I, ARCHIBALD RUSSELL MILLER, at Cambuslang Dyeworks, near Glasgow,
Lanarkshire, Turkey Red Dyer, do hereby declare the nature of my invention
to be as follows:-
This invention has reference to and comprises a new or improved method, and
arrangement and combination of devices or appliances, for guiding yarn and thread
from bobbins or hanks to the usual testing machines, and which will enable the
measuring or testing operations to proceed continuously and with one yarn or
thread guide, instead of employing a series of these guides and requiring inter-
mittent periodic stoppages of the machine for each length being tested as has
heretofore been the case.
By my improvements I take one of the usual scroll glass or other guides into or
through the eye of which each yarn or thread to be measured or tested in lengths
is passed, and I mount this guide on the upper end of a vertical stem, having its
lower end screwed into a sliding block. This sliding block is fitted to travel within
a hollow or tubular longitudinal frame, preferably mounted at one side of the
testing machine, and the block is moved or actuated through a connecting cord by
a gravitation acting hanging weight, and the movements of the block are
controlled by a series of hand operated levers. The block with guide is held in
position while a length of yarn or thread is being tested, by one of these hand
operated levers, the moving or releasing of which will liberate the block to be
drawn on by its connecting cord and weight until it is held by the next lever in
succession where a new length of yarn or thread would be passed through the
guide, and so on for as many different lengths as may be desired to be tested;
while the block with guide can be moved back to its original starting or any inter-
mediate position on its frame, and any or all of the operations be performed without
stopping the yarn or thread testing machines.
In carrying these improvements into practice under one arrangement I make the
longitudinal guide frame for the sliding block in the form of a hollow tube or case
of square or rectangular shape in transverse section with longitudinal slots or
openings along the greater part of its two sides. A transverse bar or pin would
be screwed through the lower part of the sliding block the ends of which would
project out horizontally on each side of it and pass through the longitudinal slots
to guide the block in its sliding movements. While the top of frame would be
formed with a longitudinal slit or be left open for the vertical stem of guide
attached to sliding block to pass through. A cord or line would have its one end
attached to an eye or hook on the front of sliding block, and pass over a grooved
guide pulley at the end of frame, and be attached at its other end to a hanging
weight to operate or pull the sliding block. A sliding sole would be mounted on
the under surface of sliding block to slide on the lower inner surface of tubular
frame and have one of its longitudinal edges formed of an angled or curved shape.
A series of hand operated or trigger vertical oscillating levers as say three would
be fulcrumed at distances apart, near their upper end, each on a central pin
mounted in under hung brackets, attached to the bottom of frame, and having the
top ends of levers projecting through transverse slots in bottom of frame; and part
of the top end of these levers would be formed of a reverse angled or curved shape
to that of the sole of sliding block.
The operatious of these guide devices are as follows -When lengths of yarn or
threads are to be tested, as say each 120 yards, the thread would be passed from

page_text: the bobbin or hank through the glass guide to the testing machine. The sliding
block carrying the guide would be held by the top of the first trigger lever
abutting or acting against the sole of slide block, but when the required length
had all passed through the guide, the lever would be oscillated by hand, and the
slide block would be automatically pulled by the hanging weight, until it came in
contact and was held by the next lever of the series, while the former lever would by
gravity swing back to its perpendicular acting position. The second length of yarn
or thread would now be tested in the new position of guide without stopping the
testing machine, and after it had all passed through, the second lever would be
oscillated and the slide block automatically move on to be stopped by the third
lever, where the same operations would go on as at the first and second levers,
and after being released from this third lever the slide block would preferably
move on to the end of the race or longitudinal slots where a fourth length of yarn
or thread may be guided through the glass eye. The slide block can then be
brought back to its original starting position on the frame to resume a corresponding
series of operations, and in bringing it back the angled or inclined side of sole will
come in contact with the correspondingly shaped reverse edge of the trigger levers,
and move there to the one side, so that the block may pass them, and these levers
will automatically fall into their perpendicular acting position after the sliding
block has passed. A removable metal plug would be secured by screws at the one
end of tubular frame for enabling sliding block and guide to be removed for
renewal or repair. Instead of oscillating hanging trigger levers being used, spring
acting levers may be adopted although these latter are not preferred. And instead
of the block sliding on plane surfaces it may have its sole formed of a section to
run on travelling balls or rollers so as to minimise friction, or it may be mounted on
travelling wheels or rollers.

Improvements in and relating to the Guiding of Yarn and Thread
to Testing Machines.
I, ARCHIBALD RUSSELL MILLER, at Cambuslang Dyeworks, near Glasgow,
Lanarkshire, Turkey Red Dyer, do hereby declare the nature of my invention, and
in what manner the same is to be performed to be particularly described and
ascertained in and by the following statement in writing, that is to say :-
.
This invention has reference to and comprises a new or improved method and
arrangement and combination of device or appliances for guiding yarn and thread
from bobbins or hanks to the usual length testing machines, and which will enable
the measuring or testing operations to proceed continuously and with one yarn or
thread guide, instead of employing a series of these guides and requiring inter-
mittent and periodic stoppages of the machine for each length being tested as has
heretofore been the case.
And in order that my said invention and the manner of performing or carrying
the same into effect or practice may be properly understood, I have hereunto
appended an explanatory sheet of drawings in which the same reference letters are
used to indicate corresponding parts in all the figures where shown.
Figure 1 is a side sectional elevation and Figure 2 a corresponding plan showing
an arrangement of my improved devices or appliances for guiding yarn and thread
to length testing machines.
Figure 3 is a transverse section taken on the line 1-1 Figure 1, and
Figure 4 shows detached diagram views of the acting surfaces of the thread guide
slide, and one of the trigger levers, the arrows indicating the backward direction of
motion of the former.

