of guide rods
or rollers 22 are employed each journalled in slide blocks 23 carried in brackets 24
and adjustable by means of screws and hand wheels 25.
The raising action of the rollers 12 is regulated to some extent as above stated

page_text: by guiding the cloth into more or less contact with the card wire or other
material forming the raising surface of the rollers; but the raising action is
still further regulated and increased or diminished at will by adjusting the ten-
sion of the driven belts 19 by means of tension pulleys 26, of which only one
is shown, each carried on a lever 27 controlled by a screw and hand wheel 28.
For very light fabrics the driven belts 19 would not be required as the resistance
of the raising rollers 12 would be sufficient without them.
Instead of mounting the raising rollers in a vertical frame as shown and
described they may be mounted in a horizontal frame or otherwise in any of
the known arrangements.
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. A raising roller mounted loosely upon its driven shaft or axle and geared
by an internally toothed wheel to say two pinious mounted on studs carried by
a disc or block fast upon the driven shaft of the raising roller substantially as
herein set forth.
2. A raising roller mounted loosely upon its driven shaft or axle and geared
by an internally toothed wheel to say two pinions mounted on studs carried by
a disc or block fast upon the driven shaft of the raising roller in combination
with a driven belt or rope in contact with the periphery of said internally toothed
wheel substantially as herein set forth.
3. The general combination and arrangement of parts constituting a machine
fitted with raising rollers constructed, arranged and operating substantially as
herein set forth.
