'1 Claims. (01. 15-192) This invention relates to brushes 01' the paint brush type.

It is an object of the present invention to provide an improved brush construction employing a combined bristle and handle securing unit of reinforced yet simple character which will not tend to spring or yield and which will secure the bristles and secure the handle without the necessity of employing nails, rivets and the like.

A further object of the invention is to providea brush of this kind employing a bristle-securing and handle-securing unit which is made of a plurality of parts readily secured together as a unit in a simple and efiicient manner.

A still further object of the invention is to provide a brush of this kind wherein the bristl securing unit may be made of minimum size and into which the butts of the bristles are projected into the ferrule only to a limited extent, making it possible to use a shorter length of bristle than in the case of usual and conventional structures.

A still further object of the invention is to pro vide a brush structure wherein the handle may be formed of plastic material and moulded and secured to the handle receiving portion of the holding unit in a simple durable and secure man'- ner.

A still further object of the present invention is to provide a brush of this character in which the bristles may be secured in the ferrule and the handle secured to a receiving element in separate operations and the two parts secured together in a simple operation to form the complete brush.

With these and other objects in view the invention generally comprises a bristle holding unit.

including a ferrule into which the butts of the bristles may be projected, a bristle securing ele- Fig. 7 is a transverse section taken through the unit shown in Fig. 5.

Fig. 8 is a fragmentary sectional detail of the bristle and handle securing unit prior to fastening the elements thereof together as a. unit.

Referring to the drawings, A indicates a brush as a whole formed according to the present invention, which includes the bristles B carried in a bristle and handle securing unit C and a handle D.- The bristle and handle securing unit is comprised by a main ferrule I 0, a bristlesecuring element II, slidably fitting within the ferrule,

ment slidably fitting within the ferrule and cof operating with plastic material to retain the bristles solidly in position, a handle securing element slidably fitting within the ferrule and engaging the bristle securing element, and means in connection with the ferrule for jointly securing the ferrule, bristlesecuring member and handle securing element together. The handle securing element is specially formed to receive a handle without the necessity of nails, rivets or the like and is particularly adapted to secure a moulded plastic handle.

' securing element I3 may, when the element isv and a handle securing element I2'likewise slidably fitting within the ferrule.

The bristle securing element Il may take several forms, a known form of such element being illustrated in the present disclosure. This takes the form of a channel element having the base I3,

and continuous peripheral wall I 4, the base I3 be-v ing died to form the openings I5 and the angular projecting tongues or lugs iii, the terminals of which are bent to lie substantially parallel to the base I3. Theselatter portions of the tongues IB form the line of contact of the butt ends of the bristles whenthey are projected in normal po- The free extremities of the walls I4 of the securing element I3 are bent at right angles to form a, peripheral pro jecting flange IT. The ferrule at its normal upper'end is ofiset outwardly and enlarged as at I8 so that the peripheral flange I! of the bristle slidably projected into the ferrule Iii, be disposed 5 within the confine of the ferrule. The handle signed to, be slid into the enlarged end of the fer- The invention will be clearly understood by reference to the following detailed specification taken in conjunction with the accompanying drawings. p v

In the drawings,

Fig. 1 is a front elevation of a brush of the securing element I 2 is formed at its normally lower end with a peripheral flange I9 which is derule and into abutment with the flange of the bristle securing element.

the bristle securing element I3 and the handle rigid unit.

The handle securing element is likewise or.

Thus, by spinning or rolling the enlarged offset portion of the ferrule into engagement with the abutting flanges of' channel formation, being provided with the pe- 11 including a suitable spacer or wedge where de;-- sired, and the bristle securing element II is then projected into the open end of the ferrule until the faces of the tongues or lugs. 15, engage. the butts of the bristles B. A suitable cement is then poured into the open end of the ferrule so that it will pass through theopenings f5 and into the butts of the bristles, and, as indicated; at 25, will partially embedlthe bristle securing element. so. that the bristles. andsaid. latter element are firmly locked together.

