Abstract
A multirate dial register for meters having a rotatable measuring element includes plural sets of dial indicators having at least one set thereof selectively coupled by a clutch mechanism to the measuring element such that the ratio of measuring indications at the one set of dial indicators is controllable at the front of the register for converting between measurements of different parameters of a measured quantity by a solenoid actuated clutch wherein one solenoid plunger end controls the clutch and the opposite plunger end controls an on-off dial indicator.
Claims15
A convertible multirate dial register for meters having a rotatable measuring element responsive to the consumption of a quantity to be measured, said dial register comprising:
- a front plate having plural sets of clock dial indicia;
- a first set of dial indicators associated with a first set of dial indicia on said front plate;
- a first gear train continuously rotated in response to the rotation of said measuring element for driving said first set of dial indicators;
- a second set of dial indicators associated with a second set of said dial indicia wherein said second set of indicia are separately mountable to said front plate;
- a second gear train including a clutch mechanism operable between coupling and uncoupling states and having an input and an output with said clutch input being driven by said first gear train, and said second gear train further including shiftable gear means having first and second operating positions so as to be driven in response to said clutch output at either of first or second fixed rates of rotation when in said first or second operating positions, respectively, and said shiftable gear means further being in driving relationship with said second set of dial indicators so that said second set of dial indicators is rotatable at the same rate as said first set of dial indicators are rotated when said shiftable gear means is in said first operating position and at a different rate of rotation from said first set of dial indicators when said shiftable gear means is in said second operating position.
A convertible multirate dial register for meters having a rotatable measuring element responsive to the consumption of a quantity to be measured, said dial register comprising:
- plural sets of dials including a first set and a second set of dial indicators;
- first gear train means having an input for being continuously driven by said measuring element and an output driving said first set of dial indicators;
- second gear train means having an input being continuously driven by said first gear train means and an output selectively driving said second set of dial indicators, and
- gear shift means coupled between said input and said output of said second gear train means and having first and second axially shifted operating positions for effecting two predetermined fixed gear ratios between said input and said output of said second geaar train means such that one gear ratio produces the same predetermined rate of rotation at both the first and second dial indicators and such that the other gear ratio produces a different predetermined rate of rotation at said second set of dial indicators than at said first set of dial indicators when said second set of dial indicators is selectively driven.
A convertible multirate dial register for electric energy meters having a rotatable measuring element responsive to the consumption of a quantity to be measured, said dial register comprising:
- a front plate having plural sets of dial indicia;
- a first set of measuring dial indicators associated with a first set of dial indicia;
- a first dial gear train continuously rotated in response to the rotation of said measuring element for driving said first set of dial indicators;
- a second set of measuring dial indicators associated with a second set of said dial indicia;
- a second dial gear train including a first clutch mechanism operable between coupling and uncoupling states and having an input and an output, said input of said first clutch mechanism being driven by said first dial gear train, said second dial gear train further including gear shift means having first and second operating positions being driven in response to said output of said first clutch mechanism at first and second predetermined rates of rotation when in said first and second operating positions, respectively, and said gear shift means being in driving relationship with said second set of dial indicators when in either of said first and second operating positions so that said second set of dial indicator are rotatable at the same rate and at a different rate than are first set of dial indicators in response to said first and second operating positions, respectively, of said gear shift means when said first clutch mechanism is in said coupling state;
- a third set of measuring dial indicators associated with a third set of said dial indicia;
- a third dial gear train including a second clutch mechanism operable between coupling and uncoupling states and having an input and an output, said input of said second clutch mechanism being driven by said first dial gear train, said output of said second clutch mechanism being in driving relationship with said third set of dial indicators such that the first and third sets of dial indicators are driven at the same rate by said first gear train when said second clutch mechanism is in said coupling state.
