Description
? . ~L1!B~34~3L7 .
The present invention relates to a brush, and more particularly, to a seIf-cleaning brush in which the bristles of the brush can be retracted within apertures formed through the anterior wall of the brush to remove foreign materials such as hair, debris, etc., and the bristles can be readily held in place when the brush is in use for normal brushing ; purposes.
A brush, for examplej a hair brush, tends to pick up foreign materials such as hair, deb ris, etc. which h ave to 10 be removed from the brush bristles periodically by means of suitable means such as, for example, another brush, or ~a comb.
It is rather time-consuming and is often inconvenient to remove such foreign materials in such conventional manner.
There have been proposed a number oE so-called self-, cleaning brushes which are equipped with means to remove such ^ foreign materials from bristles, and these have been employed to some extent. For example, U. S. Patent 2,529,927 issued November 14, 1950 to H.W. Fis}~ and U.S. Patent 2,916,757 ~; issued December 15, 1959 to L.R. Peilet et al disclose a <
20 mobile cleaning plate whose relative movement to the brushbody is limited. The cleaning plates are lifted by fingers while retaining their respective brush bodles. U. S. Patent

2,916,756 issued December 15, 1959 to L.R. Peilet et al discloses a double acting self-cleaning retractable brush.
~- Referring to Figures 1 and 2 of that paten-t, for cleaning purposes, the upper housing mernber 18 is turned in one "A'; direction. By this action, the bristle carrying member 22 descends within the lower housing member 20 while rotating with the upper housing member 18, thus allowing a compact 30 structure.
U. S. Patent 2,660,183 issued November 24, 1953 ~o A.Gruring alsa discloses a self-cleaning brush. The bristles ,'' ~
, . . .
~`
supporting plate 30 and comb supporting plate 32 are raised or lowered by means of the respective control screws 20 and 22. The cover plate 50, which defines a plurali~ty of apertures therethrough, is integral with the handle body or casing 10 and therefore is stationary. m e bristles 40 and combs 42 can be retracted within the handle body or casing 10, The self-cleanin~ brushes disclosed in U. S. Patents ` 2,916,756 and 2,916,757 do not contain any locking mechanism which is adapted to retain the bristles in place when the brushes are in use for normal brushing purposes. Accordingly, the cleaning plates may move during the course of the use of the self-cleaning brushes, thus hampering the brushing application.
The self-cleaning brush according to the invention disclosed in U. S. Patent 2,529,927 includes a locking mechanism which normally retains the cleaning plate in a locked position. m e cleaning plate is, however, mobile; and the bristles are normally exposed. In order to clean the bristles, the hooks 13 have to be first released from their locked position one by one. This is rather slow and cumber-some.
According to the drawings of U. S. Patent 2,660,183, and particularly Figures 3 to 6, a bristle or comb supporting plate is attached to the free end of its respective screw.
A firm attachment would cause the supporting plate to move - with difficulty, and a loose attachment would render it unstable and susceptible of breakage.
Another example of a self-cleaning brush is disclosed in U. S. Patent 3,110,053, issued November 12, 1963, to E.C. Surabian. Surabian provides a foraminous cleaning plate (18) through which the bristles (12~ of the brush pass.
This plate is normally heId against the under surface on the back of the brush by spring members (26,28). Plate (13~ has a central post (22) projecting upwardly through an aperture in the back of the brush, and one end of each of the springs is fitted into a notch on the upper end of the post (22). By pushing down on the springs the plate (20) with the post (22j is pushed outwardly toward the ends of the tufts of bristles, permitting cIeaning of the brush, and when the pressure on h ; the springs is released they revert to their normal arcuate positions, thus causing retraction of the foraminous cleaning plate. Since the cIeaning plate (20) is mobile, the bristles L
are exposed; due to the use of spring members, the manufactur-ing cost would be rather high and it would be susceptible of breakage.
. -;~ An objectlve of the present invention is to provide a ~' self-cleaning brush which is of slmple and inexpensive ;~ construction, and which operates ea~ily and effectivaly.
