Definitions

  • This invention relates to improvements in brushes, and is particularly directed to improvements in brushes which can be used for painting.
  • Pig bristle is the preferred material for paint brushes, firstly, because it is resilient and springy in nature and has the ability to recover from deformation thus being resistant to taking a permanent "set".
  • each strand is of an extended conical or tapered 10. formation.
  • the root end is of larger diameter than the outer end which is referred to as the "flag" end because of the natural tendency for the outer end to split into several fine sections.
  • This quality is of value because the split or flag ends provide softness which can apply paint without leaving brush marks. These is. qualities render pig bristle as an ideal material for use in the manufacture of paint brushes.
  • the usual method of paint brush manufacture comprises the selection of a tuft or bundle of bristle of the desired size or volume and of the desired length. This bundle is then positioned within a
  • metal furrule of desired dimension and shape usually of an elongated rectangle.
  • the root ends of the bristles are placed within the ferrule to a depth of approximately half an inch.
  • Suitable cement usually a synthetic resin of the epoxy type, is poured onto the inverted root ends of the bristle and allowed to
  • level fibre or synthetic monofilament i.e., material of constant diameter from which the tapered or 10. elongate conical shape is absent.
  • level monofilament is considerably less than that of monofilament of tapered configuration.
  • One object of this invention is to provide an improved paint brush which can make use of parallel fibres or monofilaments formed from a polymeric
  • This invention is characterized by a brush having a plurality of 30. apertures arranged in at least two rows, the apertures being inclined with respect to one another in such a way that when containing filaments, the filaments will come together at a locality which is external of the brush handle but between the handle and the tips of the fibres.
  • the invention has a number of advantages. Since the fibres can be formed from synthetic resin monofilaments of constant cross-
  • the paint brush can be produced relatively inexpensively, and the fibres of the two rows in being inclined to one another, will work as the brush is moved in use to move the paint towards the tip and will provide a brush producing a finish similar to that of a paint brush made by conventional methods and
  • FIG. 1 is an end view of a brush according to the invention, is.
  • FIG. 2 is an exploded view of the brush, and
  • FIG. 3 is a cross-sectional view along the lines 3-3 of FIG. 2.
  • the essential feature of the invention resides in the inclination of the two rows of tufts of filaments to slope towards each other, the 20. filaments being inserted into two rows of apertures whose axes of each row are inclined toward each other.
  • the apertures can be formed in the base of the brush, for example by drilling, or by moulding during the production of the handle and base. Drilling would require a number of operations, and the 25. moulding while possible would be difficult due to the fact that the two rows of apertures are inclined towards each other.
  • the brush 1 comprises a handle joining to a base 2 having an upstanding flange 3.
  • a pair of blocks 4 having apertures 5 into which the tufts 6 of filament 7 are supported by and attached to the flange 3 and base 2.
  • each of the blocks 4 is generally triangular in end view, the sides 8 sloping towards each other at an included angle of between 10 degrees to 15 degrees, preferably 12 degrees.
  • Each of the blocks 4, only one of which will be described for clarity, has an inner side surface 9, the centre line of the apertures 5 being generally parallel to the inner lo. side surface 9.
  • the flange 3 and the inner side surface 9 do not extend the length of the base 2, and the inner side surface 9 r when the brush is assembled, engages the side 8 of the flange, the ends of the blocks 4 having a portion 10 to extend past the end of the flange 3 and engage a further portion 10 of the is. other block, the engaging faces 11 thus being on the centre line of the brush 1.
  • a row or rows of apertures 5 Into the block 4 there are formed a row or rows of apertures 5, these being at an angle to the vertical faces 11 , and tufts of filaments 12 are inserted into the apertures, these tufts are formed 20. by folding a bunch of filaments over and stapling with a staple 13 into the base of the block.
  • the flange 3 has one or more pegs 14 extending from both surfaces 8, these being adapted to engage in holes 15 in the inner side surface 9 of each block so that the blocks with the tufts 25. of filaments are merely clipped to the flange 3.
  • the filaments are formed of a plurality of monofilaments of suitable polymeric material, such as polyester. Other fibres may 30. be used, each of the filaments being parallel throughout their length and therefore are produced by a simple extrusion process.
  • the parts can be identical, and therefore only one set of tooling is required for their production. There is an avoidance of converging aperture surfaces, such that use of complex dies for ejection purposes is unnecessary. Because of the art which is presently known, the filling, tapering and trimming of the filament ends can be effected automatically or semi-automatically.

Abstract

Un pinceau (1) comprend des touffes de monofilaments (7) de section transversale constante sur toute leur longueur. Les touffes de monofilaments sont disposés dans deux rangées d'ouvertures (5) ménagées dans des blocs (4). Les rangées d'ouvertures sont inclinées les unes vers les autres, ce qui permet aux rangées de monofilaments de se rejoindre à l'extrémité du pinceau.
