ABSTRACT:
A low-cost, heavy-duty spool construction for holding substantial quantities of wire, comprising a generally cylindrical spool body having open ends, in combination with a pair of substantially identical, conical end flanges provided with annular grooves in their convex surfaces, in which grooves the end edges of the spool body are received. The apex portions of the end flanges have planar sections which are apertured, and a tie bar extends through the apertures to hold the end flanges tightly against the respective ends of the body. The arrangement is such that the end flanges can be assembled to the body with a minimum of time and effort, and with virtually no chance of an incorrect positioning of the relative parts of the device occurring. Following such assembly, the planar sections of the end flanges are maintained under continual tension, with the spool body being held in constant compression, thereby resulting in an especially rugged construction which is capable of withstanding rough handling even over extended periods of use.
