291. Eraser shield
292. Some sort of ratchet tooth
293. Metal flower sculpture
294. Multi-head cutter
295. Corrugated fastener for joining two pieces of wood, like parts of
a picture frame.
I know what #290 is: an insulator. Not sure exactly what
type, ie. where used. Electric fence maybe. The size tho
suggests something heavier, telephone line or power line?
The two metal ends do not connect inside. The ceramic
body exists to hold them, in a fixed distance apart, yet
not connected electrically. The bizarre shape, with
ridges, is so that high voltage corona is somewhat reduced,
air currents over those ridges will tend to stir the air
and break up an ionized air channel. So I'll guess it's
more for a power line. I don't see any mounting -- both
ends are designed to accept a bare wire -- so now I'm
wondering what it would be used on
#291 is a draftsman's eraser shield. You put that over your
drawing and apply your eraser in one of the holes, to erase
just the item you want. (Once upon a time, people made
technical drawings with pencil on paper.)
#292. Something familiar about it but it escapes me.
293. ditto. Artificial metal plant?
294. I've never, ever seen anything like this.
295. That's the blade out of a fancy potato cutter. But
where's the rest of it? How did it attach?
We used to play this game at Christmas time. Everybody had
to buy somebody else a wierd strange gift and the recipient
had to figure out what it was. If they couldn't they might
have to wait a year to find out.

290 is a ceramic insulator
291 is an eraser shield. Besides drafting, is was used for typing--in the
days before whiteout and deletion paper.
293 looks like a collectible piece of barbed wire
295 is a corrugated fastener--they were driven into the end grain of wooden
boards to hold them together. A very common use was on the end boards of
wooden produce boxes. These used to be called by a politically incorrect,
One you had recently, that I no longer see--an iron meteorite. I ran across
one for sale at a flea market last weekend.
294 is a type of "wrench" used to remove steam pipe fittings.
i always saw them used to install and remove the union that goes
on the inlet of a steam radiator in home heating systems. The nipple
had two little ribs cast on the ID of the pipe that the tool would
engage in the cutouts. The steps are for different sized nipples,
and the square section is for a wrench to turn it with.
Can't remember what these are called, though...
Nope... wrong name.
A piton is hammered in place (frequently damaging the rock.)
This 284 gadget is essentially a set of cams. They can be
rolled to narrow their profile, placed in a crack in the
rockface, and then expanded. They don't damage the rock.
All the best,
290. Alien TP roll holder. (they have wavy butts)
291. Mistake selector.
292. Rubber band tensioner.
293. Stupid goth kids trying to worship the Anti-Santa.
294. A Device.
295. Metal corn cob--only not with corn.
Posting from rec.crafts.metalworking:
290) Electrical insulator. Supported by a wire around one of the
grooves. It might be an insulator for connecting a long-wire
antenna to the downfeed wire. If I could see a parting line
anywhere, I would suggest that it be a feedthrough insulator for
going though a window or the like.
291) Erasing shield for an old typewriter without correction ability
292) It looks intended to wedge a sliding window from motion.
Perhaps a sliding rear window in a pickup truck, based on
the size. If it were larger, I would think that it was for a
sliding glass door.
293) For hanging some kind of foodstuffs to cure. if it were smaller
I would suggest that it was an early and nasty version of
barbed wire. It looks as though the spikes are cut free from
the shank and bent out.
294) A stepped wrench for unscrewing something -- perhaps some kind
of valve seats? Rather ugly casting, in any case, with no
apparent effort to clean off any flash.
295) I wish I remembered the name of this. It is intended to join
two pieces of wood edge to edge or end to end. The near edge is
driven in, with the stress along the width in use.
