page_text: I JAMES YATE JOHNSON of 47 Lincoln's Inn Fields in the County of Middlesex
Gentleman do hereby declare the nature of this Invention which has been commu-
nicated to me from abroad by Augusto Cesar da Cunha Moraes of 48 rue de Bondy
Paris in the Republic of France Engineer 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 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 looms of this
description.
And in order that the 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 both 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 loow 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
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 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 e
which engage with corresponding holes at or near the two ends of each shuttle. These

page_text: pins are capable of sliding vertically in the shuttle driver and are provided at their
lower extremities with anti friction rollers f 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 tho 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 e² for example is about to be disengaged from the front end of the shuttle the
pin e is raised by the action of the groove i and engages with the hole in the hinder
end of the shuttle so that the latter continues its movement without interruption. In
like manner when the pin e¹ is depressed the pin e2 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 receiving motion from any suitable arrangement of lovers
cams or the like.
Having now particularly described and ascertained the nature of this Inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
First In a loom for weaving ribands and other similar fabrics the improved
arrangement whereby the lays or battens are made separate from or independent of
tho shuttle box and the latter is enabled to be made fixed or stationary substantially as
hereinbefore described with reference to the accompanying drawings.
Second: A loom for weaving riband 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.
