PROVISIONAL SPECIFICATION.
A Combined Gas Motor Engine and Dynamo Electric Machine.
1, FRANCIS WILLIAM CROSSLEY, of Openshaw, Manchester in the County of
Lancaster, Engineer, do hereby declare the nature of this invention to be as follows:-
My invention relates to an arrangement, in simple and compact form, of a combined
gas motor engine, and dynamo-electric machine driven by it. The cylinder of the
gas motor engine being horizontal at one end of the engine frame, whilst the flywheel
shaft revolves in bearings near the other end of the frame, I mount the dynamo-
electric machine upon the upper side of the cylinder, fixing it firmly thereto, the axis
of the machine being paralel to that of the engine shaft. On the spindle of the
dynamo machine I fix a flywheel and a pulley which is driven by a band from the
flywheel of the engine. This band being necessarily short, I provide for tightening it
and extending its bearing on the pulley, by pivolting or fitting on the engine frame a
lever or slide carrying a tightening pulley that bears against the underside of the band
between the flywheel, and the pulley of the dynamo machine. This lever or slide
being strained upwards by a weight or spring or by a setting screw, with or without
a spring, causes the pulley which it carries to bear against and bend the band,
tightening it and giving it more extended contact with the pulley of the dynamo
machine.
Obviously, when the engine is worked with combustible vapour as an oil engine the
same arrangement is applicable.

I, FRANCIS WILLIAM CROSSLEY of Openshaw, Manchester in the County of
Lancaster Engineer 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 :—-
My invention relates to an arrangement in simple and compact form of a combined
gas motor engine and dynamo electric machine driven by it. The cylinder of the gas
motor engine being horizontal at one end of the engine frame, whilst the flywheel
shaft revolves in bearings near the other end of the frame, I mount the dynamo-
electric machine upon the upper side of the cylinder fixing it firmly thereto, the axis
of the machine being parallel to that of the engine shaft. On the spindle of the
dynamo machine I fix a flywheel and a pulley which is driven by a band from tho
flywheel of the engine. This band being necessarily short, I provide for tightening
it and extending its bearing on the pulley by pivotting or fitting on the engine
frame a lever or slide carrying a tightening pulley that bears against the underside of
the band between the flywheel and the pulley of the dynaino machine. This lever or
slide being strained upwards by a weight or spring or by a setting screw, with or
without a spring, causes the pulley which it carries to bear against and bend the band
tightening it and giving it moro extended contact with the pulley of the dynamo
machine. Obviously when the engine is worked with combustible vapour as an oil
engine the same arrangement is applicable.
Fig. 1 of the accompanying drawings shews a sido elevation and Fig. 2 an end
elevation of a combined gas motor engine and dynamo electric machine constructed
according to my above described invention.
The dynamo electric machine A has its framing B mounted upon the cylinder C of
the motor engine, the overhanging pulley D of the armature shaft being driven by
belt E from the flywheel F of the engine which belt is strained by a tightening
pulley G mounted on a lever H pivotted to the engine framing and adjusted by a
scrow I or in some equivalent manner. Jis a flywheel on the arinature shaft.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed 1 declare that what I claim is
A combined gas motor engine and dynamo electric machine wherein the dynamo
electric machine is mounted upon the engine cylinder and is driven by a belt from
the fly wheel strained by a tightening pulley mounted adjustably substantially as
herein described.
