Summary
Carbon arc illuminent. This comprises a heavy metal baseplate/sledge which would have slid into grooves in the magic lantern. The lamp is attached to a post through the base plate so that it can be rotated left and right by means of a bolt with a knurled plastic knob and spring which is also mounted to the baseplate. The lamp fits through the post so that a further bolt with a knurled plastic knob and spring mechanism can be used to adjustthe angle of thre illuminant to the baseplate, effectively raising and lowering the light source. The lamp itself is a L shaped construction which mounts via a post into the top of the structure described above. Both legs of the L contain worm screws which connect to the carriages which held the two carbon filments and are also equiped with electrical connection points. The two carriages are controlled by a pair of knurled plastic knobs, the proximal knob controls the far carriage and the distal knob the horizontal top carriage
