I'd argue that the shapes favor belaying pins, and the wikipedia cite (and
others) say wood or metal.
1301 It is a lantern used in mines. I believe it is a "Sir Humphrey Davis
Safety Lantern or Lamp" The one I have has two fine wire mesh tapered
cylinders above the glass under the cover and below the vents are also
screened sothere could not be an explosion from the lantern. There is
usually a spring operated "striker" to light the lamp. I am currently
looking for a replacement spring.

Hey Rob. Are you sure about the last one? I don't think that a
concrete grooving tool would have open ends. You'd have to be pretty
fastidious about using the tool or cement would enter the open ends
and would be a pain to clean. That would eventually stop it from
rolling.

The owner sent a few more photos to me that have been posted on the site,
including a side view and a shot of the red glass ball:
http://puzzlephotos.blogspot.com/
Below is his description of where he got it:
"I purchased a "miscellaneous lot" of items in a plastic dairy crate at an
auction, kind of a grab bag assortment. In it were various hand tools, some
aircraft parts, (two old dashboard compasses), and this item, which was
inside one of those little felt bags that Crown Royal whiskey comes in."
I've been doing some research based on the guesses listed in this thread but
haven't had any luck so far.

Yes, they're belaying pins, the photo was shot in a maritime museum.
I still haven't been able to confirm the answer for number 1305, but the

I couldn't find one on the net to use as a link on the answer page, but
there is one exactly like it in the "Dictionary of American Hand Tools", and
the person who sold it to me also said it was a cement jointer. I guess
they had to hose it off really well after using it so it wouldn't get locked
up with cement, maybe that's why you don't see them anymore.

I've seen a number of other tools that do their intended job but have design
flaws of one type or another, and I think that is the case with this
particular tool.
As I stated before, this exact tool is in one of my books, and though I
couldn't find a photo on the web, there was this mention of it:
"Joints in the pervious concrete pavement were cut immediately after rolling
using a rolling groover ..."

I haven't worked much with cement but if this tool is as bad as you say it
is then it would make sense that you haven't seen one, they probably made
them for a year or two and then quit production.

Same here.

In the photo it does look like a mark of some sort, but it's just pitting;
there's not a single number, letter, or symbol on it.
So since I have some evidence that it is a rolling jointer and no evidence
pointing in any other direction, I'm going to have to keep my current answer
for now. If anyone finds additional information on this tool one way or the
other, please let me know, I'd be happy to take a look at it.

True, and most dedicated craftsmen don't buy tools that make their job
_more_ work.

1305: the diffraction grating and mount from a monochromator
or spectrometer. Jeweled movement: that "red ball" is
probably a ruby bearing that engages a micrometer-screw
driven surface to make fine angle adjustment (because of the
linear motion of the micrometer, it will read out the sine of the
angle).

I'm still a bit dubious about the tool being for cement work. I've
done my fair share of cement work and I've never seen a rolling
groover. I couldn't find a rolling groover anywhere on the internet.
I've seen plenty of rolling joint rakers, but never a groover (two
sided) nor edger (on sided). Besides the obvious cleaning issue with
the tool you posted, there's the very problematic question of how the
tool would function. The typical groovers are like sleds with curved
leading and trailing ends, and they have flat bottoms so there's
little worry about creating unevenness. Since concrete has aggregate
and is not a uniform material a rolling groover would create a divot
or hump every time it ran into an obstruction (aggregate) or soft
spot. You would have a lot of unhappy customers if you finished off
the nice flat work with wavy grooves/edges. Here's a link to
Marshalltown's groovers:
http://www.marshalltown.com/catalog/results.asp?SUBCAT=211
The designs are all the same, flat bottom and you push it back and
forth. I can't imagine any trade is slower to change than concrete
finishing - it's been the same material worked with essentially the
same tools for thousands of years. I also did a USPTO search and drew
a blank for a rolling groover. The tool looks like it has a marking
on the wishbone part of the handle. Do you have more information on
that? Thanks.

