Inventor: WHton E. 505d Wfi Attorney VACUUM CLEANER BACKGROUND OF THE INVENTION This invention relates to a vacuum cleaner having a suction creating means, and more particularly, to a unique brush roller positioned within the suction nozzle of a vacuum cleaner for efficiently cleaning rugs which may be partially sucked into the suction nozzle.
As is well known in the electric vacuum cleaner art, brush rollers have been rotatably mounted in the nozzle or mouth of a vacuum cleaner and have been driven by a belt or pulley connected to the motor which drives the suction fan of the vacuum cleaner. While such brush rollers have taken various shapes and forms, many brush rollers have not been entirely satisfactorily since the bristles on the roller stall the brush and prevent it from being rotated by its pulley or belt when the carpet being cleaned is lifted or sucked partially into the suction nozzle.
SUMMARY OF THE INVENTION Correspondingly, it is a primary object of this invention to provide a brush roller which will efficiently clean rugs which are partially sucked into the suction nozzle of a vacuum cleaner without stalling the brush.
In accordance with one of the aspects of my invention, a vacuum cleaner having a suction creating means and a suction nozzle connected to the suction creating means is provided with a unique brush roller mounted for rotation in the suction nozzle. The roller is generally cylindrical and includes a generally flat surface disposed approximately perpendicular to a radius of the roller. The trailing edge of the flat surface intersects the generally cylindrical outer surface of the brush roller and the leading edge of the flat surface terminates in a wall extending substantially perpendicular to the flat surface. A plurality of bristles are mounted on the brush roller and they extend outwardly generally perpendicular to the flat surface of the roller. The bristles are located relatively close to the generally perpendicular wall and are arranged generally parallel to the perpendicular wall. In addition, the generally perpendicular wall extends from the flat surface to the outer cylindrical surface of the brush roller. Thus, when the brush roller is being rotated by its pulley or belt and a carpet is being partially sucked into the suction nozzle the cylindrical surface of the roller at the leading edge of the flat surface contacts the carpet thereby partially deforming its nap and since the cylindrical surface is spaced radially outwardly from portions of the brush bristles it insures that the side surfaces of most of the bristles rather than the tips of the bristles initially contact the carpet being cleaned. By this arrangement, the bristles in contact with the carpet are bent toward the trailing edge of the flat surface, and thus, the friction between the carpet and the brush bristles is low enough so that the brush roller is not stalled and prevented from being rotated by its pulley or belt.
BRIEF DESCRIPTION OF THE DRAWINGS Other objects and attendant advantages of this invention will be apparent from the following description taken in connection with the accompanying drawing in which;
FIG. I is a perspective view ofa vacuum cleaner incorporating the present invention;
FIG. 2 is a fragmentary perspective view of the brush roller of the vacuum cleaner shown in FIG. I;
FIG. 3 is a fragmentary side elevation view of the cleaner shown in FIG. I with parts broken away to show my unique brush roller in contact with a carpet partially sucked into the vacuum cleaner nozzle; and
FIG. 4 is similar to FIG. 3 but shows the bristles of the brush roller in fuller contact with the carpet being cleaned.
DESCRIPTION OF THE PREFERRED EMBODIMENT Referring now to the drawings and especially to FIG. I, there is shown a vacuum cleaner generally designated by the reference numeral I0 embodying my unique brush roller I2. The vacuum cleaner includes a base portion I4 having an electric motor and suction fan 15 positioned therein and an upwardly extending handle I6 having a conventional dust bag 18 attached thereto.
As shown more particularly in FIGS. 3 and 4, a conventional suction air inlet nozzle 20 is located within the forward portion of the base and is connected to the suction creating fan I5 located within the base portion of the vacuum cleaner.
The brush roller 12 which represents the preferred embodiment of my invention is rotatably mounted in any suitable manner in the nozzle 20 of the vacuum cleaner. As illustrated in FIGS. I, 3 and 4, it is driven by means of an endless belt or pulley 22 which is preferably connected in driven relationship to the motor shaft of the vacuum cleaner in a conventional manner.
