Reviving the Quincy
This past summer I obtained the
design information and some patterns for the model of the Quincy
farm engine. This kit was offered some
years ago, and then disappeared. The kit had detailed castings
for the crank case and flywheels, but was mostly bar stock from
there. Lone Star Engine Works is completely
re-making this kit, offering a much richer casting set.
The Quincy is an engine with several
interesting features. The bore/stroke
is 1.5"/2.2", the flywheels are of heavy cross section,
9" dia. This is a horizontal hit-miss governed, igniter fired
engine with a speed control plus
it has a spark retard/advance control. Cooling is liquid, using
a water jacket & liner.
A pump kit with coolant resovior
will be offered to compliment this
very interesting engine.
Below is a picture of a beautiful
Quincy 2 Hp I saw at Coolspring June '09.
The Model
02/21/2010 - Building of the Quincy
model has been completed, and it is running reliably. The governor
is behaving well even though the engine is still tight.
Breakin is in progress, and a set
of old style nuts & bolts are being made. The drawing package
is in progress, and hopefully will be ready in a month or two.
Additionally, the prototype for
the coolant pump is in progress. Below are some pictures of the
model so far.
The Engine
The Swan 25 Hp
The Swan 25 Hp engine being scaled is the fine
example at the Cool Spring Power Museum. It has been measures
by Ynzie Madema of the Netherlands.
This engine is an early (around 1901) oil field
engine. It is a 4 stroke, with a cross slide and hot tube ignition.
Both intake and exhaust valves are operated by cams on the side
shaft, and is throttle governed by a flyball governor, also off
the side shaft. The Swan was designed to be run on natural gas.
The flywheels are bolted on to tapered flanges which tighten against
the crank shaft.
Lone Star Engine Works now has a Barber
Coleman #3 Gear Hobber. We make the gears for our kits in house.
This allows gears to be custom made for
each engine.
