WILLIAM .1. cLEnEN'rs, orciarcaeo, ELINOIS, ASSIGNOR.TO ennumrrs me. do, or cnrcaeo, rumors, A CORPORATION or ILLINOIS 'cmnmo MEMBER FOR vacuum cnmnnas Application filed January 28, 1928., Serial No. 248,856.

My invention relates to a cleaning attach ment for use with vacuum cleaners and is par- "ticularly applicable to vacuum cleaners in which a downwardly and forwardly projecting nozzle is associated with aim and motor casing for conveyance along the suring attachment in position;

elevation showing the cleaning attachment face to be cleaned. One object of my invention is the provision ofa cleaning attachment removable from the nozzle. Another object is the provision of such'an attachment inwhich both a brush. and a bufier or polishing member are associated. '-Another object is the provision of a'reversible cleaning attachment for association with a vacuum cleaner,

nozzle. Other objects will appear from time to time in the course of the specification and claims.

I illustrate my invention more or less diagrammatically in the accompanying drawings, wherein- Figure is a side elevation ofthe casing with parts in section, illustrating the clean- Figure 2 is a front elevation pf the clean- Figure 3 is a View from below of the suction nozzle with the attachment'in position. Figure 4 is an enlarged section taken. on the line 44 of Figure 2.

Figure. 5 is a section along the line 55 of Figure 2; g

Figure 6 is a fragmentary sectional side in reversed position; and

Figure7 is an enlarged section along the line 77 of Figure 6. e

Like parts are indicated by like symbols throughout the specification and drawings.

A is a motor casing adapted to contain a motor rotatable on a horizontal axis, the axis being substantially perpendicular to the suction nozzle. A is a handle bail and A the handle whereby the vacuum cleaner may be moved across the floor. I 1

B is a bracket supported at the bottom of -the rear of the motor casing A. Pivoted to it is the roller supporting lever B to the opposite end of which is rotatably secured the and through the channels G bristles G Along the opposite edge of each such body, similarly clamped between the lent bufiin the fan casing upon which is rotatably mounted the fixed supportin roller C, it being understood that there is a racket and .a roller at either side of the bottom of the fan casing.

D is a suction inlet terminating in an extended suction nozzle D with thejslightly expanded lips D. It will benoted that the loweror floor engaging nozzle portion 1) is widely ext-ended as compared tothc relatively narrow inlet portion D, the widely extended portion being closely adjacent the floor.

The suction inlet D extends from the nozzle to a substantially. cylindrical projection E from the center of the fan casing, the axis of the said projection E being upwardly inclined in relation to the horizontal axis of the motor fan casings. 1 1 1 V G G are a pair of brush elements which material, which are provided with opposed metal channels G engaging the opposite sides thereof, being secured thereabout, for example by the rivets G Along one edge of each brush body, projectingoutwardly channels G is a stri of felt, or any equivaor polis ling member G. I The two rush elements are joined together are a plurality of by the arcuate spring yokcs H, the arcuate" portions of which are adapted to be compressed between the lips D of the nozzle 1).

The arcuate spring yokcs are rotatably secured to the brush elements G, for exampleby the bolts H provided with the nuts H In order to hold the yokes in a given adjustment, and in order to permit them" to be reversed, in order to reverse the osit'ion of the elements G, I provide latera 1y extending spring latch elements H fixedly associated with the yokes, they in. turn being provided with projections- H adapted .to

penetrate apertures H. in the elements G or the metal channels G Theends of the springs are inclined away from the brush bodies as at H in order to permit access to the finger. When it is desired to reverse the direction of the brush element the; spring yokes are adjusted, this being accomplished by moving the spring members H to disengage the projections or studs H" from the apertures at one side of the center about which each yoke is rotated and the studs engaged in the aperture on the opposite side of the center, said operation requiring rotation of the yokes on their centers through an angle of substantially 180. we

It will be realized that whereas I have shownand described a practical and operative device, nevertheless many changes might be made in the size, shape, number and disposition of parts without departing from the spirit of my invention. I therefore wish my description and drawings to be taken as in a broad sense illustrative and diagrammatic rather than as limiting me to my specific showing.

The use and operation of my invention are as follows:

I provide, for use with a vacuum cleaner of the type herein described and shown a reversible brush and polishing element consisting of a brushbody positioned at each side or edge of the lateral elongated nozzle.

The vacuum cleaner may obviously be used without such attachment if desired. Where a surface covered with lint or threads is being cleaned, or where there is a great deal of dust and dirt in the surface, as where a carpet has become encrusted with mud, the brush attachment is used, the brushes serving to agitat-e the dirt orroll up the threads and lint, whereupon the material so released from the carpet or other surface is drawn through the fan and exhausted into the bag C 011 the other hand when a smooth surface is being cleaned or dusted as for example a wax or polished floor the brush bodies are reversed and thefelt or buffer is directed against the surface to be cleaned. Thus not only is the surface cleaned and dusted, but it may be polished as well.

The adjustable rear roller 18 serves to adjust the height of the nozzle and the cleaning element from the floorto suit the particular conditions met.

I claim: I

1. For use with a vacuum cleaner, a dctachable cleaninrr member including a plurality of brush bodies and means for supporting them along the cleaner nozzle, said bodies being provided with cleaning elements on opposite facesthereof, said supporting means including adjustable nozzle engaging members and means for selectively cleaning elements on either face ofthe 7 body may be operatively associated with the nozzle.

2. For use with a vacuum cleaner, a demeans for normally holding them against movement in relation to the brush bodies, comprising latch elements, associated there with, having detent elements adapted to penetrate the brush bodies to maintain the nozzle engaging members in adjusted position, the bodies being apertured to receive the penetrating elements.

3. For use with a vacuum cleaner, a double faced cleaning member and a. means for detachably securing it to the cleaner, includ- 1ng U-shaped spring members adapted to penetrate and exert gripping pressure against the vacuum cleaner nozzle, said springs including arms upwardly extending exteriorly of the front and rearedges of said nozzle, said cleaning member including a plurality of brush bodies adapted to be pos tioned upon said arms exteriorly of said nozzle to the front and rear thereof, said spring members being rotatably adjustable in relation to said brush bodies, for operatlvely associating either cleaning face of the cleaning member with the nozzle, and means for normally holding said spring members against rotation in relation to said brush bodies. 0 4. For use with a vacuum cleaner, a cleaning member support provided with opposlte cleanlng element carrying faces and adapted to engage and grip a laterally extended vacuum cleaner nozzle, said support dncludin arms upwardly extending exteriorly of the front and rear edges of said nozzle, said spring members being rotatably ad ustable in relation to said cleaning memher support for operatively associating either of two faces thereof with the nozzle, and means for normally holding said spring members against rotation in relation to said brush bodies.

State of Illinois, this 14th day of January,
