Patent number: 11786910Abstract: A meat grinder safety cover attachment for a meat grinder grinding head that prevents an operator of the meat grinder from entering hand or fingers into the inlet throat of the grinder where a turning auger starts the grinding of meat. The grinder safety cover has two functional states: a normally closed state and an actuated open state. Moving from the normally closed state to the actuated open state is initiated by applying a linear force by depressing a slide plunger pin that engages the slide covers covering the grinder head inlet throat. The slide plunger pin and slide covers are configured to convert the linear motion of the slide plunger pin to rotational motion of the slide covers, opening the slide covers and uncovering the inlet throat of the grinder head. Removing the depression force on the slide plunger pin, the torsion spring attached to the slide covers and a return spring in the slide plunger pin then return the safety cover to its normally closed position.Type: GrantFiled: April 27, 2022Date of Patent: October 17, 2023Assignee: BLUE SKY INNOVATION GROUP, INC.Inventors: Gregg M.
