THE MEANS AND APPARATUS FOR GENERATING MOTIVE POWER."
This Invention relates to improved means and apparatus for generating motive
power, the combined use of the power generator and motor (or apparatus for
giving off the power), as herein after described, being the essential features of
this Invention.
When the power employed for driving the motor is steam, the generator will be
a steam boiler with furnace and flues, with water feed valve, float, index lever, and
balance weight for showing the height of the water in the boiler, safety valve, and
steam stop valve, the said feed valve, float, and index safety valve, and stop valve,
being in combination or being separate and of ordinary design and construction; a
steam pipe attached to the stop valve conveys the steam from the stop valve to the
motor.
The boiler will be fitted with a self acting damper, consisting of a metal cylinder
on a hollow frame with a disc of india rubber, the steam being admitted into the
cylinder from the boiler by a pipe, the steam acting on the india rubber disc
forcing it upwards; on the top of the india rubber disc is a metal plate carrying a
pin which acts on a lever of the third order pivotted to a bracket on the cylinder;
to the first lever is connected a link or rod attached to the end of a lever of the
first order pivotted to the hollow frame under the cylinder. This lever (under the
cylinder) is connected to a rod which actuates a lever of the first order over the
cylinder, this lever being connected to an equilibrium or other damper valve in
the flue of the boiler, so that when the pressure of steam in the boiler is excessive
the india rubber disc is forced up and the damper is closed, and when the pressure
of steam is lowered the damper is opened.
If found advisable in practise a perforated plate or plates will be placed in the
boiler above the disc so as to prevent the churning of the water.
The motor is a rotatory disc engine, consisting, firstly, of a shaft which is hollow
to form a steam passage to convey the steam from the steam pipe to the disc, the
said hollow shaft (or hollow end of the shaft) carrying at one end the disc, and
[Price 2d1

casing in which the shaft rotates, the said casing being connected to the boiler or
steam generator and provided with glands, bushes, and packing of ordinary
construction, in which the shaft rotates and which prevents the escape of the steam
from between the shaft and the casing; the hollow shaft is perforated radially to
admit the steam from the casing and steam pipe, and is fitted with a perforated
bush or ring to ensure a continuous opening between the steam pipe and hollow
shaft, so that the disc can be fed regularly with steam when the engine is at work;
thirdly, of a hollow disc perforated from the circumference to the hollow axis in
such a manner as to get the maximum effect from the issuing therefrom of the
steam. The disc is secured to or forms part of the hollow shaft above described, and
is placed within the boiler or steam generator below the level of the surface of the
water therein.
In carrying into practical use my Invention, steam is generated in the boiler
which is conveyed to the casing of the disc engine, thence through the hollow shaft
to the disc and issues through the holes in the circumferential face thereof, the
steam striking the water tangentially or otherwise and causing the disc, shaft, and
strap pulley, or coupling to rotate. By these means and apparatus the steam
generator in the boiler is used over and over again and not allowed to escape into
the atmosphere as is the case with steam motors of ordinary construction.
