Counterbalance means

Claim 1

A DEVICE OF THE TYPE DESCRIBED INCLUDING: A SUPPORT MEANS; AN ELONGATE WALKING BEAM PIVOTALLY MOUNTED INTERMEDIATE ITS ENDS AT A FIXED POINT ON SAID SUPPORT MEANS FOR RECIPROCATING OSCILLATION ABOUT SUCH FIXED POINT IN A SUBSTANTIALLY VERTICAL PLANE, ONE END OF SAID WALKING BEAM BEING ADAPTED TO BE CONNECTED TO A RECIPROCABLY MOVABLE VERTICAL LOAD; AN AUXILARY BEAM MEMBER PIVOTALLY MOUNTED AT ONE END ON SAID SUPPORT FOR SWINGABLE OSCILLATION IN A SUBSTANTIALLY VERTICAL PLANE ABOUT SUCH PIVOTAL CONNECTION WITH SAID SUPPORT; A CONNECTING LINK MEMBER PIVOTALLY CONNECTED AT ONE END TO THE END OF THE WALKING BEAM OPPOSITE SAID RECIPROCABLY MOVABLE LOAD AND AT ITS OTHER END TO SAID AUXILIARY BEAM ADJACENT ITS OUTER SWINGABLE END, SAID LINK MEMBER CONNECTING SAID ELONGATE WALKING BEAM AND SAID AUXILIARY BEAM PARALLEL TO EACH OTHER, WHEREBY SAID ELONGATE WALKING BEAM IS SWINGABLE ABOUT ITS PIVOTAL MOUNTING INTERMEDIATE ITS ENDS BY SAID AUXILIARY BEAM; A DRIVE SHAFT CARRIED BY SAID SUPPORT AND ROTATABLY MOUNTED THEREON; A CRANK ARM RIGIDLY SECURED TO SAID DRIVE SHAFT AND ROTATABLE THEREWITH; CONNECTING MEANS OPERATIVELY INTERCONNECTING SAID CRANK ARM AND SAID AUXILIARY BEAM, WHEREBYS AID CRANK ARM IS CONNECTED WITH SAID ELONGATE SWINGABLE WALKING BEAM OPPOSITE THE END OF SAID WALKING BEAM TO WHICH SAID LOAD IS ADAPTED TO BE CONNECTED FOR CAUSING RECIPROCATING OSCILLATING MOVEMET OF SAID WALKING BEAM UPON ROTARY MOVEMENT OF SAID CRANK ARM BY SAID DRIVE SHAFT; AND A COUNTERBALANCE WEIGHT MEANS ON SAID CRANK ARM OUTWARDLY OF SAID CRANK ARM FROM SAID DRIVE SHAFT BEYOND THE CONNECTION OF SAID CRANK ARM WITH SAID AXUILIARY BEAM FOR IMPOSING A TORQUE ON SAID DRIVE SHAFT; AND SECOND COUNTERBALANCE WEIGHT MEANS MOUNTED ON SAID AUXILIARY BEAM AT A POINT SPACED OUTWARDLY FROM THE PIVOTAL CONNECTION OF SAID AUXILIARY BEAM ON SAID SUPPORT BEYOND THE CONNECTION OF SAID AUXILIARY BEAM WITH THE CONNECTING LINK MEMBER, SAID SECOND CONTERBALANCE WEIGHT MEANS COACTING WITH SAID FIRST COUNTERBALANCE WEIGHT MEANS ON THE CRANK ARM FOR VARYING THE LOAD APPLIED TO SAID WALKING BEAM.

Claim 2

A DEVICE OF THE TYPE DESCRIBED INCLUDING: A SUPPORT MEANS; AN ELONGATE WALKING BEAM PIVOTALLY MOUNTED INTERMEDIATE ITS ENDS AT A FIXED POINT ON SAID SUPPORT MEANS FOR RECIPROCATING OSCILLATION ABOUT SUCH FIXED POINT IN A SUBSTANTIALLY VERTICAL PLANE, ONE END OF SAID WALKING BEAM BEING ADAPTED TO BE CONNECTED TO A RECIPROCABLY MOVABLE VERTICAL LOAD; AN AUXILARY BEAM MEMBER PIVOTALLY MOUNTED AT ONE END ON SAID SUPPORT FOR SWINGABLE OSCILLATION IN A SUBSTANTIALLY VERTICAL PLANE ABOUT SUCH PIVOTAL CONNECTION WITH SAID SUPPORT; A CONNECTING LINK MEMBER PIVOTALLY CONNECTED AT ONE END TO THE END OF THE WALKING BEAM OPPOSITE SAID RECIPROCABLY MOVABLE LOAD AND AT ITS OTHER END TO SAID AUXILIARY BEAM ADJACENT ITS OUTER SWINGABLE END, SAID LINK MEMBER CONNECTING SAID ELONGATE WALKING BEAM AND SAID AUXILIARY BEAM PARALLEL TO EACH OTHER, WHEREBY SAID ELONGATE WALKING BEAM IS SWINGABLE ABOUT ITS PIVOTAL MOUNTING INTERMEDIATE ITS ENDS BY SAID AUXILIARY BEAM; A DRIVE SHAFT CARRIED BY SAID SUPPORT AND ROTATABLY MOUNTED THEREON; A CRANK ARM RIGIDLY SECURED TO SAID DRIVE SHAFT AND ROTATABLE THEREWITH; CONNECTING MEANS OPERATIVELY INTERCONNECTING SAID CRANK ARM AND SAID AUXILIARY BEAM, WHEREBYS AID CRANK ARM IS CONNECTED WITH SAID ELONGATE SWINGABLE WALKING BEAM OPPOSITE THE END OF SAID WALKING BEAM TO WHICH SAID LOAD IS ADAPTED TO BE CONNECTED FOR CAUSING RECIPROCATING OSCILLATING MOVEMET OF SAID WALKING BEAM UPON ROTARY MOVEMENT OF SAID CRANK ARM BY SAID DRIVE SHAFT; AND A COUNTERBALANCE WEIGHT MEANS ON SAID CRANK ARM OUTWARDLY OF SAID CRANK ARM FROM SAID DRIVE SHAFT BEYOND THE CONNECTION OF SAID CRANK ARM WITH SAID AXUILIARY BEAM FOR IMPOSING A TORQUE ON SAID DRIVE SHAFT; AND SECOND COUNTERBALANCE WEIGHT MEANS MOUNTED ON SAID AUXILIARY BEAM AT A POINT SPACED OUTWARDLY FROM THE PIVOTAL CONNECTION OF SAID AUXILIARY BEAM ON SAID SUPPORT BEYOND THE CONNECTION OF SAID AUXILIARY BEAM WITH THE CONNECTING LINK MEMBER, SAID SECOND CONTERBALANCE WEIGHT MEANS COACTING WITH SAID FIRST COUNTERBALANCE WEIGHT MEANS ON THE CRANK ARM FOR VARYING THE LOAD APPLIED TO SAID WALKING BEAM.
