The nature and charactertistic features ofthe
25 present invention will be more readily understood
from the following description takenin connec
tion with the accompanying drawingl forming
part hereof, in which:

Referring to the drawi1ig,the heddle frame there
shown comprises top and bottom rails lil,L usually
made oi vvood,` and connected at their ends by
means of the metallic side strips Il. Extending
from end to end of the heddleframe andvar
55 ranged near the` top and bottom rails Hlffare the
sleeve` member 3€I= preferably made from sheet
metal'punched’and formed to they proper shape.
The-shank portion of the bolt member is pro- 20
vided‘wíth. struck-up lugs 2li-.to provide shoulders
against which one end ofthe coil spring 25 bears.
The other end 'of >the coil spring bears against >the
sleeve member 30 which is mounted on the head
portion 2.3.-‘ofr thecbolt member, the spring im- 25
pelling thissleeve member 3u toward the end
of the‘head-portion 23.v of the` bolt member.
The head portion 234 of` thebolt member is also
providedwith a widened portion 26, thus pro
vidingfa shoulder.'g2»'l\vvhichI serves» as a limit for 30
the movementofï the sleeve member, preventing
the` same from beingimpelled too far toward the
end of- the head portion 23 of the boltmember.
The portion iof theV sleeve member 30 which ex
tends around the narrow part of the head portion 35
23` of the» bolt member’is-so‘. formed as to make a
snug, slidingiñt` with respect thereto.
The widenedpart 2620i the head portion 23 of
the bolt memberis=also=provided With a recess >28’:
for` the reception ofthe heddle supporting bar 40
I2. The sleeve member.- 3l'l‘is> also` provided with
parallel-extensions-S'L disposed on each side of
thehead-portion` 230i the bolt member and each
provided with a recess 32 adapted to `engage one

In -theuse of: the device, Whenever it is desired

22
the ears 33 of the sleeve member 30 are engaged
by the ñngers of the operator and the sleeve
member 3l) thereby withdrawn, so that the ends
of the recessed extensions 3l are brought to a
position to free the recess 26 in the head portion
23 of the bolt member; whereupon the heddle
supporting bar I2 may be freely inserted or re
moved, as the case may be. Whenthe heddle
supporting bar l2 is in its proper position within
10 the recess 28 of the head portion 23 of the bolt
member and the sleeve member 30 is released
by the operator, the recessed extensions 3l of said
sleeve member 30 will engage the heddle bar on
both sides of the head portion 23 of the bolt mem
15 ber, thus providing a lock on each side of said
head portion. The provision of the two ears 33
on each side of the sleeve member 30 enables the
operator to control the same quite easily, it being
noted that the pressures and forces exerted are
20 symmetrical at all times, so that said sleeve mem
ber 30 will be freely operable and- will not tend
to stick or jam.
In the form of the device shown in Figs. 'l and
8 of the drawing the struck-up lug portions 24
25 on the shank 2l of the bolt member are omitted,
and in lieu thereof the shank portion 2| of the
bolt member is provided with a machine screw
thread 29 upon which a thumb nut 40 is com
plementally threaded. The thumb nut 40 is re
30 cessed as at 4l for reception ofV the end of the
coil spring 25, this recess being of suiiìcient extent
so that when the thumb nut 4D is Screwed down,
the said coil spring 25 will be contained entirely
within the same, and the rim of the thumb nut
35 40 will bear directly against a washer 42 which
is interposed between the lower end of the spring
25 and the upper end of the sleeve member 30.
In this manner the sleeve member 30 may be
positively locked in position by means of the
thumb nut 40 to the end that accidental disen
40
gagement of the heddle supporting bar l2 from
the head portion 23 of the bolt member will be
prevented.
