Title: Improvements relating to engine units for cycles
Inventor: HUFKENS JEAN
IPC: B62L5/00
Filed: 1952-09-03
Abstract: 721,248. Engine turning gear. ETABLISSEMENTS HUFKENS FRERES SOC. ANON. Sept. 3, 1952, No. 22198/52. Class 7 (5). [Also in Group XXXI] An engine unit for auto-cycles or power assisted cycles comprises an engine 1 which transmits its power through a suitable transmission system, which preferably includes a clutch 5, to a primary shaft 6, means for transmitting the motion of the primary shaft either directly or through step-down gearing 9, 19, 21, 15 to a secondary shaft 11 carrying means e.g. a sprocket 16 for driving the rear wheel 18 of the cycle, means 23 freely rotatable on a pedal crank axle 24 and constantly in connection with one of the gears of the step-down gearing, and a system 26 preferably of the free wheel type on the pedal crank axle for controlling at will, by means of the pedals, the rotation of said freely rotatable means. The engine 1 drives the clutch 5 which is of the multiplate type through its shaft 2, a sprocket 3 and a chain 4. The shaft 6 is hollow and acts as a bearing for one end of a secondary shaft 11 at the other end of which is the sprocket 16. A collar 12 having clutch dogs 13, 14 on its ends is slidably but non- rotatably mounted on the shaft 11 ; in one extreme position it engages dogs 10 on the gear wheel 9 which is fixed to the shaft 6 so that the shafts 6 and 11 rotate at the same speed ; in the other extreme position it engages clutch dogs on the gear wheel 15 which is freely rotatable on the shaft 11 and which constantly engages the gear wheel 21 which is on a layshaft. The gear wheel 21 is made integrally with the gear wheel 19 and with a gear wheel 20 ; the gear wheel 19 is in constant mesh with the gear wheel 9 so that when the collar dogs engage the dogs of the gear wheel 15, the shaft 11 is driven at a reduced speed by the shaft 6. The gear wheel 20 on the layshaft is constantly engaged by the means 23 which is a gear wheel driven from the pedal crank axle 24 by the free wheel 26. Thus when the collar 12 is in a central neutral position with neither of its clutch dogs engaged the engine can be started by rotating the crank axle 24 without at the same time moving the cycle rear wheel. If the collar dogs are engaged with those on the gear wheels 9 or 15 rotation of the crank axle 24 can both rotate the engine for starting and propel the bicycle. If the clutch 5 is held in the disengaged position with the dog clutch engaged rotation of the crank axle 24 propels the bicycle without rotating the engine. The crank axle 24 is also used to operate a brake on the rear wheel by back-pedalling. A ratchet wheel 27 is fixed to the left hand crank 25 so as to be coaxial with the axle 24 and is engaged by a spring-loaded pawl 30 pivotally mounted on an arm 28 which is freely rotatable on the crank axle 24 and which is connected to the brake. Back rotation of the crank axle 24 moves the arm to actuate the brake through the pawl.
