Such padding is furthermore insulating and far more comfortable than the present horsehair paddings and offers also, as compared with these, the important advantage of a much inferior cost-price. Obviously, applications of the filling material covered by my invention are numerous, since such material can be used not only in constructing the hereinbefore described paddings but also in making resilient "pads, cushions, etc.
Having now particularly ascertained and described the nature of my said invention as well as the manner in which the same is to be 1performed, I declare that What I claim is: esilient cushion padding, comprising a filling, a wrapper enclosing the same, said wrapper and its filling being shaped to form a member of troughor U-section, the opposite arms of which are provided at their inner ends with stitching and at their'frec outer edges with flaps; and a flexible outer envelope enclosing said wrapper and having its edges folded over said flaps.
In testimony whereof I afiix my signature.
