This artifact was manufactured by Creed & Co. Ltd., a company started by Canadian-born inventor named Frederick George Creed. He was born in Mill Village, Nova Scotia, in 1871. Cet artefact était conçu par la compagnie Creed et Co. Limitée qui était fondée par un inventeur canadien nommer Frederick George Creed. Il est né en Nouvelle-Écosse à Mill Village en 1871.
Function
An electro-magnetic device which functions by forming or breaking an electrical connection by the motion of its armature. Un dispositif électromagnétique qui peut former ou séparer une connexion électrique grâce à la mobilité d'une armature.
Technical
The economized battery consumption greatly improved communications and operation times. This electromagnetic relay has a type E coil, which has a resistance of 100 ohms. It is mounted with a second E type relay on a rectangular base that accommodates two relays. This particular relay is unique in that the relay case has a mechanical adjustment to slightly change the position of the magnet to alter the relay sensitivity. The case would also fit any Creed 27 type relay that uses the "U" shaped magnet. La consommation réduite de la batterie a amélioré le temps d'opération considérablement de ce type d'objet et à augmenter la capacité de communication. Ces genres de relais électromagnétiques ont une bobine de type E avec une résistance de 100 ohms. Il est fixé sur une base rectangulaire avec un deuxième relais du même type. L'artefact est unique, car il peut ajuster la position de l'aimant mécaniquement pour changer la sensibilité du relais. L'étui ou le corps de l'objet peut aussi accueillir n'importe-quel relais fait par Creed de type 27 qui utilise un aimant en forme de "U".
