Definitions

  • the present invention relates to suction cleaners in general and more particularly to an im- 'proved bag-cleaning mechanism in a suction cleaner; More speci'ca-lly the invention comprises a tank type cleaner in which collected foreign material can be removed from the filter by operator-operated means while in place in the machine.
  • Still another object of the invention is to provide a tank type -cleaneradapted to rest, in the lter-cleaning operation, with an open end uponv a supporting surface, and in which manually operable bag-shaking. means are providedv by 'which the operator can shake the lter to dislodge foreign material which falls upon the supporting surface.
  • a still further objectA of the invention is to provide a bag-shaking mechanism by which the operator, by the exertionvof al linearorce, shakes the lter bag to dislodge foreign material' therefrom.
  • a further object of:v the invention isto provide a tank type cleaner having a bag-shaking mechanism including a normally retracted operating pedal which moves into a projecting operating position upon placing the machine in a bag-cleaning relationship.
  • Figure 1 Ais a longitudinal vertical section through a cleaner constructed in accordance with the present invention
  • Figure 2 is a transverse vertical section upon the lineA 2 2 of' Figurey l anddiscloses. the coil vspring which is' loadedf in the bag-sliaking operation;
  • Figure 3 is a partial bottom view ofthe cleaner looking in the direction of' the arrows upon the line 3-3 of Figure l, part of the outer casing being broken away and the actuating pedal being shown in its operative position;
  • Figure 4 is a partial showing of ⁇ the structure illustrated in Figure, the actuating' pedaly being movedv tothe inoperative or retracted position;
  • Figure 5 is a view looking in the direction of the arrovvs upon the line 5--5 of FigureV 3.
  • Al tank typecleaner is illustrated in the dra-wings and is seen to comprise an outer elongated casing i.
  • Casing I is sl'idably supported by longitudinally extending runners 2; Its opposite ends are closed by end caps 3 and' il, each of which is respectively provided with areceiving seatl 5 and 6 for a dusting tool hose unit.
  • Cap fi atr the suction end oi the machine, is removable; being provided at itslower edge with a deil formed at the end of a sliding lever 9- on the underside of casing i.
  • Lever 9 is slotted and rides on a headed pin
  • At the top side of the casing is a manually operable latch i2y adaptedV to overlie the upper end of the cap and to clamp it against the end of the casing.
  • the motorfan unit comprising a driving motor 26, the casing of which is secured to an adjacent fan chamber 21 having an inlet port 28 and an exhaust port 29.
  • a pair of rotatable fans 3I which are spaced by a non-rotating guide vane element 32.
  • the forward end of the motor-fan unit 26, 21 is supported resiliently by a rubber ring 34 in a bulkhead 35 xedly secured within the casing i.
  • the rearward end of the unit is supported by a second rubber ring 36 in a bulkhead member 31 also secured in easing I.
  • Member 31 is perforated, as indicated at 38, and cooperates with a removable perforated cup element 39 to form a final ilter chamber 4I within which is positioned any suitable ltering air-permeable material which may, if desired, be impregnated with a volatile odorizing substance.
  • Electric current to the motor 26 is carried by leads 46 which enter through the casing I via the manually operable switch 41 which forms one end of the iiexible handle 48.
  • an operator-operable mechanism wliich includes a foot pedal 5I pivotally carried at the end of a longitudinally slidable square rod 52 which extends from within the casing I into a recess 53 formed in the eX- terna1 underside thereof. Rod 52 passes from the casing through a suitable sealed joint indicated generally at 54.
  • Pedal 5I is normally in the retracted position, illustrated in Figure 4, as a result of its lower end being connected vby a pin 55 to the slotted end of a connecting link 56.
  • link 56 is pivoted to the underside of the casing I at 51 and the lever 9 pivotally connects thereto at 58 a short distance from the pivot point 51.
  • the lever 9 is pulled outwardly by the cooperation of lip 1 with the cup 8 at the end of lever 9 and the link 56 is pivoted in a clockwise direction, as viewed in Figures 3 and 4, and the pedal 5I is moved into the inoperative position shown in Figure 4.
  • lever 6 is released and the spring I I pulls the link 56 in a counterclockwise direction.
  • the link 56 as it pivots from the position of Figure 4 to that of Figure 3, forces the end of the pedal 5I carrying pin 55 inwardly and moves the pedal into its outer operative position as shown in Figure 3.
  • the inner end of the square rod 52 is formed as a cylindrical extension 6I which is slidingly supported by a support 62 secured to the bulkhead 35.
  • a coil spring 63 encircles the extension 6I of the shaft between the bulkhead 35 and a pin 64 at the outer end of the shaft and at all times exerts a force which urges the shaft 52 inwardly so as to hold the lever 5I at the upper or left end of the recess 53, that is, in the position illustrated in Figures l, 3 and 4.
  • a force upon the pedal 5I effects the movement of the shaft 52 and the compression of the spring 6I.
  • To transmit this force to the bag-supporting ring I6 there is provided a sloping sided pivoted pawl 65 carried by a pin 6l) on shaft 52.
  • a coil spring 66 is connected to pawl 65 and to the underside of shaft 52 and at all times exerts a pivoting force which tends to move the pawl 65 in a counterclockwise direction, as viewed in Figure 1, to the extent permitted by the pin 61 to which the spring 66 is attached.
  • a lever arm 1I Fixedly mounted upon the arm-carrying rotatable shaft 2I is a lever arm 1I which carries a roller 12 at its outer end which is positioned as to contact the sloping or inclined side of pawl 65. That element moves toward the roller 12 in the movement of the shaft 52 under the actuation of a. force applied to the pedal 5I moving it to the right as viewed in Figures 1 and 3. This direction would be downward with the machine tilted on its end. As the pawl moves the roller 12 is forced upwardly along its inclined surface effecting the rotation of the shaft 2
  • the lever arm 1I is so positioned and is of such length that as the roller 12 travels up the inclined edge of the pawl 65 it finally rides over the top thereof at which time the force which has been stored in the spring 24 by rotation of shaft 2I accompanying the pivoting of the arms I8 is released and the arms I6 and I9 move violently in a counterclockwise direction, as viewed in Figure l, thereby moving the bag ring I6 toward the left to jerk the bag taut. Any collected foreign material is vibrated loose from the bag surface by this shaking action.
  • the shaft 52 together with the pawl 65 can continue toward the right as viewed in Figures 1 and 3 until the pedal 5i reaches the end of the recess 53 at which time, if the operator-exerted force is released, the shaft and pedal move back to their original position, that illustrated in Figures 1 and 3, under the urging of the spring 63.
  • Pawl 65 moves under the roller 12, pivoting downwardly as it does so, and extends the coil spring 66 which immediately snaps it back to its normal and illustrated position upon passing by the roller.
  • the operation of the cleaner constructed in accordance with the present invention may be briefly described as follows: The machine is placed in operation, a suitable dusting tool hose unit being connected to the inlet or suction port 6 in the removable end cap 4. Upon the closing of the manually operable switch 41 electrical current passes through the driving motor 26 and the fans 3
  • This force results in the movement of theshaft 52 and the pivotal movement of the bag-carrying arms i8 and I9, as described, and the subsequent snapping action on the bag under the vactuation of the coil spring 24 as previously described.
  • the operator will release the pedal 5I permitting it to move upwardly under the actuation of the coil spring 63 on the shaft. 52 and will repeat the downward force a plurality of times with the result that all foreign material lcollected upon the bag surface is dislodged and falls through the open end of the machine to collect upon the supporting surface.
