Year: 1883

page_text: LETTERS PATENT to Frank Walter Scott of 44 Christian Street, Commercial
15
Road East in the County of Middlesex, Engineer. for an Invention of
IMPROVEMENTS IN MOTORS OR AUXILIARY ENGINES FOR LIFTING STEERING OR
OTHER PURPOSES
"
PROVISIONAL SPECIFICATION left by the said Frank Walter Scott at the
Office of the Commissioners of Patents on the 17th August 1883.
FRANK WALTER SCOTT of 44 Christian Street, Commercial Road East in the
County of Middlesex Engineer "IMPROVEMENTS IN MOTORS OR AUXILIARY
ENGINES FOR LIFTING STEERING OR OTHER PURPOSES."
"
My invention relates to motors or auxiliary engines applicable to lifting steering
and other purposes in which an intermittent motion is required, and consists in tho
use of a cylinder with two single-acting pistons united by a rack gearing with a
pinion on the shaft of the pitch chain wheel or other suitable means of transmitting
motion.
Steam water or compressed air is admitted through a four-way cock or other
suitable contrivance into a pipe leading to cither end of the cylinder so as to act.on;
either piston as required, and force it towards the pinion in the central part of the
cylinder, which pinion by the motion of the rack is caused to revolve and drive
the pitch chain wheel or other suitable means of transmitting motion as required.
By closing the said four-way cock, the motion is stopped, and by opening the
communication with the reverse end of the cylinder the motion of the driving
parts will be.reversed by the action of the steam water or compressed air on the
other piston.
By means of the above arrangement, the steam or other motive fluid is never
admitted to that part of the cylinder which is between the two pistons, and the
uniting rack is always in compression.
-
The drum or chain or rope wheel for transmitting motion is made of a diameter
suitable for its intended work. The cylinder also is made of suitable length and
diameter as may be required, and it may be fixed either vertically or horizontally
or otherwise-And the pistons may be of suitable construction for working either.
by steam, water, or compressed air.

My Invention relates to motors or auxiliary engines applicable to lifting steering
and other purposes in which an intermittent motion is required and consists in the
use of a cylinder with two single acting, pistons united by a rack gearing with a
pinion on the shaft of the pitch chain wheel or other suitable means of transmitting
motion.
Steam water or compressed air is admitted through a four-way cock or other
suitable contrivance into a pipe leading to either end of the cylinder so as to act on
either piston as required and force it towards the pinion in the central part of the
-cylinder which pinion by the motion of the rack is caused to revolve and drive the
pitch chain wheel or other suitable means of transmitting motion as required.
By closing-the..said-four-way-cock-the motion is stopped-and-by opening the
communication with the reverse end of the cylinder the motion of the driving
parts will be reversed by the action of the steam water or compressed air on the
other piston. By means of the above arrangement the steam or other motive fluid
is never admitted to that part of the cylinder which is between the two pistons
and the uniting rack is always in compression. The drum or chain or rope wheel
for transmitting motion is made of a diameter suitable for its intended work. The
cylinder also is made of suitable length and diameter as may be required and it
may be fixed either vertically or horizontally or otherwise.
And the pistons may be of suitable construction for working either by steam
water or compressed air
In order that my Invention may be fully understood I will proceed to describe
more particularly by the aid of the accompanying Drawings the parts of apparatus
above referred to

page_text: motion with a four way cock or other suitable contrivance for admitting steam
water or compressed air to either end of the cylinder as required substantially as
herein before described.
