Nice set. Can't even guess at a couple, but that won't stop me from
trying.


1471: It seems that something can fit inside the grooved ends, with
the steel 'spring' locking it in place. At first, before I saw that it
was one-sided, I thought maybe it held a pool cue or something, but
now I think it might be made to be hung on the handle of a pail to
make it easier to carry. The two-sided grooves means it can be
attached by twisting it on, and the springs keeps the wooden piece
from slipping down the handle, or falling off.

1472: Drive motor for an electric garage door opener. The slots are so
that the slave gear can disconnect in case the door jams.

1473: Why do I instinctively think of a big bass drum in a marching
band...? Or, if this is an electrician's truck, the ring around a gas
station sign like this:
http://tinyurl.com/64u8lm


1474: A novelty boot jack: http://tinyurl.com/6m97fx


1475: A hay bale lifter like on the front of this tractor, but
midified to use in a barn:

1476: A diamond cutting machine.

Quite a tricky set this time, at least for me. Wild guesses follow.

1471 - Seems to be some manner of marker that clips onto a cable or
rope. Being made out of wood, it's unlikely to be used as a weight, and
it doesn't look too safe to use as an electrical insulator. Maybe it's
placed where two ropes cross to avoid chafing against each other?

(Maybe it's a demonstration model illustrating a form of the Chinese
finger trap?)

1472 - A smallish electric motor with a short doubly-keyed lead screw
attached. Possibly this formed a part of a benedix drive to engage the
load only when the motor was energized, as for a starter motor for an
engine.

1473 - My initial thought was that this was part of a spinning rack such
as is sometimes used to keep track of order slips in diners. That
doesn't seem to go with the other tools and materials in the truck,
though. Maybe it's a part of a light fixture or other item these
tradesmen happen to be working on? Maybe it's a collar to go around an
open manhole to hang stuff down and give some visual warning that
there's an open manhole?

1474 - Portable gun rest for target shooting?

1475 - The claws appear to clamp onto something to hold and move it,
engaged or released by the lever with the worn-off orange paint.
Probably, it's used to move bales of something; I'd suspect not hay, as
hay bales lack the structure to be grabbed this way, but perhaps
newspapers for recycling or something similar.

1476 - Possibly these turn (or, perhaps more correctly, spin) brass
finials?

Now to see what others have to say.

1471 I am going to guess that this is a grip extension of some kind. My
thoughts keep coming back to archery and that this would go on the bow but
I'm not too sure about that.
1472 My first thought was that its a worm from a worm reduction gear but not
sure now I have seen smaller versions of this setup that operate door locks.
So maybe this would be for a high security vault?
1473 no idea apart from a connector for two bits of ducting.
1474 Again no idea my only thoughts would be an ornament.
1475 Hay bale grabber?
1476 I am guessing that these are for making watch gears.

If I walk into a bank with #1474, I could get enough money to buy the
rest of these gadgets.

#1475 is what you'll get if you get caught trying this stunt.

I'd guess 1473 is an overhead rack for pots and pans, probably out of
a restaurant or commercial kitchen.

I'd guess that #1476 are all wheel cutting engines for watch and clock

I agree the distant picture makes one think of that, but looking at the
details more I decided not...it's got too many other attachment that
wouldn't work well for the purpose. I think it is a connecting piece
between other ducting or similar as another proposed earlier...

Posting from rec.crafts.metalworking as always.

1471) Hmm ... looks like a sliding clip to go on something
like clothesline. Looks like wood and spring steel.

1472) Well ... an ACME thread on the motor shaft, but too
close to the metal shield for normal use, so I think that it is
some form of feed device.

Looks as though the threads were turned as an afterthought, and
that it was originally to drive a pulley or something similar
with a double keyway.

1473) For winding the hoses shown on smaller reels to the left?
Those hoses look to be for oxygen and some fuel gas.

It looks way too flimsy to be caging the tire while seating the
bead to prevent explosions.

1474) A child's toy with a hidden compartment?

1475) A hay bale grapple?

1476) Decorative metal turning engines -- for engraving regular
decorative patterns into metal?

Holtzapfel (sp?) made the fanciest one that I have heard of, and
these are far below that.

