Definitions

  • a method of applying a protective coating to a surface under water which comprises forcing a protective coating composition through an applicator pad, for example using compreseed air, at a pressure at least equal to the ambient pressure of the water at the depth at which the coating is applied, and applying the coating composition to the surface by a smearing action of the pad.
  • Apparatus for carrying out the method includes a porous applicator pad, a reservoir for a protective coating composition to be supplied to the applicator pad, a sensing device for sensing the ambient water pressure, and a control device operative to maintain the pressure at which the composition is supplied to the applicator pad at least equal to the sensed pressure.
  • the applicator pad may be a layer of foamed "plastics material having an open interconnected cellular structure.
  • Paints are, however, available which are capable of setting to form an adherent coatinglunder water butdifficulty has been experienced in devising a satisfactory method of applying such paints to surfaces under water.
  • FIG. 3 is a sectional side view of the applicator shown in FIG. 2.
  • Theapparatus shown in FIG. 1 comprises an applicator 1 connected by a conduit 2 to a paint reservoir 3.
  • the paint reservoir 3 may be located on a quay or diving tender, but where the apparatus is portable, it is conveniently carried on the back of a diver. Paint is forced from the reservoir 3 to the applicator by means of compressed air which is fed along a conduit 4 from a control unit 5.
  • the control unit 5 is connected to a source of compressed air (not shown) by means of a conduit 6 having a suitable self-sealing adaptor 7.
  • the pressure in the compressed air conduit 4 is monitored by means of a gauge 8 which is connected to conduit 4 by means of an air line 9.
  • the gauge 8 is conveniently worn on the divers wrist.
  • each of the conduits 2, 4, 6 and 9 are constructed from a flexible material such as rubber or a thermoplastics material.
  • the air supply system also includes a pressbutton operated bleed valve 10 which can be operated .by the diver in order to releasepressure from the system and thus to stop the flow'of paint to the applicator.
  • Pressure in the system can be increased by operating a control valve 11 in the control unit 5. The effect of this is to increase the air pressure fed to the reservoir 3 and thus to increase the flow of paint to the applicator 1.
  • FIGS. 2 and 3 show the construction of the applicator l in more detail.
  • the applicator cornprises a housing member or body 20 formed from a corrosion resistant metal which is provided with a main longitudinal passage 21 for feeding paint to its lower surface.
  • a transverse passage 22 extends from a side wall of the body 20 and communicates with the end of the passage 21 remote from the lower surface of the body 20.
  • the passage 22 is appropriately sized to receive the constrictedend of a stainless steel tube 23 which is formed with an aperture 23a which coincides with the upper end of the passage 21.
  • the tube 23 is clamped into the body-20 by means of two bolts 24 and sealed intothe body by means of an epoxy resin glue.
  • Thetube 23 is conveniently provided with a handle 25 surface by a smearing action of the padi'Normally; the

  • sensing device for sensing the ambient water pressure
  • control device operative to maintain the pressure at which the paintissupplied to the applicator pad at least equal to the sensed pressure.
  • theporous pad is of flexible foamed plas-,
  • foam jplastics materials are polyether, polyester and polyurethane foams having open interconnected cellular structures. It has been (see FIG. 1) and atits free end with a pipeunion26 for connection to the rest of'the ap'paratus'As shown in FIG. 3, the lower face of the ll$ody20 is convexly curved and a layer 27'of flexible foamed plastics material having an open interconnected cellular structure is held in contact with the lower face of the body 20. Desirably, this foam layer is about 5 cms. thick and its flexibilityenables it to conform torthe shapeof the surface being painted and to exclude water from the interface.
  • a ring 28 of brassor other corrosion resistant metal serves to clamp'the pad comprising the foamed plastics layer 27,an'd a towelling outer cover 29 into found advantageous in practice to cover the free face of the plastics foam with a porous fabric and a particularly useful fabric has beenfoundto be a pile fabric contact with theib'ody Snap fasteners 30 (shown hold the ring 28 to the body 20.
  • the body 20 of the applicator, the tube 23 and the ring 28 may alternatively be manufactured from aplastics material, for example nylon, and in this case the tube 23 may be moulded inte grally with the body during manufacture.
  • air is fed along conduits 6 to the control unit 5 which includes means for sensing the ambient pressure at which the apparatus is used and is arranged to supply air along the conduit 4 at a pressure which is at least equal to the ambient pressure.
  • the apparatus in accordance with the invention it is possible to apply an anti-fouling paint to a thickness of 0.05 mm. in one pass of the applicator. Since there are no cocks, valves or other moving parts in contact with the paint the possibility of clogging is eliminated and cleaning and maintenance are facilitated.
  • the paint line can be cleaned by simply replac ing the reservoir 3 with a receptacle filled with a suitable paint solvent. By blowing the solvent through the conduit 2 and the applicator 1, the apparatus is effectively and conveniently cleaned.
  • the applicator 1 can be manipulated by hand, and the one illustrated is designed for such use. However, the applicator may also be manipulated by mechanical means. For example, an applicator may be mounted on an underwater vehicle and be driven so that it performs an orbital movement in contact with the surface to be painted. In a further development of the apparatus, the applicator may be arranged to travel on a magnetic track along the ships bottom or other steel surface and the operator cansimply follow the applicator and control its direction and the flow of paint to the applicator 4 pad.
  • Apparatus for applying paint to a surface under water comprising a porous applicator pad, a reservoir for paint, means for supplying paint under pressure from said reservoir to said pad, sensing means for sensing the ambient water pressure adjacent said pad and control means responsive to said pressure sensing means for regulating the pressure at which paint is supplied from said reservoir to said pad.
  • Apparatus according to claim 1 in which the applicator pad is a layer of foamed plastics material having an open interconnected cellular structure.
  • Apparatus according to claim 1 in which the pad is held between a retaining ring and a housing member, said housing member having a passage or passages for supplying the paint to the pad.
  • Apparatus according to claim 5 in which the housing member is connected to the reservoir, and the reservoir is connected by a supply line to a source of compressed air for forcing paint from the reservoir ot the applicator.
  • the supply line includes a normally-closed bleed valve which is adapted on operation to release compressed air from the supply line and thus to reduce the pressure in the supply line.
