1. An [[optical]] [[device]] for making [[pressure volume diagram]]s for high-speed [[engine]]s, involving a light-tight box or camera having at one end a small [[convex]] [[mirror]] reflecting a [[beam]] of [[light]] onto the ground glass or photographic plate at the other end. The mirror is pivoted so that it can be moved so as to copy the motion of the engine [[piston]] on a smaller scale.
