We HENRY WALTERS Managing Director of and on behalf of David Bowlas
Limited, of the Victoria Mills, Redditch in the County of Lancaster, Cotton
Spinners, Doublers and Machinists, and JOHN SAXON of Redditch Green in the
County of Lancaster, Machine Fitter do hereby declare the nature of our
Invention for IMPROVEMENTS IN SELF ACTING HEALD KNITTING MACHINES FOR
TOKENING OR INDICATING OR REGISTERING THE COUNTS IN HEALDS OR HARNESS
FOR LOOMS, to be as follows:-
Two or more healds or harness corresponding with the number of dents in the
reed used therewith are employed in looms for alternately lifting the warp threads
to form the succession of sheds for the passage of the shuttle which as it passes
through from side to side lays in the weft. Hitherto every twentieth transverse
thread of the harness has been tokened or indicated by a counting thread inserted
in the edge of the harness by the action of the machine. This system causes much
waste of time and with a view to simplify it, we have devised the present
improvements which instead of tokening by count or number of threads indicate
by the inch, or two inches, or other fixed length so that a reed of harness containing
any stated number of threads in such fixed length is readily estimated by the
number of inches or lengths that it measures, each inch, or two inches or other
fixed length being indicated by a colored thread that is taken up and looped into
one edge of the heald or harness by the action of the parts we add to the machine,
at the termination of each successive inch or two inches or any other fixed length
that may be preferred.
According to the old system of counts by twenties, a different token or count
wheel is required for every fresh reed of healds or harness; (for example) a 50 reed
heald or harness, requires a 50 token or count wheel, and so on for other numbers,
but by our improved mode of tokening an indicating wheel with 70 teeth is
employed for all counts, no matter what number of threads the reed of healds or
harness may contain, and this so simplifies the process that a saving of much time
and expense to the manufacturer results therefrom.

page_text: The parts we employ to effect our improvements comprise an indicating or
tokening wheel that carries the finger which at a certain point in every revolution
strikes the trigger that causes the introduction of the tokening thread. This wheel
has 70 teeth which engage with a pinion of 14 teeth. The pinion is mounted to
revolve freely on a fixed stud or centre which also carries à spur bevel wheel that
is made fast to the pinion. The bevel wheel has 36 teeth which engage with or
receive motion from a smaller bevel wheel with 18 teeth.. The shaft that carries
the last named bevel wheel is made to revolve at the same speed as the machine
screw by means of three mitre wheels of uniform size and fixed respectively, one
on the other end of the said shaft, another which faces the first, is fixed on the end
of what is called the count or change wheel shaft, and an intermediate mitre wheel
that is in gear with both the others and pairs with them, is fixed on the end of
the machine screw. The power of force which actuates the 70 teeth indicating
wheel comes through the count or change wheel shaft, and as it passes through the
three mitre wheels, it at the same time actuates the screw. The screw carries
5 threads to the inch and therefore in order to move the harness or work in process
a fixed length of two inches it makes 10 revolutions whilst the 70 teeth tokening
wheel revolves only once.
When it is desired to change the fixed indicated length to one inch, it is easily
effected by substituting a pair of mitre wheels in the places of the before mentioned
two bevel wheels of 36 and 18 teeth respectively. The screw will then only make
5 turns whilst the 70 teeth tokening wheel revolves once, and the colored thread
will be inserted at the end of every successive inch, so that it will be seen that the
tokening or indicating thread is looped into the edge of the heald or harness every
time the 70 teeth tokening or indicating wheel completes a revolution.
The number or count of threads in a fixed length is regulated by change wheels
connected with the outer end of the change wheel shaft, but as this part of the
machine forms no part of our Invention further than the fact that we obtain
motion from the said shaft a description thereof is unnecessary.

