A loader and unloader mechanism is attached to a standard photoplotter equipment. The mechanism performs a sequence of operations for loading and unloading sheets of film onto and from respectively such equipment completely automatically.

Film loader and unloader mechanism

A tool facilitates the hand insertion of wire wrap square sectioned pins from a fanning metal strip into plated through holes of a wire-wrap printed circuit board. The tool includes a solid cylindrical tip which is mounted within a handle member which includes an automatic anvil. An end portion of the tip has a portion with stepped profile which contains a round hole. The hole is slightly larger than the square section of the pin and has a predetermined depth for positioning the pin in a vertical direction during an insertion operation. The sizes of the individual steps are selected to enable the pins to be ejected completely from the band portions of the strip into the holes of the board at a predetermined depth without damaging the strip or the areas surrounding the holes.

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.
