A POWER-OPERATED moving-floor body, which has LA been subjected to Strenuous tests over the past 12 months, has now been made available by Bromilow and Edwards, Ltd., Foundry Street, Bolton, Lancs. Having acquired the Principality moving floor with handoperated mechanism, this concern set out to provide for power operation and the result is shown in accompanying illustrations.
The drive is taken from the orthodox type of gearbox power take-off, from which an extension shaft takes it to a countershaft, through sprockets and chains. Mounted on this countershaft is a bevel-gear assembly, provided with two cone clutches—one to engage the drive for. forward motion of the belt and the other to transmit the drive, through suitable mechanism, to a roller at the rear of the body, giving ,a rearward movement to the belt such as is necessary when discharging a load.
The long handle, for operating the ,clutch, is spring loaded, automatically to bring it into a neutral position when released. Control is thus extremely simple, in that when the clutch handle is pushed, the forward-motion, clutch is brought into engagement, and when the handle is pulled, the second clutch comes into operation to reverse the direction of travel of the belt.
Not being an endless belt, a suitable indicator is provided to sliciw when the belt is wound fully on to its respective rollers. The simplicity of the mechanism and its straightfora-ss-d layout provide for efficient results, combined with the need for a minimum of attention in service. The present body is mounted on an Albion chassis, but given a suitable power take-off, it can be fitted on any type of normal chassis.
