PAINT BRUSH AND DRILL CHUCK ADAPTER COMBINATION Filed Jan. 5. 1964 H Mi ll ii INVENTOR.

" United States Patent 3,252,174 PAINT BRUSH AND DRILL CHUCK ADAPTER COIVIBINATION Fred W. Schoepske, Jr., 1206 Western St., Waterloo, Iowa Filed Jan. 3, 1964, Ser. No. 335,583 Claims. (Cl. -1)

This invention relates to a novel paint brush and drill chuck combination for use in drying paint brushes by centrifugal action.

The practice heretofore, has been to employ paint brush and drill chuck adapter combinations, wherein the adapters were on the ends of the handles of the brushes and in line with the longitudinal centerlines of the handles, so that the brushes were rotated, by drills, on the axes of their centerlines, and paint was thrown, by centrifugal action,

laterally from the brushes, and the bristles tended to be undesirably displaced laterally, by the same action, so that, on drying the bristles were splayed, and otherwise disarranged.

The primary object of the invention is the provision of a more eflicient, more effective, and quicker acting combination of the kind-indicated, which not only throws off paint present in a paint brush, as the same is rotated, but flulfs and straightens the bristles of the brush.

Another object of the invention is the provision of a combination of the character indicated above, wherein the drill chuck adapter extends laterally from the head of the paint brush, preferably at the center-of-gravity of the brush, so that the brush is rotated on the axis of this center, the adapter comprising a threaded socket, secured to the brush, and a rotatable element'threaded into the socket and engageable in the chuck of a drill, the direction of the threads being such that the rotation of the drill chuck tightens the element in the socket and prevents disengagement of the element from the socket while in use.

Other important objects and advantageous features of the invention will be apparent from the following description and the accompanying drawings, wherein, for purposes of illustration only, a specific form of the invention is set forth in detail.

In the drawings:

FIGURE 1 is an exploded and fragmentary perspective view of a combination of the present invention;

FIGURE 2 is a schematic side elevation showing said combination assembled and chucked in a drill, a protective container for the brush, while being rotated, being shown in phantom lines; and,

FIGURE 3 is an enlarged transverse section taken onthe line 3-3 of FIGURE 2.

Referring in detail to the drawings, the illustrated combination comprises a conventional form of paint brush 10, having a handle 12 which merges, at its distal end, with a wider head 14,- in which the bristles 16 are secured.

The brush handle 12 is formed, adjacent to the head 14, wit-h a centered blind bore 18, which is preferably located at the center of gravity of the brush 10, and opens to one side of the handle. A threaded metal socket 22 extends the length of and is suitably secured in the blind bore 18 and has, on its outer end, a flat generally circular lateral flange 24. The flange 24 bears against the handle side 20 and has, at equally circumferentially spaced locations, triangular teeth 26, which are driven into the handle 12, so as to anchor the socket 22 in place.

The flange 24 serves as a wear plate and stop for a shoulder 28, on a rotatable element 30, which is defined by a reduced diameter threaded terminal 32, on the distal 3,252,174 Patented May 24, 1966 end of the element, which is adapted to be threaded into the socket 22. The direction of the threads of the socket and of the element terminal are-such, with regard to the direction of rotation of the element when secured in the chuck 34 of a power drill D, that the rotation of the chuck serves to tighten the element in the socket and prclude their disengagements during a brush drying operation. 1

In operation, because the brush extends crosswise of and at right angles to the axis of rotation of the element 30, centrifugal force acts to throw the paint off the free ends of the bristles, so that more paint is thrown more quickly off the bristles, than in the prior practices mentioned hereinabove. Further, the same centrifugal force acts positively to pull the bristles lengthwise, so that the bristles are straightened and air flutied, rather than distorted and splayed.

Although there has been shown and described a preferred form of the invention, it is to be understood that the invention is not necessarily confined thereto, and that any change or changes in the structure of and in the relative arrangements of components thereof are contemplated as being within the scope of the invention as defiened by the claims appended hereto.

What is claimed is:

1. Apparatus comprising a brush having an elongated handle with brush bristles extending from one end of said handle, a laterally opening integral socket within said handle of said brush at its center of gravity, and means inlocked engagement with said socket for. rotating said brush about an axis through said socket.

2. Apparatus comprising a brush having an elongated handle with brush bristles extending from one end of said handle, a laterally opening integral socket within said handle of said brush at its center of gravity, and

means in locked engagement with said socket for rotating said brush about an axis through said socket, said means including a rotatable element having a terminal locked to the socket, and a drill having a chuck in which the rotatable element is secured.

3. Apparatus comprising a brush having an elongated handle with brush bristles extending from one end of said handle, a laterally opening integral socket within said handle of said brush at its center of gravity, and means in locked engagement with said socket for rotating said brush abzout an axis through said socket, said means including a rotatable element having a threaded terminal removably threaded into said socket.

4. The combination of claim 3, wherein said handle is formed with a laterally opening bore, and said socket is secured in the bore, said socket having a lateral annular flange engaged with one side of the handle, said element terminal being smaller in diameter than an adjacent part of the element so as to define a stop shoulder adapted to engage said flange.

5. The combination of claim 3, wherein said handle is formed with a laterally opening bore, and said socket is secured in the bore, said socket having a lateral annular flange engaged with one side of the handle, said element terminal being smaller in diameter than an adjacent part of the element so as to define a stop shoulder adapted to engage said flange, the threads of the socket and the threads of the element terminal being arranged so that rotation of the element tightens the terminal in the socket.

adapted to engage said flange, said flange having teeth securably engaged in the said one side of the handle.

7. A paint brush comprising an elongated handle, brush bristles connected to one end of said handle, a laterally opening bore in said handle at the center of gravity of said brush, and socket means integrally connected to said handle Within said bore for locking engagement with a device for rotating said brush about an axis through said bore.

8. A paint brush in accordance with claim 7 wherein said socket means includes a lateral annular flange engaged with one side of said handle, and a threaded bore for threaded engagement with said rotating device.

9. A paint brush in accordance with claim 8 wherein said socket flange has teeth securably engaged in said one side of said handle.

10. A paint brush comprising an elongated handle, brush bristles connected to one end of said handle, and

laterally opening socket means integrally mounted on said handle at the center of gravity of said brush for locking engagement with a device for rotating said brush about an axis through said socket means.
