THREE forms of refuse collector are shown at the Fair,
two of them being displayed in the open grounds, where, by the way, a number of vehicles and appliances was either being demonstrated, set to work or being run idly. The steam rollers and the heavy-oil-driven rollers had their engines idling over at low speed hard by an exclusive collection of cranes, light portable railways, pile ,drivers, concrete mixers, diggers, ballast trucks, etc., road making and maintenance being a kind of general title to the whole
display. To revert to refuse collectors, there are evidently two dustless methods of transference from bin to body which have survived from among the many ideas tried in Germany. They are absolutely right there in their efforts to avoid the use of the insanitary dust-cart which still holds its sway in this country. In the first place a strong bin is used not the flimsy things one finds in England, so flimsy that the first impact on a wagon side of a new bin will buckle it so that its lid no longer fits. The bin is
lifted by , two men to an inlet. port on the colleetor, an automatic trap-door to the' port . opening to,pass the .refuse into the wagon and closing on the withdrawal of the empty bin: The contents of the bin are thus "transferred. ,without the spreading of dust or, other evil effects. One system• used on the Mannesmann Mulag and on the N.A.G. refuse collector has a gear-driven elevator which lifts the refuse as it, is received. to the upper chamber, where a rotating shaft having a spiral blade pulls the refuse towards the front. It falls to the sides and on the opening .rif the side flaps at the tip the refuse is discharged.
On the Bussing collector there tire four separate inlet ports which are closed by automatic flaps. The use of four ports effects a partial diotribution of the refuse, and when the wagon is filled to the height. of the ports the wholebody can he rolled over to the other side, this operation being repeated until no more refuse can be introduced. At the rubbish tip, the rear door is opened. and the load discharged by .tipping. This type of body is made by ELerr Bauer, Fahrtzengfabrik, of Cologne, who holds: the patents for Germany. The device is the invention of Rest Neuity, superintendent Of the Bfambui.g cleansing depaitinent.
