6 Claims.
invention relates to shuttles, particularly
of the hand threading type, and is substantially
a ‘one piece Shuttle ‘eye b100k ‘Which takes the
place of a tubular, transverse, horizontal, porce~
{5; Iain or metal eye, and of the vertical outlet pin
or pins of porcelain or metal now in common
use with such shuttles.
kIts principal advantages are that there are no
pins or other parts which can come out and cut
t0 the warp, and that it can be made of one piece
of ‘porcelain, hard steel, stainless steel, chromi-

thread can be quickly brought down through a

the front of an eye inlet in the block which preferably extends down and then up into the bottom
of a transverse eye passage, the wood being so cut
that while the thread can readily get into. the eye,
‘40 it cannot readily get out of the eye.
All parts of the block which the thread touches
are smooth, hard and curved, and except when
threading, the thread touches no part of the wood
except along the usual thread groove in the side
4,5 of the shuttle, whereby catching, wearing and
shiners‘are avoided.

however. The plastic wood P is then pressed in
place to leave a smooth top.
I4 is the transverse eye passage through block
B positioned in alignment with eye hole 4 and
eye groove 5 and particularly the part 3. There
is an inlet I5 in the bottom of eye passage l4,
and in front of the vertical wall It, which extends
down below and then up at the mouth [3 above
the bottom of the eye inlet slot 3 in the wood.
As shown in Fig. 7, the wood is so cut that
10
there is enough space around the bottom front of
the eye block B to allow the thread to go down
from the eye inlet slot’ in the wood into the eye
pasage I4 and eye hole 4 which together form the
.
'
15 shuttle eye.
A convenient way to make an eye 4 and to
leave space enough around mouth i3 is to bore
a transverse hole H34 in the wood and then block
part of it up at R.
As shown in Fig. 8, in a hand threading shut
20
tle, there. can be cut a threading slot 22 in
which there is no metal friction such as A, but
in which there is a thread pin 27 in the angle
between the threading slot 22 and the eye inlet
25 slot 23. Block B and the other parts of the wood
are the same as in Fig. 1.
The shapes of the eye block and the methods
of looking it in place to prevent vertical displace
ment, are shown in Figs. 9, 10, and 11.
In Fig. 9, the block F has the bottom 3!
30
which is wider than the bottom H of B, while
the mouth 33 at the front 32 is not as high. The
front wall 32 and back wall 31 are rounded, as are
also the walls of the inlet 35 for transverse pas
35 sage 34, while the top 38 of the mouth 33 slopes
upward and the block is held in place by a strip
30 held down by _a screw 20, the‘ top part 88 of
the block. recess being lengthened out toward the
back to accommodate them.
40
In Fig. 10, G shows another modi?cation of the
eye block with‘ a curved front wall 42 and back
wall 41, ?at top 49 and bottom 4! from which ex
tends upward the inlet passage 45 for transverse
eye passage 44. The front part 48 of the bottom
4.5 4!, which is an extension of the inlet 45, extends
up and forward to form a mouth 43, while the
block recess I48 is so cut that the back and front
walls 41 and 42 and the rear part of the bottom
4| ?t it, the bottom l4! keeping the block G in
place. At the top- is shown a locking device in
50
the form of wire legs 40 which, when bent down
as shown by the dotted lines, penetrate the wood,
holding block G down in position.
In Fig. 11, the block recess can be the same as
55 8 while the block H has a curved front wall 52
and back wall 51, the bottom 5| extending from
front to back the same distance as top 59,
there being a transverse eye passage 54 with an
inlet passage 35 which extends down under the
60 wall 58 and out at a mouth 53. Block H is held
down and in position by the head of a screw 50,
'the top of the block recess being extended at 88,
as it is also shown in Fig. 9.
In Figs. 12 and 13, the inlet slot 63 in the wood
goes
down somewhat lower than in Fig. l, and
65
extends back horizontally as shown in Fig. 12, and
then up at 64.
The block K has a horizontal inlet passage 60
which connects with or is formed as an inlet SI
70 for the transverse eye passage 62. The eye block
with a thread groove 66 in the side of the shuttle,
65 represents the block recess in which block K
rests.
As shown in Figs. 8 and 14, I prefer to make
the block recess such as I I2 at a slight angle with
the vertical plane through the axis of the shut
tle whereby the front and back walls of the
transverse eye passage, such as [4, or their edges
I I4 and 2 l4 contract the passage and serve to re
tard the thread T as it runs through. More 10
over, by making this recess at a slight angle with
the vertical, and substantially parallel with the
slope of the adjoining part of the shuttle, as
shown in Fig. 8 and Fig. 14, the wood of the
shuttle between the front of the block and the 15
side of the shuttle is weakened less than if it was
parallel with the axis.
Block recess H2 must be enlarged at 204 to al
low the thread to go around the front of block B
into mouth l3 and passage l4. However, as 20
shown in Fig. 15, in place of such enlargement,
the front 10 of an eye block M may be made
narrower to leave room between M and the wall
of block recess ‘H.
I claim:
_

1. The combination in a shuttle having an eye
inlet slot which connects with an eye hole in the
side of the shuttle, an eye block recess which ex

transverse eye passage at an angle between the
eye hole and the thread pin, there being an inlet
at the bottom of the eye passage which extends
down and thence forward and at its mouth
above the bottom of the eye inlet slot, there be
ing enough space around the bottom front and
the outside of the eye block to allow the thread to 40
go from the eye inlet into] the eye passage in the
eye block.
2. The combination in a shuttle having a body
in which is an eye inlet slot which connects with
an eye hole and a thread recess in the side of
the shuttle, an eye block recess which extends
