ATOMIZER OR DISPERSING DEVICE Filed March 5, 1937 INVENTOR ATTORNEY Patented June 6, 1939 UNITED STATES PATENT. OFFICE ATOMIZER OR DISPERSING DEVICE Application March 5, 1937, Serial No. 129,126

1 Claim.

This invention relates to improvements in atomizing or dispersing devices.

The object of the devices forming the subject matter of this invention is the provision of a device for, by atomizing or dispersing in the most uniform and highest degree of fineness, bodies and substances which, before the atomization or dispersion, are in a liquid, pulverulent or gaseous condition, and thus to obtain an efficiency m in the practical working that has hitherto been unattained.

Another object of the invention is the provision of an atomizer or diffuser of the fuel for driving an engine, preferably internal combus- 15 tion engine, in which the dispersion of the fuel is effected by means of a wire spiral in which a perforated tube is inserted which is adjustably attached to the stem of the atomizer body, and with which a screw cap co-operates for regulat- 20 ing the distance between the individual convolutions of the spring, and thus the fineness of the atomized fuel spray besides acting as a fuel filter.

These and other objects and advantages of the invention will become more fully apparent as the description thereof proceeds and will then be more fully defined in the appended claim.

The single figure in the drawing shows a longitudinal section through a device equipped with 30 a cylindrical atomizer, constructed according to my invention.

The atomizer may, naturally, also be directly connected-i. e., without the aid of a stem of the device-with a nozzle or a part from which one 35 of the said bodies or substances issues. As a matter of fact, the drawing represents only the preferred form of employment or construction.

The part it inthe drawing is the one that is either made in one piece with the so-called nozzle or is the body of the device or is the part which is connected with the nozzle by means of any desired fastening means and from which the said bodies or substances which are to be atomized or dispersed pass into the inner space of the atomizer.

The part 1 is the atomizer itself.

The part h serves to hold the atomizer to the body of the device or to its hollow shank if such is employed.

In the cases in which the atomizer consists of a spiral other than a flat one, the part it serves at the same time also for the required accurate and fine adjustment of the intervals between the 55 individual helices of the wire spiral, which in-' tervals alone effect the atomization or dispersion.

The atomizing or dispersing operation of the body or substance to be atomized is essentially always as follows:

The body or substance to be atomized or dispersed passes through the aperture or apertures b into the bore or space 0 of the body (2 of the device and then through the aperture or apertures e in the shank of the body 11 of the device to the atomizing apertures g-in the case of a wire spiral, to the intervals g between the helices of the spiral f of the atomizer-and here it undergoes its atomization or dispersion, issues from the atomizer and then mixes most uniformly 15 and intimately with the substance (e. g., air, steam, etc.) which is outside the device or is passing by the atomizer, or combines with the particular substance in question.

As compared with the known devices, the devices according to the invention possess briefly summarized, the following advantages with regard to the degree of fineness and the uniformity in the atomization or dispersion actually to be obtained with them:

The body or substance to be atomized or dispersed can issue from the body of the device or atomizer through the apertures intended for the fine atomization or fine dispersion.

The atomization or dispersion is effected by the atomizer along-i. e., only through the intervals themselves between the individual helices of the wire spiraland the atomization or dispersion is therefore independent of a screwthread around the shell of the body of the device and of a wire Wound into this screw-threadi. e., it is in no way dependent upon an exact gauging of the internal diameter of the wire spiral to the diameter of an atomizing member or to the body of the device.

Any desired degree of fineness in the atomization or dispersion can be adjusted in an extremely simple manner in one and the same atomizer.

A hitherto unobtained fineness and uniformity in the atomization or dispersion.

Its utility in all cases in which uniform and even greatest fineness is necessary or desired in the atomization or dispersion of the said bodies or substances.

Undisturbed working.

Easily to be taken apart, the possibility of cleaning and putting it together by any layman.

Greatest indestructibility when in use, even in the hands of laymen.

10 openings in said body and the interstices between the individual convolutions of said spring serving as atomizing agents, said perforated tube adjustably secured to said stem and a screw cap on said. body acting as agents for regulating the distance between the individual convolutions of the spring acting as atomizer openings for regulating the fineness of the atomized fuel spray.
