Book 3 — Scraper for Tennis Court

A Tennis Court was Smoothed and Leveled by the Use of This Scraper, Made Quickly of Rough Lumber

In order to level and scrape a tennis court, which was in bad condition, the two-man scraper shown in the sketch was made. It is built of rough lumber, and a metal shoe is fixed to the lower edge of the scraping blade at the rear. The bearing at the front is on a flat-bottom sled of wood, and the depth of the cut is regulated by pressure on the handle. The scraping blade is set at an angle, as shown in the smaller sketch. By lifting the handle slightly, the operator is able to deposit dirt in holes so that when the court is rolled they are filled evenly. Where a large number of courts are to be smoothed, the device may be adapted and made large enough to be drawn by a horse.—Edward R. Smith, Walla Walla, Wash.
