Abstract

1,138,050. Brushgear for dynamo-electric machines. R. GALFETTI. 26 Oct., 1967 [13 April, 1967], No. 48734/67. Heading H2A. The top surface of a brush having no pigtail is engaged by a contact element 12 having teeth 22 providing firm engagement. The contact element is pressed down on to the brush by the pressure-arm 8 through a vibrationabsorbing system consisting of a pin 24 lying in a bed 25 of yielding plastics material. The finger 8 may press on a bulbous region of the pin 24 to improve freedom of movement. Alternatively the pressure-finger may be curved. The teeth may be replaced by a wrapping of wire mesh round the contact element.
