the Shafts in Looms for Weaving.
I, KONRAD KURMANN, of Lodz, Russian Poland, Manufacturer, do heieby declare the
nature of my said invention and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement :—
The object of my invention is to effect improvements in means and appliances for
attaching heddles to the shafts in looms for weaving.
And in order that my said invention may be particularly described and ascertained,
reference is hereby made to the accompanying drawings, in which similar letters of
reference indicate corresponding parts.
Fig. 1 is an elevation showing a portion of the harness.
Fig. 2 is a section of the attachment device.
Fig. 3 is a perspective view of the underside of the same.
Figs. 4 & 5 illustrate methods of forming heads to the heddles.
a a are the shafts. 6 is one of a pair (or more) of stout wires or rods which hold
the shafts aa at a suitable distance apart. e is the metallic box forming 3 sides of a
rectangle, one side being sufficiently broad for permanent attachment to the shaft a,
as shown, by means of screws, nails, or the like. The opposite parallel side is of
sufficient width to touch, or nearly touch, the edge of the shaft a. Springs fare
introduced between the two parallel sides of the box e, whereby the narrow side is
pressed outwards. C, 2 is another metallic box or rectangular slotted tube, hinged to
the tube or box e at c¹. Each end of the heddles is provided with a suitable
enlargement or head for locking the same under and between the two sides d, d, of the
slotted portion of the tube c. These enlargements or heads of the heddles may be
made in any convenient manner, such as by means of a coil of the wire g; or a small
plate h, passed on to the end of the wire of the heddle, and soldered thereto; either
the coil or the plate being fitted and soldered or brazed at right angles to the heddle;
or by doubling the material forming the heddle and bending the ends outwards, as
shown at m in Fig. 5.
The enlarged ends or heads of the heddles are passed into the slotted tube c, as
shown in Figs. 1 and 2. The action of the springs f is such that they force the narrow
side of the box e against the side c² of the box c, whereby the side c² is pressed
towards the opposite side of the box c thus clenching the heddles between the two
sides of the box c and securing them in any required position relatively to the
shaft a a.
When a heddle becomes damaged and requires removal, the resilient side c² of the
tube c is pressed by hand thus opening the slot and allowing of the removal of the
heddle and a new one being inserted without loss of time..
By this arrangement all kinds of heddles may be employed, the longitudinal slot
being only equal to the diameter of the heddles, which secures the heddles in
position

page_text: 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 improved means and appliances for attaching heddles to the shafts in looms
for weaving, substantially as and for the purposes described.
2. In means and appliances for attaching heddles to the shafts in looms for weav-
ing, the combination of two rectangular metallic tubes or boxes e and c the box e
being secured to the shaft, and the box c hinged to the box e, and caused to operate
by springs f, thereby providing a longitudinal slot, the side c² of which is rendered
resilient by the action of springs f, substantially as for the purposes hereinbefore
described and illustrated by the drawings.
3. The improved formation of the ends or heads of heddles, consisting of soldered
or brazed coils, plates, or equivalent devices substantially as described.
