Abstract
A paint brush holder having a handle which has a rounded end. Two opposed clamping plates are clamped to the rounded end by a machine screw and wing-nut. The machine screw passes through openings in the clamping plates and in the rounded end, at a location at the center of curvature of the rounded end. The clamping plates have inturned flanges at their free ends which clamp a brush head between them. By loosening and tightening the single wing-nut, the position of the clamping plates and brush can be adjusted and the plates can then be clamped to secure the brush in a desired position.

BP File No. 6211-002 Title: BRUSH WITH ADJUSTABLE AND REPT.ArRART.R HEAD
FIELD OF THE lNV~ ON
This invention relates to a brush handle and more particularly to a brush handle having an adjustable brush head and allowing for interchangeability of the brush/bristle units.
RA~KG~ouND OF THE INVENTION
The paint brush remains a staple tool in the quiver of both the professional and amateur painter alike.
While the paint brush has been around for generations, it has changed very little. Unfortunately neither have the characteristics of painting. Painting remains an inherently messy task. Paint tends to drip onto the hands of the painter and the bristles require cleaning to preserve and extend their working life.
In the hands of an amateur, the life of paint brush tends to decrease. Typically, an amateur does not give the care and cleaning required to preserve a brush.
For example, letting a brush laden with paint dry can virtually ruin the brush. Even with attentive care, the bristles of a brush tend to wear out. Typically, a paint brush includes a brush head, formed from bristles held together by an adhesive such as rubber glue, connected to a plastic or metal handle by means of a ferrule, which can also be of metal. Once the bristles wear out or are ruined through neglect, the entire brush assembly is discarded.
In today's environmentally conscious world, this does not amount to sound practice.
The other problem encountered with paint brushes today concerns the action of painting. While a brush provides a good vehicle for holding and transferring paint to the work surface, the law of gravity inevitably results in paint dripping onto the hand or arm of the painter, _ - 2 -especially for the amateur painter. The law of gravity seems to exact a higher toll when the brush is used in restricted areas and at awkward angles, e.g. upside down for painting the underside of a surface, such as a counter top, or a ceiling.
These problems are not new to painters and various devices for providing an adjustable angle between the brush head and handle have been described in the prior art. Two such devices, of which I am aware, however, have been of rather complex construction and have failed to completely solve the problems in this field of art.
United States Patent No. 3,604,044, which issued to Johnson on September 14, 1971, discloses a paint brush with a moveable head. The patent teaches a device in which the handle has a ball which mates with the socket in the brush head to provide an adjustable range over 360 about the axis of the handle. To fix the brush head in any one of the multitude of positions available, the brush head includes a wing-nut type screw having a concave end. By tightening the screw, the ball is pressed against the wall of the socket thereby locking the position of the brush head. There are two problems with the Johnson device.
First, while providing a multitude of positions, there are many brush head positions which are awkward and in the hands of an amateur may prove unworkable. Secondly, and more importantly, the ball and socket arrangement requires a complicated manufacturing and assembly procedure. To engage the ball in the socket, the brush head is fabricated as two halves and the handle is engaged by "sandwiching" the ball in the socket. Furthermore, once the bristles wear out or are ruined, the entire brush must be replaced.
The other teaching of which I am aware is that disclosed by Goard in United States Patent No. 1,899,690, which issued on February 28, 1933. The Goard patent also discloses a brush with a moveable head, in this case a typewriter cleaning brush. The Goard patent teaches a 2111~2 device in which the brush head can move in a plane coincident with the handle axis, i.e. a fan-like movement.
The position of the brush head is locked using a combination of radial grooves formed in the handle which accept a longitudinal lug pressed into one of the jaws. A
rivet connector rigidly presses the jaws into the brush/bristle assembly. The patent does not teach a device which allows the brush/bristle assembly to be replaced without having to discard the entire brush. As is evident, the Goard device also suffers from two deficiencies.
