A TOMIZER FOR DAMPENING FABRICS.

SPEcIFIcA rIoN forming part of Letters Patent No.410,187, dated September 3, 1889.

Application filed January 18, 1889- Serial No. 296,697. (No model.)

To all whom it. may concern.-

Be it known that 1, MICHAEL PARTINGTON, a citizen of the United States, residing at Fall River, in the State of Massachusetts, have invented certain newand useful Improvements in Atomizers for Dampening Fabrics, ofwhich the following is a description in such full, clear, concise, and exact terms as will enable any one skilled in the-art to which my invention appertains, or with which it is most nearly connected, to make and use the same, reference being had to the annexed drawings, making part of this specification, and to the letters and figures of reference marked thereon.

Similar letters of reference indicate corresponding parts in all the figures of the draw ings.

As is now well understood in the arts, cotton goods before they are calendered are conditioned by dampening or sprinkling in The ordigoods consists of a circular brush, the ends of the bristles of which dip into a trough containing water, which water, when the brush is revolved by centrifugal action, is thrown upon the goods. There are many objections to such a device when employed for this purpose. It is desirable that the water be sprinkled upon the goods in as small drops or as fine spray as possible, and that it be applied evenly over the entire surface. Besides the inherent defects of a brush as a means for dampening the goods may be mentioned the fact that the bristles are apt to become loosened and fall out, and that part of the brush becomes inefficient for sprinkling purposes, since it causes the goods to be unevenly and unsatisfactorily dampened.

'It is also impossible to regulate with uniformity and with accuracy the amount of water thrown upon the goods by such a device; nor is it possible to insure-an even distribution of the water over the entire surface. This regulation and uniformity is a matter of the utmost importance in conditioning the cloth, because if too little Water be thrown upon the goods they will not be properly ironed in passing through the calender-rollers, and if too much be thrown upon them they are apt to mildew after being calenevenly over the entire surface.

provide a more efficient sprinkler, and its adprint works for conditioning the goods before. calendering, consists in the economy of power employed and in the fact that the wateris more evenly applied to the goods; that it is the time necessary to elapse between the sprinkling of the cloth and passing it through the calender-rollers. By means of my improved sprinkler the goods are in an improved condition when theyleave the calender-rollminished.

The followin is a descri tion of the accomtherein, while the novel features of my invention will be specifically pointed out in the claims concluding this specification.

Referring to said Figs. 2 and 3, H is a pipe having a sorew-threaded section. This tube H extends down beneath the surface of the water in the tank, and is open both at its top and bot-tom. Surrounding the tube H is a tip or tapering casing G, fitted so as to leave an annular space between the exterior wall of the pipe and the interior wall of the casing at their upper ends, having a web I, provided with a female screw taking in the screwthreaded section of the pipe H. The lower end of easing G is provided with a shoulder L and a screw-threaded portion M. W K is a sleeve having a smooth level under side to form an air-tight joint with the top of the trough A, to'which it is soldered or cemented, and having an internal screw-thread (Shown taking with the thread M 011 the lower end of the casing G.

J is a packing-ring between the shoulderL and the sleeve K.

The operation of the device illustrated is as follows: Air under pressure is introduced through the duct E into the trough A. This air-pressure on the surface of the water in said trough forces it up through the tubes H and out of their upper ends. The air under pressure in the tankA passes up through the openings in the webs I, and out through the annular space between the exterior of the tube H and the interior of the casing G in streams impinging upon the water-jet. The air thus issuing from the upper end of the casing Gr comes in contact with the stream of water issuing from the tube H, thereby disintegrating and atomizing the water into the form of a spray upon the goods. The shoulder L upon the casing G is provided with milling at its outer edge. By turning the pipe H with a right-hand or a left-hand revolution it will be seen that the relative position of the pipe H may be varied and its projection through the upper end of the casing G adjusted. The object of this adjustment is to cause a coarser or finer spray to be thrown upon the goods, since the farther the tube H projects the less will be the dispersing or atomizing action of the column of air passing from the end of the casing G, and the larger will be the drops thrown upon the cloth, while as the pipe H is relatively depressed or withdrawn the greater will be the dispersing or atomizing action of the air column and the finer will be the spray thrown upon the cloth. By experiment I have ascertained that a pressure of one pound in the trough A will throw a spray from seven to eight .feet high.

The goods dampened with my improved sprinkler are much better conditioned than those sprinkled in the ways already known employed.

and practiced, and the cloth after it has been dampening-spray and the evenness with which it is applied to the goods.

It will of course be understood that I do not limit myself to the precise elements or combinations of elements illustrated, and hereinbefore described, since many modifications not affecting either the principle or pun pose of the invention may be employed witlr out departing from its spirit or the scope of the following claims.

It will also be understood that my improved sprinkler is adapted not only to the dampening of goods in bleaching, dyeing, or print works to condition them for the calender-roll ers, but that it may be applied to other and analogous purposes.

My sprinkler is especially usetul'in dampening those materialssuch as velveteens Where steam or a dampening agent is now These goods cannot be sprinkled with a brush, as water, if it touches them in For this reason steam is employed to dampen these goods, and this not only makes it inconvenient to work in the room where the dampening is being done, but the steam rusts all machinery which may happen to be near it.

My sprinkler will throw the water up in such fine spray that it resembles a fog.

Having thus described the form in whichl prefer to embody my invention, what I claim, and desire to secure by Letters Patent, is-

1. In a sprinkler, a trough for containing liquid and air under pressure, a sleeve attached to said trough, a tip removably attached to said sleeve, forming a tapering chamber in communication with the air-space in said trough, and a tube, one end of which is to be immersed in said fluid and the other end of which projects outside of said trough, said tube having provision, substantially as described, for enabling it to be raised and lowered through said sleeve while the sleeve remains fixed to regulate the spray.

2. In a sprinkler, a trough for containing liquid and air under pressure, a sleeve attached to said trough, a tip removably attached to said sleeve, provided with aweb having a screw-threaded aperture theretlrrough, said tip forming a tapering chamber in communication with the air-space in said trough, and a tube, one end of which is to be immersed in said fluid and the other end of which projects outside of said trough, said tube being provided with a screw-threaded section taking with the screw-threaded aperture in the said web, whereby it is adjusted, substantially as described.

' 3. In a sprinkler, a trough for containing liquidiand air under pressuremn air-chamber side end of said tube, substantially as deformed at one end of said trough, combined with a tube, one end of which is carried outside of said trough, and a casing having a, chamber in communication with the air-space in said trough, and having an opening in clined with relation to the opening in the outscribed. h U
