Abstract

523,535. Shot-gun cartridges; paper tubes. BROOKS, P. A., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. Dec. 7, 1938, No. 35713. [Class 9 (i)] Relates to a method of sealing shot-gun cartridges in which a paper or like tube or case is by suitable tools crimped into a pleated cone and turned inwardly whereby the crimped edges are brought together over the shot charge to form a closure with an upstanding bead the usual over-shot card being dispensed with. According to the invention, the case is formed of absorbent paper which, before loading, is dipped or otherwise impregnated with a highmelting point waterproofing wax-like substance. In one form, tubes from which the cases are made are formed of "Kraft" paper coiled on a rotary mandril and bonded by adhesive such as a casein composition. The tubes are then dried, conditioned in a humid atmosphere, and planished. After cutting into lengths, the cases are dipped in paraffin wax excess of which is removed by paraffin and rumbling with sawdust. The dimension of the case is then restored by conditioning to the desired moisture-content in a humid chamber for from four to six weeks. Specification 531,203 is referred to.
