5 Claims.

The invention relates to vacuum cleaners of the portable type and more particularly to a cleaner provided with two suction nozzles each having a motor driven brush therein.

Vacuum cleaners of the motor driven brush type now in general use are provided with a single suction nozzle having a brush therein arranged to be continuously driven in one direction only during the operation of the motor. Thus as the 1 cleaner is moved to and fro upon the objective surface, the motor driven brush in the nozzle thereof continues to rotate in one direction regardless of whether the cleaner is moving forward or backward. From this it will be seen that the maximum cleaning effect of the motor driven brush is obtained only about one-half of the time the cleaner is in operation.

A principal object of the present improvement is to provide a vacuum cleaner having two suction nozzles with a motor driven brush in each nozzle, the brushes being driven in opposite directions,

" whereby the maximum cleaning effect of one brush is being obtained at all times regardless of the direction in which the cleaner is being moved upon the floor.

Other objects which will be later pointed out or which will appear from the disclosure in the drawings and the following description may be attained by constructing the improved vacuum cleaner in the manner illustrated in the accompanying drawings, in which Figure l is a side elevation of the vacuum cleaner embodying the invention;

Fig. 2, a top plan view of the same;

Fig. 3, a longitudinal sectional elevation; and

Fig. 4, a fragmentary detail elevation of the handle of the cleaner.

Similar numerals refer to similar parts throughout the drawings.

The improved vacuum cleaner may be of the vertical motor type of portable cleaner including an electric motor 10 mounted upon a fan housing 11 within which is located a suction fan 12 fixed upon the shaft 13 of the motor. A suction chamber 14 communicates with the underside of the .fan housing through the opening 15 and is provided at opposite ends with the suction nozzles Rotary brushes 20 and 28a are mounted in the nozzles 16 and 16a respectively, being journaled upon the shafts 21 supported in the end walls of said nozzles. Each of the brushes 20 and 20a is provided with a pulley 22, a belt connecting each 63 of said pulleys with one of the pulleys23 upon the motor shaft 13, located within the suction chamber 14.

Assuming the motor shaft 13 to be rotating in the direction of the arrow shown in Fig. 3, it will be seen that the brushes 20 and 20a will thus be rotated in opposite directions as indicated by the arrows thereon in said figure.

The outlet neck 24, of the fan chamber, extends outwardly to one side thereof substantially at the center of the cleaner and has swivelled thereon a coupling 25 to which is connected the dust collector bag 26 as by the connector member 27 which may be of any usual and well known construction. The upper or larger end of the bag may be supported from the handle 28 as by the strap 29 in usual and well known manner.

The handle 28 may be connected to the cleaner as by the usual bifurcated member 30, one arm 31 thereof being pivotally connected to the fanzles 16-or 16a in front as desired. By swinging the handle 28 upon its pivot, the swivelled coupling 25 will be turned upon the outlet neck 24 of the fan casing, swinging the dust collector bag from the full line to the broken line position shown in Fig. 1 .or vice versa.

The handle 28 may be provided with a spade grip 35 as shown in Figs. 1 and 4, the same being swivelled upon the upper end of the handle and provided with a spring pressed thumb lever 36 adapted to engage in the notches 37 formed in the annularflange 38 fixed upon the handle 28. The spade grip may thus be turned to any desired position and held in adjusted position.

As shown in Figs. 2 and 3, the handle may if desired be provided with a piston grip 39 instead of the spade grip above described and a rod 40 may be located through the handle, the upper end thereof being provided with a knob 41 located adjacent to the piston grip 39 and adaptedto be grasped by the finger to operate said rod. This rod protrudes through the lower end of the handle and is provided with a pawl 42 adapted to be received in the notch 43 of the sector 44 in order to hold the handle in up- 1 0 switch and the motor when not in use. A spring 45 normally urge-the pawl 42 toward the connection between said in each case being the same as in ordinary practice.

I claim:

A vacuum cleaner including a casing adapted to be moved to and fro upon an objective surface, a handle having a pivotal connection with the'handle for starting and ed to be moved to and fro upon an objective surface, a coupling swivelledupon one side of the casing, a dust collector bag connected at one end being connected to said handle.

4. A vacuum cleaner including a fan walls forming a suction chamber adjacent therein opposite directions.
