Description
Elektrischer Schalter mit Zeitmesser, der durch Schließen des Schalters . in Gang gesetzt wird. Elektrische Schalter mit Zeitmesser sind bekannt, bei welchen das Uhrfederwerk bei jedesmaligem Einschalten des Stromes neu aufgezogen wird. Bei diesen Schaltern wirkt auf die Unruhe des Uhrwerkes ein Organ derart ein, daß bei unterbrochenem Strome das Uhrwerk angehalten wird. Ebenso kennt man bei Elektrizitätszählern eine Einrichtung, um die Stromzufuhr zu unterbrechen, sobald das Uhrwerk abgelaufen ist.Electric switch with timer that works by closing the switch . is set in motion. Electric switches with timers are known in which the clockspring mechanism is rewound each time the power is switched on. at These switches act on the restlessness of the clockwork an organ in such a way that at interrupted current the clockwork is stopped. It is also known from electricity meters a device to interrupt the power supply as soon as the clockwork has expired is.
Diese Einrichtung bei einem für vorbestimmte Stromstunden eingestellten Schalter mit Zeitmesser zu verwenden und dabei den Ablauf der Stromstunden anzuzeigen, ist der Zweck der Erfindung. Diese ist in einem Ausführungsbeispiel in der Zeichnung in Seitenansicht und Grundriß, in den Abb. i und a bei geschlossenem und in den Abb. 3 und q. bei unterbrochenem Stromkreise dargestellt..This facility at a set for predetermined hours of electricity To use a switch with a timer and display the elapsed electricity hours, is the purpose of the invention. This is in one embodiment in the drawing in side view and plan, in Figs. i and a with the closed and in the Fig. 3 and q. shown with an interrupted circuit ..
Die ganze Einrichtung ist in einem geschlossenen, nur dem Kontrollbeamten zugänglichen Gehäuse untergebracht. Durch Drehen des Schalters A zwecks Schließens oder Unterbrechung des Stromkreises wird gleichzeitig mittels Exzenters N und federbeeinflußten Stiftes a die Unruhe C des Uhrwerkes freigegeben oder angehalten.The whole facility is in a closed one, only the control officer housed accessible housing. By turning switch A to close or interruption of the circuit is effected simultaneously by means of eccentric N and spring-influenced Pin a, the unrest C of the clockwork is released or stopped.
Das Uhrwerk setzt eine Scheibe E, auf welcher ein Anschlag H ver- und feststellbar angeordnet ist, in gleichmäßige Drehung. Der Anschlag beeinflußt einen Doppelhebel y, welcher den bei Installierung des Kontrollapparates in die Stromschlußlage gebrachten Messerkontakthebel J festhält. Nähert sich der Stromverbrauch der vorbestimmten Stundenzahl, so wird der Hebel 9 gedreht (Abb. 3), wodurch der Hauptkontakt j unterbrochen und durch den Kontakt K ein Widerstandstromkreis, eine akustische oder optische Alarmvorrichtung L eines Nebenstromkreises eingeschaltet wird, so daß der Ablauf der vorbestimmten Stundenzahl rechtzeitig angezeigt wird.The clockwork sets a disc E on which a stop H and is arranged lockable, in uniform rotation. The stroke affects a double lever y, which moves the control device into the Current short position brought blade contact lever J holds. The power consumption approaches the predetermined number of hours, the lever 9 is rotated (Fig. 3), whereby the Main contact j interrupted and through contact K a resistance circuit, a Acoustic or optical alarm device L of a branch circuit switched on so that the lapse of the predetermined number of hours is displayed in time.
Vorteilhaft wird diese Einrichtung mit einem Plombenverschluß versehen in der Art, daß durch eine Plombe 0 ein Doppelhebel B gegen die Wirkung einer Feder festgehalten wird. Sobald die Plombe von unberufener Hand beschädigt wird, schwingt der Doppelhebel B aus, wodurch der Sperrhebel j ebenfalls den Ausschalter freigibt, so daß dieser den Strom unterbricht.This device is advantageously provided with a lead seal in the way that by a seal 0 a double lever B against the action of a spring is being held. As soon as the seal is damaged by an unsolicited hand, it vibrates the double lever B off, whereby the locking lever j also releases the off switch, so that this interrupts the current.
Zur weiteren Erläuterung der in der Zeichnung ersichtlichen Einzelteile sei bemerkt, daß die Scheibe E mittels einer an ihr angebrachten Rolle F die an einer elastischen Scheibe D vorgesehenen Stundenmarken innerhalb von Ausschnitten G der Gehäusevorderwand erscheinen läßt. Die vorteilhaft als Zahnrad ausgebildete Scheibe E kann mittels des verstellbaren Vorgeleges M in jede beliebige Stellung (auf Null z. B.) eingestellt werden.For further explanation of the individual parts shown in the drawing it should be noted that the disk E by means of a roller F attached to it an elastic disc D provided hour markers within cutouts G makes the front wall of the housing appear. The advantageously designed as a gear Disk E can be in any position by means of the adjustable back gear M (to zero for example).
