What is it? #131

The complex shape is because these low melting point alloys are soft and prone to creep, if used as a simple tension or shear link. The shape used here puts the alloy in simple compression over most of it, but there's still enough space to let it separate cleanly when melted.

From rec.woodworking:

#762: Dunno #763: Dunno #764: Baseball bat #765: Looks like a carburetor adjusting tool. #766: Dunno #767: I'd say there is a recess or hole over the top of the tee.

Golf tees taper quite alot. The hole may be a tight fit where the wood meets the tee but really loose at the tip. They also flex. So you could bend it a little or soak the block in water to soften it.

The wood was soaked in water for awhile then compressed in a vise. After the wood dried the tee was inserted. The wood was then placed in water again and expanded back to it's original size.

A leveling jack of some sort - 2 x quick release / set levers, cross bar through bolt head to fine adjust.

Fire alarm or door closer from an old warehouse. (dingbat)

I was hoping someone else knew. I still have one (KD) along with a ton of other special tools! Dave

I'll guess that there is a space that has been drilled out in the hole in which the tee sits - as though the hole was first drilled at a 45 degree angle, and rotated until it was verticle (in-line with the original hole). The space is hidden by the tee when the tee is in position.

My guesses:

It's intriguing, isn't it? It's clearly designed to clamp two round, or roundish, things. If it held them at an angle I'd say it was some sort of picture frame maker or something. But it holds these things parallel

- and fairly precisely.

KD tools.. the expensive ones that GM sends you every year. ;~) Points dwell adjustment tool for the GM caps with the window. The 4 and 6 bangers had to have the cap off with a screwdriver in the a notch in the distributor base for points adjustments. The pictured tool also worked with different attachments to adjust the carbs also.

#766 will disassemble itself when subjected to excessive heat. Similar items are used in Theatre proscenium fire curtains.

Assuming that's a wooden golf tee there....

It wood not be impossible to create the object from one piece of would by removing all the material which "isn't there" in the finished assembly, right?

I seriously doubt that was how it was done.

Most people that I've shown this piece of hardware think it might be some type of connector that was meant to give way under a certain amount of weight or stress, but I like your fire door closer idea. I haven't had any luck searching the web for similar devices, I'm wondering where you've seen one before and if you know any other terms for it.

Thanks, Rob

It's called a fusible link. see, z.b.

Leon, I should send pictures to this guy of some of the (GM/VW/HONDA and others) special tools I have been forced to buy over the last 30 years ;-0

It does appear to be a jack, and you're correct about the quick release levers and the fine adjust on the top. Also, on the top part, that's an arrow pointing to the right but you can't see the lower part of the arrow head. If you turn it around to look at the other side, it also has an arrow head in the same spot pointing right.

"MORGANS WICOX PATENT"

and

"M & W PAT 4 HICH LOCK", not sure about the HICH.
