Patented Dec. 31, 1940 UNITED STATES PATENT OFFICE DISPOSABLE DUST RECEPTACLE FOR BRUSH TYPE CARPET SWEEPERS Application September 5, 1939, Serial No. 293,422

3 Claims.

is a somewhat mussy operation and, in many in-v stances, mere tilting of the dust pans is not sufficient to entirely discharge debris therefrom. In any event the clearing operation involves the necessity of providing a receiver of some kind, often a piece of newspaper, and the probability of scattering of some of the debris during the 4) operation.

The object of my invention is to provide a carpet sweeper structure and associated debris receptacle of such character that the debris receptacle with its accumulated debris may be readily bodily extracted from the sweeper casing and disposed of as a unit.

The accompanying drawing illustrates my invention:

3O embodying my invention;

Fig. 2 is a vertical section in a plane at right angles to the axis of the brush;

Fig. 3 a perspective of my improved debris receptacle extracted from the casing of the sweeper; and

Fig. 4 a plan, on a smaller scale, of a blank from which the disposable debris receptacle may be formed.

In the drawing H1, I indicate usual traction 40 wheels between which is mounted the rotary brush ll driven by said wheels. The wheels support a casing l2 which envelopes the brush, and which is substantially like casings ordinarily found in sweepers of this type but differs therefrom in that it has no fixed top overlying the brush and adjacentlregions of the interior of the casing flanking the brush along each side.

The details of wheel mounting and brush 50 mounting and driving form no part of my present invention and may be of any desired construction well known in the art.

Flanking each side of the brush at the bottom of the casing are supports l3 extending from close 65 to the brush to the front and rear walls of the Fig. 1 is a perspective view of a carpet sweeper casing. These supports may be tilting dust pans commonly found in sweepers of this type or may be fixed debris-retaining or non-debris-retaining.

Supported by the supports l3 are pan-shaped receptacles A, A made of paper or other light 5 flexible and cheap material and connected between the upper ends of their outside walls by the same material.

Conveniently my debris receptacle is formed from a paper blank comprising the middle connecting portion I5, the outside walls l6, Hi, the bottoms IT, II, the inner walls l8, t8, the end Walls formed by overlapping a flap IE carried by the outside walls, a flap ll carried by the bottom and a flap l8 carried by the inside walls, these various parts being defined by fold lines as indicated in Fig. 4.

Secured to each inside wall, preferably near each end wall, are the two ends of a string IS, the middle of which overlies portion l5 and passes through perforations 20 which may be conveniently defined by eyelets to avoid tearing.

The paper pans, when in place within the casing, rest upon or in the supports I3 in position to receive the sweepings discharged by the brush, while the intermediate connecting portion l5 of the structure overlies the open mouths of the pans and the intermediate brush.

If desired, casing [2 may be provided with a readily movable or removable cover to overlie the disposable debris receptacle described above.

In use the pans of the disposable (or removable) debris receptacle, will receive and retain the brush sweepings. In due course the user, grasping the middles of the strings l9, may lift the disposable structure bodily from the casing, the pan structures swinging on the fold lines between the outside walls and the connector I5 until the upper edges of their inner walls engage the under face of connector l5 thereby entrapping the contents of the pans so that spilling is impossible.

Because of the low cost of this disposable structure it may, when changed and removed, be conveniently thrown into the garbage, or incinerator, or furnace, though economically inclined persons may dump the contents and re-insert in the sweeper casing.

I claim as my invention:

, 1. For a carpet sweeper of the rotary brush type 5 and having substantially horizontal platforms flanking the brush below the center thereof, a removable debris receptacle formed of flimsy, inexpensive, readily discardable material and comprising, a pair of parallel pan-like receptacles capable of flanking the sweeper brush and restable on the brush-flanking platforms of the sweeper, a readily flexible connector overlying and connecting said receptacles, and means cooperating with said receptacles and operable, upon removal of said receptacles from said sweeper, to close said pan-like receptacles against accidental discharge of dirt therefrom.

2. For a carpet sweeper of the rotary brush type 1 and having substantially horizontal platforms flanking the brush below the center thereof, a

removable debris receptacle formed of flimsy, inexpensive, readily discardable material comprising, a pair of parallel pan-like receptacles capable 15 of flanking the sweeper brush and restable on the wherein 'the lifting means comprise flexible elements passed through the connector and attached to the pans at points inwardly spaced from the connections of the pans with the connector. l GEORGE M. PARKER.
