Abstract
Abstract An electromechanical indicating device for selectively displaying a plurality of symbols having a permanent magnet rotor, to which a symbol carrying cover is coupled, which is selectively deflectable to a plurality of discrete angularly spaced positions by selective energization of the excitation coils or windings placed on the pole pieces of the stator which is formed from a single piece of magnetizable material. The axes of the pole pieces of the stator and windings thereon are parallel to the vertical of rotation of the rotor. The symbols are on the vertical outer surface of the cover which has a height substantially greater than the outer periphery thereof divided by the number of symbols thereon. Deflection of the rotor is preferably brought about by selective energization of two or three adjacent windings.

Claim 1
Independent Claim
221 words
In an electromechanical rotary indicating device for selectively displaying a pluralitY of symbols in response to electrical energization, said indicating device being of the type including a stator having a plurality of magnetizable pole pieces and a magnetizable yoke portion connecting the pole pieces together at one end thereof, a separate excitation coils axially mounted on each of said pole pieces, a permanent magnet rotor rotatably mounted between said pole pieces for rotation about an axis transverse to the direction of magnetization of said rotor, circuit means for selectively energizing said coils to position said rotor to a selected one of a plurality of discrete angularly spaced positions, and a cylindrical cover having the symbols to be indicated thereon and coupled to said rotor for rotation therewith, the improvement wherein; said stator pole pieces are disposed with their axes parallel to the axis of rotation of said rotor; said stator is formed from a single piece of magnetizable material with said pole pieces being substantially perpendicular to said yoke portion; the axis of rotation of said rotor is in a vertical plane; and said cover substantially surrounds said pole pieces and has said symbols on the vertical outer surface thereof, said cover having a height which is substantially greater than the outer periphery thereof divided by the number of symbols thereon.

In an electromechanical rotary indicating device for selectively displaying a pluralitY of symbols in response to electrical energization, said indicating device being of the type including a stator having a plurality of magnetizable pole pieces and a magnetizable yoke portion connecting the pole pieces together at one end thereof, a separate excitation coils axially mounted on each of said pole pieces, a permanent magnet rotor rotatably mounted between said pole pieces for rotation about an axis transverse to the direction of magnetization of said rotor, circuit means for selectively energizing said coils to position said rotor to a selected one of a plurality of discrete angularly spaced positions, and a cylindrical cover having the symbols to be indicated thereon and coupled to said rotor for rotation therewith, the improvement wherein; said stator pole pieces are disposed with their axes parallel to the axis of rotation of said rotor; said stator is formed from a single piece of magnetizable material with said pole pieces being substantially perpendicular to said yoke portion; the axis of rotation of said rotor is in a vertical plane; and said cover substantially surrounds said pole pieces and has said symbols on the vertical outer surface thereof, said cover having a height which is substantially greater than the outer periphery thereof divided by the number of symbols thereon.
Claim 3
Dependent Claim
43 words
The electromechanical indicating device defined in claim 1 wherein said stator comprises a single piece of flat magnetizable material which has been cut to the desired shape, and said pole pieces being bent so that they are substantially perpendicular to said yoke portion.
Claim 4
Dependent Claim
16 words
The electromechanical indicating device of claim 1 wherein said rotor is a two pole tube-shaped rotor.
Claim 5
Dependent Claim
28 words
The electromechanical indicating device defined in claim 1 wherein the number of said pole pieces is equal to one half of the number of symbols to be indicated.
Claim 6
Dependent Claim
47 words
The indicating device defined in claim 4 wherein said rotor is cylindrical and has a plurality of equally spaced grooves formed in the periphery thereof, whereby said rotor is divided into a number of pole-type protrusions which is a multiple of the number of said pole pieces.
Claim 7
Dependent Claim
55 words
The indicating device defined in claim 4 wherein said circuit means simultaneously energizes either two or three adjacent excitation coils depending on the particular symbol desired to be indicated to thereby respectively position said rotor either between the corresponding two adjacent pole pieces or opposite the center one of the corresponding three adjacent pole pieces.
