Abstract

Abstract A mechanical governor and timer of the gear train type operative in combination with cyclically operating mechanisms, particularly game apparatus of the spinning reel type having a repetitious reversal pattern alternating in forward and reverse rotation phases in each duty cycle. Erratic timing and reel machine failure caused by localized gear and bearing wear produced in conventional timers due to the reversal pattern, is eliminated by a form of governor in which the input gear has as a part thereof an input spindle journalled in roller bearings operating in overriding clutch action in the gear hub and adapted for direct coupling with a countershaft component in the game apparatus to render the entire timing gear system unidirectional.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 207 words
In cyclically operable game apparatus of the type wherein a drive shaft is oscillated in each game cycle in a forward setting phase initially with reversal in a return stroke phase in which the speed thereof is regulated by governor means of the fan-loaded gear-train type, improvements in governor means characterized in that: the governor comprises a gear array including a large diameter input gear coupling with said drive shaft, and a small low-torque output gear driving a loading fan, together with a train of intermediate reduction gears drivingly interconnecting the input and output gears, said input gear being drivingly coupled with said drive shaft through a unidirectional clutch of the precision ball type operative to drive the input gear only in the direction of rotation of the drive shaft in the return phase thereof, such that the respective gears in the entire array are constrained always to turn in the same unidirectional progression through cumulatively complete revolutions, and no gear can be repetitiously oscillated in any game cycle operation of said drive shaft, whereby all of the teeth of all of the gears in the array will be exposed to wear stress notwithstanding repetitious oscillation of the drive shaft in repetitious cycling of said game apparatus.
Claim 2
Dependent Claim 207 words
In cyclically operable game apparatus of the type wherein a drive shaft is oscillated in each game cycle in a forward setting phase initially with reversal in a return stroke phase in which the speed thereof is regulated by governor means of the fan-loaded gear-train type, improvements in governor means characterized in that: the governor comprises a gear array including a large diameter input gear coupling with said drive shaft, and a small low-torque output gear driving a loading fan, together with a train of intermediate reduction gears drivingly interconnecting the input and output gears, said input gear being drivingly coupled with said drive shaft through a unidirectional clutch of the precision ball type operative to drive the input gear only in the direction of rotation of the drive shaft in the return phase thereof, such that the respective gears in the entire array are constrained always to turn in the same unidirectional progression through cumulatively complete revolutions, and no gear can be repetitiously oscillated in any game cycle operation of said drive shaft, whereby all of the teeth of all of the gears in the array will be exposed to wear stress notwithstanding repetitious oscillation of the drive shaft in repetitious cycling of said game apparatus.
Claim 3
Dependent Claim 82 words
Apparatus according to claim 1 further characterized in that said governor comprises a unitary assembly including a pair of parallel chassis plates between which the gears of said gear array are journalled, and said input gear includes an axially extending bore in which said clutch is set, said clutch including a coaxial bore in which is set an axially extending input stub-shaft having communication through at least one of said plates for joinder in driving engagement with the drive shaft as aforesaid.
