    • A big dial platform scale includes a scale base. A weight sensing apparatus is supported on the base including a weight supporting platform movable relative to the base and a weight sensing mechanism responsive to movement of the platform for moving a beam. A weight indicating apparatus is supported on the base for rotation relative thereto for indicating weight on the platform. A pinion is operatively connected to the weight indicating apparatus for rotating the weight indicating apparatus. A rack is movably supported on the base and operatively engages the pinion for rotating the same. A spring rope is connected between the beam and the rack for transferring movement of the beam to the rack to drive the weight indicating apparatus.
    • 一个大的拨号平台秤包括一个比例基准。 重量检测装置支撑在基座上,包括可相对于基座移动的重量支撑平台和响应于平台移动梁的运动的重量检测机构。 重量指示装置被支撑在基座上以相对于其旋转以指示平台上的重量。 小齿轮可操作地连接到重量指示装置,用于旋转重物指示装置。 机架可移动地支撑在基座上并且可操作地接合小齿轮以使其旋转。 弹簧绳连接在梁和支架之间,用于将梁的移动传递到支架以驱动重量指示装置。

    • A portable weighing scale of reduced size is adapted to permit the weighing of a person while standing with one foot on the platform of the scale, the weight being manifested by an indicator dial which is latched in weight-indicating position and which maintains the weight indication after the person being weighed has stepped off of the platform. A linkage which permits a degree of lost motion is interposed between the platform and the indicator dial, so that the platform can return to its normal position while the indicator dial remains in weight-indicating position, where it remains until reset to its zero position by operation of a latch release. The scale is stable and does not tend to tip over, even when a person's weight is concentrated at one corner of the platform. A one-piece base incorporates, at fixed positions, a plurality of knife edges, formed integrally with the base, which supports the levers and beams making up the linkage between the platform and the indicator dial. The integral construction of the base assures accurate location of the knife edges in relation to each other and achieves maximum accuracy of the scale.
    • 减小尺寸的便携式称重秤适于允许在一只脚站在秤的平台上时对人的称重,该重量由指示盘表示,该指示器表盘被锁定在重量指示位置并且保持重量指示 人称重之后,已经离开了平台。 允许一定程度的运动失速的连杆插入在平台和指示盘之间,使得平台可以在指示盘保持在重量指示位置时返回到其正常位置,在此位置保持直到通过 闩锁释放的操作。 即使一个人的体重集中在平台的一个角落,它的尺度是稳定的,并不倾向于翻倒。 一体式底座在固定位置包括与基座一体形成的多个刀刃,其支撑构成平台和指示盘之间的连杆的杠杆和梁。 基座的整体构造确保刀刃相对于彼此的准确位置,并实现刻度的最大精度。
