Abstract
Abstract A structure is attached to a conventional mower or other machine that normally discharges a stream of high-velocity air with entrained particles such as grass clippings or chopped leaves. This structure supports a standard refuse bag on a frame receivable into the mouth of the bag, which is secured to the frame by a constricting tie surrounding the bag and the frame periphery. The bag is additionally supported on the inside by a normally horizontal member secured to the frame.

Total Claims: 4
Claim 1
Independent Claim
225 words
Apparatus for collecting in a fluid impervious bag the debris discharged by a rotary lawn mower housing through the discharge opening of said mower housing, comprising: a frame panel having a first opening of substantially the same configuration as said discharge opening of said mower housing, a second larger opening, and a groove extending around the entire periphery of said paNel, the length of the periphery of said panel being substantially equal to the circumference of the opening of said bag; mounting means securing said panel to said mower housing in a vertical position with said first opening of said panel in alignment with and immediately adjacent to said discharge opening of said mower housing; a screen secured to said panel and covering said second opening therein; a U-shaped support member secured at its ends to said frame panel adjacent the upper edge thereof and extending outwardly from said panel in a generally horizontal plane perpendicular thereto, said support member being adapted to be received in said fluid impervious bag, the width and length of said support member being substantially equal to the width and depth, respectively, of said bag; and a constricting tie adapted to encircle said bag when the open end thereof has been positioned over said panel, said tie forceably engaging the material of said bag in said groove of said panel.
