4 Claims.

This invention relates to improvements in brushes and has for its object more particularly the provision of a novel form of camels hair brush or the like made with a metal shaft and adapted to be securely held in the 'cap of a bottle.

A particular object of this invention is the provision of a new form of camels hair brush or the like in which the shaft or handleis made 1 from one piece of metal in which the brush fibres will be securely held and in which the end of the brush will be so constructed that it can be 25 showing the brush and handle partly introduced into the bottle cap.- v

Fig. is a sectional view of the cap and brush assembled.

Fig. 6 is a plan view of another form of blank 30 from which the tube can be made.

'7 isa sideview in elevation of the tube formed from the blank shown in Fig. 6.

In Fig. Lthere is illustrated an elongate blank l of sheet metal or equivalent material provided 85 at one end with rounded corners II, II', a trimmed or :tapered portion l0,-and a laterally extended lip adapted to lap over the other side edge of the blank when rolled into tube form. I! in Figure 2 indicates the U-shaped' form of 40 the tube after the first shaping operation; Fig. 3,

the tube or handle after the second. shaping operation in which the large end of the tube 14 is cylindrical and is defined by the butt seam l5 and the s'mall end of the tube It is tapered and Al defined by an overlapping seam.

This is the important feature of this invention, to form the blank at the smaller end with an overlapping seam and to form the large end of theblankwithabuttseamedgetoedgednstead' or having one continuous butt seam or one continuous overlapping seam for the entire shaft.

The provision of the lap scam in thetapered or shank portion of the brush handle, as will be self-apparent, provides a material amount of reinter-cement therein, which reinforcement at this Figs. l and 6 is that it provides, in eflect,'a reduoed or pointed tip on the cylindrical part of .u

portion of the handle is or importance, 'due to the fact that therein is localized stress tending to buckle the handle during use or abuse. In addition, the extension or the lap joint to the ex-' treme small end of the device aflords a socket I for the bristles II which, when constricted or punched together as shown, will permanently maintain the arrangement of theseveral bristles in proper brush form, as well as assure against loosening and shedding thereof. 1.

The importance of the butt seamwhich defines the cylindrical portion M of the handle lies in the fact that the cylindrical portion is smooth and true and readily insertable within thewell of the cap i9.'- Moreover, the association or u the cylindrical handle'portion ll with the well 20 of the cap I! is characterized by a snug fit and the edges of the portion ll being in abutting relation resist stresses tending to constrict-the cylindrical portion I4 and loosen its fit within, 20 the cap well 20. Assurance against unintentional disassociation of brush and cap members isjthus 'afiorded in a manner well adapted to large scale production of the item.

Referring more specifically to Figs. 4 and '5, V

the cap element 19 is provided, inadditionto the inwardly projecting cylindrical socket ll having the well or bore 20, with a threaded skirt 2! adapted to be threadedly engaged about theneck of a conventional bottle or other receptacle, (not shown) In the modified form of my invention illustrated in Figs. 6 and 7-, the handle blank 23 consists of a parallel-edged portion ,24 terminating at 1, and a trimmed or taperedportion 2t. 21 and ,5 21 areethe rounded-oficomers of the portion 24. The blank shown in Fig. 6 is curled into tubular form as shown in Fig. 7,'the portion 24 becoming the cylindrical portion 28 of the finished handle defined by. the butt seam 29. I. is o a the tapered tubular portion having the lap seam Ihe advantage of the form oi blank shown in the tube, thus facilitating insertion or the handle end in the capsocketportion 2 l oi the cap. In both modifications herein described it will be noted thatthe blank employed is such um the butt-seam-defined portion of the handle is cygo -lindricalandwillhavesmgandsubstantially complete contact with the inner surface or the socket portion 2i 0! the cap Itisobvimisthstchmgelmaybemadein' theiormotthehandleandtheleagthoithell respective butt seams and lap seams without departing from the. spirit of my invention.

What I claim is:

1. A handle fora brush or similar applicator comprising a one piece, quill-like, tubular member formed of sheet stock and provided with a longitudinal seam extending the full length thereof, said tubular member having one end formed to receive and secure the brushingelement proper, an integral cylindrical grip portion at the other end defined by an abutting portion of said longitudinal seam, and a shank portion of reduced diameter intermediate said cylindrical and brush-element-receptive portion, said shank portion being vof tape ing form and defined by a lapped portion of said longitudinal seam,

2. A handle for a brush or similar applicator comprising a one piece, quill-like, tubular mem-- ber formed of sheet stock and provided with a longitudinal seam extending the full length there-; of, said tubular member having one end formed to receive and secure the brushing element proper, an integral cylindrical grip portion at the other end defined by an abutting-portion of said longitudinal seam, said cylindrical portion being diagonally cut away at its extremity to provide, in efiect, a tip of slightly tapered form adapted to facilitate insertion of said cylindrical portion within a member having a complementary cylindrical bore, and a shank portion of reduced diameter intermediate said cylindrical and brushelement-receptive portion, said shank portion being of tapering form and defined by a lapped portion of said longitudinal seam.

3. A handle for a or similar applicator comprising a one piece, quill-like, tubular member formed of sheet stock and provided with a longitudinal seam extending the full length thereof, said tubular member having one end formed to receive and secure the brushing element proper, an integral cylindrical grip portion at the other end defined by an abutting portion of said longitudinal seam, said cylindrical portion being notched at its extremity to provide, in effect, a"

tip of slightly tapered form adapted to facilitate insertion of said cylindrical portion within a member having a complementary cylindrical bore, and a shank portion of reduced diameter intermediate said cylindrical and brush-element-receptive portion, said shank portion being of tapering form and defined by a lapped portion 01 said longitudinal seam.

4. A handle for a brush or similar applicator comprising a one piece, quill-like, tubular mem-- said socket portion, being defined by a lap-joint portion of said longitudinal seam.
