Shaw / Diatipt tools – what are they for?

[ManofkentParticipant @manofkent]

Hi

I bought a lovely ML10 lathe about 18 months ago, and have been hapily using it since.

It came with lots of extras – mostly Myford accessories. I am still working my way through the extras box!

Anyway – in that box were 5 tools like the picture shown.

The one shown is stamped DIAPIPT 57048.

The others are similar but most are stamped SHAW, or SHAW AUTOFLOW.

Perhaps on the large side for an ML10, the pictured tool shank is 5/8" square, and approx 7.1/2" long.

Does any of you clever people know what these are for?

Yes I have googled it but can't make head nor tail of the results!

Thanks in anticipation

John

A. Shaw & Son made glass cutters and diamond glaziers products.

From the 1951 Directory for the British Glass Industry:

SHAW (A.) & SON (DIAMONDS) LTD., WATERLOO WORKS, WATERLOO ROAD, NORTH CIRCULAR ROAD, LONDON, N.W.2. T.A., "Scindere, Norphone, London". T.N., GLAdstone 1171/3 (3 lines). Established 1815.

Steel wheel glass cutters and loose wheels; glaziers' diamonds.

Managing Director: A. H. R. Shaw.

Secretary: Miss R. Pizzala.

Autoflow Engineering made the 'Autocyl' toric smoothing and polishing machine, used in optometry.

So, I would hazard a guess that those tools were used in the making of glass optometry lenses.
