Abstract: A foldable wire holder for a plastic bag is disclosed to hold the bag in a vertical position with its mouth snagged in a fully open position on a wire framework formed by a horizontally disposed bag holding frame and an upper portion of an upright supporting framework for the bag holding frame. The wire holder is portable and, in one embodiment, may simply be thrust into the ground where it is to be used, for example, to collect leaves, grass clippings, or other discrete matter. The legs of the supporting frame are provided with stub ends and a lateral support member which sets their depth and keeps the bag holding frame in a horizontal plane while the bag is filled. In another embodiment, a foldable base is provided which is a mirror image of the bag holding frame. Angulation of the pivot on the supporting frame, or of the ends of the bag holding frame, is essential to position the bag holding frame in the horizontal position.

Abstract: A fireplace heat exchanger having input means that is directly connected to a blower assembly, air to be heated is drawn in by the blower assembly and forced directly through the input means into a heat reservoir that is suspended directly above or within the flame of the fireplace. The air is heated within the heat reservoir and then forced through an output means that includes a plurality of discharge ports through which the heated air is dispersed into a room. An aesthetically appealing manifold covers those portions of the input and output means that are outside the fireplace. That portion of the manifold that covers the output means includes a corresponding plurality of discharge ports through which the heated air is dispersed. The input and output means slidably fit within the input and output riser tubes so the heat exchanger can be adjusted for fireplaces of various depths. The heat exchanger can be used with fireplaces having a frame with closable doors, wire mesh curtains, or the like.