1302. Belaying pins. I know of these because I have seen them on the big
rigger sailing ships. But long before I knew of their use for rope, I had
read of another use for them by almost all sailors of that era. They were
also used as weapons. Indeed many pirates kept a couple of them on their
person when fighting. If the single shot pistols were fired and there was a
problem with a lost sword or a confined area, out came the belaying pins.
I would think a good whack or two from these belaying pins would take the
fight out of almost anybody.

Again, I actually know some of these this week.
1301. Safety lantern for use in flamable/explosive atmospheres. AKA a
"Davy" lamp (http://en.wikipedia.org/wiki/Davy_lamp).
1302. Belaying pins. Used to tie off or "belay" ropes on a sailing
vessel.
1303. Manual weed eater used to cut weeds off that are growing in a
parking lot. Looks like it has to be used horizontally rather than
vertically.
1304. Tuning coil and "cat's whisker" signal detection/tuning portion of
old "crystal" AM radio set. Making one of these work could sometimes be a
black art in low signal "fringe" areas.
1305. Looks like it might be a monochromater from a spectrometer (a device
that splits incoming light into its component wavelengths)
1306. Used for rolling expansion joints in concrete.

To get technical for a moment, I don't think this is a diffraction grating.
I rather suspect it is a prism. This was probably used in a UV-Visible
spectrophotometer.

Remember that Japanese fish hook that is pretty much identical to a

use, turns out it sucks for that application, then someone fishing

"Aha!" I'd sharpen it up and use it to cut pizza just to freak people

The fly in the ointment with that link is that it refers to pervious
pavement/concrete. That's a relatively new development and the tool
looks to be at least 50 years old judging from the patina.

HI,
As several others have noted, #1305 is a diffraction grating. It is
mounted in a precision rotating mount. Note the two screws on the back
to set the vertical and horizontal tilt. The "ball" is probably the
mechanical contact with the "sine bar" ( not shown) which causes the
grating to rotate in a very controlled fashion. This drives rotation
mount such the sine of its angle of rotation changes linearly with the
angle of the input which is often a from a stepper motor.
Diffraction gratings are often on removable mounts so different
gratings can be swapped in and out of the spectrometer. On the bottom
is a kinematic mount for so that the assembly can be replaced back to
its exact previous position.

Ah-ha, a very specialized tool developed to do a common job on a
highly specialized and unusual concrete application. This special
concrete would only work in frost free areas.

O.K. Posting from rec.crafts.metalworking as always.
1301) Some kind of fuel powered lamp, with the structure
at the top a way to vent the hot gases.
1302) Belaying pins. Were placed through holes in the rail
of large sailing ships were needed to allow lines to be looped
over the top and the bottom in a figure eight pattern. They
could be moved from an area where a line had just been released
to where another needed to be secured.
And -- in certain situations, they could be used to "calm" an
upset crewman. :-)
1303) This looks designed for breaking up ice buildup caused by
spinning tires so you can get unstuck in the winter.
1304) An early "crystal" radio, with the usual crystal (gelanna (sp?)
held in poured lead, with a "catwhisker" positioned by the knob
pointing to the upper right. Except that in this example, the
crystal has been replaced by a much more modern germanium diode
connected between the two thumbnuts.
Tuning was accomplished by the sliders moving contacts above the
coil.
The more modern version still had a real crystal under the
catwhisker. Headphones connected to the two binding posts to
the left, and the antenna to the one to the right.
1305) Now this is an interesting one -- and I suspect that the glass
is a diffraction grating used to break the visible light up into
a spectrum just as a prism does.
The fine adjustments allow you to place the desired color over a
sensor or whatever experiment happens to use it at the time.
I don't see the red glass ball -- but I suspect that it was
intended as an indicator that the incoming light was hitting the
right area on the diffraction grating.
1306) Designed to either roll something like window screen into a
groove on a frame in the construction of window screen
assemblies.
Or -- it could be to cut something (fabric, screen, whatever) on
a hard surface.
Now to see what others have guessed.
Enjoy,
