This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1856 Excerpt: ...of the condensed air in the bottle, will drive up the liquid in a jet. Price, $10.00. revolving jet, $2.00. Air Condensing Apparatus, with 186. Copper Chamber.--(Fig. 186.)--This condensing apparatus consists of a brass condensing pump or syringe, nine inches long, and one and a half inch diameter. A copper chamber or vessel for containing the air, having a stop-cock with screws on the top, with a tube descending nearly to the bottom, and also a stop-cock on the side near the top, there being a tube connected with this aperture descending nearly to the bottom. To the stop-cocks are attached several jets; a straight jet, a compound jet, and a revolving jet. To use this apparatus fill the chamber about half full of water and screw on the stop-cock, connect the condensing pump, and condense the air therein, then turn the stop-cock to confine the air, and remtrving the pump, screw on the straight jet; on turning the cock, the pressure of the air within the chamber will force the water out in a stream with great force. If the compound jet be used, it will produce a great number of streams, and pour out with great beauty. Also the revolving jet will form a pleasing circle in the air, as the water is rapidly forced out. All these jets may also be used on the stop-cock at the side of the chamber. The long brass cylinder, or gun-barrel, represented in the cut, and having a screw fitting the stop-cocks, is designed to illustrate the air gun. To use, screw the barrel to the stop-cock attached to the side of the chamber, having previously condensed sufficient air therein, place a bullet, pea, or cork ball within the barrel, and quickly open the stopcock; the ball will be thrown violently out of the barrel. Price, of the whole apparatus, $12.00. Lever Condenser on Frame...
