Abstract:
A Geneva Mechanism for intermittently driving a load, the mechanism comprising:a rotating driver having a drive pin;a star wheel operationally associated with a load which is to be intermittently driven, said star wheel comprising a plurality of radially extending slots, each of said radially extending slots being curved along a substantial portion of its length;said drive pin of said rotating driver being engageable with one of said radial extending slots to drive said star wheel in an incremental angular manner, such that a drive pin load on said drive pin and forces applied to the load operationally associated with said star wheel remain in control, and said star wheel reaches a peak acceleration and deceleration in a continuous and controlled manner;wherein each of said radially extending slots define a firstwall having a concave portion adjacent a mouth of said slot, a slightly convex portion along a middle portion of said slot, and a straight portion at an inner portion of said slot; anda second wall having a concave portion adjacent said mouth of said slot, a slightly convex portion along said middle portion of said slot, and a straight portion at said inner portion of said slot.
