Patent for a munitions delivery system designed for anti-submarine warfare. Specifically, this devise is a multi-stage explosive that periodically (period of deployment determined by depth measurement) deploys first a primary detonating charge, followed up by the detonation of multiple, smaller charges scattered by the primary explosion, ensuring an area of effect should the primary canister miss it's intended target. The patent notes that should the canister actually make contact with an object on it's bottom facing, all explosives in the canister will be triggered at once.

Patent for fan attachment for sewing machines: "adapted to be readily applied to a machine and capable of family an operator effectively without interfering with the work of the machine" (lines 12-15).
