Smith}24/J.17.1.35. 20/25 HP. CHASSIS - PROPELLER SHAFT DAMPER GL.{G. Linnett}722. ----------------------------------------------- Will you please add a note to the arrangement drawing of the Propeller Shaft Damper giving the load at which the flywheels should slip at 5 lbs + 1 - 1 at 17.500 radius, with dry friction surfaces. As designed on N.Sch.3911, no provision has been made for load adjustment, but an examination of the limits on the details concerned G.56821 Spring Guide, G.56941 Rear Flywheel and G.56814 Flanged Hub shows only, a 4 1/2% total range of Spring load, whilst the slipping load limit represents 20% each side of the normal.
