SPRAYlNG-MACHINE.

SPECIFICATION forming part of Letters-Patent No. 694,106, dated. February 25, 1902. Application filed Aprilll, 1901. Serial in. 55,435. (No model.)

' To ctZZ whom it may concern:

Be it known that we, GEORGE A. METOALF and RALPH K. HALL,'citizens of the United States, residing at Woonsocket, in the county of Providence and State of Rhode Island,

have invented new and useful Improvements.

in Spraying-Machines, ofwhich the following is a specification.

Our invention relatesto machines for break-- ing water and other fluids up into fine spray, and while designed more especially for spraying cloth precedent to the pressing thereof is adapted tobe used to advantage for oiling wools and humidifying the atmosphere of rooms, as well as in other connections. It has for its general object to provide a spraying-machine embodying a simple, inexpensive, and durable construction whereby water taken from a reservoiris thrown in a fine spray free from individual drops, the latter being especially advantageous when the machine is employed to spray fine fabrics, since drops of water produce aclouded appearance on such fabrics.

With the foregoing in mind the invention will be fully understood from the following description and claims when taken in conjunction with the accompanying drawings, in which- Figure l is a side elevation of a cloth-spraying machine embodying our invention with a portion of the main frame broken away. Fig..

2 is an enlarged detail broken plan of the sprayer or humidifier of the machine with a portion of the spraying-cylinder in section. Fig. 3 is a vertical section taken on the broken line 3 3 of Fig. 2; and Fig. 4 comprises disconnected perspective views .of a portion of the cylinder-shaft, one of the spraying-disks, and one of the spacing-collars for holding the disks the proper distance apart.

Similarletters of reference designate corresponding parts in all of the several views of the drawings, referring to which- A is the main frame of the cloth-spraying machine, having a cloth-table a; B, one of the brackets which are connected to supports a on the frame and support in turn a frictionbar 0, a stretch-roll D, and a guide-roll E; F, a cloth-carrying or take-up roll journalcd in suitable hearings on the frame; G, a fiddlestick connected to the frame; H, .a cloth-roll movable on the fiddle-stick in the usual manner and weighted, as indicated byb; I, adriveshaft journaled in suitable bearings on the frame, and J the cloth to be sprayed, the said cloth being taken from the table a. overthe friction-bar 0, under the stretch-rollD, 'over the guide-roll It, and between the take-up roll' F and the cloth-roll H and being de-' signed to be wound on the latter after the usual manner. Theshaft I is provided with a pulley 0, connected by a belt cl with a pulley e on a shaftf, which shaft also bears a pulley g, connected by a belt h with a pulley't' on the take-up roll F, whereby it will be observedthat when the shaft I is rotated by any suitable means in the direction indicated by the arrow the take-up roll will be rotated in a similar direction and the cloth drawn in the direction indicated by the arrow over the sprayer or humidifier, presently described. Motion is transmitted from the take-u p roll F to the stretch-roll D through the medium ofa sprocket-\vheeljon the takeup roll, a sprocket-wheel icon the stretch-roll,

and a connecting-chain Z, the stretch-roll being rotated in a direction opposite to the direction of movement of the cloth, so as to retard the passage of said cloth and hold it taut,

J is the reservoir of our improved sprayer or humidifier, which is arranged on and connected to the frame and is provided with an inlet m for water and an overflow-pipe 'n, the latter having for its purpose to insure the maintenance of a uniform depth of water in the reservoir.

K is the spraying-cylinder, and L is a belt which takes around a large pulley p on the shaft I and a small pulley q on the cylinder- 0 shaft r and is adapted to rotate the sprayingcylinder at a high rate of speed. The spraying-cylinder in the preferred embodiment of the invention comprises the shaft 1' and sheetmetal disks .9, arranged at about the prop'or-.

' tional distance illustrated apart on the said shaft and held in position by interposed spacing-collars t, and when the said cylinder is driven at a velocity of from one to three thousand revolutions per minute the disks 3, pass- Ioa M M are drip-boards, which are inclined,-

as shown, with their lower portions in the reservoir J, and are connected to the end walls of said reservoir by brackets to.

N is a deflector, which is connected in a hinged manner to the drip-board M and is designed to be fixed at various angles of inclination through the medium of the pivotally-connected rack-bar v and the pin w,which said bar engages, and P is a shield, preferably curvilinear in form, which is connected in a hinged manner to the drip-board Mand is adjustably held over the cylinder K by the pivot-ed rack-bar w in engagement with a pin y on said drip-board M. When the shield P is adjustably fixed very near the cylinder K, the volume'of spray thrown by the said cylinder is quite small, and as the shield is moved in a direction away from the cylinder the volume of spray thrown from said cylinder is proportionately increased.

In the practical operation of our improvements the cylinder K is, as before stated, driven at a high rate of speed, and by reason of this and the arrangement of the disks 3 in the body of water in the reservoir it will be seen that the disks will take up films of water 'from the body in the reservoir and throw the same in the form of a fine spray free from individual drops against the stretch of cloth between the guide-roll E and the take up roll F. When the shield P is adj ustably fixed over and quite close to the cylinder, the volume of spray thrown by the said cylinder will be reduced and guided against the deflector N precedent to striking the cloth, with the result that the atomic division of the water will be increased and the liability of an individual drop reaching the cloth precluded. The dripboards M M have for their purpose to conduct any water thrown off by the cylinder K back into the reservoir J.

It will be appreciated from the foregoing that while simple and durable in construction our improved sprayer or humidifier may be depended upon to efiect a thorough atomic division of water or other fluid which it is desired to apply in an atomized form to cloth "or other material or throw into the atmosto be understood as confining ourselves to such specific construction and arrangement of parts, as such changes or modifications may be made in practice as fairly fall within the scope of our claims.

Having described our invention, what we claim, and desire to secure by Letters Patent, 1s

1. In a spraying-machine, the combination of a reservoir for water or other fluid to be sprayed, a rotary cylinder having disks at intervals of its length arranged and adapted to turn in the body of waterin the reservoir, a shield arranged over the cylinder, and a deflector against which the volume of spray is thrown.

2. I11 a spraying-machine, the combination of a reservoir for water or other fluid to be sprayed, a rotary spraying device, an adjustable shield arranged over the spraying device, means for adj ustably fixing the shield with respect to said device so as to regulate the volume of spray thrown therefrom, and an adjustable deflector against which the volume of spray is thrown.

3. In a spraying-machine, the combination of a reservoir for water or other fluid to be sprayed, a rotary cylinder having disks at intervals of its length arranged and adapted to turn in the body of water in the reservoir, drip-boards having their lower portions arranged to conduct water to the reservoir, a shield connected in a hinged manner to one drip-board and extending over the cylinder, means intermediate of said drip-board and the shield for adjustably fixing the latter in position, a deflector connected in a hinged manner to the other drip-board, and means intermediate of the latter drip-board and the deflector for adjustably fixing said deflector in position.

4. In a spraying-machine, the combination of a reservoir for water or other fluid to be sprayed, a rotary device arranged to raise water from the body in the reservoir and throw off the same in the form of spray, a shield arranged over said rotary device, and a deflector against which the volume of spray is thrown.

5. In a spraying-machine, the combination of a reservoir for water or other fluid to be sprayed, a rotary spraying-cylinder having disks at intervals in its length arranged in the body of water in the reservoir,drip-boards having their lower portions arranged in and connected to the reservoir, a shield hinged on one drip-board and extending over the cylinder, a rack-bar pivotally connected to the shield and engaging said drip-board, a deflector hinged on the other drip-board, and a rack-bar pivotally connected to said deflector and arranged to engage the latter drip-board.
