PROVISIONAL SPECIFICATION.
Improvements in Machinery for Obtaining Motive Power.
We, GEORGE ROBINSON of 42 Manor Road, Brockley, in the County of
Kent, Engineer, and CHARLES DRISCOLL TUSTIN of 156 Deumark Hill in the
County of London, Color Manufacturer, do hereby declare the nature of this
invention to be as follows:-
The object of this invention is to produce machinery capable (when having
received a first impulse if necessary) of renewing and keeping up its own motion
without the exercise of supplemental or external power, and to render such
machinery capable of imparting motion applicable to general purposes.
According to this invention there is provided a vertical shaft capable of
rotation in bearings and also capable of a slight motion in the direction of its
axis; upon this shaft is keyed a cylinder having a screw thread thereon. This
screw thread upon the cylinder is or may be formed of a series of rollers mounted
upon pins which are normal to the surface of the cylinder, or the thread may be
without rollers.
This screw thread gears with a toothed wheel upon one side, the toothed wheel
being keyed upon a horizontal shaft carried in bearings upon the framework of the
machine. Upon the same shaft is keyed a bevel wheel, gearing into a bevel
pinion on a vertical countershaft, which carries a spur wheel. The latter spur
wheel gears with a pinion mounted upon the vertical screw shaft.
Upon the opposite side of the screw threaded cylinder, there is a second
horizontal shaft mounted in bearings upon the framework, and this shaft carries a
toothed wheel gearing with the screw and a bevel wheel, which latter gears with
a bevel pinion on a second countershaft, upon which is a second spur wheel
gearing with the pinion on the vertical screw shaft. Thus the gearing upon one
side of the screw shaft is symmetrical with the gearing on the other side
thereof.
Above the vertical screw shaft aud fulcrummed on a bracket on the framework,
is a weighted lever, spring or equivalent, to produce a downward pressure
(regulated as circumstances may require, in a proper degree) upon the vertical
shaft, whereby the latter is caused to rotate the spur wheels (upon the horizontal
shafts) with which it is in gear, and these in turn through the gearing before
described rotate the screw shaft; in this manner the movements of the parts of
the machine follow one another in rotation or in cycle. By this construction the
machine having been started will continue in motion so long as no excessive
pressure is applied.
In order to regulate the vertical position of the screw shaft, a vertical adjustment
mechanism is provided, as, for example, below the lower end of the vertical shaft,
is a plunger capable of being raised or lowered by means of a screwed spindle
operated through gearing from a hand wheel. By raising the plunger and lifting
the screw out of contact with the teeth of the spur wheels, that is, relieving the
driven spur wheels from the downward pressure of the screw, the machine will
be deprived of its motive power, and by allowing the vertical shaft to descend by
the adjusting mechanism, and again bringing pressure upon the toothed wheels,
the machine is again put into motion.

page_text: The screw thread or rollers of such thread may be formed of metal, and the
teeth of the driven wheels of wood or metal or a combination of the same.
Motion may be transmitted from any convenient shaft of the machine for driving
any required mechanism.
The machine, or parts of same, may be constructed of any desired suitable
material according to the purpose for which it is designed to be used.

Machinery for Obtaining Motive Power.
We, GEORGE ROBINSON of 42 Manor Road, Brockley, in the County of Kent,
Engineer, and CHARLES DRISCOLL TUSTIN of 156 Deumark Hill, in the County
of London, Color Manufacturer, do hereby declare the nature of this invention
and in what manner the same is to be performed to be particularly described
and ascertained in and by the following statement :-
The object of this invention is to produce machinery capable (when having
received a first impulse if necessary) of renewing and keeping up its own motion
without the exercise of supplemental or external power, and to render such
machinery capable of imparting motion applicable to general purposes.
In order that our invention may be readily understood we will describe same
with reference to the accompanying drawing, on which is shewn a side elevation
of a machine constructed according to our said invention.
In carrying out this invention there is provided a vertical shaft A capable of
rotation in bearings B carried by a suitable framework such as C, and the vertical
shaft A is also capable of a slight motion in the direction of its axis; upon this
shaft A is keyed a cylinder D having a screw thread or threads thereon. This
screw thread (or threads) upon the cylinder D is or may be formed of a series of
rollers E mounted upon pins which are normal to the surface of the cylinders D,
or the thread may be without rollers.
This screw thread (or threads) E gears with a toothed wheel F upon one side, the
toothed wheel F being keyed upon a horizontal shaft G carried in bearings H
upon the framework C of the machine. Upon the same shaft G is keyed a bevel
wheel J gearing into a bevel pinion K on a vertical counter shaft L, which carries
a spur wheel M. The latter spur wheel M gears with a pinion A' mounted upon
the vertical screw shaft A.
Upon the opposite side of the screw threaded cylinder D, there is a second
horizontal shaft G¹ mounted in bearings H upon the framework C, and this shaft
carries a toothed wheel F indicated by dotted lines, this wheel F gearing with
the screw E; a bevel wheel J' is also carried by the shaft G', which wheel J¹
gears with a bevel pinion K' on a second counter shaft L', upon which is a second
spur wheel M' gearing with the pinion A' on the vertical screw shaft A. Thus
the gearing upon one side of the screw shaft A is symmetrical with the gearing
on the other side thereof.
Above the vertical screw shaft A and fulcrummed on a bracket N on the
framework, is a weighted lever P, spring or equivalent, to exercise a downward
pressure (regulated as circumstances may require, in a proper degree) upon the
vertical shaft A, whereby the latter is caused to rotate the spur wheels FF(upon
the horizontal shafts G G¹) with which the screw thread E is in gear, and these in
turn through the gearing before described rotate the screw shaft A; in this

page_text: manner the movements of the parts of the machine follow one another in rotation
or in cycle. By this construction the machine having been started will continue
in motion so long as no excessive retarding pressure is applied.
In order to regulate the vertical position of the screw shaft A a vertical
adjustment mechanism is provided; thus for example below the lower end of the
vertical shaft, is a plunger R capable of being raised or lowered by means of a
screwed spindle R¹ operated say by a hand wheel R. By raising the plunger R
and thereby lifting the screw E out of contact with the teeth of the spur
wheels F Fi, that is relieving the driven spur wheels from the downward pressure
of the screw E, the machine will be deprived of its motive power, and by allowing
the vertical shaft A to descend by the adjusting mechanism and again bringing
pressure upon the toothed wheels F F the machine is again put into motion.
The screw thread E or rollers of such thread may be formed of metal and the
teeth of the driven wheels of wood or metal or a combination of the same.
Motion may be transmitted from any convenient shaft of the machine for
driving any required mechanism.
The machine, or parts of same may be constructed of any desired suitable
material according to the purpose for which it is designed to be used.
Having now particularly described and ascertained the nature of our inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
The combination and arrangement of parts composing our mechanism or machine
for obtaining motive power, all constructed and acting substantially as and for the
purposes described and illustrated with reference to the accompanying drawing,
together with any mere modification or modifications thereof.
