Improvements in Loom Shuttles.
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 reliable in action.
To this end 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 leading to a recess 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
serve to prevent the thread jumping out when swirling or ballooning during the
working of the shuttle.
In order to guide the thread from the aforesaid hole to the said slot, I employ
in the recess between the inner ends of the same a pin, stud or wire or the like which
is flush with the inner side of the said slot and has a crescent shaped head the
concave part of which is opposite the inner end of the aforesaid slit.
The concave part of the said crescent shaped head is adapted to receive the thread
in case the latter gets over the top of the said head in weaving and thus prevent
same entangling around the said pin or the like.
In order to guard against the thread leaving the said slot when the shuttle is working
I employ an open ring or eye coiled of a piece of wire the ends of which extend passed
each other. The said ring or eye I fix in position by driving one end into the shuttle
side, in such a way that its open part communicates with the said slot and allows
of placing the thread into the ring or eye.
The other end of the said ring or eye at the outer side of the shuttle reaches
below the bottom of the ring or eye to prevent the thread leaving it when the shuttle
is working.
The shuttle is threaded by passing the thread through the said slit, partially
round the said pin or the like and afterwards through the said slot into the said
ring or eye, the head on the said 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 said slot. .
To further facilitate and ensure the thread entering the said slot and eye and
prevent the warn threads catching and sometimes breaking I bevel or round off the
edges of the said slot.

I, CARL HERRMANN ROTH, of 2, North Parade, Manchester, in the County of
Lancaster, Machinery Exporter, 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 that type of loom shuttle 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 devices so as
to be produced cheaper and at the same time be more reliable in action.
And in order that my invention may be more fully understood I have caused to
be appended hereunto one sheet of drawings marked with letters of reference
indicating like parts in the various figures.
Fig. 1 is a side view, Fig. 2 a plan, Fig. 3 a plan in section, and Fig. 4 a longi-
tudinal section of the fore part of a shuttle with my improvements applied. Fig. 5
is a view at an enlarged scale of a detail.
a
In carrying out my invention and referring to the figures generally in lieu of
forming opposite to the nose of the cop a or the point of the shuttle tongue
recess as hitherto, I form a conical or bell shaped cavity with a hole d in continu-
ation thereof leading to a recess e communicating with the aforesaid slot f in the
shuttle.
Through the upper wall of the cavity and hole d I form a slit 9 through which
the thread is placed into the said hole and cavity which latter serve to prevent the
thread jumping out when swirling or ballooning during the working of the shuttle.
In order to guide the thread from the hole d to the slot f, I employ in the recess e
between the inner ends of the said hole and slot, a pin stud or wire or the like h
which is flush with the inner side of the said slot and has a crescent shaped head h¹,
the concave part 2 of which is opposite the inner end of the slit g.
The said concave part of the crescent shaped head h¹ is adapted to receive the
thread in case the latter gets over the top of the said head in weaving and thus
prevent same entangling around the said pin or the like; in shuttles for some
classes of looms the concave part h² may however be dispensed with, i.e. the head h¹
may be formed round.
In order to guard against the thread leaving the slot f when the shuttle is work-
ing, I employ in the passage f¹ below the same an open spiral or eye i coiled of a
piece of wire. The spiral or eye i I fix in position by driving one end into the
shuttle side, in such a way that its open part communicates with the slot f and
allows of placing the thread into the spiral or eye i.
The other or free end of the said spiral or eye reaches below the inside diameter
of the latter so as to prevent the thread leaving it when the shuttle is working.
The shuttle is threaded by passing the thread through the slit g, partially round
the pin or the like h, h¹, and afterwards through the slot f into the spiral or eye i
the head on the said 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 slot f.
To further facilitate and ensure the thread entering the slot f and spiral or eye i
and prevent the warp threads catching and sometimes breaking I bevel or round off
"the edges of the slot. £

page_text: Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:-
1st. In a loom shuttle having a threading slot f, a slit g communicating with a
hole d formed in the body of the shuttle opposite the nose of the cop a or point of
the shuttle tongue 6, all substantially as and for the purpose set forth.
2nd. In combination with the slot f and hole d, specified in the preceding claim,
a pin or the like h having a head h¹ secured into a recess e formed in the body of
the shuttle communicating with the said slot and hole, all substantially as and for
the purpose set forth.
3rd. In combination with the outer end of the slot f, specified in the preceding
claims, a spiral or eye i communicating therewith and having one end reaching
below its interior diameter, all substantially as set forth.
