Disposed in the fan chamber i8 is a fan 730w w and is connected to a pulley rigidly 22 mounted on the armature shaft of a motor attached to the motor armature shaft for rotatenclosed in a housing 23 which is supported on the brush brackets 2 only one of which is shown, in the In Operation, it is desired employ the casing The brackets 24 space t housing cleaner in the usual'manner, that 1s, moving the passageway it and-the top wall (if the casing za the casing M form an annular space cleaner nozzle H forwardly and rearwardly over 25 therebetween which communicates with a dirt the f ce to e cleaned, the sprin le er M is bag-26 removably tt t th n of th depressed and the nozzle H rotated until the latcasing it by a bracket 21. The cleaner i mater is transverse to the cleaner body or motor I nipulated by a carrying handle 28 attached to armature, as wn in Figures 3 and The the. cleaner body it by suitable means such as p g biased lever ttwill engage the slot 46 and screws 29. A switchtt is positioned in the banlocks the nozzle rig d y th pect to the cleaner die 28 and is connected to the motor by unshown body It. In this position of the nozzle, the belt conductors and to a source of electric current 49 has a quarter turn and upon energizing the byineans of a cord 3| secured to the rear of motor it rotates the brush 48 to loosen the cmthe handle 28.

If it is desired to employ the cleaner in confined places, as for example in comers, the lever 42 is depressed and the nozzle rotated 90 degrees to the position shown in Figures 1 and 2, and the spring biased lever 42 engages the slot 45 to lock the nozzle in position. In this position of the nozzle, the flared end 5| thereof extends below the cleaner body It, as shown in Figure 1, so as not to materially unbalance the cleaner, whereby the operator may easily move the cleaner from side to side and, if desired, forwardly and rearwardly to remove dirt from the surface'bein cleaned.

I claim:

1. A'suction cleaner comprising a body, a noz- -zle mounted at one end of said body for movement to difierent adjusted positions, a fan chamher in said body and having an inlet communieating with said nozzle, a motor for driving a fan i in said fan chamber and having its driving shaft ,extending through said fan chamber inlet, a brush rotatably mounted in said nozzle for engagement with the surface to be cleaned, a, belt connected to said extended shaft and said brush to rotate the latter, said nozzle being movable to adjusted positions parallel or transverse to said shaft, and said belt operating to rotate said brush in'said adjusted positions with respect to said shaft;

2. A suction cleaner comprising a body, a nozzle mounted on said body for movement to different adjusted positions, a fan chamber in said body and having an inlet communicating with said nozzle, a motor having a shaft for driving a fan in said fan chamber and having its driv ing shaft extending through said fan chamber inlet, a brush rotatably mounted in said nozzle for engagement with the surface to be cleaned and movable with said nozzle when the latter is moved to said different adjusted positions, and a belt connected to said extended shaft and said brush to rotate the latter, said belt being without twists when said nozzle and its brush are in' one adjusted position, said belt being so arranged between said extended shaft and brush that movement of said nozzle normal to said one adjusted position and parallel to said motor shaft places a quarter-turn twist in said belt between said extended shaft and said brush, said belt operating to rotate said brush in anyadjusted position of said nozzle with respect to said body.
