Definitions

  • My invention relates to improvements in coated glass plates, such as silver-coated glass plates used in the manufacture of mirrors.
  • the coating is provided with a protective layer consisting of lacquer or the like.
  • the object of the improvements is to provide a coated glass plate in which the destruction of the coating caused by atmospheric influences and humidw ity deposited thereon and by expansion of the coating by heat is avoided, and with this object in view my invention consists in providing the glass plate at the coated side thereof with a bezeled margin extending from the coated face to the circumferential margin thereof, the coating of the face of the plate extending to the said bezeled margin, and the protective layer or the like extending on the bezeled margin.
  • a protective layer consisting of lacquer or the like
  • the bezeled margin is roughened by suitable means so that the protective layer firmly sticks thereto.
  • Fig. 1' is a sectional elevation showing the bottom part of a silver-coated glass plate of the construction now in use, and
  • Fig. 2 is a similar sectional elevation showing my improved glass plate.
  • a silver-coated glass plate as now manufactured consists of a plate 1, a silver-coating 2 applied to the 7 rear face of the glass plate, and a protective *9 layer 3 applied to the rear face of the silvercoating. As shown in Fig. 1, both coatings extend to the outer margin of the plate.
  • my improved silver-coated glass plate consists of a plate l having at its rear side a bezeled margin 5, U
  • the protective layer sticks to the bezeled margin of the glass plate, and it encloses the silver-coating 6 not only at the rear face thereof, but also at the margin thereof.
  • the bezeled margin 5 is made rough by suitable means, so that the protective layer firmly sticks thereto.
  • any humidity deposited on the rear face of the mirror and flowing downwardly thereon is collected at the lower margin of the bezeled portion 5 where it has no access to the silver-coating, and it does not pass between the protective layer 5 and the glass plate, the said protective layer being firmly united with the glass plate. If by mechanical influences the protective layer of the bezeled margin 5 is injured, the silvercoating is not exposed, because it extends only to a part away from the outer margin of the glass plate, where it is not subjected to mechanical injury. Further, the protective layer sticking to the bezeled margin 5 prevents loosening of the silver-coating from the glass plate in case of nonuniform expansion by heat of the coating and the layer.
  • a glass body comprising a body having a rear face and a bezeled marginal edge bounding said rear face, a coating covering the rear face up to the line of intersection of said rear face and said bezeled marginal edge, and a protective layer covering the outer surface of said coating and extending beyond the latter into adhering contact with the bezeled marginal edge.
  • a glass plate comprising a body having a plane rear face and a bezeled marginal edge having a roughened surface bounding said plane rear face, a metallic coating covering the plane rear face up to the line of intel-section of said plane rear face and said bczeled marginal edge, and a protective layer covering the outer surface of said coatlng and extending beyond the latter to and covering the roughened surface of said bezeled marginal edge.
