KRAVOS BATTERYPowERED CLOTHES BRUSH 2 Sheets-Sheet 2 Filed March l, 1965 United States Patent() 3,316,577 BATTERY-POWERED CLOTHES BRUSH Joseph F. Kravos, Chesterland, Ohio, assignor to General Electric Company, a corporation of New York Filed Mar. 1, 1965, Ser. No. 435,835 11 Claims. (Cl. 15-23) This invention concerns a battery-powered clothes brush and, more particularly, a compact, self-powered device for effectively removing dirt and lint particles from garments or other surfaces.
Various mechanically and electrically powered devices have been proposed by the prior art for removing dirt and lint particles from clothing. Although brushes or suction air flow have been employed singly, the most effective removal of particles is accomplished by the combination of both techniques. As a Iresult, an impasse has `been encountered in efforts to reduce the size of the cleaner to a more acceptable compact package by the necessity of including a vacuum-inducing fan member in addition to a rotating brush for effectively dislodging and disposing of dirt and lint particles from garments and other surfaces. Furthermore, to achieve improved cleaning effectiveness it would kbe desirable to have a substantially self-cleaning brush so that dirt or lint particles which tend to adhere to the brush would be eliminated therefrom. It would also be desirable to be able to clean entangled threads from the brush while the brush is mounted within the cleaner, or to be able to easily withdraw the brush for cleaning or replacing the same. An additional improvement would be to substantially neutralize the static electric charge on the rotating brush produced by the brush contact with a surface.
It is therefore one object of this invention to provide an improved, more compact cleaner for effectively removing dirt and lint particles from surfaces.
Another object is to provide clothes cleaning apparatus which employs a unique structure for establishing an air flow pattern for effectively sweeping up and depositing lightweight dirt and lint particles into a collection-chamber.
A further object is to provide a clothes cleaning apparatus having a brush which is easily cleaned while mounted within the apparatus, or easily withdrawn for cleaning or for inserting a replacement.
Still Ianot-her object is to provide a clothes cleaning apparatus which neutralizes the effect of static charge produced by brushing contact with garments.
In accordance with this invention in one form thereof, a palm size molded plastic housing is structurally designed -to receive a rotating brush which projects outwardly through a nozzle in one wall of the housing. Air ingestion means and a `discharge gap are disposed relative to the rotating brush and the nozzle to achieve a pumping or vacuum effect which assists the -brush in sweeping up lightweight dirt and lint particles and disposing of these particles which are normally unaffected by conventional centrifugal discharge apparatus. The housing is also structurally arranged to define a collection-chamber adjacent the discharge orifice into which the dirt and lint particles are deposited, and a series of filtered outlet passages throug-h the housing are provided to enable a continuous air flow through the clothes cleaner.
The invention encompasses the features of a clothes cleaner housing in combination with the compact Iarrangement of internal components which will be more fully understood by reference to the following detailed description taken in connection with the accompanying drawings, of which:
FIG. l is a perspective view of the compact clothes brush when manually grasped during operation thereof;
FIG. 2 is an elevation view in section showing the components and their Iarrangement within the compact clothes brush;
FIG. 3 is a vertical section view along the lines 3 3 Iof the elevation view of FIG. 2;
FIG. 4 is a perspective view in section illustrating the air flo-w pattern through the clothes cleaner as induced by the unique construction thereof;
FIG. 5 is van enlarged elevation view in section of the brush retainer member which is releasably secured to the housing for permitting manual rotation or withdrawal of the brush;
FIG. 6 is a left end view of the battery-powered clothes bmsh with the Ibrush retainer member removed.
Referring to FIG. l, the compact clothes cleaner is illustrated being manually held by the housing 1 during normal operation. It can readily be appreciated that the relative compactness and the self-powered aspect facilitates convenient use of the clothes cleaner under a wide range of conditions.
The arrangement of the components which permits such a compact cleaner are more clearly indicated in the remaining figures. The housing 1 is composed of a housing base-portion 1a and a housing cover-portion 1b, between which the cleaner components are secured. FIG. 2 illustrates the components as they are mounted on the housing base-portion 1a with the housing cover-portion 1b removed. A cylindrical brush 2 is disposed within the housing 1 along the top wall WT thereof. The brush consists of a plurality of bristles b secured between a pair of helically twisted wires w1.
