Patent number: 10935356Abstract: A discrete empty casing feeder for a cartridge reloader is controlled electronically by a control module. Empty casings are loaded on top of each other in a conventional feeder tube and are gravity fed through the feeder tube onto an upper rotating carousel. The discrete empty casing drops into a cylinder in the upper carousel and the carousel and casing rotate until the casing reaches a hole in the floor under the upper carousel. The discrete empty casing drops onto a solenoid lever in a tube. When the typical lower turret is raised mechanically, a sensor detects that the lower turret and push ram are in the correct position. The trap lever opens and drops the empty shell casing into a slot in the front of the push ram. The push ram then pushes the correctly oriented discrete casing onto the conventional turret. As the shell casings go through a normal reloading cycle, a fully loaded cartridge is ejected from the lower turret and the entire process begins again.Type: GrantFiled: April 17, 2020Date of Patent: March 2, 2021Inventor: Daniel Steven
