Definitions

  • the invention relates to a spraying process, more particularly for colorsand its object is to prevent mist formation and loss of color.
  • Mist is formed by the air being cooled to such an extent that it is nolonger capable of retaining the water vapor dissolved in it, and causes the water vapor to separate out in the. form of
  • the cooling of .the air during spraying outer layers of the color-air do not travel asfar as the surface being sprayed, and secondly to the fact that particles of color-rebound from the surface being sprayed.
  • atomizer nozzle mounted round the atomizer nozzle is either a further annular nozzle or a plurality of individual nozzles which are arranged according to-the form of the color-air nozzle or the individual nozzles in thesame way as of the atomizer.
  • nozzle. is widened conically in the forward direction or the exit of the additional air is already effected in a direction correspending to the form of the color-air jet. Due
  • the atomizer nozzle is mounted in a receiving" nozzle widening conically in the forward direction and if desired other receiving nozzles are mounted around the first receiving nozzle, thereby securing the particular effect that the additional air and the outer air which it aspirates always flow along the inner walls of 10 the receiving nozzle, or that when working in the open, the wind does not blow away the color-. air Jet. I i
  • FIG. 1 A constructional example of the invention as applied .to an ordinary color spraying pistol is shown in the accompanying drawing in which Fig. 1 a longitudinal section of the device and Fig, 2 a section along line 2-! in Fig. 1.
  • A is the body of the device having a barrel shaped portion Band 9. grip-portionD.
  • a color supply conduit c and a conduit a for compressed air lead through the grip portion-D to'the front end of the barrel portion B.
  • the front end of the barrel portion is ,25
  • Nozzle bo'd'yE is provided with a flange o, and a nut P is screwed on the thread 1 of flange'i and engages the flange o, the reby securing the nozzle body E to the front of the barrel portion B of the pistol,
  • the nozzle body E has a tapering portion q with a 'number of external ribs r, and
  • a constricted front end a with the orifice t. 011- 4 flce t is controlled by a needle valve F which may be operated by any suitable means.
  • a cup-shaped member G having a conical inner surface fits on' ribs 1' of nozzle body E and is held the thread m of the flange k, and of a flange p provided on the outside of the cylindrical por- [tion u of member E. This member also su'rrounds'the front portion .9 of the color nozzle body'E at a suitable distance.
  • the bottom v of member- G is provided with apertures e arranged concentrical with the nozzle body E. and forming a substantially annular nozzle. ,On the front side of bottom 0, a-collar w is"- arranged, the peripheral surface of which tapers within the area confined by the annular nozzle or apertures e.
  • One or more conical receiving nozzles d, g and It may be attached to member G in any suitable manner, for instance by means of ribs :0, air being permitted to enter through the apertures at f, j'
  • the receiving nozzles d. a and h are helpful to prevent the envelope of compressed air from unduly spreading at its outside, and to keep the spray in its direction if the device is used in the open air in windy weather.
  • a sprayer particularly for colors. comprising an atomizer nozzle, at least one nozzle surrounding said atomizer nozzle and being adapted to emit compressed air, and a tubular member surrounding said air-emitting nozzle; both the outer surface of said atomizer nozzle and the inner surface of said tubular member being widened conically in the direction of spraying.
  • a sprayer particularly for colors, comprising an atomizer nozzle, at least one nozzle surrounding said atomizer nozzle and being adapted to emit compressed air, and a plurality of tubular members in staggeredarrangement inserted in,
  • a sprayer particularly for colors, comprising an atomizer nozzle, at least, one nozzle surrounding said atomizer nozzle and being adapted toremit compressed air, and a tubularmember 2,086,188 towards the bottom a and ends at the bottom surrounding said air-emitting nozzle at a distance, both the outer surface of said atomizer nozzle and the inner surface of said tubular member being widened conically in the direction of spraying, whereby the emitted compressed air may be guided along the widened surfaces and may take along atmospheric air entering into said tubular member throughthe space between said member and said air-emitting nozzle.
  • a sprayer particularly for colors, comprising an atomizer nozzlefor producing an outwardly diverging spray, and means surrounding said atomizer nozzle for developing an interiorly' diverging envelope of air enclosing the spray from the atomizer nozzle, said surrounding means including diverging means arranged interiorly with respect to said envelope for-directing its interior in substantially parallel relation to the shape of said spray.
  • a sprayer particularly for colors comprising an atomizer nozzle adapted to emit an exteriorly .diverging spray, and means concentrically surrounding said atomizer nozzle for emitting an enveloping and diverging jet of air, said means comprising outwardly diverging surfaces arranged interiorly with respect to said let for guiding it from its interior in substantially parallel relation to the outer surface of said spray.
  • a sprayer particularly for colors, comprising an atomizer nozzle for producing an outwardly diverging spray, and a nozzle surrounding said atomizer nozzle for emitting compressed air, said surrounding nozzle including a diverg ing surface for directing the interior of the emitted air Jet substantially in correspondence with the shape of the spray from said atomizer nozzle, said diyergingsurface being arrangedat the inside with respect to said air Jet and being sub-- stantially parallel with the outside of said spray.
