Rose and Buell's patent is intended "to provide a coil-spring for beds, car and wagon-seats, chairs, and the like, in a given space, will give more elasticity than the ordinary coil-spring, and is combined with a cavity underneath the spring in the form of a concave, into which the spring may be pressed, the successive coils resting upon the concave when pressed down."
