NEW WAY Governors

GOVERNING GENERAL

New Way used two principle methods to govern their Motors. Early models were "Hit and Miss" and later  throttle governed. As a general rule for motor manufacturers of the era, the actuating force for control is centrifugal force. The principle of operational control for these two systems is vastly different.

A possible exception was the single cylinder verticals (BH and FH) that used an Air Governor. 

New Way Hit Miss Governed Engines included Little Giant, Jewels, Vertical Type "C", Vertical type "D", Horizontal twins, Horizontal Standard and some vertical Series "M".

• Hit Miss Governor  - the mixture volume is essentially fixed and speed governed by controlling its intake frequency and consequently the firing of the mixture. Loading the motor means the revs tend to drop off, the exhaust valve is allowed to close by the governor, fuel/air is taken in and fired to again increase the revs to set RPM. An intake mixture "Hit" may drive the motor over several "Miss"cycles until another Hit is required to maintain revs. Exhaust Valve operation is the primary control since the mixer/carburetor is always fully open (ie equivalent to full throttle) . 
• Early Model Adjustment - Motor Revs. control - Made by evenly adjusting 2 screws at the centre of the governor flywheel to vary spring load pressure and effect the travel of governor weights for controlling the latching of the exhaust valve. Higher the spring loading the higher the revs before the governor cuts in.

Throttle governed engines were produced from about the mid teens (1900) and included some Vertical Series "M". I believe throttle governing applied to models BH(A), CH(A), DH(A), FH(A), EHA and GHA. These were the physically small, flywheel fan, single and Twin cylinder vertical engines ranging in size from 3 to 10 Hp.

• Throttle Governors - the mixture volume is varied generally by a centrifugally actuated throttle control for the carburettor which gives finer control on the governed speed of the motor than is possible with the Hit Miss process. The throttle merely varies the volume of intake mixture which directly effects the volume of fuel and therefore speed. Loading the motor means speed drops off, the throttle is opened and therefore more fuel and air is supplied to maintain revs through all intake strokes. Throttle position is the primary control.

Restorers - I am looking for model specific tips or help for any of the throttle governors / engines to publish for others to use in their projects. Detail on the Air governor operation also appreciated.