page_text: Referring to these drawings:-By my improvements I take one of the usual
scroll glass or other guides a into or through the eye a', of which each yarn or
thread to be measured or tested in lengths is passed, and I mount this guide on the
upper end of a vertical stem a2 having its lower end screwed into a sliding block b.
This sliding block is fitted to travel within a hollow or tubular longitudinal
frame A preferably mounted at one side of the testing machine, and the block b is
moved or actuated through a connecting corde attached to it at 2 the other end of
cord having connected to it a gravitation acting hanging weight c', and the move-
ments of the block are controlled by a series of hand operated levers B. The
block with guide a is held in position while a length of yarn or thread is being
tested, by one of these hand operated levers B, the moving or releasing of which
will liberate the block to be drawn on by its connecting cord c and weight c¹ until
it is held by the next lever B in succession where a new length of yarn or thread
would be drawn through the hole a' in the guide a and so on for as many different
lengths as may be desired to be tested; while the block with guide can be moved
back to its original starting or any intermediate position in its frame A, and any or
all of the operations be performed without stopping the yarn or thread testing
machines.
C
In carrying these improvements into practice under one arrangement, as shown
in these drawings, I make the longitudinal guide frame for the sliding block b in
the form of a hollow tube or case A preferably of square or rectangular shape in
transverse section but it might be of cylindrical or other shape with longitudinal
slots or openings A' along the greater part of its two sides. A transverse bar or
pin is screwed through the lower part of the sliding block b, the ends of which
would project out horizontally on each side of it and pass through the longitudinal
slots A to guide the block b in its sliding movements. While the top of frame
would be formed with a longitudinal slit or be left open at A for the vertical
stem a² of guide attached to sliding block to pass through. A cord or line chas
its one end attached to an eye or hook at c² on the front of sliding block, and passes
over a grooved guide pulley 11 at the end of frame A and is attached at its other
end to a hanging weight e' to operate or pull the sliding block b. A sliding sole b²
is formed or mounted on the under surface of the sliding block b, to slide on the
lower inner surface A2 of the tubular frame A and has one of its longitudinal
edges 6 formed of an angled or curved shape, as shown particularly in Figure 4.
A series of hand operated or trigger vertical oscillating levers B, as say three are
fulcrumed at distances apart, near their upper end, each on a central pin B',
mounted in under-hung brackets B attached to the bottom A² of frame A, and
the top ends B2 of these levers B project through transverse slots A³ in bottom A³
of frame A; and part of the top end B2 of these levers B is formed at B, as shown
particularly in Figure 4 of a reverse angled or curved shape to that of the sole *
of the sliding block b.
The operations of these guide devices are as follows:-When lengths of yarn or
thread are to be tested, as say each 120 yards, the thread would be passed from the
bobbin or bank through the glass guides a, a', to the testing machine. The sliding
block 6 carrying the guide would be held by the top B2 of the first trigger lever B
abutting or acting against the sole of slide bleck b, but when the required length
had all passed through the guide a, a¹, the lever B would be oscillated by hand, and
the slide block b, would be automatically pulled by the cord c and hanging weight c¹,
until it came in contact and was held by the next lever B of the series, while the
former lever B would by gravity swing back to its perpendicular acting position.
The second length of yarn or thread would now be tested in the new position of
guide a, a', without stopping the testing machine, and after it had all passed
through, the second lever B, would be oscillated and the slide block b automatically
move on to be stopped by the third lever B, where the same operations would go
on as at the first and second levers, and after being released from this third lever
the slide block would preferably move on to the end of the race or longitudinal
slots A', where a fourth length of yarn or thread may be guided through the glass

page_text: eye a. The slide block b can then be brought back to its original starting position
on the frame A to perform a corresponding series of operations, and in bringing it
back, as indicated by the arrows in Figure 4 the angled or inclined side of sole b
will come in contact with the correspondingly shaped reverse diagonal edge B of
the top B2 of the trigger levers B, preferably slightly convex curved on its face,
and move these to the one side, so that the block b, may pass them, and these
levers B will automatically fall into their perpendicular acting position after the
sliding block has passed. A removable metal plug A* is secured by screws at the
one end of tubular frame A for enabling sliding block b, and guide a to be removed
for renewal or repair. Instead of oscillating hanging trigger levers being used,
spring acting levers or other movable catches or stops may be adopted and be
operated by hand or automatically. And instead of the block 6 sliding on plane
surfaces it may have its sole formed of a section to run on travelling balls or
rollers, so as to minimise friction or it may be mounted on travelling wheels or
rollers, and instead of being moved by a weight the block b may alternatively be
operated by an equivalent acting spring or springs.
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
I claim is-
First. The method of guiding yarn or thread to length testing machines by ene
movable guiding organ, in a continuous manner without requiring to intermittently
stop these testing machines, substantially as set forth.
Second. In a method of guiding yarn or thread to length testing machines the
arrangement and use of a single travelling guide within a frame or housing and
acting in combination with a series of levers, catches, or stops, substantially as and
for the purposes herein described, in reference to and by way of application shown
in the accompanying drawings.
Third. In a method of guiding yarn or thread to length testing machines, in
which a thread guide and levers or stops are used, the forming of the sole of guide,
and the top of the levers of a reverse angled or curved construction on one of
their adjacent edges so as to pass each other in the backward travel of guide,
substantially as herein described in reference to and shown in the accompanying
drawings.
