The device keyboard is as follows. A 2-chromatic keyboard, pins 3 and pins 4 and strings 5 strung on them are placed in the deck / keyboard.

In the housing of the bolster there is a drawer 7, inside of which is placed the whole mechanic of the instrument. Two brackets 8 are fastened to the back wall of the crate /. 8. In these brackets 8 an axis 9 is inserted, on which thirteen JO levers with dampers 7 / are fitted with three brushes on each arm. Each of the levers 70 is pressed from below by a spring 12 through dampers 7 / to the strings 5. There are thirteen such springs in terms of the number of levers. Each key of the keyboard 2 has a pin J3 and through it the key contacts the lever 70. Over all the levers 76 between the strings 5 there is a rod f4 connected through a system of levers 73, 76 and 77 with the pedal.
