846. Chain Saw Blade Sharpener
845. Styrofoam building form to be filled with concrete. They're
stacked like blocks to build the house shape and then filled with
concrete. The styrofoam acts as the insulation for the house.
846. Chainsaw sharpening device.

841 Transfer screws - used to locate a hole opposite a tapped hole in
two parts to be assembled. You screw the transfer screw into the
tapped hole pointed side out and assemble the parts, tap on the part to
be marked and the pointy end of the screw makes a mark opposite the
tapped hole.
842 Some kind of gunner's quadrant use to sight in a larke artillery
piece.

not 100% certian, but it looks like the PolySteel brand...

841- 3/8-16(tpi) center-indicating screws for transferring the center
of a screw-hole to another part. The large item is both a holder and
driver.
842- the markings on it indicate its used on a plane to find the true
bearing, but to compensate for wind? For use near the poles where a
magnetic compass has a significant deviation from bearing?
843-
844
845- poured concrete foundation form with pipe/wire holders

In the days of yore when Fire Watch Towers were in use they
used a similar if not the same type of device. If I recall
correctly, they had a bit more distance in between the sites
though.

hi,
# 841 looks like 3/8" X 16 screw threads. The five screws are used to
transfer positions of holes. One screws them into threaded holes with
the point sticking out. The holder tube has a small socket one the end
to help screwing then in. Lay the undrilled part of this and tap it
with a hammer. Where to drill is marked.
# 845 is a form for concrete used at a corner. After the concrete sets,
the foam is left in place as insulation
Enjoy

According to R.H. <[email protected]>:

Posting from rec.crafts.metalworking as usual.
841) A set of transfer screws.
The '16' is the thread pitch -- 16 threads per inch.
The function is that they are screwed into tapped holes with the
male hex and the point up, and adjusted to just barely have the
point sticking up. Then the mating part is placed above the
original part, and slammed with a soft-faced hammer so the
points mark the center of all of the holes to be drilled so
bolts will pass through them and into the threaded holes in the
first piece.
The hex socket on the projection at the left-hand end serves as
a wrench to screw the transfer screws into the workpiece.
The knurled ring at the other end is a cap (as stated) to keep
the set of transfer screws stored in the handle for future use.
Note that the other end of the screws is not a hex socket as
usual, but rather a round hole, designed to clear the male hex
to allow the screws to be stored occupying less space than
otherwise would be necessary.
Five screws are sufficient for most tasks of this nature.
842) An aircraft navigation instrument. Probably a form of sextant
for sighting the sun or stars (depending on the time of day or
night).
I don't see provisions for entering the aircraft speed or the
wind speed, or I would consider it to be for determining true
heading and speed.
843) Hmm ... given the mounting, I think that it may be to mount on
a roof (multiples of them, not just one) to break up caked ice
which is sliding off the roof so it does not come down in as
large and as heavy a single piece, and thus so less damage is
done by it.
844) This, I believe to be a device for marking the amount on a
check by embossing, so the check can't be erased and changed to
defraud the company writing the check.
845) This looks to be a part of an architectural model -- in this
case a curved alleyway with multiple gates.
But -- it might be some kind of gutter for controlling the flow
of waste water, with the gates serving the function of blocking
solid objects from entering the flow.
846) A file for re-shaping saw blade gullets.
Now to see what others have guessed.
Enjoy,
DoN.

Oh yeah.
843. Retainer to keep burning logs from rolling out of a fire place.
Normally used in pairs.
