What is the name of this lock?

[CompFX]

It has "HUNTFILED MFG. CO." Stamped into it, and then a number 4 stamped on the top of the lock where the key hole is.

I pulled the patent number off the above image and searched it. but there is nothing worth the 20 minutes of reading. The picture of the original patent is pretty self explanatory.

Its just a unique lock, and I still cannot find a use for it other than in my shadow box.

It looks very much like tractor trailer security seals while moving cargo from warehouse to warehouse. Unlike your lock which can be removed using a special tool, today's seals snap shut and must be removed with bolt cutters.



I wonder if your lock has a similar purpose.

thanks for sharing it.

It is always good to see interesting locks. Just one question: Were you spinning in circles while taking the pictures?

[Jaakko]

Were you spinning in circles while taking the pictures?

As you can see from the filenames, the pictures are actually scanned. Hope the OP didn't scratch his/her scanners glass..

[CompFX]

Yes, they are scans as my camera has gone on strike by blowing the flash bulb.

I didn't feel this lock was that special, so i put the res at 200 dpi to keep the file size small. Faster upload and faster page load.

Barrel locks are typically used to inhibit tampering with public utility devices such as valves and meters for gas, water and electricity. A common barrel lock is the plunger style. It incorporates two balls which are held in the extended, locked position by a spring loaded tapered mandrel. The number of different key shapes is very limited, the keys are easily duplicated, and common objects can be used to open the lock. The design of the plunger style barrel lock is such that it holds water, suffers from corrosion and becomes inoperable in freezing temperatures. It is also easily disabled by simply inserting a foreign object into the key hole. The head is generally swaged onto the barrel and is easily broken off.

As a side note that schematic of the lock reminds me of the triggering device in "Bouncing Betty" mine

My father-in-law is into that sort of stuff also.

It's a tamper seal lock. Often used on power/water meters. No real security in them, they just make sure no one has been playing around with whatever they're on.
