Abstract
Electromechanical pulse counter with a housing, wherein a current carrying spool and coil means is secured, whereby the spool and coil means surround an iron core, an air gap defined between the iron core and an armature anchor, preferably in the form of a plate-like armature anchor, responsive to the magnetic field of the spool and coil means. The armature anchor is movably mounted in the housing, and actuates an escapement anchor, having a control fork which, stepwise, by the intervention of a gear drive, rotates at least one indicator wheel having indicator numbers on its circumference. The iron core is positively held at the housing part which comprises a support for the armature anchor, and the iron core is journalled so as to be movable with respect to the spool and coil means.
Claims18
An electromechanical pulse counter, comprising, in combination:
- a walled counter housing;
- an iron core having first and second arms, said first arm being positively securable in a pertaining wall of said housing;
- spool and coil means operatively secured in said housing for the provision of a magnetic field, said spool and coil means surrounding said second arm of said iron core;
- whereby said second arm is movably disposed within said spool and coil means;
- an armature mounted near said pertaining wall holding said first arm, said armature being responsive to a magnetic field provided by said spool and coil means;
- said armature and said core being spaced from one another so as to form an air gap;
- an escapement anchor mounted in said housing actuable in response to movement of said armature, said escapement anchor including at least a fork member;
- at least one rotatable indicator wheel mounted in said housing, said indicator wheel having circumferentially disposed count indicative insignia and being stepwise rotatable in response to actuation of said escapement anchor;
- gear drive means operatively connectible between said fork member and said at least one indicator wheel for rotation of a pertaining indicator wheel, said gear drive means including at least one gear actuable by said fork member of said escapement anchor,
- said armature including a plate-like armature anchor,
- said housing including an opening in the pertaining wall and wherein said iron core includes a projection securably mountable in said opening.
An electromechanically operable pulse counter, comprising, in combination:
- a walled counter housing;
- an iron core having first and second arms, said first arm being positively securable in a pertaining wall of said housing;
- spool and coil means operatively secured in said housing for the provision of a magnetic field, said spool and coil means surrounding said second arm of said iron core;
- whereby said second arm is movably disposed within said spool and coil means;
- an armature mounted near said pertaining wall holding said first arm, said armature being responsive to a magnetic field provided by said spool and coil means;
- said armature and said core being spaced from one another so as to form an air gap;
- an escapement anchor mounted in said housing actuable in response to movement of said armature, said escapement anchor including at least a fork member;
- at least one rotatable indicator wheel mounted in said housing, said indicator wheel having circumferentially disposed count indicative insignia and being stepwise rotatable in response to actuation of said escapement anchor;
- and
- gear drive means operatively connectible between said fork member and said at least one indicator wheel for rotation of a pertaining indicator wheel, said gear drive means including at least one gear actuable by said fork member of said escapement anchor,
- at least two indicator wheels movably mountable in said housing;
- shaft means for mounting said at least two indicator wheels in said housing;
- a support frame system;
- shaft means for mounting pertaining gears of said gear drive means in said support frame system;
- a set part for resetting of said at least two indicator wheels to a commencement position in which a pertaining indicator wheel is disengaged from a pertaining gear;
- and
- guide means provided in said housing for movably guiding therein said support frame system, whereby said support frame system is directly frictionally connectible to said set part, and whereby said set part is disposed in said guide means and movable with respect to said support frame system on elimination of said frictional connection for resulting of said at least two indicator wheels to pertaining commencement positions.
