Improvements in Heddle Frames or Harness for Looms.
I, JULIUS GROB, of Horgen, Canton of Zurich in the Republic of Switzerland,
Manufacturer, do hereby declare the nature of this invention to be as follows:-
The invention consists of an improved heddle-frame or harness in which the
leashes are made of flat metallic blades or bands having their middle part formed
to the shape of an eye as will be hereinafter described, and the ends thereof formed
so as to act as springs against the ends of the adjacent leashes for the purpose of
maintaining the said leashes at a uniform tension throughout the length of each bar
of the frame.
The invention further relates to a new and improved arrangement of those bars
forming the upper and lower part of said frame, and to the adjustment of the end
rods enclosing the leashes to the said bars.
The leashes are made of a metallic blade or band preferably of steel, of suitable
length and provided at both ends with a suitable slot or outcut so as to enable
the said leashes to be slid onto the upper and lower cross-rods which run through
all the leashes of the harness. The said ends of the leashes are moreover bent
in any suitable manner, so that their bent or spring-shaped ends bear against
each other, thus insuring a regular tautness or uniform tightness of the leashes in
the harness.
The said leashes are provided at a suitable height, that is to say at approxi-
mately one half of their length with an eye. The said eye is formed of a slot
of suitable length, made in the blade or band by bending the one half of the
metal in the one direction and the other half in the opposite direction out of
the plane of the band. The edges of the eye being then rounded and smoothened,
the thread passing through the same will be guided with very little friction and the
leashes may be drawn very tight the one to the other without interfering with one
another.
For the purpose of replacing the one or the other of the leashes in the harness
without disconnecting the whole device the upper and lower heads of such a leash
may be cut off and by bending somewhat the whole device such a leash may easily
be removed from the rods and replaced by a new one.
The rods are connected to the hollow bars which are made of a slit tube having
suitable enlargements extending throughout the whole length by means of a suitable
number of supports of bearings formed of two arms placed at right angles the one
to the other, the one arm being of suitable breadth to slide into one of the enlarge-
ments and the other arm being provided with a slot into which slides the rods.
The slotted arm of the support is cut off laterally so as to be capable of engaging
upon the rod without drawing the leashes which might already be arranged upon
the same.
The ends of the hollow bars and of the rods are provided with corresponding
holes through which are inserted pins.
The end bars of the harness are provided with suitable lateral projections which

page_text: engage one of the enlargements. The said end bars are intended to maintain the
leashes at a suitable tension upon the rods and said bars are held together by means
of two or more sliding buckles. When the latter are slid on the bars close to the
rods they will cause the separation of the ends of the said bars and the projection of
those ends will be pressed thereby firmly into the enlargement, the rod being at same
time firmly clasped between the said bars.
To facilitate the lateral spreading of the leashes, if such spreading is necessary in
using the harness, the end bars will preferably be made partly of a chain or of
another suitable connection. For the suspension of the heddle-frame in the loom
there are provided one or more clutches embracing one or more of the enlargements
of the bar and provided with a sliding buckle or ring by means of which said clutch
may be closed or released as desired.
The whole device is preferably nickel plated tinned or galvanized so as to
preserve it from rust.

COMPLETE SPECIFICATION.
Improvements in Heddle Frames or Harness for Looms.
I, JULIUS GROB, of Horgen, Canton of Zurich, in the Republic of Switzerland,
Manufacturer, do hereby declare the nature of this invention and in what manner
the same is to be performed to be particularly described and ascertained in and by
the following statement :-
The invention consists of an improved heddle-frame or harness in which the
leashes are made of flat metallic blades or bands having their middle part formed
to the shape of an eye as will be hereinafter described and the ends thereof formed
so as to act as springs against the ends of the adjacent leashes for the purpose of
maintaining the said leashes at a uniform tension throughout the length of each bar
of the frame.
The invention further relates to a new and improved arrangement of those bars
forming the upper and lower part of said frame, and to the adjustment of the end
rods, enclosing the leashes to the said bars.
In the accompanying drawing I have shown how my said invention may be
conveniently and advantageously carried into practice.
Figure 1 is a perspective view of a loom harness constructed according to my
invention in which some parts are broken away to clearly show the interior devices
and in which two different forms of leashes are shown.
Figure 2 is a front elevation drawn to an enlarged scale, showing how the eyes
are formed in the leashes.
Figure 3 is a side elevation of a series of such leashes drawn to the same scale
as Figure 2.
Figure 4 is a section through the line Y Z of Figure 3.
Figure 5 shows a perspective view of one of the supports.
Figure 6 shows a modified form of the end bars.
The same letters of reference indicate corresponding parts in the several figures
of the drawing.
The leashes A are made of a metallic blade or band preferably of steel, of
suitable length, and provided at one end with suitable mortises, slots, or outcuts a¹,
and at the other end thereof with similar slots a² so as to enable the said leashes to
be slid on to the upper and lower cross-rods B which run through all the leashes of
the harness as shown in Figure 1. The said ends of the leashes A are moreover
bent either as shown at A' and A' Figure 1, or as shown at A3 and A' in the said
Figure 1 or in any other suitable manner, so that their bent or spring-shaped ends

