2191) Strange beastie. Since it seems to be attached to
a key ring, it might be part of a link to a belt hook for
something line a janitor's or night watchman's keys. The keys
will hold in place under normal conditions, but they can be
easily detached from the belt at need -- including what once
happened to a janitor at a school dorm. He was walking along
outside and saw a radiator hanging from one of the upstairs
windows. So, he went up there, put his key (still attached to
his belt) in the lock and turned -- finding it rather difficult
to turn. Then it turned, and he found himself sliding across
the room, dragged by the keys attached to his belt.
What had happened was that the room was one of two with a shared
door between which could be unlocked from both sides to allow
passage between the rooms. This was during summer session, with
few students, so lots of empty rooms. Someone wanting to give
the current occupant of that room a hard time had:
1) Unbolted the radiator from the steam pipes (summer, so
2) Tied the radiator to the doorknob by a steel cable.
3) Removed the door's hinge pins.
4) Left via the door to the other room.
He expected his friend/victim to come along, turn the key, and
have the door vanish across the room -- not to have a janitor
with keys attached to his belt.
The only reason that he was not pulled through the window and
down a few floors to the ground was that the door did not fit
through the window.
2192) Looks as though it is a tool for drilling a hole in wood from a
single side and then extending the hole rather quickly by using
the rest of the tool as either a file or a saw depending on
which edge was applied. Way too coarse for most metals, though
it would work on lead or other soft metals I guess.
2193) A black stone turned into a watch fob?
Perhaps a container for something?
2194) Looks like an industrial version of a dealer's "shoe" for some
card game -- Baccarat, perhaps?
Anyway -- intended to deal one card (or whatever) face down from
2195) A demonstration of complex linkages perhaps?
2169) Looks like a tool for popping out ball joint linkages or something
Might also be used for installing a press fit of some sort in
the field -- certainly not in a factory, but perhaps in a
Now to see what others suggest they are.
