2 Claims.

This invention relates to improvements in artists and sign painters brushes; and the invention has reference, more particularly, to an improved brush holder adapted for the interchangeable connection therewith of quill brushes of various sizes.

The invention has for an object to provide a brush holder having a simple, efficient and easily manipulated means for detachably coupling thereto quill brushes; the novel coupling arrangement being such that the quill brush may be quickly and easily mounted and axially centered at the end of the handle portion of the holder, and at the same time being not only firmly and securely gripped against accidental displacement therefrom, but also so as to be rigidly held against lateral play, wobbling or like undesired movement.

The invention has for a further object to pro-- vide a holder for detachably mounting quill brushes in operative relation to the handle portion of such holder, wherein the coupling elements are compactly arranged and retained substantially within the limits of the cross-sectional "area of the handle butt, so that the handle memher, in size and shape, is conventional, and differs little in appearance and bulk from ordinary brush handles to which brush heads are permanently afiixed.

The invention has for another object to provide a holder having quill brush coupling means comprising an axial rigid seating spike and a pair of resilient gripping jaws the members of which are respectively opposed to opposite sides of said seating spike to cooperate therewith in gripping and holding the quill shank of a brush engaged over and upon said seating spike; a sliding sleeve being arranged in connection with the butt of the holder handle to cooperate with said gripping jaws for closing the same.

Other objects of this invention, not at this time more particularly enumerated, will be understood from the following detailed description of the same.

An illustrative embodiment of this invention is shown in the accompanying drawing, in which:

Fig. 1 is a side elevation of the novel holder with a quill brush operatively connected therewith by the novel coupling means according to this invention; Fig. 2 is a fragmentary longitudinal sectional view, drawn on an enlarged scale, showing the novel coupling means in open condition and with the seating spike and jaw elements shown in elevation; Fig. 3 is a view similar to that of Fig. 2, but showing the coupling means as operatively arranged to engage a quill brush with the holder; and Fig. 4 is a view similar to Fig. 3 but with all parts but the seating spike in section.

Fig. 5 is a cross-sectional view, taken on line 55 in Fig. 4.

Similar characters of reference are employed in the above described views, to indicate corresponding parts.

Referring to the drawing, the holder device comprises a handle member IU of the conventional tapered shape. At its butt end, said handle member is provided with a cylindrical buttportion ll ofreduced diameter, thus providing a stop-shoulder l2 at the juncture of the handle member body and said butt-portion thereof. Integral with said butt-portion I I, and extending axially from the free end thereof, is a neck-portion I3 of further reduced diameter. Extending axially outward from said neck-portion I3 is a seating spike [4, which is preferably of a form tapering toward its free outer end. Preferably, although not necessarily, said seating spike M is a separate element, the base end portion l5 of which is aflixed to said handle member structure by driving the same into an axial socket [6 which extends into the neck-portion l3.

Suitably secured in connection with the neckportion l3, so as to extend respectively along opposite sides thereof, are the anchor portions ll of a pair of gripping jaw elements, preferably made from comparatively narrow strips of resilient material, such e. g. as spring steel. Said anchor portions I! are secured against displacement from operative assembled relation to said neckportion l3 by any suitable form of fastening means. For example, the ends of said anchor portions l'l may be provided with angular tangs [8 which are driven into and imbedded in the material of said neck-portion l3. Said anchor portions 11 extend outwardly beyond the extremity of said neck-portion l3. Each jaw element includes an outwardly inclined or oblique camsection I9 from'the outer end of which extends a jaw-section the jaw-section terminating in an inwardly and laterally projected gripper lip 2 i. Preferably the gripper lips are provided with indentations 22 formed in the free margins thereof The said anchor portions IT exceed in length the length of the neck-portion [3, so that flexible portions 11 thereof lie between the extremity of said neck-portion l3 and the junctures of the anchor portions I! with the cam-sections [9. The junctures of the anchor portions H with the cam-sections [9 form at the inner sides of the jaw elements secondary gripper portions 23, adapted to serve purposes presently to be described.

Secured to the butt portion of the handle member ID is a ferrule 24, the same being afiixed to said butt portion II by annular inwardly pressed fastener beads 25. The outer end portion of said ferrule 24 extends in covering or enclosing relation over the neck-portion l3 and the anchor portions l! of the gripping jaw elements.

