Improvements in Fulling and Milling Machines.
I SAMUEL TURNER of Windsor Street Rochdale in the County of Lancaster,
Mill Mechanic, do hereby declare the nature of this invention to be as follows:-
My invention relates to fulling and milling machines.
My improvements have particular reference to the mechanism for operating the
pressure roller of such a machine. I am enabled by my arrangement to dispense
with the gearing now employed in connection with and for operating the pressure
rollers of such machines. It is well known that the. cloth, when passing to the
pressure roller is frequently damaged, when such gearing is employed, which may
and does occur in consequence of the material or cloth being operated upon in the
machine accumulating between the pressure roller and the driving or bottom
roller, consequently upon the happening of such an event, the pressure roller is
frequently thrown out of, or partially thrown out of gear with the gear wheel on
the driving shaft, consequently upon the happening of such an event, the pressure
roller may cease to revolve altogether, or the roller may revolve partially or
irregularly, consequently the dislocation or partial dislocation of such parts result
in the cloth being fed to or carried on to the pressure roller, such roller under
these circumstances being unable to perform its functions, hence the accumulation
and damage to the cloth, as the nap of the cloth may be rubbed off, or the cloth
may be cut at such part, by the stationary position or irregular action of the
pressure roller as the case may be.
I
By the use of my improvements I claim that such damage arising from the causes
before named will be obviated. I also claim that great economy will be effected
in the cost of recovering or what is known as "recogging" the pressure roller.
will now proceed to describe by what means my invention is carried into effect.
According to my arrangement I mount on the shaft of the driving roller a grooved
pulley, and at a convenient distance therefrom I provide or fix two grooved carrier
pullies mounted on the stud of a bracket or sliding piece, situated in a slide piece
or guide which stud is capable of adjustment more or less to or from the driving
shaft, and is effected by means of a suitable screw threaded piece or
66 screw."
also mount on the shaft of the upper or pressure roller a grooved pulley. Motion
is imparted from the driving shaft to the pressure roller by means of a rope
(endless) cord or band, which is conveniently placed thereon in a certain manner
from the driving pulley to the pulley on the pressure roller shaft, the adjustable
carrier pullies before referred to, intercepting the said band between its extremities,
and carrying the said band, thus the tension of the band may be thereby effected
and maintained, thus the positive driving of the pressure roller may be attained and
ensured. If desirable I may employ pullies having two or more grooves in order
to admit of the employment of two or more ropes, thus to further ensure positive
driving or motion of the pressure roller, as may in certain cases be necessary.
It will be manifest that by the use of the arrangement above described, in the
event of the pressure roller being raised, from the causes before described, the said
roller notwithstanding such occurrences, will continue to revolve, as the rope or
ropes will rise and fall with the roller, consequently damage or cutting of the cloth,
will be obviated, also the pressure roller being allowed to fall without hindrance
or obstruction, as is the case when gearing is employed, admits of the wood
covering, cogs, or sheathing being fully utilised or worn out before renewal is
ecessary.

Improvements in Fulling and Milling Machines.
I SAMUEL TURNER of Windsor Street Rochdale in the County of Lancaster
Mill Mechanic, 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 :-
My invention relates to fulling and milling machines.
My improvements have particular reference to mechanism for operating the
pressure roller of such a machine.
I am enabled by the use of my arrangement to dispense with gearing or spur
toothed wheels as now employed in connection with and for operating the pressure
rollers of such machines.
It is well known that the cloth when passing to the pressure roller is frequently
damaged by such roller where gear or tooth wheels are employed, which may and
does occur in consequence of the material or cloth being operated upon or treated
in the machine accumulating or gathering between the pressure or upper roller and
the driving or lower roller, consequently upon the happening of such an event the
gear or tooth wheel on the shaft of the pressure roller is frequently thrown out of
gear with relation to the corresponding gear wheel on the shaft of the lower roller,
which shaft is the driven or first motion shaft; or the said tooth wheels may only
be partially in gear obviously on the happening of such occurrences the pressure
roller may cease to revolve, or the said roller may revolve only partly or at inter-
mittent or irregular periods, upon the happening of either event the cloth being
fed or carried on to the pressure roller the said roller in the one case remaining
stationary, in the other case rotating irregularly, thus under such circumstances it
is unable to perform its proper function, hence the accumulation and consequent
damage to the cloth as the nap of the cloth in the former case may be rubbed or
shorn off, in the latter event, the cloth may be cut.
