PROVISIONAL SPECIFICATION.
Improvements in Gas and similar Motor Engines.
I, ALFRED ROWE BELLAMY, of Algoa Lodge, Adswood Lane, Stockport, in
the County of Chester, Engineer, do hereby declare the nature of this invention to
be as follows:-
My invention relates to gas and similar motor engines in which two power
cylinders are employed, and the object of my invention is to improve the con-
struction and remedy certain defects which now exist in large gas engines having
more than one cylinder.
According to my improvements I place the cylinders tandem one behind the
other with the cylinders, crosshead guides and crankshaft all mounted upon one
long bed-plate, the crankshaft having preferably a bearing on each side of the bed;
the connecting rod from the crank is pivoted to a crosshead mounted in suitable
guide ways and one piston rod is connected to this crosshead. To each end of
the crosshead is secured a rod and these rods are connected at their other ends
to a crosshead for the piston rod of the other cylinder, which second crosshead
also works in guide ways on the bed plate.
Each cylinder is provided with its own arrangement of valves for admitting
the explosive fluid mixture, igniting the same, and exhausting the products of
combustion, all the valves being operated preferably by a single side shaft driven
from the crankshaft; the pistons occupy the same relative positions in each
cylinder and the valves are arranged so that the explosions in the cylinders take
place alternately and thus tend to ensure an explosion at each revolution of the
crankshaft.
Although I have spoken of two cylinders only it might be desirable to use
more than two.
Dated this 5th day of April 1893.

COMPLETE SPECIFICATION.
Improvements in Gas and similar Motor Engines.
J, ALFRED Rowe Bellamy, of Algoa Lodge, Adswood Lane, Stockport, in
the County of Chester, 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 gas and similar motor engines in which two power
cylinders are employed, and the object of my invention is to improve the con-
struction and remedy certain defects which now exist in large gas engines having
more than one cylinder.
I attain this object by the improved combination and novel arrangement of the
parts hereinafter described with reference to the accompanying sheet of drawings
in which :-
Figure 1 is a side elevation and Fig. 2 a plan of a gas or similar motor engine
constructed and arranged according to my invention.
I place the cylinders a a¹ tandem, one behind the other, with the cylinders,
crosshead guides 6 6¹ and crankshaft c all mounted upon one long bedplate d, the

page_text: The
crankshafte having preferably a. bearing e upon each side of the bed.
connecting rod f from the crank is pivoted to a crosshead g mounted in suitable
guide ways h, and one piston rod is connected to this crosshead g. To each end
of the crosshead g is secured a rod k, and these rods k- are connected at their
other ends to the crosshead g' for the piston rod ¹ of the other cylinder a³, and
this second crosshead g also works in guide ways h¹ on the bedplate. Each
cylinder a a¹ is provided with its own arrangement of valves for admitting the
explosive fluid mixture, igniting the same, and exhausting the products of com-
bustion, all the valves being operated preferably by a single side shaft m driven
from the crankshaft c. The pistons (not shown) occupy the same relative positions
in each cylinder a a', and the valves are arranged so that the explosions také
place alternately, and thus tend to insure an explosion at each revolution of the
crankshaft.
Although I have only shown and described two cylinders a a¹ it might be
desirable and would be quite practicable to use more than two..
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed declare that what I
claim is :-
In a gas or similar motor engine the combination, and general arrangement of
parts embodying and constituting my improvements substantially as herein
described and as illustrated by the drawings.
Dated this 5th day of January 1894.
