Abstract: A clock construction, a Geneva clutch therefor and methods of making the same are provided, the clock construction comprising a frame, a drive unit carried by the frame, a time indicating unit carried by the frame, and a Geneva clutch carried by the frame and operatively interconnecting the drive unit to the time indicating unit so that the drive unit can drive the time indicating unit in a timed sequence thereof, the clutch comprising a shaft rotatably carried by the frame, a pair of leaf springs each having opposed ends with a longitudinal axis therebetween, one of the opposed of each leaf spring being fixed to the shaft so that the leaf springs rotate in unison therewith, and a Geneva pinion rotatably disposed on the shaft and having a multi-sided section engaged by the leaf springs to tend to cause the shaft to rotate in unison with the pinion about an axis of rotation as the pinion is being rotated by the drive unit, the leaf springs each having the longitudinal axis thereof disposed substantially transv

Abstract: A control device having a housing provided with a main lever pivotally mounted thereto by a pivot structure and being operatively associated with a flapper to move the same relative to a leakport in relation to pivotal movement of the main lever. The device has a feedback diaphragm operatively associated with a feedback lever that is pivotally mounted to the housing and is operatively associated with the main lever to cause pivoting thereof upon pivoting movement of the feedback lever by the feedback diaphragm. The device has means for selectively changing the device to be either direct acting or reverse acting by changing the position of the feedback lever and the flapper and without changing the position of the feedback diaphragm and the leakport.

Abstract: A gage construction having a casing body provided with a generally circular front face interconnected to a rear mounting flange by an annular side wall disposed therebetween and which generally increases radially outwardly from the front wall to the rear mounting flange, the side wall having a generally polygonal exterior surface portion adjacent the rear mounting flange and a generally frusto-conical exterior surface portion adjacent the front face. The surface portions blend together between the front face and the rear mounting flange.

Abstract: An instrument casing having an opening therein exposing a pointer and a dial therefor. A flexible sealing member is carried by the casing adjacent the opening thereof. A lens is disposed in the opening and is provided with an outer periphery that is disposed against the sealing member. A lens ring is disposed against the other side of the outer periphery of the lens to hold the lens in the casing opening. The lens ring has an interlocking part thereof disposed against the outer peripheral edge of the lens between the sides thereof to lock the lens ring to the casing and, thus, the lens in the casing opening. A separate annular spacing member is disposed in the casing opening against the end wall thereof to hold the sealing member in spaced relation from the dial plate.
