Abstract
Abstract A jig holds the electrodes of a miniature electrostatically deflected cathode ray tube in place while receiving molten glass rods to affix the electrodes in position. The jig holds the electrode parts with the tube axis horizontal in a series of slots and contoured receptacle chambers which are manually loaded and held in place by gravity until the jig is fully loaded. Separate pressure pad clamping arrangements are then positioned to bear both vertically and axially on the electrode parts to hold them precisely in position for receiving molten glass rods.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
169 words
An assembly jig for holding a plurality of diversely shaped electrodes of a cathode ray tube in exact spaced positions and orientated along a common axis with two opposed portions of the electrodes thereof extended with members for receiving thereon molten glass rods to permanently hold the electrodes in position, comprising in combination, a receptacle frame including a plurality of receptacles shaped for receiving said electrodes of different shape in said positions in axial alignment along said axis in a horizontally oriented array to receive the electrodes and hold them in initial position by force of gravity with said members extending in a substantially horizontal plane, a removable clamping frame having spring loaded pads for engaging each of the electrodes to press them into said shaped receptacles and hold them in said axial alignment and means affixing said clamping frame in place adjacent to said receptacle frame so that each of said pads engages an electrode when in place with a spring bias holding it in its corresponding receptacle.
Claim 2
Dependent Claim
169 words
An assembly jig for holding a plurality of diversely shaped electrodes of a cathode ray tube in exact spaced positions and orientated along a common axis with two opposed portions of the electrodes thereof extended with members for receiving thereon molten glass rods to permanently hold the electrodes in position, comprising in combination, a receptacle frame including a plurality of receptacles shaped for receiving said electrodes of different shape in said positions in axial alignment along said axis in a horizontally oriented array to receive the electrodes and hold them in initial position by force of gravity with said members extending in a substantially horizontal plane, a removable clamping frame having spring loaded pads for engaging each of the electrodes to press them into said shaped receptacles and hold them in said axial alignment and means affixing said clamping frame in place adjacent to said receptacle frame so that each of said pads engages an electrode when in place with a spring bias holding it in its corresponding receptacle.
Claim 3
Dependent Claim
25 words
An assembly jig as defined in claim 1 wherein the plurality of receptacles are individual modularized sections removably held in place in said receptacle frame.
Claim 4
Dependent Claim
31 words
An assembly jig as defined in claim 1 having a retractable end clamp assembly for holding at least one end electrode in axial position in a corresponding one of said receptacles.
Claim 5
Dependent Claim
53 words
An assembly jig as defined in claim 3 having an assembly for receiving two vertically spaced deflection electrodes at one end of the electrode assembly wherein said end clamp holds in position the lower deflection electrode in one of said receptacles and has thereon structure forming a receptacle for the upper deflection electrode.
Claim 6
Dependent Claim
34 words
An assembly as defined in claim 1 wherein at least a portion of the spring loaded pads comprise spring loaded pin extensions for engaging an electrode placed in a corresponding one of said receptacles.
Claim 7
Dependent Claim
19 words
An assembly as defined in claim 1 having a receptacle surface for cylindrical electrodes shaped with a V-shaped crotch.
Claim 8
Dependent Claim
52 words
An assembly as defined in claim 1 wherein the electrodes comprise at least one flat plate electrode including a receptacle for the plate electrode which comprises a plate having an indentation on one side and a spacer plate positioned adjacent the indentation to form a slot for receiving said flat plate electrode.
Claim 9
Dependent Claim
34 words
An assembly as defined in claim 7 wherein said flat plate electrode has two locating indents on one edge, and wherein said receptacle for the plate electrode includes locater pins registering with said indents.
