| TO HS.{Lord Ernest Hives - Chair} FROM DA.{Bernard Day - Chassis Design} re. HISPANO-SUIZA. ORIGINAL DA{Bernard Day - Chassis Design}1/M1.12.23. 4214 With reference to the particulars of the Hispano-Suiza brakes you have recently sent us we wonder if you could add exact particulars of the cam. We have checked the motions you give and though they are not bad they are a little irregular. We want this information to check the braking forces. For this reason it would be interesting if you could tell us the present position of the cam when brakes are just in engagement. We should also like particulars of the 'servo' mechanism. At present we have only a patent drawing which is not necessarily accurate. We are contemplating making a 'servo' motor of this type for EAC.1. and therefore the information would be valuable at the present minute. DA.{Bernard Day - Chassis Design} | ||
