Help Identifying This Brown & Sharpe Tool/fixture, Please.

[TORQUIN]

I picked this up the other day, as a possibility of using as an angle plate, but would like to know what it is and what it's used for before I do anything with it. Searching Google for the numbers has yielded nothing.











Thanks,
Chris

3366 looks to be a tilting vice.
920 could be a precision straight edge used to help set the vice angle.
Very Very Nice Score.

B&S calls that a #2 adjustable swivel vise. I just picked up a B& S model 2L surface grinder and it is shown in the 1946 operation and maintenance manual. Yours may be a different size, but it looks the same. The "No, 3367" is almost certainly a serial number, the s/n on my grinder in two places is in the same font and style and the main s/n is raised on a boss just like yours. 920 is likely the part number of the straightedge, like tertiaryjim said.

So do you think this is specifically for grinding, or grinding and milling? I am trying to hunt more info on it, including examples of setup, on Google now.

Thanks,
Chris

Yep, these smart folks here figured it out already. The very fine adjustable swivelling machine vise able to be tilted 45° each side of horizontal and fitted with 5-inch wide, 1-inch deep jaws in a hardened tool steel that could be opened to a maximum width of 2.75". Used on a surface grinder. The 920 is a b&s parallel.

The 920 is a b&s parallel.

That's what we called them, straight edges don't have the bulk of parallels.

I don't have enough knowledge to know what B & S had in mind for it, but in my playbook, wherever it can handle a job, it is welcome...

Hi Torquin,

I found another picture in a an old Brown and Sharpe manual:



It's in the Machinery and Tools Catalog No 136 from 1916.
That manual is broken into three parts over at Vintage Machinery, here's the direct link to that section:
http://vintagemachinery.org/pubs/detail.aspx?id=5342
see page 122.

This page lists all the manual parts:

I'll bet you will. I got it for 40.00.

Thanks to all for the information. I hope this will be handy on the grinder or mill.
