Claim 1

Independent Claim 237 words

AN AUTOMATIC SOLDERING MACHINE FOR PRINTED CIRCUIT PANEL ASSEMBLEIS, AND THE LIKE, INCLUDING: A CONTAINER FOR MOLTEN SOLDER HAVING AN OPEN TOP, SOLDER APPLICATOR MEANS HAVING A PAN-LIKE CONFIGURATION WITH A RIMMED UPPER SURFACE AND POSITIONED WITH SAID CONTAINER, A MOLTEN SOLDER RESERVOIR HAVING AN UPPER RIM DEFINING AN OPEN TOP AND POSITIONED WITHIN SAID CONTAINER WITH ITS UPPER RIM IN SUBSTANTIALLY UNIPLANAR RELATIONSHIP WITH THE RIMMED UPPER SURFACE OF SAID APPLICATOR, CONDUIT MEANS EXTENDING BETWEEN SAID RESERVOIR AND SAID SOLDER APPLICATOR MEANS FOR ESTABLISHING A FLUID CONNECTION BETWEEN SAID RESERVOIR AND THE RIMMED UPPER SURFACE OF SAID APPLICATOR, ELEVATOR MEANS FOR SUPPORTING SAID APPLICATOR MEANS AND SAID RESERVOIR WITHIN SAID CONTAINER AND FOR MOVING THE SAME BETWEEN A LOWER POSITION IN WHICH THE TOP OF SAID RESERVOIR AND THE UPPER RIMMED SURFACE OF SAID APPLICATOR ARE BELOW THE NORMAL LEVEL OF MOLTEN SOLDER IN THE CONTAINER AND AN UPPER POSITION IN WHICH THE RIMMED UPPER SURFACE OF SAID APPLICATOR EXTENDS INTO THE PLANE OF SAID OPEN TOP OF SAID CONTAINER, AND A SOLDER DISPLACEMENT UNIT MOUNTED ABOVE SAID CONTAINER AND INCLUDING A DISPLACEMENT ELEMENT IN VERTICAL ALIGNMENT WITH SAID RESERVOIR AND ADAPTED TO EXTEND DOWN INTO THE OPEN TOP OF SAID RESERVOIR AND DISPLACE SOLDER IN SAID RESERVOIR WHEN SAID RESERVOIR IS IN ITS UPPER POSITION AND THEREBY DISPLACE SOLDER UPWARDLY IN THE RIMMED UPPER SURFACE OF SAID SOLDER APPLICATIOR MEANS INTO A SOLDER CONTACT POSITION.

Claim 2

Dependent Claim 237 words

AN AUTOMATIC SOLDERING MACHINE FOR PRINTED CIRCUIT PANEL ASSEMBLEIS, AND THE LIKE, INCLUDING: A CONTAINER FOR MOLTEN SOLDER HAVING AN OPEN TOP, SOLDER APPLICATOR MEANS HAVING A PAN-LIKE CONFIGURATION WITH A RIMMED UPPER SURFACE AND POSITIONED WITH SAID CONTAINER, A MOLTEN SOLDER RESERVOIR HAVING AN UPPER RIM DEFINING AN OPEN TOP AND POSITIONED WITHIN SAID CONTAINER WITH ITS UPPER RIM IN SUBSTANTIALLY UNIPLANAR RELATIONSHIP WITH THE RIMMED UPPER SURFACE OF SAID APPLICATOR, CONDUIT MEANS EXTENDING BETWEEN SAID RESERVOIR AND SAID SOLDER APPLICATOR MEANS FOR ESTABLISHING A FLUID CONNECTION BETWEEN SAID RESERVOIR AND THE RIMMED UPPER SURFACE OF SAID APPLICATOR, ELEVATOR MEANS FOR SUPPORTING SAID APPLICATOR MEANS AND SAID RESERVOIR WITHIN SAID CONTAINER AND FOR MOVING THE SAME BETWEEN A LOWER POSITION IN WHICH THE TOP OF SAID RESERVOIR AND THE UPPER RIMMED SURFACE OF SAID APPLICATOR ARE BELOW THE NORMAL LEVEL OF MOLTEN SOLDER IN THE CONTAINER AND AN UPPER POSITION IN WHICH THE RIMMED UPPER SURFACE OF SAID APPLICATOR EXTENDS INTO THE PLANE OF SAID OPEN TOP OF SAID CONTAINER, AND A SOLDER DISPLACEMENT UNIT MOUNTED ABOVE SAID CONTAINER AND INCLUDING A DISPLACEMENT ELEMENT IN VERTICAL ALIGNMENT WITH SAID RESERVOIR AND ADAPTED TO EXTEND DOWN INTO THE OPEN TOP OF SAID RESERVOIR AND DISPLACE SOLDER IN SAID RESERVOIR WHEN SAID RESERVOIR IS IN ITS UPPER POSITION AND THEREBY DISPLACE SOLDER UPWARDLY IN THE RIMMED UPPER SURFACE OF SAID SOLDER APPLICATIOR MEANS INTO A SOLDER CONTACT POSITION.

