Spencer's patent "consists in a spring for spring-beds constructed with a peculiar central bend or bearing-loop, whereby provision is made, when the spring is placed in position in the bed, for the bracing of the centers of the springs against lateral sway or movement much more conveniently and at far less cost than has hitherto been possible."
