872. Google says they made toy trains so I guess a lap counter of some kind.
The spindle with the worm gear would have to be connected to something and
each rotation would advance the dial one digit.
873. The metal reinforced front edge indicates it's designed to plough into
something. For clearing snow off your drive perhaps.
875. Another variant on the self clamping log grapple.
876. Google says they made typewriters but other than that I have no idea.

I thought Royal was in business before typewriters came along like
Remington was, but now I'm not so sure. From my typewriter repair days,
I remember seeing old Royal models where the keys were underneath the
paper and struck the platen on the bottom. You had to grab the platen
and lift it all the way up on its hinge so you could see what you just
typed. Those models were VERY early and the typewriter came along
around 1870, so the date looks right.
angle, I'm guessing it's a tool for aligning typewriter keys for a
model of typewriter that even a museum probably can't find anymore.
872: Let me try a reasoned guess...
It is a pendulum turns counter intended to accumulate rotations about an
It only counts modulo 10,000 so it probably isn't used as an odometer or for
counting revolutions of any fast-moving machine.
In use, in the case, the reading is not visible. This suggests that it
isn't used for control or measurement. That leaves some sort of audit
It seems to be well-made, suggesting that many were made, but not a very
large number of them.
The case is unsuitable for exposure to the elements, so it is used in an
indoor, benign environment. This lets out it being used as a turns counter
for a Ferris Wheel.
I therefore guess that it is used as a audit counter for turnstiles
(diagonal axis, not vertical axis) used to verify the number of people
entering (some sort of theater or exhibit). The agent of the person
expecting a royalty could lock the case into a recess in the turnstile, and
come back later to retrieve an independent count of turns.
If shafts are available, normally you'd use something like a
veeder-root counter for this sort of thing. There are variants that are
not resettable and variants that count only in the positive direction.
OTOH This Lionel device can count both forwards and backwards. So
wherever it's put, you don't expect much back-and-forth action but
It seems from the pictures that it's padded in a little box in use.
There is no obvious attachment points on the little box, which is most
I was thinking more along the lines of something you put in a package
to figure out how many times it flipped over when it fell off the back
of the UPS truck, the early 20th-century equivalent of a ShockWatch.
Lionel made instruments for the Navy in WWI and WWII. A Navy engineer
might want to know how many revolutions a big, slow-moving engine had
made during a certain period. I think the padded box was designed to be
slipped into place on the end of a slowly moving crankshaft.

An interesting collection of images:
872) Hmm "Lionel" used to make children's electric train sets
(among other things). However, this is something else entirely.
Looking at it, and assuming that the worm gear is fixed in
place, it is designed to count the number of times the hanging
part with the dial has passed through 360 degrees (a full turn)
within the frame.
Adding the case, it *could* count the number of times that round
case has rolled a complete turn. Knowing the OD of the case,
one could calculate the length of the rolling paths -- but the
straps could introduce errors, unless that case goes in yet
another round object. I get about 14" per roll with just the
length setting the diameter. Looking at the case, I would have
to guess about 18" per roll, or two rolls per yard. Since it
can count to 99 -- or perhaps 999 or 9999, depending on how the
lower scale behaves, we have at least about 150 feet before it
873) For removing light snow from a sidewalk or path.
874) Perhaps for blocking a hat? More to expand within something
than to clamp something like a vise would do.
It looks as though the leadscrew is of opposite hand threads on
either side of center, so if it is a single leadscrew connected
to the two knobs, then it would expand or contract equally
around a center point.
875) For lifting a block of ice -- or a carcass in a butcher's shop?
876) Other than that it changes the distance between the sole plate
and the steel rod at the top as it is adjusted, and that it has
a roller (or perhaps a pair of them) at the right hand end, I
really don't have a clue.
877) The rubber band is not original -- but it might have had a
spring around there to keep the jaws closed as the rubber band
does now. Or maybe it was to be wound about with rawhide to
clamp more firmly as the rawhide dried?
At a guess, the user sat on the board and used a file, handsaw
or other hand tool on whatever was held in the jaws.
Now to see what others have guessed -- if the news articles are

874: From the complexity and materials, I'd guess something from a
ship. Maybe part of a periscope?
875: Picks up something; bundled straw or rolls of paper or something
876: A failed attempt at a parallel cutter; until the device was
manufactured, no one realized the blades were in the plane of the tool
and hence wouldn't work.
