Abstract
Abstract An apparatus for producing a uniform film of a coating liquid on a surface of a glass article, especially on a surface of a flat sheet or plate glass, in which the coating liquid is maintained in the form of a meniscus between the glass surface and a rodshaped coating element so that the meniscus moves along the glass surface to produce the desired film thereon. The rod-shaped coating element is disposed at a small distance from the glass surface and is so arranged that the coating element be moved relatively to and in parallel with said surface. The coating liquid is, for example, a solution of metal compounds, and the film so produced is then dried and fired.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
76 words
An apparatus according to claim 1, said drive means comprising a flexible elongated element one end of which is secured to said carriage and a reel for winding up the other end of the elongated element, and a drive mechanism for rotating the reel, the elongated element extending in the direction of travel of the carriage for causing the carriage to slide along the track means as the elongated element is wound up on the reel.
Claim 2
Dependent Claim
51 words
An apparatus according to claim 2, wherein a second flexible elongated element is attached to said carriage, said second flexible elongated element extending in the opposite direction with respect to the direction of travel of said carriage, and a weight is attached to the free end of the second elongated element.
Claim 3
Dependent Claim
37 words
An apparatus according to claim 1, wherein the track means are grooved tracks, a guide rail is disposed in each track and engaged by said sliding pieces, and a lubricating oil is maintained in said grooved tracks.
Claim 4
Dependent Claim
92 words
An apparatus according to claim 1, wherein the coating element is mounted on a shaft, and the means for vertically moving the coating element comprises shaft bearings, A support plate for each of said shaft bearings a rotatable feed screw extending through a threaded hole in each support plate, guide shafts extending through holes in each guiding plate on both sides of the threaded hole thereof and parallel to said feed screw, and means for rotating the feed screw, thereby raising or lowering the support plate and the coating element connected thereto.
Claim 5
Dependent Claim
140 words
An apparatus according to claim 1, additionally including a means for moving the coating element transversly to the movement of the carriage, comprising a control plate extending laterally of said carriage and parallel thereto, the control plate being fixedly secured to said carriage and having a camming edge extending obliquely to the lateral edge of the carriage, a rotatable guide pin attached to the coating element and adapted to engage with the camming edge of said control plate, a flexible elongated element fixedly secured to said coating element, and a weight attached to the free end of said elongated element, said elongated element being adapted to pull the coating element transversely with respect to the path of travel of said carriage whereby the coating element is moved transversely according to the contour of said camming edge while the carriage slides.
