"IMPROVEMENTS IN SELF REGULATING REGISTERING AND INDICATING MECHANISM
APPLICABLE TO ALL KINDS OF MACHINERY WHERE LACE WOVEN AND OTHER
FABRICS ARE TAKEN OVER OR WOUND ON TO A BEAM OR ROLLER
"
Heretofore great difficulty has been experienced by manufacturers of lace woven
and other fabrics made on machinery where the work is taken over or wound on
to a beam or roller by reason of the uncertainty of the apparatus hitherto employed
for actuating the beam or roller at one uniform rate.
By the methods at present employed it is impossible to get the work exactly of
the same quality throughout and my invention is designed to meet this difficulty
and ensure exactness and uniformity in the quality of the fabric throughout at the
same time meeting the long felt want of measuring the yards or other quantities or.
lengths indicating the racks or whatever mode of measurement or custom of
measurement or indication the particular machine or machines (to which the
apparatus is applicable) may use.
For this purpose I will describe the application of my improved apparatus to a
twist lace machine as an example of one of the many machines making lace woven
and other fabrics where the work is taken or wound on to a beam or roller and to
which my invention is applicable.
In doing this I do not intend to limit the applicability of my invention to this
machine alone but simply to use it as one illustration of the various machines to
which my invention is applicable modifications as may be necessary being made in,
order to render the apparatus applicable to each particular machine
By my improved combination of apparatus and method of working the work is
regulated to exactness combined with the registration of the number of yards on:
the roller the apparatus also indicating the number of racks or whatever other
customary mode or modes of reckoning may be used for the particular machine to
which my invention is applicable.
Thus this improved apparatus combines the self regulation of the work the
number of yards or other lengths the number of racks the number of inches to the,
rack or whatever mode or modes of reckoning may be used.

page_text: Where the work in machines for making lace woven and other fabrics is taken
received or wound on to a beam or roller that beam or roller has hitherto been
driven round by some apparatus such apparatus having to be altered from time to
time as the beam or roller increases in diameter by reason of the work being wound
upon it.
When the beam or roller becomes larger in diameter by reason of the work being
wound upon it the apparatus for driving that beam or roller round has to be
altered so as to make the roller travel slower and thus compensate as will be seen.
in a very inadequate manner for the ever increasing circumference of the beam or
roller caused by the work being wound upon it.
The apparatus in use at the present time consists of a worm wheel fixed on the
end of the roller shaft the worm working in it on a shaft which has a wheel
attached with rack teeth cut in it. A clauker which works the rack wheel rises by
means of a cam or other mechanism and drops on to a set screw thus by lowering
or elevating the set screw the clauker takes either more or less of the rack wheel
teeth and thus the beam or roller is driven.
No regularity or exactness is ensured by this means as it is certain that if the
beam or roller is always increasing in its circumference the clauker working the
rack wheel must in proportion always be taking less teeth and this can only be
effected by means of self regulating mechanism the arrangement and combination of
which I will now describe;.
I employ two independent mechanical motions or movements for actuating
the different parts of the mechanism One part of the mechanism is actuated by
the work (whilst being wound upon the beam or roller) serving to drive a roller
wheel or other piece of mechanism equally applicable for serving the same purpose
such roller wheel or other mechanism being used for actuating a certain part of my
improved mechanism hereinafter described
The other driving mechanism is actuated by means of any of the revolving shafts
connected with the machines to which my invention may be applied. Or the
driving apparatus may be actuated by motive power derived from some other or
independent source as may be found most convenient.
I will first describe that part of my improved mechanism which is actuated by
the work roller or mechanism combined therewith then I will describe that part of
my improved mechanism which is actuated by other or independent mechanism and
lastly the application and relative value that one arrangement of my improved
mechanism bears to the other in affording a perfect check one upon the other and so
vice versa as the requirements in maintaining the same quality in the work
demands.
Upon the end of the shaft with the roller wheel or other mechanism attached
which is actuated by the work roller there is another wheel with 3 recesses cut in
it on both sides. This wheel is divided into 3 segments on each side each segment
being similarly formed in such manner as to allow of two small horizontal slides
governed by two springs one slide being forced forward by one spring while the
other is forced backward by the other spring both falling into such recesses and
rising to the surface gradually in such time as is hereinafter explained.
On the same shaft there is also a pinion which actuates a wheel and worm and
wheel such pinion wheels and worms being so calculated as to register the number
of yards or other quantities of work passing over the roller wheel or other
mechanism actuated by the work roller as previously described.
The other independent mechanism before referred to is actuated by any suitable
mechanical means for producing rotary motion calculated to drive a shaft once
round in 1920 motions of a Twist Lace Machine (which is called a "rack")
The several parts of my improved apparatus-which are actuated by the above
series of wheels worms cams or other mechanism are as follows.

