Book 3 — Repairing a Broken Fly-Screen Frame
Reading edition
Sheet-Metal Braces Used on a Loose Window-Screen Frame to Make It Rigid
An old broken fly-screen frame was made quite rigid with the use of metal braces, cut as shown and fastened with nails to each corner. The brace was cut from sheet metal, and the edges A and B were cut and bent at right angles to the main part, with their extreme edges bent over the frame. These were sufficient to make the frame as rigid as a new one.
