Definitions

  • This invention relates to suction cleaners and more particularly to improvements in nozzle height positioning means in a suction cleaner.
  • Suction cleaners are usually provided with a nozzle height adjusting device which is manually adjusted.
  • a disadvantage of this type of manual nozzle adjustment is that the operator unknowingly mis-sets the device by adjusting the nozzle to a higher position than required and thereafter continues to use the cleaner with the nozzle improperly adjusted.
  • a normal nozzle height position is provided for optimum cleaning efiiciency for a relatively wide range of rugs, and a manual device is provided for moving the nozzle to a higher adjusted position for extremely thick rugs.
  • the manual device is rendered inoperative when the cleaner handle is moved to a rest or storage position and the nozzle is automatically preset to return to its normal position upon movement of the handle into its operating range. Thus the operator can not continue to use the cleaner with the nozzle adjusted to a higher position than is required.
  • Figure 1 is a bottom view of the cleaner with parts broken away;
  • Figure 2 is a view taken along the line 22 of Figure 1 and showing the nozzle in its normal position;
  • Figure 3 is a view similar to Figure 2 but showing the nozzle adjusting means in its high position to adjust the nozzle for extremely thick rugs, and also shows in dotted lines the handle in a rest position to raise the nozzle a greater distance from the rug; and
  • Figure 4 is a perspective view of the nozzle adjusting device.
  • the embodiment of the invention herein disclosed comprises a cleaner body provided with a nozzle H), from which extends an air passageway II and a belt conduit l2 each terminating in a trunnion l3 on which is rotatably mounted a motor fan unit l4- having a fan chamber !5 provided with an inlet 56.
  • a suction creating fan I! driven by an unshown motor having its shaft provided at its opposite end with a belt pulley l8 projecting into the belt conduit It.
  • a belt !9 extends from the pulley i3 through the conduit E2 to a surface agitator 2t rotatably mounted in the nozzle ill.
  • An opening 25 is provided in the suction air passageway H opposite the fan chamber inlet It for reception of an unshown converter when it is desired to employ the cleaner for offthe-iloor cleaning.
  • a cover 22 normally closes the port 25.
  • Extending from the fan chamber i5 is an outlet 23 to which the lower end of a dirt filtering bag 2 is connected and the latter is attached at its upper end to a handle 25 supported on the housing of the motor fan unit I4.
  • the combined handle 25 and motor fan unit it are yieldably held in the low position shown in Figure 2 and in rest position shown in dotted lines in Figure 3 by a spring-pressed lever 2! rotatably mounted on the stationary portion of the cleaner body and provided with a roller 28 which rides upon an arcuate sector 29 formed on the motor-fan housing, and the sector 29 is provided with seats 38 and 3!.
  • a spring-pressed lever 2! rotatably mounted on the stationary portion of the cleaner body and provided with a roller 28 which rides upon an arcuate sector 29 formed on the motor-fan housing, and the sector 29 is provided with seats 38 and 3!.
  • the cleaner body is supported on front wheels 33-33 and rear wheels 3434 the latter being mounted on brackets 35 extending from the cleaner body.
  • the treads of the front wheels 33 ar relatively broad in comparison to the rear wheels 34 and this combination of wheel treads provides automatic adjustment of the nozzle III for a wide range of rugs.
  • the front wheels 33 are rotatably mounted on the offset ends 36 and 3'! of a shaft 38 having other offset portions 3939 which are rotatably attached to the cleaner body by brackets if] and M.
  • a foot operated nozzle adjusting device comprising a lever 45 pivotally mounted on a pin 46 supported by a lug 4'! and the side Wall 48 of the cleaner body, and the lever projects through a slot 49 in the body and is provided at its outer end with a pad 55 to receive the operators foot.
  • a torsion spring 5 normally urges the lever 45 clockwise, as viewed in Figure 2, against the upper stop limit 52 of the slot 49.
  • An elongated slot 53 is provided at the inner end of the lever 45 and rotatably receives a pin 54 mounted at one end on a sector 55 pivotally supported on a pin 5'6 attached to the body side wall 43.
  • Two seats 5'! and 58 are formed in the sector 55 for engagement with the offset portion 3-! of the wheel shaft 33, and when the latter is in the seat 5? the nozzle is adjusted in its normal position relative to the rug indicated at 55, as shown in Figure 2, and when the seat 58 receives the shaft end 31 the wheels 3333 are moved downwardly to raise the nozzl to its adjusted position relative to the rug BI, shown in Figure 3, for cleaning extremely thick rugs.
  • a member 65 is rigidly attached to the offset portion 39 of the wheel shaft 38 and extends into the path of a pin 68 mounted on the housing of the rotatable motor fan unit 44.
  • the pin 86 engages the member 65 to rotate the wheel shaft counterclockwise and lower the front wheels 33 to thereby raise the nozzle i0 and agitator 2D to an inoperative position with reference to the rug indicated at 61.
  • the manual nozzle adjusting device In the operation of the cleaner on all but extremely thick rugs the manual nozzle adjusting device is in its normal position shown in Figure 2 with the lever 45 urged by the spring 5! against the top 52 of the slot 49 and the sector seat 5'! resting against the offset portion 3'! of the wheel shaft, to thereby maintain the front wheels 33 and the nozzle is in their normal positions.
  • the shaft spring 44 exerts a force on the lowest offset portion 43 of the wheel shaft 58 to rotate the latter clockwise as viewed in Figure 2 to urge the wheel shaft offset 3'! into the sector seat 51.
  • the broad and narrow wheels 33 and 34 respectively maintain the nozzle ill at an optimum nozzle height for rugs of different pile depth except for extremely thick rugs.
  • the sector seat 51 maintains the front wheels 33 in their normal nozzle position during movement of the handle 25 throughout its normal operating range while moving the nozzle ll! over the rug being cleaned. If the handle 25 is moved to its storage position the pin 66 on the motor fan unit housing engages the member 65 causing the wheel shaft 38 to rotate counterclockwise, as viewed in Figure 2, about its pivotal axis 35 and disengages the wheel shaft offset 37 from the sector seat 5'! to lower the front wheel 33 and raise the nozzle It and also the agitator 29 out of operating engagement with the rug. In this inoperative position of the nozzle 1 0 the cover plate 22 can be removed and a converter inserted through the port 2
  • the operator places his foot on the pad 55 depressing the lever 45 against the force of the spring 5
  • the spring 5i urges the sector seat 58 against the shaft offset 31 to retain the latter in adjusted position, and the shaft spring 44 exerts a force against the lowest wheel shaft offset 43 to assist in seating the shaft offset 31 in the sector seat 58.
