The back brakes are internal expand-ing and made of two cast iron shoesoperating against the inside of largediameter drums on the rear hubs, en-tirely cased in and dustproof. The par-allel pinion type of differential is fittedwith six planets and two star front axle is modern, ample, and ofwrought steel. November, 1913 TYPE OF MOTOR FIRE APPARATUS IN BRITISH USE 439. Steering is worm and segment irre-versible, adjustable with ball connectingjoints; all joints are covered with leath-er casings. Turning radius is as smallas possible. Lubrication is entirely automatic thru-out, being pressure feed system on welltested and satisfactory lines. The frame is of channel steel especial-ly strengthened at the points necessary;the underframe carries engine on three-point suspension. The engine is water-cooled and thewheels are of artillery wood or steel forcarrying .34-inch solid rubber tires. Themachine will ascend any ordinary grad-ient on direct drive and will ascend agradient of 1 in 5 on the lower gears. The air-pump charging apparatus isvery new and in duplicate, there beingtwo double-acting cylinders each work-ing independently, and constructed of acapacity capable of obtaining water from26 feet or 27 feet in 20 to 25 air-pump is brought into action by alever from the drivers seat, and on thewater being obtained, t
