Abstract: 1,051,987. Sound producing instruments &c. F. CALDIRONI, A. OLIVIERI [trading as FRATELLI MEAZZI]. Feb. 19, 1964 [Feb. 21, 1963], No. 6809/64. Heading G5J. The tensions of the strings of a musical instrument can be altered to produce vibrato effects by anchoring them to the periphery of a cylinder 16 which can be rotated by a handle 22 against the resilience of a central torsion rod 10. The rod is fastened at one end to a mounting bracket 13 and at the other to one end of the cylinder. The other end of the cylinder rotates about the rod on ball-bearing 11. In order to assist the restoration of the strings to their original tensions when the handle is released, the bridge base-plate 26 is mounted on pins 32, 33 with rounded ends which rest in seatings so allowing the bridge to rock when the vibrato device is operated; no sliding movement between the strings and the bridge takes place. The bridge is also constructed in small sections 29 which are movable longitudinally for tuning the strings and are clamped by a through rod operated by lever 31. The bridge may be mounted separately from the vibrato device (Fig. 1. not shown).

A plurality of pressure rollers 1 are urged against driving rollers 28 and are supported on arms 13 so as to be simultaneously or individually pivoted clockwise away from the driving rollers. As shown, pressure roller 1 is normally urged against driving roller 28 by means of spring 27 acting via pivoted lever 23 pressing on the pin 9 carried by the pivoted roller supporting arm 3. The pressure roller 1 can be released from the driving roller in one of two ways. Firstly, the pressure roller 1 can be released by movement of shaft 18 to the left whereby a stop 21 abuts the roller supporting arm 3 and pivots it clockwise. (The spring 27 and lever 23 is simultaneously moved to the left). A plurality of pressure rollers 1 can thereby be simultaneously disengaged from their respective driving rollers. Secondly, the pressure roller can be disengaged from the driving roller 28 by pivoting lever 13 and pin 9 behind lever 23 (Fig. 2) and then pivoting the roller supporting arm 3 clockwise. A single pressure roller can thereby be disengaged from its associated driving roller without affecting other pressure rollers.

In the first phase switches 8 and 9 are closed and the output voltage from the transducer 1, and the output voltage from a second transducer 2 having the same supply but with its non-electric input held constant, are integrated in integrators 6, 12 and 7, 13 respectively. (Figs. 2a and 2c show the output voltage U from the transducer 1 and the output U, from integrator 6, 12). In the second phase switches 8 and 9 are opened, so that the outputs of the transducers remain steady, and the output U 2  from the second integrator 7, 13 is progressively attenuated by a potential divider 3 in which resistors 4 are sequentially switched into circuit under the control of a comparator 16, until the output U 3 , see also Fig. 2 (c), from the potential divider 3 balances the output U 1  from the first integrator 6, 12. The setting of switches 5 which control the potential divider is then indicative of the non-electric input to transducer 1.
