Definitions

  • This invention relates to a resistor, and more particularly, to a variable resistor.
  • My invention comprises a variable resistor comprising a piece of resistance material having various shapes and numbers of isolated resistance material portions therein, said portions being an integral part of said piece.
  • My invention further comprises a variable or adjustable non-linear resistor comprising a piece of non-linear resistance material having various shapes and numbers of isolated non-linear resistance material portions therein, said portions being an integral part of said piece.
  • Fig. 1 is a perspective view of one form of my invention.
  • Fig. 2 is a sectional side View of the variable resistor shown in Fig. 1, the section being taken along the line 22 of Fig. 1.
  • Fig. 3 is a top view of another form of my invention.
  • Fig. 4 is a top view of still another form of my invention.
  • Like reference numerals in the various figures refer to identical parts.
  • a non-linear resistance material mean a material which will present a low resistance when subjected to a high voltage and which will present a high resistance when subjected to a comparatively low voltage.
  • a resistance material is well known in the prior art and one form thereof and method of making same is shown and described in Patent 1,822,742, issued September 8, 1931, to K. B. McEachron and assigned to the same assignee as the instant application.
  • my invention is also applicable to a linear resistor wherein piece or disk 10 would be constructed out of a linear resistance material.
  • isolated nonlinear resistance material portions are formed within the piece 10.
  • Said isolated portions are an integral part of piece 10, and can be formed by various methods.
  • a well known process that can be employed is the Schoop process.
  • conducting coatings 11, 12 are applied to predetermined areas of the upper surface of piece 10.
  • a conducting coating 13 is applied to the opposite side or bottom surface of the piece or disk 10.
  • Bolt or pin 14 is insulated from the non-linear resistance material piece or disk 10 by an insulating material gasket or bushing 16.
  • a spring element or washer 17 Surrounding pin 14 and disposed between the head of pin 14 and contact plate 15 is a spring element or washer 17 whereby when a nut is turned down on the threaded end of pin 14 the contact plate 15 will be urged against the coatings 11 and 12 for intimate broad surface contact therewith. Electrical leads 18 and 19 can be connected to contact means 15 and coating 13 respectively by soldering or the like whereby the piece 10 can be placed in an electrical circuit.
  • the resistance of the non-linear resistor 10 can be varied. That is to say, different combinations of schooped portions 11 and 12 can be electrically connected in parallel whereby the effective resistance of piece 10 can be varied.
  • FIG. 1 upon a 90 degree clockwise rotation of contact means 15 it will be seen that only the schooped portion 12 will be placed in the electrical circuit. If the contact means 15 is rotated 90 degrees counterclockwise then all the schooped areas 11 are placed in the electrical circuit. Also, by partial rotation of the contact means 15 the schooped area 11 and one or more of the schooped areas 11 can be placed electrically in parallel.
  • the adjustable non-linear resistor comprises a flat circular disk 20 of non-linear resistance material.
  • Formed on the disk 20 are a plurality of isolated concentric arc-like schooped portions 21, 22, 23, and 24.
  • the contact means comprises a fiat elongated arm 25. By rotating arm clockwise one or more of the isolated concentric arc-like schooped portions 21, 22,
  • the adjustable non-linear resistor comprises aflat circular disk 3015f non-linear resistance material having aflat elongated contact arm 31 movable over the upper surface of said disk '30.
  • Within disk 30 are formed isolated concentric arc-like sc'hooped areas 32, 33, 34 and 35 which have adifierent configuration and arrangement from the isolated schooped areas shown in Fig. 3 whereby it will be obvious that the resistance of the non-linear resistance material disk 30 can be adjusted at different increments depending upon theconfigurations and number of the isolated schooped areas.
  • a variable non-linear resistor comprising a fiat 'disk of non-linear resistance material, a plurality of isolated predetermined areas of the upper surface of said disk having a conducting coating applied thereto, the bottom surface of said disk having a conducting coating applied thereto, and rotatable contact means cumulatively engageable with said plurality of coatings on said upper surface.
