  Gear: Definition and Links by Encyclopedian.com
Different-sized gears are often used in pairs, allowing the torque of the driving gear to produce a larger torque in the driven gear at lower speed, or a smaller torque at higher speed.
Regardless of the gear ratio, the amount of power delivered by the output gear cannot exceed the power applied to the input gear, and there is usually a loss of power due to friction.
This is a gear that resembles a screw, with parallel helical teeth, and mates with a normal spur gear.

 Interrupter gear
Synchronization gear, popularly and incorrectly known as interrupter gear, was a triggering device attached to the machine gun of a tractor-type fighter aircraft so that it would fire only at certain times thereby allowing the gun to fire through the arc of a spinning propeller without the bullets striking the blades.
A machine gun fitted with interrupter gear had the trigger normally enabled and the interrupter mechanism would disable the trigger when a propeller blade was in the way.
Eventually all British aircraft were equipped with the superior Constantinesco synchronization gear (or "CC" gear) which used the impulse on a column of liquid instead of a mechanical system of linkages, though it still relied on a cam to initiate the impulse.

 First World War.com - Encyclopedia - Interrupter Gear
Improving upon the French invention of the so-called 'deflector gear', which enabled fighter pilots to use machine guns to fire through aircraft propeller blades, Anton Fokker devised the much-improved interrupter gear in 1915.
The key drawback to the French device - championed by French air ace Roland Garros - was that the machine gun would often fire bullets into the aircraft's propeller blades rather than always through them.
He devised the 'interrupter gear', a timing mechanism whereby the machine gun would only fire through the aircraft propellers, i.e.

While many of these problems associated with other gear have become accepted as obstacles that must be worked around, the PVI supplies an attractive alternative that tackles these limitations head-on.
The resettable Vacuum Interrupter means that fuses are no longer required when the PVI is used in place of most padmount equipment.
In comparing the front-accessible gear to placing all equipment in vaults or basements, the front-accessible gear is significantly less expensive.

What you describe O.P. (correctly I might add) is technically an interrupter, it mechanically prevented the gun from firing when the prop was in a position to be struck.
The slow rate of fire was not the pilot being conservative with his ammunition, it was as expended as fast at the interrupter gear 'prevented' his gun from firing.
Hydraulic fluid was compressed by a pump in pulses off the engine camshaft, via tubing this ran to valve gear at the base of the joystick where the pressure was absorbed by a system of relief valves and chambers.

The first is Synchronization gear, which is often incorrectly referred to as "interrupter gear"; this is a triggering device attached to the machine gun armament of a tractor-type fighter aircraft so that it would fire only at certain times.
The first British aircraft to use a synchronizer gear was the Sopwith 1½ Strutter which arrived in April 1916 equipped with the Ross synchronizer, although some other service types were retrofitted with synchronised guns about this time, including the Nieuport 12 and the Bristol Scout.
Eventually all British aircraft were equipped with the superior hydraulic Constantinesco synchronization gear (or "CC" gear, invented by Romanian engineer George Constantinesco) which used impulses transmitted by a column of liquid instead of a mechanical system of linkages.

However, this was found to be very unsatisfactory, owing to the construction of the gun, and it was found that a much more satisfactory operation could be obtained by having a gear fire the gun at certain points throughout the revolution of the propeller when the blade was not opposite the muzzle of the gun.

Synchronization gear, popularly and incorrectly known as interrupter gear, was a triggering device attached to the machine gun of a tractor-type fighter aircraft so that it would fire only at certain times thereby allowing the gun to fire through the arc of a spinning propeller without the bullets striking the blades.
Introduced during the First World War, the gun synchronizer was a significant development in the history of air combat and remained in operational use until the Korean War.
As aircraft gunsight technology improved, however, the importance of locating the guns in front of the pilot diminished, and many fighters of World War II had wing-mounted guns instead that fired to the sides of the propeller and their bullet trajectories were "harmonised" to converge at a preset distance.
