Abstract: 752,540. Turning-gear. BENDIX AVIATION CORPORATION. Oct. 28, 1954, [Nov. 12, 1953], No. 31182/54. Class 7(5) In an engine starter drive comprising a control nut 16 threaded on a screwshaft 5 slidably journalled on a power shaft 1 and connected thereto by an overrunning clutch 4, 6, whereby the axial declutching movement of the screwshaft 5 is limited by an abutment 7 on the shaft 1 against the resistance of a light spring 12 located between the screwshaft 5 and the abutment, the nut 16 being surrounded by a barrel 17 splined to a pinion 14 slidably journalled on the shaft 1 for movement into and out of mesh with a gear 15 of the engine to be started and allowing a limited relative longitudinal displacement of the barrel and pinion whereby the pinion 14 is normally kept in an extended position relative to the barrel 17 by a mesh-enforcing spring 29 mounted between the pinion 14 and the barrel 17, an overload friction clutch 21, 22 is provided between the nut 16 and barrel 17 for transmitting rotary and longitudinal movement from the nut to the barrel. An enlargement 3 on the shaft 1 is formed with the clutch teeth 4 which mesh with the teeth 6 on one end of the hollow screwshaft whilst a thrust washer 11 is positioned between the other end of the screwshaft 5 and the spring 12. The barrel 17 is connected to the nut 16 by the friction clutch 21, 22 which latter is loaded by springs 24 bearing against an adjustable abutment 25; the spring 29, which is located between a thrust washer 27 and a thimble 31 that abuts the nut 16, acts to facilitate indexing in the event of tooth abutment. The reaction of the spring 29 is taken by a lock ring 32 which also forms an abutment for the thrust ring 23 of the friction clutch. The pinion is held in mesh with the engine gear 15 until the engine is self-operative by a spring-loaded detent 33 in the nut 16 cooperating with a notch 35 in the screwshaft, the detent being withdrawn by centrifugal force when the engine is self-operative. In the idle position of the drive the detent 33 coacts with a shoulder 37 to prevent drifting of the pinion toward the gear 15. The abutment 7 arrests the movement of the. nut 16 when the pinion is fully meshed.

Title: Automatic Gas Burning Apparatus
IPC: F23N5/20
Filed: 1978-10-27
Abstract: Automatic domestic cooking ovens are known which have timing equipment which enables the user to preset a starting time and a duration for the cooking operation, a pilot burner within the oven being supplied with gas and ignited electrically at the preset starting time and in turn igniting a principal burner within the oven. To avoid using a mercury vapour flame failure device and a time controlled gas valve in addition to the valve of the flame failure device, a safety valve 11 having a gas inlet port 12 and gas outlet port 13 is used with an electrical air gas mixture igniter 17 and a thermo-electric device 19 arranged to operate in response to combustion of an air gas mixture at the burner 14. A timer device 27 predetermining the onset and duration of an operative state of the igniter 17 causes partial opening of the safety valve 11 initially at the onset of operation of the igniter 17. The safety valve 11 is controlled by the thermo- electric device 19 for a predetermined time starting substantially at or before the onset of partial opening of the safety valve. During control of the safety valve 11 by the thermo-electric device 19 heating of the thermo- electric device 19 by combustion of the air gas mixture enables full opening of the safety valve 11. <IMAGE>
