Abstract:
A hand held tool for installing compression rings includes a pair of relatively reciprocable coaxial cylindrical independently spring biased elements housed within a cylindrical handle which includes mode control means automatically preconditioned for enabling the tool to perform either an installation or ejection operation. The mode control means includes a cylindrical radial cavity containing plural spring biased spherical ball detents and extends into corresponding portion of the outer reciprocable element. The positioning of a tapered central section of the inner reciprocable element coincides with the cavity so that one of the spherical ball detents normally sits within a hollow defined by the taper. When one spherical ball detent, in response to the mode control means being preconditioned by depressing a front end or shaft portion of the inner element, is positioned to lock the outer member to the handle, this allows the ring to be installed onto the cam shaped front end of the outer element. In the absence of such preconditioning, one ball detent is positioned so that its outermost surface coincides with the outer surface of the outer element allowing the cam shaped front end to recede into the handle so that the installed ring can be ejected onto the device on which it is to be mounted.
