    • A proportioning device having two elongated members (12,14) which are uncouplably joined at a pivotable joint (20) which may be at various predetermined positions (18). Both ends of both of the elongated members terminate at pointers (26,28,30,32), and the pointers at at least one pair of corresponding ends are adjustable. By variation of the pivot point (20) and the position of the adjustable pointer (26,28,30,32), it is possible to obtain a wide range of ratios of lengths between the pivotable joint (20) and the pointers (26,28,30,32) at the two ends of the elongated members (12,14). The device can be used to transfer a series of proportioned dimensions from an original object to an image or reproduction.
    • 具有两个细长构件(12,14)的比例装置,其可在可枢转接头(20)处不可分离地接合,所述可枢转接头可处于各种预定位置(18)。 两个细长构件的两端终止在指针(26,28,30,32)处,并且至少一对对应端部上的指针是可调节的。 通过枢转点(20)的变化和可调节指针(26,28,30,32)的位置,可以获得可枢转接头(20)和指针(26)之间的宽度范围的长度比 ,28,30,32)处于细长构件(12,14)的两端。 该装置可用于将一系列比例尺寸从原始对象传送到图像或再现。
