Anyone got ant idea what these are for ?
Found them in the back of the drawer with Tapers and candles etc . Oh yeah , they are 4 1/4" long and the square end is exactly 1/2" which would suggest they are pre 1975 ish

I think they are borers for cork or rubber stoppers.

Nah ... sorry Labby ... I did ‘t take a clear photo of the round bit . The round shaft is solid . The hole in the square end only goes down as far as the length of the square section .

Its possible they were a fancy taper holder or something but the holes are not full of wax although there are traces of wax all over them . Maybe them being in the drawer with the tapers is a ferfy or maybe its related

Oh thats strange, hope someone will know want they are for you

Well here's another .
Found a few of these burners under the prep room and in with them was a long copper tube slightly flared at one end and with a bulbous bottom.
There is a small spigot brazed to it . It is sealed .....IE there is not a hole through it into the copper pipe. Perhaps its a place to pick it up with tongs/pliers when its hot

The burner has an adjustable holder at each end .
Anyway , got it burning . Quite a good flame actually
So any Ideas on this one .
It does make a nice green flame when the copper oxides start burning off but its a bit elaborate just for that .I'm thinking maybe its heated up and then picked up by the spigot and something is poured into it ....but can't think what or why .

EDIT: OK scrap that . I just found another copper thing in the storeroom and it is obvious that it has not been used on a flame . Also on this one , the spigot Does go right through to the copper tube . Dooh , I think the one I found under the Prep room was just fully corroded

So I think I have two completely different apparatus , A long burner and a copper tube like a tall skinny version of a Pneumatic trough

wow found any money ha ha

It's all Priceless Labbie
I love finding all these old relics and trying to figure out what they were used for . Always hoping that someone might be looking and remember .

sorry can't help but a good bit of copper there.

It might be a Ruben's tube.
Gas goes in one end, you cover the open end with a balloon membrane and play music (as in a radio or mobile phone) against the membrane. When you light it the flames jump to the beat of the bass notes.

Physics teacher was hoping it was Ann but we decided it wasn't for that purpose
But gee those things a pretty cool .
