Definitions

  • his invention relates to suctioncleaners and more particularly to one which may be readily converted to oii-the-iloor cleaning operations bythe insertion of a converter tube, attached ⁇ to a cleaning tool by means of a flexible hose, into a converter passageway leading to the suction eye of the fan.
  • a converter passage is provided beneath the exhaust passage and extends rearwardly from the fan eye between the rear supporting wheels ofthe cleaner.
  • the converter passageway is positioned above the belt and pulley which drive the agitator from the fan shaft andthe converter tube is so formed as to straddle the pulley shaft above the pulley and belt lengthwise of the beltjfrom the pulley end thereof.
  • the converter passageway is normally closed oit from the fan eye by a converter valve positiene@ immediately to the rear of the fan eye and is normally obstructed by a portion ofthe shaft which carries the rear wheels.
  • the converter is so made that its insertion into Vthe converter passageway will both raise thenrear wheels and open the converter valve.
  • the rear of the cleaner may be depressed to raise the wheels and remove the barrier from the converter passageway whereby the converter may be freely inserted.
  • the rear wheels ⁇ are normally spring-biased downwardly and after the converter tube is inserted the barrier locks the converter in place whereby the cleaner may be propelled rearwardly by pulling on the dusting tool hose.
  • the converter tube is also formed with a slot for receiving the pulley shaft and with a sort of clam shell valve arrangement which engages with the pulley shaft as the converter is inserted to automatically move the two parts apart and when the converter is completely inserted the two parts close about the pulley shaft to completely seal the fan eye from the suction passageway and estabish suction communication between the fan eye and the dusting tool hose.

  • the reerenceenumeral I0 represents the body of a suction cleaner of conventional form except for the manner in which the converter passageway is positioned relative to the fanA eye.
  • the body Ill is mounted for ambulatory movement by front wheels II and rear wheels I2.
  • a propelling handle I3 is shown in Fig. 1 in the midposition of rest atabout 45'to the horizontal.
  • a motor driven fan (not shown) draws dirt-laden air into the nozzle I4, through a suction passageway I5; ⁇ into a :fan eye IG and discharges it through an exhaust passageway I'I into a lter bag I8.
  • 91of-usualconstruction is rotatably mounted in the nozzle
  • a bottom plate 23 closes oif the bottom side of the suction passageway I5 and is removable to provide easy access to the belt 20.
  • a converter passageway 24 lextends rearwardly from the fan eye I6 below the exhaust passageway Il and 4between the rear wheels I2.
  • the converter passageway ⁇ 24 is normally closed by a valve 25 which is spring-biased to closed position by aspring 2G.
  • 2 ⁇ are rotatably mounted on spindles 21 formed on the ends. of a frame or shaft 28 pivotally secured to the bottom of the body I0 by clamping brackets"29- ⁇
  • the spindles 21 are offset from the pivotal axis of the shaft 28 by crank arms 30.
  • Centrally of the shaft 28 is a U-shaped crankV arm 3
  • the bottom wall of the converter passageway 24 iscut away at 32 to provide for the passage of crank arm 3
  • the converter element ⁇ is somewhat tlike ⁇ that shown in Figs. ⁇ 5.110 ⁇ 8.1 inclusiva olf thepatent to White 2,450,846 and comprises a converter tube for attachment to one end of a dusting tool hose and shaped for insertion into the converter passageway 24. Near its forward end the top wall of the tube 4i! is out away at 4
  • the bottom wall of the tube 4S is bent upward slightly at 43 (Fig. 1) and slotted at 44.
  • an end piece 46 slotted at 41 and having upwardly inclined ends 43 for engagement with the crank arm 3
  • the end piece 46 is spaced from the bottom wall of the tube 4
  • the valve elements 49 and 5G are biased against each other by spring 5
  • the valve elements 45 and 5i! are provided with upturned ends 53 and 54 bent rearwardly as shown at 55.
  • the bottom wall of the tube 40 is indented at 56 to cooperate with the crank arm 3
  • the converter tube 45 may be inserted into the converter opening 24 in either of two ways. Pressure may be applied to the rear of the body Ill by means of the handle I3 or otherwise to remove the crank arm 3
  • the shaft 28 will be pivoted counterclockwise so as to raise the rear wheels I2 relative to the body Iii and permit the body to pivot about the front wheels II and raise the nozzle I4 to such an extent that the surface covering will not be drawn upwardly against the nozzle. It is to be noted that in either case the converter tube 443 cannot be inserted until the nozzle is raised.
  • will snap into the recess 56 under the bias of springs 33 and lock the converter tube 4E in place whereby the cleaner may be pulled about by pulling on the dusting tool hose.
  • a sharp pull may be applied thereto to remove the crank arm 3
  • shaft 22 will engage the arcuate recesses in the valve elements 49 and 5D and bias them outwardly during the removal of the converter tube 40.
  • the positioning of the converter opening between the rear wheels beneath the exhaust passageway has a number of advantages. In propelling the cleaner by pulling on a dusting tool hose the pull is applied at a low point on the cleaner whereby the cleaner is not liable to be tipped over. Additionally, the converter occupies a space not ordinarily utilized and the converter opening is normally out of sight so that no closure is necessary. Furthermore, the converter passageway by being located between the rear wheels is in a convenient location for utilizing the converter for raising the rear wheels and thus raising the nozzle for conversion cleaning and also for utilizing the converter when in inserted position for locking the rear wheels in their normal raising position. The converter is also located in a convenient position for utilizing the rear wheel nozzle adjustment for locking the converter in place whereby the cleaner may be moved about by merely pulling on the dusting tool hose.
