HAND VACUUM CLEANER.

Application inea December 3o, 1924. serial No. 758,823.

Uur invention relates to an improvement in hand vacuum cleaners. The object is to provide a portable vacuum cleaner sufliciently light in Weight so that it can be easily held in the operators hand, and moved about without undue exertion; and our real aim is to provide a device that can be operated from the currentA of a car and utilized for cleaningclosed cars. It is, however,'obvious that its application is of a far wider range, and that it may be used for cleaning upholstered furniture, draperies, mattresses, and the like by aplugging into `the house current.

In the accompanying drawings:

Fig.- 1 is a side elevation;

Fig. 2 is a transverse section showing the suction-chamber and fan; v

Fig. 3 is a longitudinal section; and

Fig. 4 is a front view of the nozzle partly broken away.

A, is the casing.' 'Ihe easing is divided transversely by partition 1 into the motor Q .chamber 2, which contains the motor 3 and the suction chamber 4. The current is conducted to the motor through the lead-Wire 5,

passing through the handle. 6. Armature ,shaft 7 from the motor extends through a bearing 8 in the center of the partition 1 into the suction chamber 4, and on this protruding end of thearmature shaft the suction fan 9'is secured by set-screw 10, or other means. The numeral 12 represents the nozzle. This is removably attached to 35 the casing A upon which it is held by frictional engagement or other attachment. A

The dust sucked in through the nozzle 12 is discharged through a spout 13 into a bag 14, which is removably supported on the simple means of spout by collar 15. and supported near its outer end by a flexible device 16.

The casing isremovably held on the base 17 of the device by bolts 18 and nuts v19.

The current is turned on and off by the switch 20 preferably located at some point on the handle.

A Vsingle roller 21 is rotatably supported by a bracket 22, preferably formed integral with the base 17 of the device.

Partitions 23 may be formed in the nozzle, if desired, to equalize the suction upon the surface being cleaned.

To gain access to the set-screw 10, a hole 24 is provided in'the casing, and a lid 25 held by a pivot 26 is provided for closing this hole. Obviously other means might be provided for fastening the suction-fan upon the arniature shaft. h

It is the intention that the motor should be adapted to the particular current supplying the same, as for example in a closed car the motor would probably be about a sixvoltmotorl. Motors of greater voltage, however, might be employed when the vacuum cleaner is intended'for use with the ordinary house current. In using the device, the roller 21`aifords a means for gauging the position of the machine with respect to the nozzle as illustrated in Figs. 1 and 3.

The device is simple and easily constructed and taken apart or repaired, since the base and casing are detachable, and the 'nozzle is detachable from the casing, also the suction fan may be easily-removed and re-attached. i i The idea is to make the device as light and simple as possible, So that it will occupy as little space as possible, making it easy to carry it about with the usual equipment of the car. i

7e claim:

A vacuum cleaner including a base, a

casing divided by a partition into two chambers, one a motor chamber and the other a suction chamber, tie-rods extending from the partition to the base adapted to secure the base and casing together, a motor arranged in the motor chamber, the armature of which protrudes through the partition into the suction chamber, a suction fan removably secured to the protruding end of the armature shaft, a nozzle removably secured to the suction chamber, means projecting downwardly from the base and provided with a roller` adapted to support the rear of the cleaner, and gauge the nozzle with respect to the surface being cleaned, an operating handle extending from the base, anda dust bag detachablysecured to a discharge spout on the suction chamber.

i In testimony whereof we affix our signatures.
