Improvements in Looms for Weaving Ribands and other similar
Fabrics
I AUGUSTO CESAR DA CUNHA MORAES of 48 rue de Bondy Paris in the Republic
of France Engineer 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
-
This Invention of improvements in looms for weaving ribands and other similar
fabrics consists essentially in an improved method and arrangement of mechanism for
operating the shuttles as hereinafter described In a riband loom for example arranged
according to this invention the shuttle box is independent of the lay or batten in
place of being caused to follow the oscillating movements of the latter as in ordinary
fooms of this description
And in order that my said Invention may be fully understood I shall now proceed
more particularly to describe the same and for that purpose shall refer to the several
figures on the annexed sheet of drawings the same letters of reference indicating
corresponding parts in all the figures
Figure 1 of the accompanying drawings represents in front elevation such of the
parts of a riband loom for example as are necessary to explain this invention and
figure 2 represents a transverse section of the same the section being taken along the
line A B figure 1
In this loom the shuttle box marked M in the drawing is separate from the lays or
battens two of which are shown at P P and which oscillate in the usual manner upon

page_text: a shaft O The shuttle box M is fixed to the frame and carries shuttles L which
simply partake of a to and fro motion transversely to the warp in place of the usual
compound motion
This to and fro or reciprocating motion is imparted to the shuttles by a bar or
shuttle driver C which is caused to slide or reciprocate in the direction of its length by
any suitable arrangement of mechanism and drives the shuttles by means of pins e e¹
which engage with corresponding holes at or near the two ends of each shuttle
These pins are capable of sliding vertically in the shuttle driver and are provided at
their lower extremities with anti friction rollersf working in a stationary cam groove
or guide ? This groove bends downwards under each batten P as indicated in the
drawing the curve or incline of the groove at these points being so regulated as to
enable the groove to pull down the pins and cause them to leave the forward ends of
the shuttles at the moment when the latter enter the shed as indicated in the case of
the left hand shuttle in Figure 1 and in the section Figure 2 At the moment when
the pin e³ for example is about to be disengaged from the front end of the shuttle the
pine is raised by the action of the groove and engages with the hole in the hinder
end of the shuttle so that the latter continues its movement without interruption
like manner when the pine is depressed the pin e³ is raised so that the shuttles are
always operated by one or the other of the two corresponding pins carried by the
shuttle driver C The other parts of the loom may be constructed and operate in any
ordinary or suitable manner the battens P being operated by the shaft O for example
and the shuttle driver C receiving motion from any suitable arrangement of levers,
cams or the like
In
Having now particularly described and ascertained the nature of the said Inven-
tion and in what manner the same is to be performed I declare that what I
claim 18
-
1st In a loom for weaving ribands and other similar fabrics the improved arrange-
ment whereby the lays or battens are made separate from or independent of the
shuttle box and the latter is enabled to be made fixed or stationary substantially as
herein before described with reference to the accompanying drawings
2nd A loom for weaving ribands and other similar fabrics provided with a stationary
shuttle box in which the shuttles have a reciprocating motion imparted to them by
means of a driver and pins the said pins being alternately drawn down or out of
action and elevated or brought into action substantially as hereinbefore described with
reference to the accompanying drawings
