VIRGIL SATTERWHITE AND WELCOME A. DILLE, OF KANSAS CITY, MISSOURI.

BESILIENT CLEANING ATTACHMENT.

Application filed April 3, 1925. Serial No. 20,383.

To all whom it may concern:

Be it known that We, VIRGIL SATTER- WHITE and WVELcoME A. DILLE, citizens of the United States, and residing, respectively, .at Kansas City, county of Jackson, and State of Missouri, and Kansas City, county of Jackson, and State of Missouri, have invented certain new and useful Improvements in Resilient Cleaning Attachments, of which the following is a complete specification.

This invention relates to cleaning attachments, and particularly to attachable heads for vacuum sweepers or the like that can be used to clean walls, polished floors, window curtains and the like.

The primary object of the present invention is the provision of an attachable memher which has a cleaning body of material that loosens the dirt and dust as it is rubbed over the particular surface to be cleaned.

A further object of this invention 1s to provide an attachment with novel means for holding the cleaning body in place whereby the same may be. used without being drawn entirely into the hollow attachmenthead to render the device ineflicient or even 1nopera tive.

An even further object of the present invention is. the provision of a. cleaning attachment which includes a cleaning body having an outwardly extending annular flange to prevent the metal head from striking woodwork or other polished surfaces.

This invention further contemplates the use of a sponge rubber cleaning body which may have a bulge in the cleaning face thereof for imparting a rocking motion to the head and which also functions, to a certain extent, to preclude th article to be cleaned from sticking thereto.

One of the preferred ways of constructing a cleaning attachment embodying the present invention is shown in the accompanying drawing, in which:

Figure 1 is a front view of a cleaning attachment made in accordance with this invention.

Fig. 2 is a vertical central section of the same.

Fig. 3 is a vertical section of the attachment taken on line IIIIII of Fig. 1; and,

Fig. 4 is a bottom view of the attachment showing the mouths of the several passages through the cleaning body.

Referring particularly to the drawing,

wherein similar reference characters refer to like parts throughout the several views,

the invention has been illustrated in a structure which is adapted to be attached to the ordinary vacuum cleaner tube or the like, or to the suction tube of any system of that general character.

The hollow head 5 may be elliptic to permit thorough cleaning in corners, and should be formed of metal with no abrupt turns, as shown, to permit dust and dirt to pass freely therethrough to outlet passage 6, which continues therefrom from a point near the center of the top. Depending sides 7 extend from hollowhead 5 to embrace and hold a resilient cleaning body 8 which is preferably made of sponge rubber. Other resilient and porous substances may be employed if desired, providing it functions in substantially the same manner as sponge rubber. A plurality of dust passages 9 must be provided when sponge rubber is used, which permit all the dust and dirt loosened by the rough outer face 10 of the cleaning member 8 to pass out through hollow head 5 and outlet passage 6.

An outwardly disposed bulge 11 on the face 10 of the cleaning member 8 may impart a rocking motion to the attachment as a whole and precludes all the surface of said face 10 from bearing against the surface to be cleaned at once which would cause the same to stick thereto.

A network partition 12 supported within said hollow head as shown in Figs. 2 and 3 keeps cleaning member 8 from being drawn into head 5 by having the inner face thereof In the operation of this attachment, it is important that the rough face 10 be drawn over the surface to be cleaned with uneven strokes. The bulge 11 causes such action and precludes the face 10 from hearing too hard over its entire area at once. The multitude of pits and projections on the face 10.

of sponge rubber member 8 loosens the dirt and dust as it cleans and allows the same to escape through passages 9.

While the preferred form of construction has been shown, it is understood that it may be embodied in structures varying in size, shape, material used, etc., without departing from the spirit of the invention and the scope of the appended claims.

What is claimed is:

1. A cleaning attachment of the class described comprising, in combination, a hollow head having annular depending sides, a network partition within said i ead and a porous resilient body embrace "by said depending sides ar'i'd extending beyond the edge thereof, said extended portion having an outwardly disposed flange extending beneath and beyond said edge.

2. A cleaning attachment of the class described comprising, in combination, a hollow head having depending sides, a network partition Within said head, a sponge rubber body embraced by said sides with its inner face abutting said partition and a bulge formed on the outer face of said sponge rubber body, for the purpose and substantially as described.

In testimony whereof we hereunto aflix our signatures this 1st day of April 1925.

VIRGIL SATTERWHITE. VELCOME A. DILLE.
