#274: Pinstriping tool.
Yep. for sure. I used to use one of these years ago for pistriping
lucite sght gauges with lacquer paint.

Thanks, I'll have to do some research on this.

I am sure others will point out that the Roman numeral L stands
for 50
XL would give 40
XLIX would give 49

Oooops. You, of course, are right. My brain was telling me the L was 5
for some reason...

I've been going to a web site that translates to and from roman numerals,
since they are kind of tricky if you don't use them very much.

You might be right, it is just part of a camera, I'll post a photo of the
whole piece in a day or two.

272. Some kind of clamp, but I don't know what for.

273. Lathe dog.

274. Pinstripe painter. Fill the bottle with paint, invert it, and roll
paint on with the wheel. If not for paint, then some other liquid, maybe
adhesive.

275. Thing for throwing clay pigeons when shooting skeet. (Save the
poor, defenseless skeets! ;-)

276. Camera iris.

277. Tee-nut for wood or particle board.

Now, I'll go read the other answers on rec.crafts.metalworking...

It's not a shutter, but it is part of a camera.

The shutter is behind the iris. The iris is first opened to the
calculated/selected F-stop, then the shutter opens briefly.

What we're looking at here is the iris.

No, unfortunately I can't find one quite like that and I must admit that I'm
only speaking from what I've heard others call them. Lathe dogs generally
have a tab that is either bent to go into a slot on a faceplate or straight
to be driven by a bolt mounted on the faceplate. I've always heard the kind
with a fork like the one pictured called grinder or grinding dogs but I
don't know why. I can find examples of grinding dogs with 2 forks on them
but I must plead ignorance on the differences.

The round head screw on the side is for attaching to something that would
go through the hole, which does not have a passage into the nozzle.

That fits with the pinstriper theory. The screw would be to clamp an
adjustable edge guide that you can use to follow an existing stripe or a
contour on the body of a car. Sort of like using a rip fence on a circular

I just wanted to assure you that item 274 is indeed a paint striper as
many have indicated. I have one that I bought long ago for the
exorbitant price of $4.79. I still have the instructions. It is
titled the Master Double and Single Line Paint Striper Model No. 1100
and was manufactured by the Embee Corporation of Springfield, OH. You
are missing several of the brass wheels and spacers that allow
different line widths and double lines.

O.K. A complete shutter assembly, missing only the screw-in
front and rear lens elements.

And the cylinder is specifically for a pneumatic shutter release,
a hose to a rubber bulb squeezed by the operator.

A very slow shutter, too. Speeds of 1/4, 1/2, 1 and 2 seconds,
plus T and B (T=time -- shutter remains open after first actuation of
the squeeze bulb until the second actuation) (B=bulb -- shutter remains
open as long as the bulb is squeezed, so you open the shutter with one
hand, and trip the flashbulb with the other.)

At a guess, the 'I' (Instant?) setting is simply the shortest
time that the shutter is mechanically capable of -- maybe 1/8 second or
so.

I think that the cylinder on the otherside is a dashpot -- a
piston moving in a closed cylinder with a calibrated leak -- useful for
slow mechanical timing.

Enjoy,
DoN.

277 isn't drywall - it is the backside of a wood piece that is bolted to something.

The Iris could be a shutter for a color spot or bright lamp - or carbon arc lamp to shut
down the volume of light to the subject. The real question is how tough is the item -
is it very thin - then camera - if reasonable thick then lamp or a projector (carbon lamp)
limiter. or on/off switch.

I planned to pinstripe a model I am doing but got interrupted by excessive work

The heads seem to be the same or like that on the auto one - massive ink supply.

There are those who say that it's bad form to subtract anything
but the next lower "denomination" from a given symbol, i.e.,
XL, 40 plus IX, 9, gives 49. But you can't do VL for 45 or IL for
49. I think XC works for 90, but not IC for 99 or VC for 95.

I've always wanted to see a step by step example of how a long division
problem with a couple of "not too easy" numbers is solved in the Roman
numeral system. Can someone show me/us one?

When I was a kid, there was a series of books either by Time-Life or
Bell Labs/Disney or something, with all kinds of interesting scientific
stuff. In the volume on numbers, there's a cartoon of a guy trying to
do long division in Roman numerals. ISTR that after filling up a whole
page (like filling up a whole blackboard in a comic strip) the guy
gives up. :-)

The ancient Hebrew numeral system is even simpler as only addition is
needed to determine the full value, there's no subtraction of lower
denominations located to the left of higher ones. If interested, see:

O.K. A complete shutter assembly, missing only the screw-in
front and rear lens elements.

Iris, not shutter. It's adjustable to control the aperture, not open &
shut to control exposure. An iris like this can't be fully closed,
for one thing.

I said "complete shutter *assembly*". That is shutter blades,
timing mechanism *and* iris diaphragm.

The iris is only part of it. Did you bother to look at his
latest set of images of that one item from many views? It has the
provisions for setting several (quite slow) shutter speeds.

The shutter happens to be open, so what was initially
photographed and presented in the puzzle was only the iris diaphragm,
but he has the whole shutter assembly there -- except for the lens
elements which screw in behind and in front of the iris and shutter.

Enjoy,
DoN.

Just posted some new photos:

http://puzzlephotos.blogspot.com/

277 One of three parts of a nut bolt system to fasten something on a
plaster wall or whatever this is called in English.

I don't think that there is three parts to this one, but it's something
similar for fastening.

It is definitely not a wall anchor. (although it could be used for one if
put into place before assembling the wall! ;-) )

Cheers!

276 looks like a shutter (to an old camera? film equipment? I dont
know)

It's not a shutter, but it is part of a camera.

The shutter is behind the iris. The iris is first opened to the
calculated/selected F-stop, then the shutter opens briefly.

What we're looking at here is the iris.

Correct, except on this old camera part the shutter is in front of the iris.

If this is this one:
http://pzphotosan52.blogspot.com/
then it's clearly a shutter, since they say so right on the page.

The "T" is "Time", the "B" is "Bulb", I don't know what the "I"
is (maybe instant?), then 1/4, 1/2, 1 and 2 have to be shutter
speeds. And the cylinder on the right for the remote bulb. The
little pointer on the bottom is proabably equivalent to F stop.

Oh! I see - in the original photo, all we saw was the iris, in
the back view. On my monitor, all I see for the original is black.
Also, in the back view, you can see that that lower pointer is
coupled to it. So the assembly is both the shutter and the iris.

Cheers!

Hey, I can get a pic of one of those on a large lathe at work.

There's also one on one of the lathes where I work. But in the
pic #275, the points didn't look like wheels to me, and it doesn't
fasten down.

The background is all dark, because the shop is shut down for the night.

But you can see the source of my confusion! :-)

Yep! What you photographed is a steady rest, not a lathe dog.
It is intended to have telescoping arms extend out of the three arms
shown at 120 degree intervals. The knobs on the end of the arms extend
the inner ones to contact the workpiece and support it on center as it
rotates.

The lathe dog shown in the puzzle clamps onto the workpiece with
the square-headed screw, and a pin from the faceplate fits between the
two legs to rotate the workpiece with the spindle while it is supported
between centers.

Enjoy,
DoN.
