of the Commissioners of Patents, with his Petition, on the 2nd Septem-
ber 1864.
J, NICHOLAS STUBBER, of Dublin, Ireland, do hereby declare the nature of
the said Invention for "IMPROVEMENTS IN THE APPLICATION OF THE SCREW AND
WORM AND SCREW AND PINION WHEEL OR ENDLESS SCREW AND WHEEL FOR PRO-
PELLING CARS, CARTS, CARRIAGES, RAILWAY CARRIAGES, AND ALL DESCRIPTION OF
LAND CONVEYANCES, AND MULTIPLYING THE POWER OF STEAM, WATER, ATMC-
SPHERIC, AND ALL OTHER MOTIVE-POWER ENGINES AND MACHINERY," to be as
follows:-
By these improvements I obtain from the use of a metallic or other screw
power to propel all description of land carriages, and increase the effective
power of all description of motive-power engines and machinery.
The first part of my Invention consists of a metallic or other screw attached
to the body, axle, or shaft of the carriage or machinery to be propelled or
driven. This screw is set and worked horizontally or vertically in a suitable
frame, or attached by other suitable means to the carriage, conveyance, or
engine to be propelled. This screw is then connected at one end with the
shafts or wheels of the carriage, conveyance, or engine to be propelled by cog
or bevel wheels, endless screw, or worm and wheel, and the other end of the
driving screw is connected with the second or other shaft of the carriage,
engine, or machinery by means of an endless screw or by a cog wheel or
pinion or endless screw and wheel, by which the power of the connecting or
driving screw is imparted to the axle, shaft, or other part of the carriage, con-

page_text: veyance, engine, or machinery to bo propelled. The cog or other wheel used
to drive the main or driving screw may be placed on the axle, shaft, or wheel
of the carriage, conveyance, engine, or machinery to be propelled.
Secondly, whero I use the screw as herein described to multiply the power
of any motive-power engine or machinery, I place the driving screw in a b
suitable position to impart its power to the piston rod, guide rod, shaft, or
other part of the engine or machinery to be propelled, and work the driving
screw horizontally or vertically as herein-before described, or by means of
suitable rack and pinion wheels, so that the power of the screw may be given
to the piston shaft or wheel in its forward and backward or upward and 1
downward motions.
Subjoined are the Drawings and references of my Invention described in
the foregoing Specification.
DRAWINGS AND DESCRIPTION.
Fig. 1 shows a side elevation, and Fig. 2 a plan of a truck with the pro- 1
pelling apparatus attached thereto.
a is a bevilled pinion on one of the axles of the truck; a' is another bevilled
pinion gearing into and driven by the pinion a, and is keyed fast on the
countershaft b. At the other end of the countershaft 6 is a scrow wheel c,
which gears into and drives the other screw wheel c' on the other axle of the 2
truck. The wheels and pinion are so proportioned to each other as to give
the required number of revolutions to the axles; d, d, are bearings fastened
to the bottom of the truck to support the countershaft b.
