| COPY. X7250 BY.{R.W. Bailey - Chief Engineer} From E.{Mr Elliott - Chief Engineer} E.1/M5.10.29. c. to Sg.{Arthur F. Sidgreaves - MD} c. to Hs.{Lord Ernest Hives - Chair} SS.{S. Smith} RADIATOR SHUTTERS. X.7250 X.5250 X.3499 We send you herewith Lec.2750., shewing a scheme for thermostatically operating the radiator shutters on SS.{S. Smith} A latch is provided for keeping the shutters open when required, say for using the starting handle, or should the bellows fail. Mr. Royce would like you to produce a scheme on these lines for the 20 HP. chassis, using a bellows of 1 1/4" outside diameter, instead of 2", and a 2 bolter instead of a 4 bolter flange on the top water pipe connections. It should be remarked that in this scheme Lec.2750 the upper screwed coupling for the flexible water joint between the head and the radiator has been deleted for the sake of simplicity and weight saving. It is intended that the aluminium connection shewn shall be pulled off the short studs in the flange joining to the radiator, utilising the flexibility of the rubber joint when it is required to dismantle this connection for removing the cylinder head.
