Beam shifting mechanism

Claim 1

IN A SCALE DEVICE A BASE, A PAIR OF SPACED APART BEAM SUPPORTING ELEMENTS RIGIDLY CONNECTED WITH SAID BASE AND PROJECTING UPWARDLY THEREFROM, AN ELONGATED GENERALLY HORIZONTALLY ORIENTED BALANCE BEAM POSITIONED BETWEEN SAID SUPPORTING ELEMENTS AND BEING VERTICALLY SHIFTABLE RELATIVE THERETO BETWEEN AN ELEVATED INOPERATIVE POSITION AND A LOWERED OPERATIVE POSITION, SAID BALANCE BEM HAVING A FULCURM ELEMENT CARRIED THEREBY ENGAGEABLE WITH SAID SUPPORTING ELEMENTS WHEN SAID BALANCE BEAM IS IN THE LOWERED OPERATIVE POSITION, AND BEING DISENGAGEABLE FROM SAID SUPPORTING ELEMENTS WHEN SAID BALANCE BEAM IS SHIFTED TO THE INOPERATIVE POSITION, AND A BEAM ELEVATING LEVER POSITIONED BETWEEN AND PIVOTALLY MOUNTED ON SAID SUPPORTING ELEMENTS FOR VERTICAL SWINGING MOVEMENT RELATIVE THERETO ABOUT A SUBSTANTIALLY HORIZONTAL AXIS, SAID LEVER INCLUDING A BEAM ENGAGING PORTION FOR ENGAGING THE BALANCE BEAM DURING UPWARD SWINGING MOVEMENT OF THE LEVER TO SHIFT THE BEAM INTO SAID ELEVATED INOPERATIVE POSITION, AND A HANDLE PORTION CONNECTED TO SAID BEAM ENGAGING PORTION FOR FACILITATING SWINGING MOVEMENT THEREOF.
