Abstract: A CAGING DEVICE FOR RAPIDLY ACCELERATING A GYRO UP TO AN OPERATING SPEED OR USE, FOR EXAMPLE, IN A FLYING BODY OR A MISSILE, INCLUDES A DRIVING MECHANISM CONTAINED IN A SEPARATE HOUSING ADAPTED TO BE ATTACHED TO THE HOUSING OF THE GYRO. THE DRIVING MECHANISM INCLUDES A PISTON-NOZZLE TUBE WHICH IS SLIDABLE IN A CHAMBER FORMED AS A NOZZLE TUBE WHICH IS SLIDABLE IN A CHAMBER OF THE DRIVE HOUSING. AN ADDITIONAL CHAMBER ALONGSIDE THE PISTON CHAMBER CONTAINS A SOLID CHARGE AND AN IGNITER FUSE. THE CHANGE IS OF A SIZE TO BURN OFF AT A RATE SUFFICIENT TO PROVIDE A HIGH FLOW OF COMPRESSED GASES WHICH ARE PASSED THROUGH AN OPENING BETWEEN THE CHAMBERS INTO THE PISTON CHAMBER WHERE THE GAS INITIALLY ACTS ON THE PISTON TO DISPLACE IT SLIGHTLY IN ORDER TO RELEASE A LOCKING DETENT WHICH PREVENTS RETRACTION OF THE NOZZLE TUBE FROM THE GYRO HOUSING INTO THE NOZZLE TUBE CHAMBER. AT THE INITIAL POSITION OF THE NOZZLE TUBE PISTON, THE END THEREOF EXTENDS INTO THE GYRO CHAMBER AND THROUGH ALIGNED OPENINGS OF TWO GYRO-SUPPORT GIMBALS SO THAT THE GIMBALS ARE LOCKED AGAINST MOVEMENT DURING THE INITIAL START-UP OF THE GYRO. AFTER THE SOLID CHARGE HAS BURNED OFF, THE GAS PRESSURE REDUCES SUFFICIENTLY TO PERMIT A RETURNING SPRING TO ACT ON THE PISTON MEMBER TO PULL THE TUBE PORTION OUT OF THE GIMBALS TO PERMIT THEIR FREE PIVOTAL MOVEMENT.
