UNITED STATE THOMAS H. BELT. AND JOHN o. SOHOENLEBER, onNEw YORK, N. Y., AssIGNORs To BELL scHOENLEBnn MANUFACTURING co'. INC., .a CORPORATION OF NEW YORK.

SWEEPER;

' application med Maren 24, '1921.' serial No. 455,349.

To all whom t ma concern:-

Be it known t at we, ,fIHoMAs H. ELL

and JOHN G. ScHonNmBnR, citizens of the United States, residing at New York, in the county of New York and State of New York,

have invented certain new and-useful Improvements in Sweepers, of which the followingis a s ecification.

This inventlon relates to ioor and carpet 'l0 sweepers, and more particularly to an im` y character which will contain a central removable dust collector arranged between the sweeping brushes in a manner that will cause a more effective operation of the apparatus.

Other objects of the invention will appear upon consideration of the following detail description and accompanying drawings,

Figure 1 .is a transverse section taken through the device showing our improvement applied to the sweeper. l 4

Figure 2 is a cross section taken approxi'- mately on the line 2-21of Fig. 1, p

Figure 3 is a detail perspective view ofthe dust collecting element. .i

l Referring to the drawing by numerals, the .housing '1 may be of any preferred construction a d is provided on its top with a chamber 2 ithin which a motor may be mounted for connection to a fan shaft A3 which'has mounted thereon a suction fan 4 operable in a horizontal position whereby the 'blades will tend to draw rthe dust and dirt upwardly into the fan chamber 5 through an opening 6 in the lower wall of the fan chamber as shown to`advanta in Fig. 1. A s out or 5o nozzle 7 projects om the fan cham er and may be connected in any convenient mannerv to a bag or receptacle for receiving the dust and dirt.'

The bottom wall ofthe housing lis p ce vided with two longitudinal openings 8 and above these openings horizontal shafts 9 are provided upon-which brush rollers 10 are arranged. The brush rollers 10 are provided with the bristles 11 and each end of each4 shaft 9 is provided with traction rollers 12 which are adapted to engage the floor so that rotary motion will be imparted to the brush rollers when the traction rollers are moved across the surface of the-door.-

Disposed centrally within the housing 1 and located between the brushes is a dust collector shown in detail in Fig. 3 and indicated at 13. This is a yremovable element which is mounted in the housing 1 and projects from one end to the other'thereof and has its sidewalls curved as indicated at 14, whereby the curvature will conform to the path of the bristles 11 ofthe brush element when the brushes are in operation. The top of the dust collector is provided with a longitudinal channel or groove 15 which serves as a receptacle for a quantity of the dust and dirt while the device is in operation. This receptacle 15 is located directly below the opening 6 and below the fan in the fan chamber so that the tendency of the fan yvill be to draw the dust upwardly through the opening 6 but will permit a quantity of dirt to collect inthe longitudinal channel 15.

In operation, the device will be moved across the surface'of the floor or carpet and the traction rollers will, by virtue 'of theii` rotary movement, im art `rotaryimovement to the brush rollers w ereby the bristles will engage the surface of the floor to thorou hly sweep and clean the same. The dust wi l be deposited in the channel 15 of the dust collector and thesuction fan will be operated Iby the motonto draw the dust and eject it through the nozzle 7 where it will be re- 95 ceived in a bag or receptacle as is well known in the art.

Minor changes may be made in the details of construction without departing from the s iritof the invention or the scope of the nc aimsl hereunto appended.`

1. In sweeping apparatus of the class described, the combination of a housing, spaced parallel brush rollers in said housing, a dust collectorv removably mounted between the brush rollers having. its opposite sides concaved, said dust collector having on its top a longitudinal channel to act as a dust receptacle, and a. suction fan arranged above the 11o dust 'collector `to withdraw the dust from said receptacle.

2. In a sweeping ap aratus of the character described, thecom inationof a housing, spaced parallel brush rollers in said housing, a chamber positioned on said housing, an

electric motor in said chamber, said housing having a depression formed in the top thereof, a fan in said depression to be operated by said electric motor in said chamber, a dust collector removably mounted between the brush rollers, the side walls of said dust collector being concaved and having a longitudinal channel formed on its top surface for receiving the dust, and said housing being 15 In testimony whereof, we have affixed our 20 signatures in the resence of two witnesses.
