PICTURE – PATTERNS FOR MODEL

By Staff

Mr. Earl Nelson of 4052 Seventh St., Minneapolis, Minn., tells
about the Model Engine he built and which is pictured in this
issue. Ed.

I waited some time for the pictures you will find enclosed. They
were taken by the best photographer I could get, he is head
photographer at the University of Minnesota.

This engine develops about one-half hip. at moderate speed and
pressure. It is built a little different than the ordinary engine,
in that the cylinder is square, on the order of a Corliss but still
‘has a still valve.

You will note that the steam goes in the center of the cylinder
on the top and comes out the same on the bottom. Also note that the
cylinder cocks are built in the cylinder and drain into the exhaust
pipe in the bottom.

Thus engine is not just an engine. It is built as neat as
possible and with care it. runs noiseless at any speed.

I am also sending you a picture of patterns for a one-quarter
hp. I am building and pretty much on the order of the one-half
hp.

I have cylinder and valves of Mr. Gaines engine from Glenco,
Minn. I have bored the cylinders, refaced the valves and seats,
made new pistons and rings and valve stems. They did look sickly
when I started on them but they will survive.

Well Mr. Ritzman, I think you should have a little of my
background. I was born in a machine shop and took to mechanics
quite early, and along with that I was interested in steam engines
of which I have built many kinds and still enjoy working: with
them.

Back in the year 1922 I was stationary engineer for the Soo Line
Railroad but lost out when the depression struck. I stood high with
the company but did not go back as I went into the artificial limb
business. I worked at this for over 20 years. This gave me the name
of Nelson Machine and Joint Works. At one time my work was over the
world but now do very little of it. I like my hobby best.

I am getting too old to work hard but like to do things that
must be right. Things that take time to make right. I am over 70
years old and have lost speed but still retain accurate
workmanship.
