Description

^ * 'The innovation concerns a clock with a on the number j : ■ sheet of the clock readable temperature meter, the one through

besides the usual time mechanism for the purely optical time display, there are other additional mechanisms for various purposes

Enable time display ^ precisely delimited by seconds. to Mention should also be made of clocks with a mechanism that automatically switches to display the day and month.

; Clocks are also already known in different embodiments, which also have the temperature at the same time around the watch. This can be, as' " knows, so it happened that on the watch case or on the numeric

. * "Sheet or in the cover glass and the like a thermometer

is arranged in a visible and shockproof manner. This is with

Determination of the time and the ambient temperature can also be read off. In particular, it has already been proposed, as known, for this purpose to use either a more or less encapsulated thermometer in the form of a stick or a single piece filled with mercury, alcohol or the like. Same purpose is. also already one with a bimetal spring or the like | _r working dial thermometer known, which also

i: is already assigned to the dial or directly into the

|:% _; Dial of the clock is introduced. Each of such

I ' known design penetrates the pointer shaft of the bi

^: Dial fixedly arranged bearing piece is secured.

The known embodiments mentioned above draws , | The hiring is made up of its own in that the rotary pointer

^ "of the temperature meter behind the in front of this pointer with

I playing a curved opening dial

gs, is arranged. This results in considerable parts of the gate,

On the one hand, a much cheaper thermometer measuring mechanism can be used as a result be used, the one on the spiral end of the bimetal spring carries the pointer. Furthermore, this measuring mechanism requires a much smaller bin construction depth, since it is known that between

^; ; The dial and the clockwork do not have too much space between them. On top of this yet, that further development of the! Control of the area of the upper and lower Eandes the arched opening of the dial of the watch ,, behind the "play of the thermometer pointer, for example, can be exploited turskalen for different temperature Λ, up for a scale Fahrenheit and below for a Celsius or Reaumur scale.