page_text: bear against each other, thus insuring a regular tautness or uniform tightness of the
leashes in the harness.
The said leashes A are provided at a suitable height, that is to say, at
approximately one half of their length with an eye a substantially as shown in.
Figures 2, 3 and 4. The said eye a consists of a slot of suitable length, made in
the blade or band A by bending the one half of the metal as in the one direction.
and the other half a in the opposite direction, out of the plane of the said band.
The edges of the eye a being then rounded and smoothened, the thread X passing.
through the same as shown in Figure 2 will be guided with very little friction and
the leashes may be drawn very tight the one to the other without interfering with
one another as shown in Figures 3 and 4.
For the purpose of replacing the one or the other of the leashes in the harness
without disconnecting the whole device the upper and lower heads of such a leash.
may be cut off at a³ and a Figure 1 and by bending somewhat the whole device
such a leash may easily be removed from the rods B and a new one slid onto the
end of the bar to replace the same.
The rods B are connected to the hollow bars D, which are made of a slit tube
having suitable enlargements d' d' d' extending throughout the whole length, by
means of a suitable number of supports or bearings C (Figure 5) formed of two
arms at right angles to each other, the one arm being of suitable breadth to slide.
into one of the enlargements for instance (d) and the other arm being provided
with a slot c into which the rod B slides. The slotted arm of the support C is cut
away laterally so as to be capable of engaging upon the rod B without withdrawing
the leashes A which may be already arranged upon the same.
The ends of the hollow bars D D and of the rods B are provided with corre-
sponding holes H through which are inserted pins h.
The end bars E of the harness are provided with suitable lateral projections e*
which engage one of the enlargements (for instance d'). The said end bars E as
shown in Figure 1 are intended to maintain the leashes A at a suitable tension
upon the rods B and said bars are held together by means of two or more sliding
buckles e el. When the latter are slid on the bars E close to the rods B they will
cause the separation of the ends of the said bars E and the projections of those
ends will be pressed thereby firmly into the enlargement d', the rod B being at
same time firmly clasped between the said bars E.
To facilitate the lateral spreading of the leashes A if such spreading is necessary
in using the harness, the end bars E will preferably be made as shown in Figure 6,
partly of bars E and partly of a chain E' or other suitable connection. The heddles
being always used in a hanging position the leashes are maintained in tension by
the weight of the lower bar D, to which are affixed their lower ends, their upper
ends being fastened to the upper bar D. For the suspension of the heddle-frame
in the loom there are provided one or more clutches G embracing one or more of
the enlargements d' d' of the bar D and provided with a sliding buckle or ring 9 by
means of which said clutch may be closed or released as desired.
The whole device is preferably nickel plated, tinned or galvanized so as to
preserve it from rust.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:-
1. The herein described heddles A of flat metallic blades formed with slots and
spring shaped ends, the end of oue heddle bearing against the end of the adjacent
heddle substantially as above set forth.
2. In loom harness or heddles the leashes, formed of a flat metallic blade or
and A having a central eye formed of a slot a the sides a and a of which are
bent in opposite directions substantially as shown in the drawings.
3. The combination with the heddles having central eyes, slotted spring-shaped
ends each adapted to bear against the end of the adjacent heddles of bars passing

page_text: through the slots of the heddles, the enclosing metallic tubular bars having
longitudinal ribs and angular supports C for the bars such supports being slotted
and adapted to pass within the enlargement of the tubular bars substantially as
set forth.
4. The combination with the heddles having slots at each end of bars B passing
through the slots the end bars E adapted to receive the bars B and the bands e-
upon the end bar E for clamping the bars B, the enclosing tubular bar D having
longitudinal enlargements into which the ends of the bars E are received
substantially as set forth.
5. The combination with the heddles having slots near their ends and contiguous
springs of the bars B passing through the slots, the supporting pieces C through
which the bars B pass, the tubular bars D having longitudinal ribs and receiving
within them the ends of the heddles, the bars E and their sliding bands e adapted
to pass at opposite sides of the bars B and having outwardly turned ends e for
engaging the longitudinal ribs or elongations of the bars D, substantially as
set forth.
6. The combination with the heddles having central eyes and slotted spring-
shaped ends of the bars B passing through the slots of the heddles, the enclosing
tubular bars D, having longitudinal ribs and the harness clutches G adapted to
grasp the ribs of the bars D, substantially as set forth.
