Abstract

413,563. Trolly collectors for electric vehicles. AKTIEBOLAGET SVENSKA KULLAGERFABRIKEN, 17, Artillerigatan, Gothenburg, Sweden. Dec. 7, 1933, No. 34509. Convention date, Dec. 17, 1932. [Class 104 (iii).] In a trolly wheel of the type in which the wheel is mounted on an anti-friction bearing and current is conducted from a rotatable contact member to a stationary one, the outer ring 7 of the bearing is fixed to the wheel 1 and is in sliding contact with stationary members 8 pressed inwards by springs 9. The inner ring 3 of the bearing may be made of insulating material. In the form shown in Fig. 4, the annular members 13 rotate with the trolly and contact with stationary members 17 pressed inwards by springs 18.
