Another purpose of this invention is to recycle, salvage, and convert the discarded heaps of suitable sheet material such as sheet metal scrap into useful paint brush wipers. All of our disposal techniques are under strong criticism. Across the land, there is increasing support for resource recovery, and for combating solid waste pollution. Because the present invention can be made from only a very small portion of sheet metal, it lends itself remarkably well to fabrication from the waste fragments of the sheet metal converting industry.
An object of this invention is the provision of a paint brush wiper that is practical, inexpensive, efficient, economical, easy to install and easy to install and remove from a paint can.
Another object is to provide a paint brush wiper all the parts of which are initially flat and coplanar, for ease of stacking, packaging, and shipping, and which is subsequently easily bent to adapt and accommodate it to use on a paint can.
Still another object of this invention is the provision of a brush wiper all the parts of which are flat and coplanar, for detachable affixation flatwise on the top surface of a cover for a paint can for convenience of shipment, distribution, display, and convenience of the customer.
Yet another object of this invention is to provide a paint brush wiper which can be readily adapted to paint cans of various sizes, by the enlargement or reduction in overall size of such brush wiper.
A further object is the provision of a paint brush wiper which can be readily adapted to paint cans of various sizes by bendably accommodating pertinent members of the wiper to the paint can dimensions.
Other specific features and many of the attendant advantages of this invention will be readily appreciated as the same becomes better understood by reference to the following detailed description when considered in connection with the accompanying drawings in which like reference numerals designate like parts throughout the figures thereof and wherein:
FIG. 1 is a plan view of the planar brush wiper invention;
FIG. 2 is a rear elevation view of the ,device shown in FIG. 1, showing the interlockable arms thereof bent operatively downwardly as indicated by'dotted lines;
FIG. 3 is a plan view showing the device of FIG. 2 operatively and interlockably secured to the open top portion of a paint can;
FIG. 4 is a section view taken on line 44 of FIG. 3, showing in detail the interlocking relation of the brush wiper device with the rim and body portion of paint can;
FIG. 5 is a fragmentary plan view of a paint can and a removable cover therefor, and showing an afiixation tab on the blade of the wiper detachably securing the wiper flatwise on and to the top planar surface of the cover, as by soldering and the like;
FIG. 6 is a side elevation view of the apparatus of FIG. 5, showing by dotted lines the means of disjoining and separating the wiper from the affixation tab as by alternate reverse bending at their line of juncture; and
FIG. 7 is a fragmentary plan view of a modification showing the biceps portion of the interlocking arm abuttable with the outer surface of the inner side wall of the trough, such as with the bead or lip thereof.
Referring now to the drawings, wherein like reference numerals designate like or corresponding parts throughout the several views, there is generally indicated at 10 a conventional paint container comprising a paint can 11 and a cover 12 therefor, see FIG. 5.
Said conventional paint can 11 has a cylindrical body, a bottom, and is open at the top, see FIG. 3. The top end portion of said can body is provided with a conventional inwardly projecting circular rim means generally indicated at 13, see FIG. 4.
The intumed rim 13 is secured on and along the top edge of the body portion of said can by reverse crimping and clamping a longitudinal edge portion of said rim over said top edge, in inverted U-shape fashion, thereby forming a vertical circular bead or flange 14 around the top edge of said can body.
Projecting inwardly from the inner lower portion of said can flange 14 is an annular horizontal berme or shoulder 15 from the inner edge of which depends an annular trough generally indicated at 16.
Said annular trough 16 comprises an outer side wall 17 integrally connected to the inner edge of shoulder 15, a bottom 18, and an inner side wall 19 terminating in a reverse crimped beaded annular lip 21.
The top of bead 21 is disposed slightly below the level of the top of can flange 14.
Cover 12 is provided with a rim flange 22 and a pressed down annular groove 22' press-fit and snugly receivable in trough l6, and the under surface of said cover is engageable with said trough bead 21 when the cover is operatively disposed as a closure on can 1 1, see FIGS. 4 and 5.
