[All

rial, is secured to the back portion of each brush and extends outwardly well toward the ends of the tufts or bristles'of the brush vtion for carpet sweepers are supported on pivots 24 in the ends of the case, and are adapted to close up against the sides 7, as clearly appears in Fig. II. These are controlled by links 28-28, which are connected by ivots 31 to the hand-lever 29,.which-is fulcrumed at 30in the end of the case, so that the dust-pan can be readily dumped. The outer edges of the dust-panfitinto recesses 25 in the sides 7 of the case.

A flexible apron 26 is provided on each dust-pan 23, to which is secured a rigid bar 27, formed preferably of a fold of sheet metal. This bar drags along the floor and the apron affords a very effective incline surface for the dust and dirt that is swept by the brush thus readily collected and passed up into the pans. As this apron is flexible and is weighted, it rests very close to the floor and the operation of the device is exceedingly effective. The collector at the rear folds back under the pan, making a tight joint and compelling the air to circulate out through and above the pans. Wire screens 33, with fabric linings 33 are covered-over windows or openings in the sides 7 of the case above the dust pans and permit the air to readily circulate therethrough and collect the dust which drops down into the dust pans 23. f

A-handle 34, with a suitable bail connection 35, withvpivot pins 36, 'is provided for manipulation of the sweeper. This bail is held in central position by the balancing springs 37-37, which are connected from opposite sides of the case. See Fig. I.

I have shown my improved structure in its referred form. The spiral flat brushes, wit flexible backings, secure a very effece tive sweeping action, which eoaets effectively with the dust collectors 26, but these dust collectors would also be effective with other styles of brushes. I know from observation and test that the weight bars 27 might be omitted and the device would 0 erate quite eflectively, though the weig t bars are of decided advantage. The parthat the sweeper so that the dirt and dust is ticular construction I have adopted enables the application of the spring pressure very effectively, as I have indicated, and this means would likely be valuable in other kinds and styles of sweepers.

The dust pans and their dumping means can be of any desired form, the form I have shown being slightly modified from the standard construction of carpet sweepers. It is of advantage that the brush sections be adjustable on the radial arms, but it is clear would be effective for a long time if this adjustable feature was not incorporated in the sweeper.

In Figs. V and VI, I show a in which the brush members, in place of being spiral, are straight, like the blades of a fan in a fanning mill. This makes an effective structure, butit' is not nearly so effective as the spiral-arrangement, and is slightly irregular in its operation.

I desire to claim the. invention in the specific form in which I have illustrated it because I believe the parts coact, but I also desire to claim the combination broadly, and also to claim the various novel sub-combinations which are present in the structure.

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 with a suitable case with a central openinlg1 .in. the end and screened apertures at eac side; a skeleton fan 'brush, the blades of which are of spiral'form,

with its axis lengthwise of said case; drivin traction wheels suitably connected to 'drive the said brush; and dust pans supported in the lower part of said case beneath the screened openings in the sides of the case to receive the dust collected by said fan brush.

2. In a carpet sweeper, the combination with a suitable case with a central opening in the end and screened apertures at each side; a skeleton fan brush centrally disposed with its axis lengthwise of said case; dnving traction wheels suitably connected to drive the said brush; and dust pans supported in the lower part. of said case beneath the screened openings in the sides of the case to receive the dust collected by said fan brush.

3. In a carpet sweeper, the combination of a suitable case; a rotatable brush therein; traction driving wheels for actuating the said brush; a pivoted dustl pan su ported in the lower part-of said case and disposed to receive the dust collected by said brush; flexible dust aprons secured to said dust pans on the sides toward the brush and disposed to contact with the floor beneath and to coact with said brush, as specified.

4. In a carpet sweeper, the combination of centrally disposed a suitable case; a rotatable brush therein; traction and drivin wheels for actuating the'said brush; suita 1e axles on'which said driving Wheels revolve, disposed in suitable 5 slots at the ends of the case; spring pressure bolts connected to the centers of said axles and supported on the sides of the case for putting tension thereon; oblique springs connected to said axles toward each end and 10 disposed to draw the same inwardly; and

suitable dust as specified.

In witness whereof,

pans for collecting the dust,

I have hereunto set my hand and seal in the presence oftwo Witnesses.
