Improvements in Comber Boards for Jacquard Mechanism.
I, ADOLF BRAUCH, of 45 West Street, in the City of Paterson, County of
Passaic, and State of New Jersey, U.S.A., Gentleman, 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 object of my present invention is to provide an adjustable sectional comber
board for Jacquard harness by means of which any number of patterns-or the
same pattern in different sizes and of different width can be woven, without the
necessity of changing the harness and the comber board, and thus greatly
simplifying the work and reducing the time for changing over to different designs
and patterns.
The invention consists in the improved adjustable sectional comber board, its
adjusting and locking or tightening mechanism, and in the combination and
arrangement of the various parts thereof, substantially as will be hereinafter more
fully described and finally embodied in the clauses of the claims.
In the accompanying drawings
Fig. 1 is a perspective view of my improved comber board, in connection with a
series of harness threads, and Fig. 2 a front elevation of Fig. 1, and illustrating the
comber board adjusted for the same pattern, but, of a different size.
In said drawings A represents a rectangular frame, consisting of the parallel
sectional side bars a, a 0 and b, 60, hinged or otherwise foldingly connected together
as at a 2 and 62 respectively, and of the conecting braces c, c, preferably arranged
at or near the outer ends of said sectional side bars, which latter are provided on
their inner sides with longitudinally extending grooves, a 1 and 61, as clearly shown
in Fig. 1.
One of the side bars, in the drawings b, 60, is provided on its outside and at or
near its hinges with the headed studs or screws e e, which latter penetrate, and are
engaged by and in frictional contact with the elongated spring wire loop e 2, by
means of which latter, the sections of the frame are held in adjusted and normal
position, as will be manifest.
In the grooves a 1 and 61 is arranged the comber board proper, consisting of a
series of two or more sections d, d1, d 3.and d 4, connected together by threadsid 5
or in any other desired manner and which boards are held in a fixed position by
means, such as pins m, m 1, as will be manifest.
The harness threads h, h1, h2, h3, ...... pass through the openings in the
comber board in the well known manner.
As shown in the drawings the center line of the hinge is above the face of the
comber board, but it is evident, that it may be placed in the plane of the face of
the said comber board, so as to avoid the sliding of the said board within the
groove of the frame, during the adjustment; in this case the frame may also be
dispensed with, and the hinge directly arranged upon the central sections of the
comber board.
Whenever a certain pattern is completed, and a different pattern is desired,
calling for a different.number of harness threads to the inch, the frame, containing
the comber board, or the latter one-if no frame is used, is swung upon its pivot
until the proper adjustment is obtained; the spring loop e 2, being in frictional
contact with the headed pins e, e 1, will hold' the sections in adjusted positions.

page_text: It is evident, that other means for tightening and locking the sections in
adjusted position may be employed without departing from the spirit of my
invention, such as for instance, is used in setting dividers, compasses, etc.:-in
place of the pins m, m 1, clamps or other suitable devices may be used.
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. A folding sectional comber board, provided with means for adjusting and
locking its sections at any desired angle, substantially as and for the purposes
described.
2. A comber board consisting of a folding frame, a series of two or more
perforated sections arranged in said frame and means for adjusting and locking the
sections, of the frame at any desired angle, substantially as and for the purposes
described.
3. A comber hoard, consisting of a frame-made in two parts.hinged or otherwise
foldingly connected, a perforated board arranged in said frame, and means for
adjusting and holding the sections of the frame at any desired angle, and means
for securing the comber board to the frame, substantially as and for the purposes
described.
