MODEL FOURTEEN SINGLE KEYBOARD
On the new model 14, known as model 14 single keyboard, there are 34 channels and short keyrods on the auxiliary instead of 28. These keyrods are operated from the regular keyboard. There is a lug pressed in the back of the keyrods. These lugs are staggered on the various keyrods and come in contact with a series of pivoted levers in a box containing 34 of these levers, fastened at the back of the keyrods of the main part of the machine.
The main keyrods, from the figure 1 up to and including the caps (34 in all), have a lug pressed into the back side of them. These lugs are also staggered on the keyrods so they can be brought into contact with the fulcrumed levers in the box. This box is known as a bail box.
The upper keyrod guide slots are made longer for these keyrods to slide back or forth, actuated by a hand lever that is placed below the assembler entrance and resting on the delivery slideway. The auxiliary is brought into operation by shoving back on this lever, which brings the keyrods and lugs in contact with the bail box levers, and they in turn operate the keyrods of the auxiliary whenever a key is touched.