As illustrated more particularly in FIG. 2, my improved brush roller I2 comprises a cylindrical body member and conventionally the body member is made of wood or suitable plastic material. A plurality of tufts of bristles 24 are suitably positioned on the brush roller, and in the embodiment illus trated, two rows of bristles are positioned in diametrically opposite rows of bores which may be drilled or otherwise formed in the brush roller. As illustrated, the bristles are spirally arranged and spiral in the same direction so that any tuft of bristles of one of the rows of bristles located the same distance from the end of the roller as a bristle tuft of the other row of bristles is approximately l apart from the first mentioned bristle tuft. This is a conventional arrangement to insure that one of the bristle tufts is always in a position to be in contact with the carpet.
In accordance with my invention, the bristle tufts are ositioned on flat surfaces 26 which are cut or otherwise formed in the brush roller dowel for permitting the bristles to lie at least partially within the radius of the outer cylindrical surface 30 of the brush dowel when a carpet is sucked partially into the suc tion nozzle. In the embodiment illustrated in FIGS. 3 and 4, two generally flat surfaces 26 are utilized, one surface for one of the rows of bristles and the other surface for the other row of bristles. As illustrated, the flat surfaces 26 are disposed approximately perpendicular to radii of the brush roller 12 and the trailing edges 28 ofthe flat surfaces intersect the generally cylindrical outer surfaces 30 of the brush roller. A unique outwardly extending wall 32 is positioned at the leading edge 34 of the flat surfaces 26. The wall 32 extends substantially perpendicular to the flat surfaces 26 and is positioned relatively close to the bristle tufts, it extends generally parallel to the bristle tufts and gently merges with the outer cylindrical surface 30 of the brush roller at a rounded corner 36.
In a preferred embodiment of my invention the generally perpendicular wall 32 is positioned approximately three-sixteenth inch from the base of the bristle tufts, the height of the wall is approximately one-fourth of the length of the bristles, and the distance from the base of the bristles to the trailing edges of the flats 26 is approximately equal to the length of the bristles. With these parameters the bristle tufts are readily deformed to lie close to the flat surfaces 26 and the brush is prevented from stalling when a carpet is sucked up into the suction nozzle 20.
OPERATION With this unique construction, when a carpet being cleaner is sucked partially into the suction nozzle 20 as illustrated in FIGS. 3 and 4, and the brush roller I2 is rotated in the direction of the arrows, as shown in FIG. 3, the cylindrical surface 30 of the brush roller will be moved into contact with the carpet pile thereby defonning the pile and shaping it so that the side surfaces 38 of most of the bristles will be placed in contact with the carpet. It can be appreciated that the generally perpendicular wall 32 insu.es that only the radial outer portions 38 of the bristles will be placed in contact with the carpet thereby preventing the carpet pile from contacting the radial inner portions of the bristles. Thus, the bristles are readily bent over toward the trailing edges of the flat surfaces. Moreover, with this construction the flat surfaces 26 and the generally perpendicular walls 32 provides a substantial recess for receiving the deformed bristles when a carpet is sucked rather forcefully into the suction nozzle. During such a condition, the bristle tufts will lie somewhat flat against the flat surfaces 26 with the tips of the bristles being quite close to the trailing edges of the flat surfaces. Thus, at the points where the bristles contact the carpet being cleaned the distance from such point to the center of the brush roller is not much greater than the distance from the center of the brush roller to the outer cylindrical surface 28 of the brush roller. This is important since a mechanical advantage is achieved by having the load applied through a shorter lever arm. It can be seen that the load lever arm is reduced as the bristles are moved closer to the axial center of the brush roller [2.
With this arrangement, the brush bristles do not provide an excessive amount of resistance on the carpet being cleaned, and the brush is not stalled due to the resistance of the bristles on the carpet pile. It can also be appreciated that the smooth glossy surfaces of the sides of the bristles will naturally have much less frictional resistance than the cutoff tips of the bristles. Accordingly, with this unique brush roller construction for shaping the bristles and the carpet pile, a stalling resistance between the bristle tufts and the carpet being cleaned is prevented.
