1441 could be a steam whistle maybe a multi pitch?
1442 Guessing some kind of machine for preparing wool seperating it out and
lining up the strands.
1443 bad angle on the picture but maybe for taking the top layer off a road
ready for new tarmac.
1444 maybe a device for stretching material taunt over a drum or for
furniture.
1445 empty lipstick holder?
1446 nail extracter the lever mechanism would give extra grip to the sides.

First try at this so be nice.

1441) This is used to graph the pressure in a steam engine's cylinder
vs the stroke. Working from the first photo, the cylinder on
the left is spring loaded and rotated by the string wrapped
around the groove just above the support arm. The string is
attached to a point on the linkage which travels a distance
just a little short of the circumference of the groove.

A piece of paper is clipped under the two long fingers shown on
the back view in the second photo.

The bottom of the right cylinder (in the upper photo) is screwed
onto a steam port (replacing a plug which normally lives there).
Increase in the pressure lifts the black arm and draws a line in
the paper.

The spring in that cylinder is changed out to change the
full-scale pressure so the pen moves close to the full height of
the paper. The photo of the similar instrument shows one of the
spare springs out in the open, and two more in the storage box
along with what looks like a ring to change the length of string
for a full stroke.

I wish that I could remember the actual name of the device, but
it is used in the design phase to maximize the power from a
given stroke by tuning the timing of the valves. It can be used
to check everything later during preventive maintenance as well.

I've read about these -- but this is the first time that I have
seen good detailed photos.

Thank you.

1442) Hmm ... a cotton gin perhaps? Or for processing flax or
something similar.

1443) I think that this is the tool used to move linked Jersey
barriers to change lane assignments. I've seen them on use
both in construction areas, and in bridges where a certain
number of the middle lanes are shifted to be one direction at
one part of the day and the other direction at another part, to
correspond with the traffic patterns.

1444) To clamp the end of a ribbon (steel or other material) with
a thick end piece for installing it is my guess.

1445) A punch for cutting out circular pieces of a fairly soft
material. Perhaps for making holes in gaskets, or perhaps for
making something like the valve pads in English construction
concertinas. I think that the diameter of the punch is a bit
small for the latter use, however. What is it -- about 3/8" ID?
The shape of the sharpened edge suggests that the intended end
product is the circular punch-out, not the hole.

1446) A tool for picking up something heavy with a round projection
on the top. Lifting the handle close the jaws on the
projection. I guess that it could be used for something softer
than steel (such as wood) if you could live with the
indentations made by the jaws.

Now to see what others have said,
DoN.

1441 - This is rather obviously a specialized pump of some sort. The
bottommost handscrew connector is evidently designed to attach to some
standardized spigot or similar mechanical connector, while the plunger
mechanism appears to be some adjustable pressure regulator (presumably
adjusted by hanging various weights from the free end of the long
crosspiece and/or changing springs). It would seem the cup would fill
up when the pressure exceeded a certain fixed level, if I'm interpreting
the patent drawing properly.

Perhaps this is somehow used in a brewery to obtain a sample of the brew
being brewed for testing or tasting purposes.

1442 - Device used to separate out flax strands (to eventually produce
linen thread/cloth), possibly? It could also be a carding machine for
wool (probably not cotton in New York!), but there doesn't seem to be
any automated means of removing the cleaned wool from the spiked drum,
nor do the spikes look sufficiently numerous.

1443 - Funky construction/mining equipment. Maybe this is used to shift
Jersey barriers around, sort of like a giant zipper might do if it
zipped concrete walls. Whatever it is, I'm not sure I want to try to
maintain it!

1444 - Maybe a valve/valve spring manipulation tool for old L-head
engine valves?

1445 - This seems to be a nice little punch, I would guess for leather.
The retractable blade also permits easy stripping of the punched-out
holes should they become stuck in the blade.

1446 - Tongs to grip...something. The notched jaws suggest that
whatever is gripped possibly has a vertical hanging rod or cable, which
is attached to a somewhat larger shaft or toggle.

1446

It doesn't look good for pulling nails. There's no leverage, and the
claws wouldn't squeeze very hard.

I wonder if it's to pick up a cover. For example, in my town each house
has a water meter in a sunken box with a cover at ground level. If you
didn't want kids casually removing the covers, you could make the covers
flat except for the head of a rivet in the center. The rivet would fit
snugly in the hole but have perhaps 5 mm of end play.

The meter reader could used a screwdriver to pry the rivet head up, then
use 1446 as a lifting handle. If he steps on the rivet after replacing
the cover, the way to remove the cover won't be obvious. Anyway, a kid
would need a screwdriver, pliers, and a strong grip.

Yes, it might be for something like that, the only text that I saw on it was
"Pat. Applied For", so unless someone can find the patent its exact purpose
will remain a mystery for now.

A few hours after I posted the answers, one of my friends sent me the patent
for the tire lifter, it can be seen here if anyone is interested:

1446 is NOT a puller, since there is nothing pulling. It looks like
some sort of tong..similar to a Rail Tong for carrying train rails.
How long is it? Considering how beefy the arms are, I think its for
carrying iron ingots or something.

Put definitely not for pulling nails.

maybe for a coarse fiber as for rope.

Yes, I agree that it's more of a lifter or carrier, puller probably wasn't

pulling.

That sounds reasonable. I posted yesterday (but it doesn't seem to
have gone through) that this is not a puller...its a tong, similar to
a Rail Tong, but too short. Your idea sounds very reasonable...a
lifter for some sort of cover with the head of a bolt on the top,
almost flush with the surface. The thickness of the arms of this thing
makes it resist twisting while holding a heavy weight...something that
would come in handy while lifting a metal cover. And the T-grip
resembles the grips on the tools that plumbers use to turn off
underground main valves outside houses.

O.K. That is the machine which I was remembering. I used to
see it when we drove from the DC area to the Mystic Seaport Museum in
Connecticut once a year to help with the festival.

IIRC, there were even two of these in use at once, with one
following not too far behind the other, to shift two full lines in a
single pass -- quicker than a two-pass requirement as covered in the web
page. There was also one of these in use not too far from where I live
in VA during some construction -- but it and the linked barriers have
gone elsewhere now.

There's others that are even smaller and actually drive more or less
sideways to move the barrier an entire lane width.

It might be a way to lift covers from a road or plant floor.

In my town, 7" iron covers in roadways provide access to water valves.
Each cover has a notch on the side to get a tool under it. Dirt can go
through that notch. Dirt might end up covering the valve. If instead a
cover were designed to be picked up by the head of a bolt in a
depression in the center, there would be no notch to let dirt in.

The manhole covers have a notch on each side, presumably to insert hooks
or prying tools. I think they weigh 200 pounds. Somebody could get
hurt if a tool slipped. In 1987, the wastewater industry was the most
dangerous in America, largely due to injuries handling manhole covers.

If the tongs in question could be used to lift 100 pounds, two workers
could use two tongs to lift a manhole cover by bolt heads in depressions
at opposite sides. The inventor may have found it safer than other
methods. Also, tamperers would have to work in pairs and have tools to
grab the bolt heads in the depressions.

We generally use two tools to seat solid tires on wheelchair rims, but
that gadget looks like a heckuva lot better than what we use.

We have a commercial rig to do it by rolling it around the circumference
between the tire and rim. I think it's even more difficult to use,
especially on molded plastic wheels with the truncated pyramid-shaped
solids.

So called snap on tires can be a cast-iron SOB to mount.

I can clearly remember mounting solid rubber tires on cars without
any problems or tools. I did this about 70 years ago, on model
cars. The tires were about 1/4 to 1/2 inch diameter. HTH.
