  • a transverse shaft 21 rotatably carries the wheels 23 on bracket 26 at the rear thereof, the bracket being at al1 times spring-pressed downwardly by coil spring 28 in a manner which tends to lift the rear of the machine.
  • a catch comprising a vertically extending arm 3l with a hook at the upper end thereof is carried by one arm of bracket 26 and is adapted to engage an abutment 32 to limit the angular movement of the bracket 26 relative to the cleaner body under the actuation of the coil spring 28.
  • a downwardly extending bracket 33 On the underside of the cleaner body at a point immediately over the rear wheel-carrying shaft 21 is a downwardly extending bracket 33 provided with a plurality of vertically spaced outwardly extending rigid pins 34 which are,accordingly at various distances from the wheels 23 and so shaft 21.
  • a foot lever 36 formed as a bell crank is pivotally mounted upon the extended end of shaft 21 atr one side of the pair of wheels 23 and, as is clearly illustrated in the drawings, extends outwardly and to the side of the adjacent cleaner side iwall I3.
  • the upper end of the bell crank arm, that is foot lever 36 is formed as a cam surface 31 the outer or upper end of which is at a greater radius from the pivotal axis, comprising shaft 21, than is the inner or lower end thereof.
  • Cam surface 31 is adapted to engage selectively the pins 34 which are carried by the depending bracket 33 when the foot lever pivots in a counter clockwise direction from the position illustrated in Figure 1 into which it has been depressed by the operator.
  • the movement of the cam surface 31 past the pin 34 is prevented by the lower or inner end thereof being slightly hooked.
  • YA coil spring 38 on the rear wheel shaft 21 acts at all times to pivot the lever 36 in a counter clockwise direction, as shown in Figure 1, and tends to secure the pin which is in engagement with the cam surface 31 in seating relationship with the hooked end thereof.
  • the foregoing comprises the construction of the cleaner constructed in accordance with the present invention.
  • the invention is applicable to a cleaner with or without an agitator and in the embodiment illustrated a rotary agitator 4I of the usual and well known type embodying rigid beater elements and flexible brush elements has been shown as rotatably mounted within the cleaner nozzle where it is driven by a, power-transmitting belt 42 which connects to the lower end of the motor drive shaft 9.
  • the invention is as applicable, however, to a machine which is unprovided with an agitator.
  • the operation of the cleaner constructed in accordance with the present invention is as follows.
  • the cleaner being placed upon a surface covering which is to be cleaned, the operator depresses the foot lever 36 thereby moving it from a position as illustrated in Figure 3 to that illustrated in Figure l.
  • the coil spring 28 forces the rear of the machine upwardly pivoting the body rabout the front supporting wheel shafts 22 as an axis.
  • the front of the machine is forced downwardly until the surface-contacting lips 2 and 3 rest upon the top plane of the supporting surface, their areas being sufficient to prevent appreciable penetration.
  • the front and rear supporting wheels are supporting the large part of the cleaner weight and have penetrated the supporting surface to a distance sufficient to give a firm foundation.
  • Three positioning pins 34 have been illustrated but obviously the number thereof can be varied as desired and as warranted by the neness of the adjustment necessary.
  • the movement of the rear of the machine has produced a lifting at the front or nozzle end thereof.
