"The Danglish apparatus consists of the following parts: 1st, a generator A, in which carbonic acid is evolved from chalk by sulphuric or hydrochloric acid; 2nd, a gas-holder, in which the carbonic acid is stored for use after being purified in passing through water; 3rd, an air pump, for pumping carbonic acid from the gas-holder, and forcing it into the water vessel and mixer; 4th, another air-pump, for withdrawing atmospheric air from the mixer before the aerated water is admitted; 5th, a water vessel B, a strong cylinder of copper capable of withstanding a pressure of 100 lbs on the square inch, and of sufficient size to contain water for a full charge of the mixer; attached to this water vessel there are a gauge-glass C, and a pressure gauge D, for indicating the pressure of gas as it is pumped in; 6th, the mixer E, a globular vessel of cast-iron, capable of bearing high pressure, through the center of which an axle runs, fitted with iron kneating arms extending to the circumference of the vessel." — Encyclopedia Britanica, 1893

"The first alteration to be noticed in the double-acting engine is that of the cylinder. To insure its double action, it is necessary to provide, at each end of the cylinder, a means of admission of steam from the boiler, and of escape for the steam to the condenser. Hence the double action, which means that the piston is both raised and depressed by the force of steam. For this purpose, a steam box is fixed to each end of the cylinder, communicating, in the one case with the upper, in the other with the lower, surface of the piston. B is the upper, and and B' the lower, steam box. Each of these boxes is furnished with two valves." —Comstock, 1850

"In the forcing-pump atmospheric pressure plays but a small part. There is no valve in the piston c, but the water raised through the suction-pipe a, and the valve g, is forced by each depression of the piston up through the pipe e e, which is furnished with a valve to prevent the return of the fluid." — Wells, 1857

"In the arrangement of the flattening and annealing ovens numerous improvements have been effected, which have resulted in greatly increased smoothness and uniformity of the glass, and in considerable economy of time and labor in the operations. This shows a section of a flattening (L) and annealing kiln (M) in common use. The split cylinder O is introduced and gradually pushed forward so as to be uniformly heated till it reaches P, the flattening stone or table, mounted on a movable waggon N. On this waggon after it has been flattened it is carried into the annealing arch M, as shown by the dotted outline. Here in a less heat is graually stiffens, till it is ready to be moved by a forked tool to a horizontal position on the bed of the annealing oven." — Encyclopedia Britannica, 1893

"A section of part of a lace machine. E is the cylinder or beam upon which the lace is rolled as made, and upon which the ends of both warp and weft threads are fastened at starting. Beneath are w, w, w, a series of trays or beams, one above the other, containing the reels of the supplies of warp threads; c, c represent the slide bars for the passage of the bobbin b with its thread from k to k, the landing bars, one on each side of the rank of warp threads; s, t are the combs which take it in turns to press together the twistings as they are made. The combs are so regulated that they come away clear from the threads as soon as they have pressed them together and fall into positions ready to perform their pressing operations again." —The Encyclopedia Britannica, 1910

"The simple outline of the atmospheric engine. Its mode of operation is as follows. Steam is admitted from the boiler into the cylinder, through the tube l, by means of a regulating cock, e, which is worked by a handle outside the boiler; the pressure of the atmosphere above the piston being thus balanced by the force of the steam beneath it, the extremity of the lever beam to whch the piston is attached is elevated by proportionate weights, w, attached to the pump-rod, and the piston is drawn to the top of the cylinder, the other extremity of the beam being depressed." —Comstock, 1850

"ABCD is a cylinder of glass 1 foot in diameter and 1 foot high. This cylinder is closed by a glass lid pierced centrically by two openings, each about 20 lines wide. Into the middle opening is cemented a glass tube 2 feet high, to the upper end of which is fitted a torsion head; the separate parts of the head are shown larger at the side of the figure. H is a collar cemented to the glass tube; MO a metal disc, divided on the edge into 360 degrees; this disc is fastened to a tube N, which slips into the collar H. K is a button whose neck turns easily in a hole in MO; to the lower part of the button is fastened a small clamp, which seizes the wire of the balance. I is an arm with a small projecting piece which slips over the edge of the disc MO." — Encyclopedia Britannica, 1893
