Fiber type light transferring devices and method of making the same

Claim 1

A FACE PLATE OF THE DESCRIBED COMPRISING A FIRST MEMBER FORMED OF A PLURALITY OF GLASS OPTICAL FIBERS SECURED TOGETHER IN HERMETICALLY SEALED FUSED SIDE-BY-SIDE RELATION SO THAT CORRESPONDING OPPOSITE ENDS OF SAID FIBERS COOPERATE TO DEFINE RESPECTIVE LIGHT-RECEIVING AND LIGHTEMITTING OPPOSITE FACES, THE EDGE OF SAID FIRST MEMBER BEING TAPERED CONVERGENTLY TOWARD ONE OF SAID FACES AND HAVING A CONTINUOUS SUBSTANTIALLY EVEN SURFACE, A SECOND GLASS MEMBER OF RIM-LIKE CONFIGURATION HAVING A CONTINUOUS SUBSTANTIALLY EVEN SURFACES INNER TAPERED EDGE OF APPROXIMATELY THE SAME PERIMETRIC CONTOUR SHAPE AND DEGREE OF TAPER AS SAID EDGE OF SID FIRST MEMBER, SAID FIRST AND SECOND MEMBERS BEING MATED WITH RESPECTIVE TAPERED EDGES THEREOF IN SIDE-BY-SIDE RELATION AND INTERJOINED BY A FUSED HERMETICALLY SEALED CONNECTION.

Claim 3

THE METHOD OF MAKING A DEVICE OF THE CHARACTER DESCRIBED COMPRISING PROVIDING A PLATE-LIKE GLASS FIBER PART OF PRESELECTED THICKNESS CONTOUR SIZE AND SHAPE EMBODYING A PLURALITY OF GLASS FIBERS IN FUSED HERMETICALLY SEALED SIDE-BY-SIDE CONNECTED RELATION WITH EACH OTHER, ABRADING THE PERIPHERAL EDGE PORTION OF SAID FIBER PART TO PRODUCE A TAPER THEREON AND SIMULTANEOUSLY FORMING SAID FIBER PART TO A DESIRED FINISHED CONTOUR SIZE AND SHAPE BY SAID ABRASION, SELECTING A GLASS RIM PART OF A DESIRED CONTOUR SIZE AND SHAPE GREATER THAN THAT OF SAID FIBER PART, ABRADING THE INNER EDGE PORTION OF SAID RIM PART TO A PERIPHERALLY TAPERED CONTOUR SIZE AND SHAPE SUBSTANTIALLY MATCING THAT OF THE ABRADED EDGE PORTION OF SAID FIBER PART, ASSEMBLING SAID PARTS WITH THE RESPECTIVE ABRADED EDGE PORTIONS THEREOF IN INTERFITTING RELATION WITH EACH OTHER AND HEATING SAID ASSEMBLED PARTS TO A TEMPERATURE SUFFICIENT TO PRODUCE A FUSED HERMETICALLY SEALTED CONNECTION THEREBETWEEN.

Claim 4

THE METHOD OF MAKING A DEVICE OF THE CHARACTER DESCRIBED COMPRISING PROVIDING A PLATE-LIKE GLASS FIBER PART OF PRESELECTED THICKNESS CONTOUR SIZE AND SHAPE EMBODYING A PLURALITY OF GLASS FIBERS IN FUSED HERMETICALLY SEALED SIDE-BY-SIDE CONNECTED RELATION WITH EACH OTHER, ABRADING THE PERIPHERAL EDGE PORTION OF SAID FIBER PART TO PRODUCE A TAPER THEREON AND SIMULTANEOUSLY FORMING SAID FIBER PART TO A DESIRED FINISHED CONTOUR SIZE AND SHAPE BY SAID ABRASION, SELECTING A GLASS RIM PART OF A DESIRED CONTOUR SIZE AND SHAPE GREATER THAN THAT OF SAID FIBER PART, ABRADING THE INNER EDGE PORTION OF SAID RIM PART TO A PERIPHERALLY TAPERED CONTOUR SIZE AND SHAPE SUBSTANTIALLY MATCING THAT OF THE ABRADED EDGE PORTION OF SAID FIBER PART, ASSEMBLING SAID PARTS WITH THE RESPECTIVE ABRADED EDGE PORTIONS THEREOF IN INTERFITTING RELATION WITH EACH OTHER AND HEATING SAID ASSEMBLED PARTS TO A TEMPERATURE SUFFICIENT TO PRODUCE A FUSED HERMETICALLY SEALTED CONNECTION THEREBETWEEN.
