clamped in this position. The prism reaches only over one half of the opening E to which the eye is applied. The object at A is seen with the naked eye through the other half of the opening at E whilst the drawing surface at B is seen by the rays proceeding from it and then reflected at the mirror and prism.
Since it is essential that the object and drawing surface should be equally bright the apparatus is provided with twro neutral tint glasses, either or both of which may be placed in front of the prism, on the side facing the mirror, to moderate the brightness of the drawing surfaces, whilst three moderating glasses Nos. I, II, III serve to moderate the brightness of the object. These moderating glasses should be placed upon the intermediate adapter ring between the stand and the apparatus or, in the event of a lens being used, they may be placed on the latter.
To be able to employ small magnifications, say 2-, 3-, 4- and 5-fold, the apparatus is provided with four appropriately mounted bi-convex lenses having focal lengths of 150, 110, 75 and 50, which are placed on the intermediate adapter below the prism. These same lenses will furnish numerically analogous minifications if object and drawing surface be interchanged.
The apparatus is available for drawing horizontal as well as vertical objects. For this purpose the entire apparatus should be turned through an angle of 90°.
