130 looks like a casting/blow mould pattern.

I played with these things in JH metal shop.
We would make an oil/sand mould from what is shown in your picture.
Usually the final product would be cast with the sand mould with
aluminum. For bottles, the mould would be somthing re-useable like a
"bondo" cast from the pattern. Oil/sand is typically for high heat
materials like metal.
The bottle was then made by heating a piece of plastic tubing until it
was all soft in a small oven. The tubing was then "clamped" between the
two halves of the bondo mould and before the tubing cooled. compressed
air was applied to force the tubing out against the interior of the
mould. Flash was then trimmed and viola! a plastic bottle.
BTW,
what do you do with your "collection" of stuff? It seems all these bits
and pieces would fill several rooms easy. You certainly could open one
of those "theme" resturants where they have the walls covered with these
kind of things....

Goes in cycles...and are always interesting to look at.
#130 looks like a master pattern for some sort of casting.
It gets pressed into the sand, leaving an impression, later filled
by metal
#131 A single-edged, razor blade injector (been a lot of
years since I used one...but I remember it well).
#132 a "dead center" for a lathe. usually mounted in the
tailstock with the cone end out. Don't know the exact taper, but
from the size I would guess it is a #2 Morse Taper.
#133 Looks like one of two support pullys for a clothsline.
#134 Hum...some sort of a drywall tool...maybe for pushing
the metal corner bead on an outside corner into place?
#135 Another challenging one. It looks like it COULD be
a precision weight of some sort. Or...it could be the flywheel
from an old floppy disk drive...Can't say for sure.

Correct.

Thanks, I knew that it was a center for a lathe, but didn't know the other details.

I couldn't find any similar to mine on the web, so I'm still looking into this one.

Yes, it's a mold for something common.

Yes, it's a pattern, but it's for a bottle so I'm not sure if the
metal part of your answer is right.

This one wasn't for clotheslines.

I'm still researching this one.

This object isn't a weight or a flywheel.

Thanks for the info on the patterns.
I've always enjoyed finding and collecting unusual objects, the more
interesting ones I have on many tables in my condo as conversation
pieces, I don't live with my girlfriend so I don't have to be
concerned about anyone else's thoughts on the accumulating tools. The
lesser exciting pieces get boxed up after being out for a couple of
weeks, so while I do have quite a few items in several rooms, I'm not
yet approaching the status of a hoarder.
I especially like discovering the ID of some of the more obscure
pieces, to me it's like a puzzle to figure out what they are and how
they were used.
I don't see myself opening a theme restaurant, but some day I would
like to display the better ones at a museum, university or other
similar place. Someone suggested that I put them in a book, but I'm
not sure there would be a market for it. For now I enjoy sharing the
collection with family and friends, and also on the net.

Are you sure it's a mold? It looks more like a pattern (from which
the mold would be made).

Yeah, I think those are all patterns to form a casting mold from. In
#11, the light colored part is the pattern for the part being cast,
and the black part is intended to make a recess in the mold, into
which a core will be placed (so the resulting casting is hollow). The
thin section heading off to the right is the sprue, the point where
the molten metal (or whatever's being cast) is poured into the mold.
ob woodworking, pattern makers were noted for being particularly
skilled & precise in shaping things from wood. There are some
funky tools (like corebox planes) derived from the pattern making
trade.

Yes, but I was thinking that the pivoting arm was used
as a brake - tie a rope to the eye and when pulled the
other end of the arm contacts the pulley. Hard to see
from the picture whether the arm is long enough or not.

For a pill bottle maybe?

I forgot to reply to this on my previous post. This pulley was used in a
different way than most people would think. It wasn't used for lifting
anything, I guess the pivoting arm could be called a brake since it's meant
to keep the rope from moving but it was more for tension. There wasn't a
separate rope to operate the arm, there was just one rope that tied to the
eye and also went through the pulley.

It was tagged "bottle mold" when I purchased it from an antique shop, but if
that's wrong it wouldn't be the first time that something I bought that was
incorrectly marked. Would this be used with a sand/oil mixture to make a
mold, or is there a different way it would be used?
A couple of months ago I posted some other objects that I was told were
machine tool molds, now I'm wondering if they should be called machine tool
patterns. They are numbers 2, 11, 12 and 13 on the page below.

You're correct that it's a bottle mold, but I'm not sure what type.

I forgot to mention that #135 isn't a tool, I would put it in a different
non-utilitarian catagory.

#131 holds razor blades and is used to inject them into
the razor.
#132 is a (prolly #2) MT dead center for a lathe.
#133 some kind of brake?
#130 could be a mold for injection molding.....
130. Unknown
131. Injector razor blade dispenser.
132. #2 Morse taper lathe dead center
133. Unknown
