Abstract: Improved corners for overhead frames having primary and secondary fasteners that are located within the distal rectangular periphery of alpha oriented overhead frame components so that the width of bundled overhead frames is reduced; protrusions leading to snagging are eliminated; and the preferred, industry-wide, disassembled frame orientation is maintained.

Abstract: An improved numeracy and place-value educational device which accurately displays a range of both whole-number and decimal place-value properties. A conventional counting-wheel odometer comprising a plurality of sequentially numbered counting wheels (10a-10f) and motion transfer components (not shown) is supported by a frame (12). A decimal carrier (20) moves laterally across a portion of the frame (16). The lateral movement allows a decimal point (20?) to precede or follow any numeral in a specific row displayed by the counting wheels (10a-10f). A place value band (18) displays place value names (19a-19f). Its movement, in unison with the decimal carrier (20) and a moveable comma (241, maintains the correct orientation of place-value names (19a-19f) in relation to the decimal point (20?) in unalterable fashion. Force is applied to the motion transfer components which selectively rotate the counting wheels (10a-10f).
