SPRAYING DEVICE.

Specification of Letters Patent.

Patented June 1, 1909.

Application led October 2, 1908. Serial N o. 455,810.

pressed air is employed to expel the spraying v materlal.

The object o f the invention is to provide a simple and economically constructed spraying device which is equally as well adapted for spraying powders as for spraying liquids and in which the spray is controlled by a simple valve, such as a push valve.

A further object of the invention is to provide a spraying device having a discharge chamber opening from near the bottom of the receptacle and in which the spraying material is confined by air pressure from beneath in position to be ejected from the nozzle when the outlet from the chamber is opened.

The invention. consists of the matters hereinafter described in the speciiication and more fully pointed out and defined in the appended claims.

In the drawings-Figure 1 is a central vertical section of a device embodying my invention. Fig. 2 is a transverse section thereof. Fig. 3 is a vertical section of the air pump. 4- is a section taken on line y-fz/ of Fig. 3. Fig. 5 is a view partly in section and partly in side elevation of the nozzle or spraying tip. Fig. 6 is an enlarged,

' fragmentary section of one form of the .dis-

charge pipe. Fig. 7 is an enlarged, fragmentary section of the discharge pipe shown in Fig. 1. Fig. 8 is an enlarged, fragmentary, vertical section of the air pump. p

As shown in said drawings, A indicates a receptacle of any preferred size and construction which is rovided with a top a and a bottom a', the atter of which is concaved or dished on its under side and is provided with a filling aperture in which is removably engaged a p ug a2. v

Rigidly sup orted within sald receptacle is the air pum the barrel b of which extends from near t e bottom of the receptacle upwardly through the top a and is provided with a. top or cover b having an axial aperture therethrough. Within said barrel, near the lower end thereof, is a centrally apertured valve seat b2, and beneath said seat is a valve closure b3 having a valve stem b4 thereon which extends downwardlyT through the bottom b5 of the barrel. A spring t6 engages at one end against the bottom b5 and at the other end against the valve closure b3 and acts to normally hold the closure against said seat. Said closure is provided near its .periphery with apertures t7 and the bottom t" 1s provided with apertures bs through which air may pass from the pump to the receptacle.

Slidably engaged in the top b of said barrel is a rod b9 on the lower end of which is an inverted cup-shaped plunger bo, adapted when the lrod is forced downwardly to fit closely to the sides of the barrel and force the air beneath the same into the receptacle where it is confined by the valve closure b3. When said plunger is raised, the edges thereof collapse and permit the air in the upper part of the barrel to pass beneath it.

The receptacle A is provided with a handie a3 on one side thereof, and rigidly engaged within the receptacle, adjacent the handle, is the discharge chamber C, which may be 'of any preferred construction, but which, as shown, is cylindrical and the lower end of which o ens in close proximity to the bottom a of t e receptacle. In the u per end of said chamber is a valve casing c which protrudes from the top of the rece tacle. A

valve stem c extends downward r through.

said valve casing and is provided with a valve closure c2 on its lower end adapted t0 seat against the bottom of the casing and close the passage therethrough. The upper end of said stem c .is provided with a head c3 and between the head and the top of the casing is a spring c4 adapted to normally hold the closure c2 seated.

A discharge pipe D is rigidly engaged on the top of the receptacle and opens at one` end from said valve casing c. The op o`- site end d of said ipe is provided wit a peripheral groove s and tapers from said groove to the extremity, as shown more clearly in Figs. 6 and 7. Connected on said tapered end is the pipe extension D', which is slotted in one end to enable it to be sprung onto said end d, and is provided on its other end with a top D2 having longitudinal slots d2 therein for the escape of the s raying material. Said extension is prefera ly curved, as shown in Fig. 1, to facilitate its use. By turning the extension, the liquid may be sprayed upwardly, downwardly pr to either side at.

The operation is as follows: The receptacle` is partially lled with the spraying material through the lling aperture in the bottom and air is pumped into the receptacle by means of the pump B until a sufiicient pressure is obtained to eject the spraying material. The air, of course, will rise above the spraying material in the receptacle, and, whenthe valve c2 is operated, the discharge chamber O will be illed and the material will be ejected through the discharge pipe. Willen the valve c2 is released, the pipe D is closed, but the discharge chamber will remain filled owing to the air pressure above the material in the receptacle.

vOwing to the close proximity of` the disy charge chamber to the handle a3, the valve c2 may be operated by the thumb of the 4hand holding the receptacle. Obviously a spray# ing device constructed in accordance with my invention is adapted to'provide a good spray and many details of form and construction may be varied without departing from the principles of my invention.

I claim:

1. In a spraying device, the combination of a cylindrical rece tacle closed at the top and having a dished ottom provided with aV lling opening, a plug to close the same, a handle on the side of the receptacle, an air pump extending into the rece tacle from the top, a vertical discharge cham er Within said receptacle, lying along the 'side of the same adjacent the handle, a valve casing in the upper end of the discharge chamber, a valvepiece which closes the opening into said valve chamber, `a stem for said valve-piece provided With a thumb piece in position to be de ressed by the thumb of the hand which holds the handle, a discharge pipe leading from the valve casing and extending across the top of the receptacle, a curved extension pipe swiveled on the end of said discharge pi e, and a nozzle on said extension pipe, su stantially as described.

2. In a spraying device, the combination j of a cylindrical receptacle, a handle on the side ol' said receptacle near the top, an air pump extending into the recepbtacle from the top, a vertical discharge cham er within said receptacle lying along the side of the same adjacent to the handle, a valve casing in the' upper end of the discharge chamber, a valvepiece, which closes the opening into said valve chamber, a stem Jfor said valve-piece provided with a thumb piece in position to be de ressed by the thumb of the hand which ho ds the handle, a discharge pipe leading from the valve casing and extending across and projecting from the top of the receptacle, the end of said discharge pipe being tapered and provided with a peripheral groove, a curved extension pipe constructed so as to be sprung over the tapered end of said discharge pipe and provided with a rib which engages wlth the groove on the discharge pipe, and a pointed nozzle on the end of said curved extension, provided with`longitudinal slots for G. Y SKINNER, H. L. PECK.
