{Pitch line}, or {Pitch circle} (Gearing), an ideal line, in a toothed gear or rack, bearing such a relation to a corresponding line in another gear, with which the former works, that the two lines will have a common velocity as in rolling contact; it usually cuts the teeth at about the middle of their height, and, in a circular gear, is a circle concentric with the axis of the gear; the line, or circle, on which the pitch of teeth is measured.

{Pitch of a roof} (Arch.), the inclination or slope of the sides expressed by the height in parts of the span; as, one half pitch; whole pitch; or by the height in parts of the half span, especially among engineers; or by degrees, as a pitch of 30[deg], of 45[deg], etc.; or by the rise and run, that is, the ratio of the height to the half span; as, a pitch of six rise to ten run.
