6 Claims.
suction cleaner embodying twonozzles, only one of which contains driven surface-agitating means, which are separated by an airftunnel yet are in close proximity so that the agitation produced by the agitating means in the one nozzle is effective to disturb embedded foreign matter in that part of the surface covering contacted by the second nozzle; i It is an object of the present invention to provide a new and improved suction cleaner. It is a further object to provide, in a suction cleaner, a new and novel combination of nozzles and agitating means. A still further objectis the provision, in a suction cleaner, of an agitator-com,
In the drawings,.in which the preferred em-. I
' easily move the cleaner over the surface covering bodiment of the present invention is disclosed? Figure 1 discloses a suction cleaner embodying the present invention in side elevation, a cross section being shown through the two nozzles and fan chambers;
Figure 2 is a rear view of the cleaner shown in Figurel;
Figure 3 is a bottom view of the cleaner shown in Figures 1 and 2. l T
In the drawings illustrating the present inven-. tion a low suction agitator-containing nozzle 1 is shown interiorly connected to the-fan chamber 2; within which is positioned a suctioncreating fan 3. The nozzle 11 is provide'd with front and rear surface-contacting lips 4 and 5,
respectively. In the rear of nozzle 1' is positioned the highsuction nozzle 6, which includes ex-; tremely thin, surface-contacting lips 8, 8 of a 10 which extends forwardly fromthemotor 11 (c1. 'IS-s) thru the two fan chambers and into the forward nozzle 1 where it is provided with a pulley 12.
Within the low suction nozzle 1 is positioned a rotatable agitator 14 of a common and wellknown type which includes rigid beating elements 15, 15 and a brushv 16.- Between its ends the agitator 14 is formed as a pulley surfaceand between this surface and the pulley 12, carried by motor shaft 10, is positioned a belt 1'7, which functions to drive .the agitator upon the rotation of the shaft.
The fan chambers 2 and 7 are provided with adjacent exhaust outlets 18 and 19, respectively, which open into bags 20 and 21 of air-pervious material which permits the air topass therethrough while retaining the foreign matter carried thereby. A
As-in the usual suction cleaners, front supporting wheels 22, 22 are provided .which are carried by a supporting shaft 23, there being means, indicated generally by the reference character 24, by which the wheels canbe adjusted vertically relative to the cleaner for the purpose of raising and lowering the nozzles 1 and 6 with respect to the covering undergoing cleaning;
Rear supporting wheels 25, 25'are attached to I the motor 11 and together with the front supporting wheels, make it possible for the operatorto undergoing cleaning, there being a pivoted handle 26 provided through which the moving force can be exerted.
In the suction cleaner constructed in accordance with the present invention the nozzles 1 and 6 are spaced as is clearly indicated in Figures 1 and 3. The space between the rear lip 5 of the nozzle 1 and the front lip 8 of the nozzle 6 is of such dimensions that an air tunnel is formed between the two nozzles of such size that suflicient,
air "can pass therethru to supply the svfctioneh fective along the entire length of lips 5 and 8, As is clearly seen in Figure 3, this tunnel, which is indicated by the reference character 27, is teriorly connected to atmosphere through open ings 28, 28.
In the operation of the suction cleaner constructed in accordance with the present invention, upon the rotation of the motor shaft 10 a negative pressure or suction is created within the nozzles 1 and 6 by the rotating fans 3 and 9, which draw airfrom the nozzles-into fan chambe'rs 2 and '7, and exhaust it into the bags 20 and 21; In response to the suction within the two nozzles the surface covering thereunder is lifted upwardly and into contact with the nozzle lips. Within the nozzle 1 the agitator 14, rotated by its driving belt 1'7, positively agitates, brushes, and vibrates the suspended surface covering, not only between the nozzle lips 4 and 5, but effectively between the front lip'4 and rear lip 8, so that that part of the covering between the lips 8 and 8 is disturbed. The suction within the nozzle 1 is preferably lower than that within the nozzle 6. To this end fan 3 is of smaller diameter than 'fan 9. Fan 3 handles the greater volume of air,
however,and is therefore wider than fan 9. A relatively low suction is desired within the nozzle 1 for with a greater suction, such as that desired 'within the nozzle 6, the surface covering would be lifted against the. agitator body with undue force, resulting in an excessive load upon the driving motor. In the nozzle 6, however, no restrictions as to suction need be made and the suction of that nozzle is considerably higher (than the suctionwithin the nozzle 1, and this fact, coupled with the covering vibration resulting from the agitator within the nozzle 1, results in effective cleaning by the nozzle 6. The positioning of the air tunnel 27 between the two nozzles makes possible the entrance of cleaning air under the entire length of rips 5 and 8, thereby resulting in greater cleaning effectiveness. If the air tunnel were omitted the high suction in the nozzle 6 would function to draw dirt-laden air under the common lip from the nozzle 1, a clearly undesirable relationship.
