page_text: I, JOB BRINE of 4 Hancock Road, Bromley-by-Bow, in the county of Middlesex,
Engineer do hereby declare the nature of this invention to be as follows:-
My invention consists in obtaining the gas necessary to form the explosive
charge at the back of the piston, from the jet which explodes the said charge,
and in the means for the admission of the said gas, and air, to the cylinder.
The end of the cylinder, at the back of the piston, is provided with two inlet
ports, one of the said ports being for gas and the other for air, and the inner ends
of the said ports are closed by clack valves. A gas jet is arranged in front of the
gas inlet port and to the cylinder is secured a hood or dome enclosing the said gas
jet and the gas port. The air inlet port is arranged in any convenient position
outside the said hood or dome and the clack valves of both ports are provided with
suitable means for regulating the admission of the gas and air to the cylinder.
The said hood or dome being closed at its upper end it becomes charged with
unconsumed gas.
As the piston commences its forward stroke the clack valves
open and the said unconsumed gas is drawn into the cylinder, together with air
through the air inlet port, and the flame of the gas jet, which explodes the charge.
The explosion thus produced closes the clack valves until the commencement of the
next forward stroke. The exhaust port is at the bottom or side of the cylinder
and is opened and closed by a slide or gridiron valve operated by a tappet motion.

page_text: I JOB BRINE of 4 Hancock Road, Bromley-by-Bow in the County of Middlesex,
Engineer, do hereby declare the nature of my said invention for "IMPROVEMENTS
IN GAS-ENGINES" and in what manner the same is to be performed, to be par-
ticularly described and ascertained in and by the following statement, reference
being had to the accompanying drawing forming a part of this specification :-

My invention consists in obtaining the gas necessary to form the explosive
charge at the back of the piston, from the jet which explodes the said charge,
and in the means for the admission of the said gas and air to the cylinder.

DESCRIPTION OF THE DRAWING.
Figure 1 is a side elevation, partly in section, of a horizontal gas-engine showing
my improvements.
Figure 2 is an end elevation of the same.
Figure 3 is a view of the inside of the end of the cylinder showing the valves
closing the ports.
Figure 4 is a plan of the bottom of the hood enclosing the gas-port and gas-jet.
Like letters indicate like parts in all the figures.
The end of the cylinder A at the back of the piston is provided with one, two or
more inlet ports B B for air, and an inlet port for gas, the inner ends of the said
ports being closed by clack valves B₁ B¹ and C¹. A gas-jet D is arranged about
in front of the gas inlet port C, the size of the said gas-jet being in proportion to
the power of the engine. I have found a three eighths of an inch gas-jet to give
sufficient gas for an engine of one horse power. To the cylinder end is bolted or
otherwise suitably. secured a hood E enclosing the gas-port C and the gas-jet D the
said hood being closed air-tight on all sides except the bottom. The said hood has
à perforated bottom, as shown in figure 4, the edges of which are turned up so as
to clip the lower edges of the hood, and so that the said bottom can slide on to the
said hood, a slote being formed in the bottom to admit the gas-jet D. The air inlet
ports B B may be arranged in any convenient positions outside the hood E and the
clack valves of both the gas and air inlet ports are provided with screws B³, C³ by
which the admission of the gas and air to the cylinder can be regulated.
The hood E being closed air-tight on all sides except at the bottom and the
perforations in the said bottom admitting only a very small quantity of oxygen to
the flame, only a very small proportion of the gas from the jet D is consumed
and the said hood consequently becomes charged with unconsumed gas As the
piston F commences its forward stroke the clack valves B¹ B₁ C¹ open, and the said
unconsumed gas is drawn into the cylinder together with air through the air inlet
ports B B and the flame of the gas-jet D, which explodes the charge. The explo-
sion thus produced closes the clack valves B¹ B¹ C¹ until the commencement of the
next forward stroke.

page_text: The exhaust-port G is shown at the bottom of the cylinder, but it may be at the
bottom or at the side of the cylinder. It is opened and closed by a slide or gridiron
valve operated by a tappet motion as shown, so arranged that the exhaust-port is
opened instantly before the return stroke of the piston and closed at the completion
of the return stroke.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed I declare that what
I claim is:-
:-
In a gas engine, the hood E, enclosing the gas inlet port C and a gas-jet D,
substantially as berein set forth.
