308. Gauge add-ons that clamp onto a framing square for laying out stair
stringers and similar.

309. Body dolly used with a hammer for shaping sheet metal, particularly
on cars.

310. Perspective is screwy, possibly a cutter for making tapered wooden
pegs or for sizing a dowel.

311. Torture device and/or drilling guide of some sort.

312. As noted previously, the C.G. of each piece is over the piece
below.

313. Looks like a small hacksaw, perhaps specialized for cutting a
particular type of material. The blade appears too wide for it to be a
coping saw.

314. Not sure, looks expensive.

308 Clamp on stops.
309 Draftsman spline weight (duck, whale, knot)
310 Inside view of a pencil sharpener
311 Gasket punch
312 One could overhang any amount, given enough blocks (1/2 + 1/3 + 1/4 +
1/5... is infinite)
313 Perhaps a saw, file, or gapping tool, but have no guess for its exact
purpose.

312 One could overhang any amount, given enough blocks (1/2 + 1/3 +
1/4 + 1/5... is infinite)

On paper this is true, but in real life it doesn't seem like anyone
could get the top piece offset by more than two or three lengths.
According to "Omni Games", "for three lengths you would need 227
pieces", and that's probably calculated using the exact fractions.
When actually stacking them, it works better to pull the pieces back
about an 1/8 of an inch, otherwise the structure becomes unstable very
easily. According to the same book, for a ten length offset you would
need 1.5 x 10^44 pieces!

I've searched the web looking for sites that show people stacking wood
to get the most overhang, but all I could find were a couple math
related sites with no pictures. Anyone know of a web page that has
photos of folks stacking things in this fashion? Seems like it would
be a good classroom or scouting activity.

Here goes nothin',

308. Don't know official name, but they are placed on a framing square to
layout stair treads.

309. A dolly for metal working. It resembles my heel dolly, but with more
rounded corners.

310. Don't know what this one is, looks like the material is brass, no size
given.

311. Looks like a leather (or gasket) punch with extra "spikes", possibly
for a fastener, maybe a snap?

312. The way the pieces are aligned makes it hard to tell the size of the
pieces, that is probably intentional. My only guess is that the pieces get
smaller as they go up.

313. Miniature hacksaw, very handy.

314. Haven't a clue, although based on recent posts I might hazard a guess
that it is photographic in nature.

The pieces are all the same size.

314: Curta Calculator. Made in Lichenstein. This is the smaller of the
two sizes which were popular with "Time Speed Distance" sports car
rallyists (like SWMBO and me) in the pre-electronic calculator days. I
still have mine in the closet. It has a hole in the bottom plate because
I built an motor driven cranker for it so that each time a speedometer
cable driven microswitch clicked off a hundreth of a mile the Curta got
cranked one turn and added in a preset minutes/mph factor to a running
total. Varying the car's speed to keep that total matched to a stopwatch
kept us right where we should be in time.

312: the mathemetician's answer would be that it represents the infinite
series 1/2, 1/4, 1/8 etc.

308. Is near to my heart.

I put a copy of the ad I just purchased on eBay at
http://hofstadparkhill.com

The two-piece set of gauges was a device marketed by my great
grandfather. When his son Robert passed, my brother and I collected
several bits from the estate. I purchased all of the bits for these
gauges at the estate auction, the firmly entrenched bidder finally gave
when he saw the look of determination in my eyes.

I captured several of the patent documents, some of which my son Patrick
has set for display. Many of the flyers, some of the tooling he used to
manufacture these, and several sets, of several varieties of the gauges.

They clamp on the framing square, what you can't see in the ad, is the
gauges are tapered just so, so that where they are set is quite nicely
set to the edge of the board. The longer gauge - with an attached tongue
was the unique feature. It was a simple scale with numbered marks. If
you want a 5-sided figure, you set the mark to "5", and the angle was
set. If you wanted an 8-sided figure, you set the mark to "8", etc.

My great grandfather John Parkhill built homes in Rochester. Grand
victorian homes with spires, and a variety of architectural features.
Dormers, ... I can't name them all.

Years ago in "the wreck" I sent out a couple of copies. I've since
disposed of 90% of the units. It was a sad moment, but it was clear that
800lbs of memories wouldn't do anything but sit & rust.

I still use them. They were functional 100 years ago, and today. I even
have a couple of the framing squares my great grandfather used. One I
passed down to my eldest son. One I hope stays with the family for
another century.

I think 311 is a hollow punch for cutting washers from leather- the
teeth would give reference marks for the larger punch so that the hole
was centered in the washer.

Five of the objects have been correctly identified so far:


308. Brass stair/square gauges

309. This one was marked "body iron", as several replies have stated
it's for body work on cars, I'm still trying to find one like it on the
web.

310. Pencil sharpener

311. Cobbler's/leatherworker's punch

312. There is more overhang in this stack of wood than you could
normally get, though with nothing to compare it to I guess it's hard to
tell. I'd like to change the question here to: What design feature was
used to maximize the horizontal overhang?

313. No correct answers yet, it wasn't made for cutting but was used
circa 1890 for another purpose. Thanks to Bill for submitting this
one.

314. Curta Mechanical Calculator, thanks to Mark for sending in this
photo, and also for the surveyor's double prism optical square, from
last week's set.

312. Assuming no glue, some sort of fastner was used ...

The center of gravity of all the boards above the top
right corner of any individual board is to the left of that
point.

Also plausible:
An interlocking joint was used.

It is a trick photo and the table is not level, the right side
is higher than the left. Or the camera is looking down
on the stack.

There is airflow from the right which provides pressure
to hold the stack up.

One more possibility.
The boards are not rectangles.
They are triangles with the base to the left and the

Correct, the pieces aren't triangles but you've got the right idea,
they are wider on the back end and thinner on the front.

Hey ob,

Can we have a little better "size" description for # 313. I first
took your description to be an overall measurement, but looking more
closely I see no "teeth" in what is apparently the blade, so my
thought is that is just the blade that is 3-1/4". True?

Take care.

The overall size of #313 is 3-1/4" and the "blade" (just a very thin
piece of blued steel with no teeth) is 1-1/2" long. Probably not much
use for this one today, though over 100 years ago it served a useful
purpose.
