Abstract
Abstract A rotary programmer utilizing rotating cams actuating control members such as electric limit switches or valves, wherein the programmer is driven by a rotating shaft concentric with the shaft upon which the cams are mounted. A clutch mechanism externally located of the cam enclosing housing selectively clutches the driven shaft to the cam shaft to permit rotation of the cam shaft and cams relative to the driven shaft for adjustment purposes. The clutch mechanism is so constructed as to present no safety hazard as the same rotates, and an axial displacement of the clutch member produces clutching and declutching of the cam shaft to the driven shaft. A further feature of the invention utilizes exteriorly operated cam adjustment means permitting adjustment of the cams on the cam shaft by the use of the clutch mechanism without entering the cam housing.
