1, CARL SCHULDER, of Wald, Rhenish Prussia, Germany, Manufacturer, do hereby
declare the nature of this invention to be as follows:
:-
My invention relates to an apparatus which serves to adjust the harness leaves and
harness frames in looms in respect of their length.
The improved apparatus herein described completely replaces the older devices of this
kind, and has, as compared with them, special advantages particularly with regard to
the rapidity of the adjustment but also with regard to the safety with which the con-
nection once effected is secured.
The said apparatus is situated between the harness frames and the strings or
cords to move the latter in order to give the said frames the proper position. In the
working of the loom the said strings or cords will often give way or stretch there-
fore it is necessary at the beginning of the work to adjust the said strings or cords
to their proper lengths.
According to the present invention the harness adjusting device comprises two
flat bars provided at their ends with eyes or links to which are secured the strings
for the leaves or for wires and other drawing devices of the kind known in looms.
One of the said flat bars, hereinafter termed the fixed bar, is provided with teeth
throughout its entire length, upon the side which faces the other bar, the teeth being
of simple rectangular shape, they may however be made triangular or any other
convenient shape. The other bar hereinafter termed the movable bar is likewise
provided on the side which faces the fixed bar with teeth of similar shape so that the
two bars can engage with each other. The said movable bar however is only provided
with teeth for about one fourth part of its length.
At the lower end of the fixed bar is arranged a ring firmly connected with the said
bar or made in one piece with the same, and in which the movable bar can work
freely up and down, but is prevented from moving laterally.
In order to prevent the movable bar from falling through the said ring, a
projection or nose provided on the said bar which projection, when the bar is in
its lowest position relatively to the fixed bar bears against the ring and thus prevents
the said movable bar falling out.

page_text: Upon the fixed bar is loosely arranged a lock or socket the inner sides of which are
slightly tapered. The rear surface of the movable bar is also tapered and the inclina-
tion of this rear surface corresponds with that of the socket. Therefore when the
movable bar engages with the fixed bar and the socket is moved over both bars placed
together, a comparatively firm connection of the three parts is obtained, which will he
firmer according as the taper of the rear surface of the movable bar and the corre-
sponding surface of the socket is reduced.

When the connection is to be severed it is only necessary to push the socket
upwards. The teeth of the two bars can then be disengaged from one another and
secured in another position if desired by again passing the socket over the same.
advantageous, in order to adjust the bars with greater precision to provide the fixed
bar with numbers, which correspond to the teeth of the said bar, so that the teeth of
the movable bar only require to be put in the proper spaces between the teeth of the
fixed bar which is known from the former position of the said teeth in order to obtain
at once the proper adjustment of the leaf.
For further securing the connection of the two bars by the socket, springs can, if
desired, be used for this purpose; a flat spring is secured upon the ring which tends
to press the movable bar away from the fixed bar and therefore, when the connection
is made, exerts a pressure upon the socket, producing friction between the socket and
the bars, which prevents the accidental upward movement of the said socket and the
consequent severing of the connection.
In another modification the same object is attained by providing the socket with a
plate spring which tends to press the two bars together.
In lieu of the plate spring above described an india rubber or spiral spring, or any
other form of spring may be employed.
The above described arrangements enable a rapid adjustment of the two bars rela-
tively to each other and are distinguished by their simplicity and suitableness in the
construction.

1, CARL SCHULDER. of Wald, Rhenish Prussia, Germany, Manufacturer, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:-
My invention relates to an apparatus which serves to adjust the harness leaves and
harness frames in looms in respect of their length.
The improved apparatus herein described completely replaces the older devices of
this kind, and has, as compared with them, special advantages, particularly with regard
to the rapidity of the adjustment, but als with regard to the safety with which the
connection, once effected, is secured.
The said apparatus is situated between the harness frames and the strings or cords
to move the latter in order to give the said frames the proper position. In the
working of the loom the said strings or cords will often give way or stretch; there-
fore it is necessary at the beginning of the work to adjust the said strings or cords to
their proper lengths.
In the accompanying drawing.
Figure 1 shows the apparatus in section when open.
Figure 2 is a similar view showing the apparatus closed.
Figure 3 shows the view of the apparatus as seen from the left hand side of
Figure 2, and,
Figure 4 is a section on the line of Fig. 2.
According to the present invention the harness adjusting device comprises two
flat bars a and b provided at their ends with eyes or links c and d to which are secured
the strings for the leaves or for wires and other drawing devices of the kind known in
looms. The fixed bar a is provided with teeth throughout its entire length, upon the
side which faces the other bar b, the teeth being of simple rectangular shape, they
may however be made triangular or of any other convenient shape. The other
movable bar is likewise provided, on the side which faces the fixed bar a, with teeth
of similar shape, so that the two bars can engage with each other. The said movable
barb, however, is only provided with teeth for about one fourth part of its length.
At the lower end of the fixed bar a is arranged a ring firmly connected with the
said bar or made in one piece with the same, and in which the movable bar b can
work freely up and down, but is prevented from moving laterally.
In order to prevent the movable bar & from falling through the said ring, a projee-
tion or nose e is provided on the said bar, which projection, when the bar bis in its
owest position relatively to the bar a, bears against the ring, and thus prevents the
aid bar & falling out.
Upon the fixed bar a is loosely arranged a lock or socket g the inner sides of which
re slightly tapered. The rear surface of the bar bis also tapered, and the inclina-
tion of this rear surface corresponds with that of the socket. Therefore when the

page_text: bar engages with the fixed bar a and the socket is moved over both bars a, b,
placed together as shown in Figure 2, a comparatively firm connection of the three
parts is obtained which will be firmer according as the taper of the rear surface of
the movable bar and the corresponding surface of the socket is reduced. When
the connection is to be severed, it is only necessary to push the socket upwards. The
teeth of the two bars can then be disengaged from one another and secured in another

in order to adjust the bars with greater precision, to provide the fixed bar a with
numbers as shown in Figure 2, which correspond to the teeth of the said bar, so that
the teeth of the movable bar only require to be put in the proper spaces between the
teeth of the fixed bar which is known from the former position of the said teeth in

connection of the two bars a, b by the socket g, springs can if desired be used.
In Figures 1 to 3 a flat spring k is secured upon the ring which, as shown in
Figure 1, tends to press the movable bar away from the fixed bar a and therefore,
when the connection is made exerts a pressure upon the socket g, producing friction
between the socket and the bars, which prevents the accidental upward movement of
the said socket and the consequent severing of the connection.
The above described arrangement provides a rapid adjustment of the two bars
relatively to each other, which are distinguished by their simplicity and suitableness
in the construction.
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
First. The device substantially as above described for the adjustment of the leaves
and frames in looms, consisting of the toothed bars a and b which can be kept together
by a socket g having conical internal surfaces, substantially as described and represented
in the drawing,
Second. The provision of numbers on bars a or for the purpose of quickly
adjusting the same to any definite length substantially as described and represented in
the drawing.
Third. The arrangement of a spring k for the purpose of forcing apart the bars a
