Abstract
The invention is a silent chain with a profile capable of corresponding with the profiles of both sprockets and racks. The purpose of the invention is to convert rotational motion to linear motion in a way that is superior to the traditional rack and pinion device by allowing for more surface area contact with the rack through the use of, rather than a pinion, a silent chain that is capable of engaging with a rack. The invented silent chain comprises link plates of a particular shape stacked in alternating rows and joined together by connecting pins in such a way as to be bendable. The link plates are shaped such that the teeth of the link plates are offset when the chain is straightened, which allows the profile of the silent chain to correspond with the profiles of both sprockets and racks.
