Description: Rare Antique 1916 Vintage Standard Narragansett Machine Co. Spirometer. From: Catalog of Gymnastic Equipment, Narraganasett Machine Company, 1916, page 152. The wet spirometer is generally admitted to be the only device for measuring lung capacity that will continue to record accurately. There is no rubber reservoir to leak or harden and crack in two or three years; an air cylinder immersed in water never leaks or wears out. The air cylinder is made of sheet zinc, and as it is made on an arbor, they are exactly the same size and capacity and record accurately their cubic contents. This cylinder is carefully balanced by weights that run in the tubes at the sides. The side tubes are polished brass, and one of them is graduated to measure the height, and consequently, the volume contained in the cylinder. One side of the tube is graduated to cubic inches, the other to cubic decimeters. The stopper at the left lets the air out of the cylinder for it to descend, and that at the right has been replaced by a valve to let the water out of the tank. All parts except the brass tubes are finished in white. It has a capacity of 400 cubic inches or 6.5 cubic decimeters (liters). These seem to be very difficult to find. I'm selling this for parts or repair. "AS IS" I would like to restore it myself, but I just don't have the skill or technology to do a good job with it. As you can see, it has holes in the center bladder. It's missing one side counterweight. Missing the blow tube and mouth piece. Will need new wires. One side at the seam is torn on the outside cylinder and is pushed out. This is a wonderful antique and I'm really hope someone can return it to its original condition. If you buy it and restore it, I'd love to see pictures or a video of it. Please ask me any questions before buying or leaving an offer. Don't be afraid to make a reasonable offer.
