A NOVEL AIR Cushion.—A successful test of ihe Ellithorpe air cushion for elevators was made recently in a New York dry-goods house. One of the largest Otis elevators, weighing 2300 pounds, equipped with plate glass mirrors and fragile electric light globes, and loaded with baskets of eggs and with glassware filled with water, was cut loose from the top floor and allowed to fall to the bottom of the shaft. It shot down eighty feet in about two seconds. The “cushion,” which stands seventeen and one-half feet high from the bottom of the shaft, and is constructed ol wood and glass so as to be air-tight, received the elevator with so little shock that not even an was broken, nor a drop of water spilled. The test was considered a complete success. The force of the compressed air of the “ cushion ” gently pushed the elevator up again about four inches, when it descended again to its place without jar. The force of the descent was estimated at the top of the “ cushion ” as indicating 60,000 pounds.
