Device for a spinning reel

Device for a spinning reel designed to give the spool an initial acceleration, said spinning reel comprising a reel frame body (1) with first and second side frames (2, 3), means (4) keeping the side frames together, a cover (6) on the first side frame, a cup (7) covering the cover and the first side frame, a spool (5) journalled in the side frames of the reel frame body, devices for operating the reel, and a spring means (20), characterised in that a flange (8) on the spool (5), adjacent to the first side frame (2) on the reel frame body (1), along its periphery has axially projecting taps (9) with even partition, that the spring means (20) is wound around a first shaft (19) fixed in the cover (6), that the spring means (20) has a first branch (21) projecting parallell to the flange (8) and a second diametrically inwardly bent branch (23), attached to the first shaft (19) and that the first branch (21) in a starting position rests against a lower carrier pin (17) on a lever (16), rotatably attached on a second shaft (15) in the cover (6) and which lever has an upper carrier pin (18), that a thumb key (10), guided sidewardly between the first and second side frames of the reel frame body, has guiding pins (11) sliding between front and rear end positions in slots (12) In the side frames and that the guiding pin (11) at the first side frame is in contact with the upper carrier pin (18) on the lever, that the rear part of the thumb key (10) on its underside has a carrier pin (13) above the taps (9) and directed towards the center shaft of the spool, whereby when the thumb key in a first moment is moved forward against the first carrier pin, the lever (16) rotates around the second shaft (15) so that the lower carrier pin (17) moves the end of the first branch of the spring means (20) in between the taps (9) at the periphery of the flange (8) of the spool and when the thumb key (10) in a second moment is pressed, the carrier pin (13) is likewise moved in between the taps (9) rotating the spool in the reverse direction in a third moment when the thumb key (10) is moved backwards, so that the spring (20) is given desired tension before a fourth moment when the thumb key is released and casting is carried out.
