This jack (798) is standard equipment in a chemistry lab. It is used
to set up experiments where you might need to raise and lower part of
the apparatus e.g. a heating mantle.

789. The ball is gas filled to make it almost have zero gravity. This
makes it so light that it doesn't have enough gravity to develop
momentum. Therefore it takes a long time to start the rolling. Once
the rolling starts of course it will continue. I would wager that the
length of time it takes to roll down the ramp is not linear... that it
picks up speed as it goes along.

788 Button assembler.

786. Since Barr was a toy manufacturer I'm going to wager that that is a
device that determines the tire size for their toys. by adding or
removing rings it would control the size.

791 Maple tree corer for getting syrup. Or a soil corer for taking samples.

Well, those are my guesses.

I have seen this ball work and it does indeed continue to roll slowly the
length of the ramp.

789. The ball is "partially" filled with a very high viscosity liquid.

789: The ball is a thin metal shell. There's a lead weight in the
bottom, as if somebody had poured the shell 20% full of molten lead.
The weight is not stuck to the shell. There is also viscous fluid such
as STP in the bottom of the shell.

As the ball starts to roll, the contact point moves ahead of the lead.
It can't roll faster than the lead can slide on the viscous fluid.

This is a good set puzzle-wise.

791. a coreing bit, for taking samples from trees.

792. This is a lab jack, for raising or adjusting heights of stuff in a
chemistry lab.

788. Looks like some sort of press. Given the decoration and
coloration, I'd guess it's for candy.
792. Jack for holding scientific (chemistry) and physics glassware or
other apparatus during demonstrations or experiments. Used to support
distillation flasks, optical components, and other beamline equipment
such as lasers.

787 Yours looks so much like mine that I had to go look in my collection to
make sure it was still there. It is a saw-tooth set. The star wheel has
notches to different depths, for the height of the tooth. The thumb-screw
from the side controls how far you bend the tooth.
790 looks like a cutter for trimming the edges of wallpaper. It slides in
a track on a wooden straightedge. The little wheel does the cutting.

Given the name on the device, I'd say its a condom sizing machine used
in the adult film industry.

786: Postage scale
792: Used in chemisty lab

I've only seen the one.

Anyway -- posting from rec.crafts.metalworking as usual.

786) Hmm ... interesting thing.

Does the center post come out that far by itself when the
stepped disk is removed? It sort of looks like it is calibrated
as a scale (the more you put on it, the deeper the rod goes and
the higher the number).

Perhaps it is a combination desk ornament and postage scale
(reads in ounces).

The stepped disk appears to screw onto the collar through which
the rod protrudes, leading to the idea that it is a decorative
cover instead of a functional part of the operation of the
device.

787) This appears to be a device for un-bending something a precise
amount.

788) A wine press for one grape at a time?

The "screw" does not look strong enough to apply much force.
Perhaps it is for clamping a seal onto hot sealing wax?

Or perhaps it is for pressing a pocket watch case closed after
it has been opened?

789) My suggestion is that it is about half full with a highly
viscous fluid -- and the weight of the contained fluid is
greater than the weight of the ball half above the fluid, so
when placed on the inclined plane it only rolls as fast as the
fluid can flow around the inside of the ball.

790) This looks to have an old phonograph needle installed in it.

It *might* be a holder for sharpening the needle.

Or it might use the needle as a scribe of some form. I've seen
various tools (machinst's scribes) which used phonograph needles
as replaceable scribe points.

Does the part holding the needle rotate as the lever is lifted?

791) This appears to be a tool for taking samples of some substance.
I would suggest something like cheese. The big screw drives it
into the object being sampled, and the small half-hollow rod
allows withdrawing the sample from the screw.

792) A mini Lab-Jack. I've got two of the larger style, marketed by
Cenco. I've seen the smaller ones as well. They were used
where I worked both in chem labs for raising something to the
right height, and in optical labs for adjusting the height of a
lens or mirror on an optical bench.

It looks as though the top rod (in the upper photo) and the
bottom rod (in the lower photo) has been replaced with a
makeshift after the original failed from overloading.

Now to see what others have said.

Enjoy,
DoN.

They've all been answered correctly:






786. Postal scale, the top piece is inverted and placed on the numbered rod.

787. Saw set

788. Nutcracker

789. Snail ball, it rolls slowly because a small heavy ball is inside along
with a viscous liquid, the rate at which the smaller ball moves determines
how fast it rolls down the ramp.

790. Chicago wall scriber

791. Increment borer, for finding the age of a tree.

792. The jack is for use in a laboratory.

Selck made floor coverings. I imagine the disk part had a point. You
put your linoleum against a well and roll the tool along the baseboard
to scribe the linoleum with a line that will match the wall.

This is in response to DoN's question about the lever, and the tool's use on
linoleum. The owner of the wall scriber states:

The needle is in a round brass "lug" about the size of quarter but about
3/4" thick, the needle has a set screw either to replace the needle or to
set its distance out of the "lug". There is a screw through the lug with a
knurled thumb wheel to cinch it down. Evidently you can rotate the needle
slightly in or out by rotating the "lug". There are several index hash
marks cast in the chrome portion to gauge the rotation. Moving the brass
"lever" does not move it any way.

I have never been able to diagnose its use. It has two rollers on the
"bottom" to make it easy to roll along. I have always assumed one would
roll it on the floor. The needle would put a scratch on something that
would still require a cut. I have always assumed linoleum. The brass "arm"
or lever looking thing confuses me the most as I see no reason for it to
move or purpose for it. I assume it would rub against the wall, but it
would keep the needle a fair distance away from the wall if you were trying
for a dead on the money fit. If any one could come with the directions, I
would sure know just how it was used.

Not casting aspersions about the Swedes but if they are anything like
English potatoes: "Made of quality Swedish steel" is a somewhat suspect
appelation.
