HEDDLE BAR LOCKING SYSTEM FOR HED
DLE FRAMES AND THE LIKE
George F. Bahan, Charlotte, N. 0.
Application April 20, 1936, Serial No. 75,433
10 Claims. (Cl. 139-412)
This invention relates to a heddle bar locking
system for heddle frames and the like and more
spreading from its normal position, especially on
long and wide frames.
especially to a locking system comprising a plu
rality of hooked members located in spaced re
5 lation on the heddle frame for removably sup
porting. the heddle bar. Each of the hooked
membersiwhich holds the heddle bar in position
has an alternating over-lapping hooked portion.
It is a further object of this invention to pro
vide a heddle frame with a. bracing bar having a
For example, the over-lapping portion over-laps
10 the lower side of the bar on the ?rst hook and the
upper portion of the bar on the second hook, and
so on, thereby holding the heddle bar in rigid
position within the hooks. It is evident by using
a device of this type that no Slide movements,
15 springs or nuts are necessary to securely lock the
heddle bar in position, since the over-lapping
portions of the hook members engage ?rst one
side of the bar and then the other to hold the
bar in rigid position.
20
It is therefore an object of this invention to
provide a one-piece bar lock having a notch
therein for accommodating the heddle bar, which
bar lock cooperates with a. second one-piece bar
lock also having a. notch therein alined with said
?rst notch for accommodating the heddle bar,
each of said ?rst and second bars having an
overlapping notch therein communicating with
the alined notches, said overlapping notches be
ing staggered with respect to the heddle bar to
30 con?ne! the edges of the bar within the alined
notches.
It is a further object of this invention to pro
vide a locking system for heddle bars comprising
one member having a hooked effect on the bot
tom with a notch in said member adjoining said
hook for accommodating a heddle bar, and sec
ond member having a notch therein for accom
modating the heddle bar with a hook eifect on
the upper side of said bar, to cause the heddle
40 bar to be held in rigid position within both of
said notches. The bar is held in position in the
?rst locking member by the hooked effect on the
bottom and the sized space or notch on the top
to conform to the exact size of the heddle bar.
45 The bar is held in position in the second locking
member by the hooked effect on top and the
sized space on the bottom conforming to the
exact size of the bar.
'
It is another object of this invention to provide
a heddle frame with a bracing bar which is en
dowed with the same features as the bar looks
just described and which is adapted to cooperate
with the other locking means. The bracing bar
55 is provided to keep the frame from springing or
one-piece locking system. incorporated therein,
with means for quickly attaching and detaching
the same from the heddle frame without the ne
cessity of loosening nuts, bolts and the like. This
bar is made quickly detachable from the frame
by providing a suitable cavity at each end there
of, in which a spring pressed ball is adapted to‘
?t, the ends of said bracing bar having trans
verse open-ended slots therein adapted to ?t over
suitable pins, which pins are connected to a suit
able bolt secured in opposed rail members of the
heddle frame. The ball and cavity prevents the
bar from becoming disengaged from the pins
and also prevents vibration of the same, taking
strains off the heddles at the point where a
springing or bulging of the frame might occur. 20
Some of the objects of the invention having
been stated other objects will appear as the de
scription proceeds when taken in connection
with the accompanying drawings in which-—

Referring more speci?cally to the drawings,
the numerals l0 and l I indicate the upper and
lower bars of a heddle frame which has secured '
2
2,108,095
to each end thereof for forming the corners of
the heddle frame, straps I3 and I4. These strap-s
have suitable holes in the ends thereof which
are penetrated by stud bolts i5, said stud bolts
having their ends threadably secured in the ends
of bars ii. A tubular spacer i5 is disposed be
tween the straps l3 and i4 and this spacer is also
and like reference characters will be given like
parts. Also the bars 20' and 2|’ have notches
therein identical to the notches in bars 20 and
2| and a repeated description is not deemed nec
essary since they perform the same function.
In order to insert or to remove the heddle bars
25 from their respective notches, it is necessary
penetrated by the stud bolts l6. By constructing
to engage the bar at a point near one of the
the corner of the heddle frame in the manner
locking lugs and spring the bar axially until
10 shown it is possible to obtain a very rigid frame
work which will prevent distortion or unnecessary
Vibration.
