By reason of the total capacity of its
cylinders, 1795 cc., the new Meadows engine should have a useful
field of application. In size it is not too large to be
economical, nor yet too small to be capable of pulling a four-seater
small car with considerable liveliness without the need of undue
exertion.
Cast monobloc, the four cylinders have a
bore and stroke of 59 x 120 mm., and are, of course;
water-cooled. A detachable cylinder head is used, and in it
overhead valves, operated by rockers, and enclosed push rods are
situated, the camshaft being within the crankcase.
Overhead valves operated by
enclosed push rods are employed in the new
four-cylinder Meadows engine. A cross-shaft drive
renders the magneto, contact breaker, and rocker arm
assembly. |
Two excellent features in the design of the
engine should ensure smooth running. The first is that the
combustion chambers are completely machined so as to ensure
equal capacity, and the second is that the crankshaft is carried
in three bearings. In respect of the capacity of the latter
important member to perform its work, it is enough to say that
the shaft has been designed by Mr. A. A. Remington, who, for the
last two years, has been engaged on research work dealing with
crankshaft deflection. The shaft of the Meadows engine is of
large dimensions and has stiff webs, and the claim is made that
it will not show appreciable vibration or whip up to 3,000
revolutions per minute.
Lubrication has been well attended to, and
oil is forced to the main and connecting rod bearings and to the
rocker shaft of the overhead valve gear. Die cast white metal bearings are used for the crankshaft and
brass shells lined with white metal for the connecting rods. The
gudgeon pins are clamped in the connecting rod small ends.
In order to ensure accessibility for the
magneto a cross-shaft drive at the front of the engine is
provided, and there is also an enclosed gear drive for the
lighting dynamo. This engine, with either three or four-point
attachment, makes a very attractive unit with a four-speed
gearbox and a leather-faced cone clutch, the unit carrying also
the pedals. The makers are Henry Meadows, Limited, Fallings
Park, Wolverhampton.
