Re: brass acorn

Hot Water Heater pressure relief valves are usually rated to release at 150lbs pressure at 210 degrees and the stem can easily be moved with two fingers. Try it. You have a HWH in your house right?
A Coleman gas lantern operates on much less pressure. I may not be right, but not because of those reasons.
Stuck in the open position you say, that would make it more likely a gas orifice or orifices, the pins keeping the holes open. But yes it would need a small opening on the bottom, I suppose.
Look, I am not jumping up and down telling others to eat crow. It is just a different view, maybe will lead to the answer.

The pressure relief valve you're talking about has leverage involved, you have a mechanical advantage with a screw thread and I don't think we are really talking about anything similar.
The Coleman Lantern on the other hand is a needle valve and the object we are investigating is not have anything like a needle valeve, i.e. threaded screw pin, extremely fine orifice etc etc etc.
Interesting to think about, believe that I would like to know as well and we'll just keep searching, won't we?

Hey Doc,

Couldn't be a "pressure relief valve" because if the pressure was from an orifice on the bottom, and pressure was being forced "up", the needles would be pushed up out of the holes, thereby slowing the flow and increasing the backpressure, thus, causing acorn shrapnel to be blown all over when this thing explodes.

Re: brass acorn

We may not have to look any further.. I like the acorn infuser idea.

I think it is dangerous to assume what is inside this unknown object.. I have changed and dissassembled enough valves to know there are many variations, different springs pushing in different directions. So lighten up!

Re: brass acorn

Actually the pulling of the pin pulls the pricks up and out of the acorn.There is no other logic that applies.

Re: brass acorn

Here's how it works. As the plunger is pulled out the spikes are brought out and tension is applied by a spring. The spikes being affixed to the bottom plate closer to the center line of the device than where the exit holes are located causes the spikes to splay outward when the plunger is pulled. When the plunger is released, the spring caused the spikes to return to the closed position.

Re: brass acorn

About the only other one hundred percent safe assumption is that the acorn is joined by whatever means at the junction of the body and the cap.  The maker had to get the guts into it some way and this is the only logical place.



Gollum and I seem to be on the same page here.

Re: brass acorn

Agreed! You beat me to the punch by two minutes. I was just posting the same diagram (yours looks better though).

Re: brass acorn

That's exactly how I envisioned it.

You took a step further.

Thank you for your effort and work! Perhaps, someone wil nail it. Now that there is a detailed explanation.

Re: brass acorn

Any one here know what a cuckle burr is?

Back to my original idea... a cheap, made in Pakistan, ninja bolas, or ninja casting net.

Why could this not be from a set of ninja bolas?  Bolas aren't a weapon to inflict an injury!  They are used to entrap the other person by being thrown (which would produce the centrifugal force to open the bolas) when the cord or chain connecting the bolas makes contact with the ankles, it wraps around them and with the spikes out, it would have a cuckle burr effect and latch on to the other person instead of just falling off and setting the guy free.

When not being thrown, it would allow the spikes to retract keeping them tangle free and a lot less painful to carry in your underwear.... ninjas didn't have pockets.

Same principle with a casting net.  Throw the net over the opponent and the spikes would reach around and grab on to the other side of the net making it impossible to set yourself free.

Are you thinking along the line of a GAUCHO BOLA?

Perhaps, just a different country.

Why did you choose Pakistan?

bola's are alot more stout...this one doesnt have the punch...weight looks to be light....UNLESS IT'S A TOY LIKE DIGEMALL SAYS...

.....or maybe a squirrel bola?

The more I think about it, my acorn tea infuser wouldn't work, because if you pack the base with acorn meal, it would force the pricks through the holes when you screw the cap on. WOW, shooting down my own ideas! NICE! Back to the drawing board.

Re: brass acorn

You know Michelle, I thought about that but why make a toy the child could get hurt on

Doc

Come on Doc! I had the Creepy Crawly Factory when I was a kid! Remember those from the late 60's? An aluminum block with molds cut in it of spiders, worms, centipedes, etc. You mixed up some toxic rubber solution (different colors), squirted it into the molds, plugged the aluminum block into a wall outlet, so the thing heated up to about the temperature where nuclear fission occurs, and it cooks the rubber. The instructions said to wait until cool before plucking out the bugs, but all my friends and I had blistered fingertips for the next few weeks after that Christmas (until we figured out how to use somethng besides our fingers to get the still hot bugs from the almost molten aluminum block)!

