I, BARTHÉLEMY DONNET, of 23, Passage Menilmontant, Paris, Mechanician,
do hereby declare the nature of the said Invention for "A MOVEABLE SHUTTLE
DISTRIBUTOR APPLICABLE TO FRINGE MACHINERY AND ALSO FOR CERTAIN USEFUL
IMPROVEMENTS IN FRINGE MACHINES," to be as follows:-
The fabrication of fringes, principally for articles of furniture where a
certain variety of colors is required, was heretofore somewhat limited as to the
distribution of the said colors, owing to the necessity of removing certain parts
whenever a different article was to be produced. My Invention obviates
these inconveniences, and it consists, firstly, of a shuttle distributor or thread
feeder, and of a new arrangement of machinery or system of machines to
which the said distributor is particularly applicable.
The first part of my Invention consists of a moveable shuttle distributor or
feeder, the principal features of which are, firstly, the mobility of its shuttles,
which in order to effect the coating of the core and form the "torsade" or
twisted portion are successively displaced almost automatically by the working
parts of the machine; secondly, an arrangement and combination of parts
whereby the same distributor can operate with an indefinite number of

page_text: shuttles, to be increased or diminished at will according to requirements,
without its being necessary to have a special machine for every variety of
fringes. This distributor being the principal part or chief feature of the
machine I will give a special description of it. The said distributor has a
double slide framing in which work the shuttles and ear slides serving to
receive and support them. The shuttles are all placed and arranged over one
another in one side of the frame; they successively escape from the lower part,
so as to reascend on the other side of the said frame, and take their position
again on the upper part. In these various movements each shuttle. is
movable and runs from one square or compartment to the other, carrying
along with it its thread, which on being unwound wraps round the core at the
same time that the loop of the fringe is twisted. These movements of the
shuttle being so far described, I will describe the parts by which they are
operated. The driving shaft is moved either by a crank or other power; this
shaft has on its end a cam actuating spring catches, the office of which is to
maintain the whole of the shuttles on one side of the frame; this cam, by
acting and liberating the said catches, allows the descent of the shuttles, so
that the one last in action can come back and take position on the upper part
of the frame. The shuttles carry on each side a racked gearing with toothed
segmental wheels, intended to make them pass from one frame into the other.
The ear slides serving one to receive the descending shuttles, and the other
to raise up that which has just been in action, may have a variable motion
according to the number of shuttles to be used. The frame is connected to
the machine by cross bars at about one foot distance from the back uprights
forming part of the machine frame. These uprights carry on their upper
part an axis oscillating in bearings actuated by a connecting rod and crank,
which themselves receive their movement from the driving shaft; they cause
the ear slides to move up and down, which takes the shuttle at the lower part
of the frame and causes its ascent to the upper part, at which moment a
toothed segment jointed to a lever and actuated by a stud on the segment
wheel is acting on the lever, causing the shuttle to gear with the wheel and
pass from one side into another, and so forth. The toothed segmental wheels
are set in motion by bevilled pinions keyed on shafts corresponding to the
driving shaft.
The second part of my Invention refers to certain improvements in fringe
machinery. Fringe machines as they have been constructed heretofore are
not so arranged as to work in combination with the new distributor, and
therefore it is necessary to describe the new machine of my Invention, which
differs completely from those heretofore constructed. The bed plate consists

page_text: of a cast-iron plate, on which is fitted the slide which moves up and down, and
upon which also is placed another slide which receives the reel or twister; on
this same slide is situated the twister gear. The drawback motion of the.
slide is caused by means of a cam acting on a lever connected therewith by a
chain. The thread to form the sprig or twisted portion is placed in the.
twisting hook by a batten upon which works the shuttle hook, which at every
time that the said batten moves back comes and passes before the comb takes
up the thread displaced by the distributor (that is to say, that of the ascending
shuttle) and comes back after finishing its course and presents it to the
twisting hook which twists it. The batten works by means of a rod and a lever
acted upon by a cam keyed on one of the back shafts; it is supported by two
rods acting as a double slide. To this batten is fitted the comb which is of
entirely new form; this carries at its lower part an eccentric, whereby it is
caused to take a double stroke previous to its striking the head of the fringe
which permits of the sprig being always twisted straight. The double slide
support bears the fringe head as follows:-One slide carries a spear point which
opens the shed or warp threads for the better laying of the weft threads; this
spear point also serves to support the weft thread when caught in the shuttle
hook. The second horizontal slide moves the spear point forth and back,
whilst the other (the fore one) moves the same to and fro. To the same slide
support is fitted the sprig-pressing pallet, which at the time of twisting presses
on the sprig which is being twisted and prevents the torsion from passing into
the head of the fringe. To a round rod of the same support is fitted a small
stop hook, which prevents the twisting thread from going back. The slide
which carries forward the spear point, the small hook, and the pallet is
actuated by a single cam placed on a transverse shaft beneath the bed plate;
a bevilled pinion keyed upon the shaft (actuating a similar pinion, to which
is connected the cam and pinion bearing box) imparts the movement to all
these parts; this shaft is actuated from the driving shaft by means of two
ellipsoidal pinions. To the heald frames are fitted two weft thread separators;
whenever a frame goes down the separator comes between the weft threads,
so as to only permit the passage of that one which is to be taken by the
shuttle hook and afterwards to be woven. To one of the two pillars (the one
near the driving shaft) is fitted a lever carrying a safety hook for the taking
up of the thread; this lever at each time the shuttle distributor ascends will
be depressed, hook up the passing thread, and hold it stretched, so that the
shuttle hook may not miss it; this lever is actuated from the driving shaft.
The heald frames are driven by a segmental lever, with teeth only at its end,
gearing with a small pinion keyed upon a cross shaft that carries two pulleys

page_text: to which are attached the heald frame straps; this lever is actuated by a cam
which is connected to a wheel gearing with a pinion keyed upon the upper
cross shaft. The fringe when made is drawn by the regulator between two
rollers, and is afterwards wound up round a drum fitted inside the machinė
for that purpose.
