I thought that by 1926 the Titanafram had already sunk.

Why, the titanaframs back in my great-great-great-grandpappy's day were nonagonal! And you had to crank 'em by hand! Then they had to go and newfangle 'em up. Any titanafram made after Aught-Eight is a shamafram if'n you ask me.

What a startling contrast to the titanaframs of today.

The two barrels noted at the left side of the photo are a small caliber naval gun and a rangefinder.

Two eyecups in the center of the rangefinder are pointing down at the ground.

The naval gun? Maybe a pedestal mounted, breech loaded 1, 2 or 3 pounder? See the shoulder yoke? The gun is something that might have been obsolete by 1926. Certainly obsolete by WW2. It looks like something that would have been state of the art at the turn of the century but I don't know enough about this stuff to ID it any better.

Makes you wonder what they were keeping under the tarps on the tables. Ammunition? They could have done some serious damage to the "glass table tops" display.

It looks more like a piece of firefighting equipment either for a mobile truck mount or perhaps on a marine fire tugboat. The posters look like they refer to another exhibitor's booth.

So, if I read the patent correctly, the Titanafram is a speaker cone, or diaphragm. Therefore (he said, sucking all the whimsy from the post) only the cone at the center of the display is the actual Titanafram, not the decorative frame or the embossed panel. So it's probably closer in size to a yarmulke. Apparently the significant features of the Titanafram that distinguish it from other speaker cones is the stiffness of the material used (wood!) and the graduated thickness from center to edge. I think it's fair to conclude that it was not a particularly successful design, since last I checked, most speaker cones are still made of treated paper.

[The Hopkins patents were important contributions to loudspeaker design, and eventually licensed to RCA. This was an actual working wired loudspeaker in the photo. They were hanging all over the exhibit hall. Click below to enlarge. - Dave]

I find it interesting that there was enough of a demand for glass funriture tops to allow a business to specialize in them (see display on the right side of the photo).

[Glass tops were widely used in both retailing (on counters) and offices (desks). - Dave]

I am curious what the large caliber barrel on our left is. Is it housewares, per the posters behind it- "The only machine that removes"? I can't make out the pennant's message.

After Googling what the heck a titanafram is, the results page had Shorpy links at the top. I am impressed.
