DOUBLE ACTING ENGINE

Double Acting Engine  Steam Inlet Mechanism & Distribution Device  Experiments by Other Inventors  Principle of Double Acting  Planet Gear & Parallel Motion  Cutoff Valve & Governor  Industrial Uses of Steam  Summary - Development of Engine

Steam Inlet Mechanism  Large Engine of Watt Used Condenser  For Cost Reasons  Steam Entered Steam-Jacket  Entered and Evacuated at Bottom  Exited Towards Condenser  Condenser Connected to Suction Pump

Inlet Mechanism - Single Acting Engine

Steam Distribution Device  Watt (1778)  Steam Enters Cylinder at Bottom - Piston Rises  Steam Evacuated To Condenser - Piston Lowers  Newcomen (7 psi), Watt (10 psi)  Watt (1780)  Led to Double Acting - Reversed Operation  Constant Steam Pressure Under Piston  Alternating Pressure & Vacuum Above Piston  Did Not Change Operating Principle  Vacuum Was Still Driving Force  Not Satisfactory - Led to Double Acting

Steam Distribution - Watt (1778)

Steam Distribution - Watt (1780)

Experiments by Other Inventors  Jacob Leopold (1724)  Two Newcomen-Type Cylinders  Four-Way Cock  Steam Pressure Higher Than Atmospheric  Jonathan Hull (1736)  Paddle Wheel in Continuous Motion  Ratchet Mechanism  Opposite Direction With Counter Weight

 Continuous Movement (competing with Watt)  Keane Fitzgerald (1759)  John Stewart (1777)  Matthew Washborough (1779)  James Pickard (1780)  Thompson (1793) & Sherrats (1794)  Double Acting - Two Alternating Cylinders  E. Cartwright (1797)  Closed Circuit  Two Gears - Flywheel Experiments by Other Inventors (continued)

Atmospheric Engine - Leopold (1724)

Atmospheric Engine - Hull (1736)

Rotary Engine - Cartwright (1797)

Planet Gear & Parallel Motion  Planet Gear - Watt (1781)  Crankshaft & Connecting Rod  Matthew Washborough (1779)  James Pickard (1780)  Epicyclic Gear Train  Watt’s Sun and Planet Gear  Parallel Motion - Watt (1784)  Tried Rack & Pinion  Chains Previously  “O” is Center of Beam  “A” is Fixed  “B” & “C” are Attached to Piston Rods

Planet Gear - Watt (1781)

Parallel Motion - Watt (1784) A

Cutoff Valve  Previously Steam Pressure Was Used Throughout The Stroke  Watt (1769)  Stop Supply Of Steam Before End Of Stoke  Utilize Steam Expansion For Last Portion Of Stroke  Absorbed Shock of Piston At End Of Stroke  Total Power of Engine Decreased  Economy Of Steam To Produce Same Work  Patent - Watt (1782)

Governor  Last Of Watt’s Great Inventions  Speed Governor  Limited Opening Of Valves  Controlled Steam Flow  Slowed Down Engine  No Patent - Used In A More Primitive Form In Grain Mills

Governor With Fly-Balls (1784)

Industrial Uses of Steam  Boulton & Watt ( )  Soho Factory - Built 500 Engines  1/3 Were Pumping Engines  2/3 Were Double Acting  Averaged 15 hp  After 1800 Watt’s Patents Went Public  Great Britain & Ireland (1817)  20,000 hp In Cotton Mills  Glasgow (1825)  310 Steam Engines

Double Acting Rotative Engine - Boulton & Watt ( )

Summary of Development of Steam Engine  Papin (1690)  Savery (1698)  Newcomen  Watt - Condenser (1769)  Watt - Double Acting (1784)  Woolf - Double Expansion (1803)
