[TheForge] Speaking of hammers

Mon Apr 19 00:53:00 2004

As I recall from past conversations on theforge he was having trouble
scaling it up.

I also recall someone saying his or one built on his valve scheme got hot
enough to make oil smoke.

I have a couple Beche patent drawings and they follow a similar valve scheme
to most contemporary hammers, even Massey hammers. It seems around the late
teens or early 20's everybody went to rotary valves with multiple ports.

Massey patent drawings from the 20-30's are hard to tell apart, valving
wise, from Nazel, Beche, Chambersburg and a number of others that escape my
memory. From the early 40's there's a Massey patent for a spool valve that's
so complicated I don't see how it works at all let alone is an improvement.
I didn't bother downloading that one.

I'd like to take a look at yours if you have the patent number I can look it
up and save some bandwidth.
