Fluid weight control meter

Claim 1

A DEVICE FOR CONTROLLING THE WEIGHT OF FLUID DISPENSED FROM A FLUID RESERVOIR THROUGH AN ELECTRICALLY CONTROLLED DISPENSING VALVE HAVING A NORMALLY CLOSED POSITION COMPRISING: A SUBSTANTIALLY HORIZONTAL PLATFORM SUITABLE FOR SUPPORT OF A CONTAINER IN POSITION TO RECEIVER SAID FLUID FROM SAID DISPENSING VALVE; FIRST AND SECOND RIGID MEMBERS, SAID FIRST MEMBER BEING STATIONARY, AND SAID SECOND MEMBER BEING HORIZONTALLY DISPLACED FROM SAID FIRST MEMBER AND AFFIXED TO SAID PLATFORM FOR MOVEMENT THEREWITH; A PARALLEL PAIR OF VERTICALLY DISPLACED RIGID CROSSBARS, EXTENDING BETWEEN SAID FIRST AND SECOND MEMBERS, AND PIVOTALLY CONNECTED THERETO, FOR MAINTAINING SAID SECOND MEMBER VERTICAL WHILE PERMITTING MOVEMENT THEREOF WITH SAID PLATFORM; START MEANS, HAVING A NORMALLY DEACTUATED POSITION, MANUALLY OPERABLE TO AN ACTUATING POSITION TO ELECTRICALLY OPEN SAID DISPENSING VALVE, TO MAINTAIN OPEN SAID DISPENSING VALVE ONLY WHILE SAID START MEANS IS IN AN ACTUATING POSITION; A WEIGHT LIMIT SWITCH, AFFIXED TO SAID FIRST MEMBER, HAVING A CONTROL ARM EXTENDING TOWARDS SAID SECOND MEMBER FOR ENGAGEMENT THEREBY AND SUBSEQUENT DOWNWARD DISPLACEMENT THEREWITH TO MECHANICALLY ACTUATE SAID SWITCH AFTER A PREDETERMINED ANGULAR ROTATION OF SAID CONTROL ARM; A RELAY COIL, ELECTRICALLY ACTUATED BY THE START MEANS THROUGH SAID SWITCH, FOR ELECTROMAGNETICALLY MAINTAINING SAID START MEANS IN THE ACTUATING POSITION WHILE SAID SWITCH IS DEACTUATED; ADJUSTABLE SPRING MEANS URGING SAID PLATFORM UPWARDS, INCLUDING MEANS FOR ADJUSTING THE TENSION OF SAID SPRING MEANS TO THEREBY CONTROL THE WEIGHT OF FLUID DISPENSED BEFORE ACTUATION OF SAID SWITCH;

Claim 2

A DEVICE FOR CONTROLLING THE WEIGHT OF FLUID DISPENSED FROM A FLUID RESERVOIR THROUGH AN ELECTRICALLY CONTROLLED DISPENSING VALVE HAVING A NORMALLY CLOSED POSITION COMPRISING: A SUBSTANTIALLY HORIZONTAL PLATFORM SUITABLE FOR SUPPORT OF A CONTAINER IN POSITION TO RECEIVER SAID FLUID FROM SAID DISPENSING VALVE; FIRST AND SECOND RIGID MEMBERS, SAID FIRST MEMBER BEING STATIONARY, AND SAID SECOND MEMBER BEING HORIZONTALLY DISPLACED FROM SAID FIRST MEMBER AND AFFIXED TO SAID PLATFORM FOR MOVEMENT THEREWITH; A PARALLEL PAIR OF VERTICALLY DISPLACED RIGID CROSSBARS, EXTENDING BETWEEN SAID FIRST AND SECOND MEMBERS, AND PIVOTALLY CONNECTED THERETO, FOR MAINTAINING SAID SECOND MEMBER VERTICAL WHILE PERMITTING MOVEMENT THEREOF WITH SAID PLATFORM; START MEANS, HAVING A NORMALLY DEACTUATED POSITION, MANUALLY OPERABLE TO AN ACTUATING POSITION TO ELECTRICALLY OPEN SAID DISPENSING VALVE, TO MAINTAIN OPEN SAID DISPENSING VALVE ONLY WHILE SAID START MEANS IS IN AN ACTUATING POSITION; A WEIGHT LIMIT SWITCH, AFFIXED TO SAID FIRST MEMBER, HAVING A CONTROL ARM EXTENDING TOWARDS SAID SECOND MEMBER FOR ENGAGEMENT THEREBY AND SUBSEQUENT DOWNWARD DISPLACEMENT THEREWITH TO MECHANICALLY ACTUATE SAID SWITCH AFTER A PREDETERMINED ANGULAR ROTATION OF SAID CONTROL ARM; A RELAY COIL, ELECTRICALLY ACTUATED BY THE START MEANS THROUGH SAID SWITCH, FOR ELECTROMAGNETICALLY MAINTAINING SAID START MEANS IN THE ACTUATING POSITION WHILE SAID SWITCH IS DEACTUATED; ADJUSTABLE SPRING MEANS URGING SAID PLATFORM UPWARDS, INCLUDING MEANS FOR ADJUSTING THE TENSION OF SAID SPRING MEANS TO THEREBY CONTROL THE WEIGHT OF FLUID DISPENSED BEFORE ACTUATION OF SAID SWITCH;
