What is it? #69 (Chief stacker)

I haven't seen anyone elses' answers, for fear it would influence my answer. Here's I go:

Is it a mount for things? Like, wireless mic receivers, projectors, amps, ect?

Edit: I was close. :grin:
 
AHH the good old days, remember Schneider parallax adjusting lenses, and of course when some one forgot to lock the slide retainer rings, and during moving all the slides fell out.....
I remember having to do an emergency replacement on a lamp to support a presentation at corporate client literally minutes before the presentation. Get the lamp in and the presenter hands me the carousel only to find out the hard way as he hands it to me that he did not use a retainer ring. Imagine myself and several major corporation executives sitting on the floor trying to put the presentation back together as people are filing in for the meeting.
 
A question:

Can these stackers be flown or are they just designed to be sitting on a surface?
I have one, but sadly only 2 tiers and no top bar...

Thanks
Pete

People employed them in more ways than you can imagine regardless of whether they were designed to be used in those ways or not. "Tommy" used 18 triple stacks for the rear screen projection but mounted the three-way dissolves independently of the stackers to reduce overall height / distance between vertically adjacent stacks.
I recall you were to remove the two adjustable feet from the projectors and use those two points to bolt the projectors to the stacker's shelves. Once firmly attached, you used the stacker's tray adjustments to flawlessly align your images. Do you remember Spindler & Sauppe's precisely mounted pairs of alignment slides with one slide having a red and black checkerboard image and the other bearing a green and black checkerboard? One slide was red where the other was black with the other slide being green where the first slide was black. When installed and flawlessly aligned, they projected a red and green checkerboard with any minor mis-alignments appearing as tiny slivers of amber wherever red and green images were overlapping. As others have posted: You could invest hours precisely tweeking the horizontal, vertical and rotational alignment of your projectors. (and then you progressed on to your next three-stack)
Toodleoo!

Almost always sitting on a surface, often scaffolding, to vertically align the lens center with screen center. A separate scaffold with an airgap of 2-6" between them was for operator(s) who did tray changes and lamp swaps sometimes during shows. Any vibration or disturbance of the projection scaff was seen on the screen and thus avoided.
 
Thanks for the replies. I am wondering if its possible to fly them from a lighting bar as pin-point line-up is not so critical. They would be remotely operated and have full carousel trays. Is the bar across the top designed to take the full weight of the loaded stacker?

Designed for it or not, I've seen, and used, them fitted with one and/or two decent grade C-clamps and a safety or two. Granted this was at least a couple of decades ago in the eighties and early nineties.
