v. The brackets 11,
means of screws passing through the block i is provided Jfor the transmitter box in and rigidly secured in the transmitter casing. The ends of these screws, which are preferably platinum pointed, extend through bearing holes'in the brackets 11, 11 and engage contact points on the springs `13, 13'. 11 are secured in place by 15 and since this block is of insulating material, the brackets are insulated from each other and can therefore be used as terminal connections for the electrodes of the variable resistance element which are electrically connected to the contact screws 12, 12. mounting vand a counterweight 14; is provided so that irrespective of the position of the transmitter box, the transmitter itself will be in such 'a position that satisfactory transmission will result. Since the efficiency of the transmitter is only aHected by movement in plane perpendicular to the diaphragm, vit, is necessary to provide for automatic adjustment in that lplane only. Located at the bottom of the outside of the transmitter box is a or similar material jacks 7, 7 A four-conductor plug 16 adapted to engage the jack'?, 7 is connected to a exiblecord 17 by means of which the-necessary/circuit connections are made to the other station or to intermediate apparatus.
