L. J. STERN SPRAYING DEVICE Filed Feb. 15, 1939 IN VENTOR.
Patented July 16, 1940 UNITED STATES SPRAYING DEVICE Louis J. Stern,
New York, N. Y.
Application February 15, 1939, Serial No. 256,536
Myinvention relates to spraying devices and refers particularly to resilient devices of this character containing two connected compartments.
The usually employed resilient spraying devices comprise a wall of resilient material en-. closing a single compartment connected with the atmosphere by means of a plurality of openings. Powder is placed within the compartment and ejected by a plurality of compressions upon the sides of the device.
It is evident that in devices of this construction the powder will not be ejected until the incoming air following the release of pressure has agitated the powder to such degree that portions of it will be carried out by the outgoing air during the compression periods, and that, therefore, repeated pressure and release movements must be made to accomplish the spraying efiect.
It is further evident that when the device is in a perpendicular position it is practically impossible to perform any spraying efiect, especially when there is only a small quantity of powder in the container.
My invention, however, presents a device which will readily produce an effective spraying effect irrespective of the position of the device, and is as readily applicable for spraying purposes when it is in perpendicular position as otherwise.
A noticeable feature of my device is that it will eject all of the contained powder when it is in an upright position, thus presenting advantages not possessed by one-compartment spraying devices.
The construction and advantages of my invention will be readily understood by a consideration of my specification and its accompanying drawing illustrating one form of my device and in which similar parts are designated by similar numerals.
Figure 1 is a vertical cross-section of one form of my device.
Figure 2 is a top plan view of the device of Figure 1.
The particular form of a device of my invention shown in the accompanying drawing comprises a container having the resilient side I0,
the upper portion II of which is sloped inwardly and then upwardly to form a neck 12, the latter Figure 3 is a section through the line 33 of Positioned within the lower end of the container is closed by means of the plug l6. Fixedly positioned within the container and a suitable distance from the top thereof is a partition ll having a plurality of somewhat conical-shaped openings l8| 8 therethrough.
The side wallsof the container may be composed of sufiiciently thick Celluloid, rubber, cardboard or other proper resilient material, the openings l8l8 may be of cylindrical or other shape, the partition I! may be of any suitable material and may be placed at any suitable position within the container, and the latter may be of any desirable cross-sectional shape.
The operation of the device is as follows: Powder I9 is placed within the lower compartment of the container. When the device is in a horizontal or angular position, repeated pressures of the side It) into the position shown in dotted lines l0, l0 and the following releases of such pressure, the powder will be forced through the opening I8 into the upper compartment and thence outwardly through the openings l5|5. If during these operations, the device assumes a perpendicular position, and there is any powder in the upper compartment, repeated pressure upon the side II] will produce an ejection of this powder through the openings I5--|5,'and as the amount of powder forced from the lower compartment into the upper compartment is greater than that ejected through the openings l5-I5, there will be an accumulated body of powder in the upper compartment, which will be ejected through the openings l5--I5.
If, however, there is no powder in the upper compartment, sufficient powder may be readily introduced therein, by inverting the device, thus allowing powder to flow from the lower compartment into the upper compartment through the openings l8-l8.
It is to be further noted that the ejection of powder from my device is much more easily accomplished than it is in devices of this character which do not have two compartments.
In spraying devices having only one compartment, the powder must be in contact with the perforated closure, or pressure and release must be frequently and rapidly repeated in order to allow the incoming air to agitate the powder into an air suspended dust.
In my spraying device, however, there is always considerable air below the powder mass in the upper compartment, and hence, the compression of the lower compartment will force this air through the openings I8--l8 and outwardly and efiectively than is possible with a one-compartment device.
I do not limit myself to the particular size, shape, number, arrangement or material of parts shown and described as these are given solely as a means for clearly describing the devices of my 20 invention.
What I claim is:
1. A spraying device comprising. a resilient container, a closure for one end of said container, a partition having a plurality of downwardly extended pyramidal openings directed toward said closure, said partition dividing said container into two compartments and a foraminous closure carried by the open end portion of said container and positioned horizontally to the plane a of said partition.
2. A spraying device comprising a resilient bottle-shaped container having a body portion and a neck portion, a. closure for the bottom of said body portion, a. partition intermediate of said bottom and said neck dividing the device into 'two compartments and having a plurality of downwardly extended pyramidal-shaped openings and a foraminous closure carried by said neck.
