TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HENRI
ADRIEN BONNEVILLE, of the British and Foreign Patent Offices, 24, Rue du
Mont Thabor, Paris, in the Empire of France, and 38, Porchester Terrace,
Bayswater, in the County of Middlesex, Patent Agent, send greeting.
WHEREAS I am in possession of an Invention for "IMPROVEMENTS IN
APPARATUS FOR THREADING NEEDLES," a communication from Frederick Emile
Texier and Victor Texier, persons residing at Rue de la Roquette, Paris, in
the Empire of France aforesaid, and have petitioned Her Majesty to grant
unto me, my exectors, administrators, and assigns, Her Royal Letters

page_text: Patent for the same, and have made solemn Declaration that it is a
communication. .
NOW KNOW YE, that I, the said Henri Adrien Bonneville, do hereby
declare that the following Complete Specification, under my hand and seal,
fully describes and ascertains the nature of the Invention, and the manner in
which the same is to be performed, that is to say :-
This Invention consists in an improved apparatus, whereby needles may be
threaded automatically. The improved apparatus, seen Fig. 1, is essentially
composed of the following parts :-
Firstly, a rod (o, x,) bored longitudinally at its upper part from o to 0¹,
intended for receiving the needle, which should be placed so that the eye is in
the direction c, t,m. The said rod is also pierced transversally opposite the
eye for the passage of the hook and the thread. The second opening is shown
detached in Fig. 5.
Secondly, of a moveable rod c, t, m, moved by the lever b, s, and moving
horizontally in a right line by means of a groove formed at 6 in the upperend
of the lever; said groove is shown in front view at 1 in Fig. 6. This rod is
guided in its sheath f, u, which hides the movement of the hook.
Thirdly, a hook fixed to the end of the moveable rod c, t, m, intended for
drawing the thread through the transversal opening o, o', of the rod o,r,and
at the same time through the eye of the needle. This hook when at rest
lodges itself in an opening 1, which is formed in the hinder piece y, z, Fig. 7,
and it is engaged in the needle's eye so that this latter remains fixed. The
hook when drawn back by the lever draws the thread with it, and disengages
the needle, which is then withdrawn threaded. It is formed in such a way as
when drawn back to retain the shorter end of the thread, which is more and
more engaged in drawing out the needle up to the moment when the length
being judged sufficient the lever is allowed to fall.
Fourthly, a groover formed between y, c, and o, o¹, to receive the thread,
which will thus be caught during the passage of the hook.
Fifthly,a lever turning on a pivot. p, which is worked by pressing the finger
on the free end s, and which is drawn back to its resting position by a spring
r, s. The upper end of the lever, as has been already remarked, is provided
with a slot, which allows the hook-bearer m, t, c, to move in a right line.
Sixthly, a handle m, for more conveniently holding the instrument.
In Fig. 2, m, c, is the hook-bearer; c, the hook, and m the button, which
terminates its extremity near the lever; Fig. 3 shows the sheath of the hook-
bearer and its support; Fig.4 shows the needle-bearer o, x; the longitudinal
opening o, o¹, where the needle is placed, and the groover, where the thread

page_text: is placed. At the middle of this rod is placed the horizontal support x, p,
which carries the spring r, s, hereafter shown, and the pivot p of the lever.
Fig. 5 shows the same organ in front view, showing the transversal opening
in which the hook and the thread pass; this opening as shown is lengthened
at the upper part. Fig.6 shows a front view of the lever b,s, with the groove
formed at its upper part; Fig.7 shows the hinder part y,z, where is formed.
opposite the eye of the needle a small recess in which the hook enters when
at rest. To make use of the apparatus, the finger is pressed on the ends of
the lever until it is stopped by the handle,and it is retained in that position,
so that the hook is held quite out of the rod o, 0¹, x. The needle is then
placed by the thick end in the opening formed ato in such a way as to touch
the bottom of this opening with the eye turned opposite the hook. The lever
is then allowed to descend gently ander the action of the spring. Its proper
placing is ascertained by the needle being fixed, because in that case the hook
has passed through the eye. The thread is then placed in the groove, and
held quite against the bottom. The finger is again pressed on the lever,and
while holding it the needle is withdrawn. When a sufficient length of thread
has passed through the eye, the lever is allowed to turn over.
Having thus described the nature of the said Invention, what I claim
is the improved construction and arrangement of apparatus for threading
needles, substantially as above described and represented intheaccompanying
Drawings.
In witness whereof, I, the said Henri Adrien Bonneville, have hereunto
set my hand and seal, this Eighth day of November, in the year of
our Lord One thousand eight hundred and sixty-five.
