The Latexometer

We conclude our series of rubber-related blog posts with this picture (see below).

(No, it’s not part of a weapon 🙂 ) Ever seen one of these before? This is, of course, a Latexometer. This instrument (shown above) is made to measure the specific gravity of raw latex; this one in our collection is calibrated in gallons of latex. The calibration is 0.5/2.5 lbs/gallons at 28.9°C.

Today Latexometers are calibrated in grams of dry rubber per litre of latex and adjusted at 28.9°C (84°F).

What’s this?

For those of you who don’t know what this is, it’s a carbuoy. Carbuoys are rigid containers, with a capacity ranging from 20 to 60 litres, used to transport liquid. This one in the picture was used to contain formic acid.

A Unique Letterhead

Letterheads usually have the company name and address; maybe even the logo / slogan. This letterhead (picture below) is rather unique, don’t you think? We were told it dates back to the 1920s.

Just curious: are those former Cycle & Carriage buildings still around? I know the Ipoh building is still there (but it’s not Cycle & Carriage anymore).

Alien Technology?

Nope! This is actually a carbide lamp 🙂

How does it work? Well…pellets or chunks of calcium carbide are placed in the lower chamber. The upper chamber is then filled with water. A screw valve or other mechanism is used to control the rate at which the water is allowed to drip into the chamber containing the calcium carbide. By controlling the rate of water flow, the production of acetylene gas is controlled. This, in turn, controls the size of the flame which has a reflector behind it to redirect light to the front.

When was the last time you saw a lamp like this?
