Abstract

334,259. Hemmingsen, T. V. June 1, 1929. Starting. - In a two-stroke marine engine started by compressed air, and having three or a multiple of three cylinders 'and having its cranks arranged in three planes, additional valves and valve-actuating mechanism are provided for supplying compressed air to the cylinders, in order to turn the engine backwards into the starting position when it has stopped in a position in which starting air cannot be admitted from the normal starting valves. In the case of an engine which can be started in either direction, compressed air is supplied to individual cylinders through pipes 6 from a valve chest 4 provided with slide valves 3 actuated by two sets of cams f, b on a shaft 1 movable axially by means of linkage 33, 34, 35. The valve chest 4 is supplied with compressed air through pipes 23, 24, 5 and a valve 7 opened by means of a hand lever 10, which has a projection 11 engaging a link 13 connected to a lever 14 provided with an adjustable abutment 16. When the engine has started, the lever 10 is moved forward to the end of the sector 38, and the link 13 is disengaged from the projection 11 by the engagement of a cam surface on the link with a fixed stop 22. For turning the engine backwards into starting position when necessary, valves 28, in a chest 27 connected by pipes 32 to the pipes 6, are actuated by cams 29 on a shaft 30 which rotates with the shaft 1 but does not move axially. Air is supplied to the chest 27 through pipes 23, 25, 26 and a valve 18 opened by backward movement of the hand lever 10.
