Daimler Twenty-Two

[2] The following January 1903 Daimler, having earlier dropped the 9 hp, replaced their 12 with a 14-horsepower car making a range of just two vehicles.

Although they were first displayed in April deliveries did not begin until July and a steady production stream did not eventuate until November 1902.

This new range was between 25 and 30 per cent lighter than their preceding equivalents and had much improved speed and hill-climbing power.

The lowered chassis frame increased the cars' stability and made entry easier.

It develops 22 hp at 720 rpm at which speed in top gear the car should be running at between 40 and 50 mph.

The skirt of each piston is reduced slightly in diameter to form an oil retaining space.

The camshaft bearings are part of the crankcase covered by an upper half that is a separate casting and provides a guide for the pushrods.

A half-inch pitch roller chain links the drive to the commutator mounted on the car’s dashboard.

At the opposite end from the valve chamber the tubes project into an enclosed metal casing where they are heated by lamp burners.

After passing through this box the gases are led across the back of the car in a pipe with a perforated underside to minimise the dust stirred up.

Its sides are of ribbed aluminium castings connected by finned tubes run horizontally across the front of the car.

[6] The wooden main frame is strengthened by tapering steel fishplates along the inner faces of the longitudinal members.

[6] The clutch and flywheel are mounted on the back of the engine block This part of the clutch is of aluminium and carries a friction surface of leather To make for a more gradual engagement a steel spring is set between the leather and the metal face.

[2] When the handbrake is applied the (otherwise fixed) end of the spring is moved forward by a cam which releases the clutch and the car may stop without affecting the engine.

The transverse casing of the countershaft the differential and the gearbox is of aluminium alloy and it covers the entire transmission gear.

The transmission has eight ring-lubricator type bearings fed by pipes from feeders with gauge glasses visible from beneath the car.

Power is transmitted from the transverse countershaft to each rear wheel by 1½ inch pitch roller chains.

[2] Four forward speeds separate lever for reverse[2] The foot pedal operates by rod a transmission brake mounted on the rear end of the gearbox's second motion shaft.

The back axle is located by a pair of distance rods fixed to the main frame by the same brackets as the final drive and gearbox.

[2] The body of the King’s car was arranged to carry two on the box at the front and six people behind in the tonneau.

The car is upholstered in blue Morocco leather and the body is painted in crimson lake lined with red.

A driver may now use the braking effect of engine compression because the handbrake no longer automatically disengages the clutch.
