• describes a method of evenly balancing the power which is transmitted to the two rear axles of a six-wheeler. The shaft which leads from the gearbox, rung through a hollow shaft, the latter carrying the first of the two worms, Whilst the former carries the pins of a differential of the bevel gear type. On these pink are Mounted the usual bevel pinions, which engage in aide wheels, one mounted on the hollow shaft and one on a shaft" that leads to the second Worm.

Relating to Tractors.
T-H-p specification of Lewis Bayliss, Joseph Davey and Spencer Watson, of Clapham, London, No. 280,362,
describes how the frame of a tractor can be altered by adding an extension to it so that more of the load of the trailer can
be brought to bear on the driving wheels. Rigidly connected to the tractor is a frame extending rearwards and carving the turntable of the trailer. The driving' wheels are removed from the rear axle of the tractor and replaced by sprocket wheels. An axle is mounted under the turntable and is connected to the bearing of what was the rear axle of the tractor by means of' radius rods. A chain drive is employed to transmit power from sprockets on the original differential shafts to the driving wheels. The drawing shows the trailer frame ending at the centre of the turntable, but we suppose that the body can be extended farther forward, otherwise there would be nothing gained by the device.
