1302828 Fishing reel SHAKESPEARE OF ARKANSAS Inc 19 April 1971 [5 March 1970] 23346/71 Heading A1A [Also in Division F2] A shaft 55 of a fishing reel serves to transmit the cranking torque applied at crank 59 to two driving gears 65 and 70 by means of frictional engagement with drag washers 75, 66, 62. The torque transmitted from shaft 55 to gear 65 and 70 depends on the size of the washers and axial pressure applied on the gears and washers by the control 61 which serves to alter the pressure on the gear arrangement between the spring 82 and web 58. When torque is low, the first gear train operates, the torque being transmitted from crank 59, along shaft 55 to gear 70 by means of drag washers, to a first pinion 30 and finally to the flyer of a spinning reel by means of bearing washer 32 which is firmly held between flyer 26 and first pinion 30 by means of spring 50 and shaft 36. The second pinion 45 slides freely relative to pinion 30, the surface 88 sliding over surface 89, the pinions being held together by springed yoke 95. Above a predetermined torque, washers 66 and 75 are unable to maintain rigid connection between shaft 55 and gear 70 and slipping occurs; however stronger washers 62, 66 maintain rigid connection between shaft 55 and gear 65, and torque is transmitted from crank shaft 55 to gear 65 and so to second pinion 45. Torque is transmitted from pinion 45 to pinion 30 by means of the now engaging clutch surfaces 90, 91, while torque is transferred to flyer 26 from pinion 30 as before. The cam 118 serves to disengage second pinion 45, if desired, by pushing pinion 45 against the resilience of yoke 95 and freeing clutch pawls 40, 46. In a modification the gear supporting shafts may be parallel. In a casting or trolling type embodiment, in which the drive and driven shafts are not parallel to one another, a spring is coiled around the second gear and connects to the first gear. With low torque, the first gear rotates with the second gear, the second gear being held by a spring. With large torques, the coil tends to unwrap, allowing movement of the second gear relative to the first gear. The rig 23, 25 driven by an eccentrically placed pin 94 on foot plate 58 serves to reciprocate line spool 21 and provide level wind. |