AND DON'T FORGET LAWN DARTS!!!!

I choose Pakistan because that is where all those cheap knives and all that other made from brass cheap stuff comes from.

The bolas don't really have to be heavy.  The originals were knots of leather.  I can assure you that that little acorn of brass would be plenty heavy for a bola.

Back in the seventies and eighties there was a plethora of cheaply made "ninja" weapons.  Things that a Ninja wouldn't ever think of using, that were invented late seventies to early eighties during the Ninja craze.  All these cheap weapons DIDN'T HAVE TO WORK!  They just had to look cool.

Good Logic!

I'll search that avenue.

Re: brass acorn

also called Bolas (Spanish: “balls”; from boleadoras), South American Indian weapon, primarily used for hunting, consisting of stone balls, usually in a group of three, attached to long, slender ropes. In hunting rhea, guanaco, and other animals in open country, the bola is whirled like a sling, then thrown parallel to the ground to entwine the quarry's legs. Bolas were also used by the gauchos of Argentina and Uruguay to catch cattle. We use them on the plantation to catch alligators also.

Dig,

I think the Pakistan thing is a possibility. The only thing that weight counts for with a bolo is the distance you expect to throw it (heavier travels further).

Now, I'm not attacking you, but your history of the "Nunchaku" is WAY off! It was invented in the late 1600's, probably in Okinawa, and they are very effective at close range (5-6 feet). Most every weapon in martial arts was originally used as a farm implement. As whatever country was the occupier wouldn't allow the native people to have weapons, so they learned how to use normal everday tools as weapons. The nunchaku were grain threshers. The "Bo" (fighting stick) was a walking stick. Kama were scythes for cutting sugar cane and rice. That's why if you look at all the old forms of martial arts, they have some really funky looking weapons. Swords and knives came along much later.

Re: brass acorn

Just think of the size of a rock that you would want to throw.  About the size of a golf ball up to maybe a tennis ball?  How heavy of a rock would you like to throw?  Maybe the weight of a lemon?  Take the weight of a lemon and divide that by three.  What you get is the weight of one bola, and there are three balls on a set of bolas... at least two, and sometimes up to seven or eight.  If a lemon weighs six ounces, each "acorn" would need to weigh two ounces.  For this acorn to weight two ounces, I would guestimate that it would have to be just ever so slightly bigger than an acorn, maybe about 1 and 1/4 inches long and an inch across with a hull thickness of about 1/8 inch.  The acorn could be much smaller if the walls are thicker.

Mike, I'm no expert on ancient ninja weapons by any means.  Glad you cleared that up.  I was under the impression that these came along in the late sixties, early seventies. I edited my post to make corrections and clear the misinformation. My apologies guys.

Re: brass acorn

I did a very little bit of research... it really didn't take long... and came up with this history.

Although the certain origin of nunchaku is not known (as are most weapons in the history), it was possibly invented in Okinawa. The popular belief is that the nunchaku was originally a short flail used to thresh rice (separate the grain from the husk). However some say that this weapon was not developed from a grain flail, and was created by a martial artist looking for a way to conceal his staff from the current oppresive government so he decided to cut it into three sections. The three sectioned staff is commonly known today as the sansetsukon. The nunchaku was derived from this, over time becoming what it is today.

Its development as a weapon supposedly grew out of the moratorium on edged weaponry under the Satsuma daimyo due to their restrictive policy of weapons control after invading Okinawa in the 17th century. (Some maintain that the weapon was most likely conceived and used exclusively for that end, as the configuration of actual flails and bits are unwieldy for weapons use, not to mention the fact that peasant farmers were unlikely to train for 'improvised' combat against professional warriors.)The modern nunchaku has been modified for its use as a weapon and would make a relatively ineffective rice flail.

The nunchaku as a weapon has surged in popularity since martial artist Bruce Lee used it in his movies in the 1970s. It is generally considered by martial artists to be a limited weapon. Complex and difficult to wield, the nunchaku lacks the range of the bo (quarterstaff) and the edged advantage of a sword or sai. It is also prone to inflicting injury on its user. Nevertheless, the nunchaku's impressive motion in use and perceived lethality contributed to its increasing popularity, peaking in the 1980s, perhaps due to its (unfounded) association with ninjas during the 1980s ninja craze.
