I ARMAND PETIT, of Fourmios, in the Republic of France, Engineer do hereby
declare the nature of my invention and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement and
accompanying drawings (that is to say)
In all spinning mills and particularly in those for spinning wool, the conversion
into threads of the slivers or yarns previously prepared, is only properly effected
when the air in the room contains a certain degree of moisture.
In winter this moistening of the air is easily effected by means of steam brought
from the boilers and allowed to escape through small cocks or valves placed at
suitable distances apart upon a pipe running through the mill. This pipe serves at
the same time for heating the rooms but it cannot be made use of in summer.
Morcover it has the serious objection that it uses a large quantity of steam from
the boilers of the mill.
These considerations have given rise to various contrivances which fulfil more or
less satisfactorily the desired ond-the moistening of spinning rooms,—but they all
have the objection that they are very expensive, in first cost, so that many manu-
facturers decline to adopt them.
By my invention the required amount of moisture in rooms in which spinning is
carried on is very easily obtained at an exceedingly small first outlay and with an
expenditure of motive power practically nil.
The accompanying drawing is in illustration of my improved moistening apparatus
by means of which I have obtained results superior to those given by any other
system.
Figure 1 is a vertical section through the apparatus fixed upon a column. Figures 2
and are horizontal sections shewing the arrangement of the revolving vanes F
and G hereinafter described. Figures 4 and 5 shew the angle of inclination of the
same vanes F and G.
.
The apparatus is placed in the upper part of the rooms in different positions and
is fixed either to the columns or to the beams of the ceiling. Each apparatus is
composed of a vertical shaft or axle A supported below by a footstep B and above
by a bearing C. Above the latter bearing is fixed a grooved pulley D which is
driven by means of a small cord and itself drives the next succeeding apparatus by

page_text: means of a second cord, the amount of motive power being as will be seen very
small. The shaft A makes about twelve hundred revolutions per minute and has
fixed upon it at Ga vane having six arms or blades inclined at an angle of about 45°
serving to draw in the dry air from the room whilst at F is fixed a second vane
having four arms or blades, preferably of metal like those first described but inclined
at an angle of about 10° only, which serves to moderate the upward current of air.
At E is fixed a helically formed brush which allows the air to readily continue its
upward movement.
At K is a cock or valve through which a small stream of cold water is allowed
continually to pass, the falling stream being pulverized or atomized by the brush E,
so that the air from the vanes G and F can readily absorb it in its upward progress
and leaves the top of the apparatus sufficiently saturated with inoisture the degree of
saturation being casily regulated by the amount of opening of the cock K.
The surplus water falls into the basin H whence it escapes through a pipe at L.
In order to prevent the water from being scattered about by the speed of revolution
of the shaft A, the vanes and the helical brush are surrounded by a casing or envelope
of sufficiently fine woollen cloth which extends round the circumference of the
apparatus from I to J and through which the air charged with moisture passes as
well as out at the top. The combination of this envelope with the rest of the
apparatus forms an important part of my invention.
By the use of the apparatus described and shown, I have obtained excellent results
in my own establishment.
The improved apparatus may also be used for hygeinic purposes particularly for
the aëration and ventilation of inhabited places, hospitals, ships and the like. There
may be added at the top of the shaft A as shown in the drawing a small vessel N
containing any suitable antiseptic or perfumed liquid, which is scattered upon the
brush through a narrow passage M and opening O formed in the interior of the
shaft A. The moistened air becomes thus mixed with the contents of the vessel M.
The invention is applicable to all cases in which it is required that air should be
moistened.
I do not confine myself to the precise form, arrangement, and materials of the
apparatus, which may be varied more or less as desired, but having now particularly
described and ascertained the nature of my said invention and in what manner the
same is to be performed, I declare that what I claim is :-
1. The combination of the vertical shaft revolving at a sufficient speed with tho
surrounding permeable envelope and the two sets of inclined vanes, substantially as
and for the purpose described and shewn.
2. The helical brush fixed upon the vertical revolving axis, and serving to pulverize
or atomize water introduced upon it from above, substantially as and for the purpose
described and shewn.
3. The cloth casing or envelope partially surrounding the apparatus, as shewn in
the drawing, so that instead of vapour only air saturated with water is allowed to
escape, such saturated air possessing the advantage of not rusting metals.