The handle securing element. 1.2. may be. placed in. correlation to a suitable mould for forming a plastic handle. 'Thus, by employing a suitable stop plate positioned within. the handle receiving element which stops. the flow of; plastic. from, the mould at a predetermined; point, and. preferably coincid'ingwtih the base of the converging. ferrule 22 of said, element, the plastic material may be caused to enter this latter ferrule and when set is locked securely with the. handle receiving element. In this connection. the. handle is so moulded that .a peripheral. shoulder 22a. extends therefrom over the free; ends of ferrule 22, thus securing the handle from axial. movement in either direction.

It is but a simple operation to project. the handle receiving element with its attached handle into the open end of the ferrulev in until the flanges of the bristle securingel'ement and handle securing element are in abutment with one another, whereupon the enlarged portion. of the ferrule I0 is. suitably clinched, such as by spinning or rolling it around the dual projecting flanges l1 and [.9 formed respectively on these elements. In consequence, therefore, the three elements, namely, the. ferrule Ill, the. bristle securing element H, and the handle securing element l2, are lockedtogether as an inseparable rigid unit to produce a substantially unitary brush member which incorporates a solidly attached plastic handle. If. desired, of course, a

handle otherthan plastic might beemployed', but the former is desirable from several points of. view.

Alternatively, in securing the bristles within the ferrule Ill, thelatter may beslipped over the bristles and the flag end of the bristles may be dipped in a suitable adhesive which will temporarily set them. The ferrule may then be slipped down on the stiffened bristles and the then projecting butt ends of the bristles may be dipped in a suitable'cement up to a desired level. This methodprovides for a uniform infiltration encles in the usual type of ferrule, while also eliminating the necessity of nails, rivets, or the like for securing the handle. The elimination of nails or rivets produces an improvement in appearance which is an advantage. Of perhaps greater importance are two. further advantages. (in the one hand, nailsor rivets; as: in. the first instance, tend to make splits in the bristles resulting in a brush fingering during use. On the other hand, such nails or rivets are apt, in many v cases, to' cut the bristles off in the path of the rivets, thus weakening the setting and allowing the bristles to come out at such points. Likewise, the nailed. handles sometimes split as the W'nafls' are passed "through them, and serious disadvantages of this kind are completely eliminated according to the present invention.

Finally, several further. advantages are. produced. In one instance, thenecessity for a relatlvely deep. penetration of the bristle'butts into the. ferrule is eliminated as the. bristles may be set; firmly without the necessity'oi' deep penetration, and a suitable. overall depth forthe bris tle setting compound andwooden handle. This permits the use of shorter bristles obtained at a lower cost while maintaining a. fine quality of brush,. which is. of particular importance in the use. of nylonbristle. Moreover, the shortening-of. the. depth of the. ferrule permits the hand of the operator to. be nearer to the bristles, which is an important factor in keeping a. balance and in lessening the. leverage. that an operator has. to use in applyingpaintl It. also. provides for the useoflaplasticjhandle not possible. with the usual type offerrule construction, .and this although more. costly than wood offers certain offsetting,

advantages by the elimination of steps. of production. On the. one. hand the. plastic handlev comes fromthe moulds-with-a. very high finish and. with. the. trade. names and/or brand. names already on. it as produced by the mould, and in.

this manner without additional steps it is. possible to. produce. a hole in. the handle. for suspension. purposes when the brush is not in use, which is particularly necessary in. the case of. nylon bristles. which, if. leftto restupon the bottom of.

a container, under, the. weightof the. brush, will. bend andv cannot. be. straightened out. a ainhso.

that.- the. brushv therefore. ruined. The handle can also be produced in various. desirable colours. through moulding, with coloured. plastic material. In all, therefore the separate steps. of placing the: name on the brush. handle, theldipping. and dryingof the-.handlelands-theseparate nailingsstep are completely eliminated.

The sturdyconstruction. of bristleand. handle.

l securing unit. lends itself. to the use of nylon. bristle which ordinarily is harder to hold in setof cement since the cement will. naturally seek its own level in the dipping operation, and after this operation'hasbeen carried. out the ferrule is moved back to encase the butt end of the The bristle securing element ll may bristles. then be inserted and cementponred in the open end'of the ferrule to the desired-level.

The construction described provides avery" or rivets ofterr empioyed to offset bowing tendtingv than. ordinary bristles. The strong assembly of thissecuring unit produces .a. safety margin.-
