Abstract
461,491. Vacuum - cleaner nozzles. ELECTROLUX, Ltd. June 30, 1936, No. 18130. Convention date, July 8, 1935. [Class 8 (i)] In a nozzle for vacuum cleaners including a nozzle body having a suction mouth of variable size and pivotally connected to a handle or suction tube, the effective suction mouth is progressively variable between two predetermined sizes by means of the handle by relative sliding movement between said handle and the nozzle body while the latter is maintained in its operative position, the angular position of the handle relative to the flow having no influence on the adjusted size of said mouth. In one form, Fig. 2, 3, a member 16 is mounted between end elements of the main nozzle body 17 so as to be movable vertically relative thereto, the member 16 being pressed upwardly with respect to the main body 17 by springs and its vertical movement being limited by pins ; the nozzle is provided with a central opening 23 and in this are mounted two pivoted plates 24 ; in the position shown in Fig. 2, the lower edges of the plates lie against the edges 26 of the normal suction mouth 27 so that the maximum suction opening is provided. On depressing the handle the member 16, which is pivotally connected to a part 15 communicating with the suction hose, is moved down so that inclines 28 formed on it, cause the lower edges of the plates 24 to approach each other, so diminishing the suction opening. When the member 16 is fully depressed it closes the non-adjustable openings 27 provided on each side of the central opening 23 so that suction is now confined to said central opening. On releasing the handle the member 16 is returned by the springs to its uppermost position, and the plates 24 are returned to their vertical positions by springs 29 secured to the member 16. In a modification, Fig. 7, adjustment of the suction opening is effected by rotation of the handle. A member 34 pivotally mounted on the shoe plate 31 and connected to the suction tube contains a cylindrical member 37, the members 34, 37 having registering openings 36, 38 ; a sleeve 44 receives the suction tube or handle and has a screw A engaging a groove on the part 34 so that it can rotate but cannot move axially ; the sleeve 44 is internally threaded to engage a member 39, a groove 46 on which is engaged by a lug 45 on the member 37. Rotation of the handle thus causes axial displacement of the member 39 which rotates the member 37 relative to the member 34 ; the size of the suction mouth defined by the openings 36, 38 is thus varied. An indicator may be provided to show the size of the nozzle opening. The plate 31 may be dispensed with. In all forms, the suction openings may be large in the centre and decrease in width towards the ends as shown in Fig. 8.
