Connecting device for radiation source column and film case carriage

The device consists of an articulated folding arm whose one part is pivoted on a plate attached to the radiation source column while the other is provided with springs and with a stirrup and a recess between the springs. The extended pin on the tomographic part is slidably fitted in the stirrup with recess. The pin is provided with an adjustable contact linked to the microswitch contact. In tomography, the operator mechanically connects the tomography bar fitted in a sleeve to the source, thus disconecting the articulated folding arm from the extended pin of the tomograph. The disconnected arm will then be folded in the vertical position by the action of gravity. At the same time, the microswitch contact displaying the arm position breaks. The double-sided stirrup design makes it possible to use the device in both right-hand and left-hand operation. (J.B.). 2 figs
