Definitions

  • height adjusting mechanism as it appears with' ment to be manipulated by the operator at his judgment of the varying carpet conditions may dictate, but without any guide for insuring the correctness of adjustment being made.
  • the object of the present invention is to substitute for the more'common manual adjustment, a so-called automatic adjustment wherein the height of the nozzle is governed by the pressure exerted through the handle in the act of maneuvering the cleaner over the carpet being cleaned.
  • a so-called automatic adjustment wherein the height of the nozzle is governed by the pressure exerted through the handle in the act of maneuvering the cleaner over the carpet being cleaned.
  • a further object of the invention is to provide a novel mechanism for transmitting the pressure exerted through the handle to the adjustable front wheel mounting whereby an approximately constant relationship between nozzle height and handle pressure may be maintained throughout the range of ordinary clean- 8 operations.
  • Figure 1 is a general view in side elevation of a standard type of handle-maneuvered cleaner equipped with handle-pressure actuated nozzle adjusting means;
  • Figure 2 is an enlarged view in side elevation of the cleaner body. showing the nozzle adjusting mechanism asit would function with the cleaner operating upon a bare floor or hard surface covering;
  • Figure 3 is a view similar to Figure 2 but showing the cleaner being-operated upon a carpet having a relatively thick pile and the manner in Figure 4 is a perspective view of the nozzle the body of the cleaner removed;
  • Figure 5 is a perspective view of the handle position control sector as it appears when removed from the cleaner.
  • the nozzle height adjusting device disclosed herein is applicable to any standard cleaner of the portable handle-maneuvered type, it is here embodied in a cleaner wherein the fan chamber and nozzle are included in a "single main casting I with the nozzle 2 extending transversely across the front of the main casing l and the motor 3 extending horizontally and in axial alignment with the fan chamber 4.
  • a handle 5 Forming a part of the cleaner assembly, although not having direct connection with the body, is a handle 5 having at its lower end an inverted U-shaped yoke or ball 6 straddling the motor 3 and pivotally connected at its lower extremities with the nozzle adjusting mechanism presently to be described in detail.
  • the exhaust outlet from the fan chamber 4 is at one side and opens in an upwardly direo- .tion, although not shown herein because it is located on the far side of the cleaner body.
  • the exhaust outlet from the fan chamber opens into the lower end of a dirt bag -l which extends upwardly along the handle and is supported thereby through a short extensible connection, preferably in the'form of a light coil spring 8 having detachable connection with the upper end of the handle.
  • the dirt bag is of the customary shape and construction, namely, an elongated tube of a porous woven fabric or equivalent filtering material closed at' both ends but with the upper end capable of being opened for the purpose 0 emptying the bag of its contents.
  • the dirt bag 'I' difier s somewhat from the more common arrangement in that it is sup-' ported in front or on top of the handle 5 instead of being suspended below it. And again, the dirt bag 'I' difiers somewhat from the more common arrangement in that it is sup-' ported in front or on top of the handle 5 instead of being suspended below it.

Underthese d5 ditions', the force exerted throughthe handle will It located immediately to the rear ofthe nestle 5 z and a pair of rean wheels l4.
  • This lifting force therefore, counterbalances a part of the weight carried upon the front wheels and is especially helpful during the rearward stroke of the cleaner when there would be no adjustment of the nozzle
  • the tension exerted through the bag tends to-maintain the nozzle at the same height during both strokes.
  • the tension exerted through the bag is advantageous in that it renders the cleaner body more responsive to the force exerted through the In any handle and the adjustingmechanism more sensitive to varying carpet conditions.