First, the mechanism for locking the brush head into one of the positions i not robust enough for a painting environment. By exerting sufficient pressure, the brush head can slip from its current position. Moreover, with repeated use, the lug will tend to wear out the radial grooves merely by abrasive action. This effect is more pronounced if the handle is fabricated from a material such as nylon or plastic. Secondly, the patent does not teach a device which allows replacement of the brush head assembly.
As discussed above, various types of adjustable brushes have been proposed. Yet to my knowledge, no such brush has achieved wide spread acceptance or commercial success among professional or amateur painters. Moreover, the known devices have failed to combine the concepts of an adjustable brush head with an interchangeable brush head. Thus, for whatever reason, be it relatively high cost to manufacture or inconvenience of use, no one has yet met the need for a simple brush handle that allows the angle of the brush head to be easily adjusted and which provides for replacement or interchangeable brush heads to be used.
Accordingly, it is an object of the present invention to provide a simple and easy to manufacture devicé which allows the brush head to be removed for cleaning or replacement without discarding the entire brush and which includes an adjustable brush head for 21~1262 accessing hard to reach or awkward painting work surfaces.
SUMHARY OF THE lNv~ lON
In one of its embodiments the invention provides a paint brush holder assembly comprising:
(a) a handle having a pair of substantially flat surfaces, (b) said handle having a rounded end and an aperture in said rounded end extending between said surfaces at a location adjacent said rounded end, (c) a pair of clamping plates, each having a handle-clamping portion, one handle clamping portion overlying each of said flat surfaces, and each handle-clamping portion having an aperture therein, said apertures all being aligned, (d) a pivot shaft extending through all of said apertures for allowing said clamping plates to pivot about said handle, (e) means associated with said pivot shaft for clamping said clamping plates to said handle to lock said clamping plates in a desired position relative to said handle, (f) said clamping plates having brush-clamping portions extending from said handle-clamping portions and adapted, when said handle-clamping portions are clamped to said handle, to clamp and secure between them a paint brush head.

DE~ATT.~n DESCRIPTION OF PREFERRED EMBODIMENTS
The present invention comprises a paint brush assembly 1. As shown in the exploded view of Fig. 1, the brush assembly 1 includes a handle 10, first and second clamps 30a,30b, pivotable locking means 40 and a brush head 50.
The handle 10 is of one-piece construction. It can be formed from a lightweight metal such as aluminum or molded from plastic. A handle 10 formed from metal has the advantage of durability. Moreover, since it is the brush head 50 which will wear out, the handle 10 should be made to last. Plastic injection molding, however, does provide for an inexpensive, yet durable construction.
The handle 10 should have a shape which not only fits the painter's hand, but also feels comfortable. As shown in Fig. 1, the handle 10 is flat and long as most traditional brush handles. The handle 10 has a rounded brush-end 12 (having a circular profile), a grip portion 14, and a grip-end 16. The brush-end 12 includes a first aperture 18 which accepts the pivotable locking means 40 as will be discussed below. The first aperture 18 can 21112~2 _ - 6 -simply be a drilled through hole with a diameter adapted to accept the pivotable locking means 40. Aperture 18 is located at the center of the circular arc defined by the end of brush-end 12.
The grip portion 14 of the handle 10 includes a number of second apertures 20. The second apertures 20 provide convenient means for suspending the brush assembly 1 inside a paint container (not shown) using a brush holder device (not shown). The grip portion 14 includes a number of apertures 20 so that the position of the brush assembly 1 as suspended in the paint container (not shown) can be easily varied. Moreover, the second apertures 20 provide the secondary benefit of making the handle 10 lighter. Referring still to Fig. 1, the grip-end 16 of the handle 10 includes a third aperture 22. The third aperture 22 provides a convenient means for hanging the brush assembly 1 on a display rack (not shown) or a storage rack (not shown).
The first and second clamps 30a,30b connect to the opposing faces of the brush-end 12 of the handle 10.
