Lisle Corporation
Lisle Corporation is an American manufacturer of auto mechanic's specialty tools. It is an independent, private corporation that has been operated in Clarinda, Iowa by members of the Lisle family since its founding in 1903. The company manufactures more than 400 different automotive tools and related items, including the Jeepers Creepers line of mechanic's creepers, and its products are sold at US retailers, including Carquest Auto Parts and Sears. History Lisle was founded in 1903 by C.A. Lisle, originally manufacturing horse-powered well- drilling machines. Lisle's product for the automotive market was an aftermarket master vibrator for the Ford Model T engine, replacing the engine's four trembler coils with a cheaper and more easily adjusted single unit. It then introduced its first tool, an engine valve refacer, a type of lathe for reshaping a cylinder head's valve seats. In the 1930s, the company added a line of magnetic oil pan drain plugs, which were used by th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Poppet Valve
A poppet valve (also called mushroom valve) is a valve typically used to control the timing and quantity of gas or vapor flow into an engine. It consists of a hole or open-ended chamber, usually round or oval in cross-section, and a plug, usually a disk shape on the end of a shaft known as a valve stem. The working end of this plug, the valve face, is typically ground at a 45° bevel to seal against a corresponding valve seat ground into the rim of the chamber being sealed. The shaft travels through a valve guide to maintain its alignment. A pressure differential on either side of the valve can assist or impair its performance. In exhaust applications higher pressure against the valve helps to seal it, and in intake applications lower pressure helps open it. The poppet valve was invented in 1833 by American E.A.G. Young of the New Castle and Frenchtown Turnpike and Railroad Company, Newcastle and Frenchtown Railroad. Young had patented his idea, but the 1836 U.S. Patent Offic ...

Tool Manufacturing Companies Of The United States
A tool is an object that can extend an individual's ability to modify features of the surrounding environment or help them accomplish a particular task. Although many animals use simple tools, only human beings, whose use of stone tools dates back hundreds of millennia, have been observed using tools to make other tools. Early human tools, made of such materials as stone, bone, and wood, were used for preparation of food, hunting, manufacture of weapons, and working of materials to produce clothing and useful artifacts. The development of metalworking made additional types of tools possible. Harnessing energy sources, such as animal power, wind, or steam, allowed increasingly complex tools to produce an even larger range of items, with the Industrial Revolution marking an inflection point in the use of tools. The introduction of widespread automation in the 19th and 20th centuries allowed tools to operate with minimal human supervision, further increasing the productivity of hu ...
