3 Claims. (Cl. -176) This invention relates to improvements in cleaning articles in the nature of brushes and the like.
An object of the invention is to provide a novel and improved cleaning article in the nature of a brush and the like, in which there is a brush head or body carrying a plurality of bristles extending outwardly therefrom, or the like, and provided with a novel handle and mode of engagement of the handle with the brush head.
Another object of the invention is to provide a novel and improved brush in which there is a handle extensible outwardly at any desired degree of angularinclination relative to the brush head or body, and elongated deformable means engaging body of the brush and its handle portion in a novel manner, for greatest utility and convenience.
A further object of the invention is to provide a novel and improved brushing device having a curved brush body with upper and lower body surfaces and a plurality of bristles extending outwardly from the lower body surface at least, the brush body having a groove formed in its edge surface, and extending all around the waist portion of the brush body, elongated wire means being disposed in the waist groove and extending all therethrough, the two ends of the wire means being brought into mutually overlapping relationship and then extended outwardly into an opening formed in a handle means, the handle means being thus carried by the wire means and due to the flexibility of the wire means, being readily adjustable angularly relative to the brush body.
Still another object of the invention is to provide a novel and improved brushing device, in which there is a handle provided with an axial opening to receive the paired twisted together ends of a wire handle support which in turn extends around the brush body and is seated in a groove formed in the edge thereof, and with means in the handle for so engaging the wire, that by a simple turn or other desired motion thereof, the wire is untwisted sufficiently to permit disengagement from the brush head or body, for ready engagement with one or more other brush bodies as desired.
Still a further object of the invention is to provide a novel and improved brushing device of the character described, which is simple in design, inexpensive to manufacture, and very rugged and convenient in use.
These and other objects and advantages of the invention will become apparent from the following description of a preferred embodiment of the invention, as illustrated in the accompanying drawings, forming part hereof, and in which,
Figure l is a top plane view taken with a portion of the brush head broken out to illustrate the construction.
Figure 2 is a front elevational view of the brush shown in Figure 1.
Figure 3 is a fragmentary front elevational view similar to that of Figure 2, but with the brush handle portion sectioned to show the interior construction.
Figure 4 is a sectional elevational view taken on plane 4-4 of Figure 3,
Figure 5 is a sectional view similar to that of Figure 3, but showing a modified form of the invention.
In connection with the manufacture and use of brushes, such as used for cleaning and scrubbing, various factors are primarily of importance in order to achieve optimum results. Such a brush should be small and compact in size, so that it may be readily stored when not in use, and shaped so as to enter into narrow or confined spaces in which cleaning is to be done. Further, it should have a certain degree of flexibility to permit reaching all types of surfaces, with inherent adjustability for this purpose. However, the cost of manufacture of the brush is of utmost importance, since if too much expense is encountered in achieving these features, the brush cannot be sold at a reasonable price, and will not be desirable from the consumers standpoint. Accordingly, the present invention discloses such a brush, which may be made at very low cost, yet is easily adjustable to fit any corner or space, and yet is light in weight and compact in size.
In order to understand clearly the nature of the invention, and the best means for carrying it out, reference may now be had to the drawings, in which like numerals denote similar parts throughout the several views.
As shown, there is a main major brush head or the like 10, and a major brush handle or the like 12, suitably cooperatively coacting in the manners described hereinafter. The brush head 10 may be of circular contour as seen in plan in Figure 1, with a top edge 14 made plane or otherwise contoured, as needed, and a lower edge or face 16, substantially parallel to the top face 14, and spaced therefrom by the thickness of the brush head 10, with a large number of bristles 17 projecting from face 16 downwardly as seen in Figures 2 and 3. The brush head 10 may have suitable openings formed in its lower face 16, to receive the bristles 17 either singly, or in groups, so as to permit retention of the bristles permanently in the brush head 10. The brush head is thus adapted for cleaning or brushing of any desired surface, with the aid of suitable detergents, soaps, and liquids.
