C. Cretors & Company is an American manufacturing company, specializing in popcorn machines and other concessions equipment. It was established in 1885 with the invention of the first large-scale commercial popcorn machine to pop corn in oil. C. Cretors & Co. is in Wood Dale, Illinois and is still owned by the Cretors family.
A hot-air home popcorn maker. A popcorn maker (also called a popcorn popper) is a machine used to pop corn. Since ancient times, popcorn has been a popular snack food, produced through the explosive expansion of kernels of heated corn . [1] Commercial large-scale popcorn machines were invented by Charles Cretors in the late 19th century. Many ...
A recording of a mass blow of traction engine steam whistles. The whistle consists of the following main parts, as seen on the drawing: the whistle bell (1), the steam orifice or aperture (2), and the valve (9). When the lever (10) is actuated (usually via a pull cord), the valve opens and lets the steam escape through the orifice. The steam ...
Popcorn being cooked in a pan. Cretors's invention was the first patented steam-driven machine that popped corn in oil. Previously, vendors popped corn by holding a wire basket over an open flame. At best, the result was hot, dry, and unevenly cooked. Cretors's machine popped corn in a mixture of one-third clarified butter, two-thirds lard, and ...
Collects steam at the top of the boiler (well above the water level) so that it can be fed to the engine via the main steam pipe, or dry pipe, and the regulator/throttle valve. [2] [5] [6]: 211–212 [3]: 26 Air pump / Air compressor Westinghouse pump (US+) Powered by steam, it compresses air for operating the train air brake system.
In the simple case, this can be a relatively simple task as in the internal combustion engine in which the valves always open and close at the same points. This is not the ideal arrangement for a steam engine, though, because greatest power is achieved by keeping the inlet valve open throughout the power stroke (thus having full boiler pressure, minus transmission losses, against the piston ...
The usual locomotive valve gears such as Stephenson, Walschaerts, and Baker valve gear, can be used with either slide valves or piston valves. Where poppet valves are used, a different gear, such as Caprotti valve gear may be used, though standard gears as mentioned above were used as well, by Chapelon and others.
In a steam engine, cutoff is the point in the piston stroke at which the inlet valve is closed. On a steam locomotive, the cutoff is controlled by the reversing gear.. The point at which the inlet valve closes and stops the entry of steam into the cylinder from the boiler plays a crucial role in the control of a steam engine.
