PAINTBRUSH Filed June 9, 1952 NVENTR. ff/am Gil/wem United States Patent PAINTBRUSH Hans G. Lassen, Chicago, Ill., assignor to Ernest L. Hawkins Application June 9, 1952, Serial No. 292,449 2 Claims. (Cl. 15-202) This invention relates to paint brushes.

The principal object of this invention is to provide an improved separable paint brush having two engaging brush heads, wherein the brush heads may be separated for readily cleaning the brush, and wherein the brush heads may be readily, simply and rmly secured together with the brush heads in correct relative position.

The separable paint brush of this invention includes a pair of brush heads having mating and engaging side surfaces. Each brush head includes a ferrule having an engaging inner side, an outer side, a first curved end and a second curved end having a curved extension, bristles carried at one edge of the ferrule and a handle portion carried at the other edge of the ferrule. A screw is carried by the first curved end of one of the ferrules and extends outwardly therefrom, the curved extension of the other ferrule having a hole therein. The arrangement is such that, when the brush heads are brought together with their mating and engaging sides in contact, the curved extensions of the ferrules overlie the first curved ends of the ferrules and the screw extends through the hole. The overlying curved extensions of the ferrules operate to position the brush heads with respect to each other. A nut is carried by the screw for removably securing the brush heads together. The first curved end of the other ferrule may be provided with a pin which extends through a hole in the curved extension of the iirst ferrule, this pin and hole operating in conjunction with the screw and hole to provide further means for mating and securing together the pair of brush heads.

Further objects of this invention reside in the details of construction of the paint brush and in the cooperative relationship between the component parts thereof.

Other objects and advantages of this invention will become apparent to those skilled in the art upon reference tohthg accompanying specification, claims and drawing, in w 1c Fig. 1 is a perspective view of the assembled brush of this invention;

Fig. 4 is a sectional view taken substantially along the line 4 4 of Fig. 1;

Fig. 5 is a perspective view of the mating ferrules; and

Fig. 6 is an exploded perspective view of the two brush heads in disassembled condition.

The brush of this invention is generally designated at 10 and it includes a pair of brush heads 11 and 12 which have mating and engaging side surfaces so that when the two brush heads are secured together a single unitary brush is provided.

The brush head 11 includes a ferrule 13 which may be formed of a single piece of metal. The ferrule has an engaging inner side 14, a first curved end 15, an outer side and a second curved end 16 having a curved extension 17. The inner side 14 has a curved tab 18 which may be secured to the curved end 16 by welding or the like to form a solid and complete ferrule. The first curved end has a pin 19 extending outwardly therefrom, the pin being suitably secured in place as by welding. The curved extension 17 has a hole 20 therein.

The brush head 12 is similar in construction to the brush head 11 and it includes a ferrule 21 also preferably formed of a single piece of metal and having an engaging inner side 22, a first curved end 23, an outer side 24, and

. heads having mating and engaging side a second curved end 25 provided with a curved extension 26. The inner side 22 is provided with a curved tab 27 which may be suitably secured, as by welding, to the second curved end 25 to form a complete and rigid ferrule. Here the first curved end 23 of the ferrule 21 carries a screw 28 extending outwardly therefrom, the screw 2S being secured in place by welding or the like. The curved extension 26 of the ferrule .21 is provided with a hole 29.

The ferrule 13 is secured to the brush head 11 by rivets 31, the brush head 11 being provided with a suitable handle 32. The other ferrule 21 is secured to the brush head 12 by rivets 33. Brush bristles 34 are suitably carried at the lower edge of the ferrule 13, being secured in the ferrule 13 in conventional manner, including the use of rivets 35. Likewise, the lower edge of the ferrule 21 carries bristles 36, the bristles being secured in the ferrule 21 in conventional manner, including the use of rivets 37.

When the mating and engaging side surfaces of the brush heads 11 and 12 are brought together, the curved extension 17 of the first ferrule 13 overlies the first curved end 23 of the second ferrule 21 and. the curved extension 26 of the second ferrule 21 overlies the first curved end 15 of the first ferrule 13. These curved extensions 17 and 26 therefore operate to maintain the two brush heads 11 and 12 in proper relation when they are brought together. At the same time, the pin .19 of the first ferrule 13 extends through the hole 29 in the curved extension 26 of the second ferrule 21 and the screw 28 of the second ferrule 21 extends through the hole 20 of the curved extension 17 of the first ferrule 14. The pin and screw extending through these holes also operate to locate the two brush heads 11 and 12 with respect to each other. A nut 4l) is screw-threadedly mounted on the screw 28 for removably securing the two brush heads 11 and 12 together, the brush heads being clamped together by the action of the nut.

Thus to assemble and disassemble the separable paint brush of this invention for cleaning purposes and the like, all that is necessary is to manipulate the nut 40. The brush, when so readily assembled, is compact and strong in construction and because it is substantially symmetrical about its central axis, it is a substantially completely balanced brush which is easy to use. If desired, when the brushes are disassembled, either brush head 11 or 12 may be used as a paint brush and this is particularly adn vantageous where a thin brush is desired.

While for purposes of illustration one form of this invention has been disclosed, other forms thereof may become apparent to those skilled in the art upon reference to this disclosure and, therefore, this invention is to be limited only by the scope of the appended claims.

I claim as my invention:

1. A separable paint brush comprising, a pair of brush heads having mating and engaging side surfaces, each brush head including a ferrule having an engaging inner side, an outer side, a first curved end and a second curved end having a curved extension, bristles carried at one edge of the ferrule and a handle portion carried at the other edge of the ferrule, a screw carried by the first curved end of one of the ferrules and extending outwardly therefrom, the curved extension of the other ferrule having a hole therein, the arrangement being such that, when the brush heads are brought together with their mating and engaging sides in contact, the curved extensions of the ferrules overlie the first curvedl ends of the ferrules and the screw extends through the hole, and a nut carried by the screw for removably securing the brush heads together.
