Filling and weighing machine

An apparatus for dispensing predetermined weights of material into containers, said apparatus comprising:

• a pair of pivotable support members, one end of each support member providing a support for a respective container to be filled, the other end of each support member providing a predetermined counterweight to determine the weight of material to be dispensed into said respective container, each said support member being pivotable about an axis between its ends;
• a material feeding chute pivotable about an axis and adapted to dispense material alternately into each said container in such a manner that a material flow, entering said feeding chute impinges on a face of said chute so as to produce no substantial turning moment about the pivot axis of the chute;
• and means for directing said feeding chute from one container to the other when said one container is filled to the predetermined weight;
• said means for directing said feeding chute having a directing member connected to said chute and pivotable about an axis between its ends, two flexible lines, each connected between a respective one of said support members and a respective end of said directing member, said directing member being counterweighted so that its center of gravity passes from one side of its pivoting axis to the other during pivoting;
• whereby each said flexible line causes said directing member to pivot in response to movement of the corresponding support member in only one direction when the respective container is filled to the predetermined weight to thereby direct said feeding chute to the other container.