By the use of my improvements I claim that such damage arising from the before
named causes may be obviated.
I also claim that economy will be effected in the cost of recovering or what is
known as 66
re-cogging" the pressure roller.
In order that my invention may be better understood I have hereunto annexed
two sheets of drawings in which like letters of reference indicate like or similar
parts throughout the figures therein shewn.
Fig. 1. is an elevation shewing the application of my invention illustrating only
so much of the parts of a milling machine as is necessary for a clear comprehension
of this my invention.
Fig. 2. is a plan drawn to a smaller scale than the preceding figure shewing the
position or threading of the endless rope or driving band on the pullies.
Fig. 3. is a plan of Fig. 1.
According to my construction or arrangement I mount on the driving shaft A.
being the shaft on which the lower roller B is mounted or by which it is carried, a
double grooved pulley or two single pullies C. C', at a convenient distance there-
from preferably to any convenient part of the framework of the machine I provide
grooved carrier pullies D. D' which pullies are supported on a stud E, carried by a
bracket F, having a slot F in which a slide piece G is situate and to which the
stud E is attached; through the said slide piece G passes a screw threaded rod H.
which extends the length of the slide or guide F¹ being provided at the end or
extremity extending out of the guide or slide with a hand wheel I.
On the upper or pressure roller shaft J' I mount a double grooved pulley or two
grooved pullies J. J. I place on the pullies an endless rope or hempen driving
band K. being threaded or placed thereon in the manner as more particularly shewn
in Fig. 2.
I would have it understood that I may if desired employ on the shafts J³ and A

page_text: one or more pullies or pullies having one or more grooves with the corresponding
number of carrier pullies accordingly as may be necessary to adapt my arrangement
for operating machines in cases where greater or less driving power may be required
and as the case may be, in the drawings hereunto annexed it will be observed that I
have illustrated the employment of two or double grooved pullies thus in this case
double rope driving is exhibited.
The action or operation of and the application of the endless driving band or rope
is as follows. In order to explain the threading or application of the rope or band
on the pullies I will commence with pullies J J' on the shaft J³ tracing from the
point L. see Fig. 1.
The double rope K passes in direction from the pullies J. J' see Figs. 2. and 3,
to carrier pullies D. thence to the underside thereof continuing to the underside of
the pullies C. C¹ passing over the semi-circumference of the same at C² see Fig. 1.
to the upper part thence crosses or passes over to the underside of the carrier
pullies D then extends around the semi-circumference at D" passing over the
upper part of the said pullies thence passes to the underside of the pullies J. J1
passing around the semi-circumference at J2 to the upper part to the point L thus
the circuit of the band is complete.
The endless band or rope being placed in position as hereinbefore described the
same may be stretched more or less or a greater or less tension effected in order to
ensure a firm grip or adhesion of the band with the rims of the pullies by means of
the adjustable carrier pullies actuated by the screw-threaded rod, thus positive
driving of the pressure roller may be accomplished.
The pressure roller being driven by means of the endless band, the said roller is
capable of and is allowed to rise and fall, as the portion of the band intercepting
the upper pullies J J and the carrier pullies are capable of angular movements,
with relation to the fixed centre or axis of the carrier pullies and during such.
movement the rotation thereof not being interfered with or impeded, consequently
in the event of an increase of mass or accumulation of material between the
rollers M and B. the cloth is allowed to pass on uninterruptedly or without
hindrance the pressure roller M adjusting itself to the varying circumstances,
consequently the evils-cutting or damaging the cloth-attendant in machines in
which gear or tooth-wheels are employed are thus obviated; also the sheathing, or
covering of the upper roller may be worn down or utilised to its maximum limit, as
the periphery thereof according to my arrangement (when the machine is not in
use) may be and are always in contact with the periphery of the lower roller, such
contact not being prevented as the roller wears, as is the case when gear or tooth-
wheels are employed.
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. In combination one or more adjustable pullies D D¹; pullies J. J¹ and C. C'
the endless driving band K substantially as and for the purposes herein fully set
forth and described in the drawings hereunto.
2. In combination the band driven pullies J and C. having one or more grooves as
and for the purposes herein fully set forth.
3. The band driven pulley J. having one or more grooves on the pressure roller
shaft and the carrier pullies whereby the pressure roller M is capable of rising and
falling whilst the said roller is capable of continuing its rotation notwithstanding
such rising and falling action or motion as fully set forth in the drawings hereunto
annexed.
4. A band driven pulley J. as and for the purposes herein fully set forth.
