PROVISIONAL SPECIFICATION.
A New or Improved Device for Attachment to Thread Reels and
the like for Knotting and Cutting the Thread.
I, SAMUEL HENRY CROCKER of 172, Fleet Street, London, Engineer, do
hereby declare the nature of this invention to be as follows:-
This inveution relates to a device to be attached to thread reels and the like, by
means of which the thread can be cut and knotted at the same operation.
To form the knot the thread is passed over and around the instrument, which is
inserted in the end of the reel, and pulled, operating the parts hereinafter described,
causing a loop knot to be formed around a hook which cuts the thread at the centre
of the loop.
When an ordinary loop knot is formed on a thread and cut, the thread is
separated into two parts, one of which has a knot through which the end of the
other passes. On pulling the two apart, the latter will be pulled clear, leaving the
former with the knot. This is what occurs when the thread in the knotting device
is pulled, the hook cutting it in the middle of the loop, and the end of the part
remaining on the reel slipping through the knot formed on the detached part.
In order that this invention may be more clearly understood, reference is had to
the accompanying sheet of drawings, in which
Fig. 1 is a front and Fig. 2 a rear elevation of the knotter and reel, Fig. 3 is a
plan of the same,
Figs. 4 to 7 are views showing the formation of the loop in the thread,
Figs. 8 to 11 are detail views of parts of the device shown separate, and
Figs. 12 and 13 are respectively a front and rear elevation of a slightly modified
device.
The shank of the device is pushed into the centre hole of the reel A, the main
part resting on the end or face of the latter. The shank B is formed from a strip
of metal such as steel, bent over so as to form a spring, as shown more clearly
in Figs. 8 and 9, which, when pushed into the hole of the reel, will press against
the sides, and cause the device to be held firmly in place. The head or base plate C.
is formed in one with the shank and consists of a vertical part extending laterally
to the side of the reel, with a horizontal part c at top, having a slit c at the edge
or corner, the part e joining on to the main part at one end only. To this head is
pivotted a vertical plate D carrying a horizontal hook E at top, around which the
loop knot is formed. The plate is furnished with a nose dat its front end, and
according to one arrangement with a shoulder at the rear, for the purpose
hereinafter described. A spring F bears upon or is attached to the plate D, and
presses it upwards so that the hook E bears against the plate c. This spring E,
according to one arrangement as shown in Fig. 2, forms a pivot for the plate D,
serving to attach it to the plate C. The head C is bent round in front at C¹ the
upper edge of which part slopes downwards slightly, for the purposes hereinafter
described. A part at the bottom projects outwardly for the purpose of guiding
or leading the thread, and a small hook or projection c³ is also stamped from the
front c¹ of the head for that purpose. According to Figs. 12 and 13 the spring F
is furnished with a shoulder which takes the place of the shoulder d¹, the end of
the spring passing through a small loop on the back of the plate D, which
projects through a small slot in the head, allowing the spring when pushed
downward or forward to pull down the plate and hook, the end of the spring
sliding through the loop d'.

page_text: The method in which the knot is formed is as follows:-The thread G is passed
over the front C₁ of the head C, the projection preventing it slipping, and
allowing it to be placed in proper position when the device is placed in either end
of the reel. The thread is passed in front of the nose d thence over the back of
the head C, and back around the shoulder d' or f, under the hook and straight
past the top of the head. On pulling the thread from this end, it will pull forward
the shoulder and lower the plate D, with nose d. On the latter being lowered
sufficiently, the thread will slip along the slit cand the hook also being pulled
down, the part g' of the thread nearer to the reel will slip over the hook, the
sloping edge of the part c' ensuring this, while the end of the loop g³, formed as
above described, will at the same time slip over the shoulder d' or f, thence over
the projecting part c which guides it on to the hook. On the shoulder being
released the plate D and hook E will spring up into their former position, and the
pull on the thread continuing, a loop knot will be formed around the hook, as
shown in Figs. 4 to 7, the part g' of thread being caught by the hook on its return,
caused by the continued pull on the thread. The inner edge of the hook then cuts
the loop 9', separating the thread into two parts, the one detached from the reel,
having a knot formed at its end when the plain end of the other part is pulled
through.

A New or Improved Device for Attachment to Thread Reels and
the like for Knotting and Cutting the Thread.
I, SAMUEL HENRY CROCKER of 172 Fleet Street, London, Engineer, do
hereby declare the nature of this invention and in what manner the same is to
be performed, to be particularly described and ascertained in and by the following
statement:-
This invention relates to a device to be attached to thread reels and the like, by
means of which the thread can be cut and knotted at the same operation.
To form the knot the thread is passed over and around the instrument, which is
inserted in the end of the reel, and pulled, operating the parts hereinafter described,.
causing a loop knot to be formed around a hook which cuts the thread at the centre
of the loop.
When an ordinary loop knot is formed on a thread and cut, the thread is
separated into two parts, one of which has a knot through which the end of the
other passes.
On pulling the two apart, the latter will be pulled clear, leaving the
former with the knot. This is what occurs when the thread in the knotting device
is pulled, the hook cutting it in the middle of the loop, and the end of the part.
remaining on the reel slipping through the knot formed on the detached part.
In order that this invention may be more clearly understood, reference is had to
the drawings accompanying the Provisional Specification, in which
Fig. 1 is a front and Fig. 2 a rear elevation of the knotter and reel, Fig. 3 is
a plan of the same,
Figs. 4 to 7 are views showing the formation of the loop in the thread,
Figs. 8 to 1 are detail views of parts of the device shown separate, and
Figs. 12 and 13 are respectively à front and rear elevation of a slightly modified
device.
The shank of the device is pushed into the centre hole of the reel A, the main
part resting on the end or face of the latter. The shank B is formed from a strip
of metal such as steel, bent over so as to form a spring, as shown more clearly in

