Definitions

  • This invention relates to suction cleaners and is particularly concerned with cleaners for rugs or similar flat pile fabric surfaces.
  • nozzles be provided having a more restricted opening such that the air velocity moving therethrough is greatly in excessof that common to the normal elongated opening and it has further been proposed that such restricted opening be provided with lip modifications such as serrations which provide for an agitation of the pile of the fabric being cleaned so that the suction may become more effective. And it has further been proposed to provide rakes or combs with teeth-like formations which may engage and remove hairs, threads, and the like from enmeshment with the threads of the pile fabric.
  • Cleaners formed in line with the above proposals are effective for intense cleaning of rugs and the like but their continued use subjects the surface to deterioration due to friction and agitation in bending and turning the bristles of .the rug and it is therefore not desirable to con tinuously use such nozzles on the entire rug surface.
  • nozzles which combine an elongated smooth lipped nozzle opening with a separate more restricted opening provided with a comb or rake or the like, such nozzles providing for the selective use of either of the openings.
  • Such nozzles require a manipulation by the operator in order to selectively provide for the application of suction to one or the other of the nozzle openings and/or to apply the selected opening relation to the surface being cleaned.
  • the present inventive concept provides a rug cleaning nozzle having a single suction opening the major portion of the lip of which is of smooth configuration and the dimension of which is such as to provide for the suction normally ving action at the will of the operator.
  • the inventive concept further embraces the provision of means substantially automatic in effect for reducing the area of the opening and for moving to operative position a comb in such a manner that the normal physical reaction of the operator to an area requiring intense cleaning will adjust the nozzle for such type of cleaning.
  • a further object of the invention is to provide a cleaning device in which the suction area may be automatically reduced without specific manual manipulation of valves or similar controlling means.
  • Further object of the invention is to provide a cleaning nozzle with a comb or the like which may be selectively actuated for application to the surface to be cleaned without specific manual manipulation or adjustment of the nozzle.
  • FIG. 1 Further object of the invention is provide a suction nozzle with means automatifillyre sponsive to the pressure applied by an operating handle for adjusting the nozzle for intensive cleaning action.
  • Fig. 1 is a perspective view of one embodiment of the present inventive concept
  • Fig. 2 is a bottom plan view of that form of the invention shown in Fig. 1;
  • Fig. 3 is a vertical transverse sectional view taken on lines 3-3 of Fig. 2 with the nozzle parts arranged for normal mild cleaning action.
  • Fig. 4 is a similar view of a nozzle inposition for intensive and concentrated cleaning action.
  • the nozzle body comprises a central hollow housing ill and extending side arms II.
  • the lower surface of both the housing It and the arms II are open to form a suction opening having an enlarged central portion l2 and outwardly extending narrow elongated side openings l3.
  • openings l2 and I3 jointly form a long suction opening the lips of which are smooth except for the provision of serrations H on the forward lip adjacent the central enlarged opening l2.
  • Suction is preferably applied to the nozzle through a hollow handle or wand l5 which constitutes the actuating and controlling member for the nozzle.
  • the wand I5 is received within a socket it which is outwardly flared adjacent the housing It and has applied thereto a semicylindrical bearing member H which is slidably received upon the cylindrical outer surface It of the central housing ill of the nozzle.
  • the socket I6 is itself pivoted with respect to the nozzle body by a pair of socket ears l9 which are integral with the socket and extend inwardly within the housing l0 and are pivotally mounted upon levers 20 by means of socket fulcrum pins 2
  • the member I1 is not rigidly secured to the socket l8, but is formed with an opening through which the ears it pass with suilicient clearance to permit limited movement of the socket relative to the bearin member 11.
  • a spring 24 is compressed between the socket and the bearing member in order to maintain the latter in contact with the surface l8.
  • the forward ends of the levers 2U terminate in the valve plates 25 which move through valve guide grooves 26 on either side of the enlarged opening l2.
  • the arrangement is such that when the levers 20 are pivotally moved from the normal position of Fig. 3 to the intense cleaning position of Fig. 4 the valve plates interrupt the flow of air to the enlarged opening l2 from the narrow elongated side openings [3. thus confining the suction action to the central enlarged opening l2.
  • the levers 20 also carry mounted therebetween a comb or the like which is preferably formed as a cylindrical shell mounted upon a carrier bar 28, the ends of which are secured to the levers 20.
  • the comb itself is provided with apertures which encircle teeth 29 so that when the comb is in operative position the teeth will act to engage fine threads and hair, lifting them from the pile of the fabric so that they may be subsequently entrained by the high velocity air flow through the resiz'icted opening I2.
  • the relation of the comb 21 with the valve plates 25 is such that when the levers 20 are moved in clockwise direction against the force of the springs 23 to position the valve plates across the entrance of the opening 13, the comb will be moved to a position in the plane of the lips of the nozzle so as to be effectively positioned for cleaning action.
  • pivotal movement of the comb has a rearward component as well as a downward one, thus moving the comb out of the suction path so the width of the path h; increased to permit the passage through the nozzle of the enlarged pieces of foreign matter restricted area and as a result of the normal te- ,comb has been used to identify the means for engaging and disentangling surface litter such as hair s, textile fibers and the like from the piles of a rug or similar floor covering.
  • the term is here used in its broadest sense and refers to a general class of such instrumentalities and embraces flexible pile agitating means such as brushes or the like which will accomplish this purpose.
  • valve means comprising a pair of valves supported on arms pivotally mounted within said body and movable to position the valves across the suction opening to confine the suction to a limited section of the opening, a wand receiving coupling having arms pivotally mounted upon said valve carrying arms, and spring means for normally retaining said valve carrying arms in inoperative position.
  • valve means comprising a pair of valves supported on arms pivotally mounted within said body and movable to position the valves across the suction opening to confine the suction to.
  • a wand receiving coupling having arm pivotally mounted upon said valve carrying arms, and a comb carried by said valve carrying arms and movable therewith to operative position when said valve carrying arms are so moved.
  • valve means comprising a pair of valves supported on arms pivotally mounted within said body and movable to position the valves acrossv the-suction opening to confine the suction to a limited section of the opening, a wand receiving coupling having arms pivotally mounted upon said valve carrying arms, spring means for normally retaining said valve carrying arms in inoperative position, and a comb carried by said valve carrying arms and movable therewith to operative position when said valve carrying arms are so moved.
  • a hollow nozzle body having an elongated suction opening therein, lever means pivotally mounted within said body, valve means comprising a pair, of spaced valves movable by pivoting of said lever means to position the valves across said suction opening for confining the suction to a limited section of the opening, and-a wand receiving coupling pivotally mounted on said lever means.
