Got one! 2923 is part of a manual-feed slide projector. The trough
holds a tray of slides, with one slot for each slide and one side open
so they can slide out horizontally. The moving parts are best seen
in the last picture, which shows them in mid-motion. The top and
bottom bars are guides and the middle one serves to push the slide
into the projector. Inside the projector the top and bottom bars are
connected to another middle bar that pushes the slide out. To advance
to the next slide you pull the knob out all the way and then push it
back in again. This also rotates a gear (seen in the top photo) that
engages a rack on the bottom edge of the tray, advancing the tray by
one position. The gray square is a shutter that is opened to let the
projection beam through; it might be manually controlled as well, or
it might be triggered by the changer mechanism somehow.
In 2924 the insulators seem to mark it as a high-power electrical
installation of some kind -- maybe a switching station of some kind,
not yet connected to the power lines?
As usual, no idea on the rast.
Mark Brader What is it about
Toronto Haiku that people find so
2923 I agree with MB on this.
2924 Guess... Test facility, to apply high electric fields or
lightning to a missile.
2925 Seems to be intended to slit or split the end of a specific size
dowel. I've no idea of what the specific purpose is.
2928 To ram a cork into a long necked, large wine bottle???

2923, toy tollgate for toy cars. The black thing is the camera window so
that the state PD can mail out tickets for talking on cell phone, etc.
2924, some kind of power grid distribution network. The insullators give

2926, blood lancet designed for use at blood drives at factories and

2927, no clue.
2928, totally no clue.

I need some help on the fifth item this week:
Rob, what do you prefer to have people do when they have something you
might be interested in?
I have some that apply specifically to small-shop machining, but which
are old or odd. Some, or maybe many members here will recognize them,
I think, but they're intesting nonetheless. You may or may not find
them worthwhile, but they should interest RCM members.
I would be happy to look at photos of whatever you have, you can send them to my
email address which can be found on my profile page. A link to my profile is
located a little below the last photo in each week's set.
I'll be looking forward to seeing your machining items. Everyone else here is
welcome to send in some pictures, I'm always in need of things to post.
2924. I have seen similar in Houston. Like this one, a stand alone unit
with no visible connection to anything. I was always under the assumption
that it was a training/practice installation for linesmen. Similar to the
tall small buildings that firemen train/practice with.
2925. Insulation stripper.

2923) An adaptor to run a magazine of 35mm slides through
a projector originally designed for being fed one
at a time. Not sure which, but it may be one of the
early Leica (Leitz) projectors.
It could be a stack loader, not for magazines, but I don't see
the pusher and follower.
2924) It looks like a switching station for electrical power
distribution, but I don't see the power feeds into and out of
it. Perhaps the lines are buried underground?
Or it could be an intersting and directional antenna array
of some sort -- really high power given the size of the
2925) This looks like a tool for stripping the insulation on a
heavy (likely rubber) jacketed electrical cord. Possibly
telephone line drop cord.
Spread the two handles, slip the wire in from the T-bar end,
close the handles, hook the fingers into the hooks, and pull.
2926) For puncturing a sheet metal container, I think. Maybe for
starting modification openings to housings for HVAC equipment.
(I've seen someone use a screwdriver for the purpose. :-) Not
exactly a neat hole, but sufficient to the purpose.
2927) Looks like it is intended to puncture and fold back a part
of the metal top of a container -- perhaps something like the
old automotive oil cans.
And it might slide down an upright rod in a table, which would
make it for puncturing something like juice cans -- V8 or the
2928) I think that this is a tool for drilling holes in the upper end
of furniture legs -- for mounting to the furniture via dowels
The wood part actually looks like a beat up leg blank which
has been modified to serve as part of a clamp.
Now to post this and then see what others have suggested.
