Definitions

  • the present invention relates to electric floor polishers and more particularly to a unitary supporting bracket for a switch, switch actuator and handle control for the appliance.
  • An object of the invention is to provide a single metal bracket for supporting the handle control, switch and switch actuator on the body of the floor polisher. Another object is to provide a bracket for supporting a switch and switch actuator, both of which have a common reference point on the bracket to reduce manufacturing tolerances whereby efficient operation of the switch is assured. A further object is to provide the aforesaid bracket with a shaft for attaching a propelling handle, the axis of such shaft serving as the common reference point to reduce the number of manufacturing tolerances on the parts supported on the bracket.
  • FIGURE 1 is a side elevational view of a floor polisher embodying the invention
  • FIGURE 2 is a broken view partly in section showing the bracket and handle bail

  • the other bail arm 33 is rotatably supported on one end 34 of a rod 35 arranged in axial alignment with the shaft 21 and the rod 35 is provided with a fiat portion 36 which rests on the body at 37 and is rigidly secured thereto by a screw 33 threaded into the body.
  • the bail arms 31 and 33 are respectively retained on the shaft 21 and rod 35 by an angular member 39 having a portion 40 abutting one end of the shaft 21 and the rod 35, and another portion 41 is welded to a threaded boss 42 which extends downwardly through the lower wall 43 of the motor housing and is secured to the body 10 by a screw 44.
  • a coiled compression spring 45 is arranged about the shaft 21 and has one end 46 seated against the bracket leg 18 and the opposite end 47 bears against a pressure plate 48 which abuts a friction washer 49 nested in a recess 50 of the switch actuator 25. Rotation of the pressure plate 43 is prevented by an offset portion 51 provided with a recess 52 which receives a rod 53 rigidly mounted in the bracket legs 18 and 19.
  • the spring 45 exerts a force between the two bracket legs 13 and 19 to dampen vibrations between the body 11 and handle 13.
  • a control for the handle 13 which comprises a lever 55 and a sector 56.

  • the pawl 64 also receives the sector lug 558 to limit movement of the handle 13 to its lower substan tially horiozntal position.
  • the lever arm terirdnates in a hook 655 on which is seated one end of a tension spring 66 the opposite end of which is connected to a hook 67 formed on the bracket leg 19.
  • the spring 66 at all times urges the lever 55 to move in a clockwise direction about the pin 6a to position the pawl 64 to receive the sector lugs 57 and 58 to control movement of the handle 13.
  • Counterclockwise movement of the lever 55 is limited by a lug 63 on the lower lever arm -59 engaging the sector 55 as shown in FIGURE 4.
  • a switch 79 is supported on the bracket leg 19 by two bolts '71 projecting through openings in the leg 19.
  • the switch is provided with two leads 72-73 for connection with the motor and conductor cord 14 in a manner well known in the art.
