Abstract

632,827. Signalling movements of animals. VERPLANKE, M. W. June 19, 1947, No. 16164. Convention date, July 2, 1946. [Class 81(ii)] [Also in Group XXXVII] An electric alarm device for parturient animals comprises a contact device adapted to be attached to the animal and to be connected to an electrical signalling means, the contact device being provided with an operating member 4 extending adjacent the vagina of the animal, said member being pivotally mounted on a casing 1 which is attached to the animal and contains a spring 6 which holds the member 4 pressed against the animal. When the member 4 is displaced at the commencement of the birth the resultant movement of the axle 5 to which the members 4 and 7 are secured, closes contacts 9, 10, thus completing the alarm circuit.
