The Agre-Meter consistsessentially of two 3S-ton hopper bottomsteel bins supported on two steel towersplaced far enough apart to permit thepassage of a motor truck or industrialrailway between them. An overhead service track connects thetowers just below the hoppers and on itthere are installed two measuring hop-pers, each consisting of four compart-ments and connected by a spacer equalto the distance from the center of theindustrial track to the center of the hop-pers. The two are traversed from onehopper to the other by a windlass andendless rope, working them both togetheras a unit. One measuring hopper, set under the. BROOKVILLE TRUCK & TRACTOR CCMPAAiTS GASOLINELOCOMOTIVE. 172 PUBLIC WORKS Vol. 52, No. 9 stone bin, is filled by a single movementof the operators lever and when tra-versed by the windlass to the other hop-per its contents are struck off by a fixedstraight edge that insures the exactquantity of materials in the measuringhopper. When the stone hopper reachesthe center of the industrial track, theScind hopper is automatically placed un-der the discharge gate of the sand binand is filled while the stone hopper dis-charges into the truck or batch traversing mechanism, a single-drum hand winch, is then reversed andthe stone hopper returned to positionunder the stone bin, while the sand hop-per is placed over the truck or industrialtrack and its contents discharged, com-pleting the load of the truck or batchboxes, and so on, the hoppers recipro-cating and charging and delivering eithersand or stone at each movement.