Claim 3

Dependent Claim 248 words

A FLUID DISPLACING UNIT INCLUDING: A CYLINDER HAVING A CLOSED UPPER END AND MOVABLE BETWEEN A LOWER POSITION AND AN UPPER POSITION, A PISTON SLIDABLY MOUNTED IN SAID CYLINDER AND MOVABLE THEREWITH AS SAID CYLINDER IS MOVED UPWARDLY, INLET VALVE MEANS MOUNTED ON SAID CYLINDER TO PROVIDE A RESTRICTED AIR PATH TO THE INTERIOR OF SAID CYLINDER SO AS TO PERMIT SAID PISTON TO MOVE DOWNWARDLY IN SAID CYLINDER AT A RELATIVELY SLOW SPEED AFTER SAID CYLINDER HAS BEEN MOVED TO ITS UPPER POSITION, A FLUID DISPLACING PLUNGER MOUNTED ON THE LOWER END OF SAID PISTON TO BE MOVED DOWNWARDLY THEREBY AS SAID PISTON MOVES DOWNWARDLY IN SAID CYLINDER, STATIONARY BRACKET MEANS EXTENDING ACROSS THE PATH OF SAID CYLINDER OVER SAID CLOSED UPPER END THEREOF, AN ELONGATED ROD COUPLED TO SAID PISTON AND EXTENDING UPWARDLY THEREFROM THROUGH THE CLOSED UPPER END OF SAID CYLINDER AND THROUGH SAID BRACKET MEANS IN SLIDABLE RELATIONSHIP WITH SAID CLOSED END AND WITH SAID BRACKET MEANS, STOP MEANS MOUNTED ON THE UPPER END OF SAID ROD TO ENGAGE SAID BRACKET MEANS AND LIMIT THE DOWNWARD MOVEMENT OF SAID FLUID DISPLACING PLUNGER WHEN SAID CYLINDER IS IN ITS UPPER POSITION AND FOR HOLDING SAID PISTON STATIONARY WHEN SAID CYLINDER MOVES TO ITS LOWER POSITION, AND OUTLET VALVE MEANS MOUNTED ON SAID CYLINDER FOR PROVIDING AN EXHAUST PATH FROM THE INTERIOR OF SAID CYLINDER AS SAID CYLINDER MOVES TO ITS LOWER POSITION TO PERMIT SUCH MOTION OF THE CYLINDER PROCEED AT A RELATIVELY RAPID RATE.

Claim 4

Dependent Claim 248 words

A FLUID DISPLACING UNIT INCLUDING: A CYLINDER HAVING A CLOSED UPPER END AND MOVABLE BETWEEN A LOWER POSITION AND AN UPPER POSITION, A PISTON SLIDABLY MOUNTED IN SAID CYLINDER AND MOVABLE THEREWITH AS SAID CYLINDER IS MOVED UPWARDLY, INLET VALVE MEANS MOUNTED ON SAID CYLINDER TO PROVIDE A RESTRICTED AIR PATH TO THE INTERIOR OF SAID CYLINDER SO AS TO PERMIT SAID PISTON TO MOVE DOWNWARDLY IN SAID CYLINDER AT A RELATIVELY SLOW SPEED AFTER SAID CYLINDER HAS BEEN MOVED TO ITS UPPER POSITION, A FLUID DISPLACING PLUNGER MOUNTED ON THE LOWER END OF SAID PISTON TO BE MOVED DOWNWARDLY THEREBY AS SAID PISTON MOVES DOWNWARDLY IN SAID CYLINDER, STATIONARY BRACKET MEANS EXTENDING ACROSS THE PATH OF SAID CYLINDER OVER SAID CLOSED UPPER END THEREOF, AN ELONGATED ROD COUPLED TO SAID PISTON AND EXTENDING UPWARDLY THEREFROM THROUGH THE CLOSED UPPER END OF SAID CYLINDER AND THROUGH SAID BRACKET MEANS IN SLIDABLE RELATIONSHIP WITH SAID CLOSED END AND WITH SAID BRACKET MEANS, STOP MEANS MOUNTED ON THE UPPER END OF SAID ROD TO ENGAGE SAID BRACKET MEANS AND LIMIT THE DOWNWARD MOVEMENT OF SAID FLUID DISPLACING PLUNGER WHEN SAID CYLINDER IS IN ITS UPPER POSITION AND FOR HOLDING SAID PISTON STATIONARY WHEN SAID CYLINDER MOVES TO ITS LOWER POSITION, AND OUTLET VALVE MEANS MOUNTED ON SAID CYLINDER FOR PROVIDING AN EXHAUST PATH FROM THE INTERIOR OF SAID CYLINDER AS SAID CYLINDER MOVES TO ITS LOWER POSITION TO PERMIT SUCH MOTION OF THE CYLINDER PROCEED AT A RELATIVELY RAPID RATE.
