FFKQE WILLIAM J. KELLEY, OF CENTRAL FALLS, RHODE ISLAND.

HEAD FGR HUMIDIFYING APPARATUS.

Application filed July 26 To all 1071.0?!1 it may concern:

Be it known that I, \VlLLL-XH J. KELLEY, a citizen of the United States, of Central Falls, in the county of Providence and State of Rhode Island, have invent-ed certain new and useful improvements in Heads for Humidifying Apparatus, of which the following is a specification.

This invention relates to that class of apparatus for moistening air, particularly in factories for treating textile materials, in which water and air under pressure are admitted simultaneously to at delivering conduit on nozzle, which is provided with means for causing the water to be distributed in the form of tine spray or fog by the air pressure, the delivering conduit being provided with deflector, which is opposed to the delivering end, so that the air and water impinge upon the deflector, and are distributed in the form of a fine spray or fog. Such apparatus is illustrated in Letters Patent No. 887,726, granted to me May 12, 1908.

One of the objects of the present inven tion is to provide a simple device of the character described, and which shall be stronger and more durable than the structure illustrated in said patent.

Another object is to provide the head of the apparatus with means for determining the direction in which the film of spray shall be projected.

Another object is to provide a head having means to determine the minimum amount of flow.

With these and other objects in view, the invention consists in the improvements which I shall now proceed to describe and claim.

Of the accompanying drawings, forming a part of this specification,Figure 1 is an elevation of the parts of the apparatus embodying my present improvements. Fig. 2 represents a section on line 2 2 of Fig. 1. Fig. 3 represents a section on line 33 of Fig. 1. Fig. l is a view similar to Fig. 3, but illustrating a slightly different form of cage.

The same letters of reference indicate the same or-similar parts in all of the figures.

Referring first to Figs. 1, 2, and 8, the

lower end of the delivering conduit 15, to

which water and air under pressure are supplied, as explained in my former patent referred to, is provided with a stop shoulder Specification of Letters Patent.

Patented May 5, 1914. Serial No. 781,412.

16, and is externally threaded below said shoulder. The extreme lower end of the conduit 15 is notched or recessed, as at 18, for a purpose hereinafter explained.

Removably secured to the lower end of the conduit 15, is a cylindrical cage 19, the up per portion of said cage being internally threaded to engage the threaded portions 17 of the delivering conduit. The cage is laterally slotted, as at 20, the construction being preferably such that when cage 19 is screwed firmly to position against the stop shoulder 16, the slots 20 will be opposite the recess-es 18 formed in the lower end edge of the delivering conduit. The deflector 21 having a face 22 opposed to the end face of the delivering conduit, is externally threaded for a portion of its length, to engage internal threads in the lower end of the cage 19, a set nut 23 being employed to hold the deflector in any position to which said deflector may be adjusted vertically in the'cage. The deflector 21 is preferably provided with a longitudinal cavity 24, which forms an air chamber, the mouth of which is surrounded by the face 22.

It will now be understood that in operation the water and air under pressure can escape only in the direction predetermined by the direction in which the slots 20 are formed. The object of preventing a flowor discharge of the film of spray in all directions is to prevent a discharge directly toward or over machinery which might itself, or the work being done on such machinery, be detrimentally affected by the immediate contact therewith of fine drops resulting from condensation of the spray; for instance, with such a structure illustrated in Figs. 1, 2 and 3, the direction of discharge may be along an aisle or passageway between looms, or other textile machinery, discharge in other directions being prevented by the uncut or solid portions of the cage. The cage is readily removable and may be replaced by another cage differently slot-ted. For instance,-a cage having four slots 20, as shown in Fig. 4, would permit of the discharge of the spray in four predetermined directions.

It is to be understood that I do not limit myself to the number of slots in the cage, nor the sizes of those slots. For some purposes it might be desirable to employ a cage with slots which almost meet, so as to direct.

substantially a continuous circular film.

It is to be understood, of course, that when the deflector is in operative position, such as shown in Figs. 1 and 2, the face 22 and the opposing end of the conduit 15, form the sides of a narrow crevice through which water flowing through the conduit 15 will. be forced outwardly in thin streams of fine spray or fog, under the pressure of air which is supplied to the conduit in the manner explained in my former patent referred to. With the parts adjusted as in Figs. 1 and 2, the streams will be projected in two opposite directions, with the middle of each stream. somewhat thicker than the edges thereof, this being due to the recesses, 18. By loosening the set nut 23 and adjusting the deflector 21 until its upper face contacts with the end of theconduit 15 between the recesses 18, and then tightening the nut 22: again, the streams projected will be limited to the. amount that can pass through the relatively narrow passageways formed by the recesses 18. This, therefore, will determine the minimum amount of water that can be projected during a given time. If n ore is needed, it is only necessary to loosen the set nut 23 and lower the deflector 21, returning the set nut to position, rendering the adjustment permanent. In other words, the structure such that a plurality oi streams may be delivered through the recesses 18 and through the cage openings 20. The thickness as well as the width of these streams may be varied, the larger sizes of streams filling or nearly filling the openings 20, the minimum being the amount which can pass through the openings which result from the "formation of the recesses 18, when the deflector member is adjusted so as to have the face 22 bear against the end of the conduit 15.

I claim A humidifying apparatus comprising a delivering conduit having an open end provided with lateral recesses, a cage re1novably connected with the conduit and having side openings the length and width of which exceed the length and depth of said recesses, and a deflector member adjustably connected with the cage and having a. face below the open recessed end of the conduit, whereby a plurality of streams may be delivered through said recesses and cage openings and the thickness and width of said streams may be Varied.

In testimony whereof I have aflixed my signature, in presence of two witnesses.
