4 Claims. (Cl. 15-373) My invention relates to cleaning tools for use in connection with vacuum cleaners and more particularly to a cleaning tool which is capable of cleaning two difierent types of surfaces.

Heretofore, cleaning tools of this nature have been formed with difierent types of nozzles on opposite sides and have been pivotally mounted on a cylindrical suction conduit so that they could be turned over in order to bring either of the nozzles into operative position with respect to the floor or other surface being cleaned. However, this construction limited the minimum overall height of the tool, as this dimension had to be greater than the diameter of suction conduit required for the desired air flow. A small height is advantageous in order that the tool may be manipulated underneath low furniture.

In accordance with my invention one nozzle is arranged outside the other and is vertically movable with respect thereto so that, when the outside nozzle is in its raised position the inner one is in contact with the surface to be cleaned, while lowering of the outside nozzle brings it into operative relation. This eliminates the necessity of the swivel mounting on a cylindrical conduit, making possible the use of a wide flat conduit, thus reducing the height of the tool.

Further objects and advantages of my invention will be apparent from the description considered in connection with the accompanying drawings which form part of this application and. of which;

Fig. 1 is a top view of a nozzle in accordance with my invention;

Fig. 2 is a front view of the nozzle shown in Fig. 1;

Fig. 3 is a view similar to Fig. 2, but with certain parts in difierent positions;

Fig. 4 is a bottom view of the nozzle shown in Fig. 1;

Fig. 5 is an end view of the nozzle, looking at the right end of Figs. 1 and 2;

Fig. 6 is an end view of the opposite end of the nozzle, looking at the left end of Fig. 3; and

Fig. 7 is a cross-sectional view taken on the line 7-7 of Fig. 2.

' Referring to the drawings, reference character 10 designates generally an elongated rug nozzle having spaced forward and rear lips 12 and 14, respectively, and a centrally located suction conduit connector member 16 having a channel 17 which communicates with the space between the nozzle lips. Member 16 is formed with a cylindrical surface which is engaged by similar surface formed on a suction conduit 18 which is pivotally connected at 20 to the member 16. Conduit 18 is formed with a slightly tapered bore 22 which is adapted to frictionally receive the end of a hollow wand connected by means of a suitable hose to a source of suction.

As will be seen from a comparison of Fig. 4 with Fig. 7, channel 17 has a substantially greater Width than height, thus enabling the latter to be substantially less than the diameter of cylindrical conduit 18, while maintaining the cross-sectional areas of channel 17 and conduit 18 about atent ice 2 equal. It Will be noted from Fig. 7 that the height of the nozzle from the floor to the top of member 16 is no greater than the diameter of conduit 18, and hence if the nozzle were pivotally mounted on a conduit of this diameter, it would have to have a considerably greater height.

Mounted above the rug nozzle 10 is a second nozzle comprising a brush supporting structure 24 which has a longitudinally extending space 25 and cut out portion 26 extending inwardly from the central part of its rear edge to accommodate the connector member 16. Structure 24 is slightly wider than the rug nozzle 10 and carries a forward row of brush bristles 28 extending downwardly in front of lip 12 and a rear row 30 behind lip 14. Structure 24 and the bristles 28 and 30 together comprise a brush nozzle. The rug nozzle 10 is formed at each end with portions 32 which outwardly extend beyond the ends of bristle rows 28 and 3d, as shown in Fig. 4, and upwardly into recesses 33 in the end of structure 24, as is shown in Figs. 3, Sand 6.

The structure 24- is connected to the rug nozzle at one end by means of pivoted arms 34 and 35 and at the other end by means of pivoted arms 38 and 4h. Arms 34 and 36 are pivotally connected to each other at 42, while arm 36 is pivotally connected to structure 24 at 44 and arm 34 is pivotally connected to nozzle 16 at 46. Arm 34 is pivotally and slidably connected to structure 24 by means of a pin 48 on the structure engaging a slot in the arm, while arm 36 is similarly connec'tfi'to nozzle 19 by means of a pin 50 on the nozzle engaging a slot in the arm. Arm 35 is extended at its rear end to form an operating handle 52 which may be stepped on to apply force thereto in a direction to lower the structure 24 with respect to the nozzle 10.

The arrangement at the opposite end of the nozzle is similar to that just described, with the exception that the rear end of the arm 43 is formed with an extension 54 which may be stepped on in order to apply a force in a direction causing the structure 24 to be raised with respect to the nozzle 10. The arms 34 and 38 are connected together by being connected to opposite ends of a rod 56 which extends the entire length of the nozzle 10 so that these two arms and consequently the linkages at opposite ends of the nozzle are forced to operate in unison, thus assuring that both ends of the structure 24 will be moved through equal distances with respect to the nozzle 10.

If desired, a bumper of rubber, plastic or the like 58 may extend around the structure 24 in order to prevent the tool from marring the furniture or the like with which it may he accidentally brought into contact while cleaning a rug.

With the parts in the position shown in Figs. 2, 5 and 7 it Will be noted that the bristles 28 and 30 extend downwardly below the lips 12 and 14. Consequently, the tool is in condition for cleaning a hard Wood floor or other hard surface covering, inasmuch as the bristles will contact this surface, while the nozzle lips are held above it. If suction is applied to the conduit 18 and the tool is moved over a dusty surface, the bristles 23 and 30 will dislodge the dirt which will be picked up by the air stream flowing through the bristles and will be carried between the lips 12 and 14 and into the connector member 16 and thence to the suction conduit 13.

if it is desired to convert the tool to a rug cleaner, the operator applies a downward force to the handle 54 of arm 40, this causes the arm to pivot in a counterclockwise direction, as viewed in Fig. 6 to the position shown in this figure so as to raise the bristle supporting structure 24, the pin on nozzle 10 sliding to the opposite end of the slot in arm 40. At the same time arm 38 is pivoted in a clockwise direction, as viewed in Fig. 6, as

the structure 24 is raised and this motion'is transmitted through the rod 56 to the arm 34 at the other end of the nozzle, causing it to pivot in a counter-clockwise direction, as viewed in Fig. 5, so as to raise this end of the structure 24 and thus both ends of the structuretare raised: simultaneously. As is shown in Figs. 3 and 6, when the structure 24 is raised with respect to'the nozzle 19,- the'lower'e'nds of the bristles 28 and 30 are retracted to a position above the nozzle lips 12 and 14 and consequently the latterwill contact the surface to be cleaned. Application of suction as above described, will cause the air and entrained dirt to be drawn into the nozzle in the usual manner. e 1

When it is desired to againbring the bristlesinto'operative positionthe operator applies a downwardly directed force to the end 52 of the arm 34 so as; to cause this arm to pivot in a clockwise direction, as viewed in Fig. '5. This lowers the structure 24, the pin 48 sliding in the slot in'the arm 34. At the same time, therod 56 transmits this motion to the arm 38 at the other end of the device, which causes it to pivot in a counter-clockwise direction as viewed in Fig; 6, thus lowering this end of the structure 24. V v p V The structure 24 is retained in whichever position it isplaced by friction. Thus, the pivots 42 between the arfns may be in the form of screws which may be tightened 'so as to adjust this frictional resistance to movement.

It will thus be seen that I have provided a suction tool of minimum height which may be readily converted from one type of cleaning nozzle to another. Regardless of which type of nozzle is in operative position, the suction conduitifi may be pivoted with respect to the rest of the tool in any manner without interfering with or atr'ecting the flow of air. Such pivoting is desirable in order that the tool may be moved under low furniture so that the floor or rug thereunder may be cleaned} without necessitating moving the furniture. ,1 a
