Title: Improvements in starters for engines
IPC: F02N15/06
Filed: 1926-11-16
Abstract: 267,884. Jackson, M. B. March 17. 1926, [Convention date]. Turning-gear.-In an electric or other starter, a starter pinion 4 is moved axially on its shaft 2 into engagement with an engine gear 5 by a pivoted finger 9 engaging the pinion to one side of its axis, rotary movement of the pinion being effected by the finger if the teeth of the pinion clash with those of the gear 5. The finger is moved out of its operative position by the pinion if the latter is rotated in either direction of the gear, and the finger when in an inoperative position has no appreciable tendency to move the pinion axially. As shown, the finger is pivoted at 9b on the arm 6a of a bell-crank lever 6 actuated by a pedal 8, the finger having a lug 9a on each side of the arm 6<a>. The outward move. ment of the finger is limited by a resilient stop consisting of a U-shaped wire spring 21 crossing the gap between the lugs 9<a>, the limbs being coiled around the pivot 9b and secured at their ends to the sides of the finger. The pinion 4 is mounted on threads 3 on the shaft 2 of the motor 1 and has a flange or collar 4a, preferably serrated, for engagement by the teeth 9<d>, 9e of the finger. A spring 19 and a fixed. stop 23 normally hold the lever 6 and finger 9 in the position shown in Fig. 1. On depressing the pedal 8, the finger 9 moves the pinion into mesh with the gear 5. When the engine starts, the pinion 4 is automatically disengaged by the threads 3 and the finger 9 is thrown into the position shown in Fig. 4, in which it has no tendency to move the pinion axially. If the gear 5 turns backwards, the finger 9 is thrown outwards, against the tension of the spring 21, into a position in which it engages the periphery of the collar 4a. The arm 6b of the lever 6 is arranged to close a switch 11 for the starting motor. In a modification, the finger swings inwardly on its pivot to its operative position and is provided at the end remote from its teeth with a weight sufficient to rock the finger to the operative position determined by the resilient stop. Specifications 261,032 and 264,459 are referred to.

Abstract: 1358077 Switches held set and released mechanically HOOVER Ltd 22 June 1971 [25 June 1970] 29267/71 Heading H1N A member 24 must be moved both rectilinearly and pivotally to operate a switch 16. As applied to a drying cabinet or the like the member 24 is moved rectilinearly by closure of a door 10 acting on a slide 28: the member 24 is pivoted to the slide 28 and when it has been shifted to the position shown it can be pivoted by a pushbutton 14 to act on the button 18 of microswitch 16. The member 24 has a notch 50 so that it is latched by and holds in the button 18; the switch 16 is thus held set until the door is opened and member 24 is moved away from the switch and released. In another embodiment (Figs. 3, 4, not shown) the member 24 is replaced by a shaft 124 (Fig. 5) which is pivoted in bearings at 128, 129 and has a cam formation 148 for actuating the switch 16 in one angular and axial position and a projection 125 upon which the push-button 14 acts. End 128 of the shaft 124 is acted on by the door to move the shaft axially against a spring bias (138) while the push-button 14 rotates it in its bearings. The shaft is also formed with a cam groove 152 co-operating with a fixed pin 158 which prevents rotation of the shaft until it is in the correct axial position (door closed) and also causes the shaft to be rotated to the off position when the door is opened by means of a sloping surface 160 and the axial biasing spring (138). Alternatively the spring (138) can be both a compression and a torsion spring to bias the shaft to its inoperative position. The shape of the cam surfaces 148 may be such that the door can be closed to operate the switch after the push-button 14 is depressed or alternatively (Figs. 7-10, not shown) to prevent door closure unless the push-button 14 is released.
