Back in 1900 or so, most of the Chinese population could neither read nor write, the ideographic alphabet , containing thousands of characters was learned by only a select few....

This posed a problem for the fellow running the tool room in a Chinese machinist shop, who rather wanted the workers to return all the tools at the end of the day, but had no way of making a list of tools that anyone could read.

His solution was this pictographic tool chart, written with a paint brush in the traditional method of writing chinese characters, but with simplified symbols for each tool.

For example, No. 1 represents an ordinary open end wrench, No. 2 is a monkey wrench...

How many of the rest can you guess?

What are machinists who can't read or write going to do with letter and number stamps?

I needed that when my boys were young!

Even now they sorta need the tool outline on the pegboard to put the tools back in the right places.

Probably they didn't use them.  I'm not being glib here.  But then, there really aren't Chinese letter stamps, and the Chinese number system is pretty direct and easy to know. 

I've watched and worked with Chinese and Viet-Namese tradesmen, especially carpenters and shipwrights.  I found them a highly skilled and inventive lot.  Amazing, really.

Oh.  I see the problem -- the stamp set.  Still not so hard.  Thinking about the way a shop would run, not everybody needs to know letters and numbers, and younger workers often get clean up duty at the end of the day.  They wouldn't have to know the letters or numbers, only that there was a set for them to return.

This is fascinating!  Where did you run across this?  Provenance?

There was a related article somewhere that I can't find about the railroad telegraph system, and how dispatching train orders was a problem because the dispatchers couldn't read the telegraphed orders. Apparently, to send a telegram, the operator looked up each glyph in a book, and telegraphed the number of that symbol. The fellow at the other end then looked up the number and drew the pictograph associated with it. Neither had any idea what the message sent actully contained....

Thanks for the link.  No wonder these looked kinda familiar.  The shop was in Hai Phong, Viet-Nam.  I worked with shipwrights
from Hai-Phong.  Symbols like these are commonly used by these guys for all sorts of things.  I've come to use some of theirs
myself.  Very cool!
