Picked this up recently.
Seems to be some sort of lab scale. the ruler is a true inch rule.
The spindle? rests on a pair of blades. it is also hollow connected at the front to the pipe in the middle of the cup on the right. There area couple of heavy balance weights. Fitted with antistatic wires.
HG Brown and Associates Melbourne stamped on rule.
I contacted them and the manager had no idea??
Perhaps someone here may recognise it. looks like it is missing something, I am hoping to get a pic of the real thing.

Interesting, It is some sort of precision measuring device but what for ???? the pipe/spindle seems to have a coupling on the front that may imply a pressure connection.

Having calibrated balances in a past job, it looks like no balance I've seen before.
To be honest, it looks like an 'artist' has grabbed bits and pieces from Granddad's shed and bunged them together.
Several clues are:
• the high pressure fitting on the 'balancing' pivot point. (No logical reason for that fitting to be on a balance pivot as the connected hose would be friction preventing balance)
• the frame would introduce friction preventing movement to balance. (Balances use a knife edge and vee to minimise friction)
• the earth straps on the base look out of place as well.

My GUESS is that it is for measuring a flammable liquid. Earth straps to prevent static build up. Liquid comes in the front connection and flows into the round bowl on the right. Just don't know what happens then.
-
Flammable liquids are usually measured in flow meters. To keep the fumes contained.

Ta gentlmen. The plot thickens
I have 2 of these. Made by differnt firms both use Blade in v's supports .
There must be something missing from the left. Bits there all on the right.

Perhaps you could send a photo and a request to the SA Historic Tools Association who may be able to help identify what the item was used for. They have previously identified some wierd items that I had. See their web site at http://communitywebs.org/sahta/ (http://communitywebs.org/sahta/)

Yes but this is for very small quantities. I have forwarded it to an ex work colleague, an oil and gas instrument engineer, hopefully he may have an answer.

I'm happy to be wrong. Learn something everyday.

Maybe more photos from other angles might help.

It is just the earth straps that make me think flammable. The earth strapping on cable trays in the oil and gas was so over the top it was a joke.
-
Earth straps only on one. Otherwise both nearly same.
I could get more pics monday
Thanks for your interest gentlemen

I took another look at the picture and zoomed in and I recognised, "N.G. Brown" the HG had me confused.
N G Brown are still in business and make and sell masses for calibration. Anything from cast iron masses to stainless steel reference masses. From micro gram to 20 Kg.
They also sell scales.

Contacted brown first up. Manager had no idea.

It must be very old

Have you seen pault? :grin
Nah, it's just the beard!

I'm asking a friend who's been in the industry for decades. See if he or his boss know what it is.

"No idea Gary. Do you know where he got it from?"
Fred has been in the industry for at least 3 decades.

a reply from the manufacturer
This is a Bureau of Meteorology high altitude balloon filling apparatus stock number 5092.
They were manufactured by N.G. Brown in the late 1960’s through to the 1980’s or 1990’s for the BofM Melbourne.
The balloons were hydrogen filled and a range of sizes ranging from 20g to 100g and used for upper wind observations.
I have a second one made by P S Sharman & co of menbourne.
Never expected that. Thanks for your interest gentlemen.
-
That is very interesting.
I'll have to share the answer with Fred

Wow that was certainly left field. Very fascinating though. :clap

Interesting for you to have thrown that image on here just to see which way the wind blew ......
And then someone popped up with an answer.
I think your search for an answer got blown out of all proportion.
-
It certainly was an interesting conundrum. Just the sort I like.
And I'm happy to be proven wrong.
