Definitions

  • the second hollow element has a transverse plate at its outer end and said plate is formed with a series of openings and, outwardly of the openings, somewhat L-shaped lugs with the outer ends thereof substantially parallel to the transverse plate.
  • This construction is somewhat complex in that there are four parts other than the bristles and the cement, and such parts have to be assembled, the first hollow member has to be secured to the handle.
  • Maxwell in his US. Patent No. 2,840,841, discloses the bonding of a transverse retaining element in the adhesive which fastens the bristles to a ferrule, the retaining element being keyed in a slot provided at the end of a wooden handle and the ferrule being fastened to the handle by nails in previously conventional manner. This also requires the use of fastening nails, the handle is This 3,231,920 Patented Feb. 1, 1966 of wood and of solid construction, and the slot for attachment of the retaining element requires special machining.
  • An important object of this invention is to provide a paint brush of relatively simple design and construction which will be relatively economical to manufacture in large quantities by mass-production techniques, of extremely pleasant appearance and which will provide for a very good and 'eflicient connection of the bristles to the handle.
  • the handle member is formed with a plug-like part at its front end-the end to which the bristles are attachedand that part is adapted to fit in the ferrule.
  • locking members such as flanges or lugs which extend angularly in relation to the longitudinal centre line of the handle member in such manner that when the plug-like part is engaged in the ferrule, and the locking members project into an adhesive mass in the ferrule, there is effected an interlocking engagement between the locking members and that adhesive mass to fasten the ferrule to the handle member.
  • the plug-like member comprises an upstanding wall having inwardly directed flanges at spaced intervals around its periphery. It is also preferred that the ferrule be provided with an inturned flange at its front end, providing a mouth at the front of the ferrule of smaller area than the remainder of the ferrule, and that the front inner edge of that flange be chamfered to provide a seating for a quantity of adhesive about the outer side of the knot of bristles,
  • FIG. 1 is a perspective view of the paint brush
  • FIG. 2 shows a perspective view, from the front, of the handle member of the paint brush
  • FIG. 3 is a front elevation of the handle member
  • FIG. 4 shows a longitudinal cross-section through the ferrule of the paint brush
  • FIG. 5 shows a longitudinal cross-section through the ferrule with a bristle knot positioned therein and secured in position by application of an adhesive
  • FIG. 6 is a longitudinal cross-section similar to FIG. 5 but showing, also, the handle member engaged in the ferrule;
  • FIG. 7 is a detail view on enlarged scale of the part indicated by the circle referenced 7 in FIG. 6.
  • the paint brush illustrated in these drawings consists of a handle member 11, a ferrule 12, bristles 13 and adhesive securing the bristles 13 in the ferrule 12 and securing the ferrule 12 and bristles 13 to the handle member 11, such adhesive being indicated by the references 14, 15 and 16.
  • the handle member 11 is of hollow construction and it is made of nylon, or other suitable plastic material, and it may be made by injection moulding, blow-moulding or slush moulding operations.
  • the handle itself, indicated by the reference 17, is of a suitable shape to provide for a comfortable grip and at the front of the handle 17 is an external flange 18 of substantially rectangular shape but having rounded corners and slightly curved ends.
  • a socket 9 In the front surface of that flange is a groove or recess 19 and forwardly of the flange is a socket 9 having a base 10 and a side wall 20 of rectangular shape internally and substantially rectangular externally, the external surface of said wall having rounded corners and ends which are slightly curved-that is to say, arcuate but with a relatively lar-ge radius of curvaturesubstantially the same as the flange 18.
  • the wall 20 extends in the same direction as the longitudinal axis of the handle member.
  • a lug 21 which projects inwardly substantially perpendicular to the longitudinal axis of the handle member, each extending approximately one-quarter way across the open mouth of the handle member 11 and each being approximately one-half the length of that open mouth.
  • Each of the opposite ends of the wall 20 extends a small distance longitudinally beyond the two sides and at about the middle of each end is a lug 22 which projects inwardly about the same distance as the lugs 21.
  • Each of the lugs 22 is approximately half the width of the open mouth of the handle member. These latter lugs 22 extend from recesses 23 in the front surfaces of the opposite ends of the wall 20.
  • the lugs 21 and 22 are conveniently formed by first forming them as longitudinal extensions of the sides and ends of the wall 20, the lugs 21 extending in the same planes as the opposite sides and the lugs 22 extending in the same planes as the opposite ends of the wall 20, and then, by applying heat and pressure to said lugs, bending them inwards to the positions as illustrated particularly in FIGS. 2 and 3.
  • the ferrule 12 is made the same shape as the external surface of the wall 20 and is a neat sliding fit thereon, the length of the ferrule 12 being somewhat greater than the height of the wall 20as about A".
  • the ferrule is also rnade of nylon, or other suitable plastic material, and the thickness of the material at the rear end is slightly less than the width of the groove 19 in the flange 18 so that the rear edge portion of the ferrule 12 can fit neatly in that groove.
  • the handle member 11 and the ferrule 12 should be made of such materials that they may be fastened together adhesively-nylon, as previously mentioned, or polypropyleneand they may be made any suitable colours to provide an attractive appearance-preferably different colours to provide a contrast.
