VACUUM'CLENER Filed June 12, 1944 27 k |NvEN-roR TGRNEY Patented Mar. 20, 1945 AUNITI-:o STATES PATENT orales Gustaf Einar zelicslonn., assignor to Electrolux Corporation, Old Greenwich, Conn., a corporation of Delaware y 4 claims. The object of this invention is to provide an [improved combination lrug and oor cleaning tool to be used in connection with a vacuum cleaner of the so-called tank type.

More specifically, it is an object of the invention to provide a coverior a duplex tool of the above type so that the nozzle not being used will tmerely necessary not be exposed. This is desirable not only from an esthetic point of view but also because the nozzle not in use may not be clean and contact 4between it and other surfaces would be undeslrable.

It is another object of the invention to provide a duplex tool in which the bumper is always at the top regardless oi which nozzle is in use.

According to the described-embodiment a cover is arranged so that when it is open the tool may berotatecl relative thereto to expose the desired nozzle and permit the other nozzle to be covered. When in place over a nozzle the cover also serves lil` the cup. There is provided s as a bumper, being provided with a rubber strip 1 around its outer edge.

For a detailed description` of a preferred emused,

Fig. 2 is a sectional view taken on a vertical plane along the line 2-2 of Fig. 3.

Fig. 3 is a sectional view taken on a transverse vertical plane through the center of the tool, and

Fig. 4 is a sectional view taken on the line d-d of Fig. 3.

Referring now to Fig. l of the drawing, reference character l@ generallydesignates a vacuum cleaner of the tank type comprising a body il housing.r a dust bag, a hlter pad and a motor-fan unit. To one end of the body is connected a hose l2 to the opposite end of which there is connected a hollow wand i3 made up of several sections telescoped together. A duplex tool Id einbodying the present invention is connected to the last section ot the wand.

When using the cleaner a person starts up the motor-fan unit to create a iow of air in through the nozzle opening in the tool, along the wand and hose, and through the dust baz and filter Dad to an exhaust.v The user can then push the :tool over the surface to be cleaned while holding on to the elbow it between the Wand and hose. It is desirable to have dierent types of'tools for cleaning bare iloors and rues. Considerable time and' trouble can be saved -by the use of a of the type with which my improved tool is to be y tools are combined in one. In order to change over from one nozzle opening to the other it is to turn the tool over.

Referring now to Figs. 2 and 3, the duplex tool comprises a hollow body I6 divided by inner walls I1 and I'B into upper and lower chambers. The body I6 is rotatably mounted on cup I9` which is pressed over the horizontal end of elbow tube 20. A bolt 2l passes through the rside 'of the body it into the end of the cup I8 ohold the body on l cient play to prevent the body from binding against the cup. An opening 22 in the walls of the cup and elbow tube provides communication between the elbow tube and the interior of the hollow body i6.

The top and bottom oi the body oi the tool are open forming nozzles 23 and Z. The nozzle 23 is used for cleaning rugs and may be provided along one edge with a comb 25 to aid in the removal of tenaciously adhering surface litter. A tubular member 2B.may be rotated to cover the teeth of the comb when it is not needed as during normal cleaning. operations. The nozzle 24 is used for cleaning bare oors and pavements. To

facilitate the removal of dirt it is provided facc so that the plate can rotate on the end of cup i9. A flange 32 near the bend of the elbow serves to prevent the ange 3| from slipping oi the end of cup I9. A rubber bumper 34 is secured around the edge of the cover except adjacent the hinge 29.

As shown in dotted lines in Fig, 3, the cover may be raised from the rug nozzle and then the tool or cover revolved relative to each other until the cover can be closed over the oor brush nozzle. The now exposed rug nozzle may then be used for cleaning without fear that lint and other `dirt accumulated on the i bristles oi the :door brush will mar any ofthe upholstery or walls with which the nozzle may come in contact.

it is to be noted that since the bumper is attached to the cover it is always near the top of the tool regardless of which nozzle is being used. f

This is desirable because the top edge is much more apt to come in contact with furniture or other objects when the tool is being used to clean tool oi the type herein sho in which the two, et a rut; or a door.

While a preferred embodiment of the invention has been described it is to be considered as illustrative only and it is intended to cover by Letters Patent al1 i'orms oi the invention falling within the scope oi the appended claims.

What I claim is:

1. A suction cleaning tool comprising a hollow tube, a hollow body member rotatably mounted on the tube, two nozzles formed in the top and bottom of the hollow body and alternately connected in communication with the tube depending on the position of the body with respect to the tube, a cover rotatably mounted on the tube arranged to cover either one o! the nozzles as desired.

2. A suction .cleaning tool comprising a hollow tube, a hollow'body member rotatably mounted on the tube, two nozzles formed inthe top and on the tube, two nozzles formed in thevtop and" bottom ci the hollow body and alternately conp nected in communication with the tube depending on the position of the body with respect to the tube, a cover rotatably mounted on the tube arranged to cover either one or the nozzles as desired,' and a resilient bumper secured around the `edger of the cover'.

4. A suction cleaning tool comprising a hollow tube, a hollow body rotatably mounted on the tube, two nozzles formed in the top and bottom of the hollow body and alternately connected in communication with the tube depending on the position of the body with respect to the tube, a bumper member rotatably-mounted on the tube, said bumper member including releasable means to engage the hollow body and means to protect at least the iront wall of the body against contact with other objects, said bumper member and the hollow body being relatively rotatable when the releasable means is released. said protecting means being disposed along a horizontal plane near the lips oi one o! the nozzles when said releasable means is engaged. said one of the nozzles in normal use being the nozzle that is out of com municationwlth the tube while the other nozzle is in communication with the tube and available for cleaning.
