Device for the study of the composition of movements

In the lower right corner there is a goniometer and the base of a launching device with spring (which is missing) for a small sphere. The goniometer allows measurement of the angle formed by the initial velocity of the ball and the horizontal level. The trajectory of the ball could be compared to the designed curves, in order to confirm that this is a parabola. There are leveling screws. The terms written on the table are in French, so we assume that the unknown manufacturer was located in France.
