What is it? Set 431

2499: Some kind of net needle?

2502: Course plotter with sight.

2502. Antique surveyor's alidade. For use on a plane table. A more modern one.

2501 is for opening Bottles and Cans. The old style Bottle opener is just before the Tail. Twist tops are handled by the "inner circle" by the bumps and Pop tops are started by the first fin behind the Head.

2499: Harpoon. Dave

Fishing spear. Lloyd

Not sure the 1st one is anything in particular other than a handle that clamps to a square shaft.

Dave

I'll admit, I have totally no ideas, for any of them.

You did it -- totally stumped me.

#2498 Pressure cooker?

Bill

Looks like I might get one this week!

#2500 A clamp for holding the leather tip of a pool cue in place while glueing it on!

Bill

Looks like a spring loaded cutter head on it. Maybe to square off the end of a pool stick or something similar.

Karl

Alidade is correct.

Yes, it's made by the people that make Yeti coolers.

It's not a cooker, it's something a little more sinister than that.

2499 looks like it could be old Ice Fishing Ploes.

Crazy Ed

That's it! If you look really close you can see some line that is wrapped around the middle part of the upper one.

They were marked as ice fishing poles, I was thinking that the spikes were for chipping a hole in the ice, maybe they were used as both a spear and a chipper, hopefully someone will let us know for sure.

I'd guess any Ice the points would be useful getting through would be way too thin to walk on. Rather I think the points are for standing the pole up on the ice. Once a fish bites the pole would fall over across the hole indicating a strike like the flags do these days.

Crazy Ed

I suspect they are rescue spikes. All kinds of things have been used for ice-rescue spikes, including dowels with nails driven into their ends.

Posting from Rec.crafts.metalworking as always.

2497) I first have to ask a question: Does the metal part pivot around the pin near the large end, and stick out the small end? If so, I would need to see what that small end looks like extended.

However, if it does not (I think that there is a smaller pin to prevent that), I could see this being used as a wrench for square-headed screws such as are common on lathes. The metal can take the wear, the large rivet gives it strength to avoid spreading, and the wood makes a more comfortable handle than the forged metal wrenches for the purpose would have.

2498) It looks like the top piece is a Fresnel lens, so it could be used to focus sunlight onto something held in the center of the bowl. Perhaps to light a cigarette or a tobacco pipe's contents? But the green glass would absorb a lot of the heat out of the sunlight.

So a second option might be a disassembled high voltage insulator?

Is that some form of tape on the elbow in the third photo? And is that a loop of wire sticking through it, or a marking on the tape?

2499) If the points were not so sharp and long, I might consider this to be some form of shuttle for weaving. The yarn could be wound around between the projecting horns on the first one, and perhaps the second one had similar horns which were somewhat broken off.

As it is -- perhaps for gigging fish? (But there should be a barb on the pints for that.)

2500) This looks like a tool for forcing a cork into (or back into) a wine bottle.

2501) Hmm ... the ridges in the center hole look as though they would be good to grip a ribbed bottle cap of a certain size, and some of the lips appear to be reasonable for lifting press-on caps for something like a jam jar. Not too sure about anything else.

2502) A rule for use on a chart table -- to sight though it to a landmark, and the upper edge of the rule (if unlocked in the center) would turn it into a parallel rule, for drawing a line parallel to another or to the sighting.

Anyway, for navigating or surveying.

Now to post and then see what others have suggested.

Enjoy, DoN.
