Delaware to The Frink Corpora- N. Y., a corporation of Application January 29, 1936, Serial No. 61,258
9 Claims.
The present invention relates to the manufacture of sign plates and like ornamental panels and more especially contemplates an improved method for making devices of the character shown, described and claimed in our copending application Serial No. 11,222 which was filed in the U. S. Patent Ofiice under date of March 15, 1935. The drawings of our above-identified copending application show an integral plate of light-transmitting material such as plate glass with lens-like portions left by an excavating operation forming characters in relief protruding from an opaque background preferably formed by an electroplating operation on a depressed background left by a sand-blasting operation. The sign plate shown on the drawings of said application produces striking effects on the eye of a distant observer due to the polished transparent top surfaces and translucent sides of the 1ens-like letters which stand out in bold illuminated relief on a non-luminous background of subdued tone.
The general purpose of our invention is to provide an improved method for making ornamental panels such as the plate glass sign shown and described in our above-identified application.
One purpose of our invention is to provide an improved method whereby sign plates of somewhat similar character to that shown in U. S. Patent No. 1,525,107 to W. H. Spencer, may be rendered more discernible and ornamentally pleasing to the eye of a distant observer. According to this Spencer patent, the letters of the sign plate were formed by residual portions of the original surface of the plate glass remaining after intervening areas of the surface had been roughened preparatory to the electrolytic deposit of metal forming the background for said letters. Due to the method of making sign plates according to the above-identified Spencer patent, the residual surfaces of the plate glass are closely bordered by an irregular line of metal which materially reduces the light-transmitting capacity of the letter-forming areas of the plate glass and thus reduces its visibility to the eye of a distant observer. For the purpose of overcoming these drawbacks while at the same time providing enhanced ornamental effects in devices of this character, our present invention contemplates a primary excavation of the lighttransmitting slab to produce the desired design in relief and to provide translucent side walls to the relief characters; the temporary placement of layers of resist on the translucent side walls for preserving their form and light properties during subsequent operations on the slab; the trimming of said resist layers to establish a definite border line at the base of the bevelled side walls; a secondary excavation of the slab around the trimmed edges of the resist layers on the bevelled side walls of the letters to form a barrier at the common base of the relief characters; and preventing the electrolytic deposit of metal on the bevelled side walls of the characters in relief. It will be understood that while a sandblast has been referred to as the agent employed for the primary and secondary excavating operations, other suitable agents may be employed for this purpose.
Our invention has been illustrated in the drawing in an adaptation to the construction of a plate glass sign provided with letters which stand out in bold relief from an electroplated roughened background, said letters being provided with roughened bevelled sides and with polished top surfaces formed by residual portions of the original surface of a color-flashed slab of plate glass.
In the drawing Figure l is a fragmentary section of a plate glass slab with a flashed layer of colored glass at the top and with a resist sheet applied to the top surface thereof.
Figure 2 is a fragmentary section of the plate glass slab at the conclusion of the primary sand blast excavation around portions of the slab which are to form a design in relief.
Figure 3 is a fragmentary section similar to Figure 2 after the bevelled side walls of the relief design have been covered by a special resist composition for protecting the bevelled side walls of the relief design from injury during the secondary sand-blast excavation as well as for excluding the conductive coating from said bevelled side walls while preparing the depressed background area for the electrolytic deposit of metal.
Figure 4 is a fragmentary section similar to Figure 3, showing the plate glass slab after the secondary sand-blast operation has been completed and the conductive coating applied to the roughened surface left by the secondary sandblast operation.
Figure 5 is a fragmentary section on the line 5-5 of Figure 6.
Figure 6 is a face view of one end of the completed ornamental panel in the form of a plate 5 glass sign.
According to Figure 1 of the drawing, a slab I of plate glass has been covered by a sheet 241 of resist which is to be cut away around and exterior to portions of the plate glass surface which are to form the top smooth surfaces of the letters shown in Figure 6. Said portions having been cut away, the uncovered surface of the plate glass is exposed to a primary sand-blast or other excavating agency until the roughened areas 2 surrounding the residual lens-like portions 3 have been depressed to the desired extent. At the conclusion (exhibited in Figure 2) of this primary excavating treatment, the lens-like portions 3 are left with concavely bevelled side wall surfaces 4 which merge outwardly into the roughened areas 2 and eventually constitute the translucent side walls of the finished letters. For the purpose of protecting the bevelled side walls 4 of the letters during the secondary excavating treatment, said walls are covered by a suitable protective covering 5 which is sufficiently resistant to the sand blast to protect the bevelled walls and to maintain a sharply defined border line outside of which the secondary excavating treatment is to be performed; which preferably adheres with sulficient closeness to the bevelled walls to prevent access thereto of the subsequently applied conductive coating; and
. which also can be removed readily either before or after the electroplating or other suitable treatment for forming an opaque covering to the depressed roughened background. After the layers 5 have been applied to the bevelled walls as shown in Figure 3, the outer edges of said layers are trimmed to sharply define the borders of the outwardly bevelled walls of the letters from the surrounding areas which are to be treated by a secondary excavating treatment to provide a depressed roughened background. The secondary sand blast is then applied around the outer borders of the resist layers 5 to form a depressed roughened background area 6, Figure 3, within which the lens-like bodies of the letters are sharply defined by abrupt shoulders 1, resulting from the trimming of the lower edges of the resist on sharply defined lines free from the contour irregularities of the depressed roughened background areas. The background areas 6 are next to be covered with an opaque layer of material which is preferably done by an electroplating operation. For this purpose, a conductive layer 3, Figure 4, is applied to the roughened background areas after which the prepared panel is placed in an electroplating bath for depositing the metal plate background 9, Figure 5.
