American Geared Locomotives - Historical Background:
Like so many technological advancements, invention is often derived from
need. These interesting geared locomotives were conceived and designed
by men working on site and looking for better ways to transport logs as
quickly as possible on temporary rails over rough terrain. Ephraim Shay
was one of these men and the story starts with him.
Ephraim Shay (1839-1916) designed the first Shay locomotive and
patented the type.
Ephram Shay (right) studied to become a school teacher and taught in New
Jersey and Ohio during the late 1850s. From 1861 to 1864 Shay Ephraim
served in the Western Theatre of the Civil war, under General William
Tecumseh Sherman. Upon his discharge in 1864, Shay married and moved to
Michigan he established a general store and sawmill and was running a
logging business to supply the mill.
In the early days of logging, the loggers would transport the logs down
the rivers to the sawmills. When no river was available or when the
trees near to the river had all been harvested, they used ox and horse
drawn sleds in the Winter to haul the logs out of the forests. When
demand increased, crude railcars pulled over wooden rails set to a
26-inch gauge were used to haul out more and even bigger logs.
In 1876 Shay realised that a steam powered locomotive would greatly
help his business and allow him to haul more logs and become more competitive. He started off with a very crude and simple twin cylinder locomotive, but soon. Shay realised that
the dynamic force of conventional locomotive pistons on either side of
the loco proved to be too much and damaged the track curves.
He thus set about designing a solution that applied an equal amount to
torque to each side of the locomotive. In 1877 he hired William Crippen
of Cadillac, Michigan to build a boiler and cylinders that were
connected to the axel of the little loco by a belt-drive.
Shays design was not patented and Crippen went on to produce the
locomotive for the local industry. The Lima Machine Works in Ohio was
requested to build the locomotive by James Alley as Crippen was over
booked. Again as there was no patent, the Lima company produced the
locomotive and a few variants for the logging business.
Shay modified his designs according to his needs, but in 1880 he needed an
upgrade. As Crippen was too busy, Shay contacted the Lima Machine works
company and they worked with him on his redesign.
A Lima Works engineer, John Carnes, came up with the idea of powering
each axel of both trucks using bevelled gears situated outside the
trucks on one side of the locomotive. The gears were connected by
horizontal shafts that were subsequently connected to a crankshaft
driven by the steam powered cylinders, vertically oriented above.
SN-6 was a duplicate built for Milton J. Bond who had seen and was impressed by Shay s locomotive. The SN-6 was the first of 2770 Shay locomotives built by Lima.
Shay finally realised that he had something interesting here and he
filed for patent on March 30th 1881. This was his
Golden egg as it was the Lima works that would be building the
locomotive and he would be paid royalties for every one made. His patent covered the concept of using gears to drive the axels. A patent that covered many forthcoming locomotive designs.
He spent his later life promoting his locomotives and in 1901, at the
age of 62, Ephraim Shay sold all of his stock in Lima, thereby
completely ending links with the company. Shay kept on inventing and
lived out the rest of his life in Harbor Spring, Michigan.
Here we look at the 3 most popular geared locomotives of the late 1800s
and early 1900s.
The Shay Locomotive:
The classic Shay loco as we have come to know it is consisted of 2 or 3
vertical steam cylinders positioned on the right side of the engine
just forward of the crew cab. The piston rods were attached to a "crank
shaft" similar to that used in today s automobile engines. Attached to
either end of the "crank shaft" were drive shafts that extended to a
gear box on the outside of each wheel. The left side had no gearing or
cylinders. The boiler is located off centre and to the left of centre of
the entire frame. This was necessary for the location of the cylinders.
They were manufactured with either two or three
cylinders. The three cylinder models were used on the larger and more
powerful engines.
Models with two, three, or four truck sets were manufactured. More
trucks meant more distributed weight and thus more powerful locos could
be built. The two truck models carried their fuel and water bunker at
the back of a single frame for the entire locomotive. On the three truck
models, an additional tender with its own single driving truck was added
to the basic two truck locomotive frame. With the four truck model, the
tender was longer and was supported by two driving trucks.
The first Lima factory built Shay that was a two truck Class "A" sold to J.
Alley Co. for $1,700 in 1880, with two others being sold that year. The
last Shay built was the three truck Class "C" locomotive (sn-3354) sold
to the Western Maryland Railroad in 1945.
The Climax Locomotive:
Designed by Charles Darwin Scott - Spartansburg, Pennsylvania. Patented
by George D. Gilbert. Gilbert, who was a relative by marriage of
Charles D. Scott, was an design engineer for the Climax Manufacturing
Company. The locomotive was first manufactured by Climax Manufacturing
Company and subsequently by Climax Locomotive Works, both of which were
located in Corry, Pennsylvania. It was built between 1888 and 1928.
The basic Climax consisted of 2 steam cylinders whose piston rods came
out of the cylinders and attached to a transmission located under the
centre part of the engine frame. Connected to front and rear of the
transmission were drive shafts which ran along the centre line of the
engine below the boiler, cab, and fuel bunker. The drive shafts were
connected to gear boxes in each truck. These gear boxes supplied power
directly to both wheel sets in each truck.
Models with either two or three truck sets were manufactured. The three
truck models were used on those engines that required more power and
more fuel. The third truck was powered and carried a tender (similar to
those on "rod" engines) to carry additional fuel and water.
The Heisler Locomotive:
The first locomotive of the Charles Heisler design was built in 1891 by
the Dunkirk Engineering Company. The design was patented by Charles
Heisler in 1892.
