Dating vintage Starrett tools

here are two more items in my starrett stable. One is a combination set that has a repair near the 60-120 degree place, it is a number 7. then a 2"-3" micrometer that is missing its thimble ! 100 years has been rather traumatic for tools over here in blighty......2 world wars etc etc etc. also a picture of the 1"-2" mike that we have already talked about....The photos have not come out very sharp.. The mike is a No226 and the reverse says Pat 10 march 1891 and May 4 1897.View attachment 76281View attachment 76280View attachment 76282View attachment 76283View attachment 76284and May 4 1897.

Nice picts. steamguywilly. At least you didn't over clean them, and ruin their patina, like many I've seen. Too many vintage antique tools are wire brushed and shined to ruination, damaging the markings and removing the original edges.
 
I found this tool today at the car boot sale and i could not find it in my brown and sharpe ,or buck and hickman cats. Iknow it is not L.S.S. make but it is american !! Is it something to do with the drill angle?? If anybody knows it would be interesting to find outgoodall 1.jpggoodall.jpg

That's a Whitworth-Standard Adjustable-Notch Center Gauge. Looks like it is missing the locking thumbscrew.

Thanks for that information, i thought it might have been something to do with the Whitworth thread system. the mark that said 550 had a small zero with a line under it. I thought that might been the catalogue number. Yes there is a small tapped hole for the thumbscrew and it is threaded 8BA, Do you have a date for your illustration? Did L.L.S make a similar item or was it patented.

Sorry, I should have mentioned, that was from a 1926 Goodell-Pratt Catalog.

L.L.S? Do you mean L.S.S. or L. S. Starrett?

I haven't seen a Gauge like this in any of the other toolmakers' catalogs.

Thanks for the info, Yes i did mean Starrett. Thinking about TPI's were there any rulers made with 14 and other divisions produced. I have never seen any, but if you wanted to draw whit worth threads accurately with paper and pen how would one go about it ? Just wondering

The table below is from my 1938 Starrett catalog. As you can see, 14 divisions was available in the No. 1 graduation option, but I have never seen one of those.

Just curious-why would you need to draw a 14TPI thread?

I have never drawn a thread, I always write what the thread is after drawing the symbol for it. I suppose if you were designing some piece of machinery and you wanted to show the actuall thread relationships with other dimensions on the componant, you may wish to draw the thread to see if there was enough space ,room,strength and so on for the item to work satisfactorily. It is interesting to see that these rulers do exist though. Thanks for all this info, and sharing it with everybody.