- A further, more specific objective of this invention is to provide a self-cleaning brush in which the bristles thereof may be readily drawn into and out of the main body ;~ - of the brush in order that foreign materials such as hair, debris, etc., can be easily removed from the fac-e of the v bru5h; and having locking means operable so that when the bristles are in their extended or operating position, they can be locked into this position ready for use.
~; The present invention, in its broadest aspect, resides in a self-cleaning brush comprising a brush body member comprising a posterior wall having a first opening therethrough, an anterior wall member having therein a plurality of spaced apertures, and a side wall integrally ~.
, .
joined with the posterior and anterior walls, said walls defining a hollow compartment in the interior of the body member, said first opening in said posterior wall communicat-ing with said hollow interior compartment; a reciprocably movable bristle supporting member generally disposed within the hollow compartment and comprising a brush head from whoS3 lower sur~ace a plurality of bristles extend in registration with the apertures in said anterior wall member ;
and a brush head operating member lntegral with the upper o surface of the brush head, and extending in a Dlane p~rpendicular to the axis of the brush body member through said first opening in the posterior wall, and projecting above said posterior wall; said brush head operating member being adapted to move reciprocably within the hollow compart-ment from a first fully exten~ed position in which the brush head is in juxtaposition with said anterior wall member and said bristles project through their respective apertures in said anterior wall member, to substantially their full length, at which position the brush is operable as such~ ~o a second retracted position in which the brush head is in juxtaposition with the inner surface of the posterior wall of said brush body member, at which position the brictles are fully retracted within the body, the tips of said bristles being within the apertures in said anterior wall member, thereby to allow the eas~ removal of hair or debris from said bristles.
~ lore particularly the:present invention provides a self-cleaning brush as described in the immediately preceding paragraph, which further includes a locking mechanism adapted to lock the bristle supDorting means when the brush is in use for brushing. The locking mechanism comprises a lever memker which extends from the f, ~ 4-exterior of the brush bod~ adjacent the side wall through a second opening formed in the ~rush body, in a plane normal to the longitudinal axis of said brush body, and at least one recess formed in the bristle supporting member and adapted to receive at least the inner end portion of the lever member, said lever member being reciprocably movable into and out of engagement with said recess in said .. . . . . ................................. .. . .... .. . . . . .

m e advantag~ derived fro~ the present invention are numerous. For example, the bristle supporting means is mobile and therefore the bristles can be retained within the brush body to protect the bristles, when it is not in use, particularly when it is carried in a bag. Where the self-cleaning brush according to this invention is not equipped with a locking mechanism, a user must hold the bristle sup-porting means in place at the free end of the brush head operating member. This is not necessary where the self-cleaning brush is provided with such a locking mechanism as described above. Either way, the brush head is held in place when the brush is applied, and the brush operation will not be hampered. The construction of the self-cleaning brush of the present invention is rather simple, and thus the b ~ h is simple to use, inexpensive to manufacture and less susceptible to breakage.
Other features and advantages of the present invention will become more apparent from the following detailed des-cription of a preferred embodiment of this invention, with reference to the appended drawings, in which:

Referring now to the drawings, the brush body 1, which may be constructed of any suitable material such as wood, "
metal or plastic, is in the form of a shell; and comprises a posterior wall 2, an anterior wall member or plate 3, and ~ ;.
a side wall 4 extending between the peripheries of the posterior wall 2 and anterior plate 3, the side wall being integral with said posterior wall, and also being integrally connected to the anterior plate 3. The posterior and side walls, and anterior wall p~late 3, define a central cavity 18.
The brush body 1 is also provided with a handle 5 for convenience; this may be, if present, an integral part of the brush body. The handle 5 is, however, optional and may be omitted if desired. A first opening 6 communicating with central cavity ., ? ~ 3 9~
18 is centrally located in the posterior wall 2, and the anterior plate 3 has therein a plurality of spaced apertures 7 (See Fig. 6). The posterior wall 2 also has a second opening 8 extending perpendicularly to the longitudinal axis of the brush body 1 and communicating with the first opening 6.
