Can anyone recognise this object ? You can judge its size by the Tesco carrier bag, I have not got the object just the photo at present.

I sent the picture to Leeds Armouries and received this reply

//Thank you for your photo query. We have collectively looked at it, puzzled and ruminated. Our collective feeling is that it is nothing to do with arms and armour. None of us have seen anything like this before. I fear it is something altogether different, possibly agricultural//
That seems to have narrowed the search a bit.

Melv, Thanks for the information, I was pursuing other lines as well as militaria and am open to all thoughts. I wish I could have the object in my hands as I think it would help to see what one can make it do.
Judging by screws its pre 1930s (as per Rick on Pawnshop). Am told it might be part of a lathe or industrial sewing machine.
With it being mounted on a wooden board, my guess it's a bench tool. I think it's an implement for extracting or inserting bushes or bearings into a larger machine part.
Question Author
Tambo, I would agree with an age of at least the 1930's but I have used machine tools for a lot of my working life and can't think of anything similar. Industrial sewing machine could be a possibility.

Melv, If used for inserting bearings etc. then what use would be the curly rod ?

Thanks to both of you for the suggestions.
I wonder if the curly rod is to keep a cable out of the way.
If you look on the spring housing, they're some notches, which must locate on to something. I think the rod is release mechanism for the spring.
Question Author
Melv, interesting thought but sudden movements such as a spring release would in my opinion be incompatable with fitting bearings or bushes both of which require steady pressure and not a sudden blow.I do agree with you about it being a bench tool, it has always been common practice to use a board in order to grip something in a vice or on a bench.
Bhg, since nothing on this article seems powered I can't see in this case that it is a cable tidy but I have seen a curled rod used for that purpose in the past.
OK, I tried to identify this in so far as I can.

I’ve expanded the image, cleaned up the background and marked up some of the key points. It's quite a big image now, so I've used a different upload site:

https://easyzoom.com/imageaccess/beef21a9632e4834ba13306c696e026c

After doing all that, I tried to identify this in so far as I can.

I’ve expanded the image, cleaned up the background and marked up some of the key points.

First of all, it looks like there should be a semi-cylindrical cover that protects stray fingers from the powerful mechanism.

It’s also worth noticing that the spigot at A is first fixed to the main body and second, appears the spigot to be hexagonal. The hex shape suggests that someone should adjust it with a spanner, or that it fits snugly into a recess on another object. Not sure about that.

Second, the two mechanisms at B and C look like they are canted over to push the bolt (?) forward. It looks as though these hinges can move the plate toward the spigot (A), against the spring. That would prime the mechanisms, allowing some kind of trigger to push the bolt forward.

I suspect that the means for doing that is on the reverse side. The shape at E appears to be a kind of access point with protective plate.

Then there are the adjustment screws (D) – one is missing. Can’t really see the purpose of those.

Finally, there is the tall, out-of-focus thing.

This is a red herring, but the transition between the straight, vertical bit and the curly bit looks like an old soldering iron. I think that is probably a bad guess. However, it could be some kind of heating element.

Windings like this are sometimes used to carry threads or fibres, so that the thread is easy to load, but moves easily. However, I cannot see any polishing that you would expect from such a thread.

My initial thought was that it is a mechanism from a gin trap, or equivalent. The animal triggers the spring mechanism, and the thing then snaps sut. The top piece would be a guide to support the traps. It’s bent like that to adapt to different situations.

However, looking at the area around mark E makes me think that there is a handle under there that controls the mechanism. It’s possible I edited the image badly, and the shape is just shadow on the Tesco bag. Even so, there is a big lug under there that appears to be some kind of actuator.

Can’t help much beyond that. Date-wise it could be anywhere from late 1800s (machine-made spring; fine machined threads on the adjustment screws) up to 1930s when cross-head screws came in. These single-slot screws are difficult to tighten effectively.

You can’t see the screw heads at D, but if they are also slotted heads, then I’d say it is for domestic use. If they are Allen screws, then maybe more industrial. However, the Allen head was only invented in around 1910, so not much of a clue there, either.
Great work IJKLM. The handle A looks as if it is cast to the whole frame and not to turn a thread to tension the spring. It must then have been used to rotate the whole thing, perhaps to release quickly, any stored energy in the mechanism.
Question Author
IJKLM, Thank you for the time that you have obviously spent on this and for your well thought out deductions if I get my hands on the object I will be able to test your theories.As for it's use I think that it will probably prove to be impossible without someone with first hand knowledge, I have got the photograph circulating various museums etc. but in the meantime any theories are welcome.

The righthand end has a scooped out shape reminiscent of a wad punch but the end view shows it to be to blunt.
I've also got the photo circulating several museums, including the mining one in Wakefield. As a long shot I've also sent it to a tool/jig making company.
I've been following this thread, would love to find out it's original use!
donny, do you know if there is a manufactures name or any serial numbers on it?
I've been studying it and wondering too Eleena! I think it may be part of some machinery. Love to know!
I've looked at it several times Patsy, googled the image ( too easy, no leads, doh!)
Sent the image to my ex engineering brother .. nothing.
I've even sent the pic to an American metalworking site..they're as perplexed as we are.
