4 Claims.

An object of the invention is to provide a cleaning device which shall be simple and inexpensive in construction and simple in operation.

Other objects and advantages reside in certain novel features of construction, arrangement and combination of parts, which will be hereinafter more fully described and pointed out in the appended claims.

In the annexed drawing given by way of example, and in which like reference characters indicate corresponding parts throughout the several views:

Figure 1 is a side elevational view of the assembled device.

Figure 2 is substantially a longitudinal sectional view of the device.

Figure 3 is a bottom View of same.

Figure 4 is a transverse sectional View of the device.

In the said drawing I is a wood handle provided with indentations I8 and I9, adapted to receive the fingers and thumb of a user While in use, so that the device will not slip out of the hand. The handle is provided with

saw cuts

22 and 23 that extend the entire length of the handle, and are provided to receive the perforated plate II that is held in assembled relation with the handle by means of nails 24, or other suitable fastening means.

The bottom plate II is provided with aligned The integral portion I4' the handle I0, and is provided to close one end of the chamber 2l that is provided above foraminous vulcanite, Celluloid or other heat susceptive material that may constitute the plate II. The removable block IB that closes the other end of the chamber is held in place by the keeper I'I. The block I6 is removed to release the dust from the chamber 2|. The bottom plate is provided with a multiplicity of perforations 20 that lead into the chamber ZI. It will be noted that the plate I I is curved from side to side as well as longitudinally.

The operation of the device is as follows:

The cleaning device is rubbed quickly back and forth over the pile or nap of a rug or upholstery.

The frictional contact of the cleaning device with the article being cleaned, imparts heat to the device, which in turn imparts heat to the air in the chamber and expands it, its density is lessened and hence it is pushed upward by colder adjacent portions, which take their place only in turn to be driven away. The currents of warmer air flow away from the source of heat, and other currents of colder portions flow toward it. The

perforations introduce a relatively high resistance between the article being cleaned and the device and imparts a whisk to the pile or nap thus loosening up the dust particles having small kinetic energy. The plate is also negatively electried by the friction, and the negative electricity also assists in removing the dust particles.

Other applications and other modifications are contemplated within the scope of the present invention as will be apparent to those skilled in the art. It is therefore to be understood that the embodiment herein disclosed is to be regarded as illustrative of the invention and not restrictive, and the appended claims are to be construed broadly except as limitations may be necessary in view of the prior art.

Having described my invention what I claim as new, and desire to secure by Letters Patent is:

1. A device of the class described comprising a handle, a perforated plate mounted therein and forming therewith a chamber, and means for closing the ends of the said chamber supporting the ends of the perforated plate, one of the said means being bodily removable as a single unit so that the chamber may be cleaned.

2. A device of the class described comprising a handle, a perforated plate associated with the handle and forming therewith an air chamber and having a curved outer surface, the curvature i of said surface being such that it is concave longitudinally of the handle and convex transversely of the handle, and removable means closing one end of the chamber, the other end of the chamber being closed with a xed means.

3. A device of the class described comprising a handle, a perforated plate having aligned outer surfaces and also having a curved outer surface, the curvature of said surface `being such that it is concave longitudinally of the handle and convex transversely of the handle, the aforesaid curved surface coalescing with the aligned surfaces, the aforesaid perforated plate forming With the handle an air chamber, members for closing the ends of the air chamber, one of the aforesaid members being removable, a keeper for maintaining the said removable member, the other of the said members being fixed.

4. A device of the class described comprising a handle, a foraminous heat susceptive plate associated with the handle and forming therewith an air chamber and having a curved outer surface, the curvature of the surface being such that it is concave longitudinally of the handle and convex transversely of the handle, means for closing the ends of the air chamber, one of the said ends being removable.
