1 Claim.
This invention relates to powder distributors and is particularly concerned with an improved and simplified hand-duster adapted to be employed for the application of insecticidal, germicidal, and fungicidal dusts, and other powders.
It is an object of the present invention to provide an improved duster for the distribution of powders. It is a further object to supply a such article of simple construction and low initial cost and adapted to be manually operated with a minimum of exertion. An additional object is to supply a small hand-duster of such design that it may be employed for the successive application of an assortment of dust compositions without the cleaning or dismantling of the operative structure. Other objects will be evident from the present drawings, specification, and claim.
The invention provides an improved powder distributor in the form of a hand-duster of simplified design. This cluster comprises a collapsible sidewall disposed between two rigid end plates to form an air chest and bellows. The preferred form of the bellows is tubular although not necessarily. A convenient mode of construction consists of a seamless tube of flexible and collapsible plastic film, the ends of which are fastened to the end plates by detachable ring clamps. This permits the ready replacement of the bellows sidewall.
The bellows assembly includes an air-intake port or ports with check valve and an air-outlet port. tional. Conveniently, although not necessarily, the air-intake and outlet ports are positioned in opposing end plates of the bellows structure, and the orifice of the inlet port is substantially greater than that of the outlet port. Also, the end plate opposed to that including the air-outlet port has a suitable handle or bail.
The air-outlet port opens into an air-discharge tube attached to and extending outwardly from an end plate of the bellows. The length of this tube is such as to open into the throat of a dust container attached to the assemblage as hereinafter shown. Concentric to this air-discharge tube and of greater diameter is a handhold tube attached to the end plate. The handhold tube is spaced from the air-discharge tube to form a mixing chamber. The outer end of the handhold tube opens into and is adapted detachably to engage a dust container. Thus, there may be positioned around the open end of the handhold tube a screw cap or plate by which a bottle or other dust container may be attached or clamped to the assembly, or the open end of the tube may A check valve on the outlet port is op- 2 be encompassed by a cork or rubber stopper of suitable size to engage the mouth of the dust container.
Attached to and opening out of the mixing chamber provided by the handhold tube, and
preferably adjacent to the point of attachment of the latter tube with'the bellows end plate, is a delivery tube through which the ultimate airdust mixture is expelled from the device. Either rigid or flexible tubes or nozzle devices may be attached to the end of the delivery tube.
One manner of construction of the device according to the present invention is illustrated in the appended drawings in which Figure 1 is a perspective view in side elevation of the handduster with dust container attached. Figure 2 is a sectional view extending longitudinally and centrally through the duster on the plane indicated by the line 2-2 of Figure 1. Corresponding and like parts arereferred to in the following description, and designated in the figures of the drawing by similar reference characters.
Referring to the drawings, a tubular collapsible wall 7! is disposed between two circular and rigid end plates I and I0 and fastened thereto by detachable ring clamps 6 to form a bellows and air chest 8. The end plate I includes a suitable handle or ball 2 and air-intake ports 3 opening into the air chest of the bellows 8. A rubber flap check valve 5 is positioned over the air-intake ports 3 and held firmly to the end plate I by a rivet t. An air-outlet port 9 opens through the end plate In into an air-discharge tube H extending outwardly from the end plate I0 and into the throat of a dust container I5. Concentric to this air-discharge tube II is a handhold tube I3 attached to the end plate Ill and of greater diameter than the air-discharge tube II. The tube I3 is spaced from tube ll to form an airdust mixing chamber I2, the outer wall of which provides a means for holding the duster. A screw cap I4 is positioned around the open end of the handhold tube I3 and engages a threaded top formed on the dust container I5. Entering the mixing chamber I2 and attached to the handhold tube I3 at a point adjacent to the point of attachment of the latter with the end plate I I] is a delivery tube I6 through which the air-dust mixture is expelled.
In operation, the dust container I 5 is filled with a suitable quantity of dust and engaged to the assembly by the screw cap I4. The operator takes the handhold tube I 3 in one hand and the handle 2 in the other, directs the delivery tube I6, or an extension thereof, in the direction of the surface or object to be dusted, and pumps the bellows 8. Air asses into the air chest by way of the air-inlet ports 3 and is expelled through the airoutlet port 9 by way of the air-discharge tube 1 I into the dust container l5. This causes the dust to be suspended in the air stream and to move into the mixing chamber I! at such a velocity as to cause sa flpw a a m lish th r u h mixing of=therair and dust. The homogeneous air-dust mixture is then expelled through the delivery tube l6.
When it is desired to change dust compositions all that is required is to disengage the dust con tainer I5 and substitute therefor a-zcontainer; filled with a difierent dust materials To cle'anse the bellows and air discharge tube of the duster, it is suflicient to pump the bell oygs several; times before attaching a new dust container.
The bellows sidewalls I may be constructedof leather, rubber, flexible plastic film, canvas, or
