Definitions

  • This invention relates to a combined suction-cleaning and floor-polishing apparatus of the kind comprisingv a casing formed integrally with or carrying a suction nozzle, a rotary floor polishing element or elements carried by the casing for retraction into the casing and an electric motor, carried by the casing which drives the ⁇ polishing element or elements when inthe operative position, the suction nozzle and polishing elements being each adjustable from an on-the-floor position to an off-the-oor position and vice versa.
  • suction nozzle when the suction nozzle is in the on-the-tloor position it may be either in actual contact with thel floor surface or may be slightly raised therefrom and that when in the off-the-floor position it may operate with a reducedv suction eiectv to carry away dust raised during polishing.
  • This invention concerns apparatus in which-when the polishing elements are in the on-the-iloor position the nozzle is in the oi-the-floor positionl andl vice versa and means are provided simultaneously to adjust the polishing, element or elements and the suction nozzle and to connect or disconnect, as-is appropriate, the drive to the polishing elements and the object of the present invention is the provision of an improved construction of said means-which for convenience will hereinafter be referred to briey as the adjusting means.
  • FIG. 1 is a side view partly in section of an apparatus in accordance with this invention.

  • Figure 4 is a section on the line 4-4 of Figure 1 showing a detail of construction
  • Figure 5 is a View in the direction of the arrow 5 of Figure 1 showing a constructional detail.
  • the apparatus comprises a casing, generally indicated by the reference numeral 1t), on the top of which is mounted an electric motor 11 enclosed within a housing 9'which drives a vertical spindle 12 projecting into the casing 10.
  • a fan 13, ot' any known or convenient construction, is mounted on the spindle 12 within a fan chamber 14'which forms part of the casing 1G.
  • An opening 15 places the fan chamber 14 in communication with a suction nozzle generally indicated at 16 so that, in well known manner, air is drawn through the nozzle 16 ⁇ by the fan 13.
  • the nozzle 16 has anopening 17 of generally rectangular form in plan within which rotates a brush 18" which is driven -by belt 19 from the spindle 12'. t will be noted? in Figure 1' that the spindle 12 is grooved at 20-toreceive the band 19.
  • the casing 19 is support'edon a-pair of side rollersf21 nited States Patent' 'ice 2 and back rollers 22', all of which are mounted within the casing 10. y
  • the nozzle 16 is towards the front of the casing 10and in the rear portion thereof there is disposed the polishing elements and the adjusting means therefor.
  • Each polishing element comprises a backing disc 23 which carries the bristles Zi'and eachdisc 23 ⁇ is rotatably supported by bearing 2S from a carrier plate 26;
  • the carrier plate 26 (as shown in Figures 2 and 3) is common to both polishing elements which rotate about parallel vertical axes and, as shown in ⁇ Figure 3, are arranged so that the peripheries of the discs 23 are spaced apart by a small amount and less than the diameter of the spindle 121
  • the spindle 12 is adapted, as later described in detail, to enter between the peripheries of the discs' 23 and separately to drive each disc.
  • the driving spindle 12 may be faced with rubber to engage the discs 23 or the latter may, alternatively oradditionally, be formed with a rubber facing.
  • the spindle 12 constitutes the rotary driving member referred to above.
  • the carrier plate 26 is supportedat-opposite sides by a pair of parallel links 27 each of which is pivotally secured to the casing 10T by pin 28 ⁇ and to the carrier 26 by the pin 29 (see Figure 4).
  • each-side of the carrier 26 is supported from the casing 11i by a-parallel link mechanism which permits'the carrier 26Y and the brushes 24 to be simultaneously moved in the horizontal and vertical directions.
  • the carrier plate 26 is formed on its rear edge with a pair of lugs 30 which a're connected together by a pin 31.
  • the casing 10 is formed with a boss 32 that constitutes a bearing for a ⁇ spindle 33 which passes downwardly through the casing 10 and carries at its lower'end a crank pin 34 which engagesY the pin 31 so ⁇ that with rotation of the spindle 33 from the fullL line position shown in Figure l to-the chain dotted position the carrier plate 26 is drawn rearwardly to move the polishing elements 24 from the on-the-floor position to the olf-'the-oor position.
  • a pair of springs 35 (are oneachside of a'vertical plane passing through spindle 12) has one end anchored to the casing, as at 36, and the-other end secured tol the carrier plate 26,y as at 37, the arrangement being that the plate 26 is drawn forwardly i. e. towards the nozzle 16' (see Figure 3) and to its on-the-floor position.
  • the links 27 when the polishingA elements 24 ⁇ are in their on-the-floor position arel slightly to one side of a vertical dead center position as is apparent from Figure 1.
  • the polishing elements when in their on-the-floor position support the casing 10 andl themotor 11 and the links 27 being beyond the vertical deady center position theweight of the casing 1l)l and motor 11i is applied to the'linksv 27 tendingto-move the carrier 26 towards the left as seenin Figure 1.
  • Such movement is prevented by engagement of discs 23 ⁇ - withv spindle 12 which constitutes a stop limiting the movement' of the polishing elements- ⁇ at their on-the-'oor position.
  • TheV rear wheels 22' arev vertically# adjustable so that when the polishing elementsf24" are in their on-the-oor positionl the Wheelsv 22 are raised relatively to the" casing I to ensure that they do not engage the floor during polishing.
  • the wheels 22 are lowered when the polish-- ing elements are in their off-the-floor position so that the wheels 22 engage with the oor and, in certain circumstances as later described, tilt casing to bring opening 17 close to the oor.
  • the mechanism for raising and lowering the wheels 22 is more particularly shown in Figure 1 to which reference will now be made.
  • the wheels 22 are carried by a frame 3S integrally formed with a pair of arms 39 each pivoted to the casing 10 upon alining pins dit. As is shown in Figure 3, the arms 39 branch from opposite sides of the frame.
  • Springs 4l which are located between the casing 16 and a platform 42 forming a part of the frame 33 urge frame 38 downwardly, the frame 38 pivoting about the pins 4t).
  • Frame 38 is formed with a cam surface 43 which coacts with a follower 44 secured to crank 34, the arrangement being that with rotation of the spindle 33 follower 44 is adjusted relatively to cam 43 to raise the frame 33 or to permit the springs fil to lower it, the springs 41 and cam mechanism 43 44 thus serving cooperatively as means for vertically moving said frame.
  • the cam 43 and the crank pin 34 are so disposed that when the polishing elements 24 are lowered, frame 38 and the rollers 22 are raised and vice versa.
  • nozzle 1 6 it is customary to provide adjustment for the nozzle 1 6 to take account of the different pile thicknesses of the carpets which are being cleaned and to adjust the nozzle 16 to a datum position depending upon the nature of the carpet.
  • This is provided for in the apparatus being described by having a knob 45 pivotally mounted ou the rear face of the casing 10 and carrying a square block 4o (see Figure 5). Adjustment of the knob 45 serves to rotate the block 46 the center of which is offset with respect to the axis of rotation of the kncb 4S.
  • the block 46 engages with a curved face 47 provided on frame 3S and maintained in engagement with the block 46 by springs 41.
  • crank 34 may be formed with a cam surface to cooperate with a follower on the frame 38.
  • the carrier plate is capable of movement across the casing 10 so that when the discs 23 are moved into engagement with spindle 12 the discs 23 will automatically adjust themselves to bring the spindle centrally between the discs. will be driven uniformly. It follows that by making these parts to non-precision standards the advantage referred to is obtained and the cost of manufacture is kept low.
