Title: Change speed gear for cycles
IPC: B62M9/12
Filed: 1946-08-16
Abstract: 620,708. Change-speed, chain gearing. BOERIS, A. Aug. 16, 1946, No. 24513. [Class 80 (ii)] In a change-speed gear for cycles actuated by shifting the chain and a displacement of the wheel hub spindle, the variation in transmission ratio is obtained by means of a selector which shifts the chain into the plane of the appropriate gear sprocket, and by displacement of the wheel hub spindle parallel to itself on racks 29 secured to the cycle frame. A tubular rod 14 carries an arm 15 and chain engaging fork 16 at its lower end whilst its upper end has a pin 17 engaged in a helical groove 18 cut in a tubular support 1 secured to the tube T of a bicycle. A roller. mounted on a pin 13 fixed in the bore 13<1> in the rod 14 engages a helical groove 11 formed in a member 8 which is rotatably secured to support 1 by a tooth 9 engaging a groove therein. The member 8 carries an actuating lever 10 whose operative position may be felt by the engagement of a spring pressed ball 7 with a groove in the member 8. Within the tubular rod 14 is mounted a rod 19 for displacing the spindle in the forks F and locking it thereto. The upper end of rod 19 is hexagonal in form and has keyed thereto the hub 201 of a shifting fever 211. The end of the rod carries a screw 36 the head 37 of which carries a spring 39 bearing against the end of rod 19 for adjustment purposes. The lower end of rod 19 carries an eccentric 20 which engages a hole 23 in the head 24 of a pull rod 25 extending through the hollow spindle 27. The rod 19 and head 24 are connected by a nut 21, a nut 26 being secured to the opposite end of rod 25. The spindle 27 has toothed wheels 28 secured to its ends which engage racks 29 on the cycle frame. In operation, rotation of lever 21<1> through 180 degrees causes like rotation of rod 19 and eccentric 20 thereby producing axial movement of rod 25 and releasing the spindle for movement along the racks 29. Movement of lever 10 to a given gear position causes axial movement of rods 14, 19, by virtue of the engagement of the roller with groove 11, and rotation of rod 14 due to the engagement of pin 17 with groove 18. This shifts the chain and spindle to an appropriate position, and the spindle may be again locked in the forks by rotation of lever 21<1>. In a modification means are provided to permit ease of removal of the driving wheel without removal of the means for actuating the change speed gear. Rollers mounted on the spindle 27 may engage slots in the frame, for supporting the load, whilst the sprockets 28 merely serve for guiding the spindle in a parallel direction.
