6 Claims.
(01. 139-185)‘
Shuttle checks or binders for looms are known
which are movable by the shuttle when it enters
the shuttle-box thus to move to idle or inactive
position means for stopping the loom which
5 otherwise (or if the shuttle failed to enter the
box) would effect such stopping. Varying condi
tions in weaving as well as varying conditions in
different looms‘ make it desirable to provide a
check which can be adjusted so as to have it ac
10 tuated by the shuttle, and hence move the stop
ping means to idle position, at different points
in the shuttle’s path of approach to its ?nal po—
sition in the box. Such a check is the subject of
the present invention. It is characterized by an
15 elongated shoe which coacts with the back of the
box to stop the shuttle and which is adapted, by
force applied at or near its end which adjoins the
entrance of the box, to be bent more or less away
from said back wall, and by novel adjustable
lgo means for determining the extent of and main
taining such bend. The extent of the bend de
termines, as will appear, the point in the shuttle’s
path of approach to its ?nal position in the box,
at which the shuttle acts through the check to
,25 actuate the stopping means. The. construction is
such also that said shoe may be adjusted bodily
toward or from said wall of the box, thus to ac
commodate shuttles of varying sizes.
In the drawing,

Fig. 1 is a planof the improved check, with the
back wall of the shuttle box and a shuttle shown
by dotted lines;

the former in vertical section and the bolt and
35 nut in elevation; and

a designates the ‘back wall of the shuttle box
and b the shuttle in the space of the box formed
by said wall and the improved check, which latter

is constructed as follows:
,
l is an elongated body member, being in?exible
and having an eye 2 at the end thereof adjoin
ing the outer end of the box to receive a bolt la
of the box, the other or entrance end of said
member (being the end at the entrance end of
the box) being adapted to be limited as to dis
placement from said wall by another bolt lb of
the box arranged to traverse said end as usual.
The mentioned stopping means to be moved by
50 the check to inactive position on the shuttle en
tering the box engages the outer face of member I
at the left-hand end in Fig. 1, such means being
not shown.
3 is the shoe member consisting of a steel strip
55 of somewhat shorter length than the member I
‘
,.
and having‘ about the same width but less thick
ness than such member.
It may be flexed but -
preferably is not adapted‘ to undergo flexion by
either the‘ impact or the pressure of the shuttle.
It extends‘le'ngthwise and opposite to the mem- ,;~5
ber .l with one‘ end terminating slightly short of
the outer end, but its other end terminating here
appreciably short of the entrance end, of said
member. U-shaped elements 4 project from the
outer face of the shoe member in offset relation to {10
each other lengthwise thereof, being here integral
portions of a-metal strip 5 secured by rivets 8 to
said face, each such element having a slot 411.
These elements are within that lengthwise half of
the shoe member which includes its outer end. 515
When in use the shoe member will have generally
the form shown by Fig. 1, to wit: So that'from
its outer end to a point past the left-hand'ele
ment 4 in Fig. 1 its inner face will be lengthwise
substantially straight, as at 1, and so that from ,20
such point nearly to its other or- entrance end
said face will be convex, as at 8,'the remaining or
terminal portion 9 of said- face being again
straight and about parallel with the face .1. The
entrance terminal of the shoe-member has a hole 625
I0.

Screws “are screwed into the body member
and respectively penetrate the slots Ila in ele
ments 4, their heads being con?ned between said
elements and the strip or body portion of the 30
shoe member; said screws have lock-nuts l2 to
bear against the outer face of the body member.
The mentioned supporting structure includes,
with the body member, an adjusting screw i3
screwed into said body member opposite the en- 35
trance terminal of the shoe member and having
a polygonal head l3a for turning it. Ill is a bolt
and IS a nut thereon for clamping the shoe mem
ber and said structure together; in this example,
and preferably, the screw device is bored and the 40
bolt penetrates its bore.
Adjustments in several ways are possible.
Thus, by rotating both screws H and the screw
device in the same direction the shoe member '
may be adjusted toward or from the supporting 45
structure bodily. Or, the screws being set so that
the face 1 of the shoe member is properly spaced
from the wall I) of the box to suit the particular
shuttle, the screw device may be turned in the
.appropriate direction so that the entrance ter- 50
minal of the shoe member when clamped will
have a de?nite spacing from the supporting
structure, involving flexing distortion of said shoe
member. Or, the entrance end of the shoe mem
ber remaining clamped, the screws ll may be 55

turned in the appropriate direction to space the
portion of the shoe member having the face "I
away from the supporting structure as‘ required,
such also involving ?exing distortion of the shoe
member. Of course, whenever the screw device
is to be turned the clamping means I4, I5 is
released.
to said device, to clamp fast together the shoe
As the shoe member appears in Fig. l the line
of juncture between the straight face 8 and the
10 convex face 9 of the shoe member is at about the
arrow 9:. But this line of juncture will shift to
the right or left the more or less, respectively, as
the shoe member is ?exed. The degree of ?exion
of the shoe member, then, determines the point
15 in the ?ight of the shuttle where the check will
move the stopping mechanism to position to
avoid stopping the loom. Thus:
As shown, the shuttle being in the box and
holding the checl; at its outward limit or against
20 bolt lb, the mentioned stopping means has been
moved to inactive position. When the shuttle is
out of the box said means shifts the check around
bolt I a as a pivot toward the back wall of the box.
On the shuttle now entering the box with the
25 check in the last-named position it will engage
and move back the check (and hence shift the
stopping means to inactive position) at some
selected point in its ?ight depending on the de
gree of ?exion which has been formed in the shoe
30 member.
The actual stopping of the shuttle, it will be
understood, is effected ‘by the friction incident to
contact of the shuttle with the face 1 of the shoe
member and the back wall of the box, between
35 which it snugly ?ts when the check is at its out
ward limit.
It is important, due to the tendency of the metal
of the shoe members of shuttle checks to crystal
lize, not unduly to weaken the shoe member by
holes therein. No such holes, excepting the rela
tively small hole l0, exists in the shoe member of
the present check.
Having thus fully described our invention what
we claim is:

an elongated shoe member beside and extending
lengthwise of the body member and having the
end portion corresponding to said end portion of
the body member bent toward the body member 5
and bearing against said device, means, adjacent