I make use of the same means for actuating the beam or roller viz by the use
of the worm wheel on the roller shaft the worm that works in that wheel together
with the rack wheel and clauker with the cam or other apparatus raising that
.

page_text: clauker as previously described only instead of the clauker dropping on to a set-
screw I arrange a lever upon which the clauker drops this lever rests on the
regulating screw moved up and down by part of the apparatus which I will now
describe.
The regulating screw has a passage through it inside of which there is a tongue
or projection which acts in a groove cut in a round bar or rod this grooved rod fits
inside the tubular regulating screw-the screw working freely up and down with
the tongue in the groove
Near the bottom of this grooved rod or shaft a wheel is fixed with teeth cut in
it which fit in another wheel with corresponding teeth placed under it which works
freely on the grooved rod or shaft being supported by a suitable support so as to
keep it in gear with the wheel above. An extra wheel is fixed to the bottom
wheel referred to with 8 or more or less pins fixed in it. Both of the last two
mentioned wheels are fixed together and work freely together on the grooved
Bhaft.
Two horizontal claukers (one each side of the extra wheel with the 8 or other
number of pins in it) are then placed in such a position so that whichever clauker
happens to be in such clauker immediately engages with one of the pins and by
means of a lever forced up by means of an eccentric or other cam and drawn back
by means of spring power the two claukers are drawn down and whichever one is
in and not held out by the action set in motion by the first described actuating
mechanism that clauker secures one of the pins before referred to and the wheel
is drawn round and either elevates or lowers the regulating screw according to
which clauker happens to have engaged a pin.
The fall of the lever which actuates the claukers does not occur at each
revolution of of the cam. It is governed by an apparatus a description of which is
as follows.
The two claukers referred to are connected on to a T shaped slide the T slide
is then fixed on to the bottom of the lever before referred to the lever is connected
at the top to another slide and the slide is forced forward by means of a cam and
drawn back by a spring. The tail end of the T shaped slide is arrested and
governed in its movement by the end of a rod or stop which descends behind the
tail end of the T slide and thus prevents it from dropping by the pressure of the
spring referred to. This rod is connected to a lever at one end. At the other end
of this lever another rod is connected at the bottom of this rod a shoulder projects
out. Another right angled lever (the rise and fall of which is hereinafter
explained) is arranged one end of which rests on the shoulder referred to while
the other end rest upon a wheel or disc which revolves once in a "rack
(1920 motions of a Twist Lace Machine) in this disc recesses are cut the number
of which depends on the number of inches of work required to be made to the
rack so that the value of every recess in the disc is equal to an inch of work wound
on the beam or roller.
"
The end of the right angled lever which rests on the recess disc is shaped to fit
into such recesses and is forced into them as they come round by a spring fixed on.
the end of the lever corresponding to that end which fits into each recess.
By the arrangement of levers above described the rod which falls behind the
Tshaped slide is lifted once to every recess in the disc and thus allows the lever
which drives the two claukers connected to the T shaped slide to come into action
by the spring and is forced back to its position again by the cam.
It will be seen that when the rod is raised from behind the lever it has to remain,
up a sufficient time to allow for the stroke of the lever which actuates the T alide
and claukers and when such stroke has been taken to drop at once behind the
T slide
This action is effected by a slide passing into a recess in the rod which supports'
the T slide.
.
When the rod or stop is raised up from behind the end of the T slide by means
of the arrangement of levers governed by the recess disc this slide immediately
;

