Variable proportionate beam scale for proportioning baking recipes

A beam scale assembly (20) for proportioning a first component in a first container and a second component in a second container and comprising:

• a balance beam (22) for receiving the containers,
• a pivot assembly (24) being connected to said beam (22) for balancing the components in the containers,
• said balance beam (22) extending between a first end (26) and a second end (28) and having a front side (30) and a rear side (32) and having a center axis (A0) extending from said front side (30) to said rear side (32) and disposed equidistantly between said first and second ends (26, 28) to define a first balancing area (34) disposed between said first end (26) and said center axis (A0) and a second balancing area (36) disposed between said second end (28) and said center axis (A0) for receiving the first and second containers respectively,
• said first balancing area (34) having a first axis (A1) disposed in spaced and parallel relationship to said center axis (A0) to define a first center distance (Cd1) between said first axis (A1) and said center axis (A0),
• said second balancing area (36) having a second axis (A2) disposed in spaced and parallel relationship to said center axis (A0) to define a second center distance (Cd2) between said second axis (A2) and said center axis (A0),
• said second center distance (Cd2) being equal to said first center distance (Cd1),
• a guide rail (42) extending upwardly from said front side (30) of said balance beam (22) and extending transversely to said center axis (A0) between said first and second ends (26, 28),
• a counterweight (44) slidably disposed on said guide rail (42) for moving said counterweight (44) along said guide rail (42) to establish balance between the empty first and second containers about said pivot (48), and
• said counterweight (44) including a counterweight locking mechanism (46) interconnecting said guide rail (42) and said counterweight (44) to prevent movement of said counterweight (44) along said guide rail (42), and
• characterized by a pivot assembly (24) including a pivot (48) extending downwardly from said balance beam (22) to a pivot edge (50) defining a pivot axis (B) and disposed midway between said first and second ends (26, 28) and extending continuously from next adjacent said front side (30) to next adjacent said rear side (32) and movable relative to said center axis (A0) to define a first variable pivot distance (Pd1) between said first axis (A1) and said pivot axis (B) and a second variable pivot distance (Pd2) between said second axis (A2) and said pivot axis (B) and having a cross-section being semi-circular to define a flat surface (52) for supporting said beam (22) and a circular support surface (54) to establish a rocking movement of said beam (22),
• a first pair of retainer walls (38) diverging from one another and extending upwardly from said rear side (32) of said beam (22) and centered in mirrored image relationship on said first axis (A1) for abutting and centering the first container on said first axis (A1) in said first area,
• a second pair of retainer walls (40) diverging from one another and extending upwardly from said rear side (32) of said beam (22) and centered in mirrored image relationship on said second axis (A2) for abutting and centering the first container on said second axis (A2) in said second area,
• said beam (22) defining a pair of a slot guides (56) disposed in spaced and parallel relationship and extending transversely to said center axis (A0),
• said pivot assembly (24) including a pair of guide pins (58) extending upwardly from said pivot (48) and through said slot guides (56) of said beam (22) for moving said pivot (48) along said beam (22) to adjust the position of said pivot axis (B) relative to said center axis (A0) for concurrently and inversely varying said first and second pivot distances (Pd1, Pd2) in response to said repositioning of said pivot axis (B) along said slot guides (56),
• said pivot assembly (24) including a tie-bar (64) in sliding engagement with said beam (22) and being trapezoidal to define a proportioning point (66) at each end and extending outwardly from said slot guides (56) and defining holes (72) with said guide pins (58) extending through said holes (72),
• said pivot assembly (24) including a pivot locking mechanism (74) on each of said guide pins (58) above said tie-bar (64) for clamping said beam (22) between said pivot (48) and said tie-bar (64),
• said beam (22) presenting a proportioning scale (60) disposed between each of said guides (56) and each of said front and rear sides (30, 32), and
• said proportioning scales (60) including a plurality of identical ratios (62) in scale of said first variable pivot distance (Pd1) to said second variable pivot distance (Pd2) and incrementally decreasing in ratio from a one-to-one ratio (68) at 100% to a predetermined lesser ratio (70) for aligning said proportioning point (66) of said tie-bar (64) with said ratios (62) to proportion the first and second components according to said inversely variable first and second pivot distances (Pd1, Pd2) with said one-to-one ratio (68) of 100% aligned with said proportioning point (66) of said tie-bar (64) when said pivot axis (B) is aligned with said center axis (A0).