Secured to the upper bar ill are bar locks 20,
2:, 2i’ and 25’, the members 2|’ and 20' being
15 identical to the members 2| and 20. Disposed
near the central portion of the frame is an inter
mediate brace 22 which connects the upper and
lower bars I9 and H. This bar also has a
locking means incorporated therein similar to
the locking means shown in bar 2| .
The bars
25, 2i, 22, 2!’ and 25’ cooperate with each
other to hold the heddle bars 25 in the position
shown in Figure 1.
Likewise the lower bar H has bar locks 26, 21,
25 2i’ and 25’ secured to the upper portion thereof
for holding the lower heddle bar 28 in the posi
tion shown in Figure 1. The central portion of
the bar 28 is also engaged by the locking means
on the lower end of strut or brace 22.
The form of locking means shown in Figs. 1
to 5 inclusive is for a double heddle frame; how
ever since the locking means for both sides of
the frame is identical in all respects, like reference
characters will apply to similar parts on both sides
35 of the frame.
By referring to Figure 2, it is seen that the
locking bar 25 has a pair of overlapping notches
cut in each side thereof in which the heddle bars
25 are adapted to be inserted. The ?rst notch
40 is out between shoulders 30 and 3| which is
slightly wider than bar 25, and. then the notch
is offset in a downward direction and has com
municating therewith an overlapping notch
which is disposed between shoulders 32 and 33.
has an upwardly inclined beveled
45 The shoulder
surface 34 adjoining this notch. This beveled
surface is provided in order to facilitate the in
sertion of the heddle bar 25 within the notch
disposed between shoulders 32 and 33 to occupy
50 the position shown in Figure 2. If desired the
surface 35 may also be beveled, however it is
not so essential as the beveling of surface 34.
It should be noted in Figure 2 that a hooked
portion overlaps the lower edge of bar 25 to con
55 ?ne this edge within the notch, whereas the upper
portion is not confined but can be pulled laterally
in order to remove the bar.
In Figure 3 the locking bar 2| is shown en
gaging the same heddle bars 25. The locking
60 means in this bar is constructed along similar
lines, however it should be noted that the over
lapping hooked portion of this notch is disposed
on the upper side of the bar 25. This locking
means comprises a notch out between the shoul
65 ders 3i and 38 which is slightly wider than the
width of the bar 25. Adjoining this notch is
another notch which is offset upwardly which is
disposed between the shoulders 39 and 40. A
beveled surface 4| is disposed adjacent the shoul
70 der 39 which is provided in order to facilitate
the insertion of bar 25 within the notch disposed
between the shoulders 39 and 40.
Likewise a
beveled surface 42 may be provided if desired.
The notches for locking the bars 25 in the ball
75 22 are identical to the notches shown in bar 2|
one edge thereof can be removed from the notch.
For example, if it is desired to remove the bar
25 from. the locking means in bar 20, it is neces
sary to spring the upper portion of bar 25 out
wardly from the center of the frame and then
push the bar upwardly until it is disengaged
from the notch. At the same time this same
bar will be engaged by the locking means incor
porated in the lug or member 2|. In order to
remove the bar from this notch it is then. neces
sary to engage the bar at a point near this locking 20
means and spring the lower portion thereof axial
ly outwardly from the center line of the frame
and then pull the bar downwardly. This opera
tion is repeated until the bar is removed from
all the notches across the frame. Since it is 25
necessary to spring the bar axially in order to
insert it within the notches in the members 20,
2!, 22, 20’ and 2|’, it is evident that after bars
have once been inserted in these notches that
the bars will remain in position, since the bars 30
have the required amount of resiliency. There
fore by having the overlapping portions in one
of the bar locks overlapping the lower side of
the heddle bar and the overlapping portions for
the succeeding bar overlapping the upper side of 35
the bar, it is possible to hold the bar in a rigid
position .at all times without the necessity of
providing an extra member to accomplish this
purpose.
The heddle bars 28 in the lower portion of the
frame are held in identically the same manner as
the heddle bars in the upper portion of the frame,
that is, the same principle is involved by provid
ing alternate overlapping projections for sup
porting the heddle bar. The repeated description
of the mounting of the lower bars 28 will not be
made since the upper bar 25 has been described
in detail, but similar notches will be given similar
reference characters.
