Apparatus for weighing out flowable materials

Claim 1

AN APPARATUS FOR MEASURING OUT BY WEIGHT INDIVIDUAL QUANTITIES OF LOOSE AND FLOWABLE MATERIALS, COMPRISING A SUPPORTING FRAME; A MATERIAL-DISPENSING DEVICE MOUNTED ON THE SUPPORTING FRAME AND ADAPTED TO MEASURE OUT FROM MATERIAL SUPPLIED THERETO A QUANTITY OF MATERIAL OF A WEIGHT BELOW A CHOSEN TARGET WEIGHT; A WEIGHTING DEVICE MOUNTED ON THE SUPPORTING FRAME BELOW THE DISPENSING DEVICE SO AS TO RECEIVE AND WEIGH EACH QUANTITY OF MATERIAL MEASURED OUT BY THE DISPENSING DEVICE THEREBY TO DETERMINE THE WEIGHT DEFICIENCY OF SAID QUANTITY FROM THE TARGET WEIGHT; A ROTARY MEMBER WHICH HAS PROVIDED AROUND ITS PERIPHERY A SERIES OF CHAMBERS FOR MEASURING OUT FROM MATERIAL SUPPLIED THERETO SMALL MAKE-UP QUANTITIES OF MATERIAL AND WHICH IS ARRANGED ON THE SUPPORTING FRAME SO THAT THE CHAMBERS THEREOF CAN DISCHARGE THEIR CONTENTS INTO THE QUANTITY OF MATERIAL WEIGHED BY THE WEIGHING DEVICE; MEANS MOUNTED ABOVE SAID ROTARY MEMBER FOR SUPPLYING MATERIAL TO THE CHAMBERS THEREOF; AND MEANS CONTROLLED BY SAID WEIGHING DEVICE FOR TURNING SAID ROTARY MEMBER THROUGH AN ANNULPAR DISTANCE DEPENDENT ON THE WEIGHT DEFICIENCY DETERMINED BY THE WEIGHING DEVICE SO THAT THE CONTENTS OF AT LEAST ONE OF THE CHAMBERS OF THE ROTARY MEMBER ARE DISCHARGED INTO THE QUANTITY OF MATERIAL WEIGHED BY THE WEIGHING DEVICE TO MAKE THE WEIGHT OF THIS QUANTITY UP TO THE TARGET WEIGHT, THE CHAMBERS BEING FILLED WITH MATERIAL FROM THE MATERIAL-SUPPLY MEANS DURING SUCH TURNING OF THE ROTARY MEMBER WHEREIN THE ROTARY MEMBER IS ARRANGED ON THE SUPPORTING FRAME BENEATH THE WEIGHING DEVICE SO THAT THE CHAMBERS OF THE ROTARY MEMBER AND DISCHARGE THEIR CONTENTS INTO THE QUANTITIES OF MATERIAL WEIGHED BY THE WEIGHING DEVICE AFTER THESE QUANTITIES HAVE BEEN DISCHARGED FROM THE WEIGHING DEVICE.

Claim 2

AN APPARATUS FOR MEASURING OUT BY WEIGHT INDIVIDUAL QUANTITIES OF LOOSE AND FLOWABLE MATERIALS, COMPRISING A SUPPORTING FRAME; A MATERIAL-DISPENSING DEVICE MOUNTED ON THE SUPPORTING FRAME AND ADAPTED TO MEASURE OUT FROM MATERIAL SUPPLIED THERETO A QUANTITY OF MATERIAL OF A WEIGHT BELOW A CHOSEN TARGET WEIGHT; A WEIGHTING DEVICE MOUNTED ON THE SUPPORTING FRAME BELOW THE DISPENSING DEVICE SO AS TO RECEIVE AND WEIGH EACH QUANTITY OF MATERIAL MEASURED OUT BY THE DISPENSING DEVICE THEREBY TO DETERMINE THE WEIGHT DEFICIENCY OF SAID QUANTITY FROM THE TARGET WEIGHT; A ROTARY MEMBER WHICH HAS PROVIDED AROUND ITS PERIPHERY A SERIES OF CHAMBERS FOR MEASURING OUT FROM MATERIAL SUPPLIED THERETO SMALL MAKE-UP QUANTITIES OF MATERIAL AND WHICH IS ARRANGED ON THE SUPPORTING FRAME SO THAT THE CHAMBERS THEREOF CAN DISCHARGE THEIR CONTENTS INTO THE QUANTITY OF MATERIAL WEIGHED BY THE WEIGHING DEVICE; MEANS MOUNTED ABOVE SAID ROTARY MEMBER FOR SUPPLYING MATERIAL TO THE CHAMBERS THEREOF; AND MEANS CONTROLLED BY SAID WEIGHING DEVICE FOR TURNING SAID ROTARY MEMBER THROUGH AN ANNULPAR DISTANCE DEPENDENT ON THE WEIGHT DEFICIENCY DETERMINED BY THE WEIGHING DEVICE SO THAT THE CONTENTS OF AT LEAST ONE OF THE CHAMBERS OF THE ROTARY MEMBER ARE DISCHARGED INTO THE QUANTITY OF MATERIAL WEIGHED BY THE WEIGHING DEVICE TO MAKE THE WEIGHT OF THIS QUANTITY UP TO THE TARGET WEIGHT, THE CHAMBERS BEING FILLED WITH MATERIAL FROM THE MATERIAL-SUPPLY MEANS DURING SUCH TURNING OF THE ROTARY MEMBER WHEREIN THE ROTARY MEMBER IS ARRANGED ON THE SUPPORTING FRAME BENEATH THE WEIGHING DEVICE SO THAT THE CHAMBERS OF THE ROTARY MEMBER AND DISCHARGE THEIR CONTENTS INTO THE QUANTITIES OF MATERIAL WEIGHED BY THE WEIGHING DEVICE AFTER THESE QUANTITIES HAVE BEEN DISCHARGED FROM THE WEIGHING DEVICE.
