Claims. (01.183-44) My invention relates to vacuum cleaners; more particularly my invention relates to a vacuum cleaner casing and to a vacuum cleaner filter carrier employed in conjunction with and removable from said casing.

A primary object of my invention is to provide a vacuum cleaner from which the collected dust and dirt can be easily and quickly removed.

Another primary object of my invention is to.

provide a vacuum cleaner from which the collected dust and dirt can be removed indoors without scattering the collected dust and dirt.

Another primary object of my invention is to provide a vacuum cleaner from which the filter carrier unit can be easily and quickly removed thus providing a vacuum cleaner of great compactness without need for large storage space for accumulated cleanings.

I attain these objects by my invention, an embodiment of which is illustrated in the accompanying drawings in which- Figure 1 illustrates a perspective view of an embodiment of my invention showing the filter carrier in operative position in the vacuum cleaner casing.

Fig. 2 is an exploded perspective view of my invention showing the filter carrier removed from the vacuum cleaner casing.

Fig. 3 is a view in side elevation of my invention showing the filter carrier in operative position in the vacuum cleaner casing.

Fig. 4 is a view in side elevation of my invention partially in cross-section and. with parts broken away for purposes of illustration.

Referring now to Fig. 1, the illustrated vacuum cleaner embodying my invention comprises a tubular cylindrical casing in providing an opening H which opening II is bordered by walls I2 and I3 which walls l2- and I3 are parallel to each other and extend at right angles to the longitudinal axis of the casing Ill. The opening I I is also bordered by walls I and I5 which walls H and [5 are parallel to each other and parallel to the longitudinal axis of the casing l0 and extend at right angles to the walls I2 and I3.

End member l6 carries air-inlet member I! and is threadedly engageable with the end portion of casing in (see Fig. 4). End member I6 is provided with knurled portion l8 to facilitate manual engagement of the end member IS with the end portion of casing Ill.

Only a short section of power cord i9 is illustrated, the remainder being broken away for purposes of illustration.

Knurled butt member 20 is threadedly engaged with the end portion of casing I0 and loop 2| is hingedly connected with the butt member 20 and is designed to be used in facilitating storage of the device by hanging as in clothes closets.

Hand strap 22 is illustrated as connected with filter carrier 23 although it could be connected with the casing Hi. In connection with filter carrier 23, however, the hand strap 22 serves not only to properly position the hand of the user on the device as well as suspend the devicefrom the back of the hand of the user thus taking the weight from the fingers, but also serves as a handle for the filter carrier 23 facilitating removal of the filter carrier 23 from the casing H] in the course of removing accumulated cleanings from the machine.

The filter carrier 23 is tubular and cylindrical having a slightly smaller outside diameter than the outside diameter of the portion of casing H) which carries the filter carrier 23. I

The carrier 23 is provided with a suitable filter element, a bag type being illustrated, it being understood, however, that other suitable filter types could as well be employed.

My invention of casing and detachable filter carrier is also adapted to provision of a low cost, disposable filter carrier made up of cardboard, plastic or other suitable material such that the cost would be low enough to permit the user to dispose of the entire unit in ridding the machine of accumulated cleanings and substitute a new disposable filter unit for the unit discarded.

The motor (not shown) is of conventional type as is the fan 24. Although my invention is illustrated in the accompanying drawings as embodied in a small, compact vacuum cleaner designed particularly for one-hand operation, it will be understood that the principle of the invention is equally applicable to so-called tank-type cleaners and that such application in this type of vacuum cleaner is accompanied by all of the advantages herein set forth.

The air-inlet member i1 is frictionally engaged with the end member 5 and can be removed to permit use of all standard accessory cleaning attachments well-known in the art.

Referring now to Fig. 4, the rim 25 of the butt endportion 26 of filter carrier 23 rests on washer 21 when in operative position in the casing Ill. The washer 21 is made of rubber or other suit able material and provides an airtight seal between the rim 25 and the casing In. The washer 2'! is lodged on the shoulder 28 which shoulder 28 is provided in the inside bore of easing l0 (see also Fig. 2). The forward end portion 29 of the filter carrier 23 in operative position is in airtight contact with the washer 30 which washer is similar to washer 21. The washer 30 is carried on the shoulder 3| of end member I6. As end member I6 is moved into threaded engagement with the end portion of easing ill, the shoulder 3| of end member l6 carrying washer 30 is moved into airtight contact with the rim 32 of the forward portion of filter carrier 23. The pressure exerted by the shoulder 3| on the rim 32 of filter carrier 23 3 slidably moves the entire filter carrier 23 in a rearward direction parallel to the longitudinal axis of the filter carrier 23 and the casing moving the other rim 25 of the filter carrier 23 into airtight contact with the washer 21 carried by shoulder 28. v

That is, when the end member [6 is screwed onto the end portion of easing It, the end portion of the end member is forced into airtight engagement with the rim 32 of the filter carrier 23 while the filter carrier itself is simultaneously slid into airtight engagement with the shoulder 23 in the inside of easing I0. I

While the shoulder 3| in the end member lBis not essential to the operation of my invention in that contact between the rim portion 32 of filter carrier 23 and the end portion of end member IS with a resilient washer interposed would result in an airtight seal between end member I6 and filter carrier 23, nevertheless the provision of a shoulder as shoulder 3| on end member I6 re sults in a positive interlocking action between the carrier 23 and the end member l6 and is a preferable refinement.

It is obvious that the shoulder 3| could be incorporated into the end portion of filter carrier 23 rather than in end member l6 and the same positive airtight interlocking action obtain. From the standpoint of manufacture, however, I believe the illustrated location of the shoulder 3|,

that is incorporated into the end portion of filter carrier 23 rather than in end member IE to be preferable. The threads 34 must be machined, cast, moulded or otherwise suitably incorporated into the end portion of end member IS; the shoulder 3| may be provided in the end portion in a combined operation.

The mode of operation of my inventionis as follows:

In order to remove the filter carrier 23 from the casing ID, the user simply grasps the knurled portion |8 of end member I6 and rotates the end member l6 thus tending to threadedly disengage the end member Hi from the casing Ill. The pressure exerted by the shoulder 3| on the rim 32 of filter carrier 23 is thereby relieved as a result of the movement of the shoulder 3| away from the rim 32. The filter carrier 23 is thus only loosely disposed in the casing l0 and can be removed by means of the handle 22.

The accumulated cleanings may then be disposed of and the filter carrier 23 replaced in the casing I. A manual tightening of the end mem-, ber It results in contact of the' shoulder 3| with the rim of the filter carrier 23 and in contact of the rim 25 of the carrier 23 with the shoulder 28.
