Abstract
Abstract Multiposition bidirectional rotary means for a switch or the like includes a rotary ratchet operated by two actuating levers. Two advance levers slidably and pivotally mounted to engage this ratchet from opposite radial directions. Each advance lever has means for engaging the ratchet to rotate the ratchet one step to an adjacent position and means to engage the ratchet and releasably hold it in a position. One lever rotates it in one direction the other lever rotates it the opposite direction. Springs urge each advance lever toward the ratchet and tangentially thereof toward projected at rest positions. The push levers have projections to engage the advance levers for effecting lineal sliding movement and permitting pivoting of such advance levers relative to the ratchet and the push levers.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
114 words
A multiposition bidirectional rotary means for a switch or the like comprising: a rotatively mounted ratchet for rotating parts connected therewith, said ratchet having spaced teeth therearound; independently slidably and pivotally mounted advance levers positioned to engage said ratchet from radial directions and having means to engage said teeth and rotate said ratchet upon sliding movement of said levers; spring means for (a) urging said advance levers radially inward toward said ratchet and (b) sliding said advance levers tangentially of said ratchet; and slidably mounted actuating levers having means engaging an advance lever to permit relative pivoting therebetween, and to effect simultaneous lineal sliding motion of an advance lever and a respective actuating lever.
Claim 2
Dependent Claim
114 words
A multiposition bidirectional rotary means for a switch or the like comprising: a rotatively mounted ratchet for rotating parts connected therewith, said ratchet having spaced teeth therearound; independently slidably and pivotally mounted advance levers positioned to engage said ratchet from radial directions and having means to engage said teeth and rotate said ratchet upon sliding movement of said levers; spring means for (a) urging said advance levers radially inward toward said ratchet and (b) sliding said advance levers tangentially of said ratchet; and slidably mounted actuating levers having means engaging an advance lever to permit relative pivoting therebetween, and to effect simultaneous lineal sliding motion of an advance lever and a respective actuating lever.
Claim 3
Dependent Claim
55 words
A multiposition bidirectional rotary means as set forth in claim 1 in which: there is a mounting frame for said rotary means, said frame having bearing portions; said ratchet is a multiple tooth star wheel; and said advance levers have rounded bearing portions in sliding and rocking engagement with said bearing portions on said frame.
Claim 4
Dependent Claim
30 words
A multiposition bidirectional rotary means as set forth in claim 2 in which: said advance levers have ratchet hooks and blocking parts engageable with the teeth of said star wheel.
Claim 5
Dependent Claim
51 words
A multiposition bidirectional rotary means as set forth in claim 3 in which: said advance levers have notches; and said actuating levers have guide portions in sliding engagement with said bearing portions on said frame, and fingers cooperating with said notches to provide pivoting and sliding action for said advance levers.
Claim 6
Dependent Claim
31 words
A multiposition bidirectional rotary means as set forth in claim 1 in which: said advance levers and said actuating levers are formed of rigid materials and are constrained against resilient deflection.