page_text: enters into a recess and holds the rod or stop up. Then directly the lever takes its
stroke another lever which is fixed to the slide acting on the cam referred to draws
the slide out of the rod or stop so that by the time the lever gets back to its
destination by means of the cam the rod or stop is free to drop behind the T slide
and thus hold it up until the next recess in the disc comes round.
By the foregoing means the two claukers connected to the T slide take a stroke
down and up once to each recess in the disc.
In order to regulate the time and fall of the lever to the time and fall of the cam
arrange another rod which drops into a recess in the slide actuated by the cam
and spring.
This rod is operated by means of a lever which is raised by a pin in the cam
placed in such a position that the lever is lifted and the rod raised out of the slide
just when the cam begins to fall on the surface. By this means the full stroke
given by the cam to the lever is effected otherwise when the rod supporting the
end of the T slide is drawn out the lever would be liable to fall upon the cam in
any position and therefore the full stroke to the lever actuating the T slide and
claukers would not be given.
Having described the action of the two claukers acting on each side of the pin
wheel falling and rising once to every recess in the disc each recess being equivalent
to an inch of work made I will now proceed to describe the connection between
and the relative value that that part of the apparatus actuated by the passing of
the work to the work roller has to the other part of the apparatus actuated by
apparatus independent thereof.
The two slides actuated by the cam referred to and set in motion by the
movement of the work come in contact with the two clankers actuated by the series
of rods slides and levers driven by the other independent driving apparatus.
Each slide when down holds each clauker that comes in contact with it away
from the pins on the wheel which moves the regulating screw up and down. The
cam wheel which actuates these slides is so arranged that the back clauker remains
in while the front clauker remains out and so vice versa so that if the recess disc
actuates the levers before an inch of work has been made and passed over the
roller and before the clauker is pushed away from the pin by means of the slides
actuated by the slide cam, the back clauker (not being held out) arrests one of the
pins and the screw is immediately lowered and thus the clauker actuating the work
beam or roller is allowed to drop lower and thus take more teeth of the rack wheel
which drives the work beam or roller round and thus the roller travels at an
increased speed consequently drawing or taking up the work quicker and the work
being the means of actuating the slide cam the latter travels at a greater speed and
if it has travelled fast enough so as to allow the back slide to fall into the recess
and so liberate the back clauker from the pins by the time the next recess comes
round to actuate the claukers (the front clauker being held out just at that
moment) both claukers miss the pins and the regulating screw remains stationary.
Therefore when the cam travels round in time with the recess disc it shows that
an inch of work has been made and passed over the roller. On the other hand
should the work be wound or racked up too quickly the recess in the cam wheel
actuating the front slide allows the slide to slip down and the front clauker is then
ready to take a pin by the time the recess in the disc does come round and
consequently elevates the screw to make the work roller travel slower.
There is a little time allowed between the rise and fall of each slide to each
clauker so that if the lever acts within that time the claukers miss the pins and
the regulating screw remains stationary.
Mechanism is applied for setting the regulating screw at any desired elevation
according to what number of inches is required to be made to the "rack."
An indicating dial with a pointer is arranged in combination with the regulating
screw and as the screw is lowered or raised so the pointer rises or falls to the
figures on the dial.

page_text: In starting to make a piece of work whatever number of inches is required to be
made to the "rack" the regulating screw is lowered or elevated until the pointer
points to the corresponding number to such number of inches to the rack required.
Mechanism is also applied for registering and indicating the number of yards
and racks.
The mechanism employed for registering the number of yards consists of an
arrangement of pinions wheels and worms driven by the shaft which works the
mechanism of the slides that govern the two claukers such shaft being set in
motion by the work passing over a small roller placed between the facing bar and
the beam or roller which the work is taken over or wound upon.
The mechanism employed for indicating the number of of racks consists of an
arrangement of pinions wheels and worms actuated by the shaft on which the
recess disc is mounted this shaft revolving once round to each rack.
Mechanism is applied for throwing the apparatus out of gear with the particular
machine to which it may be applied.
A stopping lever is also arranged to prevent the roller (actuating the slides to
the claukers) from moving when the work is not resting upon it.
Having described my invention as applied to a lace machine it will be evident
to a competent mechanic that the self regulating apparatus previously described
may be considerably varied in its construction and arrangement without departing
from the true character of my invention in order to obtain equality and uniformity
in the work produced which is the essential object of my invention whatever
modification of self regulating apparatus or mechanism of this character may be
employed to effect this object.
From the foregoing description apparatus of the character previously described
may be readily applied (by a mechanic acquainted with this class of machinery) to
other machines where the work is taken over and wound on to a beam or roller.
When the regulating apparatus is put out of gear the regulating screw can be
adjusted by the workman by hand and used as the ordinary set screw is used for
regulating the rise and fall of the clauker as at present.