Now to see what others have said.

Uh-h, I think I see the welding cables hanging behind the driver's
mirror. I'd say the owner isn't very concerned about wear and tear.

All those holes make me think the length can be adjusted.

Is the truck used to repair farm equipment in the field? How do you
seat the bead of a tubeless tire in the field? I've seated beads with a
limited air supply by tightening a rope around the tire to push the
beads out to slow the escape of air.

I think this band was a closed hoop only for traveling. To use it, you
would make it slightly shorter than the circumference of the tire. You
would put it in place with a gap between the ends, put one or more nylon
straps around it, and tighten them with ratchets. The hooks extending
from the band would keep the strap or straps from sliding off the tire.

When this squeezed the beads out against the rim, you would apply air
until the air held the beads out. While tire pressure was still low,
you would loosen and remove the straps.

Good point, I had meant that they were all used for making one particular
device.

According to the museum in which I found these, they were not used to make
clocks or watches. Although the craftsman who used them was also a
clockmaker, the devices on my site were described as being used in a
different trade. So perhaps these are clockmaker's tools that were used in
another trade, or maybe he modified some of his clockmaker's tools for
making other devices.

Patent 4997020 is for a device where a metal band of several sections
would be tightened around a truck tire to seat the bead. It says
putting a strap around the tire was an established method, but this
would result in asymmetrical pressure, due in part to friction between
the strap and the rubber.

1473 could reduce friction in tightening a strap. The hooks could also
be a means of compensating for asymmetrical pressure by exerting pull
between hooks across the circle.

Good point.

Looking at the stuff in the back of the truck, it looks like this is a
service vehicle for diesel tractor-trailers. Maybe this is some sort
of fan shroud for a big diesel engine? And the things that look like
handles are just framing to guide hoses, etc?

This is a tough one. Can anyone analyze all the other stuff in the
back of the service vehicle for clues?

I dunno...the patent device seems to be made of a series (at least 3)
sections that can overlap, so tighening the device reduces the
circumference. This thing seems pretty solid.

Some observations: the 'handles' are directly opposite that D-shaped
stain on the opposite side. It might be the bottom, with the two
handles on top at 10:00 and 2:00.

The truck seems to be a welder's truck....does this have anything to
do with welding? If not, could it be something he is taking back to be
repaired?

Around the rim of the ring are 7 'rods' that extend beyond the ring.
Are the ends of these rods bent outward, or are there little 'knobs'
at the top? And between each rod are 5 small angled things, that look
like they could be used to secure a flat plate on to the ring.

Hmm....I love a mystery, but less so when I know it might never be
answered.

It's not that patented device, but the patent describes the obstacles to
seating a bead by squeezing the circumference.

Some observations: the 'handles' are directly opposite that D-shaped
stain on the opposite side. It might be the bottom, with the two
handles on top at 10:00 and 2:00.

I wonder how many there are. I now think the handles and not the hooks
keep a strap from sliding off the tire. The strap would be threaded
under the handles. Using metal band between the strap and the tire
overcomes one of the obstacles mentioned in the patent: friction.

The truck seems to be a welder's truck....does this have anything to
do with welding? If not, could it be something he is taking back to be
repaired?

Would the tire be his spare? Isn't a spare normally carried somewhere
other than the middle of the cargo space?

Around the rim of the ring are 7 'rods' that extend beyond the ring.
Are the ends of these rods bent outward, or are there little 'knobs'
at the top? And between each rod are 5 small angled things, that look
like they could be used to secure a flat plate on to the ring.

The metal band would allow a strap to slide fairly freely as it squeezed
the circumference. According to the patent, there are other factors
that make a squeeze asymmetrical. Suppose you tighten the strap and see
that the bead is not sliding into place at some spots. What now?

Imagine you reach for a sort of load binder with a few links of chain on
each end. If you hook the chains to two of those hooked rods and pull
the lever, that should deform the circumference. I think that could be
used to manipulate the bead into place.

I think what look like "small angled things" are holes, allowing the
mechanic to mount as many hooked rods as he wants at the spacing he chooses.

