STEAM
HORSE FOR STREET RAILWAYS
Mr. S. R. Mathewson of Gilroy, Santa
Clara county, Cal., has recently devised a new motor for street
cars, an illustration of which is given herewith. The following
description, by the inventor, will explain its operation: "
The design is to make a, machine resembling a horse in form, so
as not to frighten the horses on the streets. To this end the
form shown is chosen. The motive power is steam, generated in
a tubular boiler of from four to five horse power, located inside
of the horse and forward of the cab. This drives a rotary engine
of my own patenting, which is geared to the driving shaft of the
machine. I also propose the use of gas as fuel, so as to do away
with smoke. The steam is condensed in cold water carried in a
tank of sufficient capacity on top of the cab. Gas is compressed
in suitable tanks to a pressure of from 80 to 100 lbs. per square
inch, and is used as fuel. The boiler is so constructed as to
receive a supply of hot air to feed the flame the gases from which,
after passing around the boiler. are conducted around the engine
to prevent loss by condensation. The water is forced into the
boiler from the condensed steam chamber. The engine is provided
with a brake capable of stopping the apparatus within a space
of twenty feet, while under a speed of eight miles per hour."
The inventor points out that the engineer
could easily control the machine, and also collect fares and perform
other duties usually done by conductors. He claims that the cost
of running the apparatus will not exceed one dollar per fifteen
hours, that it may be very cheaply constructed, and that its use
would be productive of a very large saving to street car companies.
He also states that the weight of the machine will be from 2,800
to 4,000 lbs., and that it will run at from 4 to 20 miles per
hour. A cow catcher is provided, and suitable devices arranged
for attaching cars.
A signal bell is fixed above the horses
head; and a lantern in front serves as a head light to give warning
of its approach, when the machine is running on dark streets at
night.