The clamps 30a,30b include face plates 32a,32b which press against the opposing faces of the brush-end 12 of the handle. The face plates 32a,32b each include aperture 24a,24b which are located on the same center as the first aperture 18. The apertures 24a,24b, along with the first aperture 18, receive the pivotable locking means 40 as discussed below.
Referring still to Fig. 1, the clamps 30a,30b also include jaw plates 34a,34b. The jaw plates 34a,34b are formed as an integral part of the clamps 30a,30b and are joined to plates 32a,32b by outwardly sloping portions 35a,35b respectively. As shown in Fig. 1, the jaw plates 34a,34b are shaped to accommodate the brush head 50. To securely grip the brush head 50, the jaws 34a,34b include inwardly directed flanges 36a,36b. As shown in Fig. 1 and Fig. 2, the flanges 36a,36b terminate in teeth 38a,38b which bite into the brush head 50 and prevent the brush _ -- 7 head 50 from moving or shifting its position within the clamps 30a,30b.
The shape of the flanges 36a,36b can be varied depending on the design of the brush head 50. Conventional brush heads 50 are made by hardening the rear ends of the bristles 52, holding them together in a fixture and dipping them into glue. Flanges 36a,36b with teeth 38a,38b are ideal for gripping such conventional brush heads 50 as shown in Fig. 2. Brush heads 50 can also be made by using a ferrule (not shown) to enclose the glue dipped ends of the bristles 52. The ferrule (not shown) can be metal or plastic. By including a groove in the ferrule (not shown) adapted to fit the flanges 36a,36b, the brush head 50 can be secured by the clamps 30a,30b without the need for the teeth 38a,38b.
The clamps 30a,30b function together with the pivotable locking means 40 to secure the brush head 50 to the handle 10. As shown in Fig. 1 and Fig. 2, the pivotable locking means 40, in its simplest form, comprise a machine screw 42 with a matching wing-nut 44. The machine screw 42 passes through the aperture 24a in the first clamp 30a, the aperture 18 in the handle 10 and the aperture 24b in the second clamp 30b. The wing-nut 44 screws onto the threaded end of the machine screw 42. By tightening the machine screw 42 and the wing-nut 44 combination, the clamps 30a,30b bite into the brush head 50 thereby securing it to the handle 10.
As will now be apparent, the pivotable locking means 40 allow the position of the brush head 50, to be varied. As shown in Fig. 3, the brush head 50 as secured by the clamps 30a,30b, can rotate about the axis of the machine screw 42. The machine screw 42 provides an axis about which the clamps 30a,30b and brush head 50 can pivot. By slightly loosening the machine screw 42 and wing-nut 44 combination, the position of the clamps 30a,30b and brush head 50 can be adjusted through a 180 range. To fix the position of the brush head 50, the user simply tightens the machine screw 42 and wing-nut combination 44. In this way, the first embodiment of this invention provides pivotable locking means 40 which include means to secure the brush head 50 to the brush handle 10 and also provide means for adjusting and locking the position of the brush head 50. The rounded end 12 permits the above described pivoting.
Fig. 4 illustrates another aspect of the present invention. In this aspect of the invention, the brush assembly 1 includes separate adjusting means 60 for varying the position of the brush head 50. The adjusting means comprise two brush position apertures 62, and fastening means 64. The brush position apertures 62 are located along an axis in the brush-end 12 of the handle 10 and in the faceplates 32a,32b of the clamps 30a,30b as shown in Fig. 4. One of the apertures 62 can be positioned such that the brush head 50 is set at a 45 angle to the handle 10 as shown in Fig. 6, and another aperture 62 can be positioned such that the brush head 50 is set at a 60 angle to the handle 10 (not shown). The fastening means 64 can comprise any suitable fastener, and as shown in Fig.
