This invention relates to a simple and convenient form of plumb and level, which may also be adapted for use in laying off bevels and miters, for cutting rafters, braces, inclines, &c. The invention consists in a plumb-level having certain peculiarities of construction, as herein after described and claimed, reference being made to the accompanying drawings, in which Figure 1 is a perspective view, partly, in section, of my improved plumb and level as constructed for indicating angles, whereby it is adapted for laying off bevels, &c. Fig. 2 is a view of the pendulum having an index or pointer.