The left end of the brush 2 is releasably supported in a brush retainer member 3 which is, in turn, releasably attached in an aperture Ab through the left wall WL of Vthe housing 1. As indicated in FIG. 5, the retainer member 3 is comprised of a hollow retainer casing 3a which has spherical bearing pocket 3d within the hollow central portion thereof. The bearing pocket 3d supports a spherical journal portion of a rotator member 3c. The rotator member 3c has an outwardly directed face plate Fp which can be manually turned for rotating the brush 2. One end of the brush wires w1 and W2 are releasably secured within the opposite end of the rotator member 3c, c which has a firs-t thread guard g1 positioned thereon for preventing threads or thread particles from entering the bearing pocket 3d. A pair of studs 3e are positioned on vthe outer peripheral surface of the retainer casing 3a and project through the recess r1 and r2, as indicated in FIG. 6, on ythe peripheral edge of the housing aperture Ab for engaging the inner surface of the housing left wall WL when the retainer is twisted after being inserted into the aperture Ab. The engagement between the studs 3e and the inner surface of the housing left wall WL operates to secure the retainer 3 within the housing 1. The right end of the crush 2 is releasably supported in and secured for rotation with a brush drive shaft `4. A second thread guard g2 is fixed to the left end of the drive shaft 4 to prevent thread or dust particles from passing into the compartment S which is separated from the brush 2 by a first vertical partition member 6 on each of the housing-portions 1a and 1b.
A face gear member 7 is secured to the drive shaft 4 near the right end thereof, and is positioned for meshed engagement with -a pinion 8. The pinion 8 is fixedly secured on the rotating shaft of an electric motor 9 which is, in turn, positioned adjacent the right end wall of the housing 1 and is retained by a rubber spacer member S. A casing extension 9a from the motor 9 supports the right end of the drive shaft -4 and thereby maintains the face gear 7 and the pinion 8 in continuous meshed engagement.
A rechargeable battery B is disposed within the housing 1 adjacent the bottom wall WB there-of. The battery B is also secured between the housing-portions 1a and 1b, and is electrically lconnected to a pair of contact members 10 and 11 which extend outwardly through the housing wall to contact recharging apparatus (not shown). A switching element 12 is disposed on a stud member 13 projecting from the housing base portion 1a and positioned along the left end wall WL of the housing 1. A switch button 14 extends through the left end wall WL of the housing, and a cam member 15 attached 'to the switch button 14 operates to engage and disengage the switch element 12 with the battery B. Electrical conductors C1 and CZ complete the circuit between the battery B and the motor 9 upon engagement and disengagement of the switch element 12 for operating the motor 9 and, consequently, for rotating the brush 2.
A collection-chamber 16 is centrally disposed iwi-thin the housing 1. As illustrated in FIG. 3, the chamber 16 is defined on the lower side by the brush 2 and a brush enclosure member 17 formed integrally with the inner surface of the housing cover-portion 1b. The chamber 16 is defined on the right end by the first vertical partition member `6, on the lower side by a horizontal partition member 1'8, on the left end by a second vertical partition member 19, and on the front and rear sides by the inner surfaces of the housing coverand base-portions 1b and 1a, respectively. The first and second vertical partition members 6 and 19, and the horizontal partition member 18 are formed by complementary shelf structures on the housing baseand cover-portions, 1a and 1b.
The physical relationship between the brush 2 and the collection-chamber 16 can be clearly appreciated by reference to FIGS. 3 and 4. When the housing base-portion 1a and the housing cover-portion 1b are joined to form the over-all housing 1, the brush 2 is substantially enclosed by the interior surfaces of the housing portions, 1a and 1b, and by the brush enclosure extension 17 formed integrally with the inner surface of the housing coverportion 1b and which conforms to `a portion of the peripheral surface of the brush 2. A pair of recessed edge portions 20 and 21 along the top edge of the housing baseand cover-por-tions, 1a and 1b, respectively, define a rectangular nozzle N through which the peripheral surface of the brush 2 projects.
A scroll member 22 is attached to the interior surface of the housing base-portion 1a to form a smooth curvilinear surface which defines a discharge slot or gap G with the -tip of the brush enclosure extension 17. The gap G is substantially tangentially oriented to the rotating brush 2 so that air carried along with the brush is impelled outwardly through the -tangentially oriented discharge gap G.
