Abstract:
A SLIDE IS DISPOSED IN A LONGITUDINAL SLOT IN ONE WALL OF A CASE, IN WHICH THERE ARE PARALLEL RESISTANCE AND COLLECTOR ELEMENTS. THE SLIDE CARRIES A BRIDGING CONTACT ENGAGING BOTH ELEMENTS, AND IS PROVIDED WITH A PASSAGE EXTENDING INWARDLY AT LEAST AS FOR AS THE SLOT. ROTATABLY MOUNTED IN THIS PASSAGE IS A SHAFT, THE INNER END OF WHICH IS PRESSED AGAINST THE CASE AT ONLY ONE SIDE OF THE SLOT. A KNOB ON
THE OUTER END OF THE SHAFT TURNS IT SO THAT THE FRICTION OF THE SHAFT AGAINST THE CASE WILL CAUSE THE SLIDE TO MOVE ALONG THE SLOT.
