I need some help with the fourth one this week:
2772 wee wooden cask - hopefully full of "medicine" ..
that the loyal Saint Bernard delivers via his collar ..
Great series - I'm stumped on them all ..
The 4 inch glass container cannot be a lamp shade of any kind -
too small & shallow. The shape lends itself more to a lamp oil
reservoir .. a small decorative supported lamp.
Posting from rec.crafts.metalworking as always.
2767) Hmmm ... I wonder whether this is some form of sliding
joint pliers, or a fixed pivot?
If the latter, it is for gripping and removing something of
a specific size.
If the former it can be adjusted down to quite small things, and
the fixed blade could cut something quite close to the surface,
so it might be for cutting off projecting nail heads. (That
groove in the moving jaw has to be to clear something, but I
don't know what.
2768) This is a millstone. I believe that it is the fixed lower
stone with the channels designed to guide the ground grain
through the center hole.
The driven upper stone should have a square or otherwise keyed
hole to allow it to be driven by the mechanism -- usually a
2769) This looks like a support for benchrest firing of a rifle to
allow aiming and firing the rifle without muscular vibrations
influencing the aim point. The forestock rests on the 'Y' with
the adjustable height screw, and the handgrip on the padded
platform behind it. It is adjusted to put the height of the aim
point where you want it, and then the rifle is slid around until
the lateral point of aim is also where you want it, and then the
trigger is very gently squeezed until it fires.
2770) This is an interesting object. It bends the point of aim
downward (with the mirror). I'm not sure whether that is a
half-silvered mirror, and thus allows you to see something in
line with the frame or not.
At a guess -- it is captive on some kind of video shooting game,
or perhaps a psychologist's test apparatus.
However -- I don't see that the trigger actually does anything,
unless there is something missing -- perhaps part of the frame
to which it is attached by the vertical wand.
2771) Looks sort of like the fuel reservoir for an oil lamp, missing
whatever should hold the wick.
2772) Hammer head for a carnival "ring the bell and win a prize"
game? I don't know whether the other face is better for
striking than the visible one. But it looks too lightweight to
do anything serious with.
Or could it be a dispenser for something like Bingo balls or
some other form of game token.
Now to post and then see what others have suggested.
My best guess is that 2770 is a device for training to use a crossbow
pistol. The Swiss are big into crossbows. By keeping the image of the
pendulum round, you know the device is level left/right, and is aimed up at
a slight angle determined by the mirror. The trigger does not do anything
except get you used pulling on the long hard trigger of a crossbow with out
moving the aim point or changing the left/right roll angle.
No luck yet on the 2770 (the pistol shaped tool), some progress was made on
the company logo but the device is still unidentified. More information and
the rest of the answers can be seen at the link below:
Hopefully we'll get an answer for 2770 in the coming weeks.
2770: Hammerle designs and installs machinery for automated
manufacturing. If they used a lot of tubing of the same diameter, this
tool could clamp to the top of a tube so that one worker could hold it
vertical while another welded it in place. If you had light coming from
below the tube, you could keep the pendulum centered, like aiming a
rifle with a peep sight.
Somebody suggested that it was to align and drop a cylinder. My idea
comes from that suggestion, but I think you'd pull the trigger to
release the tool and move to the next tube.
I just added your theory to my list of possible answers, I'm still 50/50 on
whether it is for holding a cylinder for some reason or if it's for pistol
practice. Today I sent two more emails to companies in Europe, one named
Hammerli, and the other Hammerle. The first is an arms company and the
second makes roll leveling machines. Seems like there should be a similar
tool on the web but so far I haven't found any.
I see drawbacks to my theory. I envisioned tubes at least a couple of
feet long. In that case, a longer pendulum would work better. Would
somebody need to set 4" tubes vertical? Also, without damping, it would
be slow to use.
2770 looks like a quality control device to eyeball a hollow
manufactured item for centeredness, roundness and smoothness.
The light will be outside the gun with the shield as a diffuser and to
remove other reflections. The mirror centers the image of the pin in the
sight. The pin swings which would give one a shifting reflection to show
up irregularities. The top of the trigger sits proud of the platform and
serves as a quick clamp and bolt/carefully shaped washer holding the the
spring/piston assembly below would also serve as a key to hold the item
being examined in precise alignment.
My wildest guess would have something to do with laser mirrors... but it
seems more likely it has something to do with a machine part.