page_text: We HENRY WALTERS, Managing Director of and on behalf of David Bowlas,
Limited of the Victoria Mills Reddish in the County of Lancaster, Cotton Spinners,
Doublers and Machinists, and JOHN SAXON of Reddish Green in the County of
Lancaster, Machine Fitter, do hereby declare the nature of our Invention for
IMPROVEMENTS IN SELF ACTING HEALD KNITTING MACHINES FOR TOKENING OR
INDICATING AND REGISTERING THE COUNTS IN HEALDS OR HARNESS FOR
LOOMS and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
Our Invention relating to improved tokening apparatus, is applied as an
accessory to heald knitting machines for the purpose of introducing the indicating
thread in one edge of the harness at regular measured intervals. Two or more
healds or harness the number of eyes whereof collectively correspond with the
number of dents in the reed used therewith, are employed to act alternately when
two healds are used, or otherwise when three or more are required in looms for
lifting and guiding the warp threads to form the succession of sheds for the passage
of the shuttle, which as it passes through from side to side, lays in the weft.
According to the ordinary system of tokening which has prevailed of late years,
every twentieth transverse thread or eye of the harness has been tokened or
indicated by a counting thread of different colour inserted in one edge of the
harness by the action of the machine-This system causes much waste of time,
and with a view to simplify it and save time, we have devised the present
improvements which instead of tokening by count or number of threads, the
tokening is by our apparatus made to indicate by the inch or two inches or other
fixed length, so that a reed of harness containing any stated number of threads in
such fixed length is readily estimated by the number of inches or lengths that it
measures, each inch or two inches or other fixed length being indicated by a
coloured thread that is taken up and looped into one edge of the heald or harness
by the action of the parts we add to the machine at the termination of each
successive inch or two inches, or any other fixed length that may be preferred.
According to the old system of counts by measure, a different token or count
wheel was required for every fresh reed of healds or harness-for example, a
50 reed heald or harness required a 50 token or count wheel, that is, a wheel
with 50 teeth was required and so on for other numbers, but by our improved
mode of tokening, an indicating wheel with any number of teeth divisible by 5,
preferably with 70 teeth is employed for all counts, no matter what number of
threads the reed of healds or harness may contain, and this so simplifies the process
that a saving of much time and consequent expense, and the avoidance of mistakes
results therefrom.
The parts we employ to effect our improvements are shewn in combination by
the figure on the Drawing hereto annexed. They comprise an indicating or
tokening wheel marked G that carries the adjustable finger I, which at a certain
point in every revolution of the wheel, strikes the trigger J, that causes the
insertion of the tokening thread O by depressing the thread rod K. The wheel G
has 70 teeth which engage with H, that marks a pinion with 14 teeth. This
pinion is mounted to revolve freely on a fixed stud or centre which also carries E, that
indicates a spur bevel wheel, which is made fast to the pinion H. The bevel wheel
E has 36 teeth which engage with and obtain motion from F that marks a smaller
bevel wheel with 18 teeth. The shaft F¹ that carries the last named bevel wheel F
is made to revolve at the same speed as the machine screw M, by means of three

page_text: mitre wheels marked respectively B. C. and D. These wheels severally are fixed
one (D) on the inner end of the shaft F', another (B) which faces the first, is fixed
on the end of what is called the count or change wheel shaft (B¹) and the third
marked C, is an intermediate mitre wheel that engages with both of the others
(D and B) and pairs with them, is fixed on the end of the machine screw M.
The screw carries 5 threads to the inch, and therefore in order to move the harness
or work in process (N) a fixed length of two inches, it will, according to the
arrangement shown on the Drawing annexed and herein described make 10
revolutions whilst the 70 teeth tokening wheel G revolves only once.
When it is desired to change the fixed indicated length, say to one inch, it is
easily effected by substituting a pair of mitre wheels in the places of the before
mentioned two bevel wheels E and F of 36 and 18 teeth respectively. The
screw M will then only make 5 turns whilst the 70 teeth tokening wheel G,
revolves once, and the coloured thread O, will be inserted in the edge of the
heald N at the end of every successive inch, so it will be seen that the tokening
or indicating thread O, is looped into the edge of the heald or harness every time
the tokening wheel G completes a revolution. A indicates a portion of the iron
frame of the heald knitting machine, and L marks the bobbin from which the
colored tokening thread O is drawn.
The number of count of threads in a fixed length is regulated in the usual way
by means of change wheels mounted on an adjustable center, so that any change
wheel the required size for making either fine counts or coarse counts, can readily
be placed in gear with the tooth wheel P, that is fixed on the outer end of the
change wheel shaft B. But this part of the heald machine forms no part of our
Invention which commences as seen on the Drawing with the mitre wheel D for
actuating which and imparting motion to the several parts of our tokening
apparatus, we obtain motion from the shaft B' through the aid of the two mitre
wheels C and B, which are common to most machines.
Having now described and ascertained the nature of our Invention, its object,
use, and mode of operating, we wish it understood that we do,, not confine
ourselves to any precise arrangements of the several parts so long as they are kept
in combination, and therefore what we claim as our Invention and believe to be
new consists in as follows, that is to say :-
First. We claim by means of such an apparatus as we have described, inserting
in the edge of healds or harness whilst being manufactured in self acting heald
knitting machines, a coloured thread to indicate or token by lineal incasure, instead
of by counts or twenties.
Second. We claim in heald knitting machines, the use of one wheel having any
convenient number of teeth divisible by 5 for the purpose of tokening all counts
or all special fixed lengths on the edge of healds or harness, in the manner and for
the purposes herein described.
Third. We claim the giving motion to our tokening apparatus by motive force
received through the change wheel of the heald knitting machine and passed
through the mitre wheel C that is fixed on the end of the heald knitting machine
screw, after the manner and for the purposes herein described.
