1759: looks like an adze, for a woodcarver; could, however, be some
kind
of boat-caulking tool. If it had more metal parts or nastier wood
ones,
it could be a welder's chipping hammer...
Or, it's a nutcracker. I dunno.
1760: a divider, compass-like item with a center (but no center is
seen).
It is a lot like some drawing-instrument compasses, but the handle is
sideways, like it has to clear some obstacle. Maybe for visibility
in mapmaking or mapreading use?
1761: holder for circular-saw blades, fits a pegboard. I want one!
1762: souvenirs of aircraft flight certification?
1763: Guidance tool for working with pachyderms?
1764: the glass item is a vacuum bell jar, the ground surface seals
against a greased plate or gasket. The bracket is for holding the
top seal in place when you raise the lid, as you must to open the
vacuum chamber. It's a good dessicator, if you want to make
dried flowers (or powdered herbs). |

I don't think I have much of a clue on most of these this time around.
1759 - Something very strange indeed. At first glance, it would appear
to be a hammer-like tool of some sort, but the bit does not appear to be
particularly strongly held in place. Maybe what appears to be a wedge
securing it is actually a buffer or shock absorber of some kind, and the
screwed-in reinforcing plate and/or the through pins hold some internal
mounting? At any rate, I can't think of any especially likely purpose
for the tool.
1760 - Appears to be a specialized set of dividers or distance gauge,
presumably for laying out work. Maybe it was intended to be used when
producing electrical switchboards, although I would have thought that
was a dying art already by 1951.
1761 - The writing on the side seems to say "SWAY" something. I would
guess, from that, it's a rocker for some use, but no idea what.
1762 - Gauge for setting angles for something for various aircraft --
possibly for some part of a jetway (robotic walkway thingy) or for some
maintenance check on the aircraft itself.
1763 - Part of a set of bolos, used as a weapon?
1764 - Clearly some sort of laboratory apparatus, perhaps a specialized
burner for heating substances, or perhaps a device to separate
non-miscible liquids and permit the heaviest to be drained off.
Now on to reading other guesses...

1761 - saw something very similar on 'How do they do it' this evening, a
holder for silicon wafers during chip fabrication, used to lower them into
etching baths after the photo-lithography stage.

Posting from Rec.crafts.metalworking as always:
1759) A grubbing hoe made where there is a shortage of good
steel?
1760) An interesting version of a trammel -- fine adjustment of
the spacing of two points, with an unusual handle. For
scribing a line parallel to a straightedge. (Normally, they
are also for drawing circles and radii, but with the handle,
that would be awkward.
1761) If it had a curved cradle where the straight ends are, I would
suggest that it is for the purpose of tilting a steel drum or a
large bottle for emptying it controllably without having to
support the full weight.
Hmm ... perhaps for storing four 35mm movie reels (proably
enough to make a normal length film).
Perhaps with the hooks on the far edge, it could be for editing
the movie -- with scenes from various source reels hung from the
various hooks, and spliced together to a final reel.
1762) Presuming that the angles of the levels has not been disturbed,
I would suggest that it is for identifying the amount of list or
heel in a boat, to warn when it is getting close to a danger
level. (Or perhaps in the cab of a crane for similar purposes?)
1763) This looks like a rather serious "cosh" or "blackjack". Hmm
perhaps for the purpose of killing cattle for slaughter?
1764) O.K. This is a fairly small vacuum bell jar. It is mounted
open end down onto either a ring of Neoprene rubber or with a
very thick grease onto a flat steel or cast iron plate. A pair
of steel rods are screwed into the plate and clamped by the
clamps on the outrigger ends (which are common chem-lab type
clamps) of the top to hold it concentric with the glass. The
right-angle tube from the top is connected to the high vacuum
pump to evacuate the container.
There is also a valve between the tube and the stopper which
goes into the top of the jar to allow you to seal the jar and
then shut off the vacuum pump to save energy.
The reason for the large bottom opening is so it can be set down
on top of something intended for testing under vacuum without it
needing to be small enough to fit through the neck at the top.
(Also, this eliminates the uneven stresses of a fabricated
bottle bottom, which is typically of uneven thickness.
Ideally, there should be a cage of heavy steel wire around it to
contain the glass fragments should it fail.
I could actually *use* something like this -- for vacuum
impregnating dried out porous sintered bronze bearings and the
like. If the owner of it does not need it now that he knows
what it is for -- I would be willing to buy it from him.
Enjoy,
DoN.

for precise alignment of disks or rings. The pins may be pointed to
penetrate soft material or to find their way into small existing holes. |

Nope, no way. A compass wouldn't have two points. Could be a divider
(which does have two points), but why the odd way of adjusting it?

1760 I'm really fascinated/confused by this one.
I can't think of any normal drafting operation that this could be used for.
It can't be used to divide a line the way normal dividers are used because
the handle is in the wrong place. You'd be moving your whole arm very
awkwardly.
To transfer a distance from scale to drawing or from drawing to scale, it
would be awkward to swing it around, tightening the wingnut would tend to
move the whole tool, there is no third-leg (on the end of the handle) to
keep the mechanism horizontal and the points vertical. If you were using
the handle, your knuckles would be dragging on the drawing.
The points, while replaceable, are much fancier than the simple replaceable
points on a divider or compass.
I'd guess it is used to transfer a distance from one place to another. For
example, it might be set to some distance at some inspection reference
station, then carried to a workstation on a factory floor to be used to
verify the distance on a workpiece.

My guess:
it's a ring tool for lenses. The pins fit the holes in the lens ring holder,
and the tool can be adjusted to any diameter ring. Once set and in place, the
handle is used to initiate the rotation of the holder ring. It can tighten or
losen the rings.
I want one! |

I'd guess a spanner of some kind, maybe for optical components. It appears
that the two pin-holders are slightly bent in opposite directions (but that
might be a trick of perspective), which would support the notion of its
having been used in this fashion. |
