PROVISIONAL SPECIFICATION.
An Improved Oil, Spirit, Gas, or Steam Motor.
I, WILLIAM PULLEN of King Cross, Halifax, in the County of York, Engineer,
do hereby declare the nature of this invention, to be as follows:-
I employ a main cylinder connected to which is a second smaller cylinder,
within both the cylinders are rotary discs, the one in the large cylinder being
provided with two lugs preferably detachable.
The upper disc having recesses or chambers preferably semicircular.
The two discs are geared together from their respective shafts by pinion wheels
of equal size, the peripheries of the discs just touching, forming an explosion
chamber upon each side of the discs within the large cylinder, with inlets for the
gas which is preferably ignited by incandescent platinum tube.
The action is as follows:-The explosion drives round the disc in the larger
cylinder which imparts its motion to the other disc, as the lugs come round the
recesses in the other disc allow of their passage, when the first lug has passed round
it opens the gas inlet and admits another charge of gas and closing the valve
ignites it by means of the lug passing the platinum tube, and is again driven round.
The gas supply may be forced in by pump, bellows or other means and the valve
operated by means of a cam upon either shaft, the cam operating a plate to which
is attached a governor so regulating the supply, an exhaust is formed at the bottom
or other suitable part.
When the engine is driven by steam one lug only is required and one recess
in the top disc, with steam valve, and inlet into large cylinder, also exhaust for
regulating the cut off, the steam valve being driven from the shaft, and governors
driven from any convenient position.

COMPLETE SPECIFICATION.
An Improved Oil, Spirit, Gas, or Steam Motor.
I, WILLIAM PULLEN of Bristol Street Birmingham in the County of
Warwick Engineer late of King Cross Halifax in the County of York do hereby
declare the nature of my said invention and in what manner the same is to
be performed to be particularly described and ascertained in and by the following
statement :-
My invention has for its object an improved oil, spirit, gas, or steam motor, which
is most simple in action cheap in construction and by which a great amount of
power is obtained in the most econimical manner.
In order that my invention may be clearly understood & more easily carried
into practise I have appended hereunto two large sized sheets of drawings upon
which I have fully illustrated the nature of my said improvements.
Figure is a longitudinal section through one of my double rotary steam
engines.
Figure 2, is a front elevation of same.
Figure 3, is a plan of Figure 1.
Figure 4, is a section through a single rotary engine.
Figure 5. is a similar section but shewing a motor or engine suitable for being

page_text: Figure 6, is an enlarged elevation of one of the lugs B.
Figure 7, is a section through same on the line Z Figures 4 and 5.
In carrying my invention into effect I employ either one or two main cylinderical
compartments B as may be by reason of either a single or double motor being
required and connected with either one or both of these chambers is the smaller
part cylinder D. Within the larger chambers the revolving drums or discs E are
mounted each on carrying the lug F which is preferably detachable. Within the
smaller chamber or cylinder D the revolving disc or drum H is mounted being
provided with the recess or chamber of preferably semicircular shape. The
drums or discs E and H are geared together from their respective shafts by the
pinion wheels e¹ and 2 which are of equal size the peripheries of the said drums
just touching and thus forming a chamber B into which the steam enters by the
inlets K from an ordinary steam valve L the exhaust steam passing out at M into
the jacket N formed around the motor while the steam valve is operated from one
of the main shafts e² the fly wheel O being also mounted on one of these shafts.
For the purpose of preventing an escape of steam or other power from one side of
the chamber to the other, the lug F is provided with the loose nose piece which
is operated by expansion coil springs f2 so as to constantly press against the interior
of the chamber in its travel the wear also being thus taken up similar plates f³
operated by springs f being placed at the ends of lugs to press against the side
plates of the chamber. Loose rings e operated by springs et are also placed around
the side faces of the drums or discs E and H so as to press against the outer side
plate of the chamber B. The reversing of the double motor may be effected by
means of the hand lever P Figure 2 which is connected with the inlet K thus
turning the plugs k¹ until the inlet is reversed to the opposite side. In the case of
gas motors as shewn at Figure 5 an explosion chamber B³ is formed with inlet 64
for the gas which is preferably ignited by the platinum tube 6 which rendered
incandescent by the flame 60 a suitable governor be provided for regulating the
supply.
Having now particularly described an ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is
The new
or improved rotary engine or motor substantially as and for the
purpose herein set forth and shewn upon the accompanying drawings.
