Improvements Appertaining to Spinning, Twisting and like Machinery
used in the Treatment of Fibrous Substances.
I, WILLIAM STELL of the firm of Hall and Stells of Keighley in the County of
York, Machine Makers, do hereby declare the nature of this invention to be as
follows:-
That is to say It relates firstly to an improved formation of bearing for
supporting the shafts of the driving cylinders or pulleys in spinning, twisting and
like machinery whereby perfect lubrication of these parts is secured and that with
little attention, on the part of the overlooker, being required.
To attain this object I make the bearing referred to so that an oil tank or box is
formed around same and in appropriate proximity therewith so that I am enabled
to mount a disc on the cylinder's shaft to dip into the oil in this box or tank.
The covering part of the bearing is made to receive a suitably formed scraper
which is binged thereto and arranged to fall into contact with the rotary disc from
which it scrapes or causes to flow, any lubricant that has been raised by it. This
flowing lubricant is guided and caused to enter openings made in the cover above
described from whence it falls on to the shaft in the bearing beneath.
The whole of the box or tank and bearing are formed so that an outer cover
(which may or may not be secured by screws &c.) may entirely enclose them and by
this cover being made dust proof the lubricant within is kept clean and serviceable
for a considerable length of time,
The second part of this invention relates to stop-motion mechanism to be used in
connection with spinning machinery known as "trap-twisters."
As is well known on these machines being put into motion it is necessary to
hold the trap levers in a certain position until said machines have approximately
reached their normal rate of speed, when said levers are released to perform the
functions desired of them, while when the motion of the said machines is being
arrested by the shifting of the driving belt in the opposite direction to that when
starting the same, these levers are desired to be similarly held and ma main-
tained until their services are required as before..
To provide means that will perform these functions automatically as the machines
are being put into and out of operation and that by the employment of simple and
not intricate and complicated parts is the object of this invention.
In carrying my invention into effect I make use of the sliding block usually used
and operated by the screw and hand-wheels employed in all cases in this class of
machinery for shifting the driving belt in both directions, however I couple this
sliding block to a lever by means of a suitably slotted connecting rod so that when
a certain part of the path of motion of this blook has been reached, the rod will
cominence to transmit its motion to this lever, the other arm of which is arranged
to operate against an incline forming the outer end of a lover secured to the usual
rocking shaft to which the trap levers herein before described are coupled to be raised
in the well known mauner.
As the block continues to move it carries with it this lever by pressing on its

page_text: inclined part until it raises it to the desired position for moving the rocking shaft
as far as is required on which its operating lever passes under its outer end and
retains it in this said desired position. All these movements being performed as
the block is being moved to arrest the motion of the inachine.
When the block is slided to start the machine, the inclined lever is still retained
in position by reason of the end of the slot in the slotted rol not being reached until
the desired time, on which the lever is again moved and in the opposite direction so
that the inclined lever is then allowed to descend and the rocking shaft thus to move
to act upon the trap levers as is uccessary.

Improvements Appertaining to Spinning, Twisting and like Machinery
used in the Treatment of Fibrous Substances.
I, WILLIAM STELL of the firm of Hall and Stells of Keighley in the County of York,
Machine Makers, do hereby declare the nature of this invention and in what
manner the same is to be performed, to he particularly described and ascertained
in and by the following statement:―
That is to say:-It relates firstly to an improved formation of bearing for
supporting the shafts of the driving cylinders or pulleys in spinning, twisting aud
like machinery whereby perfect lubrication of these parts is secured and that with
little attention on the part of the overlooker being required.
The second part of my invention relates to stop-motion mechanism to be used in
connection with spinning machinery known as "trap-twisters."
In order that my invention may be readily understood I have hereunto appended
sheets of drawings illustrative thereof to which by figures and letters reference is
made in the following description.
Figs. 1 and 2 are sectional side and end elevations respectively of a sufficient
portion of a driving cylinder to show the application thereto of my improved
lubricating device.
Fig. 3 is end elevation of part of a twisting frame as seen from outside the
framework, and illustrates the application of my improved stop-motion mechanism.
Fig. 4 is a view of the parts shown by fig. 3 but as seen from above.
Fig. 5 is a sectional end elevation of certain of the parts as seen in the opposite
direction to that in which fig. 3 is seen.
Fig. 6 is a sectional front elevation of certain of the parts shown by figs. 3, 4
and 5.
Fig. 7 is a drawing in detail illustrating parts shown by fig. 4 in altered positions.
To attain the object of the first part of my invention I make the bearing a so that
an oil tank 6 is formed around same and in appropriate proximity with the shaft
so that I am enabled to mount a disc or flange d on said shaft c to dip into the oil
or lubricant in the box or tank b.
The covering part al is made to receive a suitably formed scraper c which is
mounted therein and arranged to fall into contact with the rotary disc from which
it scrapes or causes to flow any lubricant that has been raised by said disc d. The
flowing lubricant is guided to fall on to the shaft o in the bearing a beneath.
The whole of the box or tank 6 and its bearing a are well protected by

page_text: the cover a which is made to fit all the parts so that no openings are left for the
accumulation of dust or dirt by which means the lubricant within is kept clean and
Berviceable for a considerable length of time.
Respecting the second part of iny invention it is well known that on the machines
known as *
trap-twisters" being put into motion it is necessary to hold each trap
lever in a certain position until said machines have approximately reached their
normal rate of speed, on which said levers are released to perform the functions
desired of them, while when the motion of the said machines is being arrested by the
shifting of the driving belt in the opposite direction to that in which it is moved
when starting said machines, these levers are desired to be similarly held and
maintained until their services are required as before.
To provide means that will perform these functions automatically as the machines
are being put into and out of operation and that by the employment of simple and
not intricate and complicated parts, is the object of this part of my invention.
In carrying my invention into effect I make use of the sliding block ƒ usually
employed and operated by the screw grotated by the band wheel through the
wheels km which are used in all cases in this class of machinery for shifting the
driving belt in both directions as is well understood, however I couple this sliding
block to a lever n (pivotted at n to the fixed bracket o) by means of a suitably
slotted rod or extension p so that when a certain part of the path of notion of this
block has been reached, as it moves from the position shown by fig. 4 where the
machine is at rest into that shown by fig. 7 where it has brought the belt from the
loose on to the fast pulley and has thus put the machine in motion, the rod
commence to transmit motion to its lever n the other art of which is thus moved
from beneath the end of the inclined lever r which is thus liberated and falls into
the position shown by broken lines fig. 6. The falling of this lover causes the
shaft a to which it is secured to oscillate so that its arms t move the sliding bars
to which they are coupled in the well known inanner for freeing the trap levers and
thus enabling them to assume their working positions.
will
Now as the block is being moved in the opposite direction that is from the
one in which it is shown by fig. 7 into that shown by fig. 4 as it approaches the
latter position its antifriction bowl u comes in contact with the inclined flange ou
the lever and raises it until its position shown by said fig. 6 is finally reached by
which means the parts for operating the trap-levers to place them in the positions
they have to occupy during the inaction of the machine, and during the last short
part of the motion of this sliding block being performed the rod p will have forced
or noved the lever n back into its position shown by fig. 4 in which it is beneath
the lover r where it will romain in order to retain said lever in its position shown
in full lines fig. 6 until the block f is again moved back uearly into the position
shown by fig. 7 in which the liberating of said lever r is carried out as herein-
before described.
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

page_text: same being constructed and arranged to operate in conjunction with the other parts
substantially as set forth.