page_text: Figs. 8 and 9, which when pushed into the hole of the reel will press against the
sides, and cause the device to be held firmly in place. The head or base plate C is
formed in one with the shank and consists of a vertical part extending laterally to
the side of the reel, with a horizontal part c at top, having a slit c¹at the edge or
corner, the part c joining on to the main part at one end only. To this head is
pivotted a vertical plate D, carrying a horizontal hook E at top, around which
the loop knot is formed. The plate is furnished with a nose d at its front end, and
according to one arrangement with a shoulder d' at the rear, for the purpose herein-
after described. A spring F bears upon or is attached to the plate D, and presses
it upwards so that the hook E bears against the plate c. This spring E, according
to one arrangement as shown in Fig. 2, forms a pivot for the plate D, serving to
attach it to the plate C. The head C is bent round in front at C¹ the upper edge of
which part slopes downwards slightly, for the purposes hereinafter described. A
part 2 at the bottom projects outwardly for the purpose of guiding or leading the
thread, and a small hook or projection c* is also stamped from the front c' of the
head for that purpose. According to Figs. 12 and 13, the spring F is furnished
with a shoulder which takes the place of the shoulder d', the end of the spring
passing through a small loop d' on the back of the plate D which projects through
a small slot in the head, allowing the spring when pushed downward or forward
to pull down the plate and hook, the end of the spring sliding through the
loop d².
The method in which the knot is formed is as follows:-The thread G is passed
over the front C₁ of the head C, the projection C³ preventing it slipping, and
allowing it to be placed in proper position when the device is placed in either end
of the reel. The thread is passed in front of the nose d thence over the back of
the head C, and back around the shoulder d¹ or f, under the hook and straight past
the top of the head. On pulling the thread from this end, it will pull forward the
shoulder and lower the plate D, with nose d. On the latter being lowered
sufficiently, the thread g will slip along the slit c¹ and the hook also being pulled
down, the part gl of the thread nearer to the reel will slip over the hook, the
sloping edge of the part c' ensuring this, while the end of the loop 9' formed as
above described, will at the same time slip over the shoulder d' or thence over
the projecting part c which guides it on to the hook. On the shoulder being
released the plate D and hook E will spring up into their former position, and the
pull on the thread continuing, a loop knot will be formed around the hook, as shown
in Figs. 4 to 7, the part g¹ of the thread being caught by the hook on its return,
caused by the continued pull on the thread. The inner edge of the hook then cuts
the loop separating the thread into two parts, the one detached from the reel,
having a knot formed at its end when the plain end of the other part is pulled
through.
Having now particularly described and ascertained the nature of my inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
(1) In a thread knotting and cutting device, the combination of a fixed plate or
base with a second plate pivotted to the base having a hook, the arrangement
being such that a loop knot is formed around the hook by passing the thread
under and over the same, and cut at the loop part by the hook, substantially as
described.
(2) In a thread knotting and cutting device, the combination of a fixed plate or
base, over and around which the thread is passed, with a second plate pivotted to
it and furnished with a hook, and a spring pressing the plate up against the top of
the fixed plate, the thread passing over and under the hook, and forming a loop
knot around it when pulled, which is cut by it on further pulling, forming a knot
on one of the cut parts, substantially as described.
(3) In a thread knotting and cutting device, the combination of a fixed or base
plate, with a second plate, pivotted to the base plate, and furnished with a hook, a

page_text: spring bearing on said plate and tending to raise it, and a shoulder, which, when
moved, depresses the plate and hook, the thread passing over the fixed plate
around the shoulder and under the hook, forming when pulled a loop knot
around the latter, cut through the loop by it when further pulled, substantially
as described.
(4) In a thread knotting and cutting device, the combination of a fixed or base
plate having a flange at top, forming a guide for the thread, and a slit at the angle
of the flange, for the greater part of its length, with a second plate pivotted to the
first having a hook on its face, a nose or shoulder at its front end, and a shoulder
at its rear, projecting beyond the back of the fixed plate, and a spring bearing
against the plate, and pressing the hook against the top of the latter, the thread
being passed in front of the nose at the front, over the fixed plate, around the
shoulder, and under the hook, forming, when pulled, a loop knot around the hook,
cut by it on further pulling, substantially as described.
(5) In a thread knotter and cutter the combination of a fixed plate C, having a
bent over part cat top with slit c¹ and a guide Cat the front, with a plate D
having nose d, and shoulder d', a hook E on the said plate, and a spring E
bearing against it and pressing the hook against the parts c, the thread being
passed in front of the nose d over the back of the plate C, around the shoulder di
and under the hook E, forming a loop knot around the latter, substantially as
described and illustrated in the sheet of drawings.
(6) In a thread knotter and cutter, the combination of a spring shank B, by
which the device is attached to a reel or the like, having a head or base plate C
furnished with guides C' and c, and slit c¹ with a plate D having nose d and
shoulder d', a hook E on said plate, and a spring F bearing against it, and pressing
the hook against the guide c, the thread being passed in front of the nose d, over
the top and back of the plate C, around the shoulder d', and under the hook E,
forming a loop knot around the latter, substantially as described and shown.
(7) In a thread knotter and cutter, the combination of a spring shank B, by
which the device is attached to a reel or the like, and a head or base plate C
furnished with guides C¹ and c, the latter with slit c and the projection c³, with
plate D having nose d and shoulder d', hook E on said plate, and spring F, the
thread being passed over the projection, or guide c³, thence over guide C¹, around
back of plate C and shoulder and under the hook E, forming a loop knot around
the latter, substantially as described and illustrated in the drawings.
