  • Patent number: 4738349
    Abstract: An automatic spring feeding device is shown which uses a three-sided feedbox having a movable bottom panel for urging a series of springs into rotating bundles against a moving platen which forms the fourth side of the feedbox. The platen is grooved with specially shaped grooves which capture individual springs therein under the urging of a magnet on the opposite side of the platen from the springs. The platen is then carried by a continuous drive chain to a spring feed assembly where the springs are loaded one at a time into a channel from which the springs are metered by a solenoid operated release door. The key to handling the springs without tangling them is to wind each end of the spring with a closely wound coil. After the springs are placed upon a conveyor belt, the unwanted closely wound coil or coils may be removed by a suitable shear.