Sounds like a good possibility, but I'm not yet ready to pronounce this one

recognize it and provide a definitive answer.

1471 is a leather working tool that is used to cut pieces off to shape

1474 is a boot jack. You place one toe of the handle and the heal of the

Hmm ... no click to make it bigger, but I saved it and cropped
in as much as I can given the jpeg artifacts. (Not sure how much better
the raw image from the camera would have been -- this one has been
processed by a Microsoft program based on the exif data.

anyway -- it looks to me as though at least some of the holes
around the ring have studs in them facing in towards the center, which
makes it's use as a tire bead setter less likely.

I see two oxygen tanks lying down, instead of locked upright as
they should be. A tank of some fuel gas (I don't think that it is
acetylene, so perhaps propane or natural gas) at the right front
corner. Acetylene would have to be strapped upright to make it usable
without a few hours of upright resting after being turned upright from
lying down.

The rods with the hooks on the ends lok as though they might be
used to hook the blow-molded plastic sign covers in place if it is truly
a ring for a sign.

Of course -- it could be totally unrelated to anything else in
the truck -- having simply been scavenged from somewhere as a source of
metal. :-)

This metal ring is a device used in pipeline welding. It is clamped to
one of the pipes being welded together, at a specified
distance from the weld location. In the case of automated welding, a
motor-driven apparatus with multiple welders is clamped
to the band, and then travels along it, and around the outside of the
pipe. This allows the initial "root" weld to be followed by
multiple "hot pass" welds, and then a final "cap" weld. Pipeline pipes
are so thick that multiple welds are required, and no human
can manage it. By varying the distance between welders, and the speed
of the motor, the previous weld will have attached, but will
still be hot enough that the following weld will bond, not only to the
pipe itself, but to the material from the previous weld.

After the weld is complete, and has cooled, an ultrasonic scanner is
clamped to the same band, and circles around the pipe in the
same manner. It fires ultrasonic pulses into the weld and looks for
places that the weld is faulty. In the case of a perfect weld, the
sound
travels unimpeded through the metal, but if there is a fault -- a
"bubble" -- the sound will reflect off its surface and will be
detected.

As you can imagine, pipelines are very expensive to build, and the
consequences of a rupture can be catastrophic, especially if you're
talking about a pipe on an ocean floor. If you're putting it down, it
better be good.

The author of this post worked for a couple of years building
ultrasonic scanners used for exactly this purpose.

talking about a pipe on an ocean floor. If you're putting it down, it
better be good.

The author of this post worked for a couple of years building
ultrasonic scanners used for exactly this purpose.


Thanks! Do you know if there is a particular name for the ring? I'd
like to find a link that shows one, to add to the answer page. I've
done some searching but so far I haven't had any luck.

Thanks for the links! Great job on finding that, I discovered a similar
video to the one you posted except with a larger pipe, here is the link I
put on my answer page:

In the American patents I found, the guide ring is called a ring gear.
A worm gear on the robot engages cogs on the ring. I don't know if the
Australian guide ring has cogs on the underside.

The Australian ring is about an inch from the pipe. This would allow
space for rollers by which the robot would grip the ring. On the
welding side, the robot has a skirt extending almost to the pipe.

The mystery ring has hooked rods. Wouldn't they preclude use with the
Australian robot and other robots? Anyway, why would a guide ring have
those rods or those "handles"?

A guide ring would be used with perhaps three robots and a control
station. Wouldn't all those items travel on the same vehicle?

The truck has reels for gas lines, but the welding cables are hanging.
Wouldn't a company that invested in automatic welding also invest in
cable reels? They would save labor and cables and keep the workplace
less cluttered.

anyway -- it looks to me as though at least some of the holes
around the ring have studs in them facing in towards the center, which
makes it's use as a tire bead setter less likely.

I wonder what they are for. Some sections have only holes. I think
they are to fasten sections of the band together or to add more hooked
rods.

The circumference of a tire doesn't seem to compress. I think that's
why it takes so much tension to seat a bead by pulling a rope around the
tread. Friction is a problem between a tire and a strap that stretches
under tension. It might not be an issue between a tire and metal band
that wasn't under tension and didn't stretch.

