BY azz/fezf//Qr gm, y Amy Patented June 13, 1944 SPRAYING DEVICE Lawrence T. Ward, Philadelphia, Pa., assignor to Knapp-Monarch Company, St. Louis, Mo., a corporation of Missouri Application July 7, 1941,seria1No. 401,337
5 Claims.
My present invention relates to a spraying device which may be used for spraying insecticide or other fluids.
One object of the invention is to provide a device which may be used for spraying insecticide without the necessity of having a manual pump or the like to effect the spraying operation, the device instead using a bulb of compressed gas or the like to produce the necessary pressure to displace the liquid from a container therefor.
A further object is to provide an insecticide spray unit which may contain a quantity of insecticide sealed against evaporation and ready at any time for instant use by the mere depression of a lever on the device, the lever operating a valve mechanism to control the spray as desired.
A further object is to provide spraying mechanism wherein the liquid is displaced by gas under compression and is atomized by introduction of some of the gas into the liquid stream during the dispensing operation.
With these and other objects in view, my invention consists in the construction, arrangement and combination of the various parts of my device whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims and illustrated in the accompanying drawing, wherein:
Figure l is a vertical sectional view through an insecticide spray device embodying my invention, the valve being shown in closed position and the apparatus being illustrated during the process of charging the vase with compressed gas from a Sparklet bulb or the like, and
Figure 2 is a similar sectional view showing the valve in open position and illustrating the action of the liquid and gas to effect the desired spraying operation.
On the accompanying-drawing, I have used the reference numeral I to indicate a suitable vase or container for liquid L, such as an insecticide. A removable head I2 is provided for the vase I0, the head being screwed on the vase with a gasket at I3 to eiect an airtight seal.
The head I2 has therethrough a passageway, indicated at P, in which is located a valve seat I4. A plug I5 is adapted to seat thereagainst under the bias of a spring I6. The plug I5 is provided at one end of a discharge tube T comprising a rst section II and a second section I8 coupled together as by a coupling nut I9. The sections I'I `and I8 are sealed relative to each other by a ground seat at 20.
The tube section I8 has a discharge nozzle 2| of any suitable shape.
mounted on the tube section I'I and serves as a lock nut for the coupling nut I9. It also serves as a shoulder against which the upper end of a lever L may engage for opening the valve, as shown in Figure 2.
The spring I6 is interposed between a closure nut 23 and a washer 24 on the discharge tube T and engages a head 25 thereof in which the plug member I5 is located. The Washer 24 serves as a seal so. that liquid through the valve will iiow through the bore of the discharge tube T instead ci past the spring I6 and out through the bore of the nut 23.
The passageway P at its extreme inner end receives a syphon tube 26 depending to a position where its lower intake end is located adjacent the bottom of the vase IU. The syphon tube 26 has a minute opening 2'I of a few thousandths of an inch diameter, which serves an important purpose, as will hereinafter be described.
The vase I0 and head I2 are adapted to be held in the hand of the user with the fingers engaging the lever L to depress it, as-shown in Figure 2. A rest member 28 is provided which forms a projection on the head I2 secured thereto by a screw 29. This projection is adapted to rest on the upper edge of the users hand between the thumb and rst nger. The` stop shoulder 28 thereby forms a convenient support for the spraying device when in use.
In the bottom of the vase I0, a fitting 30 is provided having a hollow piercing pin 3I. pin 3| is adapted to pierce a compressed gas bulb, such as a Sparklet bulb 32, when the bulb is forced against the pin by a holder 33 in a Well known manner. After the vase I0 is filled with the liquid L, the piercing operation is performed as illustrated in Figure 1, whereupon compressed gas passes upwardly in the form of bubbles 34 through the liquid L and fills the space above the liquid in the head I2. After the gas is discharged from A shoulder nut 22 is 55 the bulb, the bulb may be removed by unscrewing the holder 33 and the usual check valve in the fitting 30 will close to prevent escape of the liquid from the vase.
Whenever it is desired to use the spraying device, it is supported irl the hand, as already described, and the lever L depressed as in Figure 2, thereby causing the lever to pivot at point 34 on the head I2 and effect opening of the valve. The compressed gas in the head I2 will displace the liquid L upwardly through the syphon tube 26 and some of the compressed gas will slowly pass through the minute opening 2l, thereby mixing with the liquid and effecting atomiz'ation thereof The as it leaves the nozzle Il. Thus, the discharge fromthenozziewillbeinthei'ormotaspray rather than a needlelike stream ci, liquid.

Somechangesmaybemadeintheconstruction and arrangement of the parts of my device without departing from the real spirit and purpose oi' my invention. and it is my intenon to cover by my claims any modiiled forms o! structure or use of mechanical equivalents which may be reasonably included within their scope without sacrincing any of the advantages thereof.
