Hello,

Found this in a tool box and could not find information on it through normal channels. The pliers? measure 9" long and the 3 step adjustable jaws open to 4 1/4". It seems like it would be used for gripping different size round objects. It is marked BOKER USA. Thanks for the help.

Oil filter wrench?

Some boker history, and my guess is Vacuum Grip Pliers .   I also have a pair of Boker  battery  pliers

Phillie: They look like Cannon Plug Pliers, usually found with rubber/plastic Jaw protectors on them. As I remember, Cannon is a brand name much like Crescent, and Phillips, and they are screw in captive electrical connectors, used in Military applications.

I don't have the info in front of me but if I remember right Boker was a German family of tool makers. One brother moved to the USA and manufactured there. There was also a Boker who was a tool distributer not a manufacturer. Some of the markings were Henry Boker, H. Boker and Boker

If your pliers should of had plastic jaw inserts the design patent (of June 19, 1956) for this type of pliers is here:

http://www.google.com/patents?id=PxdyAAAAEBAJ&printsec=abstract&source=gbs_overview_r&cad=0#v=onepage&q&f=false

At the bottom of the page there is this note: "References cited in the file of this patent. Plomb Tool Co. Catalog 4820, 1948, page 36, items 236 and 240."

If anybody has access to this catalog it might have the answer as to what purpose these pliers were mad for.

There was a thread on this tool on the old list, but I still had questions about this style of plier.  I bought two pairs of these about 15 years ago, sold one, kept one.  The one I kept was made by Utica, and it's the handiest tool for unscrewing difficult lids I've ever found -- especially those dratted safety lids!
Neither had ever  been fitted with plastic inserts.

Boker has been around for a long time, like the article pointed out.  The first Boker tool I bought was a Lancaster pattern hacksaw, which I used at Sutter's Fort.   It looks like the attached photo.

Non-marring pliers for brass/chrome plumbing fittings, probably...:

I saw a pair at the flea market and the old guy told me it was a fuse puller.  That didn't make sense to me being metal.  I just sold my pair a couple weeks ago for $1.

Thanks for all the info!!!

The Boker name goes back to at least the 1600's in tool/cutlery making.

So, you can be pissed at them for WW11 (and probably should), WW1, the hundred years war, and the fact that they aren't USA made,
     And still have a couple three hundred years of clear toolmaking to admire.

Boker is one of those firms that survive.

I came across these today. They were on my Phtobucket Message Board Page so I must of posted them here before the crash.

I have a 1966 Boker catalog.  It reads "A-N Electrical Connector Nut Pliers, USAF DWG. No. 4904591, Adjustable to properly grip Electrical Connector Nuts, sizes 16 to 32.  Forged of special analysis alloy steel."

They came with and without the nylon inserts like the Utica ones.

Cannon plug pliers. Some had hard rubber inserts, some didn't.
