To aZZ whom, it may concern:

Be it known that I, EMIL HEINRICH GON- RAD OEHLMANN, of the city of Berlin, in the Empire of Germany, have invented certain new and useful Improvements in Air Moistening and Ventilating Apparatus, (for which I have obtained Letters Patent in Germany, No. 44,744, dated July 17, 1888; in Switzerland, No. 56, dated January 21, 1889; in Aus- 10 tria-Hungary,No. 50,479 and No. 11,346, dated June 1, 1888; in France, No.187,976, dated March 20, 1888; in Belgium, No. 80,166, dated January 31, 1888; in Italy, No. 22,899/462, dated May 8, 1888; in Great Britain,No.17,852, [5 dated December 28, 1887; in Spain, No. 7,787, dated April 80, 1888, and in Luxemburg, No. 982, dated April 24, 1888,) of which the following is a specification.

In ord r to moisten the air, as required in spinning-mills, very fine sprays of water projected from several nozzles are caused to impinge against suitable surfaces, and the fine cloud of water particles thus obtained is introduced along with the air from the vcnti- 2 5 later into the \vorlcrooms.

The apparatus hitherto used have serious disadvantages both in the heavy construction of the spraying device and also in the connection of the latter with the ventilating o apparatus. The light and speedy cleaning of the nozzles, which should be'the casein practice, is not effected, nor is the proper degree of moisture imparted to the air, so that the machinery and other objects in the work- 3 5 room shall be maintained in an effective state of moisture. All these disadvantages are avoided by the central air-moistening apparatus forming the object of the present invention and in such a manner that, first, any

40 number whatever of nozzle-openings are so united together that the whole of these nozles is easily accessible and can be cleaned in a short time by brushing them after the lid of the nozzles has been removed, whereas 5 formerly each nozzle had to be cleaned singly by means of a fine needle after the spraying apparatus had been screwed off; secondly, only the finest spray of water is introduced into the air from the ventilator, for the full current of the latter does not meet the cloud of fine water produced and does not carry away fine and coarse water-spray together and indiscriminately, as has hitherto been the case, but acts upon the dispersed water only partially and with lessened force, so that 5 5 the air only carries away the finest water particles, while the coarser onessink down, owing to their gravity,and are collected in a suitable reservoir, and, lastly, it must also be noticed that by reducing the number of noz- 6o zles not only an essential simplification of the apparatus is obtained, but that by the suppression of the cooks that were hitherto necessary a great saving of cost is also effected. 6 5

The invention consists in the construction and combination of parts and details, as will be fully described and set forth hereinafter, and then pointed out in the claims.

In the accompanying drawings, Figure 1 is a vertical transverse sectional view of my improved spraying-nozzle. Fig. 2 is a plan view of the same, the cover being removed. Fig. 3 is a vertical transverse section of a modification of the nozzle. Fig. 4 is an enlarged detail side view of parts of the same, parts being broken out and others being in section. Fig. 5 is a vertical transverse sectional view of the air-moistening apparatus provided with myimproved nozzle. Fig.6 is a similar view of a modification of my improved moistening apparatus and nozzle. Fig. 7 is a cross-sectional viewof a modification of myimproved spraying-nozzle. Fig. 8 is a plan view of same, the corner being removed. 8 5

Similar letters of reference indicate corresponding parts.

On the body A of the nozzle, Fig. l, which is connected with the pipe A, bringing the water, is screwed the upper part B, which is closed by the lid 0. On the upper edge of said upper part B are arranged the conical nozzle-openings a, each terminating on the outside in a fine. aperture,so that after screw.- ing on the lid 0 small nozzles arranged in a circular line are obtained. The water fl'ow-- ing into the central nozzle issues consequently in fine radial sprays, which strike against stop-surfaces D, Fig. 5, which can be closed or have the shape of a sieve or consist of several plates. These water-sprays are dispersed on striking against these surfaces.

In producing the required fineness of the individual sprays needed to obtain a serviceable dispersing action the apertures of the nozzles are made extremely fine, and it is therefore necessary to retain the impurities which the water under pressure always containsbefore the latter issues out of the centralnozzle. For this purpose there is inserted between the body A of the nozzle andthe upper part B a sieve b, Fig. 1. This sieve is connected water-tight both with the body A and the upper part B by means of an inlaid. packing-ring d, Figs. 1, 3, and 4, while the cross-piece e in the upper part B takes up the pressure exerted by the water on the sieve and prevents the. latter from getting torn. The sieve Z) retains the impurities contained in thewater under pressure. If in course of time the nozzle-apertures should become stopped, the lid 0, held down by means of thescrew f,.screwed down into the cross 0,

is removed after looseningsaid screw, and all the nozzlefapertures a lie open to examination, so thatby means of a-brush they can all be easily cleaned at once. The cleaning of all these. nozzles does not require any more timethan that required formerly to clean one single nozzle. Besides this, the central nozzle requires less room and the cost of its man ufactureis far less than that of the dispersing contrivances generally used to produce fine water-sprays, in which a nozzle is required for each spray.

The cleaning of the sieve I) is effected as easilyas that of the-nozzle-apertures a. For this-purpose the upper part B is screwed off thebody of the nozzle A. The sieve b, which lies now free, can be taken off and brushed off. After replacing the sieve b in its former position and screwing. on the lid 0 the central nozzle is again in working order ready for use.

Inthe central nozzle (shown in section in Fig. 1 and in plan in- Fig. 2)'the water-jets obtained. are directed. horizontally. If oblique jets are required, the central nozzle (shown in section in Fig. 3and in details in Fig. 4 on a larger scale) can be used advantageously. This nozzle consists, likewise, of thebody A, the upper part B, and the lid C. The sieve b madewater-tight by means of the packing-ring d, retains likewisethe coarser partsor impurities of. the water, butdoes not bear, as in the foregoing construction, against a cross-piece connected with the top part, but againsta strong piece of perforated metal I), which take up the pressure of the water and prevents the sieve b from getting torn. The

plate 1; lies on top of the packing-ring d,

which renders both the body A andv upper part B water-tight, so that the water under pressure cannot run around the edges of the sieve I) and plate I).

In the construction shown in Figs. 3 and 4 the nozzle-apertures a are oblique, and the upper edge of the. top part B contains one part of the nozzle-apertures, while the lower edge of the lid 0 contains the other part of the apertures. Thus when the lid O has been removed the parts forming the apertures of the nozzle lie open to view and are easily cleaned by means of a brush. However, as the wear cannot be avoided, and in order that the apertures of the nozzles can be rebored, the direction of the latter is such that after removingv the upper part B and the. lid 0 a needle can. be introduced in the said apertures, as shown by the dotted lines on Fig. 3.

The body A, the upper part B, and lid G are held together by means of a clamp E,the hooked ends of which rest against the pro.- jections g'of the body A, whilethe pressurescrewf, passing through the clamp-presses on the lid 0.

In order to be able to bring the lid G'exactly on the upper part B, so that the parts formingby their reunion the nozzles maybe exactly opposite to each other, the upper part B and the lid G are provided with centeringpins or the centering device represented is applied. In the latter case there arearranged on the upper part two flaps h, forming; a groove. After the openings at inthe upper part and lid have been worked on, a plate z', fitting exactly in the groove left between the flaps h, is soldered to the lid G. The plate z secures the exact replacement of the lid- C on the upper part B always in the same position.