  • the opposite sides of the wall 20 may be made so that they are very slightly concave, a small amount closer together at their middle points than at their opposite ends.
  • the bristles, 13, are fitted into the ferrule 12 in known manner so that the rear ends thereof are gripped within the inturned ledge or flange 24, and then a quantity of adhesive, 14, is fed into the ferrule 12 so as to cover the inner or rear ends of the bristles and penetrate into the bristles to securely bond them in position, as shown in FIG. 5.
  • the quantity of adhesive used is such that a small amount of the adhesive will penetrate the bristles past the inturned lip or flange and flow into the recess provided by the chamfer 25such adhesive being indicated by the reference 15.
  • a suitable adhesive is an epoxy or polyester resin.
  • That adhesive has set there is, in effect, a substantially rigid block of adhesive extending across the inside of the ferrule from end to end and from side to side, and adhering to the inner surface of the ferrule as well as to the bristles. That block of adhesive is larger than the opening at the front of the ferrule, due to the inturned ledge or flange 24. Thus, the bristles cannot be pulled forwardly out of the ferrule. Also, as the adhesive extends into the recess provided by the chamfer 25 the bristles and adhesive are locked in position relative to the ferrule so that the ferrule cannot be pulled forwardly relative to the bristles. It will be appreciated that the depth of the layer of adhesive, 14 should be such that it will not prevent full engagement of the wall 20 and lugs 21, 22 in the ferrule, and it should fully cover the ends of the bristles 13.
  • a small quantity of the same adhesive, 15 is then fed into the space provided around the outside of the bristles 13, within the chamfered part 25 at the front inner edge of the lip or flange 24, so as to lock the bristles 13 in position.
  • the layer of adhesive 15 may consist of seepage of adhesive from the quantity placed within the ferrule, or it may be a separately-applied quantity of adhesive.
  • a further quantity of the adhesive, 16 is placed within the ferrule to a depth such that when the handle member is engaged with the ferrule, as is next done-as shown in FIG. 6 by inserting the wall 20 into the ferrule 12, then the inturned lugs 21, 22 will be covered by that adhesive, as shown particularly in FIG. 7. Accordingly a first continuous substantially rectangular zone of adhesive is interposed between the ends of the bristles 13 and the lugs 21, 22 and extends laterally outwardly of the bristles adjacent their bound ends and a second continuous substantially rectangular zone of adhesive interposed between the lugs and the socket base having a major portion integral with the first zone.
  • a film of adhesive be placed in the groove 19 and/or upon the rear edge of the ferrule 12 so that when the rear edge of the ferrule 12 is engaged in that groove there will be effected an adhesive bond between the parts at that location.
  • the steps of assembly of the parts of the paint brush described above include two applications of adhesive to the interior of the ferrule 12 the assembly may be carried out by using one application of adhesive to the interior of the ferrule.
  • adhesive to the interior of the ferrule.
  • sufiicient quantity of adhesive may be applied to the interior of the ferrule a sufiicient quantity of adhesive to ensure the interlocking engagement of the lugs 21 and 22 in the adhesive mass as well as the bonding of the bristles 13 in the ferrule 12.
  • each of the sides and ends of the wall 20 there may be provided a series of spaced lugs along each of the sides and/or ends, and they may be made of such length that when they are turned inwardly their inner corners are close together.
  • brushesas 4" to 6" brushesthere may be provided, within the wall 20, two ribs or webs on opposite sides of the throat of the handle and extending between the sides, and these may be provided with outturned lugs at their front ends, said lugs being in the same plane as the lugs 22.
  • a paint brush comprising in combination a hollow, one-piece, handle molded of relatively lightweight material having an elongated hand grip portion and terminating in an outwardly disposed substantially rectangular socket, said socket including a base integral with said grip portion and having opposed parallel endwalls and opposed parallel sidewalls extending outwardly from said base and terminating in an outer free end portion, a laterally outwardly extending flange surrounding said base of said socket, a plurality of individual laterally extending adhesive engaging surfaces spaced about the outer free end portion of said rectangular socket, bristles adhesively bound together adjacent one end in an adhesive mass extending outwardly of said handle, said adhesive mass securing said bound end of said bristles directly to said socket with 'said adhesive engaging surfaces embedded in said adhesive mass, a substantially rectangular ferrule formed with an opening therethrough having opposed parallel endwalls and opposed parallel sidewalls tightly engaged about said respective endwalls and sidewalls of said socket, said ferrule extending outwardly of said adhesive engaging surfaces and formed at its outermost end with an inturned lip
  • a paint brush comprising in combination a hollow, one-piece, handle molded of relatively lightweight material having an elongated hand grip portion and terminating in an outwardly disposed substantially rectangular socket, said socket including a base integral with said grip portion and having opposed parallel endwalls and 0pposed parallel sidewalls extending outwardly from said base and terminating in an outer free end portion, a laterally outwardly extending flange surrounding said base of said socket, a plurality of individual laterally extending adhesive engaging lugs spaced about the outer free edge of said socket extending angularly inwardly therefrom so as to partially close off the outer open end of said socket,
