Thanks Linda. You'd think there'd be a lot out there, but not with the 4" fitter--most have a long skinny neck or a small hole with a lip on it. I found two on ebay that might fit.

Did somebody say 1970? :) Anyway, this might be as close as I can get. The original design was a bit more subdued but this is the shape as far as I can recall.

Hope this helps....it helps to be specific..."replacement glass lamp shade with 4 inch fitter"

Thanks again, Linda--I looked through them and they won't quite work. I could get the tulipy ones on the lamp but they wouldn't have room for the three bulbs. The saucer-shaped shades above are 16-18" wide and quite flat, like the original shade. I suppose tall people would be looking right at the bulbs and dead bugs but I don't care what tall people see anymore!

In the "neckless" category, however, there are some globes that might work. A ball wouldn't be too weird would it? Oh. Yeah it would be weird because I wouldn't be able to get any BULBS installed. They have to be screwed in after the shade is on. Darn.

Maybe I should just buy the groovy starburst shade. :/

I doubt this lamp as is would pass muster at UL. Notice the bare electrical strips on the backs of the lamp sockets. These can be easily touched by fingers. The original fitter (shade) must have been more bowl shaped than saucer shaped to shield the bare electrical strips from errant fingers.

Techically, what you're probably looking for is called a "diffuser", or only slightly less properly a "bowl". You will find diffusers listed in the Product Category list on the site that Lindac92 linked to. The hardest part will be finding one that fits that four inch fitter. You'll probably end up having to Google "floor lamp diffuser" or "floor lamp bowl", add either "antique" or "glass" and/or "4 inch fitter" if you're so inclined, and you will find them.

I've never actually seen that kind of fitter base, but I can easily imagine that they were made that way for some reason (obscure to me) and that someone, somewhere still makes diffusers of that size.

I'd date a floor lamp using this kind of diffuser between 1920 and 1950. I'd expect the diffuser to typically surround a single Mogul Base bulb. The lamps would typically also have a set of three smaller, (standard base) bulbs beneath, on arms which would place the bulbs outside the lower part of the diffuser, with a small switch that would light one, two, or all three bulbs at a time. A large fabric shade, wire framed, would rest on the upper edge of the diffuser.

Techically there is a rather different shape for what's called a torchiere shade, glass not fabric, and not intended to have a fabric shade at all. That could very well be what you have there, but the second picture, the decorated bowl, that you attached would probably want to be deep enough that the bulbs were not higher than the edge, something perhaps as hard to find as that four inch fitter hole.

Good luck!

Thanks, CG--a few more search terms are always good to have! It's definitely not the standard torchiere plan.

Jem, now I'm looking at those metal thingies and wondering about safety. The one pictured has lost the screw that secures it to the fixture. The white platform that supports the bulbs is metal and if those metal tabs were hot, the entire lamp would be. Perhaps they are just a ground? They are UL listed! :)

Y'know, I simply have no idea what that is you've got there in the pic above, that base for the sockets...

I kept looking after I posted on Tuesday, and the only 4 inch fitter glass shades I found were identified as "Gas Lamp Shades," every last one of them, no matter which antique lamp parts dealer was selling them.

None of your pics show anything related by design, structure, or age, to a lamp made in the gas lamp period, which here in the US was roughly between 1820 and 1890. Everything about your lamp is newer than that.

Equally problematic is that on one of the antique lamp parts supplier sites (I don't remember which one, sorry) the descriptions were very clear that the interior diameter of the so-called 4 inch fitter shades was NOT a full four inches, more like 3-7/8 inches, so if that whateveritis holding your sockets really is a full four inches, none of the replacement gas lamp shades currently available, and there are lots of them, are going to fit.

So, although you can Google around for 4 inch Gas Lamp Shades, measure that base carefully before you spend any serious money on a shade that might not fit.

I found a lamp with what looks like the same shade/bulb setup offered on eBay.

https://www.ebay.com/itm/VTG-Brass-Torchiere-Floor-Lamp-Reverse-Painted-Glass-Shade-3-Socket-Ferns/322554740139?_trksid=p2485497.m4902.l9144

This is a top view of the ebay lamp showing how the shade just drops down on the lamp's lip. The narrower gas style shades won't work if you want to get three bulbs in there. It's not a terrible reading light.

I have also found that exact fern-themed shade (or a darn good replica) available from a replacement glass shade store online. I forgot which one it was...I didn't like the shade enough to spend that much on it so I didn't save it, but maybe I should rethink that.

There's always the ugly truth that I could get another nice vintage floor lamp WITH a shade for less than the price of a replacement shade for this thing, but that's not nearly as fun!

Yep, there it is. Good find, and it looks like Lindac92 pretty much nailed the date, too.

And it's true, replacement shades, regardless of period, tend to be expensive...

Those straps you spoke of... I suspect their purpose is merely to hold the socket body, which is probably a non-conductive plastic of some sort, on that white platform. I doubt very much that the metal straps have any part in conducting electrical current. That's what insulated wires are for. Could they act as a ground? Technically yes, but only to electrically bind all the metal pieces of the lamp together so that in the event there was a short circuit, probably caused by an insulation failure, the rogue current would be directed to the ground wire, which is always Green and which leads directly to the round pin of a three wire plug. I'm betting the lamp doesn't have a three-prong plug, or a three-wire cord.

Regardless, if you're worried about it, get it checked out by someone who knows. Could be an electrician, but if you have a lamp repair shop anywhere nearby, take it there, have them address your electrical concerns and ask them to replace that missing screw (or whatever) while you're at it so that the bulb will be stable when you have it all together again, ready to use.

Maybe you found this one? It's certainly pricey enough.

Yes, that's it. I did later find the same thing at another lamp parts store for about $50 which is a bit more reasonable. It's just a touch too freewheelin' for a fairly stodgy lamp though.

I'm starting to think that this is not a standard type of lamp that I'm going to find a large selection of shades for once I figure out the right names! I might just macguyver a harp onto it and get a silk shade for it. Less mess when I knock it over as a bonus...

I've never seen macguyver used as a verb before, but I love it! Now, just between you and me, our hero did not have the letter u in his name (Yes, I had to look it up.), but this way at least you'll never get sued for copyright violations.

Ahhh well, I never could force myself to watch it....

That isn't a bad idea at all! I do like the three bulbs hanging off the edge though--it makes for a decent reading lamp.

I was able to attach a harp with some rare earth magnets I had around, after screwing down the loose sockets. These particular magnets have holes in them so I shoved the harp ends into stacks of magnets. I really do love magnets.

So for now, the lamp has a non-breakable regular old fabric shade that is somewhat stable but I'll still keep my eye out for weird flat glass shades!
