- J4. ATTORNEY Patented Nov. 17, 1942 VACUUM CLEANER Josef Friedrich Heuberger, Stockholm, Sweden,
assignor to Electrolux Corporation, Dover, Del., a corporation of Delaware Application October 30, 1933,
In Germany December Claims.
My invention relates to vacuum cleaners and more particularly to apparatus for conditioning air passing through a vacuum cleaner.
My invention will be understood by considera tion of the following description taken in conjunction with the accompanying drawing forming a part of this specification and of which:
Fig. l is a view essentially in cross-section showing a vacuum cleaner embodying the invention;
Fig. 2 is a cross-sectional view of a part of the structure shown in Fig. l; and
Fig. 3 is a cross-sectional view taken on the line 3-3 of Fig. 2. r
The vacuum cleaner includes a casing Ill. The casing l0 includes a central barrel portion 9 and end caps H and I2. End cap H is provided with a suction opening in which is fitted a coupling member 3| adapted for connection to a hose for drawing dust-laden air to the cleaner unit. The end cap II is held in place by spring clips 11. A dust bag 32 is positioned within the casing and is also held in place by spring clips IT, a flange at the open end of the dust bag being held between end cap II and the barrel portion 9. Behind the dust bag is a fan 33 driven by a motor 34 which produces flow of air in a direction of the arrows. Behind the motor in the end cap I2 is a filter Hi. This filter may consist of a plurality of layers of cloth mounted on a frame and frictionally held within the casing and extending across the Whole casing so that all the air passing through the casing is forced to pass through the filter.
The end cap I2 is provided with an outlet 2..
port l3 within which is positioned a plurality of inclined vanes I4. The end cap i2 is also held in place by spring clips 11.
The present invention resides essentially in the receptacle l8 and its operation. This receptacle is situated within the space 35 between the filter l6 and theoutlet port I3 but it is positioned to one side of the direct path of flow of air through the outlet port 13. The receptacleis shown in detail in Figs. 2 and 3. It is made up of two telescoping cylindrical parts l9 and 20. The outer part I9 is securely fixed in an opening 36 in the casing. It will be seen that this opening 36 is to one side of the outlet port 13. side of the casing so as to be readily accessible. Part I9 is closed at the bottom and provided with lateral longitudinal slots 2|. The 'inner member 20 is closed at the top in the form of a cover It is preferably on the top Serial No. 695,863
23 accessible from outside the casing and is formed with longitudinal slots 22. These slots 2| and 22 are so disposed that by turning the cover 23 the receptacle l8 may be closed or open. When the slots 2| and 22 are aligned the air flowing within the casing has access to the interior of the receptacle and air conditioning material contained therein.
The receptacle as a whole completely closes the opening 36 in the casing so that air cannot leak out atthis point. The inner member 20 is removable to provide access to the receptacle through the opening 36 for placing air conditioning material therein. This may be conveniently done as shown by using a solid air conditioning material, which may be a perfume or a disinfectant in the form of a cylinder having a central passage 21. The cylinder of vaporizable material 26 is held on a spring member 25 which is bent to a circular form at the top to set into an inner groove in the cover 23. The edge of the cover is preferably knurled to provide a hand grip for rotating the cover to close and open the receptacle. Preferably the top of the cover is marked with a pointer or otherwise to show when the receptacle is closed and open.
The operation of the apparatus is as follows: Assume that a room is to be charged with a given perfume, deodorant substance or other air conditioning substance. A stick of the vaporizable substance is placed on the spring 25 and the inner member 20 and cover 23 is then set into the outer member 19 of the receptacle. The cover is then moved to show that the slots 2i and 22 are in alignment so that air within the casing has access to the interior of the receptacle. The motor is then started by the usual switch and air passes through the casing.
It will be appreciated that it is relatively easy with this arrangement to utilize different air conditioning materials, for example to use one kind of perfume in one room and another kind in another. This involves merely the changing of the perfume stick 26. The air conditioning member is placed to one side of the outlet 13 so that it will not produce a resistance to air flow through the outlet port I3. In the past it has been'customary to place air conditioning material in the outlet port IS with consequent increase in resistance to flow.
The receptacle I8 is placed between the filter I6 and the outlet 13 so that the perfume or other air conditioner will not impregnate the filter l6 and have the filter give off the air conditioning material after the receptacle has been closed or a different air conditioning material substituted.
If it is desired not to use the air conditioner it' is merely necessary to turn the cover 23'to close the receptacle.
It will of course be obvious that variations may be made and the invention is not limited to a stick of air conditioning material as shown.
What I claim is:
1. A vacuum cleaner comprising a casing having an outlet port and an opening to one side of said outlet port, and a receptacle for air conditioning material extending within said casing and closing said opening, said receptacle including telescoping perforated parts for closing and opening the receptacle with respect to flow of air within the casing while preventing flow of air through said opening,
2. A vacuum cleaner comprising a casing having an outlet port and an opening to one side of said outlet port, and a receptacle for air conditioning material extending within said casing and closing said opening, said receptacle including telescoping perforated parts for closing and opening the receptacle with respect to flow of air within the casing while preventing flow of air through said opening, one of said parts having a spring-like support thereon for holding air conditioning material.
3. A vacuum cleaner including a casing having an outlet port and an opening adjacent to said port and a receptacle for air conditioning material extending within said casing, said receptacle including telescoping parts having openings therethrough for the access of air thereinto, the outer of said parts being secured in air-tight manner within said opening, the inner of said parts forming a closure for the outer end of said outer part and extending outside said casing so as to be removable, and means for supporting air conditioning material within said inner part.
4. A vacuum cleaner including a casing having an outlet port and an opening adjacent to said port and a receptacle for air conditioning material extending within said casing, said receptacle including telescoping parts having alignable apertures therethrough, the outer of said parts being secured in air-tight manner within said opening, the inner of said parts being reciprocably and rotatably mounted in the outer part and forming a closure for the outer end of said outer part, the outer end of the inner part being formed as a hand grip extending outside said casing whereby said inner part may be rotated to bring said apertures into and out of alignment and may be withdrawn from the outer part, and means for securing air conditioning material within said inner part.
5. A receptacle for air conditioning material including telescoping parts having alignable perforations therethrough, said parts being relatively movable rotationally and reciprocably, one end of said outer member being closed and the opposite end of said inner member being closed and forming a closure for said outer member, the closed end of said inner member being expanded beyond said outer member to form an inner annular groove and a hand grip portion whereby said inner part may be rotated to bring said apertures into and out of alignment and may be withdrawn from the outer part, and a member having a resilient portion engageable within said groove, said member being adapted to hold a solid vaporizable air conditioning substance.
