The *slot 22, which is wider than the slot 23, receives the main or body portion ot` thelmnd, and the smaller lelet receives the tongue. lhe shoulders 24., formed by the reduction of the tongue, abut against theI adjacent blade and prevent the `band from slipping through the Slot S23, and the elamping-band is provided with an exteriorindentation 25, whieh embeds the metal in ,the wood. as elearl)x shown iniFig. This construction enables the blades to mounted on an ordinary spring-actuated roller in various positions, so that they will extend radiallytherefrom at derent points. When the spring-actuated roller is rotatedA by the openingr of the screen-door, the blades create a current of air of sufficient strength to prevent the entrance of flies and otherinsects.

lt will be seen that the. fan attachment is exceedingly Simple and inexpensive in oonstrnetion, that it is adapted to be readily applied to a door, and that the spring-actuated roller and the blades will be rapidly rotated when the door is opened and closed. It will also be apparent that the blades, which are easily and cheaply eonstrueted ofa single piece oi' sheet metal, are adapted to be readily clamped on the roller in any desired position.
