System uses a method of securing a cam to a rotatable shaft in a discrete angular position with respect to the shaft. The device uses leaf springs along the inside diameter of the cam to lock individual sets of cam teeth to the shaft splines. Circumferential placement of the cam teeth sets of the cam permit no more than one set of cam teeth to be fully engaged with a shaft at any one time. This provides smaller and more numerous possible incremental angular positions of the cam with respect to the shaft while the remaining partially engaged sets of cam teeth provide a locking normal force to secure the cam and the fully engaged cam teeth set onto the shaft.

Cam system capable of small discrete angular cam positions relative to a rotatable shaft

A valve position transmitter which is comprised of an indicator assembly having a base with an aperture located thereon, an adjusting ring placed on the base about the aperture, an indicator member capable of identifying the operational position of a remote valve said indicator member being positioned on the adjusting ring, and a transparent cover placed about said indicator and secured to the base of the indicator assembly. Said valve position transmitter also comprising a shaft assembly extending from the point where it may be coupled to a valve through the aperture in the base of the indicator assembly to a point where it engages with the indicator member such that any rotation of the shaft assembly is sensed by said indicator member and some display with respect to such rotation is made. The valve position transmitter may also be comprised of a switch box assembly comprising a housing wherein are located switches for detecting rotation in the shaft member, said switches being electrically connected to a terminal strip and in turn said terminal strip being connected to remote peripheral devices. Said valve position transmitter may also be comprised of a split shaft assembly wherein upper and lower shaft members are provided for such that a peripheral device may be permanently coupled to said upper shaft member and it may be removed along with the upper shaft member to allow for easy field servicing of the remainder of the device.

Valve position transmitter

There is disclosed a novel indicator assembly comprised of a housing member mounted to a fluid handling apparatus and an indicator member mounted for rotation within the housing member operationally associated to a moving member of the fluid handling apparatus wherein the housing member is provided with transparent sectors permitting visual observation of the indicator member and wherein the indicator member is provided with colored sectors to visually cooperate with the transparent sectors of the housing member to indicate operational modes of the fluid handling apparatus.
