SPECIFICATION forming part of Letters Patent No. 256,621, dated April 18, 1882.

Application filed March 17, 1852. (No model.) 7

spray or'mist for the purpose of moistening, the air in factories where silk or other textile fibers are spun, in order to render the fibers more soft and flexible and less liable to break in spinning. For this purpose itis quite important that the spray or'mist be of such impalpable' fineness as will immediately'become dissipated by evaporation or absorption in the air, without presenting any sensible particles which would settle in the form of wet drops, even of point-likefineness.

In a former patent, issued to me September 20, .1881, N0. 247, 151, I have shown a moistening or atomizing jet of novel construction specially adapted for producinga mist or spray for the described purpose, and of such exceeding fineness as to be almost entirely free from any particles of palpable size. It happens, however, occasionally in the operation of this 3o jet that a few sensible watery particles will be endthe main feature of my invention consists in the combination, with an atomizing-jet, of a case surrounding the same, closed at the bottom and open at thetop or sides, adapted to arrest all sensible particles, while allowing the fine impalpable particles of, mist to rise and diffuse freely into the air, thereby moistening the air eflectually and avoiding the possibility of producing any deposit of wet.

Another feature of the invention consists in the combination, with the atomizing-jet and its inclosingcase, of a deflector placed over the jet within the case to serve to more minutely divide the spray, as well as prevent the rise or discharge of any sensible particles out of the case.

The invention also embodies several minor features, as-hereinafter fully set forth.

Figure l of the-annexed drawings presents a sectional elevation of my improved moistening apparatus, showing two moisteners; and Fig.2, a plan view of one of the moisteners with the deflectors removed, while Fig. 3 gives a plan view of the removed deflectors.

In Fig. 1 a indicates the water-supply pipe, which may extend, for instance, along. the ceiling of the spinning-room or other apartment in which a moist atmosphere is required. This pipe will of course be suitably fastened in place and connected with an elevated reservoir of water, or with street-mains, or with a force-pump or other source which will supply it with Water under pressure, as will be understood. From the supply-pipe a branches 1) extend atsuitable intervals, which are provided with regulating-valves c and jets d d, fron1 which minute atomizing-jets of water may be discharged under high pressure when the valves 0 are opened. These jets may be constructed in a simple way, as represented in Fig. 1, so as to discharge, simply a very fine stream of water,which, being projected against dispersing-plates or reflectors c e, placed over and before the jets, will cause the fine stream tobe broken up into a fine spray or mist. In this case, however, a very largepart of the spray or mist would consist of sensibleparticles, which would rapidly settle to the floor in the form of a wet deposit, and a portion ot'iinpalpable particles or fog, which would readily diffuse into the air. Now, in order to allow only the fine fog to diffuse into the air and arrest the drops, Isurround or inclose the jets and deflectors with the casing f, which preferably extends well above and below the jets, asshown, but is closed or covered at the bottom and open at" the top. By this means it will therefore be readily seen that all the fine impalpable watery particles or mist will readily float up out of the case and dill'use in all directions into the air, while the palpable particles or fine drops will fall to the bottom of the case. Now, from the bottom of the case a discharge-neck, '6, extends and conn: cts with a small piece of rubber tubing, m, which communicates with a waste-pipe, 7., so that all the watery drops falling to the bottom of the case have free chance to trickle out or flow away as fast as they are produced without accumulating in the case, as will he understood.

The casing f is preferably a sheet-metal cylinder with a conical bottom, as shown,and is preferably suspended at the top by chains or wires 9 trom an adjustable elasping-sleeve, h, which is clamped upon the branch pipe I), and may thus be adjusted up or down, so as to set the casing higher or lower with reference to the jets. The deflectors 6 also extend from a clasping-sleere, 1:, adjustable up or down on the branch pipe, so that they may also be adjusted up or down with relation to thejets, which adjustment will regulate the volume of mist discharged from the top of the case.

Under the conical bottom of the casing is arranged a larger or secondary cone or catchbasin, l, which is secured to the conical bottom of the casing or to the discharge-neck t', which basin catches or arrests any condensation which may form on the outside of the casing, and which will trickle into the basin and be thus directed thereby through perforations in the neck i into the waste-pipes m It, as will be understood. It will be readily seen that the discharge of cold watery spray within the easing and the evaporation outside of it will render the casing quite cold, and hence produce a condensation of moisture from the air on its exterior, asjustreferred to, which, by the means described, is thus conducted 011' and prevented from dripping to the floor onto the masses of fibers, which may be placed below the moistcner. I

I prefer to prolong the branch pipes 12 beyond thejet so as to enter the discharge-neck t of the casing, and thus serve to steady the casing around the jets and guide the casin g in its adjustment up or down on the pipe, the end of the pipe being of course closed or plugged and a loose fit in the discharge neck.

I prefer to arrange the moisteners in true vertical position, as shown at the left of Fig. 1; but they may be arranged at various inclinations, or nearly in a horizontal position, as seen on the right of Fig. 1.

Instead of employing the simple jets shown in Fig. any suitable form of spraying or atom' izing jet may be used. I prefer, however, to employ thejet previously patented to me. (Before referred to and shown in Fig. 2.) In this case the jet is duplex or discharges two minute streams of capillary fineness at right angles to each other, or nearly so, which impinge against each other at a short distance from the orifice of the jet-nozzles d d, and thereby become dissipated into the finest possible spray or mist, which consists almost entirely of impalpable particles, which readily float and diffuse in the air and contain only occasional particles of any palpable size, which, however, are arrested by the casing f and deflectors c, as before described. The deflectors cc will be placed over my improved jet in about the same position as seen Fig. 1 to deflect all palpable particles downward, as will be understood, the jets not, in this case, impinging on the deflectors.

It is not essential that the casingsfbe connected at the bottom with awaste-pipe, as they may simply serve to receive and accumulate the palpable watery particles until removed; but the construction shown is preferred.

It will be readily understood that where the catch-basin l is used below the casing it is not essential that the casing be itself provided with the closed conical bottom f, as this may be dispensed with and the bottom left open,

but placed directly over the catch-basin l and neck 1, as shown, which basin will thus cover or underlie the bottom of the casing and form in effect a close bottom therefor to receive and conduct otf all the falling drops with substantially the same effect as described for the preferred construction.

What I claim is- 1 In an air-inoistencr, the combination, with a spraying or atomizingjet, of a casing inclostag the same and adapted to permit the impalpablc misty particles to escape and diffuse into the air while arresting or retaining the heavy or palpable particles, substantially as herein set forth.
