A Communication to me from abroad by Clément Guy, of Paris, France,
As will be seen on reference to the accompanying Sheet of Drawing, the needle
of the Sewing Machine works in the piece a, and that the bobbin A is placed upon
a sleeve d concentric with the needle-bar and having a plate or flange c upon which
the bubbin A rests. The sleeve d is held by a collar b, screwed on the inner tube
or bush. A thread carrier h, attached to the plate or flange c receives the thread
from the bubbin, and tension is given thereto by the guide thread m.
Rotation is given to the bobbin A and to h, by means of the pulley n and
band B which passes over the pulleys D and E, this latter being fixed on the main
shaft of the machine. The thread from the bubbin A is thus wound round the
needle at each stitch of this latter and an ornamental seam thereby produced.

WILLIAM EDWARD GEDGE, of N° 11 Wellington Street, Strand, London, in the
County of Middlesex, Patent Agent, "IMPROVEMENTS IN SEWING MACHINES"
A Communication to me from abroad by Clément Guy, of Paris, France,
This Invention relates to improvements in Sewing Machines, and Figures 1
and 2 of the accompanying Sheet of Drawing show parts of a sewing machine
embodying them :-
Figure 1. being a front view partly in section and
Figure 2. a side elevation of samo
As will be seen on reference to the Drawing:-the needle of the sewing machino
works in the piece or presser tube (" onglette") a, (see Figure 1) and that the
bobbin or spool A, is placed upon a sleeve, coupling box or clutch d, concentric
with the needle bar and having a plate or flange c, upon which the bobbin A, rests.
The sleeve is held by a collar or nut b, screwed on the inner tube or bush.
A thread carrier or threader h is attached to the plate or flange c, and receives the
thread from the bobbin, by means of a guide thread m, which also serves to give
tonsion to the thread.
Rotation is given to the bobbin A, and to the thread carrier h by means of the
pulley n and of the band B, which passes over the pulleys or gearing D and E, this
latter being fixed on the main shaft M of the machine.
The thread from the bobbin A, is thus wound round the needle at each stitch of
this latter and produces an ornamental seam.
If the band B, should slacken it may be tightened by means of the screw G,.
A chain may be used instead of a band.
By unscrewing the screw G, the band B is slackened, the rotation of the thread
carrier, is arrested and the machine makes a chain stitch.
Having now described and ascertained the nature of the invention communicated
to ine as aforesaid and in what manner the same is or may be performed.
I Claim as secured to me by the hereinbefore in part recited Letters Patent :-
Firstly In a sewing machine, a bobbin or spool turning centrally upon a tube
in which works the presser tube or piece a, and the needle substantially as
described.
:
Secondly In a sewing machine, a bobbin which turns on a sleevo, clutch or
coupling box having a groove or pulley and actuated by the main shaft of the
machine by incans of a band or of a chain B, substantially as described.
Thirdly: In a sewing machine, the screw O, in combination with the pulley D,
to give tension to the band or to arrest the rotation of the thread carrier h, sub-
stantially as described.
In Witness whereof I the said William Edward Gedge have hereunto set my
hand and seal this Twenty Eighth day of June in the year of our Lord
one thousand eight hundred and Eighty three
