I, CARL HERRMANN ROTH, of 2, North Parade, Manchester, in the County of
Lancaster, Machinery Exporter, do hereby declare the nature of this invention to
be as follows:-
This invention relates to that type of loom shuttles wherein a slot is formed in
connection with the shuttle eye and means employed for guiding the thread,
through the said slot, into the eye, in lieu of sucking it through.
The object of my invention is to simplify the said type of threading device so as
to be produced cheaper and at the same time be more certain in action.
To this end I fix at the thread entrance, flush with the inner side of the said
slot a piece of metal or other suitable material, in the shape of a pin, stud, peg,
nail, screw or the like, having a head of round, oval or irregular form.
In order to guard against the thread leaving the said slot when the shuttle is
working, I employ an open ring coiled of a piece of wire the ends of which extend
passed each other. The said ring I fix in position by driving its outer end into
the shuttle side, its open part being adapted to communicate with the said slot so as
to allow of the thread entering the said ring. The inner end of the said ring is
situated near the bottom and bent below or behind the adjacent part sufficient to
prevent the thread leaving the said ring or eye when the shuttle is working.
In lieu of forming opposite to the nose of the cop or the point of the shuttle
tongue a recess as hitherto, I form a conical or bell shaped cavity with a hole in
continuation thereof communicating with the aforesaid slot in the shuttle. Through
the upper wall of the said cavity and hole I form a slit through which the thread
is placed into the said hole and cavity which latter prevent the thread jumping
over the head of the said pin or the like, when swirling or ballooning during the
working of the shuttle.
The shuttle is threaded by passing the thread through the said slit, partially
round the shank of the said pin and afterwards through the said slot into the said
ring or eye, the head on the said pin being at such a height as to catch and
prevent the thread from slipping off and thus guide and ensure the same entering
the said slot.
To further facilitate and ensure the thread entering the said slot and eye and
prevent the warp threads catching and sometimes breaking I bevel or round off the
edges of the said slot.

page_text: Fig. 5 is a view at an enlarged scale of a detail.
In carrying out my invention and referring to the figures generally I fix at the
thread entrance, flush with the inner side of the said slot a, a piece of metal or other
suitable material, in the shape of a pin, stud, peg, nail, screw or the like b, having a
head of round, oval or irregular form.
In order to guard against the thread leaving the threading slot a when the shuttle
is working, I employ an open spiral ring c coiled of a piece of wire the ends of
which extend passed each other, see more particularly Fig. 5. The said ring I fix in
position by driving its outer end into the shuttle side, its open part being adapted to
communicate with the said slot so as to allow of the thread entering the ring c. The
inner end of the said ring is situated near the bottom and bent below or behind its
adjacent part sufficient, to prevent the thread leaving the ring c when the shuttle is
working.
In lieu of forming opposite to the nose of the cop or the point of the shuttle
tongue d or thereabouts, a recess as hitherto, I form a conical or bell shaped cavity e
with a hole f in continuation thereof communicating with the threading slot a in the
shuttle. Through the upper wall of the said cavity and hole I form a slit g through
which the thread is placed into the hole and cavity, which latter prevent the thread
jumping over the head of the said pin or the like b, when swirling or ballooning during
the working of the shuttle.
The shuttle is threaded by passing the thread through the said slit, partially
round the shank of the pin or the like band afterwards through the threading slot a
into the ring c, the head b¹ on the pin or the like being at such a height as to
catch and prevent the thread from slipping off and thus guide and ensure the same
entering the threading slot c.
To further facilitate and ensure the thread entering the said slot and eye and
prevent the warp threads catching and sometimes breaking I bevel or round off
the edges of the said slot.
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 :-
1st. A loom shuttle having a threading slot a and an open ring c at its outer end,
all substantially as and for the purpose set forth.

page_text: 2nd. A loom shuttle having a threading slot a, a pin 6 fixed flush with the inner
end of the said slot and having a head b¹ and an open ring c at the outer end of the
slot, a, all substantially as and for the purpose set forth.
3rd. A loom shuttle having a threading slot a, a pin b fixed flush with the inner
end of the said slot and having a head b¹, an open ring c at the outer end of the
slot a, and a cavity e ending in a hole f communicating with the inner end of the
slot a, the upper wall of which cavity and hole has a slit g, all substantially as and
for the purpose set forth.
Dated this 13th day of January 1898.
