Abstract: 10,086. MÚgy, L. May 1. Motor road vehicles -The object i s t o enable all the operations of starting, slackening, stopping, backing, and changing from a given rate of speed to a slower rate to be effected by a single working lever or hand-wheel, by which the steering is also effected, while the ratio of the gearing is also automatically adjusted to the resistances encountered. Fig. 2 shows a general plan view of the mechanism, partly in section. From the shaft of the motor 1, motion is transmitted through the first and second intermediate shafts 82, 2 to the third intermediate shaft 39, on which is mounted the chainwheel 40 by which the ordinary balance gear is driven. On t h e hollow shaft 2 are mounted loosely pinions 31, 32, 33, 34 for giving different speeds, any on e o f which can be clutched to the shaft 2, and also a toothed starting and disconnecting wheel 5, which also gears through an idle pinion with a backing toothed wheel 43 similarly mounted on the shaft 39. These wheels are capable of being clutched to the shaft on which the are mounted by friction clutches, which are p u t into or out of action by means of swellings or cones on longitudinally - adjustable rods contained in the shaft. The rods 11, 47 by which the starting and disconnecting wheels a r e clutched or set free are actuated by cams on a shaft 102. This is actuated through a rack and pinion 100 and lever 98<1> from a rocking shaft 99 which is suitably connected to the driver's controlling - handle. The clutches for the pinions 31, 32, 33, 34 are operated by swellings on a rod 30, which is connected by a swivel 81 to a ratchet bar 67. T h i s ratchet bar is capable of being adjusted by mechanism contained in a casing 66 which is both under the control o f t h e driver and of an automatic centrifugal governor or regulator. The action of this regulator is to set the gear at the highest speed which the power of the motor will suffice to maintain, but its effect can always be nullified by the driver. The mechanism for operating the ratchet bar 67 is shown in Figs. 4 and 5. In this, a sliding frame 70, carrying pawls 75, 75<1> is kept reciprocating by a fork 72 worked from a crank on a shaft 85 driven by worm gearing on the first intermediate driving-shaft. The pawls are put into or out of action by spring pins in sliding carriages 69, 69<1>, one or other of which can be stopped by pins 64, 64<1> operated by a shaft 61 and lever 60. The lever 60 can be adjusted by hand, when required, through a cam connection with the rocking shaft 99 ; or it can be adjusted automatically by the centrifugal regulator shown in Fig. 7. The spring-controlled sliding centrifugal weights 52 act through levers 54 and the sliding sleeve 55 on a lever 57. This acts on the lever 60 through a suitable spring connection which permits of the hand adjustment taking place. Fig. 1 shows how the controlling-handle, which acts on the steering- gear when rotated, is arranged so that, by longitudinal movements, it enables the adjustment of the rocking shaft 99 to be effected.
