I consider myself lucky to have found a c.1916-1922 1Kw. Olivette (or Olivette dependant on the book), that is pre-Alzark reflector process. This much less in finding an A-Lamp 100w. version of a box spot c.1910-1916 and it cannot be other than that in dateline - more towards the earlier in both cases by way of tracking the lamps available verses the fixture type for dating.
Yes fortunate to have an example of each, plus some PC fixtures from the era, but I want that Olivette before the 1Kw version came out in matching up to the new 100w box spot. This is more a start of the incandescent era I collect than anything else. Only had 100w lamps, than the 250w globe lamp, the 400w, 1Kw than 2kw Globes followed in the 1910 thru 1916 period in getting up to 1Kw and 400w. The 2Kw lamp came later still.
Such bunch light wash fixtures I think long gone and nobody will ever see them again. Imagine a “bunch light” Olivette concept (it’s a rectangular scoop.) In the case of a bunch light, it’s a bunch of 100w lamps arranged so as to reflect in the fixture in providing a wash. Lots of pictures in Fuch’s 1929 London of the concept including a 12 lamp version for the Munich Electrotechnical exposition in 1882. Footlights, side lights and boarder lights also, but who has room to store them? The really old Olivette is what I want.
The 1916 Chicago Stage Lighting Catalogue (on this site’s WIKI) shows a few versions of it with metal shells in up to 12 lamp in some interesting configurations. The lamps in the photo are not the pinched top nostalgic type either. No table for lamps but by 1916, I would expect up to 150w for an A-19 size.
Getting back to my early Kliegl Olivette, I believe it’s size, shape and style are following the original wood style of construction for the bunch light. Chapter seven of Fuch’s book, P.272 for those following along of the GB. 1929 publication has a small chapter on building your own. My used book even has a pencil lined 13.1/8" measurement in it to the bottom of the PS-52 lamp in the drawing. Suppose they were making an asbestos lined version. “But it should never exceed 18" x 20" in its outside front dimensions, as this is the size of the color frame that accommodates the largest available sheet of gelatin color media.”
For multi-lamp versions, 1" between the globe and gel frame with ventilation roughly. Ventilation with baffles similar to that used on the spotlight in another chapter for a wooden one.
Fuch’s recipie, ½" thick lumber for the sides (Plywood wasn’t yet on the market), and 1" for the top and bottom - Nominal lumber sizing was in place but it was thicker. 1x1 corner cleats to strengthen the frame - though not known if inside or outside the frame - most likely outside and cut to the angle.
The 1" thick lumber at the top and bottom was useful for mounting and for routing or cutting gel frame slits. Shows added lumber in this gel frame slot, or bent steel. Recommends asbestos paper for a liner for the fixture inside both as a heat sink/fire shield and a reflector I think and by today’s standards that cannot be done. On the other hand, McMaster Carr does offer Ceramic sheets that could replace that necessity. 8499K115 in 14"x10"x1/16" thick than could become a design concept for such a fixture.
Later in the chapter, it recommends a ten lamp version if not going 1Kw lamp and more or less follows a German practice for several circuit bunch lights with dipped different color lamps. Such lamps and sockets are mounted to the top and bottom of the fixture by way of 1/2x3" strips of lumber.
Ok, given a base of the Olivette in shape, and the McMaster sheets, that’s a good starting point. Further early lumber thicknesses help also as with how to mount it in other chapters. This I think I can do in 12 lamp bunch light given it's not yet designed for gel sheet maximum size. Now for the tips in doing so or any debate of doing so in adding it to the collection. “Inspired by...” Also for dating it... 1929 is the book in telling how, but this is a pre-1916 type of lighting fixture. Thoughts?
