,The present invention relates to suction clean-- ers in generaland particularly to improvements wi the combination of an on-thJe-floor suction cleaning unit with" a dusting. tool unit. More specifically the invention comprises an improved" tool converter and its seat upon the suction cleaner body.

, It is an object of the present invention to provide a new and'improved suctioncleaner provided with dusting tools A furtherobject' of the invention is the provision of a new and improved dusting tool converter. Still another object is the provision of a suction cleanerin combination with dusting tools which are removably attached by new and novelsecuring means. These and other more specific objects will appear upon read broken'away and'shown in section, of a modern suction cleaner 2s tlon; I v

The modern suction cleaner is a unit primarily 85 designed for on-the-floor cleaning. To increase its rangeof usefulness the cleaner is so constructed that it can be combined with dusting.

tools which make the suction created by the unit effective at a point spaced therefrom, In the 40 present invention a new and improved dusting.

tool converter is provided which is easily attached to the suction cleaner, and in particular to the suction-creating means thereof.

Referring again to thedrawing a modern suc- 46- tion cleaner is shown comprising a nozzle I, an

air passageway 2 comprising side walls and a re- I movable bottom plate which. has been removed to permit the attachment of the dusting tool con verter, a fan chamber 3, in which isrotatably 50 mounted a suction creating .fan. 4; and the ex haust outlet 5 through .which the cleaning air drawn from the nozzle iyand through the fan chamberis exhausted into the removably at: tached dust bagt. A motor casing 1 is positioned 55 immediately above the fan chamber land houses the drawing-in which a preferred embodi 4 (cl. 15 -0); k an u'nshown driving motor for the suction-crest "ing fan, the extended shaft 8 passing through the fan chamber'and into the air passageway 2 where it. is provided with a pulley 9. In the normal operation of the cleaner in on-th-floor cleaning rounds", the rotatable, agitator ii. The agitator comprises a body. provided with suitable agitating elements which contact the surface covering undergoing: cleaning. In the use'of the cleaner with dusting tools the belt is disc'onnected from the.

pulley 9 as shown inFigure'l. The cleaner body is movably supportedup n the front wheels i2.- i2 .and rear wheels I 3, IS, the latter being pivotally -means, indicated generally by the reference char-- acter II, by the use of which the nozzle may be raised'or lowered relative to the surface cover- .mounted and provided with manual adjusting mg. As in the usual suction cleaner of this type 1 a pivoted handle 15 is provided which is suitably connected 'to the cleaner body and extends upwardly and rearwardly therefrom.

In the disclosure inthe drawing the no bottom plate of the machine which completes theair passageway. from the eye of the fan chamber '3 to the mouth of the nozzle i-has been removed and the belt in has been disconnected from the driving pulley 9. The entire suction of the suction-creating fan 4 is effective at the eye i6 and, by the attachment of the dusting tools at this point, cleaning air can be drawn therethrough instead of through the nozzle I, the nor-e mal path. To accomplish this purpose the dusting tool unit isprovided with a converter member, indicated by the; reference character I1, com- An outwardly extending shoulder or latch memher I! is formed on dr secured to the body ll at a pbint adjacent the opening and extends parallel to the bottom wall of the fan chamber 3 to a pointat, which it is contacted by a spring-pressed latch member ",mounted on the bottom of the fan chamber. The latch 20 is normally springurged intolocking position as shown in Figure 2, and isprovided-with an extensionjl which is adapted to be grasped by the hand of the operator. By pulling on the element 2! the latch 20,

can be moved against the normal force of the spring to permit the downward displacement of the shoulder or latch member l9 and the consequent removal of the converter H.

To insure that the converter body will, at all times, be so placed relative to the fan chamber that the latch members l9 and 20 can cooperate there are provided two spaced lugs 22, 22 on the body which cooperate with and seat at thet'sides of a projecting shoulder 23 on the bottom of the fan chamber. With the converter member seated in place the two lugs 22, 22 are positioned at the sides of the shoulder 23 and preventrotational movement of the converter member relative to the fan chamber, and also give a clear indication of how the two should be secured together. There is also secured to the inner wall of the body I! of the converter a leaf spring member 24, the upper end of which extends upwardly and over the top of the body I! and overlies the inner surface of the fan chamber wall adjacent the opening l6, Member 24 cooperates .with shoulder l9 and the spring-pressed latch member 20 in preventing the downward displacement of the converter member from the fan chamber opening and'iIi fact resiliently draws the body to the fan chamber.

The converter member versely extending conduit or passageway 25 which is adapted to receive and seat the cleaner end of the dusting tool hose 26. Aspring-pressed detent 21 is provided which detachably secures the two parts together.

In altering the suction cleaner from an on-thefloor unit to an off-the-floorunit the operator removes the unshown but common bottom plate from the side walls of air passageway 2 and disconnects the belt I 0 from the driving pulley 9. He then places the converter member I] adjacent the eye l6 of the fan chamber with the leaf spring member 24 overlying the inner side of the chamber wall of the adjacent eye and with the two lugs 22, 22 spaced at the sides of the locating shoulder 23. With the converter member so positioned the shoulder or latch l9 extends in close proximity l1 includes a trans-' *for off-the-floor cleaning.

I claim:

1. In a suctioncleaner; a fan chamber having an. eye, a dusting tool converter having a body formed with an opening and a conduit, said body being removably seated on said fanchamber with said opening alined with said eye, cooperating means on said chamber and body to aline said converter with said conduit extended in a particular direction, a resilient mg on said body at said opening overhanging the interior face of said Upon releasing the member 2| the spring fan chamber adjacent'said eye and functioning todraw said body to said chamber, and cooperating latch means on said chamber and body spacedrfrom said overhanging lug to retain said parts in operative relationship.

2. In a suction cleaner, a fan chamber having an eye, a dusting tooliconverter having a body formed with an opening and a conduit, said body beingremovably seated on said fan chamber with said opening alined with said eye, cooperating means on said chamber and body to aline said converter with said conduit extended in a particular direction, a leaf spring on said body at said opening extended thru said eye and into contact with the, chamber wall, an outwardly extending latch member on said body spaced cir-. cumferentially around said opening from said leaf spring, and a manually operable springpressed latch on the bottom of said fan chamber 40 underlying said outwardly extendinglatch to removably loci; said converter to said chamber.
