Title: Improvements in Change Speed Gear.
Inventor: SOAMES ALFRED
Filed: 1903-10-20
Granted: 1904-10-20
Abstract: 22,690. Soames, A., and Davies, W. Langdon-. Oct. 20. Motor road vehicles.-Change-speed driving-gear especially for motor cars is arranged so that the operating foot-lever first disconnects the motor shaft and then releases any existing gear, thus removing endwise a sliding rod before any change can be effected ; conversely, the motor can only be connected up after the connection is made with any gear. The gear described is of the kind shown in Specification No. 11,147, A.D. 1903, [Abridgment Class Mechanism &c.]. The motor shaft f is connected by a clutch g with a short shaft c which terminates in the gear-wheel e. The wheel e gears with a wheel d on a shaft b. The car-driving shaft a is parallel with the shaft b, and these two shafts carry intermeshing wheels, representing various gears, of which one wheel is fixed and the other loose, the fixed and loose wheels being arranged alternately on each shaft. The first pair 2 are connected by an intermediate wheel 22 for reverse driving. The loose wheels 2, 4 shown can be moved longitudinally to engage with clutches 1 by means of fork arms 10-13 mounted on the shaft p.. The sleeves of the arms 10-13 have slots in which the pins z can engage. The shaft p is operated by the setting-handle x and carries pins z placed in various positions so that only one at a time can enter the slots in the sleeves. The shaft p gears with a parallel sliding shaft o which carries forked arms corresponding in position to the pins z so that only that arm 10-13 is seized by the fork which has the pin z opposite its slot. The shaft o is moved to the engaging position by the spring q, but is moved back by the lever h attached to the foot-lever after the lever h has released the clutch g. Similarly, the spring q moves the gear to engage before the clutch is put into action.
