    A lens, a slit--something optical.

    The gentleman on the far right is unconvinced. (They seldom are.)

    Maybe a projector of some kind. Maybe the round housing he has in his left hand houses the light bulb he's got in the other hand. That unit could go in the box and shine divided light up through the square hole to the mirror and lens.

    The device being shown is a Mirror Drum Receiver for very early television. www.earlytelevision.org/jenkins_mirror_drum.html This H&E photo was used in a Popular Mechanics article (July 1928) included on the page linked above. The tube in his hand is a quartz light tube.

    Thanks swanq for identifying the machine and its inventor. I through I recognized him from other photos, but I couldn't place where I saw them. We'll update the catalog record. If anyone can ID the other people in the photo let us know, especially the guy on the far right with the "this television thing will never catch on" look.

    It also seems to be Jenkins in three consecutive photos labeled only apparatus machine by radio. [And here's a fourth and a fifth and a sixth.]
