#1 The Hypocycloidal design always intrigued me as I could not see any valid reason for going to such extremes when a simple crank would suffice - that was until I discovered that this was to work around various patents that had been lodged covering the crankshaft.

The hypocycloid is a special kind of hypotrochoid, which is a particular kind of roulette . A hypocycloid with three cusps is known as a deltoid . A hypocycloid curve with four cusps is known as an astroid . The hypocycloid with two "cusps" is a degenerate but still very interesting case, known as the Tusi couple . Relationship to group theory

Murray's Hypocycloidal Engine, now in Thinktank, Birmingham Science Museum, England, was made around 1805 [1] and is the world's third-oldest working steam engine [2] and the oldest working engine with a Tusi couple hypocycloidal straight line mechanism. [a] History

The engine was discovered by Henry Ford in 1928 at The Bradley Foundry in Stourbridge, England. It features Murray's 1802 invention of the Hypocycloidal Gear motion which converts the linear force of the piston and rod movement to rotary motion driving the pumps and flywheel. Murray developed this method to circumvent the control of steam.

The unique hypocycloid gear arrangement allowed the piston and connecting rod to move in a straight line creating a perfect sinusoidal motion, without any side loads. In this work, the Wiseman hypocycloid engine was modeled in a commercial engine simulation software and compared to slider-crank engine of the same size.

The original 30cc Wiseman engine produced less torque than the slider-crank engine. because its piston was set higher, providing less combustion volume. Similar to the relationship between torque.

Hypocycloidal Engine. A conventional four-stroke spark-ignition reciprocating engine employs a simple cranking mechanism with a crank pin that revolves in a circle, causing the pistons to undergo a periodic motion consisting of four "strokes" of equal lengths. These four strokes are. Intake : A mixture of air and fuel is drawn into the cylinder.

The engine uses a hypocycloidal planetary gear arrangement to keep the shaft perfectly vertical at all times. The hypocycloidal gears provide a system for guiding the piston rod in a straight line, as the double-acting piston travels through its cylinder. The piston has a 1-1/2" stroke, and the cylinder has a 3/4" bore.

This Matthew Murray hypocycloidal steam engine with planetary gear drive was originally designed in 1802. Birk Petersen created a vast array of projects over his lifetime, ranging from miniature engines to hand-cranked animations and more. He built functional miniatures like a 1/3 scale Gatling gun or a 1/4 scale Case steam tractor, but he also.

Matthew Murray (1765 - 20 February 1826) was an English steam engine and machine tool manufacturer, who designed and built the first commercially viable steam locomotive, the twin-cylinder Salamanca in 1812. He was an innovative designer in many fields, including steam engines, machine tools and machinery for the textile industry . Early years

The conceptual Wiseman Engine is shown in Figure 5(a). As discussed earlier, the path of the crankpin in the Wiseman engine is hypocycloidal instead of circular. This provides the advantages such as longer power stroke, straight line motion better performance, and less wear. 2. Software simulations

There are two versions of Murray's 1802 Hypocycloidal Steam Engine available to model engineers. Anthony Mount's version is available from Polly Model Engineering, and this version shown by Mrs Domieo at Bristol in 2019 is from Cotswold Heritage. Murray's engine was one of a number of designs produced after Boulton & Watt patents expired.