The side wall 4 has, at a location where it is integrally connected with the posterior wall 2, an aperture 23 which is , -in communication with said second opening 8 in the posterior " wall.
~ he main body 1 houses a reciprocably movable bristle supporting means whlch coDsists of a brush head 11 and a brush head operating member 12 which is integral with the .:
'~ ~ brush hea~ 11 and extends from the upper surface of the ,' brush head 11 in a plane perpendicular to the axes of brush body 1 and of bristle head 11, through opening 6, and projects ~ slightly above posterior wall 2. The brush head ll supports '; a plurality of bristles 13 which are rigidly affixed to said ;: ~
- brush head 11 and extend ~rom the lower surface thereof in a pattern in registration with the plurality of apertures 7 formed through the anterior wall 3. The brush head operating ., member 12 is provided wlth a grasping knob 14 at the opposite end thereof to the bristle head 11 (its free or proximal end).
Grasping knob 14 is located outside posterior wall 2 of the brush, and is firmly af~ixed to the proximal end of member 12. The bristle head operating member 12 and bristle head 11 to which it is connected are both somewhat plate-like in form.
A plurality of recesses 15 are formed in spaced-apart relationship in the brush head operating member 12, which recesses 15 are adapted to engage the distal end portion , which may be designated as a locking panel 19, of a lever member 16, which extends through the aperture 23 in the side wall 4 at a location where said side wall is integrally ., .
.: t a~
joined with posterior wall 2, and thence through the secondopening 8 in said posterior wall.
Lever member 16 comprises at one end ~its distal end) a plate-like member, denoted here as a locking panel 19, rectangular in outline, which is integrally connected to a stem portion 20 which projects therefrom perpendicularly to the longitudinal axis of said locking panel 19 (and in a plane normal to the longitudinal axis of brush body 1), and ~"y ~ extends through opening 8 and aperture 23 to the exterior ;~ - .
`~ of body 1, adjacent the juncture of side wall 4 with . ~ posterior wall 2. To the proximal end of stem portion 20,,":
of lever member 16 is attached a grasping member or knob 21, which enables lev.~r member 16 to be moved readily into and i ; ~ out of locking engagement with the brush head operating member 12, as desired.
To illustrate the way in which our self-cleaning brush ~ may be used for brushing, reference is made to Figs. 2, 3 s and 7 of the drawings.
The brush head operating member 12 is pushed down until the bristles protrude to a desired length beyond anterior plate 3 of the brush, as shown clearly in Figs. 2 ~ and 7. When the bristles extend through the apertures to ~ their full length, as is illustrated in Figs. 2 and 7, brush Y head 11 will be in juxtaposition with anterior plate 3.
~ Then the lever member 16 is pushed inwardly (see Fig~ 3) 50 -;i that locking panel 19 extends into recess 15 (and desirably completely through said recess 15, the recess being an aperture in member 12). In this position, the lever member 16 serves as a locking means, and prevents upward movement of the operating member 12 and bristles 13. The length of bristles protruding from the brush can be adjusted by making ;' ~ -7-, "
."
3~7 an appropriate selection of recess or aperture 15 into which the lever member 16 is to be pushed into locking engagement.
The brush is also operable without the recesses 15 and the lever member 16. In this case, a user must hold the grasping knob 14 beneath the palm of his (her) hand while his (her) fingers hold the side wall 4 of the brush body 1. Otherwise the bristles 13 would tend to move inwardly, thereby hamper-ing operation of the brush. It is preferred to form several recesses 15 in the brush head operating member 12 in order to allow for adjustment of the length of the bristle 13 protruding from the anterior wall 33, as desired, depending on such factors as, for instance, the length of hair to be brushed. The apertures 7 are of a diameter sufficient to .~
permit easy passage therethrough of brlstles 13, and thereby prevent the same from being bent, but not being~large enough to allow the passage of hair or other debris clinging to the bristles after brushing is completed, into the interior cavity 18 of the brush.
