TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HENRI

of Middlesex, Patent Agent, send greeting.

page_text: WHEREAS I am in possession of an Invention for “CERTAIN NEW AND
USEFUL IMPROVEMENTS IN MACHINES FOR SPINNING WOOL, COTTON, SILK, and
FIBROUS MATERIAL IN GENERAL," communicated to me by Celestin Martin,
a person resident at Verviers, in the Kingdom of Belgium, and have
petitioned Her Majesty to grant unto me, my executors, administrators,
and assigns, Her Royal Letters Patent for the same, and 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; reference being had
to the accompanying Drawings, and to the figures and letters marked
thereon, that is to say :-
The Invention relates to certain new and useful improvement in the
construction of fixed machines for spinning wool, cotton, silk, and
fibrous material in general, patented December 4th, 1872, numbered
3653, and January 16th, 1873, numbered 174, and consists in applying
a new and useful apparatus to fixed spinning machines represented in
the accompanying Drawings, in which Fig. I. is a sectional cross
elevation of a fixed spinning machine constructed with the improved
part, and Fig. II. and III. front views of parts constituting the
Invention.
This improvement consists in the application of the cylinders A, in
which are formed as many grooves B as there are threads in the machine.
These grooves B are always placed in the same direction as the threads,
or rather the threads are placed in each groove, but in different positions,
according to the twist of each thread and the height of the regulating
balance picce; thus the balance piece C¹ is shown in the annexed
Drawing at its greatest height, and consequently prevents the thread
from falling to the bottom of the groove of the cylinder A, while the
balance piece C², under the pressure of. a greater tension of the thread
produced by the too great twist it has received, has lowered as far as to
allow the thread to fall into the bottom of the groove. In this position
in consequence of the very acute angle of the grooves in the cylinders A.
the twist given to the thread by the tube D is stopped, or rather
instantaneously diminished, because the thread is pinched at the bottoni
of the said groove. The rotary speed imparted to the cylinders A being

page_text: more accelerated than the rotary movement of the drawing cylinders E,
the cylinders A provided with acute angled grooves have the further
advantage of lessening the tension of the thread between them and the
said cylinders E whenever this tension is increased in consequence of too
great twist given to the thread by the tube D.
Having thus described the nature of the said improvement, and the
manner of carrying it into effect, I claim and wish to secure by Royal
Letters Patent,—
1tly. The system of fixed spinning machine, substantially as above
described and represented in the annexed Drawings.
2dly. In the fixed spinning machines the grooved cylinders A in
combination with the regulating balance pieces C¹ and C³ and tubes D,
operating substantially as and for the purpose shewn and described.
In witness whereof, I, Henri Adrien Bonneville, have hereto set
my hand and seal, this Fourth day of July, in the year of our
Lord One thousand eight hundred and seventy-four.
