DUSTPAN CONTROL MEANS FOR CARPET SWEEPERS Filed Jan. 8, 1932 INVENTOR ATTORNEYS Patented Nov. 7, 1933 IDUSTPAN CONTROL MEANS FOR CARPET SWEEPERS Fred W. Pullen, Grand Rapids, Mich assignor to Bissell Carpet Sweeper (30., Grand Rapids,

Mich.

Application January 8, 1932. Serial No. 585,423

6 Claims.

The objects of the invention are:

First, to provide such a structure which is very compact, not liable to obstruction, and avoids accumulations of dust.

Second, to provide such a structure with a minimum of parts.

Third, to provide such a structure which admits of a very low construction of carpet sweeper.

Fourth, to provide such a structure in which the actuating lever can be readily manufactured by deforming a rod or heavy wire.

Fifth, to provide improved means of pivoting such a lever.

Further objects and objects pertaining to details and economies will appear from the description to follow. A preferred embodiment of my invention is illustrated in the accompanying drawing, in which:

Fig. 1 is a transverse detail sectional elevation view through a carpet sweeper embodying the features of my invention, showing the pivoted dustpan, the connecting spring, and the spring actuating lever.

Fig. 2 is an enlarged detail sectional plan view taken on line 22 of Fig. 1 through the carpet sweeper case end and the pivot means for the actuating lever, the lever being shown in full lines, and the retaining bushing clip being shown in section and the retaining stop nail in full lines.

Fig. 3 is an enlarged detail elevation view of the inner exposed portion of the lever showing the method of engagement with the dustpan spring and the relation of the retaining bushing clip.

Fig. 4 is a detail view of the parts in separated relation, only a fragment of the carpet sweeper case being shown.

Fig. 5 is a detail perspective view of the bushing clip for the lever journal.

Fig. 6 is an enlarged plan view of the lever, indicating by dotted lines how the same is formed from a round rod or wire.

The parts will be identified by their numerals of reference which are the same in all the views.

1 is the end of a carpet sweeper case, having the convex top 2 and the sides 3. 4, 4 are the dustpans which are pivoted at 41, 41 in the usual manner. 5 is a the A-shaped spring engaging the dustpans at 51 at their inner downwardly projecting corners and connecting the same together. The upper central part of the the dustpans are in closed position. The dustpans are opened by elevating the center of the spring which is a usual action with such spring structures.

My invention pertains particularly to the lever means by which this is accomplished. The lever 6 is formed of a single rod or heavy wire having an offset central partition pivot 61 disposed through a slightly enlarged aperture 11 in the case end. The aperture 11 is larger than the pin and I provide a clip '7 with an inwardly projecting bushing bearing part 72. This is retained in. place by the nail 8 which is driven through and projects into the inside of the case and serves as a stop 81 for the inner end of the lever. The wire or rod of the outer portion 62 of the lever is flattened so that it is like a vertical blade, stifiening the same very materially. The finger piece 63 is formed by ofisetting a portion of the same. A portion of the lever 64. terminates in finger 65 which is stiffened and supported by the flattened portion 66, see Fig. 6. This lever 6 is installed by inserting the end 65 through aperture 11 in the side of the case and then manipulating the lever to hook it through and then repeating this manipulation at the offset central pivot part 61. The clip -7 with its inwardly projecting bushing part 72 is then inserted as seen in Fig. 2, closely embracing the pivot 61, as indicated above.

In operation it will be noted that by depressing the finger portion by pressure on the finger portion 63 the central portion of spring 5 will be raised which will cause the dustpans to be opened. When the lever is released, the action of the spring closes the dustpan and carries the lever down against the stop 81. The lever is substantially a straight lever and of such shape that it projects very little, if at all, above the top of the case, and is disposed close to the end of the same. I desire to claim the combination specifically as shown and also the particular construction of the lever.

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

1. In a carpet sweeper, the combination of pivoted dustpans, an A-shaped spring connecting the same, a lever made of a rod having an offset central pivot portion, the outer portion of the lever being flattened to stiffen the same, and the inner portion being provided with an inwardly projecting lug to engage the said spring, the pivot portion being disposed in an aperture in the end of the case, a retainer bushing clip to fill the aperture bearing around the said pivot, having a laterally projecting ear, and a nail disposed through said ear and extending within the case to form a stop for the lever.

2. In a carpet sweeper, the combination of pivoted dustpans, an A-shaped spring connecting the same, a lever made of a rod having an ofiset central pivot portion, the inner portion being provided with an inwardly projecting lug to engage the said spring, the pivot portion being disposed in an aperture in the end of the case, a retainer bushing clip to fill the aperture bearing around the said pivot, having a laterally projecting ear, and a nail disposed through said ear and extending within the case to form a stop for the lever.

3. In a carpet sweeper, the combination of pivoted dustpans, an A-shaped spring connecting the same, a lever made of a rod having an offset central pivot portion, the inner portion being provided with an inwardly projecting lug to engage the said spring, the pivot portion being disposed in an aperture in the end of the case, and a retainer bushing clip to fill the aperture bearing around the said pivot, having a laterally projecting ear.

4. In a carpet sweeper, the combination of pivoted dustpans, an A-shaped spring connecting the same, a lever made of a rod having an offset central pivot portion, the inner portion being provided with an inwardly projecting lug to engage the said spring, the pivot portion being disposed in an aperture in the end of the case, and a bushing means in said aperture.

5. A lever adapted for carpet sweepers of the type having pivoted dustpans held by a connecting spring near an end of the case, said lever being made of a rod and having an offset central pivot portion, one end being flattened to stiffen the same and the other end being provided with a projecting lug parallel to the pivot portion, the pivot portion being adapted to extend through said end of the case and the lug being adapted to engage said holding spring.

6. In a carpet sweeper, the combination of pivoted dustpans, means holding said dustpans yieldingly in place, and a lever made of a rod having an offset central pivot portion, the inner portion being provided with an inwardly projecting lug to actuate said dust pans, the pivot portion being disposed in an aperture in the end of the case.
