"The operation of the condenser is the reverse of that of the air pump, and is a much more simple machine. The air pump, will deprive a vessel of its ordinary quantity of air. The condenser, on the contrary, will double or treble the ordinary quantity of air in a close vessel according to the force employed. This instrument consists of a pump barrel and piston, a, a stop-cock b, and the vessel c furnished with a valve opening downwards. The orifice d is to admit the air, when the piston is drawn up to the top of the barrel." —Comstock, 1850

A belt conveyor consists of two or more pulleys, with a continuous loop of material, the conveyor belt which rotates about them. One or both of the pulleys are powered, moving the belt and the material on the belt forward. The powered pulley is called the drive pulley while the non powered pulley is called the idler. There are two main industrial classes of belt conveyors; Those handling such as those moving boxes along inside a factory and bulk material handling such as those used to transport industrial and agricultural materials. Generally in outdoor locations. Generally companies providing general material handling type belt conveyors do not provide the conveyors for bulk material handling. In addition there are a number of commercial applications for belt conveyors such as those in grocery stores.

"The simplest idea of a crank is that of a handle to a wheel; its action is familiarly illustrated in the process of drawing water from a well: the bent handle attached to the wheel is first pushed out, then pulled in the opposite direction, and thus a continued rotatory motion is produced upon an axle. The application of this principle to the steam engine, and the variations of pressure on the crank of a steam enginre, may be conveniently illustrated by curves." —Comstock, 1850

"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
