| 摘要 | 477,573. Motors operated by variations in atmospheric temperature. REUTTER, J. L. March 12, 1937, No. 7347. Convention date, Feb. 2. Addition to 446,174. [Class 10] [Also in Group XVIII] A clock employing a thermal motor as described in the parent Specification has the clock mechanism arranged in one of the chambers of the motor close to the movable wall 3 which winds up the clock. Connected to the wall 3 which separates chambers 1 and 2 is a chain 8 passing over a pulley 10 and being attached to a pulley 7 which is connected, through ratchet-and-pawl mechanism, to the winding arbor of the clock spring within barrel 6. Movements of wall 3 with changes of temperature thereby wind the spring intermittently. Chamber 1 is sealed by a wall 15 outside which are the hands 12, 16 and the motionwork 18. The drive from the clockwork inside the casing is transmitted by a permanent magnet 20 on the centre wheel coacting with a similar magnet 21 which is frictionally mounted on the minute hand arbor 13. The regulating lever 23 of the balance 22 is adjustable by a link 24 connected to the end 25 of a bellows 26 which is secured fluidtight to the inner face of wall 5. The bellows are connected by holes 28 to the atmosphere ; the end 25 and link 24 are moved to the right by the pressure in casing 1 and to the left by a screw 27 operable from outside the casing. The gas in casing 1 may be nitrogen, hydrogen, methane, or helium in order not to affect the lubricant. | ||||||
