Cathode ray tube mounting means including lighting means and camera-connecting means
First Claim
1. A cathode ray tube mounting means for mounting a cathode ray tube having projection means thereon in position in an electronic cabinet, comprising:
- a front casting having an opening therethrough and through which the cathode ray tube is moved;
guide means provided by said front casting adjacent said opening;
movable means movably disposed in said guide means for matable engagement with the projection means when the cathode ray tube is moved through said opening;
bezel means having implosion shield means therein securable onto said front casting; and
means provided by said movable means and engageable through said bezel means to move said movable means along said guide means thereby moving a faceplate of the cathode ray tube against said implosion shield means.

Abstract
A cathode ray tube mounting means includes a front panel member having an opening through which a cathode ray tube is passed, and it has projections on its funnel section that mate with wedging members movably mounted in the panel member. A bezel having an implosion shield means therein is secured onto the front panel member and the wedging members are secured into position thereby moving the faceplate of the cathode ray tube into tight engagement with the implosion shield means. Lighting means is disposed between the front panel member and the bezel adjacent the faceplate to effectively light the graticule scale of the cathode ray tube screen and to permit easy replacement of light bulbs. A connecting means is also provided for electrically connecting a camera to the circuitry within the electronic instrument containing the cathode ray tube.

5. Lighting means for illuminating internal graticule lines on a surface of a cathode ray tube faceplate comprising:
-
front casting means including mounting means for removably mounting a cathode ray tube thereon; bezel means surrounding the cathode ray tube faceplate and being mounted on said front casting means; light guide means extending along an edge of the faceplate and having spaced openings therein; means securing said light guide means onto said bezel means and including holes therethrough and through said bezel means in alignment with said spaced openings respectively; light bulb means disposed in said holes and spaced openings; conductive means provided on said securing means electrically engaging respective terminals of said light bulb means; and means connected to said conductive means for providing electrical potential thereto to energize said light bulb means. - View Dependent Claims (6, 7, 8)