If the band can flex, pressure under a strap at the center would not
mean pressure at the edges where the screws are. The hooked rods would
transfer pressure across the tread to the shoulders. I suppose each
hooked rod could be pulled separately by a chain and a pry bar at the
hub hole of the rim.

A neighbor who has driven trucks for 30 years pulled in tonight. I
described the mystery ring and asked if it might be to seat the bead of
a truck tire. He said bands like that are used, and it's much safer
than squirting ether into the casing, igniting it from a few yards away,
and watching the tire fly into the air.

Having him recognize the photo would mean more than his response to a
description, but he was about to go to bed. I put a copy of the photo
on his steering wheel in case he leaves before I see him.


I see two oxygen tanks lying down, instead of locked upright as
they should be. A tank of some fuel gas (I don't think that it is
acetylene, so perhaps propane or natural gas) at the right front
corner. Acetylene would have to be strapped upright to make it usable
without a few hours of upright resting after being turned upright from
lying down.


The green tanks are painted for medical oxygen. One appears to have no
cover for the valve. Maybe it's empty, and maybe the refiller is good
at detecting damaged valves.

Wholly orange tanks are for refrigerant. It sounds to me like a
self-employed repairman. Truckers need roadside repairs, but I think
gas welding with a portable cart would be plenty. Long lines for two
kinds of welding make me think of farm equipment. It often needs
welding, and you may not be able to get a truck or cart within 30 feet.

Uh-oh, I don't know that the truck has any electric welding equipment.
I jumped to the conclusion that the blue box contained a generator and
electric welder. If that's wrong, it seems there are three pairs of gas
lines visible.

On the right hand side of that object at the front is what looks to me
like an exhaust pipe . I'd bet even money it's a welding machine , a big one
too !

I agree that rods look like they could get in the way of the automated
welder, the ring in the video did have a handle, although it was rotated 90
degrees and wasn't sticking out as far as the one in my photo. I was
thinking this ring could be for a different model than the one seen in the
video, or maybe it wasn't used with the automated welders at all, but was
still used as a pipeline welding clamp.

I'm hoping the person who first suggested that this was a welding ring can
answer your question about the rods.

A guide ring would be used with perhaps three robots and a control
station. Wouldn't all those items travel on the same vehicle?

reels? They would save labor and cables and keep the workplace less
cluttered.

Hard to say, he could have been transporting the ring without the need for
the other equipment, or someone else could have had other equipment on their
truck.

Since I haven't yet seen another ring just like it, I changed my answer page
to say that it's possibly used in welding, and also possibly used for
beading tires. I'll be out for most of the day but plan to do a little more
research when I get back.

Patent 4997020 is for a device where a metal band of several
sections
would be tightened around a truck tire to seat the bead. It says
putting a strap around the tire was an established method, but this
would result in asymmetrical pressure, due in part to friction
between the strap and the rubber.

1473 could reduce friction in tightening a strap. The hooks could
also be a means of compensating for asymmetrical pressure by
exerting pull between hooks across the circle.

I dunno...the patent device seems to be made of a series (at least
3)
sections that can overlap, so tighening the device reduces the
circumference. This thing seems pretty solid.

Some observations: the 'handles' are directly opposite that D-shaped
stain on the opposite side. It might be the bottom, with the two
handles on top at 10:00 and 2:00.

The truck seems to be a welder's truck....does this have anything to
do with welding? If not, could it be something he is taking back to
be
repaired?

Around the rim of the ring are 7 'rods' that extend beyond the ring.
Are the ends of these rods bent outward, or are there little 'knobs'
at the top? And between each rod are 5 small angled things, that
look
like they could be used to secure a flat plate on to the ring.

Hmm....I love a mystery, but less so when I know it might never be
answered.

The thing that's bugging me is that I feel like I've seen one of those
damn things somewhere and I have no idea where it was.

Wild guess here - Could it have anything to do with pipeline work? I
see a lot of trucks like this in the East Texas area, several right
here in the RV park we stay in, and these guys are doing gas/oil
pipeliune construction. Still don't know what that big ring is for,
but just thought I might throw in an alternative employment for the
vehicle.
