Excerpt from The Textile Industries, Vol. 5: A Practical Guide to Fibres, Yarns and Fabrics in Every Branch of Textile ManufactureThe Tappet System. - Sometimes readers of textile manuals, and enquirers into the subject generally, find themselves confused by the careless manner in which technical terms are employed, Here we have a good instance. Tappet, cam, and wiper says a writer, are names given indiscriminately to those irregular pieces of mechanism to which a rotary motion is given for the purpose of producing, by gliding contact, reciprocating motions in rods and levers. When the rod is to receive a series of lifts, with intervals of rest, the piece is generally called a tappet, but if the motion is continuous, the terms cam and wiper are used.We hardly think the definitions given will altogether correct the tendency of workers, and even writers of textbooks, to employ the terms as fancy dictates, but the writer has described with fair accuracy the mechanism itself and the original applications of the three words.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
