First one looks like a plumb bob with internal string winder of some kind?
-
Second one is some kind of vise. Not sure what it might be used for?
-
Then there's this bird feeder looking thing. Any ideas?
-
Then there's this flat bar with someones name stamped in both sides. Bar is tapered at the end like a flat head screwdriver.

The first one does look like a plomb bob. We could have used that years ago when my good friend was trying to center the windmill over his well. He used a Pepsi bottle with pretty good results.

The "bird feeder" thing is an old clothes washer, the flat blade screwdriver is a screwdriver. Called a "turnscrew" by our overseas cousins. I would expect you will find a name on the plumb bob once you get it cleaned a bit.
Starrett made a bob of very similar form but they filled it with mercury to give it more weight. Maybe they made one without the mercury and used the space for the string reel?

+1 on the turnscrew and plumb bob.
I have seen the bird feeder/clothes washer before but did not know what it was. One for the memory banks.
The vise thing, no idea but most likely a clamp or adjuster of some sort.

The Starrett plumb bobs, style 87 series were mercury filled, older ones were round top, newer ones have a hex top so the don't roll away when laid down and a hardened steel point that is black instead of chrome plated like the rest of the body. The 177 series were similar looking to the 87's but were solid steel, these didn't weigh as much as the 87 series. I think there were 4 different sizes in each series.

The vise is a spring vise for a flintlock rifle.

I hope it was sealed in somehow :huh:
But then when I was a kid my dad taught me that if you poured some mercury into your hand and rubbed a penny in it hard enough for long enough, it would turn shiny silver. The reason for this was because "A dim-witted store clerk will take it as a dime every time"! I guess that's how they got by during the depression in dust Bowl, Oklahoma. And it probably explains a lot :grin:

The 87 series have a cavity machined in the body that is sealed with a screw that can be accessed by removing the top of the plumb bob.

Lads who did enough of that probably became dim-witted store clerks.

Hey, I never rubbed no merkery on me but stop talking 'bout me....

Good job, lazy!

What about this force pressure gauge? What's that used for? The attachment is all aluminum.

Hello, I have no idea, but a few more pictures from different angles will help. Regards, Lou

Applying pressure to the silver plate forces the gauge dial to go up, so it's some kind of pressure gauge. Just wondering what it might be for though.

Anything.
That guage is a pretty common item, used on everything from steam heating equipment, oil field equipment, or anywhere you need to measure less than 600 psi. We use lower pressures in fire protection. Most older ones were 300 psi, if I am remembering correctly.

I understand the function of the gauge component, what I was wondering about is what is the physical pressure or weight component that is screwed in to the gauge. Closest I've gotten is something that looks similar - a pressure conversion gauge - https://www.wolterpyrotools.com/?page=cc_catg&catn=750

Sorry, I hadn't noticed the 2nd sheet. :embarrassed:
It can be used for a lot of purposes for checking force or weight. Technically, you could use it as a torque wrench, but not very accurately with that guage.
If you know the area of the piston face, multiply that by the guage reading to get the force applied to the bottom side of the tool.
If the piston face us 1/2 sq, in. and the guage reads 100 psi you are applying 50 pounds per square inch of force.
I guess sonetines you may want to apply an exact force to a part. Maybe it can be used on a press between the ram and a part? Another use could be to make sure weight is distributed equally between various points.
Be careful though, a 1/2" piston face is close to 1/4 sq. in. I always think of it this way, in a 1" square there are four 1/2" squares. Circles are a little different - radius squared times pi.
I hope I'm accurate, my brains fried. Big tool day for me and it wore me out. It seems like a pretty specialized tool, but it also seems more accurate than a spring mechanism.
I wonder how it would perform compared to electronic force measuring tools.