After use of our device for brus~ing, the brush may be cleaned in the following manner, making reference here to Figs. 4 and 5 of the drawings. ~fter brushing, the bristles 13 of the brush normally carry a quantity of hair, To remove the hair from the bristles, the lever member 16 is first released from locking engagement with one of the .
recesses 15. By pulling outwardly on grasping knob 21;
- this causes the locking panel 19 of lever member 16 to , ,~, slide out of engagement with recess 15. Then, the bristle supporting means is pulled in a direction awav from the anterior plate 3 by means of grasping knob 14 until the free ends of the bristles 13 are retracted within their respective apertures 7. When the bristles are fully ~ .
retracted, the brush head 11 will be in juxtaposition with the inner surface of posterior wall 2. The retraction of the bristles 13 within the brush body causes the hair to disengage from said bristles, since apertures 7 are large enough to permit only the passage of the bristles there-through. Thus the hair is left behind on the outer surface of the anterior plate 3, ready to discard. Thus the ' anterior plate 3, viz. the front face of the brush, can be cleaned readily without having the bristles interfere with the cleaning act~
The recesses 15 preferably take the form of apertures in operating member 12, the apertures being dimensioned such that they wlll slidably receive locking panel l9 of lever member 16. m e second opening 8 may be further extended into the opposlte slde of the posterior wall 2, to form a recess 22 therein on the side of said first opening therein, opposite to that which is adjacen~ opening 8, thereby to allow the lever member 16 to extend through a substantial len~:th of'~he posterior''wall 2, and into recess 15 in the form of a hole in the brush head operating member 12; this , ~ provides added security in locking the bristles in place .
when the brush is in operative position.
The second opening 8 may be formed through the side wall 4 but is advantageously formed through the posterior - wall 2 for better support, as indicated above.
The lever member 16 and the bristle supporting member ' 11, with associated knobs 21 and 14 respectively, may be ~'^ constructed of any suitable material, 6f the same class of materials from which body member 1 o~ the brush is constructed.
Preferably, the lever member and the bristle supporting member will be made of the same material as that from which "
. , . ~ , body member 1 is constructed.
;Although the present invention has been described with reference to a preferred embodiment, it will be appreciated that various modifications are feasible without departing from the spirit of this invention. -~t is intended, . then, that this invention be limited only by the claims ~-which follow.

'~ ~ brush hea~ 11 and extends from the upper surface of the ,' brush head 11 in a plane perpendicular to the axes of brush body 1 and of bristle head 11, through opening 6, and projects ~ slightly above posterior wall 2. The brush head ll supports '; a plurality of bristles 13 which are rigidly affixed to said ;: ~
- brush head 11 and extend ~rom the lower surface thereof in a pattern in registration with the plurality of apertures 7 formed through the anterior wall 3. The brush head operating ., member 12 is provided wlth a grasping knob 14 at the opposite end thereof to the bristle head 11 (its free or proximal end).
Grasping knob 14 is located outside posterior wall 2 of the brush, and is firmly af~ixed to the proximal end of member 12. The bristle head operating member 12 and bristle head 11 to which it is connected are both somewhat plate-like in form.
A plurality of recesses 15 are formed in spaced-apart relationship in the brush head operating member 12, which recesses 15 are adapted to engage the distal end portion , which may be designated as a locking panel 19, of a lever member 16, which extends through the aperture 23 in the side wall 4 at a location where said side wall is integrally ., .
.: t a~
joined with posterior wall 2, and thence through the secondopening 8 in said posterior wall.
Lever member 16 comprises at one end ~its distal end) a plate-like member, denoted here as a locking panel 19, rectangular in outline, which is integrally connected to a stem portion 20 which projects therefrom perpendicularly to the longitudinal axis of said locking panel 19 (and in a plane normal to the longitudinal axis of brush body 1), and ~"y ~ extends through opening 8 and aperture 23 to the exterior ;~ - .
`~ of body 1, adjacent the juncture of side wall 4 with . ~ posterior wall 2. To the proximal end of stem portion 20,,":
of lever member 16 is attached a grasping member or knob 21, which enables lev.~r member 16 to be moved readily into and i ; ~ out of locking engagement with the brush head operating member 12, as desired.
