Definitions

  • a peripheral array of relatively hard bristles may receive another reagent, lvent from a se arate com artment of the [56] References Cited e a so p p brush body wh1le an inner core of harder bristles 15 UNITED STATES PATENTS Supplied with paint.
  • This invention relates to a device for applying a protective coating to an immerged surface.
  • a device for applying a protective coating to an immerged surface at least one rotary brush whose body has a chamber connected to a source of coating material under pressure, this chamber communicating through at least one flexible outlet tube with a set of bristles carried on the brush body.
  • the outlet tube or tubes terminate just short of the tips of the bristles which are relatively hard in a central zone and relatively soft in a surrounding peripheral zone, the two zones being centered on the axis of rotation of the brush body whose bristle-studded lower surface is perpendicular to that axis.
  • FIG. 1 is a schematic view, partly in section, of the first embodiment
  • FIG. 2 is a schematic view as in FIG. 1, showing the second embodiment
  • FIG. 3 is an explanatory diagram
  • FIGS. 4 and 5 are sectional views of the third embodiment, showing it in the operative and in the inoperative position, respectively.
  • a paint container is indicated by R and has an outlet connected by a pipe C, to a pump P communicating through a pipe C, and a passage C, with a chamber E provided in the interior of a casing B, the passage C*, extending through a lid B, of the casing B.
  • the bottom of the casing B supports on its outside a bunch of bristles F whereas the lid B of the casing B is secured to a plate G firmly connected to the drive shaft of a drive motor M.
  • the pipe C Before reaching the chamber E the pipe C, extends through the housing and drive shaft of the motor M which is arranged coaxially to the passage C*, leading to the interior of the chamber E.
  • the motor M and the casing B are immerged in the liquid L which may be, for example, salt or fresh water.
  • the end of the bunch of bristles F is in contact with a surface S to be painted.
  • the container R and the pump P may be kept out of the liquid L and may preferably be mounted on a ship (not shown).
  • the hardness p of the bunch of bristles F is indicated on the ordinate and the diametrical dimension D of the bunch of bristles on the abscissa.
  • the curve 5 shows that the bristles in the zone Z, of the bunch of bristles F are harder than in the crown of bristles Z Z' surrounding the central zone 2,.
  • a plurality of tubular elements 2,, t t, are arranged in the interior of the bunch of bristles F in the central zone Z and connect the chamber E with the liquid L which is in direct contact with the surface S to be painted.
  • the two zones of bristles forming the bunch F are designed so as to perform two complementary functions.
  • the zone of hard bristles Z, which receives the paint is designed to penetrate the boundary layer between the water and the surface to be painted to ensure good adhesion of the paint whereas the crown of soft bristles Z Z is designed to smooth the paint.
  • the container R is filled with paint having one or more components, particularly designed for application under water, such as the paints mentioned above.
  • a paint with several components it is necessary to provide a dosing and mixing unit (not shown) at the outlet of each container R containing the components.
  • the assembly to be immerged formed by the casing B supporting on one side the bunch of bristles P and on the other side the drive motor M is carried to the surface to be coated to assume the position illustrated in FIG. 1.
  • the pump P and the motor M are started simultaneously so that the paint will flow from the container R to the chamber E while the casing B is rotatively driven.
  • the pressure exerted by the pump P causes the paint to be discharged through the tubular elements 1,, t t,, which are firmly secured to the chamber E and therefore will rotate together with the bunch of bristles F.
  • the tubular elements terminate in the zone of the bunch F where the bristles are harder and as the bristles are rotating, the boundary layer of the water is penetrated in a circular area of the surface S which is in contact with the central zone Z, of the bunch of bristles F so that the paint leaving the tubular elements t,, t will be spread in this zone on the surface to be painted without leaving water drops enclosed between this surface and the paint, which would be prejudicial to the adhesion of the paint.
  • the brush As the paint is leaving the tubular elements t,, t t the brush is moved laterally so that the bunch of bristles F is shifted while remaining in close contact with the surface S. Thereby the softer outer bristles of the peripheral crown Z Z' surrounding the zone Z, rub the layer of paint which has been spread by the harder inner bristles. By the rubbing of the softer bristles the paint is smoothed which is particularly important if the surface to be painted is the hull of a ship.
  • the second embodiment shown in FIG. 2 differs from the embodiment of FIG. 1 only in that it permits to add another reagent to the paint composition applied to surface S, namely a supplementary solvent or, in the case of a paint having several components, a reaction retarder designed to check the hardening of the two mixed components.
  • This solvent or retarder is fed up to the immediate vicinity of the surface S in the peripheral zone of the bunch of bristles F,.
  • a first container R for the paint has an outlet connected through a pipe C to the inlet of a pump P
  • the outlet of the pump P communicates through a pipe C, and a passage C* with a chamber E, in the interior of a cylindrical casing B,, the passage C, extending through a lid B, of the casing B,.
  • the bottom of the casing B supports on its outside a bunch of bristles F, whereas the lid B, of the casing B, is secured to a plate G, firmly connected to the drive shaft ofa drive motor M,.
  • a second container R serves to receive the solvent or reaction retarder and has an outlet connected through a pipe C to the inlet of a pump P,.
  • the outlet of the pump P communicates through conduits C';,, C*,, and C, with an annular chamber or compartment E provided in the casing B, around the chamber E,.
  • the pipe C* extends laterally from the drive shaft of the motor M, to the passage C which traverses the lid B', of the casing B, and opens into the annular chamber [5,.
  • composition of the bunch of bristles F is the same as that of the bunch of bristles F.
  • tubular elements t*, to t*, supply a solvent whereas the paint is supplied by the tubular elements I, to r,,.
  • a plurality of the described devices may be mounted on a common support so as to form a battery of rotary brushes.
  • the device according to the invention is particularly suitable for overhauling a ship it can obviously also be used for coating any other immerged surfaces such as the piers of bridges, gates of dams, submarine pipes and the like.
  • the crown of softer bristles may be mounted on a support rotatable around the casing B, for example, by means of a ball bearing.
  • the crown of softer bristles may rotate in a direction opposite to that of the casing B so as to produce a relative movement between the two zones of bristles.
  • the bunch of bristles of the brush comprises a central zone of hard bristles F surrounded by a crown of softer bristles F which have free ends extending in the inoperative position beyond the free ends of the hard bristles; see FIG. 5.
  • the greater length of the softer bristles permits them to bend until they are flush with the ends of the hard bristles F when the brush is applied to a surface S to be painted, as shown in FIG. 4.
  • the bending of the softer bristles F helps smooth the layer of paint applied to the surface S as the boundary layer of the liquid is penetrated by the hard bristles F in the central zone of the bunch of bristles.
  • This form of construction may obviously be applied both to the embodiment of FIG. 1 and to the embodiment of FIG. 2.
  • the flexibility of the tubular elements 1,, t t,,, t',, t' t',, and t", 1",, serving as outlets for the coating material is substantially the same as that of the bunch of bristles in which they are arranged so that during application of the paint they will behave substantially in the same manner as the bristles.
  • the free ends of the tubular outlet elements are somewhat withdrawn relative to the free ends of the adjacent bristles so that the bristles can slightly bend before these tubular elements contact the surface to be painted.
  • said drive means comprises a motor having a shaft, said source communicating with said chamber through said shaft.