The above conventional can 11 and conventional cover 12 combine to make up a conventional paint container 10 which provides the setting for the new and novel paint brush wiper to which said wiper is adapted and operatively applied, as hereinafter described.
The paint brush wiper generally indicated at 23, see FIG. 1, is fabricated or punched from a flat sheet metal member, 28 gauge thickness having been found suitable, and sufficiently stiff; however the invention is not limited to such thickness. Obviously the wiper device can be made of other material suitable for the intended purpose.
Conventional galvanized steel sheet metal has been found suitable as a material for making the brush wiper in that it is suitably flexible, that is, it is easily bent and deformed and adapts itself readily to change of shape as hereinafter described.
In the event a die is made shaped to conform to the configuration of the brush wiper, the wipers can be punched out from such sheet metal on a punching machine. However, fabrication of the wiper can be accomplished by generally acceptable procedures, depending on the material used. I
The wiper comprises an elongated flat strip or blade member 24 having front and rear. longitudinal edges, respectively, and having an open generally U-shaped flat body portion generally indicated at 25 extending rearwardly therefrom, and the ends of the legs 26 and 27 of said U-shaped body being integrally connected to the rear edge of said blade at points equally spaced from the ends of said blade, respectively. That is, the flat U-shaped body is disposed symmetrically about the transverse axis of said blade and is coplanar with the blade. Said blade is adapted to span the open top of said paint can and seat on the rim thereof. The legs 27 and 26 are also adapted to seat on the rim.
The curvilinear cross member, of the U-shaped body 25, generally indicated at 28 is provided with an inwardly extending flat tongue 29 and an oppositely disposed and outwardly extending flat finger tab 31, both projecting centrally from said cross member 28. Said tongue and finger tab are coplanar with the flat U- shaped body 25.
A pair of oppositely disposed similar angular or curved arms generally indicated at 32 and 33 extend inwardly from the inner edge portions of legs 26 and 27, respectively. Said arms are flat and preferably right angular in configuration comprising inwardly projecting biceps portions 34 and 35 extending laterally from legs 26 and 27, respectively, and rearwardly extending forearm portions 36 and 37 projecting substantially at right angles from the ends of said biceps portions 34 and 35, respectively. Said flat arms are coplanar with said flat blade 24 and with said flat U-shaped body 25.
In operation said arms 32 and 33 are bent downwardly substantially 90 degrees, see FIGS. 2, 3 and 4, to positions generally indicated at 32 and 33', with the biceps portions being now disposed in positions 34 and 35 and the forearm portions in positions 36' and 37, respectively.
With such bent condition of the arms, the end portions of the flat blade 24 and the end portions of legs 26 and 27 are seated on the rim 13 such as on the flange 14 or bead 21 thereof, the blade 24 being disposed in spanning relation to the open top of the can, and the right angular arms 32 and 33 are then slid under the annular trough 16, with the forearm portions disposed adjacent the under side or under surface of the bottom of the trough as at 38, see FIG. 4, and the ends of said forearms disposed adjacent an inner surface of said can, such as adjacent the inner surface or inner periphery of the cylindrical body side wall of said can as at 39, see FIG. 3.
The tongue 29 is then pressed and bent downwardly into trough 16 with the end of said tongue being disposed adjacent the inner surface of the inner sidewall 19 of said trough, as at 41, see FIG. 4, and engageable therewith.
The sheet metal material being flexible, as defined above, is quite easily bent and the arms and tongue above mentioned will hold the shape and position to which they were bent.
To remove the wiper from the can, one merely presses downwardly on finger tab 31 thereby raising the tongue end from the trough and its adjacence to side wall 19, and the wiper can then be retracted forwardly thereby removing the forearm from under the trough, and then lifting the wiper bodily from the rim of the can.
