page_text: PROVISIONAL SPECIFICATION left by Caspar Honegger at the Office
of the Commissioners of Patents, with his Petition, on the 80th
September 1867.
I, CASPAR HONEGGER, of Rüti, Switzerland, Engineer, do hereby declare
the nature of the said Invention for "AN IMPROVED LOOM FOR WEAVING
FIGURED FABRICS," to be as follows:-
The Invention relates to a novel description of power loom for weaving
figured fabrics, and the same consists, lly, in an improved arrangement of
the vertical, wires or hooks of the jacquard apparatus and parts connected
therewith, so as to allow the said hooks to work the shuttles according as
required by the pattern cards.
2ly. In an arrangement for carrying each of the shuttles and according as-
required by the pattern in the position for being acted upon by the picker
or shuttle driver, and for keeping the shuttle boxes in position during each
pick.
3ly. In a peculiar arrangement and combination of parts for causing the
main arbor to procure the working of the batten or lathe, the shuttles, the
jacquard apparatus, and other working parts of the loom.
In the annexed Drawing the Figs. 1 and 2 respectively represent a front
and a sido elevation view of the loom, showing more particularly those parts
that will hereafter be referred to, whilst in both Figures the same letters refer
to corresponding parts.

page_text: A is a lever having its fulcrum in a and worked by the cam b of an arbor B
connected by suitable gearing to the main or driving shaft U; the lever a is
jointed to a rod C carrying a cross bar C for lifting the jacquard hook, wires,
or rods E', E³, E³, E; D is a lever carrying a friction roller d' engaged in a
longitudinal slit provided in each of the rods E', E, E, E; the slit in the
rod of the rod E extending farther down than that in the rod E³; this latter on
its turn farther down than that in the rods E, and so on for each of them in
such manner that the stud pin d' fixed to the lever D will be carried upon
one of the steps f, f, f, f, provided in the arm F of the bell-crank
lever F, G, according to which of the rods E¹, E', E', or E', has been lifted
by the cross bar C, the said rods replacing the ordinary jacquard wires, and
being provided at top in a similar manner as these latter with a hook, and
each of them connected to one of the needles t for being acted upon by the
pattern cards & carried by the cylinder N of the jacquard. The other arm G
of lever F, G, is constantly drawn downward by a spring G¹; the end of the
arm G carries a friction roller g, which may be lifted from underneath by the
inclined tops of the tappets h³, h³, h, respectively fixed at the required heights
to the rods E³, E³, and E, and serving for disengaging the stud pin d³ from
one step of the arm F, and allow it to fall on another step according as
required by the pattern card, and for the purpose of carrying the required
shuttle opposite the picker or shuttle driver, for which purpose also the
lever D carries a hanger I jointed to a rod J acting from underneath against
the shuttle boxes; these latter are allowed to glide up and down in a frame K'
provided in the batten or lathe W, in consequence of which and according to
whether the stud pin d' is lifted upon one or the other of the steps of the
arm F, the corresponding shuttle is carried opposite the picker. U is the
main driving shaft connected by a crank and rod U³ to the batten, and by
means of a pinion to a tooth wheel U*; this latter carrying a pin V₁ and con-
nected by a rod v to a lever frame L turning on a spindle 1, the top of which
lever frame after each pick causes the jacquard cylinder N to turn and
advance one of the pattern cards s. e, e³, e, e', are handles for lifting by
hand, if required, their respective rods E, E, E, E*.
