APPARATUS FOR TRANSFORMING LIQUTDS INTO A. MIST.

Application filed February 24, 1923. Serial No. 621,104.

T 0 all whom it may concern:

Be it known that I, ENnIoo GARDA, of 68 Rue Reaumur, Paris. France, have invented Apparatus for Transforming Liquids into a Mist, of which the following is a full,"clear, and exact description. 0

The present invention has for its object anapparatus for transforming into a mlst, by means of a compressed fluid, llqulds of any composition and density. TlllS apparatus is essentially characterized by the fact that the fluid under pressure, compressed air for instance, adapted to drive the liquid to be pulverized through the apparatus, escapes from the latter through nozzles of any suitable shape and cross section for ensuring its distribution and its exit about the apparatus. This result is atta ned by imparting to the said fluid, successlve impulses producing at the outlet of these nozzles, a vibratory and whirling field, composed of the liquid divided in multiple jets. As this liquid is thus driven outside the apparatus, it is violently projected, broken and transformed into a mist the particles of which, owin to the friction to which they are subjected, acquire an electric charge of the same sign, repel each other and create an 1mpalpable and dry mist which, accordlng to the liquids employed, is applicable to medicine, hygiene or industry.

The apparatus forming the subject-matter of the present invention is essentially constituted by the combination:

(a) Of a central core so shaped as to present, midway of its height, a cylmdrlcal swelling above and below which respectively open apertures communicating the upper ones, with a compressed fluid inlet conduit, the lower ones with an inlet conduit for the liquid to be pulverized;

(6) Of a tubular body connected to the compressed fluid inlet conduit and enclos ng the upper part of the central core on WlllCll it is secured. this tubular body terminating at its base by a crown, resting on the upper face of the cylindrical swelling of the central core, and being provided with notches which form nozzles adapted to ensure the escape about the apparatus of the compressed fluid conveyed by, the conduit and the 11 per orifices of the central core 1nto a chamber formed between the latter and the tubular body which covers it;

(0) Of a second tubular body connected, at its lower part, to the inlet conduit for the liquid to be pulverized, and enclosing the lower part of the central core on which it is mounted so as to be capable of being moved longitudinally and adjusted in position, this second tubular body being provided, on its upper edge, with an inner circular groove in which the swelling of the central core fits with a slight play so as to form a passage of adjustable cross section permitting the lssue of the liquid which, drawn by the fluid under pressure in a chamber formed between the central core and the second tubular body, is emusified with the said compressed fluid which, at the same time, enters in combination with the liquid for forming an impalpable and dry mist.

In order that the invention may be clearly understood, a form of construction of the improved pulverizing apparatus will be described hereafter with reference to the accompanying drawing in which:

Fig. 1- is a front elevation.

Fig. 2 is a vertical section.

Fig. 3 shows the central core in front elevation.

Figs. 4 and 5 respectivel illustrate in vertical section the upper an lower tubular bodies.

Fig. 6 is a perspective View of the index..

As. illustrated in the accompanying drawing, the apparatus in accordance with the invention comprises a core which, turned off as shown in Fig. 3, is provided, midway of its height, with a cylindrical swelling or enlargement 1 the opposite faces of which are respectivel connected by conical surfaces to two cylin rical parts 2 and 3 perforated with orifices respectively opening into longitudinal channels 6 and 7 drilled in the axis of the central core and which do not communicate together, as clearly shown in Fig. 3.

This core terminates, at its ends by two threaded parts 8 and 9 which are respectively adapted to receive by screwing the upper tubular body 10 and the lower tubular body 11 which are respectively connected to the inlet pipe for a fluid under pressure, compressed air for instance, and to a vessel containing the liquid to be ulverized.

The upper body 10, whlch is shaped in such a manner as to enclose the upper part of the central core, fits with a slight friction on a cylindrical part 12 of the latter and terminates, at its base, in a crown resting on the upper face of the enlargement 1 of the said central core and provided, on

lit)

its periphery, with notches 13 adapted to form distinct nozzles permitting the regular escape all round and outside the ap aratus, of the fluid under ressure (air or t e like) conveyed by the c annel 6 and openings 4 into the circular chamber 14 formed at the base of the body 10.

The upper body 10 1S alsoprovided at its base with a flange 15 in which is formed a circular groove 16 ada ted, as will be explained, to create ed ies in the product transformed into a mist.

The lower body 11 fits and is also guided with a slight friction on a cylindrical part 17 of the central core which it encloses, at

its lower part, beyond which it is connected,

by a suitable conduit, to a vessel containing the liquid to be transformed into a mist.

This tubular body 11 terminates at its upper part by a crown 18 in which is formed a circular groove 19 ada ted to form a housing for the cylindrica enlargement 1 of the central core.

This enlargement 1 fits in the groove 19 with a certain play which as clearly shown in Fig. 2 forms a passage permitting the escape to the exterior of the a paratus of the liquid to be ulverized, sue ed, by the flow of the flui under pressure through the notches 13, into the chamber 20 formed in the body 11 and conveyed in the said chamber through the channel 7 and the openings 5 of the said central core.

From the foregoing it will be understood that the fluid under pressure is subjected, during its passage through the notches 13, to a rollin which determines successive impulses of the said fiuid and the creation at the outlet of the notches of a vibratory and whirling field which reduces the drawing along of the liquid film issuing from the groove 19 and that the said liquid film is drawn along, then violently projected outside the apparatus, the said film whirling in the groove 16 and being broken into a mist the particles of which, owing to the energetic friction to which they are subjected, are charged with electricity of the same si 11 and rep'el each other forming an absolute y impalpable and dry mist.

In order to allow of varying the proportions of the liquid drawn along by the escape of the compressed fluid, the lower tubular body 11 is mounted on the central core so that it can be longitudinally displaced on the latter for adjustin at will the section of the passage formed etween the enlargement 1 and the roove 19.

In the examp e shown, the tubular body 11 is provided with an inclined slide 21. A screw 22 is secured to the central core and extends through the slide 21, said screw being provided with a nut at 23 and an index 24, said index being loosely mounted upon the screw whereby the value of the angular displacement of the tubular body 11 on the threaded part 9 may be determined and the latter (placed at any desired position as indicate by a suitable graduation 25 of said tubular body. In order to prevent the rotation of the index upon the screw when the nut 23 is adjusted said index is provided with a boss 24", the flat sides of which engage the inclined walls of the slide 21.

The above described arrangements are, of course, given by way of example only, the forms, materials and dimensions of the constituent parts can be modified without departing thereby from the principle of the invention.
