ments may be connected to thefan of the cleaner for off-the-floor cleaning. 7 1

Another object ofthe invention is to provide a vacuum cleaner of the type having a surface cleaning nozzle'with a power driven agitator or brush associated therewith, with a built-in" converter by means of which attachments may be readily connected with and disconnected from the cleaner and which at the same time functions to disconnect the agitator or brush associated with the floor nozzle from the driving motor of the vacuum cleaner and to shut off the communication between the floor nozzle and the fan of the vacuum cleaner.

Other objects and advantages of the invention will be apparent from a consideration of the following specification taken in conjunction with the accompanying drawing, of which there is one sheet and wherein: I

Fig. l is airagmentary vertical sectional view through a floor type cleaner embodying the invention; and

Fig. 2 is a fragmentary cross section taken 'along the staggered line 2-2 of Fig. 1, looking in' the direction of the arrows.

A vacuum cleaner embodying my invention may comprise a casing or housing l adapted to be supported for movement over a floor and having an electric motor l2, a suction creating means l4 comprising a fan l6 arranged in the fan chamber l8, a floor nozzle 20 having a rotary brush or agitator 22 operatively associated therewith. The casing is supported for movement over a floor so that the nozzle may be spaced a desired distance from the surface being cleaned, and tin operation the motor I2 driving the fan l6 will induce a flow of dirt-laden air upwardly and inwardly through the nozzle 22 and fan chamber l8 to a suitable dirt-collecting receptacle which may be attached to the cleaner in any conventional manner.

The brush or agitator 22 may, as illustrated, be arranged within the mouth of the nozzle 20 and supported for rotary movement on a horizontal axis. The brush 22 may be provided with bristles for engaging the material being cleaned to aid in dislodging dirt therefrom which is carried by the stream of dirt-laden air which socket 30.

flows inwardly through the-nozzle as previously described.

The fan l6 may be supported upon and driven by a shaft 24 of the motor I2, and the shaft may be formed to extend into the upper part of the nozzle Zilabove the brush 22. A belt'26 passing over the end of the shaft 24 and a pulley 24 formed on the brush 22 is adapted 'to rotate the,

brush 22 about its horizontal axis when the motor I2 is operated. In the drawing the belt is illustrated as being disengaged from the shaft 24 by means of a -beltlifting device, the function of which will appear hereinafter.

Above the nozzle 20 the casing-may be provided with a socket 30 adapted to receive the end 32 of a coupling member 34 to which a flexible' hose may be swiveled. If desired, a latch may be provided for preventing the accidental separation of the coupling member 24 and the The end 32 of the coupling member 34 is cut away at 36 on one side thereof to communicate-with a port 38 formedin the upper part of the nozzle and providing communication between the interior of the socket and the 25 interior of the nozzle 20. The port as is adapted to be closed by a valve 40, but is illustrated in Fig. l as being open. The valve 40 may comprise a cup-shaped member having a portion of it cylindrical wall cut away to provide an opening which is adapted to register with either the port 38 or with another port 42 as hereinafter described.

The valve 40 is mounted for rotary movement in the nozzle 20 and is provided with an opening through which the end of the shaft 24 e1 tends. The valve is positioned in the nozzle 20 at what may be termed the fan eye which normally provides communication between'th'e interior of the nozzle 20 and the fan chamber l8. However, in the position in which the parts are illustrated in Fig. -1, the interior of the coupling member 34 is connected through port 22 and the fan eye 44 to the fan chamber. I! so 45 that upon operation of the fan a flow of air will be induced through the coupling member 34,

port 38, into the fan chamber and thence into a suitable dust receptacle.

The port 42 is formed by an opening in part of the wall of the nozzle 20 and whenthe valve 40 is positioned 180 from that in which it is shown in Fig. 1, the port 42 and the valve opening 40 will establish communication between the interior of th nozzle 20 and the ian chamber is.

When the valve 40 is rotated from the position illustrated in Fig. 1, the valve body will close the port 38 and open the port 42. A finger 4| affixed to the outside of the valve body- 40 is adapted to lie parallel to the axis of the shaft' tions of the upper and lower knobs 52, the member 48 engaging the sides of the end 4 of the finger 45 will rotate the valve 40 about its axis which coincides with that of the shaft thereby shifting the finger 45 from the position shown in full lines to the position shown in dot and dash lines in the drawing. When the ilnger 45 so moves the belt 26 will be recngagedwith the end of the shaft 24 and since movement of the finger 45 will move the valve 40 180, the port It will beclosed and the port 4! opened thereby operatively connecting the brush 2! to the motor of the cleaner for driving the same and reestablishing the communication between the floor nozzle 20 and the fan chamber 18.

When the finger 45 is in the position shown in full lines in the drawing, the motor will be employed only for driving the fan It for the purpose of inducing a flow of air into the fan chamber through the port 38 and the coupling 34 to which various, types or cleaning tools maybe attached. "However, when the valve 4011s shifted as previously described to open the port 42, the coupling member 34 may be disconnected-and the machine will be ready, for what may be termed floor or surface cleaning.

A'hinged cover 58 pivotally secured by a pivot ii to the casing lfl may support a light 62 and is adapted to cover the socket 30 when the coupling member 34 is detached from the machine. The

space enclosed by the cover 58 provides a receptacle Open at the front for the light 62.
