Title: Improvements in and relating to starting mechanism for internal combustion engines
IPC: F02N5/04
Filed: 1937-08-03
Abstract: 500,198. Turning - gear. BRETTELL, F. G. (Eclipse Aviation Corporation) Aug. 3, 1937, No. 21346. [Class 7 (v)] An engine is started by accelerating an inertia member independently of the engine, coupling the inertia member to an auxiliary engine to start the latter and thus to re-energize the inertia member, and then connecting the coupled auxiliary engine and inertia member to the main engine to deliver the energy of the re - energized inertia member thereto. The inertia member or fly-wheel 16 and the auxiliary engine 9 are carried by a sectional housing 6 mounted on the crank-case 4 of the main engine. The fly-wheel is connected to a dog clutch 26, adapted to engage a clutch member 27 on the main engine shaft, through toothed gearing 35, 32, 39, 40, planetary gearing 46, a multiple-disc clutch 20, and a threaded shaft 23. The fly-wheel is set in rotation by means of a shaft 86 driven by a hand crank or other means and connected to the shaft 31 of the fly-wheel through an overrunning clutch 91 and gearing 89, 90, 94, 32, 35. The fly-wheel is then moved axially on its shaft 31, to engage a friction clutch 57 coupling it to the crank-shaft 56 of the engine 9, by means of arms 96 of a shifter yoke 97 on a rock-shaft 98 actuated manually by means of a link 103. The shaft 98 actuates switch means in a casing 101 for switching on the ignition magneto 78 of the engine 9 and for subsequently effecting the engagement of the main starter clutch 26, 27 by means of a solenoid 104, which actuates a rod 106 connected by an arm 108 to a rockshaft 109 engaging a shifter yoke 30a. To delay the actuation of the clutch 26 by the solenoid 104 for an interval sufficient to allow for the starting of the engine 9 and the reacceleration of the fly-wheel, the arrangement shown in Fig. 2 is employed. A second solenoid 113 has a core 114 insulated from a spherical member 115 loosely held by fingers 116 on a rod 117 carrying a dashpot-piston 119 and an insulated contact member 123 adapted to engage contacts 126, 127 in the circuit of the solenoid 104 and a series resistance 153. When the shaft 98 is operated to engage the clutch 57, the circuit of the ignition magneto 78 is closed by a contact member 144 and the circuit of the solenoids 104, 113 by contacts 134, 135 engaging contacts 132, 133. The solenoid 113 raises the contact 123 and thus breaks the circuit of the clutch-engaging solenoid 104; the ball 115 is released from the fingers 116 and the contact 123 restores the circuit of the solenoid 104 after a period depending onthedashpot 118, which has an adjustable, vent screw 121. In a modification, in which the ball connection 115, 116 is omitted and a switch arm breaks the circuit of the solenoid 113 in the upper position of the rod 117, this switch arm is actuated by a third solenoid and by the upper end of the rod. To enable the fly-wheel to be employed without starting the auxiliary engine 9, the switch 133, 135 may be actuated independently of the rock-shaft 98 by means of an arm 160.