A peripheral groove 18 isforrned all around the side edge of the brush head 10, the groove being sufiiciently indented as to permit the reception therein of a wire, cord, or cable member 20 without undue projection beyond the periphery, or no such projection as preferred. The wire member 20 has thus a pair of ends 22 and 24, as seen best in Figures 1 and 3, the wire ends being twisted around each other in the manner shown best in Figure 3, for a substantial number of such twists or turns, giving a rather snug degree of tightness in the grip of the encircling wire band or belt 26 in its engagement with the belt receiving groove 13 of the brush head 10.
There is a handle member 12, the outer end of which is shown at 13, while the inner end 21 of the handle member is extended to a position near the brush head 10, but spaced slightly therefrom as shown. An axial bore 40 is formed through the inner end portion 21 of the handle 12, as shown best in Figures 3 and 4, to receive the twisted end portions 22 and 24 of the wire or belt member 20, so that the outermost ends 42 of the twisted portions 22 and 24 which combine to form twisted section 26, thus extend all the way in to the floor or end of the bore 40. As shown best in Figure 5, according to a modified form of the invention, a conical or similarly shaped member 45 carried on a base 47, either pressed into position against the floor of the recess 40, or anchored thereagainst by projections 50 extending into the floor of recess 40. As the twisted portion 26 of the wire cable 20 is pushed into the bore 40, it is seen that the conical cam 47 will tend to spread apart the two ends innermost of the twisted cable section generally indicated at 26, so as to cause them to dig into the sides of the bore 40, thus securely anchoring them therein against dislodgment. Of course, it is Patented Sept. 4, 1956 understoodthatthespreader cone 47 may be dispensed with, according to another form of the invention, and the y bore of recess 40 be made only sufficiently great to receive the cable twist section 26 in a tight snug fit, to hold them in engagement,
A ferrule 30 issn'uglysecuredpver the proximal end 21 of the handle 12, and hasa left end wall 34 as seen best in Figures 3 and 4, formed with openings 36 and 38 to receive the twisted cable portions 22 and 26 in the manner shown in Figure 4, the openings 36 and 38 communicating with each other ,at the location of contact, but retaining some portion as at 41 of the ferrule wall 34 in the manner seen best, in Figure v4. Ribs 46 may be formed in the outer surfaces of the ferrule as seen .in Figure 4, to enhance the hand gripor to permit of application of a wrench if desired to hold or turn the ferrule in relation to the twisted cables 22 and'26 engaged therein. In this manner, it is possible to either enhance the degree of twist about the equatorial groove 18 of the brush head, or to untwist several turns thereof without removing the twisted. inner ends 42 of the cable from the bore 40. Hence, any incidental looseness which may develop due to any reason may be corrected in this'manner. Also, it is seen that by untwisting a few of the turns, such as those which are between wall 34 and the brush head, it is possible to loosen the band 20 sufficiently to remove it from the brush head,'so that the brush head may be replaced with another, or soaked or cleaned, as needed.
It is also seen that due to the interconnecting openings 36 and 38'engaging the twisted cables as at 26, the cables are in effect threaded into wall 34, so that ferrule 30 may act as a tightening nut to threadedly engage or disengage the mating parts, or to enhance the engagement or disengagement. The ferrule may of course also have inwardly projecting ribs like ribs 46, but projecting inwardly and pressed into the surface of the handle 12 to further secure the ferrule to handle 12 if desired.
The brush thus formed is readily adjustable to any desired angle of inclination of the brush handle 12 relative to the top of the brush head 10, as indicated by arrows 15 in Figure 2, so that it may be at right angles to the plane of surface 14 of the handleengaging brush head 10, or parallel thereto, or extendingdownwardly or upwardly therefrom, all by merely adjusting the orientation of the handle, the wire cable 20 being sufl'iciently deformable to permit of such adjustment. Hence it can be used for all possible surfaces which are to be cleaner or brushed, and
will easily reach into corners, or up onto surfaces which One handle are above the head of the cleaning operator. 12 may be sold with several brush'heads of varying shapes,
each replaceable as needed, or one brush head may be sold with several handles 12, of various lengths, to use in different places.
Although I have described my invention in specific terms, it will be understood that changes may he made in the size, shape, materials and arrangement without departing from the spirit and scope of the invention as claimed.
