摘要： A box spring comprises a rectangular base frame, a wire grid, and a plurality of parallel rows of coil springs supporting the grid atop the base frame. Each row of coil springs is made from a single continuous length of wire in which adjacent coils are interconnected by an interconnecting segment of the wire. Each interconnecting segment is in the form of a generally diagonally extending bar having substantially parallel end portions interconnected at the center by an offset section, which offset section is formed by rotating the offset section relative to the parallel end portions while the end portions are restrained against rotation.

摘要： Disclosed is equipment for joining together parallel rows of coiled springs by means of helical wires. Two rows of spaced clamps hold two parallel rows of coiled springs which overlap at the spring ends while the helical wires are wound about the overlap of the springs. The equipment includes an assembly for opening and closing the clamps with minimum wear of equipment components. If substantial wear does occur, the assembly includes means which can be manually adjusted to compensate for the wear. Thus, accurate and precise alignment of the clamps can be easily maintained. The assembly for opening and closing the clamps includes four elements: a cam, an actuator, a cam follower and a connector. The actuator, connected to the cam, is driven by a pneumatic cylinder to move the cam. The connector has the cam follower attached to one end and movable jaw members of the clamps attached to its other end. When the cam moves, the follower follows its movement. This causes the connecting means to move the movable jaw members between open and closed positions.

摘要： A NUMBER OF COIL SPRINGS ARRANGED WITH THEIR AXES HORIZONTAL, ARE REMOVED, WHILE STILL NESTED, FROM A SUPPLY OF NESTED SPRINGS, BY A RECIPROCATING CARRIAGE. A PAIR OF SWINGING FINGERS ON EACH GRIPPER OF AN ALIGNED ROW OF GRIPPERS, GRIPS AND REMOVES ONLY THE END SPRING FROM
THE CARRIAGE AS THE CARRIAGE MOVES PAST EACH GRIPPER. THE ROW OF GRIPPERS ERECTS THE ROW OF SPRINGS AND THEN TRANSFERS THEM TO A CONVENTIONAL SPRING-ROW ASSEMBLING MACHINE.-
