I have a 1980's mechanical sewing machine that has a two step buttonhole and this year purchased another machine [ late 1960's I believe ] that has a two step buttonhole. The 1980's machine was made by Janome and I have not been able to determine a Japanese manufacturer of the 1960's machine but it was not Janome. 

I believe machines with two step buttonholes are quite rare. The four step buttonhole started to become normal in the late 1960's and early 1970's and has continued to this day as normal on all mechanical machines except upper end mechanical machines with one step buttonholes. The two step buttonhole went away in the 1980's ??

Anyone have a mechanical machine with a two step buttonhole ?

Adding a photo of the two step buttonhole control of the late 1960's Japanese machine.

How does a two step button hole work? For all I know I might have one. I'm thinking there is possibly a no name, very heavy, woodie/bla looking machine with an odd button hole maker built in - it's over in my shop... somewhere..... My parents are a very high priority so I rarely go home.

I'm thinking it has no manual either.

On the picture above, the button is raised which starts the machine sewing a bar tack [ when the foot control is pressed ] then it automatically switches to sewing one side of the button hole. When the desired length is reached, the button is released and drops to it's original position at which time the second bar tack is stitched and then automatically the second side of the button hole is stitched. The machine operator must stop the machine when the second side reaches the first bar tack. The button hole is completed.

My White 690 (1976) has a 2 step buttonhole - by extension the White 510 would too.

Thank you Zorba. When I did a search to find how the two-step buttonhole worked and what they looked like, I came up with a couple of patents. One was 4084524 from 1978 and was assigned to "White" I looked through a few of the White manuals I had and couldn't find it. The other was 3754521 from 1973 which was assigned to Singer. I did find that the Singer 636, 758 and 770 had the two-step AND the four-step buttonholes. There might be others, but those are the ones I found.
