Leeds, in the County of York, Machine Maker, for an Invention of
IMPROVEMENTS IN APPARATUS EMPLOYED IN PREPARING, SIZING, DRYING,
PROVISIONAL SPECIFICATION left by the said William Bywater at the
Office of the Commissioners of Patents on the 2nd June 1880.
WILLIAM BYWATER, of Sweet Street Foundry, Holbeck, Leeds, in the County of
York, Machine Maker. "IMPROVEMENTS IN APPARATUS EMPLOYED IN PREPARING,
SIZING, DRYING, AND WARPING WOOLLEN, WORSTED, AND OTHER YARNS."
In the use of apparatus employed in preparing, sizing, drying, and warping
woollen, worsted, and other yarns, the regulation of the length of yarn for the
time to be operated upon is dependent upon the attention of the attendant
watching the movement of an indicator, so as to stop the motions of the machine
when the indicator indicates that the length desired has been operated upon,
consequently, by absence or inattention of the attendant at the time required,
irregularity and loss are sustained.
The object of the Invention is to remedy these evils by causing the operations
of stopping the_motions of the apparatus, at the times desired, to be effected
automatically. For this purpose I employ a screw motion to act upon and carry
forward a tappet, which, when it arrives at the point corresponding with the length
at which it is desired the apparatus should stop, acts on a lever or such like motion
to stop the further motions of the machine.
The setting of the motion for operating on the length desired is effected by the
attendant, aided by an index affecting a connection with the screw and tappet at
the position desired.
The roll or "cheese" of yarn is, according to present practice, wound by contact
of the surface of the roll of yarn with the surface of a pulley to which positive
motion is given, but owing to the small extent of surface of this pulley in contact
with the yarn at any one time, a slipping of the yarn often takes place, and
irregular measurement results. To remedy this evil I employ a pair of pulleys
carrying a belt or apron; these pulleys with the belt or apron are applied to act on
an extended surface of the roll or "cheese" of yarn, thus securing more positive
action.

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent filed
by the said William Bywater in the Great Seal Patent Office on the
30th November 1880.
WILLIAM BYWATER, of Sweet Street Foundry, Holbeck, Leeds, in the County of
York, Machine Maker. "IMPROVEMENTS IN APPARATUS EMPLOYED IN PREPARING,
SIZING, DRYING, AND WARPING WOOLLEN, WORSTED, AND OTHER YARNS."
In the use of apparatus employed in preparing, sizing, drying, and warping
woollen, worsted and other yarns, the regulation of the length of yarn for
the time to be operated upon is dependent upon the attention of the attendant
watching the movement of an indicator, so as to stop the motions of the machine
when the indicator indicates that the length desired has been operated upon,
consequently, by absence or inattention of the attendant at the time required,
irregularity and loss are sustained.
The object of the first part of my Invention is to remedy these evils by causing
the operations of stopping the motions of the apparatus, at the times desired, to
be effected automatically. For this purpose I employ a screw motion to act upon
and carry forward a tappet, which, when it arrives at the point corresponding with
the length at which it is desired the apparatus should stop, acts on a lever or such
like motion to stop the further motions of the machine.
The setting of the motion for operating on the length desired is effected by the
attendant, aided by an index effecting a connection with the screw and tappet at
the position desired.
The roll or "cheese" of yarn is, according to present practice, wound by contact
of the surface of the roll of yarn with the surface of a pulley, to which positive
motion is given, but owing to the small extent of surface of this pulley in contact
with the yarn at any one time, a slipping of the yarn often takes place, and
irregular measurement results. To remedy this evil I, according to the second part
of my Invention, employ a pair of pulleys carrying belt or apron; these pulleys
with the belt or apron are applied to act on an extended surface of the roll or
"cheese" of yarn, thus securing more positive action.
But that the Invention may be the better understood, I will, by the aid of the
accompanying Drawings, proceed to describe means pursued by me in carrying the
same into effect.
DESCRIPTION OF THE DRAWINGS.
Figure 1 shows a side view, Figure 2 a section of parts, Figure 3 a plan view,
and Figure 4 details on a larger scale of apparatus with improvements applied
thereto, according to the first part of my Invention. In each of the views the
same letters are employed to indicate corresponding parts. a, a, represents the
main framing; b, the indicator; c is the screw motion, which acts upon and carries
forward the tappet d, which when it in its motion arrives at the point for the time
desired acts on the upper end of the lever e, which then by its connection with
one end of the elbow lever f, the other end of which is connected to the rod g' of
the belt fork g, operates to stop the further motion of the machine. The screw c
is made to revolve by being geared to the cheese A with bevil and spur wheels, as
shewn in the Drawing. The tappet d is made to traverse on the screw c by means
of a tongue h, which is pressed into the thread of the screw c by means of a small
spring h. The tongue h is released from the screw c by pulling the small
handle h².
The setting of the motions for operating on the length desired by the attendant
is effected in the following manner :-In making the first "cheese" of a warp the
tappet d is brought to the end c¹ of the screw c, the tongue h is then set in the

page_text: thread of the screw c. After the required length has been wound upon the cheese A
the tappet d will have traversed up the screw c and the index b, say, to mark
150, reckoning from 6¹ of index b; then in order to make the next and all the
following cheeses of the same warp the tappet d must be set in the screw c at mark
150, reckoning from 62 of index 6; the tappet d will then in its traverse come in
contact with the upper end of the lever e, and will move it to operate the fork g,
when, say, 150 has been traversed. The end of the screw c marked c² is cut to a
coarser thread in order to accelerate the motion of the tappet d when about to
operate upon the lever e. By these means a more certain and quicker stop is
given to the machine.
I will now proceed to describe the second part of my Invention. A represents
a roll or "cheese" of yarn in the course of being wound; B is the belt or apron,
which is supported and operated by the pair of pulleys C, C, for the purpose of
giving the desired surface motion to the roll or cheese," and by which a greatly
extended moving surface for that purpose is obtained and a more positive action.
Having thus described my Invention, and means which I adopt in carrying the
same into effect, I would have it understood that what I claim as the improvements
in apparatus employed in preparing, sizing, drying, and warping woollen, worsted,
and other yarns is,―
Firstly. The arranging or combining parts whereby the length of yarn for the
time to be wound may be definitely and automatically determined, substantially
as described, and
Secondly. I claim the arranging or combining parts whereby a belt or apron
supported by a pair of pulleys is employed to give surface motion to the roll or
cheese," substantially as described.
In witness whereof, I, the said William Bywater, have hereunto set my
hand and seal, this Twenty seventh day of November, One thousand eight
hundred and eighty.
WILLIAM BYWATER. (L.S.)