Telescopically slidable upon the external surface of said ferrule 24 is a slidingly manipulatable sleeve 26. When in retracted position, said sleeve is stopped in normal initial position by the abutment of its inner end against the stopshoulder 2. When thus retracted to normal initial position, the outer end of said sleeve 26 is disposed adjacent to the outer end of the ferrule 24, thus being withdrawn from engagement with the cam-sections l9, so that the inherent resiliency or tension of the jaw elements allows the jaw-sections 20 to spread or flex apart, thus moving the gripper lips 2| to initial open or outwardly spaced relation to the intermediate seating spike H! (see Fig. 2).

The brushes adapted to be interchangeably connected or coupled to the novel holder, comprise the brush body or head 21, the bristles of which are bound into the end of a hollow tubular quill 28 forming the shank of the brush. To mount such form of quill brush in operative coupled relation to the holder, the jaw elements of the latter are disposed in initial open position, as shown in Fig. 2, thus exposing the seating spike M to receive the quill brush. The open end of the quill 28 is first thrust over the free end of said seating spike I4, whereupon the quill is slid downwardly over the latter as far as it will go.

The quill brush having been thus mounted upon the seating spike l4, the sleeve 26 is slid outwardly along the ferrule 24. As the sleeve 28 is moved outwardly, its outer end will engage the outwardly flared or inclined cam-sections IQ of the jaw elements, and as outward movement of the sleeve is continued along said cam-sections IS, the latter will be caused to swing inwardly, thereby, in turn moving inwardly the jaw-sections 20 until the gripping lips 2| thereof respectively engage opposite sides of the walls of the quill 28 so as to tensionally press against the latter and thereby pinch the same against the sides of the seating spike 4 (as shown in Figs. 3 and 4). The indentations 22 of the gripping lips 2| are so disposed as to receive the convexity of the quill walls, thus causing the gripping lips 2| to firmly embrace and hold the quill 28 against both longitudinal displacement from the seating spike as well as against lateral play. The inward movement of the cam-sections l9 also cause an inward deflection of the freely projecting parts ll of the anchor portions thereby causing the secondary gripper portions 23 to impinge upon the adjacent portions of the quill 28, so as to further grip the same at points spaced from the gripping engagement thereof by the gripping lips 2|, thus further securing the quill 28 against displacement, and also embracing the same so as to prevent any wobbling, swaying or other loose movement or play of the quill brush, when operatively connected to the holder.

I am aware that changes could be made in the above described constructon and many apparently Widely different embodiments of this invention could be made without departing from the scope thereof as defined by the following claims; it is therefore intended that all matter contained in the above description or shown in the accompanying drawing shall be interpreted as illustrative and not in a limiting sense.

I claim:-

1. A device of the kind described, comprising a handle member having a neck-portion of reduced diameter, a seating spike projecting axially outward from said neck-portion, a brush head having a hollow shank for removable telescopic engagement over said seating spike, a pair of springy jaw elements having anchor-portions affixed to and extending along opposite sides of said neck-portion, said elements being respectively opposed to opposite sides of said seating spike, said elements terminating in gripping portions spaced longitudinally inward from the free end of said seating spike, cam-sections intermediate said anchor and gripping portions, a ferrule affixed to said handle member with its outer end portion in concentric spaced relation to and enclosing said neck-portion and the anchor portions of said jaw elements, and a slidably manipulatable sleeve on said ferrule and engageable with said cam sections to move said jaw elements relative to said seating spike, thereby to cause said gripping portions to grip and frictionally bind said bru'sh shank to said spike.

2. In a device of the kind described, the combination with a handle member having an axially extending tapered seating spike, a brush head having a hollow shank for removable telescopic engagement over said seating spike, a pair of initially expanded springy jaw elements afiixed to said handle member for projection therefrom along opposite sides of said seating spike with their free end portions terminating short of the free end of the latter, said jaw elements having longitudinally spaced primary and secondary gripper means, said jaw elements having outwardly flared cam-sections intermediate their primary and secondary gripper means, and an actuating sleeve slidably mounted on said handle member and movable to engage and-contract said jaw elements to cause said primary and secondary gripper means thereof to grip and frictionally bind said brush shank to said seating spike at longitudinally spaced points.