The Heisler consisted of 2 steam cylinders positioned in a "V" under the
boiler about 3/4th the way back from the front. The piston rods came out
of the cylinders and attached to a "crank shaft" located under the
centre of the boiler. Attached to either end of the crank shaft were
drive shafts. The drive shafts were located below the centre line of the
engine. On the two truck models, the drive shaft attached to a gear box
located on each truck s wheel set that was located furthest from the
centre of the engine frame. Power was then supplied to the other wheel
set on the truck with an outboard tie rod connecting two wheel sets
together. This tie rod is readily visible in the picture above.
In terms of speed, it was the fastest of the 3 most prevalent geared
steam locomotives depicted here. It also had the fewest numbers
manufactured of these type of locomotives.
Models with either two or three truck sets were manufactured. The three
truck models were used on those engines that required more power and
more fuel. The third truck was powered and carried a tender (similar to
those on "rod" engines) to carry additional fuel and water.
Bachmann & Rivarossi Geared loco models:
There are a few model companies producing geared locos. On30 locos are
very popular in the US and G scale Shay locos are also common in many a
garden layout. You will find good brass models and also live steam and
miniatures too.
Bachmann produce HO, On30 and G scale Shay locomotive models and are
perhaps the most popular manufacturer of these locos. They also produce
a Climax model.
Rivarossi produced two Heisler Locomotive models, a two truck and a
three truck version.
The Bachmann HO scale range consists of HO scale models from North
America. HO are 1/87 scale models, running on the same 16.5mm track
gauge as OO scale models. The Spectrum range are also HO and N Scale
American prototypes but feature a greater level of detail and improved
mechanisms.
As well as producing painted unlettered locos - ready for personal customisation, Bachmann produce Shays in the company liveries for
Greenbrier & Elk River, Ely Thomas Lumber Co., Weyerhaeuser Timber, Cass
Scenic Rail Road, W.M. Ritter Lumber Co. and WVP&P Co.
As well as producing painted unlettered models, Bachmann produce Climax
locos in the company liveries for Moore-Keppel & Co., West Virginia Pulp
& Paper, W. M. Ritter Lumber Co. and Clear Lake Lumber Co.
Rivarossi has produced the Heisler in two truck wood burning and oil
burning models with the following liveries: McCloud River, Georgia
Pacific, Coos Bay Lumber, West Side Lumber Co., Potlach, Pickering and
Boise Cascade. The model was produced as a three truck model for Lehigh
Navigation Coal Co, St. Regis Paper Co. and Cass Scenic Railway.
The Shay was one of the most unusual steam locomotives ever conceived.
Designed to power logging or mining operations, this standard gauge
workhorse features a steel or wood-style cab appropriate to prototype.
Only four remaining operational Climaxes represents the last Climaxes to be used in
revenue service, eventually ending its illustrious industrial career in
the late 1960s. The standard gauge prototype still operates in tourist
service on the Durbin & Greenbrier Valley Railroad in Durbin, West
Virginia.
Again, we see independent trucks with universal joints and sleeves on
the central drive shaft. Bevelled gears drive all the axels.
Another slow mover. The movement of the piston rods set at steep angles
driving flywheels and gearboxes under the loco is very interesting to
watch. It has a very slow operation, but again with plenty of torque.
Rivarossi Two Truck & Three Truck Steam Heisler HO Scale:
These models were first produced in
the 80s and then updated at the end of 2002. In 2003, Lima was forced
into liquidation and in October 2004 Hornby acquired the assets of Lima,
including Rivarossi.
These Rivarossi models, produced in the early 2000s are made with an
all-new body that completely eliminates moulded-on detail. All of the
piping, sand lines, air lines, and more are separate details.
Blackened wire grab irons and handrails add to the realistic effect.
There is also a solid-brass whistle, pop valves, bell, front number plate
and photo-etched builders plates. And check out the other new features
like flush-fitting cab windows, optional headlight styles and working
knuckle couplers.
Inside that beautiful body lurks a tough, new drive that works like a
real Heisler! A can motor and new gearbox are connected to a super
replica of the V-2 "motor engine," so the crankshaft, rods and valve
gear move like the originals.
Driveshafts transmit power to solid-metal worm gears on one axle, and
side rods power all of the wheels just as the prototype did. Best of
all, the models are DCC-ready so you can plug in your favourite decoder
and start running.
A larger weight and an optional traction-tire-equipped driver set are
included to improve pulling power. Plus, the trucks have been carefully
engineered to provide all-wheel electrical pickup and still take
incredibly sharp curves with ease.
Perfect for any industry from logging to coal mining to industrial
switching these new models are offered in both 2 and 3 Truck versions.
Each is fully assembled and factory painted. Various road names are
available.
The Rivarossi 3 Truck model depicts a large standard gauge three truck
machine, and is quite impressive.
The underlying shell is enhanced with many added details- fine black
wire handrails, coupler cut bars, air brake pump, reservoir, and piping,
with the smoke box number plate, bell, whistle and safety vales in
brass.
The working motion is a treat and the model is powered from a motor in
the cab and bunker which drives the trucks using the central drive shaft
with universal joints, as per proto type; the gearbox is hidden in the
firebox. The loco sports a good plain satin black finish with dark
graphite smoke box.
PLEASE NOTE: Due to the small edition size and the great demand for this item, allocations are expected to occur.
