<p>893,886. Centrifugal governors. BAUER G.m.b.H., EUGEN-. Oct. 28, 1959 [Oct. 29, 1958], No. 36535/59. Class 57. [Also in Groups XX and XL (b)] The speed of a cinematorgaph camera motor is adjusted by altering the spring control in a centrifugal governor. The camera motor drives a shaft 71 by means of a pinion 74. Friction members 77, 78 on springs 75, 76 contact a drum 79. The degree of frictional retardation depends upon the position of a bush 80 which is set through a pin 82 by rotating a sector 85 until a ball 89 is in the appropriate slot 90 to 93.</p> |
