Ribbon resistor with supporting means

Claim 2

A support means for a continuous ribbon-type resistor fanfolded into a plurality of equally spaced parallel uniform linear lengths connected by U-shape folds, comprising a frame having portions at opposite ends of said resistor opposite said linear lengths, supports connected between said frame portions, one support extending crosswise of said fanfolds on each side of said resistor, there being an opening through said ribbon resistor at the apex of each U-shape fold, projections carried by said supports, one projection opposite each of said openings, each of said projections being loosely received in its associated opening, means electrically insulating said resistor from said supports and from said frame, and terminals attached to said resistor.

Claim 3

A support means as defined in claim 1, including two of said openings being provided at the apex of each U-shape fold, two of aid projections, one entering each of said openings, and said openings and said projections lying on a line parallel to said linear lengths and extending axially of each U-shape fold at its apex.

Claim 4

A support means as defined in claim 2, including insulator blocks firmly mounted on said supports, and said projections being mounted in said blocks.

Claim 5

A support means as defined in claim 3, wherein said frame comprises uninterrupted end plates at each end of said resistor at right angles to said insulator blocks and extending to predetermined levels above and below the ribbon of said resistor, said insulator blocks extending from end plate to end plate to provide substantially uninterrupted walls on side adjacent and just outside said U-shape folds, and said blocks terminating at said predetermined levels, whereby a plurality of said support means may be stacked vertically with said blocks and end plates in registration whereby to provide an open vertical tunnel for forced ventilation.

Claim 6

A support means as defined in claim 2, wherein plates are firmly mounted on said supports, and projections are rigid with said plates.

Claim 7

A support means as defined in claim 2, wherein plates are firmly mounted on said supports, and projecTions are integral with said plates.

Claim 8

A support means as defined in claim 1, including two of said openings being provided at the apex of each U-shape fold, two of said projections, one entering each of said openings, and said openings and said projections lying on a line parallel to said linear lengths and extending axially of each U-shape fold at its apex, each of said supports comprising a bolt running the full length of said resistor and beyond said frame end portions, said insulating means including insulator blocks positioned end to end along said bolts, there being suitable openings through said blocks to receive said bolts, interengaging means on the engaging ends of adjacent blocks holding said blocks in registration, interengaging means between the end block on each bolt and the adjacent frame end portion to provide rigidity, said projections mounted in said blocks, and nuts threaded on the ends of said bolts and pulled up tight against the outer surfaces of said frame end portions and holding said blocks and said frame end portions assembled with said resistor held on said projections, there being insulating means between said nuts and said end portions.

Claim 9

A support means as defined in claim 1, including two of said openings being provided at the apex of each U-shape fold, two of said projections, one entering each of said openings, and said openings and said projections lying on a line parallel to said linear lengths and extending axially of each U-shape fold at its apex, a vertically extending plate opposite each of said U-shape folds, each pair of said projections being vertically spaced on one of said plates, there being two of said supports on each side of said resistor, each of said supports comprising a bolt running the full length of said resistor and beyond said frame end portions, there being two openings through each of said plates through which the associated bolts pass, an electrically insulating tube surrounding each of said bolts between said frame end portions, said tubes extending through said openings in said plates, hollow spacers surrounding said tubes between said plates and between the last plate on each bolt and the adjacent frame end portion, electrically insulating means between spacers and said plates and between said spacers and said frame end portions, and nuts threaded on the ends of said bolts and pulled up tight against the outer surfaces of said frame end portions and holding said plates and said spacers and said frame end portions assembled with said resistor held on said projections, there being insulating means between said nuts and said end portions.
