'7 Claims.

The present invention relates to suction cleaners in general and particularly to new and novel improvements in odorizer units in suction cleaners. More specifically the invention comprises a new and improved suction cleaner unit incorporating odor-creating means, the odor-creating means remaining operative, if desired, when the cleaner is used in combination with a dusting tool unit.

The odorizer unit in a suction cleaner performs .a valuable function by disguising the dry dust smell caused by that very small percentage of foreign matter which is not removed from the air by the filtering medium of the cleaner. Odorizer units have heretofore been incorporated into a suction cleaner construction so that they operated in the .use of the cleaner in on-the-fioor cleaning. With the cleaner converted for oilthe-floor cleaning, however, additional odor creating means were necessary as the cleaning air in entering the cleaner no longer passed over the volatile element. By the present invention a construction has been provided in which the odorizer unit remains operative in both the onthe-fioor cleaning and the oii-the-floor cleaning relationshipsof the suction cleaner.

It is an object of the present invention to provide a new and improved suction cleaner. .It is another object of the invention to provide new andimproved odor-creatingmeans in a suction cleaner. A further object is the provision in a suction cleaner of an odorizer unit thru which air is drawn by the suction-creating means of the cleaner when the cleaner is used in on-thefloor cleaning and also when it is used in off-thefloor cleaning. Still another object is the provision, ln a suction cleaner, of an odorizer unit which is" interiorly connected to the eye of the suction-creating fan and fan chamber. A still further object is the provision of a suction cleaning unit, including an-odorizer unit, which is adapted to receive and cooperate with a dusting tool unit without affecting the operation of the odorizer unit. These and other more specific objects will appear upon reading the following specification and claims and upon considering in connection therewith the attached drawing to which they relate.

Referringnow to the drawing in which preferred embodiments of the present invention are disclosed:

Figure 1 is a side elevation of a-modern suction cleaner incorporating the present invention;

Figure 2 is a partial bottom view of the cleaner 1935, SerialNo. 11,935

shown in Figure 1 illustrating the odorizer unit; Y

Figure 3 is a partial bottom view of the cleaner shown in Figure 1 with the dusting tool converter. connected for ofi-the-floor use;

Figure 4 is a section through the cleaner upon the line 4-4 of Figure 2 with the machine related for on-the-fioor use;

. Figure 5 is a section upon the line 5-5 of Figtire 3 in which the machine is related for off-thefloor use; I

, Figure 6 isa section upon the line 6-6 of Figure 3 showing the air passageway connecting the odorizer unitto the eye of the fan chamber;

Figure 7 is a section similar to Figure thru 5 a modification in which the interior of the odorizer unit is connected into the eye of the fan chamber at a slightlydifferent position;

Figure 8 is a view in perspective of a cake of volatile element adapted to be .used in the present invention.

In the drawing a modern suction cleaner ,is disclosed. The cleaner nozzle i is interiorly connected through an air passageway 2, having a removable section 3, to the eye 6 of the fan chamber 5. Within the fan chamber 5 is a rotatable fan 6 which is carried upon the lower end of a motor shaft 1 and which functions, in the operation of thecleaner, to create a reduced pressure at the eye of the fan chamber which is also effective in the air passageway 2 and nozzle 5. This reduction of-pressure causes a flow of air from the nozzle, thru'the air passageway 2 and into fan chamber 5. From that chamber the air the position of I is exhausted, underthe force of the fan 6, through o the exhaust outlet 8 into the removable dust bag 9 removably secured thereto by suitable means Ill. The motor casing H is positioned immediately above the fan chamber 5 and the motor proper, while not shown, is any common and well- 40 known type adapted for suction cleaner usage., The cleaner body is movably supported by front and rear wheels l2 and 13, the latter preferably being provided with adjusting means M by which they may be adjusted relative to the body of the machine for thepurpose of'raising and lowering the nozzle l. A handle I5 is pivoted at the sides of the fan chamber 5 and is provided with an arcuate sector I 6, the outer surface of which is provided with suitable seats I! which arev adapted to cooperate .with a spring-pressed detent l8 to position the handle.

With the cleaner in its on-the-fioor cleaning relationshipjthe nozzle l is connected directly to the fan chamber 5 through the air passageof air through said odorizer housing and into said fan chamber.

4. In a suction cleaner, suction-creating means adapted to be connected to a floor nozzle or to a dusting tool unit, a volatile element container connected directly to said suction-creating means so as to be unaffected by the connection of said means to a floor nozzle or to a dusting tool unit, and means controlling the flow of volatilizing air thru said container.

5. In a suction cleaner, suction-creating means adapted to be connected to a floor nozzle or to a dusting tool unit, a volatile element container connected directly to said suction-creating means so as to be unafiected by the connection of said means to a floor nozzle or to a dusting tool unit,

'means connecting said container to atmosphere,

and manually operable means controlling the flow of air into saidcontainer.

6. In a suction cleaner, suction-creating means adapted to be connected directly to a floor nozzle or directly to a dusting tool unit, a volatile element container connected directly to said suc- '7. In a suction cleaner, suction-creating means adapted to be connected directly to a floor nozzle or directly to a dusting tool unit, a volatile elementcontainer connected directly to said suction creating means so as to be unafiected by the connection of said means to a floor nozzle or to a dusting tool unit, means connecting said container to atmosphere, a manually operable valve including a handle adapted to control the flow of air thru said container, said handle being extended adjacent a stationary part of the body of said cleaner, and position indicating means on said stationary part cooperating with said handle to indicate the position of said valve.
