DISPOSABLE DUST RECEPTACLE FOR BRUSH TYPE CARPET SWEEPERS

Claims.

In that type of carpet sweeper characterized by a rotary brush rotatably mounted within a casing supported by traction wheels which permit reciprocating transportation of the casing at ® right angles to the brush axis accompanied by brush rotation, dirt-receiving pans are arranged within the casing, one along each side of the brush in position to receive and retain the sweep1 n ’^ngS- ®^enerapy these pans are tiltable about axes parallel with the brush axis to discharge accumulated sweepings.

Disposal of debris from sweepers of this type is a somewhat mussy operation and, in many instances, 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 °f scattering of some of the debris during the 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:

•m ^Fig’ ^{1 is a perspective view} a carpet sweeper 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 10, 10 indicate usual traction ⁴⁰ wheels between which is mounted the rotary brush driven by said wheels. The wheels support a casing 12 which envelopes the brush, and which is substantially like casings ordinarily found in ₄„ sweepers of this type but differs therefrom in that ⁰ it has no fixed top overlying the brush and adjacent regions 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 13 extending from close 65 to the brush to the front and rear walls of the (CI. 15—41) 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 13 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 con- 10 necting portion 15, the outside walls IS, 16, the bottoms 17, 17, the inner walls 18, 18, the end walls formed by overlapping a flap 16' carried by the outside walls, a flap 17' carried by the bottom and a flap 18' carried by the inside walls, these 15 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 19, the middle of which overlies portion 15 and passes ²⁰through 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 13 in position to receive the sweepings discharged by the brush, ²⁵while the intermediate connecting portion 15 of the structure overlies the open mouths of the pans and the intermediate brush.

If desired, casing 12 may be provided with a readily movable or removable cover 25 to overlie ³⁰the 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 19, may lift the disposable ³³structure bodily from the casing, the pan structures swinging on the fold lines between the outside walls and the connector 15 until the upper edges of their inner walls engage the under face of connector 15 thereby entrapping the contents ⁴⁰of 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 ⁴may dump the contents and re-insert in the sweeper casing.
