823 looks similar to some old autoshutter-timer for cameras
824 is it used for casting small parts? http://en.wikipedia.org/wiki/Casting
825 a whatthehellisthis
825 second guess: caliber for inner side of tubes?
826 to squeeze the wather out of clothes?
827, 828 same as 825

I came in too late this time (hectic life right now) to answer before
the answers were posted. However I'll make come comments on a couple of
I don't believe the "Finishing nails" part, as all finishing
nails that I have seen have at least some bulge for a head.
Looking at the shaped points, I find myself wondering whether it
could be electrodes for a TIG welding gun.
The numbers on the dial could be sizes, or materials.
Did you change the text on the "questions" page when you posted
the answers? I don't see a question left -- you seem to have it fully

828 was the only one which I was likely to really get before the
answers came up. I've seen them advertised many times, but never
actually handled one.

823- some kind of dial-o-matic container where you dial the internal
bin you want to line up with the little spring-loaded lid. But to
hold... pencil leads?
824- 2-man sledgehammer for... hammering big sledges.
825- used in the maintenance of strowger switches. How? What, you can't
tell I'm guessing?
826- Yet another kind of cotton carder.
827- You turn the center knob, it pulls the legs up into the device,
causing the 3 circular pads to grip... something.
828- I want to say a scintillometer but the level blows that theory...
824. The two handles are weird. I can't see two people having the
right coordination and you wouldn't need two-person strength to swing
that. I'm guessing it's used for standing on a rail and hitting
squarely in a perpendicular directions. Maybe for removing railroad
827. It looks like a beading machine for circular tops. A can closer?
My 16-pound maul has the momentum to split logs much better than a
10-pound hammer. I have made a 50-pound hammer to drive fence posts
quickly and without damage. I can't imagine handling anything more than
50 pounds alone.
In the days before hydraulic tools, a 71-pound hammer would have served
important functions. The men would pick up the two-handled hammer
close to their bodies. In letting it fall, they would watch to keep the
head from tilting to one side. The coordination would be as easy as
putting down a table without spilling a cup of coffee sitting on it.
An ancient two-handled hammer has been found in a limestone quarry in
Egypt. The head is limestone. I imagine it was for driving wooden
wedges. If you tried to drive a wooden wedge under a big stone block
with a little hammer, you would damage the wedge but not move it.
If someone did swing a tool that heavy I bet you I can guess his first
name, "Sir!" And don't leave off the exclamation point if you know
what's good for you. ;)
I'm not sure I understand. Are you saying that it's movement in
operation was straight up and straight down? Someone mentioned tamping
earth, but the present day tools for compacting earth are more like 20
pounds. Having such a heavy weight wouldn't speed things up much. Two
guys with two 20 pound tampers would move more quickly. The side faces
are also chamfered/rounded, so I imagine those would be the business
Okay, but this isn't Egypt and it wasn't used for building pyramids.
The tool is probably a hundred or hundred and fifty years old, right?
When stone masons split rock, they use iron feathers and wedges, not
wood wedges. It doesn't make much sense to have an iron tool and wood
wedges. I would bet dollars to donuts that it's a railroad tool used
for nudging ties into place and straightening out the track.
I wouldn't be able to swing a 50-pounder. Mine is a pipe with a lead
weight. Inside the pipe, at the bottom of the weight, is a piece of
tire tread. It's heavy to lug around, but if I put the pipe over the
top of a fence post, pick it up, and let it drop, it will transfer a lot
of momentum to the post. A lighter hammer would tend to damage the end
of the post and bounce off.
Sledge hammers are usually but not always used up and down.
There's a limit to the kind of tamping you can do with a 20-pound
tamper. The force from the blow of a light weight doesn't last as long,
so the material being struck may simply spring back. It would be hard
to split firewood with a tack hammer.
I wonder where to find out what tools crews used.
As an iron hammer could be used on wood ties, it could be used on wood
wedges. The limestone hammer surprised scientists because it could not
be used on metal.
The size of a hammer can be important in splitting rock. If the hammer
is too small for the job, all you can do is damage the iron wedge.
I have seen a photo of a two-handled hammer. It was a group posing in a
foundry. Two men whom I would call "Sir!" are holding the hammer high
as if about to swing down.
I wonder if it was to deliver a lot of momentum to a mold in order to
make a casting pop loose.
828. Sight level for finding a place on the same level on a distant
object as one's present position?
You stand somewhere, and look through the sight level. When the top or
internal level is centered, what you're looking at is at the same height
or level as you are. I'm not sure how the level is viewed, via a mirror
or another spirit level inside the device.
One made my first boss a millionaire. He used a sight level to find out
if a farm he thought to buy was on the same level as the coalfields west
of it. It was, and he made mucho bucks selling the strip mining rights.
He also insisted on back filling and contour restoration. Once the earth
had settled, he sold the land as building lots and also built some
houses on spec.
Bring back, Oh bring back
Oh, bring back that old continuity.
823. The closest thing it reminds me of is a split-shot dispenser in my
fishing tackle box. It would appear to hold ten types of thing which are
about an inch long and a few mm wide. I think sewing needles might be a bit
too long. Fuses might fit but there aren't ten types as far as I know. It
would do nicely for split-shot though.
824. Two handled hammer for driving wedges into trees or for splitting
826. Carding machine for wool or cotton.
827. For fitting milk bottle tops or similar.
