Year: 1869

page_text: LETTERS PATENT to Francois Bujeaud, of Rue du Gond Angouleme,
in the Empire of France, Merchant, for the Invention of "IMPROVE-
MENTS IN APPARATUS FOR MAKING BOTTLE ENVELOPES."
Sealed the 22nd October 1869, and dated the 30th April 1869.
COMPLETE SPECIFICATION filed by the said Francois Bujeaud at the
Office of the Commissioners of Patents, with his Petition and
Declaration, on the 30th April 1869, pursuant to the 9th Section of
the Patent Law Amendment Act, 1852.

page_text: describes and ascertains the nature of my said Invention, and the manner
in which the same is to be performed, reference being had to the Draw-
ing hereto annexed, and forming part of this Specification, and to the
figures and letters marked thereon, that is to say:--
This Invention consists,―
Firstly. In improved apparatus for arranging the straw, cane, rush,
or other analogous material ready to be sewn.
Secondly. In an improved sewing machine for sewing the same.
The straw, cane, rush, or other analogous material of which the bottle
envelopes are to be made is arranged on carriages, and then sewn by
means of the improved sewing machine, having two needles and two
shuttles. When the sewing is effected I remove the sewed straw from
the carriage and form it into a cylinder by tying the free ends of the
sewing threads, and then by tying in one of the ends about an inch
from the extremity I obtain a conical envelope which serves to cover the
bottle.
To make my Invention better understood I will now proceed to describe
it by reference to the accompanying Drawing, in which Figure 1
shews a plan of the apparatus for placing the straw on the carriages;
Figure 2, side clevation; and Figure 3, front elevation of the improved
sewing machine.
The carriages shewn at R, Figure 3, consist of double frames, each of
which is provided with a hinge at a', and a pin fastening at v¹. I press
the straw or other material between the double frames by any suitable
means, but I prefer employing my improved apparatus shewn in
Figure 1. This apparatus consists of a frame 1, 2, 3, 4, on which is
placed at 7, 7, one of the carriages R, shewn at Figure 3, open, that is
to say, with the upper part removed. The material is laid out and an
iron bar 5 is placed in the position shewn in the Figure, then a detent 11
holding back a ratchet 8 is pressed, the spring 9 then causes the axis 10
to turn, and with it a small board 6, by the action of which the straw
is doubled. The carriage is then closed by lowering the upper part,

page_text: which is fixed by means of pins, it is then placed in position, as shewn
at R, Figure 3, it is replaced by an empty one, which is used in the
same manner.
12 is a front view of the ratchet.
In Figures 2 and 3, representing the sewing machine, A, A, A, are
driving pullies; B, the main shaft transmitting motion from the pullies
to the plates C and D; C is the main channelled plate, which by means
of the turning knob N gives motion to the forked piece L to the two
needle carriers M and needles O by means of the cross piece P. In order
that the motion of the forked piece L should not be obstructed, by the
main shaft B an opening is made at the place shewn at u', Figure 3;
D) is a smooth plate, which by means of the knob F of the connecting
rod E connected to the crank G, communicates a to-and-fro movement
to the claws J, and also to the shuttles K, held by the said claws.
Whilst these movements take place the shaft B turns the excentrics X,
and the connecting rods Y and levers m' (Figure 3) furnished with a
ratchet Z give motion to the pulleys T of the shaft V.
The endless
band S, which passes over these pullies is drawn in this movement, by
means of the pins t', it seizes and pushes forward thee carriage R, hold-
ing pressed down the material for making the envelopes, and which is
placed in proportion as it is required. Directly the needles rise the
carriages and the straw would also rise, this is prevented by iron or steel
hoops d', which hold down the straw, whilst the pulley Q pressed by
the spring e' holds down the carriages. At each turn of the plate D
the pin H placed at the end of the connecting rod F strikes the levers n',
through which passes the shaft U, and raises them. These levers are
provided at their extremities with a hook o', which at each turn of the
pulley T engages in a groove o made in this pulley under the action
of the spring p'. In this movement the levers n' raise the hook knives
q' placed under the sewing threads at each side of the carriage. On
the return of the pins H the levers are lowered and the knives are drawn
back cutting the sewed thread; the hook o' leaves the groove o"; this
operation takes place at the end of each carriage, so as to separate them,
otherwise the sewing would unite them all together. is a bobbin
carrying the two threads; k', stretcher pressing each stitch; a', table
on which the machine is placed; 6', framework of the machine; c', support
of the shaft I; f¹, slide piece for guiding the band S and carriages R,
and to which are fixed the circular guides g' of the shuttles; h', supports
of the shaft U; i¹, support of the shaft V; j', support of the lower pulley

pin s'
The sewing being effected at both ends of the blades of straw or other
material the carriages are raised and opened, the sheet formed is drawn
out, rolled, united, and pressed, as herein-before described for finishing
the envelope and to make it ready for packing bottles.
Having now described the nature of my Invention, and the manner
of performing the same, I do not confine myself to the precise details of
construction herein laid down and shewn in the Drawing, but what I
claim is,
First. The arrangement or construction of an apparatus for arranging
the straw, as herein-before described and shewn in Figure 1 of the accom-
panying Drawing.
Secondly. The employment of the carriages R placed one behind the
other on a moveable endless band S, which draws them along, so as to
make them pass before the two needles o, serving to sew the the blades
of grass or other material together by means of two threads as herein-
before described and shewn in Figures 2 and 3 of the accompanying
Drawing.
Thirdly. The combination of the connecting rod E, pin H, levers n',
spring p', knives q³, hook o¹, and pulley T, with groove o", for obtain-
ing the mechanical separation of the carriages when sewn together, as
herein-before described and shewn in Figures 2 and 3 of the accompany-
ing Drawing.
Fourthly. The combination of the known or new parts forming the
improved machine applicable to making bottle envelopes, as herein-
before described and shewn in Figures 2 and 3 of the accompanying
Drawing.
In witness whereof, I, the said Francois Bujeaud, have hereto set
my hand and seal, this Twenty-second day of April, in the year
of our Lord One thousand eight hundred and sixty-nine.
F. BUJEAUD. (L.S.)
