Definitions

  • This invention relates to improvements in' sucr-l tion cleaners.
  • the suction is. created by a motor-driven fan in a portable cas I ing and connected to the casing is a flexible hose having atits outer end an open-mouthed nozzle which is moved over the carpet or other surfaceto becleaned so thatthedust is extracted by the suction and collected in a bag in the casing.
  • a suction nozzle will pickup surface dirt and dust from a carpet or the like, but does not extract dust embedded in the pile of the carpet, and for this reason various forms of beating mechanism have been fitted to cleaners to beat 15 the surface" being cleaned and disturb or loosen the dirt and dust which is then picked up by the suction.
  • the beating mechanism is commonly mounted within the nozzle and driven from wheels travelling on the carpet or the like.
  • the object of my invention isto provide an improved form of suction nozzle for cleaners whereby a much higher degree of efilciency is obtained than is possible with an ordinary suc-@ tion nozzle, and-whereby dirt and dustembedded II in a. carpet or like surface can beextracted without any risk of damaging or wearing the surface.
  • a suction nnzzle' is divided by one, two or more partitions into openmouthe'd compartments which are alternately put I into communicationwith and cut oil from the suction pipe leading to the cleaner by means of a rotary or reciprocating valve or valves, and the alternation of the suction in the compartments may if desired be employed to operate oneor 8
  • Figure 1 is a front elevation of the nozzle.
  • Figure 2 is a plan of the nozzle.
  • Figure 3 is an end elevation.
  • j 50 Figure 4 is an invertedplan.”
  • Figure 5v is a longitudinal vertical section .of the nozzle showing the moving parts in a neutral position.
  • Figure 6 is a similar section showing theparts 55 inone extreme position.
  • Flgure '7 is a similar section showing the parts castinghaving in its bottom face a longitudinal rectangularopening divided intotwo parts and 4 vby a tr'ansverse partition 5.
  • Asmaller opening in the upper face of the body is normally closedby a flanged cover 5 which is hinged to the body at one end e secured atth e other end l bya clip.
  • Thecover oarriesthe valve and the oscillating operating member as described below so that these parts'can be readily inspected and cleaned by opening the cover 0;
  • An opening Tin the rear wall of the body leads into aswivel or other convenient connection O forQreceiving the suctlonhose of a vacuum cleaner. 1
  • valve is pivoted about a transverse pin li on the cover 6 directly above the apex 'o'fjthe'suction chamber so that when the opening ii in one vside of the chamber is closed by the blade I 3 of the valve thefother blade I4 is spaced fromj the opening in the otherside of the chamber and vice' versa.
  • the width ofithe oscillating 'm'ember is such that it just clears the back and'front of the' -body-an'd the arms l6, l1 are of such a length that their ends 'justclear' curved surfaces I! 'at the ends of 'theupper part of the body, these surfaces forming'alcs about the pivot pin I! as a-centre, 'so that the arms make asubstantiallyair-tight seal with the walls of the compartments in which theymove;
  • the central part ofthe upper faceofthe oscillating' member is spaced a short .distance from the underside'of the'cover 6 so that air can pass through this space as the member oscillates.
  • strikers 20 Secured to or integral withthe ends of the a arms l6, I! are strikers 20 for engagement with of the suctionchamber lead into the two open into channel section and the beater is guided on the heaters, and these strikers may be weighted to increase the force of the blows.
  • oscillating member and valve blades adjacent to their pivot to exclude dust from the pivot, and the verve blades may if desired be covered with fabric, rubber or similar material.
  • beater members 23, 24 Slidably mounted for vertical movement in the openings 3; l are longitudinally extending beater members 23, 24. 'Each of these beaters maybe of wood or other suitable material but in the'form' illustrated it is made from sheet metal pressed pins 25 'working in vertical slots in the sides of the beater. The beaters are considerably narrower than the openings 3, so as to leave an unobf structed partof the opening behind each beater,
  • each beater is conveniently located between the front wall of the opening and a longitudinal partition wall 26.
  • a cork or other resilient pad 21 secured in each. beater receives the blow from the end of the oscillating member and helps to reduce noise.