To illustrate the way in which our self-cleaning brush ~ may be used for brushing, reference is made to Figs. 2, 3 s and 7 of the drawings.
The brush head operating member 12 is pushed down until the bristles protrude to a desired length beyond anterior plate 3 of the brush, as shown clearly in Figs. 2 ~ and 7. When the bristles extend through the apertures to ~ their full length, as is illustrated in Figs. 2 and 7, brush Y head 11 will be in juxtaposition with anterior plate 3.
~ Then the lever member 16 is pushed inwardly (see Fig~ 3) 50 -;i that locking panel 19 extends into recess 15 (and desirably completely through said recess 15, the recess being an aperture in member 12). In this position, the lever member 16 serves as a locking means, and prevents upward movement of the operating member 12 and bristles 13. The length of bristles protruding from the brush can be adjusted by making ;' ~ -7-, "
."
3~7 an appropriate selection of recess or aperture 15 into which the lever member 16 is to be pushed into locking engagement.
The brush is also operable without the recesses 15 and the lever member 16. In this case, a user must hold the grasping knob 14 beneath the palm of his (her) hand while his (her) fingers hold the side wall 4 of the brush body 1. Otherwise the bristles 13 would tend to move inwardly, thereby hamper-ing operation of the brush. It is preferred to form several recesses 15 in the brush head operating member 12 in order to allow for adjustment of the length of the bristle 13 protruding from the anterior wall 33, as desired, depending on such factors as, for instance, the length of hair to be brushed. The apertures 7 are of a diameter sufficient to .~
permit easy passage therethrough of brlstles 13, and thereby prevent the same from being bent, but not being~large enough to allow the passage of hair or other debris clinging to the bristles after brushing is completed, into the interior cavity 18 of the brush.
After use of our device for brus~ing, the brush may be cleaned in the following manner, making reference here to Figs. 4 and 5 of the drawings. ~fter brushing, the bristles 13 of the brush normally carry a quantity of hair, To remove the hair from the bristles, the lever member 16 is first released from locking engagement with one of the .
recesses 15. By pulling outwardly on grasping knob 21;
- this causes the locking panel 19 of lever member 16 to , ,~, slide out of engagement with recess 15. Then, the bristle supporting means is pulled in a direction awav from the anterior plate 3 by means of grasping knob 14 until the free ends of the bristles 13 are retracted within their respective apertures 7. When the bristles are fully ~ .
retracted, the brush head 11 will be in juxtaposition with the inner surface of posterior wall 2. The retraction of the bristles 13 within the brush body causes the hair to disengage from said bristles, since apertures 7 are large enough to permit only the passage of the bristles there-through. Thus the hair is left behind on the outer surface of the anterior plate 3, ready to discard. Thus the ' anterior plate 3, viz. the front face of the brush, can be cleaned readily without having the bristles interfere with the cleaning act~
The recesses 15 preferably take the form of apertures in operating member 12, the apertures being dimensioned such that they wlll slidably receive locking panel l9 of lever member 16. m e second opening 8 may be further extended into the opposlte slde of the posterior wall 2, to form a recess 22 therein on the side of said first opening therein, opposite to that which is adjacen~ opening 8, thereby to allow the lever member 16 to extend through a substantial len~:th of'~he posterior''wall 2, and into recess 15 in the form of a hole in the brush head operating member 12; this , ~ provides added security in locking the bristles in place .
when the brush is in operative position.
The second opening 8 may be formed through the side wall 4 but is advantageously formed through the posterior - wall 2 for better support, as indicated above.
The lever member 16 and the bristle supporting member ' 11, with associated knobs 21 and 14 respectively, may be ~'^ constructed of any suitable material, 6f the same class of materials from which body member 1 o~ the brush is constructed.
Preferably, the lever member and the bristle supporting member will be made of the same material as that from which "
. , . ~ , body member 1 is constructed.
;Although the present invention has been described with reference to a preferred embodiment, it will be appreciated that various modifications are feasible without departing from the spirit of this invention. -~t is intended, . then, that this invention be limited only by the claims ~-which follow.
