Old jack ID

Does anyone have any info on my old jack? I have seen similar ones online, but no matches. I am interested in its use, if it is complete, value if any, etc. TIA. john

it does indeed look incomplete ....

 

the web points to an old Duff Norton style industrial jack..

 

I know absolutely nothing about the topic which, as I'm sure you know, has never stopped me from offering an opinion.

Isn't it an older version of this?

I see an ARR stamping on it, maybe you could use that in your research?

 

I checked Ebay for "antique screw jack" and there were several sold items. The prices ranged from $20 to over $100, with and without the lever. The ones that worked sold for more money. You can check there for range of values. I don't think it's a throw away, although I don't know what people do with them if they don't work. Parts, maybe or industrial design objects? IDK.

 

Here too, I think. I've seen bottle jacks before, but unless you have all of the pieces it's just one heckuva door stop.

 

Yes, and a few other brands as well but no one I have contacted has any definitive info, or ANY info on old jacks. It's been a dead-end journey so far.

 

Yes, very likely Alaska Railroad as I bought it in Alaska.

Lever? Like a pry bar? I've used it with some kind of leverage and it lifts like hell. I would like to find out what this lever thing is; maybe I can find one. ?? Thanks. j

 

Yes, non-working jack is a boat anchor.

 

Debra: Holy Chitina! Where'd you find that? I've been Googling for days, all in vain, but that puppy looks like a younger sister. Thanks! Hottest lead yet! I will contact them. Cheers. j

 

Well, that is a very useful bit of information that you should have revealed in the beginning.

from an AI query -

"On your vintage heavy-duty mechanical journal jack (specifically a Duff-Norton or Simplex style heavy ratchet screw jack), the stamp "ARR" stands for the Alaska Railroad. [1, 2]
Why it's marked "ARR"

• Ownership Stamp: Major commercial railroads custom-ordered these massive mechanical jacks from manufacturers like Duff-Norton Mfg. Co. to use for heavy track maintenance, locomotive repairs, or stabilizing railcars. To prevent theft and keep inventory straight among different rail lines, the foundry cast or hot-stamped the railroad's reporting marks directly into the steel housing.
• The Reporting Mark: In the North American railroad system, ARR is the official assigned reporting mark unique to the Alaska Railroad.

Fyi, @jklingel, I found it via Google Images. Can be a very useful tool. And, as above, location is very important to us. We're an international forum so it can help narrow identification down greatly.

Yes, but this may appeal to Alaska Railroad enthusiasts.

 

Wow. Thanks. I did a lot of Googling, but maybe an AI search is different? ChatGTB (or whatever it is)? Google Images? Will have to learn about that. Thanks. j

 

Hopefully I can find a rich one that needs a jack! j

 

Go to Google and look for the camera icon in the search bar to the right of the microphone. Click there to upload a photograph and close images will come up. Sometimes they're even a match.