  • the length of the guiding slots in the beaters is such that normally the lower surfaces of the beaters lie Just below the plane of the bottom surface of the nozzle and the beaters are pressed upwardly when the nozzle is placed on a carpet or other surface to be cleaned.
  • j V The operation of the mechanism is as follows:--- 'T Assuming the parts to be in the position shown in Figure 5 and suction to be applied to the nozzle one of the valve blades, saythe blade l3, will be sucked down to close the opening Ii, in the suction chamber. The suctionthen acts through the opening i2 on the arm W of the oscillating member which is drawn down into the position shown in Figure '7.
  • the beaters apply a blow to a carpet or the like similar to that applied by a switch or cane so that anydust or dirt is effectively loos- Small strips of fabric 2! may be secured to the ened but there is no appreciable wear of the carpet.
  • the springs I 8 ensure a very rapid action of the valve and "the speed of reciprocation can be for picking up threads and toassist in stirring up and loosening dirt in'the surface to be cleaned.
  • FIG. 1 to '4 One convenient type of brush is shownin'Fig- -ures 1 to '4.- Downwardly directedbristles 28fare carried by a plate 29 which is' vertically movable on guide pins 3! on the outer surface of the frontface of the nozzle and is normally urged upwardly byfsp'ringsil to hold the bristles-clear of the surface to. be cleaned.
  • a cam member 32 pivoted on the nozzle is rotated into the position shown in Figure'l, and the cam bearing on a shoulder onthe plate 29 presses the brush downwardly to bring the'bristles into contact with the surface to'be cleaned.
  • a nozzle for a"'suction cleaner comprising a hollow nozzle body, an opening in the body for connection to asuetion pipe, a mouth opening in the body. a plurality of separated compartments in'the body leading into the mouth opening, said mouth opening having ports each communicating with a respective compartment, an oscillating valve mounted in' the body and operated bythe suction to cause the suction to be applied alternately to each compartment, a movable beater member loosely mounted in the mouth opening, and means associated with 'the valve for operatingthe beater member.
  • a nozzle for a suction cleaner comprising a hollow nozzle body, said body having an opening.
  • a nozzle for a suction cleaner comprising a nozzle body, said body having a suction outlet, said body further having an elongated suction mouth in the bottom of the nozzle divided into separate openings, two compartments in the body each communicating with one of the mouth openings, oppositely inclined partitions arranged in the body between the suction outlet and said compartments, said partitions having apertures establishing communication between the suction outlet and the compartments, an oscillating valve,
  • said valve consisting of two to connect the compartments alternately to the suction outlet, an oscillating member pivotally supported in said body, said member consisting of two opposed arms working in substantially airtight relationship with the walls of the compartments and inclined to each other at an angle greater than that between the blades of the valves, whereby the application of suction to either compartment causes the suction to act on one arm of the oscillating member which is thus rocked over and engages and rocks over the valve to cause the suction to be applied to the other compartment.
  • an elongated casing having a downwardly facing opening at each end, said openings being separated by a central transverse partition, a pair of beater elements each mounted in a respective opening of said casing, said casing having a vacuum chamber disposed centrally thereof and having port communication at each side with a respective opening, and means in said casing extending over said chamber and operable to alternately close and open said port communications and including means to cause alternate actuation of said beater elements.
  • said openings being separated by a central transverse partition, a pair of beater elements each mounted in-a respective opening of said casing, said casing having a vacuum chamber disposed centrally thereof and having port communication at each side with a respective opening, and means in said casing extending over said chamber and operable to alternately close and open said I port communications and thereby to cause alternate actuation of said beater elements, said means including actuating arms disposed to strike and depress said beaters.
  • a nozzle for a suction cleaner comprising a hollow nozzle body adapted to be connected to a suction pipe, a partition dividing the nozzle into a plurality of open-mouthed compartments, a beater member movably mounted in the mouth of valve connecting the compartments alternately in rapid succession with the suction pipe, and means operated by the alternation of the suceach compartment, an automatically operated tion in the compartments for actuating said beater members.
