Peltier's process of striating the glass was definitely outlined in patent 1,927,650. Which would not be limited to only feathered type slags in my opinion, but many more striated possibilities with a few adjustments.

Mon, yes you are correct. Figure 2 is the top view of figure 1. Here are the other drawings of the patent. Galen, yes the apparatus is inside of the furnace.

Closer view of Akro's injectors.

Interesting that a patent no. isn't mentioned in the case text for Master Marble's machine. Unless i missed it.

According to the Akro vs. Master case text: Akro injected two seperate streams that consolidated into one stream w/ colored glass on the interior only and clear glass surrounding the colored. Master's machine only dumped colored glass into a pool of clear glass without control of the colored glass and without a separate pot of colored glass. Also, Master's colored glass was not wholly within the clear glass and there are no separate streams of clear or colored glass.

Thank you Steph. I think i see it now in patent 1,529,947. Early in the reading it states: -"any desired color may be injected into the center of the flowing glass stream" -FREESE patent US1529947

Another patent related to the case by inventor John F. Early for Akro Agate is US patent 1,880,916: filing date 5/25/1928, publication date 10/4/1932. Not sure how to post a link.

Did some digging. The Early patent, No. 1,761,623 - filing date 3/22/1926 and publication date 6/3/1930 was the patent that Master Marble Co. was accused of infringing upon. Could that possibly be the sparkler maker?

Looking for some good information on production start dates for Akro Sparkler marbles. (or at least some good discussion). Particularly interested in when the injection method of marble manufacture (if thats a proper term) was introduced at Akro. Patent info, box info and any insight into these marbles is greatly appreciated.

Yes, very informative. Just what i was looking for, thanks.

Pelt on both.

Looking for a good technical definition of what makes a machine-made marble a swirl.

Any peltier multi-color without white is tougher to find. These are very under-rated in my opinion and don't have a name. Some can be swirly....

Q: Do you think it was meant to be this way?? A: Not sure. Wish i knew the answer. Q: If there are only 3, who named them? A: I believe a peltier collector named Bruce Lockheart (r.i.p) named it that if i'm not mistaken. And he sold his to Clyde T. if im not mistaken on that as well. It was just a name used between the people who had them, whether the name sticks or not is up to the marble community. It's probably safer to call it a green lantern variation so that future collectors don't get confused in my opinion. Some of the names in Chuck's photo are newer, the ones he made up are phantom superman and sun dragon, not sure about sellers dream. The "clear superman" is usually referred to as a "fruit cocktail" although clear superman sounds much better. The rest i believe to be older names.

I have one of the green goblins, it's the green lantern's wild brother. Clyde T. (r.i.p) and Chuck G. also have one. But where there is 3 there may be more.

1 vote for kokomo. The one on the left is a known kokomo shooter (13/16").

No wonder the NLR liberty pieces have purple looking ribbons, i barely noticed that after posting the photo.

Thats odd. Hardly ever see any type of purple shade on peltiers. This photograph had me curious though, because of a certain purple based type i've had in my rainbo pile.

Cool photo. I see a CAC rubix cube......

Even better, i'm coming for sure now. Bring pelts!
