Description

CHRONOMETRIC SPEED REGULATOR WITH PULSE STABILIZATION

It was announced on June 18, 1951 for .4 447091/2675 to the Ministry of Mechanical Engineering and Instrument Engineering of the USSR

Published in the 1954 Bulletin of Inventions Xs 3

The proposed speed controller is a timed clock with pulse stabilization to a portable watch type.

The difference in the proposed speed regulator is that it is equipped with a lever under the action of a coil spring and carrying a gold spring that keeps the wheel from rotating and interacts with the trigger stone once for the complete balance fluctuation.

The attached drawing shows a speed regulator circuit.

Balance / with a large moment of inertia carries a pulsed stone 2 and a trigger stone 5 and receives one impulse for its full oscillation. The balance has the usual spiral spring (hair) 4.

The impulse lever 5, mounted freely on the axis between the stops, bears on itself a flat gold spring 6 and impulse stone 7. The impulse lever has a separate spiral (hair) 8 with adjustable tension.

An eight-tooth hook-and-wheel sprocket 9 is engaged with a gear 10 with a loose tube, on which a handwheel 11 is mounted, by means of a gear wheel 10.

In a balanced position, the trigger stone .3 bends the gold spring 6 and frees the cog wheel tooth 9. turning while under the action of the clockwork spring without moving back. The speed of rotation of the traveling wheel is slowed by the handwheel. Simultaneously, the pulse lever 5, freed from the action of the chassis tooth

the wheel 9 is rotated by the action of the spring 8 and imparts a pulse to the balance 1.

When the balance moves in the opposite direction, the pulse lever still does not complete its turn, due to the slowing action of the handwheel 11, and the trigger stone 3 of the balance passes freely, without hitting the golden spring ledge. Then, the tooth of the traveling wheel turns the impulse lever up to the stop and the traveling wheel stops, locked with a gold spring. After the trigger stone is pressed into the lip of the gold spring, it is lifted and the wheel is released, the cycle of operation of the speed regulator is repeated.

The speed regulator is actuated without balance buildup, as in the balanced position of the gold the spring sits between the trigger stone and the additional pin, and the traveling wheel turns the impulse lever, which immediately transmits the impulse to the balance.

Subject matter

A chronometer-type speed regulator with a pulse stabilization, characterized in that, in order to increase the accuracy of the clock, the controller is provided with a spiral pulse lever under the action of holding the spindle from holding the gold spring, which interacts with the trigger stone once for the full balance oscillation .
