  • Fig. 7 is a diagrammatic showing of a further form of a paint applying apparatus designed in accordance with the invention.
  • Fig. 1 it will be seen that they liquidw paint Il under pressure flows into a container 4 through a flexible pipe 2 provided with at stop or regulation valve 3r that may be adapted to, serve asv a control-handle.
  • a vertical spreader 6 is inserted intoV theA bottom ofv the container 4.
  • the lower end 1 of the spreader 6 projecting; from the container 4 is halfcylindrcal in shape; it is intended to be applied against they surface under treatment 8 for the purpose. to appli,1 to this surface a priming film oit paint 9, the latterbeing formed when ther apparatus, is; advanced.v in the direction.
  • the width of the two films may be controlled by providing the spaces I2 and I5 with suitable end Walls (not shown.) parallel to the plane of the paper, or by the factors influencing the ow of the liquid paint through the said spaces, such as the number and sizesof holes II and I4 and the location, nature and elasticity of the blades I3 and I6.
  • this apparatus is as follows: The apparatus being displaced in the direction of the arrow I9 and its spreader 6 being applied against the surface 8, the liquid paint iiowing down from the space I2 against the spreader 6 is laminated between the spreader surface 'I and the surface 8, the air or other ambient medium being expelled forward, so that the adherence of the priming film 9 to its support is fully assured.
  • the elastic deformation of the spreader end 'I enables application ofv the paint even onto projections from the surface 8, such as rivet heads or variations in normal thicknesses. Since the space I5 is i'llled with liquid paint, the entrance of air or of anotherfambient medium is prevented and the iinal layer of paint takes the form of a film I8, incorporating the priming lm 9, the total thickness ofwhich is regulated by the distance between the edge I1 of resilient blade I6 and the surface 8.
  • the deformationk of theblade I6, particularly near its edge I'I, is such as to per- :pose itself between the two films.
  • spreader 6 has a cylindrical shape and is inserted into a cylindrically shaped housing welded at -2I to the container 4 composed of two cylindrical parts 22 and 23, with their axes respectively parallel and perpendicular to the surface 8 to be painted.
  • the resilient blades I3 and I6 are aixed, by means of screws such as 25, to the cylinder 22 having its ends closed by means of walls 24.
  • the holes II and I4 are conveniently spaced along the cylinder 22 and adapted to direct the liquid paint I to the spaces I2 and I5, respectively, and therefrom along the spreader at 3
  • a valve disc 33 is mounted on the central extension 34 of a bar 35 diametrally affixed to the cylinder 22 by means of screws 25.
  • the seat for this valve disc is disposed upon the bottom 3l of a cylindrical part 38 topped by a part 39 screwed thereon as at 4I.
  • valve disc 33 is centered by means of ribs 43 and its stroke, with respect to the seat 36, is
  • abutment 45 adapted to act upon the upper end of the valve rod 44.
  • the part 39 is pierced with liquid paint feed openings 46 and has its upper portion threaded as at 41 to receive a fitting 48 (Fig. 2) adapted for connection with the corresponding end of a flexible pipe (not shown) intended to supply the apparatus with liquid paint under pressure from a feed tank not shown.
  • the cylindric part is slidably guided by ribs 49 arranged in the cylinder 23.
  • a screw-threaded collar 5I and a U-shaped annular leather packing 52 provide a tight joint for the passage of the cylindrical part 38 outside of the ribs 49, the part 38 being prevented from rotation by means of lugs 53 (Fig. 2) rigidly connected with the cylinder 23.
  • the liquid paint passes into the cylinder 22 and, through the holes II and I4, into the spaces I2 and I5.
  • the spreader 6' causes the priming lm 9 to adhere to the surface 8, while the edge II causes a second lm to immediately coat the priming film 9, whereby a compound layer of paint I8 is produced whose thickness E is regulated by the edge il, without the air or other medium being adapted to inter- In this way perfect coating is obtained by a single passage of the apparatus.