Referring to FIGS. 3 and 4 which illustrate the clothes cleaner with the housing portions 1a and 1b assembled, the housing cover-portion 1b has a clean-out door 23 releasably hinged and latched thereto for providing ready access to lthe collection-chamber 16 for disposing of the accumulated particles. A plurality of air exhaust slots 24 are provided through the clean-out door 23 and a first filtering membrane 25 on the inner surface of the door 23 covers the door slots 24 to preclude discharge of particles out through the door slots to prevent their redisposition on the garment. A second plurality of slots 26 are disposed through the housing base-portion 1b above the horizontal partition member 18 and below the scroll member 22 through which air may be exhausted from the collection-chamber 16. A second filtering membrane 27 on the inner surface of the housing base-portion 1a covers the base-portion slots 26 for excluding discharge of dirt particles therethrough.
The brush 2, when rotating counterclockwise as indicated in FIGS. 3 and 4, establishes a rotating air flow pattern which is exhausted through the tangentially oriented discharge gap G. A suction force is created at the nozzle N by virtue of the Bernoulli-effec-t produced by liuid flowing thereby. The suction tends to draw the garment into the nozzle, thus cutting off the air fiow around the brush 2. The lightweight dirt and lint particles are not thereafter carried through the discharge gap G, but remain on the rotating brush to be deposited back on the garment and to carry with them the accumulated static electric charge.
To provide a continuous supply of air for sweeping past the nozzle to aid in extracting particles from a garment, a first plurality of air inlet apertures 28 are provided lthrough a first canted surface portion S1 on the top wall WT of the housing 1 adjacent the nozzle side 21 where the brush periphery leaves the housing. The canted orientation of the surface S1 relative to the nozzle N insures that the garment will not cover the first inlet apertures 28. The inlet apertures 28 have their axes a1 oriented radially inwardly to also insure that the air is not impelled outwardly therethrough. If desired, a similarly oriented slot may be used instead of a plurality of apertures.
To provide an additional supply of air for sweeping the dirt and lint particles from the brush 2 to effect selfcleaning, a second plurality of air inlet apertures 29 are provided through a second canted surface portion S2 on the top wall WT adjacent the nozzle side 20 where the brush periphery re-enters the housing. The canted orientation of the surface S2 similarly insures that ythe garment will not cover the second inlet apertures 29, and the axes a2 of the apertures 29 are also radially oriented relative to the brush 2.
The unique structure comprising the air inlet apertures 28 and 29 adjacent the nozzle N, the tangentially oriented discharge gap G between the brush enclosure extension 17 and the scroll 22, the accessible collection-chamber 16, the filtering membranes 25 and 27, and the discharge slots 24 and 26 capitalizes on the rotary motion of the brush to provide a continuous filtered fiow of air through the cleaner. The air flow continues through the air inlet apertures 28 and 29 even while the nozzle N is completely covered by the garment being cleaned. It can also be appreciated that the bristle sweeping action yagainst the cloth in combination with air iiow induced through the rst inlet apertures 28 by the rotating brush operates to pick up dirt and lint particles from the garment, and the additional air flow induced through the second inlet apertures 29 `provides a greater air mass for separating from the brush the dirt and lint particles of small mass which are normally retained in the brush and are deposited back on the garment where they build up a static electric charge at the nozzle. The static electric charge is `also reduced by the apertures 28 and 29 which reduces the amount of possible surface contact between the garment and the cleaner. The structural feature of the retainer 3 and the manual rotator face plate FP en-able manual rotation of the brush '2 to enable removal of threads that have become entangled between the bristles. The removable feature of the retainer also enables easy removal of the brush for more thorough cleaning or for replacing the bnush without disassembling the housing 1.
By employing the unique stnucture of this invention, the brush is self-cleaned, static electric change is reduced, and a vacuum-effect is achieved without having to ernploy a separate pumping' member, thereby providing a more compact, effective clothes cleaner which is easily handled and stored.
As is evident from the foregoing description, certain aspects of my invention are not limited to the particular construction details of the example illustrated, and I contemplate that various and other modifications and applications will ocour to those skilled in the art and to those who employ my invention. It is therefore my intention that the appended claims shall encompass such modifications and applications which do not depart from the true spirit and scope of my invention.
