  • ELECTRIC POLISHER FOR SMOOTH VERTICAL WALLS SUCH AS WINDOW GLASS Filed April 9, 1968 3 Sheets-Sheet 3 3 no 2 z 4 25 103 United States Patent 3,501,798 ELECTRIC POLISHER FOR SMOOTH VERTICAL WALLS, SUCH AS WINDOW GLASS Ennio Carraro, Via Roma 305,
  • the object of the invention is to provide a light-weight electric polisher of smooth vertical surfaces provided with a hood and a peripheral yieldable skirt tightly adhering against the surfaces to be polished.
  • Said polisher which will be briefly called window glass polisher is a light-weight polisher adapted to be readily shifted along plane vertical glass surfaces to be cleaned and polished by the combined action of rotating brushes and of a cleansing liquid, means being provided for spraying the liquid against the walls to be polished, preventing its downfiowing, removing the sprayed liquid from the cleaned wall, whirling same in the air enclosed under said hod and sucking such polluted air, if necessary after having comminuted the liquid droplets and subjected same to the action of a heater for transforming the liquid into vapor, before discharging same outside of the apparatus by blowing same off through an outlet opening of said hood.
  • FIGURE 1 is a diagrammatical top plan view with parts in section of a window glass polisher according to the invention
  • FIGURE 2 is a top plan view of the same polisher, without cover or hood;
  • FIGURE 3 is a vertical section on line IIIIII of FIGURE 1;
  • FIGURE 4 is a vertical section on line IV-IV of FIGURE 1;
  • FIGURE 5 is a horizontal section on line VV of FIGURE 4.
  • FIGURE 6 is an enlarged section through the lower brushing and packing skirt
  • FIGURE 7 is a vertical section through one of the rotating brushes and FIGURE 8 is a perspective view of one of the brushes, dismounted from the apparatus.
  • the window glass polisher as shown in the drawings comprises a casing 1 composed of a base plate 2 and hood or cover 3 fastened thereto.
  • a tubular handle stick 4 is swingably fastened by means of its uCe forked ends 5 to two side pivots 6 mounted onto the hood 3 (see FIG. 1).
  • Stick 4 is preferably composed of a plurality of tubular sections fastened together.
  • the casing 1 is provided at its outer edge with a projecting elastically yielding striping and packing skirt 7 which extends along the whole periphery of the casing and is composed of an outer felt brim or lap 107 and of an inner layer of brush filaments 207 (see FIG. 6). Said packing skirt 7 is clamped between two superposed border sections 103 and 103 of the hood 3.
  • each shaft 8 9, 10, 11 and 12 are rotatably mounted so as to project downwardly and carry at their projecting ends each a substantially cylindrical brush 13. Said shafts are rotated by an electric motor 14 which through a speed-down gear 15, 16 drives the central brush shaft 8 onto which two superposed pulleys 108 and 208 are keyed which through a pair of driving belts 17 and 18 drive each a pair of pulleys 109-110 and 111- .112 fastened onto the brush-carrying shafts 9-10 and 11-12.
  • an electric motor 14 which through a speed-down gear 15, 16 drives the central brush shaft 8 onto which two superposed pulleys 108 and 208 are keyed which through a pair of driving belts 17 and 18 drive each a pair of pulleys 109-110 and 111- .112 fastened onto the brush-carrying shafts 9-10 and 11-12.
  • a suction fan 20 Upon the central shaft 8 there is mounted the blade rotor 19 of a suction fan 20, the outlet of which is connected to an opening 21 in the hood and it thus open to the outer air.
  • the suction side of said suction fan 20 is connected through a pair of suction ducts 22 with a pair of suction openings 23 provided in the base plate 2.
  • a drop breaking strainer 24 and an adjoining electric resistance 25 are mounted in each duct 2 .
  • a tank 45 for a cleansing liquid is mounted, which through a suction duct 26 is connected with a compressed-air spray nozzle 27 mounted onto the lower side of plate 2.
  • Said cleansing liquid may be filled into the tank through a cap-closed neck 28.
  • an air blower 29 is mounted, the casing 129 of which is fastened to the base plate 2 by means of a stirrup 30, while the rotor 229 is fastened to an upper extension of shaft 10.
  • the pressure side of pump 29 is connected to nozzle 27 through duct 31 and is connected by means of a branch hose 32 with a pressure air outlet 33 provided in the stick 4, as clearly shown in FIGURES 1 and 2.
  • Brushes 13 are dismountably fastened to the ends of brush shafts 8-12.
  • said brushes are mounted in a holder 34 provided with a hub 35 provided with a recess having a non-circular cross section (in prac tice, the recess has two opposite flat walls) which is fitted onto a correspondingly shaped end 37 of the brush shaft 8 (see FIGURES 7 and 8).
  • the brush holder 34 is also provided with a pair of diametrically opposite snap teeth 36 which, when the brush holder 34 is fitted onto its shaft, snap into a peripheral groove 38 of the shaft and thus prevent any axial slipping of the brushes.
  • the teeth however, have rounded ridges, so that they can come out of groove 38, when an adequate pull is exerted on the brush holder 34.
  • the end of shaft 8 is frusto-oonical for rendering the fitting of the burst holder easy and for centering purposes.
  • the electric wires 39 which feed the motor 14 and the electric heating resistances 25 pass through one of the fork arms of the stick and lead to a switch 40 on the stick 4.
  • the glass polisher which is constructed very light, is pressed against the glass to be cleaned and polished, as shown in FIGURE 4, so that the peripheral skirt 7 and the brushes 13 tightly adhere on the glass and with the motor 14 on, the appliance is guided along the window glasses to be cleaned and at the same time the cleansing liquid from tank 45 is sprayed against the glass surface from time to time, under the control of the operator.
  • the peripheral felt skirt 7 reinforced by a row of brush filaments a closed chamher is formed under the hood.
  • an air outlet 33, FIG. 1, is provided on the stick.
  • Electric cleaner and polisher having an operating stick, particularly for polishing smooth walls, such as window glass and the like, comprising a plate, a hood having an opening at its top, fastened above said plate and provided with a circumferential skirt of felt and brush filaments extending downwardly beyond said plate and adapted to adhere with a tight fit against the smooth walls; an electric motor provided with a motor shaft under said hood; a central vertical shaft; a step-down gear connecting said motor shaft to said central vertical shaft; a plurality of peripheral vertical shafts around said central vertical shaft; a rotary brush mounted to each vertical shaft, beneath said plate; means on said central shaft for driving each of said peripheral shafts; a suction fan under said top opening of the hood and discharging therethrough polluted air from below the hood; means for driving said suction fan from said motor shaft; a blower; means for driving said blower from one of the peripheral vertical shafts; a liquid tank; at least one spray nozzle under said plate; means connected to the blower for conveying the liquid from said tank
  • step-down gear is a worm and worm wheel gear.
  • An electric polisher for smooth vertical walls according to claim 1 by which said central vertical shaft is provided with superposed belt pulleys and said peripheral vertical shafts are provided with belt pulleys at the height of either belt pulley of said central shaft, and a transmission belt drivingly connecting one of the pulleys on the central vertical shaft with one pulley on at least one of the peripheral shafts.
