If the Ford Museum had simply said: Edison invented the first practical
incandescent light bulb, I would have no problem. But it was the glee a couple
of them took in saying: EDISON DID NOT INVENT THE LIGHT BULB that rubbed me
the wrong way. Henry Ford would have fired both of them on the spot.
I said that Edison invented the light bulb. I don't give credit to his
predecessors for inventing the light bulb, because theirs didn't work. The
Patent Office requires an invention to be useful before it can be patented.
Non-working attempts don't count, and in this case were disallowed by the

Hi Ger:
Most auctions take about a 25 - 30% commission rate; however it also depends on
how many phonongraphs you are planning to sell at the auction house. If you
decide to sell just 1 or 10 the higher the commission rate. If you sell your
whole collection like 50 or more then the commisson
the auctions that I attend locally, charge the buyer 15%, the sales
commission are negotiable based on the type merchandise, and the potential
amounts realized. On smaller items (-1000) it is usually 30%. But it is
totally negotiable. A whole collection valued at 500k may go for as little

I am trying to locate a set of four ball bearing type wheel casters for an
early VTLA. The part is a brass cup with a pressed on shoulder. The small end
of the cup slides up into the leg of the phonograph. In the bottom of one of
the cups is the remnant of a ball bearing ring. The open end of

Were they only used on the VTLA? I just parted out a VV-XIV and saved those
casters and related parts. In fact, they are still attached to the legs.
Let me know if that would be of any use to you.

Good point Al about ebay. Auction houses could make up to 45% on items ( 30%
plus 15%) that make under $1000 There was an auction house near while I live
(now defunct) where they would keep 50% commission on items you consign that
total under $100. On top of the 50% the auction house also
I've heard many people say that Edison didn't do ANYTHING worthwhile, or simply
took credit for others' work.
That is interesting because Edison stopped using patents and started using
trade secrets because of all of his work that was stolen. That is why we have
so little written
From tinfoil phonographs to light bulbs, Edison made things that were
practical and worked.
If one does not realize the difficulty of Edison's inventions then one has
not attempted to duplicate them. Has anyone ever played with a reproduction

Thanks for all the replies related to what to see at Greenfield Village. I
never thought this question would spark such a spirited debate. I just

a great trip and hopefully we'll find some treasures along the way.

I like the yoke assembly of the Model O reproducer with the tiny -160 screw
that goes into the stylus bar and holds on the washer with .019 arms that no
one makes today because it is too complicated. 100 years later one would
assume those items would be easily made. Steve

Very interesting but the M feedscrew I had to duplicate was examined under an
optical comparator and there was no doubt the thread of the original 1892 part
was a 45º buttress thread. The depth of the thread is only 0.007 so the lathe
setup is crucial. I will have to check the
I must agree. I had to have a feedscrew rethreaded some years ago, and the
machinist told me he had to use an old lathe of his dad's to make the buttress

Having just made a batch of half nuts for Homes and Triumphs I respectfully
submit that Home and Triumph leadscrews do not have a buttress thread, but