  • the liquid paint under pressure may be fed into the apparatus with the aid of any suitable outside feeding means.
  • Such an apparatus is particularly suitable for painting large surfaces or for an extensive serial work.
  • FIG. 4 Shown in Fig. 4 is a form of painting apparatusin which a limited quantity of liquid paint is con* ned alone in the container 4 which here is cylindro-spherical in shape, the cylinder 6I being open at its top so as to receive a corresponding cylindro-spherical piston 62 directed by outside guides 63 and tightened by a packing ring 64.
  • the lower half-sphere 65 carries,as in Fig. 2, the spreader 6' and two resilient blades I3, I6.
  • the spreader 6 is inserted into the housing 5 having a length corresponding to that of the blades I3, I6.
  • rI'he bottom 65 of container 4 has paint outlets I I, I4 and may be provided with a filtering wirescreen 66.
  • the pressure exerted by the operator causes the spreader 6 to press against the surface 8; at the same time the apparatus is displaced by the operator in the direction of the arrow I9.
  • Fig. 5 Diagrammatically shown in Fig. 5 is a cylindrical form of spreader for use in painting apparatus, such for example as those shown in Figs. 2, 3 and 4.
  • the spreader has the shape of a thick plate 1I, made for example from soft porous rubber, disposed around a suitable core 'I0 and pasted onto the inner surface of the cylindrically shaped housing 5.
  • a spreader of this kind may be mounted on bearings so as to rotate when spreading the priming lm.
  • the experience however, teaches that the rotating spreaders, when passing over rivets and the like, are actually caused to rotate. So use will be made, preferably, of non-rotating spreader members like those described hereinabove.
  • Fig. 6 An advantageous form of spreader is shown in Fig. 6. I-Iere the spreader has again the form of a thick plate 'II' which is made from elastic and deformable material, such as soft porous rubber, but is U-shaped and confined in a parallelopipedlike housing 12 carried by the container 4.
  • a thick plate 'II' which is made from elastic and deformable material, such as soft porous rubber, but is U-shaped and confined in a parallelopipedlike housing 12 carried by the container 4.
  • the outer wall of the rubber 'I I is provided with a lining diagrammatically indicated by a dotted line 13 in the drawing, said lining being tted into the housing 72.
  • This lining may be made from any suitable iiexible material of convenient thickness, such as nylon or other plastic material. Of course, this material should have the requisite mechanical qualities at points of its contact with the coating materials applied by the apparatus.
  • Fig. '7 Diagrammatically shown in Fig. '7 is a form of painting apparatus in which two dierent coating materials are used, namely an adhesive and a paint, for example.
  • the container 4 is divided by a center partition 82 into two compartments 83 and 84. Each of these compartments is pressure-supplied with a coating liquid supplied through the feed pipes 85, 86.
  • a unidirectionally traveling device for the successive spreading of superposed coatings to a surface comprising a ⁇ container for the accom-- modation of at least one coating liquid, at least The operation of this apparatus is analogous to the one described above, the liquid one tube attached to said container for the pressure supply of said coating liquid into the container, a resiliently deformable spreader for the distribution or ⁇ two successive layers of said coating liquid to cover said surface, said spreader being ixedly located in the center portion of the container bottom and downwardly projecting from the same, openings in the bottom of said container for the downward passage of the coating liquid simultaneously onto the advance and the opposite rear face of said spreader, resilient guide blades fastened to the bottom portion of said container and downwardly projecting from the same towards the surface to be covered in order to direct said coating liquid onto the latter, said guide blades forming an advance blade and a rear blade and being located in front of the advance face and in the rear of the opposite rear face of said spreader being bent with their ends towards the saine and orrning there
  • a unidirectionally traveling device according to claim 1 wherein the advance blade is shorter than the rear blade.
  • a vertical wall in said container to divide the same into adjacent advance and rear compartments and supply tubes for the coating liquids attached to each compartment.
