This invention relates to nozzles for vacuum cleaners which are useable with or without bristles. The advantage of such a nozzle is that it can be advantageously used oncarpets or on floors. It is previously known to have separate brush attachments for vacuum cleaner nozzles. The disadvantage of such an arrangement is that the user must remove the brush attachment in order to use the nozzle for rugs or the like. Furthermore, the attachment is likely to be lost.
The present invention provides a brush at- 'tachment which is incorporated in the nozzles and is preferably of such construction that the bristles are movable above or below the mouth of the nozzle body. In some forms of my invention I provide independent movement of brushes on either side of the nozzle mouth which is advantageous in some forms of cleaning since some of the bristles may be positioned below the mouth of the nozzle body and others above and out of cleaning position. I
The invention will be explained by reference to the accompanying drawings, forming a part of this specification, and of which: Fig. 1 is a front elevational view of a vacuum cleaner nozzle embodying the invention;
Fig. 2 is a plan view of one end of the nozzle; Fig. 3 is a plan view of the other end of the nozzle; Fig. 4 is an end view of the nozzle;
Fig. 5 is' a vertical sectional view taken on the line VV of Fig. 1;
Fig. 6 is a horizontal cross-sectional view of Fig. 8 is a sectional view taken on the line VIII-NIH of Fig. 7;
Fig. 9 is a sectional view on an enlarged scale; Fig. 10 is a sectional view of one end of the nozzle;
Fig. 11 shows a modified form of construction embodying the invention;
Fig. 12 is a front elevational view of still another embodiment of the invention;
Fig. 13 is a plan view partly in cross-section of the structure shown in Fig. 12; 4
Fig. 14 is a vertical sectional view taken on the line XIV- m of Fig. 12; Fig. 15 is a horizontal view on an enlarged scale of the structure shown in Figs. 12 and 13; and
Fig. 16 is a detail view. Referring more particularly to the structure shownin Figs. 1 to 10, the nozzle comprises a nozzle body In having a tubular portion adapted to be connected to the suction conduit of a vacuum cleaner. The nozzle body In has an elongated mouth at the lower part thereof. At the left-hand of the nozzle body are ears |2 which are preferably castv integral with the nozzle body. 5 The nozzle body may be made of aluminum or a like rigid material. At the opposite end (the right as shown in Fig. I) are ears l3. These ears have bores and constitutes bearings for rods l6 and I1 extending to either side and longitudi- 10 nally of the mouth of the nozzle. Each of the rods l6 and I1 carries a row of bristles l4 and I5 respectively. The ends, of rods I6 and II are formed by bushings I8 and I9 which are rotatablyjournalled in the ears i2 and I3, respec- 15 tively. In order to prevent axial movement of the brush carriers in the bearings, rings "are provided which set onto the bushings l8 .and I9 and bear against the side surfaces of the ears l2 and I2. Cup-shaped members 2| fit within mem- 20 bers l8. These members extend around the outside end surfaces of member l2 and over the outside edge thereof and are rifled at 22 to form handgrips. Each of the members 2| is provided with a bottom part 23 against which a pressure 25 spring 24 bears. The other ends of these springs pre'ss against cross-pins 25. fastened 'inbushings. l8. In order to permit axial movement of the members 2| they are provided with slits 26 corresponding to the pins 25. The outer ends of the 30 cars l2 are provided with bosses or projections 21 which are adapted to enter corresponding apertures or holes 28 in members 2|. The outer openings of the ears ii are covered by disks 29 in order to prevent entry of dust into the bear- 35 ings.
As shown in Figs. 1 and 4 the bristles l and I5 project below the nozzle body and the nozzle-is in effect a brush nozzle. In order to convert the nozzle into a rug nozzle it is merely necessary 40 only to pull the members 22 outwardly, turn the brush carries and let go of the members.
22. On pulling members 22 outwardly the projecleft up as shown in Fig. 5 with the rear brush member down so that the nozzle mouth 45 is 5'5 above the floor and the rear brush carries along dust or litter to be sucked into the nozzle.
A somewhat different form of construction is shown in Fig. 11. Ears I2 and I3, like the previous embodiment, are fixed with respect to the nozzle body. Members I8 and I9 are turnably mounted in ears I2 and I3 and are longitudinally movable therein. The brush rods I6 and H are attached to members I8 and I 9 as by screws. The
In order to turn the bristles in this embodiment into or out of cleaning position member I9 is pulled against the action of spring 34 whereby screw 30 is disengaged from the recess 3i and can be turned 180 so as to enter and lock in recess 3Ia.
The arrangement shown in Figs. 12 to 16 differs from the above described forms more particularly in that the bristles l4 and I5 are moved simultaneously. Rods 31 pass through bearing mem bers l8 and I9 and the brush carriers I6 and H. The rods 31 are rigidly connected to oval- shaped caps 38 and 39 by means of nuts 40 and 4| Rods 31 are provided with helical grooves 42 which extend a one-half turn with respect to the circumference thereof. The grooves are cut in opposite sense with a left-hand on the one and right-hand onthe other. These helical grooves cooperate with projections 44 (Fig. 16) which are screwed firmly into the bearing members I8 and I9. Both rods 31 are longer than the distance between the rod ends of the members I8 and I9 by the distance a. This distance is equivalent to the circumferential extent of the helical grooves.
By moving the cross pieces 38 and 39 to the right (in the figures) and thereby the rods 31 by the length a, the members I8 and I9 and consequently the brush carriers and the brushes II and I5 will be turned The brushes are locked in their extreme positions by straightening out the ends of the helical grooves longitudinally of the rods 31. Movement in the opposite direction returns the brushes to their original position.
It will be obvious to those skilled in the art that various alterations in the structure may be made within the scope of the invention.
What I claim is:
A nozzle for vacuum cleaners including a nozzle body having an elongated mouth, a hollow tube turnably mounted on each side of said mouth, brush bristles secured to said tubes, rods formed with helical grooves passing through said tubes,
projecting members on said' tubes engaging said