As above described and applied to the open top of the can, the wiper is secured against accidental downward displacement by the blade 24 being seated on the rim 14 of the can, against significant upward displacement by the forearms 36 and 37 engaging the bottom 18 of trough 16, against significant sidewise and rearward displacement by the forearm ends engaging with the cylindrical wall of the can, and against significant forward displacement by the engagement of the end of tongue 29 with the opposite side-wall 19 of trough l6.
To accommodate the wiper arms to the cylindrical wall of smaller diameter cans, the arms can be bent downward less than such as 45, as generally indicated at 42, by dotted lines, see FIG. 2, to a disposition adjacent such smaller diameter inner periphery.
To accommodate the wiper arms to the cylindrical wall of a larger diameter cans the arms can be bent downward and outwardly such as such as generally indicated at 43, by dotted lines, see FIG. 2, to a disposition adjacent such larger diameter inner periphery.
Obviously, the initial basic design of the wiper can be made in different sizes to accommodate the wiper to such corresponding cans, thereby negating the necessity of adapting the angular disposition of the arms to the particular can, as described above.
The above lesser and greater degree of bent disposition can also be used to accommodate the wiper arms to can troughs of shallower depth, if desired.
The wiper can thus be readily adapted to paint cans of various sizes.
In lieu of the cooperative adjacency of the forearm ends with the cylindrical side wall of the can, see FIG. 7, such forearms can be made shorter, tenninating such as indicated at 44, thereby permitting a resulting cooperative adjacence of the bent down biceps portions 34 and 35' to an inner surface of said can such as adjacent the outer surface of the inner side wall of said trough which terminates in bead or lip 21 and indicated at 44, thereby to substitute and secure against sidewise and rearward displacement of the wiper device.
Obviously the extent and length of the tongue 29, relative to its operative adjacence to lip 21, can be varied to compensate for the effects of changes in the lengths of the forearms or the cooperative adjacence of the biceps portions to the can lip 21.
A paint laden bristle brush, applicator, or the like can be drawn across the blade edge 45 in the usual and customary manner to remove, scrape or wipe excess paint from such brush.
In its planar or entirely flat condition a wiper device can be afiixed to the top planar surface of the cover 12 for the can 11, see FIG. 5. In this event the blade 24 is provided with an affixation tab 46 projecting centrally from blade 24 and planar therewith. The tab 46 can be affixed to the can cover by any means such as by soldering, cementing, adhesive, or the like. To facilitate detachment of the wiper from the affixed tab, the juncture of the tab with the blade edge is provided with a scored or creased line, or otherwise nicked or partially cut through the metal as indicated by dotted line 47. To detach the wiper from the affixed tab one merely raises the wiper from the surface of the cover and bends it back and forth, alternately, hinged at said scored or nicked line 47, as indicated generally at 48, by dotted lines, see FIG. 6, until the wiper finally breaks away and is disjoined and separated from the tab. Obviously, the size of the wiper device to be affixed to the cover is determined by the cover planar surface area available.
The most simple affixation means would be to merely tape the flat wiper, per se, on the top surface of the can cover by any of the conventional adhesive tapes absent the affixation tab.
Obviously, the wiper can be initially cast or formed in three dimensions or assembled from individual parts, as distinguished from a flat or two dimensional planar configuration, of rigid or flexible material, having the arms and tongue operatively disposed in the aforesaid bent operative angular positions, if desired, see FIGS. 2, 3, and 4.
Some characteristic features of this invention are the provision of a paint brush wiper having an initial flat form adapted to be subsequently readily bent into an operative three dimensional shape; the above paint brush wiper made of material sufficiently flexible to be readily bent by the average persons fingers; such wiper originally cast in a rigid three dimensional shape; a paint brush wiper that is adapted for removable securement over the top of a paint can and held interlockably thereon against accidental displacement forces acting thereon in any direction; and a flexible flat type wiper removably attached to the top or other surface of a container for convenience of shipping and distribution.
Obviously many modifications and variations of the present invention are possible in the light of the above teachings. It is therefore to be understood, that within the scope of the appended claims, the invention may be practiced otherwise than as specifically described.
