CAP FOR FLUE-OPENING.

Fill* the Fine and the Proverbial Long-Felt Want as Well. Here ia a very ingenious and useful arrangement, which was recently patented by a Mr. Gustafson, of Nebraska, It Is a cover for the pipe opening of a flue, and is designed to fit so neatly and closely that it will always be In place and prevent gases, smoke, soot or fire coming into the room. The cover Is dish-shaped, and has an angular flat flange,..which rests against the wall, so that the cover closes the pipe opening, and in the center of the cover turns a screw-rod, with a knob on its outer end. On the Inner end of this rod is a nut in a disk, which touches the Inner surface of an expansion cone of sheet Iron. The sides of the cone overlap each other, so that the cone may be readily expanded or contracted by turning the knob on the outer end of the rod.

When, therefore, the cover is adjusted in the pipe opening, a turn or two of the rod fixes it tight in place, where it will remain until it is desired to take it

out This device seems to be a great improvement over the old-style contrivances that have been used for a similar purpose. It is illustrated and described in the Scientific American.
