Wright Vertical 4

Wright Vertical 4 aircraft engine on display at the Steven F. Udvar-Hazy Center. This particular engine was used on the Wright B-1 seaplane that crashed in 1912. A patch was bolted to the side of the crankcase in an attempt to repair the engine.

Designer	Orville Wright
Major applications	Wright Model A Wright Model B
Number built	around 100^[1]^[2]

The Wright Vertical 4 was an American aircraft engine built by the Wright brothers in the very early years of powered flight. It was a liquid-cooled piston engine with four inline cylinders, mounted vertically. (Earlier Wright engines were mounted horizontally.) It generated about 30–40 horsepower (22–30 kW) from a displacement of 240 cubic inches (3.9 liters) and weighed about 160–180 pounds (73–82 kg). Developed by Orville Wright in 1906, the Vertical 4 was produced by the Wright Company until 1912 and was the most numerous engine they manufactured.^[3]^[4] Around a hundred Vertical 4 engines were built, according to a Wright test foreman.^[1]^[2]

The Vertical 4 powered most Wright aircraft during this period, including the Model A and Model B and variants built for the U.S. Army and Navy.

This engine was also built under license by Bariquand et Marre in France and by Neue Automobil-Gesellschaft in Germany.^[5]^[2]

Hey, it's Mike from SWISCO.com! And today I'm going to show you how to install the 40-189 Automatic Safety Door Closer. For this exercise all you'll need is a power drill and a Philips head screwdriver. Now this adjustable security door closer can be installed on screen doors, storm doors and an interior wood door like we have here today. Now you want to install it on the jamb of your door, and be sure it keep it away from any obstacles that may be around your door. When you decide on where you want to install the closer, note that there's an arrow on the closer And make sure that arrow is pointing toward the door. Grab your pencil and mark your screw hole locations. And then take your drill and drill pilot holes for the screws. I'm using a 3/32" drill bit. Once your pilot holes are drilled, place your door closer on the jamb with the arrow facing toward the door, and fasten your screws. The automatic door closer comes with two rods. The larger rod is the closing rod, and the smaller one is the winding rod. The winding rod is used to add tension to the door closer. Go ahead and screw this in the nearest hole, move it to the left to add tension. And then go ahead and fasten your closing rod. And then slowly let that release on the door, and then remove the winding rod. Now, the last step is going to be to attach your slide to the door. Now, go ahead and put this into position. Make sure the closing ride touches the slide slightly before the screw hole. Grab your pencil. Mark your hole. And then drill your hole and fasten the slide to the door. As always thanks for watching. If you have any questions on the 40-189 Automatic Safety Door Closer or any other hardware please be sure to visit us online at SWISCO.COM/DISCUSSIONS.
