- FIG. 8 is a wiring diagram showing the circuitry of the device shown in the preceding figures.
- reference character it designates generally the combined carpet sweeper and vacuum cleaner nozzle. it includes a base member 12, which preferably is a die casting. One longitudinal edge of the base member 12 is formed as a tunnel 1 1- within which is rotatably mounted a cylindrical brush member 16. The rear wall of the tunnel 14 is formed with an opening 1 .3, shown in FlGS. 3 and 4, which communicates with a dirt receiving compartment 24) formed in the base member 12. Compartment 24B is formed with an open bottom which, however, is normally closed by means of a pivoted cover member 22.
- Base member 112 is formed with a pasageway 24 shown Patented May 25, 1965 'ice in FIG. 3 which communicates with the center of dirt receiving compartment 2t) and extends backwardly therefrom to a semi-circular seat formed in the base member.
- a coupling member 2 5 having a cylindrical end portion is pivotally mounted on the semi-cylindrical seat and is secured in place by means of a cap member 32 which is likewise formed with a semi-cylindrical seat.
- a preferably rigid hollow member 3 is secured to coupling n1ember 26 and consequently may be pivoted with respect to the base member and associated parts while remaining in communication with passageway 24.
- the lower surface of base member 12 is covered by a surface contacting plate secured to the base member by screws 27.
- This plate is formed with an elongated opening 29 in line with the open bottom of compartment 2t) and which is normally occupied by the pivoted cover member 22.
- Plate 25 is also formed with an elongated opening 31 in line with tunnel 14 and brush 1d, the bristles of the latter extending through opening 31 so as to contact and sweep over the surface eing cleaned.
- a number of bridges 33 extend across opening 31 to prevent a rug or the like from being drawn too far into the opening when the device is used as a suction nozzle.
- an opening 35 may be provided in plate 25 through which projects a roller 37 which is rotatably mounted in base member 12 and serves to support the rear edge of the device, particularly when it is used on a hard surface.
- a low voltage direct current electric motor 36 is mounted on the upper surface of base member 12 behind the dirt receiving compartment 29 and to one side of the coupling member 26.
- a flexible belt 38 driven by the motor 36 engages a pulley dtl mounted on the shaft of brush to so as to rotate the latter.
- a rechargeable storage battery 42 is removably mounted by means of a strap 4-3 on the upper surface of base member 12 behind the dirt compartment 4d and on the opposite side of coupling member 26 from the electric motor. Also mounted in this space are a step-down transformer 44, a resistor and a full wave rectifier 48, the electrical connection of which are shown in detail in FIG. 8.
- the motor, storage battery, transformer, resistor and r ctifier are enclosed by means of a hood member which is secured to the base member 12 in any suitable manner and is provided with an opening 52 through which the coupling member 26 extends.
- portion 54 of the hood member which is over the storage battery 42 is connected to the remainder of the hood member by means of a hinge so that it may be readily pivoted to the position shown in FIG. 7 so as to expose the battery 42 in the event it is necessary to replace the latter.
- the primary winding 53 of the transformer 44- is supplied with normal house current at 120 volts and cycles through a pair of conductors 6d.
- the secondary winding 62 of the transformer is provided with a center tap which is connected by means of a conductor 64 to one terminal of the resistor t6, the other terminal being connected to one side of the battery 42.
- the other side of the battery is connected by conductors as and 63 to the opposite terminals of secondary so, the rectifiers 4-3 being interposed in these conductors so as to provide full wave rectification.
- the pair of conductors 60 which supply the primary of the transformer are incorporated in an electric cord which extends along the handle 34-, preferably through a channel St) formed on the exterior of the handle.
- the cord 60 may be provided with an electric plug 32 which may be connected to a suitable receptacle on the exterior of a flexible hose 84 which extends from the upper end of hollow handle 34 to the inlet of an electric vacuum cleaner 86, and the hose carries suitable electric conductors which may be connected in well known manner to the electric circuit of the vacuum cleaner, which includes a cord 88 adapted to be plugged into any suitable outlet.
- a plug or stopper 9% is preferably secured to the upper end of the handle 34 by means of a flexible strap or chain 92 and may be inserted into the upper end of the handle when the hose 84 is disconnected therefrom.
- the plug 90 is placed in the upper end of the handle 34 and the switch shown in FIG. 8 is thrown to the right-hand position, thus supplying the motor 36 with direct current from the battery 32. Operation of the motor rotates the brush l6 and if the device is moved by the handle over a surface of a rug or the like, the rotating brush sweeps surface dirt and other litter therefrom through the openings 31 and 18 into the dirt receiving compartment 20, where it is retained in the manner usual with carpet sweepers.
- the plug ht) prevents any dirt or dust from escaping through the hollow handle.
- the dirt may be removed from the compartment 2th by holding the device over a suitable receptacle and pivoting the cover member 22 to open position, thus permitting the dirt to fall out the now open bottom of the dirt receiving compartment.
- the dirt may be allowed to remain within the compartment to be removed therefrom by airflow when the device is next used as a vacuum cleaner nozzle. This is accomplished by removing the plug W and connecting the hose 84 to the upper end of the handle 34 and by connecting the electric plug 32 to the receptacle on the hose 84.
- air is caused to enter the compartment 20 through the openings 31 and 18 and to leave through the passageway 24 leading to the coupling member 26 and hollow handle 34. This flow of air picks up any dirt which may be in the dirt receiving compartment 2%
- the supply of electric current through the conductor 60 energizes the transformer i4 and causes a low voltage alternating current to appear at the terminals of the secondary winding 62.
- This alternating current is rectified by the rectifiers 4-8 and if the switch 74 is thrown to the left-hand position, the motor 3:6 is supplied with low voltage rectified current, while at the same time this rectified current is supplied to the battery through the resistor 46 so as to recharge the battery during the time the device is used as a suction nozzle.
- Operation of the motor rotates the brush 16 as previously described, and the brush aids the stream of air in removing dirt from the surface being cleaned, and this dirt is carried along through the compartment 2% and the passageway 24 to the hollow handle 34 and thence through the hose 84 to the vacuum cleaner.
- the plug 82 may be connected directly to any 120 volt outlet while the device is stored, in this case the switch 74 being in its open position. Under these conditions rectified low voltage direct current will be supplied through the resistor 46 to recharge the battery, but the motor 36 will not operate.
- a device which may be used as an electric carpet sweeper which is particularly adapted for quick clean up jobs, and which also may be used as a power nozzle in conjunction with a vacuum cleaner for a more thorough and extensive cleaning using both the sweeping action of the brush and the cleaning action of the air.
- the battery Under normal conditions of use the battery will be kept charged automatically and without conscious attention on the part of the operator due to the fact that it is recharged whenever the device is used as a vacuum cleaner nozzle.