In addition to providing this novel locking 50
system I have also provided an intermediate
brace or strut which not only has the locking
system incorporated therein, but which also
may be easily removed from the frame or at
tached thereto. The end connections of the brace 55
22 to the frame are identical therefore only one
end connection will be described and like refer
ence characters will apply to like parts on the
other end. Located in the end of the bar is a
transverse open-ended slot 45 which is adapted 60
to ?t over a pin 46, said pin being adapted to
penetrate a bifurcated head of a bolt 41. The
head of the bolt 41 is bifurcated, as stated, form
ing two lugs 48 and 49 between which the ends
of bar 22 are adapted to ?t to allow the open 65
ended slot 45 to ?t over pin 45. The bolt 41
also has a longitudinal bore 50 in the head there
of adjacent the base of the slot in the head.
Disposed within this bore is a spring 5| which
normally presses a ball 52 into a suitable inden 70
tation or cavity 53 formed in the end of the
member 22. When the ball is positioned as shown
in Figure 4 it normally holds the ends of the bar
22 in their proper position and prevents the bar
from becoming loose or from vibrating. The 75
2,108,095
ends of the bar 22 also have beveled surfaces 54
thereon which are adapted to contact the ball
52 when the bar is being inserted between the
members 48 and 49. When this beveled surface
contacts the ball it will force the ball 52 up—
wardly or downwardly, as the case might be, un
til the ball has ridden over into the cavity 53.
The bolts 4'! are secured in the upper and lower
members If! and l I by any suitable means such as
10 wing nuts 55.
It is seen that the bar 22 can be easily removed
from the central portion of the heddle frame after
the bars 25 and 28 have been removed from their
notches. It is only necessary to exert a nominal
15 amount of pressure against the ends of the bar
22 to cause the same to be removed; however
when the heddle bars are disposed within their
respective notches it is almost impossible for the
central bar or strut 22 to be removed since these
20 bars assist the balls 52 in holding the bar in po
sition.
The bars 25 and 28 have suitable heddles 5'!
mounted thereon which heddles have eyelets 58
disposed in the central portion thereof for accom
25 modating strands of the warp in a weaving op
eration.
Figures 6, 7, and 8 show a double heddle frame
similar to Figures 1 to 5 inclusive, with the ex
ception that the upper heddle bars 25 are placed
30 in staggered relation to each other. Likewise
the lower heddle bars 28 are also placed in a stag
gered relation. In a frame of this type instead
of providing members 253, 2! and 22, similar
locking members 60, 6! and 82 are provided in
35 lieu thereof.
On the lower bar H similar lock
ing members 63 and 64 are provided in lieu of
members 26 and 21. The notches in all of these
members are identical to the notches shown in
the corresponding positions in Figures 1 to 4 in
40 clusive, therefore like reference characters will
apply to like notches. The only difference in the
structure of a frame built according to Figures
6, '7 and 8 and the form in Figures 1 to 5 inclu
sive is that the bars 25 and 28 on the right hand
45 side of members 5, ‘I and 8 are disposed at a
slightly lower level from the bars on the left
hand side of the frame.
Figures 9, 10 and 11 show another slightly
modi?ed form which has notches identical to
50 the notches shown in Figures 2, 3 and 4 with the
exception that this is an arrangement for a sin
gle frame instead of a double frame, that is,
only two bars are provided for accommodating
one row of heddles instead of having four bars
for accommodating two rows. In this form the
upper bar Illa has secured thereto locking mem-
bers 10, ‘II and 12 in lieu of the members 20, 2!
and 22 and the lower bar Ila has bars 13 and
14 provided in lieu of bars 26 and 2'! in Figures
2 and 3. Likewise the notches in this form of
the invention are similar to the notches pre
viously described and like reference characters
will apply to similar notches.
In the drawings and speci?cation there has
been set forth a preferred embodiment of the in
vention, and although speci?c terms are em
ployed, they are used in a generic and descrip
tive sense only, and not for purposes of limita
tion, the scope of the invention being set forth
