ABSTRACT:
A universal adaptor for easily and efficiently mounting a signal device and/or directional indicator on the shafts of most manually actuated quarterturn valves and a method of securing a variety of signal devices and/or directional indicators to a variety of manually actuated quarterturn valves. The universal adaptor includes a cylinder mounted in a hollow adaptor housing. The cylinder is rotatable in the housing by operating a handle connected to the cylinder and extending outwardly through a radial slot in the adaptor housing. An interchangeable insert is positionable in a bottom opening in the cylinder. The insert has a bore which can be selected to engage a desired valve shaft. The universal adaptor is mounted to a valve by inserting an appropriate insert into the cylinder and then securing the adaptor housing to the valve shaft housing. The invented adaptor also includes a top mounting plate that enables the invented adaptor to couple a variety of signal devices and/or directional indicators to the valve shaft. A signal device and/or directional indicator is mounted on the universal adaptor by securing the signal device and/or directional indicator to an appropriate top mounting plate and then securing the top mounting plate to the adaptor housing. A second interchangeable insert may be used to adapt the top mounting plate to the cylinder. The invented universal adaptor allows "off the shelf" mounting of a signal device and/or directional indicator to a manually actuated quarterturn valve.
