3 Claims. (Cl. 139—187)
My invention relates to releases for ?y shuttle
type looms and the improvement of which is fully
set forth in the following speci?cation and claims.
The general object of the invention is to pro
5 vide means whereby the shuttle tension means
are released just before the shuttle leaves the
box, such means including a roller carrying mem
ber attached to an arm on the tension shaft and
a pivoted cam member having means for sup
10 porting it from a part of the frame of the loom.
In order that the principle of the invention may

shaped jack lever, the vertical part of which is
shown at I9 and the horizontal part at 2!], the
pivot 24 passing through the junction of the two
parts and through the lower ends of the com
panion parts of the bracket. The top part of the
bracket has a slot therein which communicates
be readily understood, I have disclosed a single
with the space between the depending parts and
the part I9 of the jack extends through the slot
and the upper end of this part I9 has the cam
head I8 thereon. A spring 2| engages a part of 10
the bracket and the outer end of the part 20
and tends to hold the jack in tilted position as
embodiment thereof in the accompanying draw
ings and a break down generally of its several
shown in Figures 1 and 3.
The parts are so arranged that as the lay nears

In the drawings:Figure 1 is a fragmentary View partly in trans
verse section and partly in elevation showing the
end of the loom and a rock shaft mounting with
20 part of the invention connected to the protection
rod and the other part to the loom end.
Figure 2 is a View partly in front elevation and
partly in section taken on the line 2—2 of Fig

30 mg.
Figure 5 is a perspective view of the roller shaft
mounting with a slot in it for adjustment.
In these drawings, a part of the frame of the
loom is shown at I, the sword at 2 and the lay
35 at 3. A tension or presser ?nger is shown at 4
which is connected with the spring actuated rock
shaft 5, the binder being shown at ‘I for applying
pressure to the shuttle 8 in the box, a portion of
which is shown at 9. All of these parts are of
40 the well known type and form no part of my
invention.
In carrying out my invention I attach a bracket
H to an arm 6 on the shaft 5 and said bracket
has an elongated slot therein for receiving the
45 bolts III which also pass through the arm 6 so
that the bracket is adjustably connected with the
arm. A threaded shank I3 is threaded in a- hole
I2 in the outer end of the bracket and a nut Ill
holds the shaft in adjusted position in the bracket.
50 The lower end of the shaft carries a forked mem
ber I5 and a roller I1 is carried by said member.
A bracket 22 is adjustably connected to a part
of the frame I by a bolt passing through a slot
23 in the bracket and said bracket has a pair of
55 depending parts between which extends an angle
the shaft 5 to rock in a direction to cause the arm
4 to release the tension on the shuttle in the box
so that the shuttle can easily leave the box. On
the forward motion of the lay the jack will tilt 20
against the action of its spring, when engaged by
the roller, as shown in dotted lines in Figure 1
and this prevents damage to the loom parts should
the shuttle fail to box for any reason.
As will be seen in the normal position of the 25
jack the head I8 slopes upwardly and forwardly
with the part I9 at a slight inclination and the
forward end of the head is beveled as shown more
particularly in Figure 8.
It is thought that the construction, operation,
utility and advantages of this invention will now
be quite apparent to those skilled in this art with
out a more detailed description thereof.
The present embodiment of the invention has
been described in considerable detail merely for
the purposes of exempli?caticn and it is to be
understood that modi?cations of details described
may be resorted to within the scope of the ap
pended claims since in actual practice it attains 40
the features of advantage enumerated as desir
able in the statement of the invention and the
above description.
I claim:
1. In combination with the shuttle tension 45
means of a loom including- a tension shaft, a
bracket extending forwardly from the shaft, a
roller carrying member depending fromv the
bracket, a second bracket supported from the loom
frame, a cam head having a shank depending 50
therefrom, the lower end of the shank being piv~
otally supported in the bracket, yieldable means
for holding the shank in a tilted position with the
shank extending upwardly and rearwardly and
with the head sloping upwardly and forwardly, 55

said head being engaged by the roller during the
3. In combination with the shuttle tension
movement of the loom parts.
2. In combination with the shuttle tension
means of a loom including a tension shaft, and
means of a loom including a tension shaft, an
arm connected with the shaft, a bracket, means
for a?ustably connecting the bracket with the
an arm on the shaft, a bracket adjustably con
arm, a shaft depending from the bracket, means
nected with the arm, a depending shaft connected
end of the shaft, a second bracket adjustably con
for adjustably connecting the shaft with the
bracket, a roller at the lower end of the shaft, a
second bracket connected with the loom frame, a
nected with the loom frame, a cam head having
bellcrank member pivoted in the second bracket
with the bracket, a roller supported at the lower
10 a depending shank, means for pivotally connect
ing the lower end of the shank in the second
bracket and means. including yieldable means for
permitting the shank to tilt when engaged by the
roller on the forward movement of the lay, the
15 head of the shank causing upward movement of
the roller carrying parts when said roller engages
the head on the rearward movement of the lay.
and including an upstanding part having a cam 10
head thereon, a spring having a part engaging the
horizontal portion of the bellcrank and a part of
the bracket for permitting movement of the bell
crank in one direction, parts of the bracket pre
venting movement of the bellcrank in an opposite 15
direction when engaged by the roller.
