CLASS 83: Clocks.

Patented in the German Empire on August 8, 1889.

The novelty of the present invention consists in the fact that in pocket watches the well-known automatic vibrating winding mechanism (German patents No. 1903, No. 3939 and No. 14939) ^and the likewise known button winding mechanism are connected to one another in this way by adding an on and off switch of the button winding mechanism , that when the button winding (Remontoir) is switched off, the. automatic vibration winding (Perpetuale) is in action, while, if the clock is lying or hanging for a long time, resp. a shaking of the same or a movement with it does not take place at all or not to a sufficient extent that the spring can be drawn up by hand after switching on the button winding.

On the accompanying drawing, Fig. 1 shows the clockwork seen from behind with the vibrating mechanism. Fig. 2 shows the movement after removing the dial from the front with the new arrangement seen. The movement of the clock is arranged in a known manner and for clarity because of not shown.

As is known, in pocket watches with vibrating lifts, a lever b , held in equilibrium by a spring α, Fig. 1, moves with each movement of the wearer of the watch or by any other movement caused vibration of the watch and drives when it goes down through the locking cone c the gear wheel d a distance further. The drive e fixed to d is in engagement with the wheel f and the latter through its drive g with the wheel h , which through its drive i · moves the wheel / loosely rotating on the spring pin k , Fig. 1. On the wheel / two locking cones m are attached, which after each movement of the vibrating mechanism move the ratchet wheel η , which is firmly attached to the spring pin k , and thereby pull up the spring located in the spring house q.

An automatic switch-off of the vibrating mechanism, which also switches on again automatically prevents the spring from breaking by pulling it over too much if there is too much vibration.

In order to prevent the watch from coming to a standstill due to not winding the To avoid a clock spring, a button elevator is arranged on the vibrating elevator, which usually, Fig. 2, is off.

However, so that the vibrating mechanism can work unhindered when the clock is shaken sufficiently, the conical wheel ρ loosely seated on the winding shaft ο, which in the known button windings is always in engagement with the gear r firmly attached to the winding shaft ο , must be kept engaged. This half is ia of the circuit board of the two-armed lever rotatable by 5 'arranged tt, which, as Fig. 2 shows, with its ν by the spring upwardly depressed arm t the conical wheel ρ besides holding engagement with r. Only when the same through its second arm , which is on the outside. side of the watch case, except for the

When the pin w fixed in the plate is depressed, ρ engages r, and the watch can be wound by hand in a known manner by means of the button, as soon as this becomes necessary.

Claims (1)

Patent claim: In the case of a pocket watch, the connection of an automatic vibrating elevator with a button elevator whose winding wheel ρ (Fig. 2) is kept out of engagement with the wheel r by the lever tt ' and the spring ν , so that on the one hand the vibrating elevator work unimpeded and on the other hand, when it is too low Activity of the vibrating lift, the winding of the spring by hand after depressing the lever arm t ' can be effected by means of the button winding. For this purpose ι sheet of drawings.