4 and Fig. 5 may simply be a second machine screw 66 and a second machine nut 68. This second embodiment of the present invention offers the advantage of providing fixed positions for adjusting the position of the brush head 50.
However it does require another fastener and it is limited as to the number of positions which can be adopted.
From the previous description, it is evident that the present invention presents a simple, yet effective brush assembly with an adjustable and replaceable brush head. In addition, the invention can be easily manufactured using known fabrication techniques such as metal stamping or plastic molding. Although the present invention has been described in detail, it is clearly understood that the spirit and scope of the present invention is limited only by the terms of the following claims.

The shape of the flanges 36a,36b can be varied depending on the design of the brush head 50. Conventional brush heads 50 are made by hardening the rear ends of the bristles 52, holding them together in a fixture and dipping them into glue. Flanges 36a,36b with teeth 38a,38b are ideal for gripping such conventional brush heads 50 as shown in Fig. 2. Brush heads 50 can also be made by using a ferrule (not shown) to enclose the glue dipped ends of the bristles 52. The ferrule (not shown) can be metal or plastic. By including a groove in the ferrule (not shown) adapted to fit the flanges 36a,36b, the brush head 50 can be secured by the clamps 30a,30b without the need for the teeth 38a,38b.
The clamps 30a,30b function together with the pivotable locking means 40 to secure the brush head 50 to the handle 10. As shown in Fig. 1 and Fig. 2, the pivotable locking means 40, in its simplest form, comprise a machine screw 42 with a matching wing-nut 44. The machine screw 42 passes through the aperture 24a in the first clamp 30a, the aperture 18 in the handle 10 and the aperture 24b in the second clamp 30b. The wing-nut 44 screws onto the threaded end of the machine screw 42. By tightening the machine screw 42 and the wing-nut 44 combination, the clamps 30a,30b bite into the brush head 50 thereby securing it to the handle 10.
As will now be apparent, the pivotable locking means 40 allow the position of the brush head 50, to be varied. As shown in Fig. 3, the brush head 50 as secured by the clamps 30a,30b, can rotate about the axis of the machine screw 42. The machine screw 42 provides an axis about which the clamps 30a,30b and brush head 50 can pivot. By slightly loosening the machine screw 42 and wing-nut 44 combination, the position of the clamps 30a,30b and brush head 50 can be adjusted through a 180 range. To fix the position of the brush head 50, the user simply tightens the machine screw 42 and wing-nut combination 44. In this way, the first embodiment of this invention provides pivotable locking means 40 which include means to secure the brush head 50 to the brush handle 10 and also provide means for adjusting and locking the position of the brush head 50. The rounded end 12 permits the above described pivoting.
Fig. 4 illustrates another aspect of the present invention. In this aspect of the invention, the brush assembly 1 includes separate adjusting means 60 for varying the position of the brush head 50. The adjusting means comprise two brush position apertures 62, and fastening means 64. The brush position apertures 62 are located along an axis in the brush-end 12 of the handle 10 and in the faceplates 32a,32b of the clamps 30a,30b as shown in Fig. 4. One of the apertures 62 can be positioned such that the brush head 50 is set at a 45 angle to the handle 10 as shown in Fig. 6, and another aperture 62 can be positioned such that the brush head 50 is set at a 60 angle to the handle 10 (not shown). The fastening means 64 can comprise any suitable fastener, and as shown in Fig.
4 and Fig. 5 may simply be a second machine screw 66 and a second machine nut 68. This second embodiment of the present invention offers the advantage of providing fixed positions for adjusting the position of the brush head 50.
However it does require another fastener and it is limited as to the number of positions which can be adopted.
From the previous description, it is evident that the present invention presents a simple, yet effective brush assembly with an adjustable and replaceable brush head. In addition, the invention can be easily manufactured using known fabrication techniques such as metal stamping or plastic molding. Although the present invention has been described in detail, it is clearly understood that the spirit and scope of the present invention is limited only by the terms of the following claims.
